[0011] Furthermore: a nut fixing frame is arranged in the handle housing, a mounting bolt is arranged on the nut fixing frame, and the nut is threadedly connected to the mounting bolt.

[0012] Further: the inner diameter of the nut is divided into a first mounting part and a second mounting part, the diameter of the first mounting part is smaller than the diameter of the second mounting part; the mounting bolt is threadedly connected to the first mounting part, and the screw is threadedly connected to the second mounting part.

[0013] Further: a recessed groove is arranged on the battery cover around the through hole, and the clamping cap includes a circular plate and a vertical plate.

[0014] Furthermore: a washer is also provided on the end face of the nut, and a spring is provided on the washer.

[0015] The beneficial effects are:

[0016] During the specific installation, first insert the card block of the battery cover into the card slot of the handle shell to avoid friction with the shell; then manually tighten the hand screw and tighten the screw into the nut. At this time, the battery cover will be pressed onto the handle shell by the compression cap on the screw to fix the battery.

[0017] This structure uses only one screw, which is easy to disassemble, and the snap-on method of the buckle assembly can avoid friction between the handle shell and the battery cover, thereby increasing the service life of the device. BRIEF DESCRIPTION OF THE DRAWINGS
