Field: Machine tools (Mechanical engineering)
Classification: CPC B | IPC B

Claim 11:
12. A power tool, comprising:
a casing;
an output mechanism disposed at a front end of the casing;
a motor configured to provide power for the output mechanism;
a leadscrew extending along a front-and-back direction and connected to the output mechanism;
a rotation assembly connected to the motor and driven by the motor to rotate around the leadscrew;
a radial transmission assembly driven by the rotation assembly to rotate;
an axial transmission assembly separately connected to the radial transmission assembly and the leadscrew in a rotation manner and configured to drive the leadscrew to move along an axial direction of the leadscrew; and
a torque transmission portion disposed between the radial transmission assembly and the axial transmission assembly and configured to transmit torque and cause the axial transmission assembly and the radial transmission assembly to rotate synchronously,
wherein the output mechanism comprises a container and a piston movable in the container, the power tool further comprises an anti-failure mechanism detachably connected to the piston, the anti-failure mechanism comprises a cleaning tooth, and, in a case where the anti-failure mechanism moves relative to the leadscrew, the cleaning tooth removes a residual adhesive on the leadscrew.
