The two side plates 21 provide a limiting function for the battery 4 in a direction perpendicular to the axis of the lamp cylinder 1. The socket 2 is slidable relative to the lamp cartridge 1, and when the socket is mounted, the socket 2 and the battery 4 loaded thereon are pushed into the lamp cartridge 1 together.

Preferably, the clamp 34 is made of a material having a low hardness, so as to avoid scratching the battery 4. It will be appreciated that the surface of the clamping member 34 has a large friction so that after the clamping member 34 abuts the battery 4, the socket 2 is pushed into the lamp holder 1 by the friction and is not easy to push further.

The second rack gear 33 of the present embodiment includes a rack portion for transmission and a rack carrier. The rack carrier may be a cuboid or a prism. One side of the rack bearing part is connected with the rack part, and the rack bearing part is connected with the inner wall of the lamp barrel 1 in a sliding manner. It will be appreciated that, on the basis of the second rack 33 comprising a rack carrier, the invention may be such that the clamping member 34 is not provided, the abutment of the battery 4 being achieved by the end of the rack carrier.
