摘要： Disclosed is a machine tool having a spindle driven by a drive device, the spindle having a receiving device on its free end for a tool or a tool holder, an input part being provided in the drive train of the drive device, the input part transferring a torque having a defined play in the direction of rotation via drivers to an output part which is joined in a rotationally fixed manner to the spindle, while a torque acting from the spindle in the direction of the drive device and exceeding a torque on the input side is supported on the housing of the machine tool via clamping surfaces on the periphery of the output part, via clamping elements and via a locking ring having a hollow cylindrical surface. The output part is a driving profile having two or more axially parallel planes, of which a first part acts as clamping surfaces and a second part acts as driving surfaces which cooperate with the drivers of the input part.

摘要： A switchable gear in a handheld power tool has at least two gear stages which are to be engaged via an adjustable switching member, the switching member being in a latched position via a retaining element fixedly held against a housing in a first gear stage. Furthermore, a spindle for receiving a tool may be driven via an axially spring-loaded gear wheel, the gear wheel being axially supported on the retaining element on the side opposite the switching member.
