Abstract
A power tool includes a housing, an electric motor, a switch, an operating element, a contact rod, a pressing block, and a reset element. The electric motor is disposed in the housing. The switch includes a trigger point for controlling the electric motor to be turned on. The operating element is operated so that the switch is triggered. The contact rod is supported by the housing, where the operating element is capable of pushing the contact rod to move. The pressing block is elastically connected to the contact rod and capable of being driven by the contact rod to push the trigger point. The reset element is connected to the contact rod.
Claims18

- a housing;
- an electric motor disposed in the housing;
- a switch comprising a trigger point for controlling the electric motor to be turned on;
- an operating element to be operated to trigger the switch;
- a contact rod supported by the housing, wherein the operating element pushes the contact rod to move;
- a pressing block elastically connected to the contact rod and driven by the contact rod to push the trigger point;
- and
- a reset element connected to the contact rod;
- wherein the electric motor comprises an electric motor shaft extending along a first axis, the operating element is rotatably connected to the housing, the contact rod and the pressing block are driven by the operating element to move along a first straight line and are reset by the reset element, and the first straight line extends along a radial direction of the first axis.
