The invention describes an adapter for a handheld machine tool, comprising a locking unit (), which can be releasably and fixedly attached to a housing () of a handheld machine tool, and a rotatably mounted shaft (), which can be connected in a rotationally fixed manner to a drive shaft () of the handheld machine tool, wherein the locking unit () has at least one means () for a latching connection.

Adapter for a hand-held power tool

The invention is based on a device for handheld power tool for detecting a torque, having at least one sensor unit. It is proposed that the sensor unit is intended for detecting a deformation parameter. The sensor unit has at least one sensor element that is embodied as a strain gauge. A gearbox is provided which has a bearing location for receiving a deformation element of the sensor unit. An electronic unit evaluates detected data from the at least one sensor unit.

Handheld power tool device for detecting torque

The invention relates to an energy-transmitting device, for transmitting electrical energy between a handheld power tool and/or a battery unit and/or a charging unit. The energy-transmitting device has at least one pin contact element. It is proposed that the pin contact element is movably supported.

A portable blower having a motor unit that includes a drive motor disposed in an engine housing. The blower has a blower unit that is provided with a blower housing that is separate from the engine housing. The blower unit includes an axial fan that is driven by the drive motor via a drive shaft. During operation the axial fan conveys operating air in the direction of the axis of rotation of the axial fan through a blower tube disposed downstream of the axial fan. An ergonomic operation and a good operating result can be achieved if the motor unit includes a guide tube on which is secured at least one handle. The engine housing is disposed at one end of the guide tube and the blower unit is disposed at the other end of the guide tube. The drive shaft extends through the guide tube. The length of the guide tube between the engine housing and the blower unit corresponds to at least half of the length of the blower tube.

Portable blower

A handheld power tool has a handheld power tool base body, a battery pack that is detachable from the handheld power tool base body, and an inner cavity with a wall that constitutes a coupling region for the coupling of the battery pack to the handheld power tool base body. The wall has at least one shaped component that is oriented outward in relation to the inner cavity.

A battery pack for an electric appliance has a base body, a locking device for locking the base body to the electric appliance, at least one contact element for producing an electrical contact with the electric appliance, and a contact holding unit for holding the contact element. The locking device and the contact holding unit are fastened to the base body by means of a shared fastening module.

A battery pack for an electric appliance has a base body, a locking unit for locking the base body to the electric appliance, an actuating element for unlocking the base body, which element is intended to be actuated by a user in an actuating direction, and a removal direction in which it is possible to remove the base body after it has been unlocked from the electric appliance. The actuating direction has at least one component oriented counter to the removal direction.

Safely removable battery pack

A system for electrically coupling an electrical supply unit for cordless electrical devices, hand-held power tools in particular, with a charging device, with the electrical supply unit is located in a housing in which at least one rechargeable battery that can be recharged using the charging device is located, and the electrical supply unit and the charging device each have at least a first and a second contact element, wherein the first and second contact elements of the electrical supply unit interact with the first and second contact elements of the charging device such that the charging procedure takes place only when the electrical supply unit is in a defined end position in the charging device.
