[0028] Specifically: There are three first springs 5 ​​to ensure the stability of the insulating plate 4 and to drive the insulating plate 4 to move. The top of the battery compartment 2 is an opening, which can be closed by a slide plate 7 to facilitate limiting the battery body 6 and removing the battery. The screw holes in the inner cavity of the lower pressing block 11 and the inner cavity of the supporting block 12 can enable the bolts 17 to fix the bottom frame 1 and the top frame 3 together, so as to stabilize the battery compartment 2.

[0029] For example 2, please refer to Figure 1-5 On the basis of the first embodiment, both sides of the insulating plate 4 are fixedly connected with extension blocks 13, and the top of the extension block 13 is movably connected with a roller 14, and the surface of the roller 14 is slidably connected to the bottom of the pull block 8. The top of the bottom frame 1 is fixedly connected with a clamping column 15, and the bottom of the top frame 3 is fixedly connected with a positioning column 16. The surface of the positioning column 16 is slidably connected to the inner cavity of the clamping column 15.
