A ratcheting tool comprises a drive housing provided with a housing cover and an actuating lever. A drive is arranged in the drive housing, wherein the drive comprises a rotary part with toothing rotatably supported in the drive housing. A connector serves for receiving plug-on or plug-in tools. A locking pawl is pivotally arranged in the drive housing, wherein the locking pawl comprises a toothing which engages the toothing of the rotary part for transmitting torque in one direction of rotation. A switch sets the direction of rotation and the engagement of the toothing of the locking pawl into the toothing of the rotary part. A hinge connection connects the locking pawl to the switch, wherein the switch comprises a switching pin which is rotatably supported in the drive housing.

Ratcheting tool with fine toothing

A torque tool for measuring and/or cut-off tightening of a torque on a workpiece. The torque tool is provided within a housing with a handle. The torque to be measured is transmitted with a rod. A measuring element electronically detects the actual torque. A measure- and control electronics for processing the torque detected in such a way. The electronic measure and control electronics controls a cut-off switch for cutting-off the torque tool.

Torque tool with power amplifier

The invention relates to a torque sensor for calibrating screwing tools such as dynamometric keys or impact screw drivers. A torque sensor for calibrating screwing tools has an inner body defining an axis with respect to which a torque is to be measured. The inner body has a seat for engaugement of a screwing tool to be calibrated. An outer annular body is held stationary. This outer annular body is coaxial with the inner body and is connected therewith through radial webs of a first type and through radial webs of a second type. The first type webs have relatively large widths circumferentially but have relatively small axial dimensions. The second type webs are relatively narrow circumferentially but have relatively large axial dimensions. The torque sensor further comprises torsion measuring elements attached to said first type webs for measuring torsional deformation due to torques exerted on said inner body.

A coupling device includes a polygonal coupling part on one of the parts to be coupled for engaging a complementary polygonal counterpart on another of the parts to be coupled. The polygonal coupling part has outer side faces, a longitudinal bore therein, and a first transverse bore with a ball therein intersecting the longitudinal bore and one of the side faces. An actuating body tapering at first and second ends is guided for longitudinal movement in the longitudinal bore between an extended position wherein the first end moves the ball radially into a locking position and a retracted position permitting inward movement of the ball out of its locking position. A second transverse bore intersecting the longitudinal bore guides a releasing element having a cam surface engaging the second end of the actuating body. The releasing element is movable against the action of a biasing spring to move the actuating body from its extended position to its retracted position.
