Saw blade

A transmission device is configured to generate at least one of a stroke motion and a reciprocating motion of an insert tool of a hand-held power tool, and includes at least one link unit configured to generate the stroke motion. The link unit includes at least one output element, at least one link element, at least one contact surface, and at least one further contact surface. The at least one contact surface is disposed at least partially on the at least one output element. The at least one link element is configured to act in combination with the at least one output element via the at least one contact surface. The at least one further contact surface is configured to generate a force that initiates the reciprocating motion, and is disposed at least partially on the at least one output element.

Transmission device

The invention relates to a handheld tool, in particular a handheld saw, with an electric drive motor (), a serially switched gearbox (), and a movement converter () that converts the driven movement of the gearbox () into an axial to-and-fro movement of a lifting element () for driving a tool (), in particular a saw blade, inside a housing (). The gearbox () and the movement converter () are combined into a gear unit (). The gear unit () is within a robust, bending- and deformation-resistant gear housing (), which is in turn inside the housing (). The housing () is made of flexible plastic.

Handheld power tool, in particular handheld power saw

A hand-held power jigsaw includes a clamping device which has an insertion slot () for a shaft () of the tool and has a transverse aperture () extending transversely to the insertion slot () and opening out into it. A clamping element () for clamping the shaft () can slide in the transverse aperture () and travels into the insertion slot () at one end and protrudes out from the transverse aperture () at the other end. A centering piece () has a rotatable clamping sleeve () equipped with a clamping curve () that slides the clamping element (), equipped with a clamping spring, which engages the clamping sleeve () and rotates the clamping sleeve (). The centering piece () has two transverse apertures () and in which two clamping elements () are supported opposite each other in a movable fashion.

Hand-held jigsaw with clamping device for reciprocating tool, in particular a jigsaw blade

The invention relates to a clamping device () for connecting a saw blade () to a reciprocating rod () of a jig saw, in particular a hand-operated compass saw (), comprising a mounting (), which is connected to the reciprocating rod () and has a recess () for receiving a head end () of the saw blade (), a locking sleeve (), which can be turned about the axis () with respect to the mounting () against the force of a torsion spring () to lock the head end () of the saw blade () in a locking position in the recess () and to allow removal of the saw blade () in a removal position. It is intended that a stop () interacts with a part () of the torsion spring (), in order to prevent movement of the locking sleeve () beyond the removal position.

Clamping device for a jigsaw

A hand-guided power reciprocating saw has a machine housing, a saw blade drivable by a motor into a stroke motion, a guide device having two guide elements resting against the saw blade at opposite sides of the saw blade and operative for guiding and supporting the saw blade crosswise to a sawing direction, the guiding device further having a two-armed pivot lever with lever arms on each of which a corresponding one of the guide elements is situated, the guiding device also having an adjusting mechanism for adjusting a transverse spacing between the guide elements, a holder in which the guide device is integrated and which is configured to be mounted in the machine housing and/or to a base plate attached to the machine housing, the pivot lever being pivotally supported on the holder and the adjusting mechanism being accommodated in the holder.

Hand-guided power reciprocating saw

A hand-held jigsaw machine includes a machine housing (), a saw blade () that is drivable in a reciprocating manner by a motor, a support device () with a support roller () that supports the saw blade on its back (), and a holder () that is fixed to the machine housing () and accommodates the support roller () between two arms (), and a guide device () for guiding and supporting the saw blade () transversely to the saw direction with guide elements () on opposite sides of the saw blade () at an adjustable distance from each other. To ensure economical production of the support and guide device and to reduce the number of components required, the guide device () is integrated in the holder () of the support device ().

Jigsaw machine

A clamping device for toolless clamping of saw blades equipped with the clamping shank for a hand machine tool has two clamping parts that are pressable against each other. Each of the clamping parts is provided with a support surface for the clamping shank of a saw blade insertable between the clamping parts. At least one of the clamping parts is movable in relation to the other of the clamping parts in order to clamp and release the clamping shank. An independent actuating element is movable by hand and provides a sliding movement or a rotating movement.

Clamping device for toolless clamping of a saw blade

A universal saw capable of being employed as a jigsaw or sabre saw, having a housing containing a drive train that includes an electric drive motor and a motion converter that converts the rotary motion of the drive motor into a reciprocating working motion of the saw blade movably guided in the housing, and having a wear-resistant base plate for supporting the universal saw on the work piece to be machined can be adapted with particular ease to the optimally desired intended use as a jigsaw or as a sabre saw in that on the one hand, the base plate () can be rigidly locked in a definite, first operating position in relation to the housing of the universal saw () in which position, the direction of the working movement of the saw blade () is perpendicular to the plane of the base plate () and on the other hand, outside of this operating position, the base plate () can be variably adjusted in its angular position in relation to the direction of the working movement.

Universal saw

A reciprocating hand saw (), having a motor housing () and a gearbox () that receive a battery-operated direct-current motor () with a motor shaft having a shaft end () and a gear (), respectively, which gear&#x2014;as known per se in reciprocating saws&#x2014;is connected to the shaft end in a way driven to rotate and whose gear input pinion () converts the rotation of the motor shaft end () into an up-and-down motion of a push rod () that carries a sawblade (), can be produced economically and is especially sturdy because the gear () and its gearbox () originate in a reciprocating saw that can be operated by alternating current, and because between the shaft end () and the gear input pinion (), a multi-stage coupling (), disposed in a manner fixed against relative rotation for transmitting torque, comprises parts that can be easily separated from one another.

Hand-held saber saw

A reciprocating hand saw with a housing has a motor, a gearbox with a lifting rod for moving a saw blade mounted thereon up and down, and a base plate on which the housing is mounted, capable of carrying particularly easy-to-handle spare saw blades by the fact that the housing has an opening into which a magazine-like, longitudinal saw blade receptacle is capable of being inserted in a detachable, captive manner, and a part of the saw blade receptacle serving as grip projects outwardly.
