The present invention is applicable to the technical field of decoration tools and provides a chisel. The chisel comprises a housing; a first guide device arranged in the housing; and a cam mechanism disposed in the housing, wherein the cam mechanism comprises a first end cam and a second end cam which are fixedly connected together and have cam end faces opposite to each other, a connecting device connected with a power device is arranged on one side, opposite to the cam end face, of the first end cam, and the second end cam is a hollow cam; a hollow portion capable of passing through the second end cam, wherein the hollow portion is in contact with and matches the cam end faces of the two end cams, to drive a driven member for movement of a chisel body.

A hand tool device has a tool spindle and a hammer mechanism which includes a hammer and at least one curve guide driving the hammer at least during a hammer drilling operation. The tool spindle has at least one bearing surface on which the hammer is movably supported in at least one operating state.

A power tool that includes a housing, an electric motor, an input device, a reciprocation drive assembly, a striker, an anvil, and an electronic controller is provided. The electronic controller can control the electric motor based on a state of the input device. The electronic controller can receive a first signal from the input device, the first signal indicating a first constant speed of the electric motor, and, in response to the first signal, set an operational speed of the electric motor to the first constant speed. The electronic controller can further receive a second signal from the input device, the second signal indicating a second constant speed of the electric motor that is greater than the first constant speed, and, in response to the second signal, set the operational speed of the electric motor to the second constant speed.
