The interiors of both sides of the transverse sliding plates 12 are slidably connected to transverse light rods 11. A first rigid spring 14 is provided between the battery compartment 2 and the transverse sliding plate 12, as well as between the two transverse sliding plates 12 and located on the outside of the transverse light rod 11. A transverse moving column 15 is fixed to one end of the transverse sliding plate 12, and the transverse moving column 15 passes through the interior of the battery compartment 2 and is slidably connected to the battery compartment 2. The battery compartment 2 is slidably connected, a rectangular through hole is provided inside the battery compartment 2, the transverse moving column 15 is located inside the rectangular through hole and is slidably connected to the battery compartment 2 through the rectangular through hole, and the setting of the rectangular through hole enables the transverse moving column 15 to slide inside the battery compartment 2, an L-shaped connecting column 5 is fixed on one side of the transverse moving column 15, a rectangular clamping plate 4 is fixed on the top of the L-shaped connecting column 5, the rectangular clamping plate 4 passes through the interior of the battery compartment 2 and is slidably connected to the battery compartment 2, a rectangular limiting groove is provided inside the battery body 3 that is clearance-matched with the rectangular clamping plate 4, and the setting of the rectangular limiting groove enables the rectangular clamping plate 4 to be inserted into the interior of the battery body 3, so that the battery body 3 can be fixed inside the battery compartment 2;
[0027] After the battery body 3 enters the battery compartment 2, due to gravity, the battery base 31 is attached to the lower pressing plate 8, and the vertical moving member 10 is lowered through the vertical connecting plate 9. The lowering of the vertical moving member 10 enables the horizontal sliding plate 12 to slide on the outside of the horizontal light rod 11 through the oblique rotating column 13. Through the arrangement of the horizontal moving column 15 and the L-shaped connecting column 5, the two rectangular clamping plates 4 can move toward the battery body 3, and then the rectangular clamping plates 4 can clamp the battery body 3, so that the battery body 3 can be fixed inside the battery compartment 2;
