[0006] The housing of the power output device is also provided with an auxiliary handle, which is arranged above the power output device and perpendicular to the surface direction of the electric tool body. The auxiliary handle is connected to the housing through a clamping ring clamped on the housing.

[0007] The adapter is made of metal, and is protrudingly arranged at the front end of the housing of the power output device. The adapter is provided with a collision protection device.

[0008] The collision protection device is a protective cover arranged at the front end of the adapter. The front end of the adapter is a pressure claw, a card slot is arranged on the pressure claw, and the protective cover passes through the pressure claw and is fixed by a clamping spring.

[0009] The protective cover uses a metal part as the main body, and a rubber layer is provided on the outer layer of the metal part to prevent collision with the processed object during work.

[0010] The technical effect of the utility model is that the auxiliary handle allows the operator to operate the power tool with both hands, making the power tool easier to hold and more accurately positioned. The protective cover can effectively prevent the front end adapter of the power tool from colliding with the working surface, reducing the impact of operating errors on the working surface.
