A portable power tool, in particular an angle grinder, includes a housing that accommodates a drive and an electronic device with an interface configured to electrically connect the electronic device. The power tool further includes a housing inner part that is configured as a drive housing and supports the electronic device. The interface has at least one first electrical interface contact region and at least one second interface contact region spaced apart from the first interface contact region. At least one insulating element spaced apart from the interface contact regions is arranged between the housing inner part and the electronic device. The insulating element is configured to avoid an electrical short-circuiting connection between the first interface contact region and the second interface contact region.

Portable power tool

A hand-held power tool, in particular an angle-grinding machine, includes a housing, a switching unit, a motor, and at least one first pivot unit and one second pivot unit. The switching unit includes a ratchet element arranged on the housing. The first and second pivot units are configured to mount the ratchet element on the housing so as to be movable. Each of the first and the second pivot units includes at least one housing-side bearing unit and one ratchet-side bearing unit. The hand-held power tool further includes a coupling unit configured to couple the first pivot unit with the one second pivot unit.

Hand-held power tool with a switching unit

A machine tool, in particular an angle grinder, includes at least one switching unit that has at least one movably mounted ratchet element and at least one release element for unlocking a movement preventer of the ratchet element. The release element has at least one actuating region that is at least partially arranged laterally alongside an operating area of the ratchet element.

Machine tool

A machine tool includes at least one handle housing having at least one switching unit with at least one ratchet element arranged on the at least one handle housing and at least one bearing unit, which is provided to support the at least one ratchet element at least movably relative to the at least one handle housing. The at least one bearing unit includes at least one lever drive unit, which is provided in order to enable a uniform stroke motion over an entire operating surface of the at least one ratchet element during an actuation of the at least one ratchet element.

A power tool, in particular an angle grinder, includes at least one switching unit which has at least one pivotably mounted pawl element. The pawl element defines a pivot axis. The pawl element is mounted so as to pivot about the pivot axis of the pawl element through an angular range greater than 30&#xb0;.

Power tool

A protective hood rotation prevention device for a power tool, in particular an angle grinder, includes a clamping unit that is configured to clamp a protective hood unit. The clamping unit includes at least one clamping element with a rotation prevention unit that has a rotation prevention element. The device further includes a movement coupling unit that is configured to move the rotation prevention element in at least one operating state depending on a movement of the clamping element. The device also includes a securing unit that is configured, in at least one operating state, to secure the rotation prevention element, in the event of a movement of the clamping element in a loosening direction of the clamping element, at least as far as possible counter to a movement in an uncoupling direction of the rotation prevention element out of a rotation prevention position of the rotation prevention element.

Protective hood rotation prevention device

A power tool, especially an angle grinder, includes at least one grip housing, at least one switching unit that has at least one latch element arranged on the grip housing, and at least one bearing unit configured to mount the latch element such that it is mobile at least with respect to the grip housing. When the latch element is actuated, the bearing unit is configured to guarantee a stroke movement of the latch element along a trajectory of a value greater zero, starting from an end of the latch element closer to the connecting region of the grip housing in the direction of an end of the latch element away from the connecting region, which end is configured to be gripped.

A power tool includes at least one grip housing having at least one handle-shaped grip region and at least one switching unit having at least one movably mounted latch element. The at least one movably mounted latch element has a maximum width that extends over at least a major part of at least one maximum width of the at least one handle-shaped grip region of the at least one grip housing.

The invention relates to a cable sleeve for guiding a cable in the inlet and outlet region of a hand-held tool. An end of the cable sleeve on the housing side is connected to the housing in a fixable manner, particularly in a form-fitting manner, so that advantageously no dust, dirt, or water may enter between the cable sleeve and the cable. According to the invention the cable sleeve has preferably a radial sealing element which corresponds to the cable and/or the housing in a sealing manner.

Cable sleeve for a hand-held power tool

A system for a hand-held power tool has a tool housing, a receiving unit fixed to the tool housing and a guard unit connected with the hand-held power tool. The guard unit includes a guard extending at least partially around a rotatable tool. A guard anti-rotation lock device includes a clamping band fixedly connected to the guard that establishes a frictional connection between the guard unit and the receiving unit. The receiving unit includes a receiving flange and a connecting element that are together surrounded by and clamped in a clamping region by the clamping band to effect the frictional connection. In a case where the rotatable tool bursts into pieces during operation, the connecting element counteracts rotational movement of the guard unit with respect to the receiving unit by changing a cross-sectional shape of the clamping region.

Guard anti-rotation lock

The invention relates to a hand-held power tool, particularly an angle grinder having a housing that has a flange neck, having a protective device that can be accommodated on the flange neck and that can be pivoted in the circumferential direction, and having at least one device for blocking at least one pivoting direction of the protective device. The invention proposes that the device for locking includes at least one stop and at least one counter-stop interacting with the stop.

Hand-held power tool

The invention relates to a protective hood anti-rotation lock for a portable power tool (-), especially an angle grinder. Said protective hood anti-rotation lock is characterized in that it comprises an anti-rotation unit (-) that is adapted to take into consideration at least one operating parameter of the portable power tool (-) during anti-rotational locking.

The invention relates to a protective hood securing device for a portable power tool (), especially an angle grinder. Said protective hood securing device comprises a protective hood unit (), having a protective hood (), and a securing unit () having at least one securing element () which is provided together with the protective hood unit () for protection in the event of a tool () breakage. For this purpose, the securing element () is at least partially configured by a protective cover () that is provided in addition to the protective hood ().

Guard lock

An adapter part for a machine tool is designed to be inserted between two housing parts and includes an adapter connection element that corresponds to a housing connection element on a housing part.

Adapter part for a machine tool

A hand-held power tool system has a hand-held power tool, a guard unit, and a guard anti-rotation lock unit configured to prevent rotation between the guard unit and the hand-held power tool in a case where a tool of the hand-held power tool breaks during intended operation. The guard anti-rotation lock unit also is configured to prevent rotation between the guard unit and the hand-held power tool at a same time as the guard unit is attached to the hand-held power unit, when the guard unit is in a working position. Preferably, the guard anti-rotation lock unit is at least partially located on a closing unit which includes a clamping band and a pivotable lever. The anti-rotation lock unit preferably includes an anti-rotation lock element provided on the lever.
