The output end of the telescopic cylinder 9 and the movable frame 3 are movably connected through a connecting rod assembly. The telescopic cylinder 9 is used to drive the movable frame 3 to flip, so that the clamping seat 4 flips to the upper side of the battery pack. Then, a plurality of clamping cylinders 6 are used to push the contact seat 7 to move, realizing synchronous fixation of multiple parts of the material, increasing the clamping dead points, and ensuring the clamping stability.

The upper end of the contact seat 7 is fixedly connected to the output end of the clamping cylinder 6. Multiple clamping cylinders 6 can be installed on the two installation plates 5 on both sides, so as to realize synchronous clamping and fixation of both sides of the battery pack. And a plurality of contact seats 7 are pushed by the clamping cylinders 6 to realize clamping of the battery pack, realizing multi-point clamping, forming dead point clamping on both sides of the material, and increasing the stability.

[0026] Please refer to Figure 1 、 Figure 2 and Figure 4 In this embodiment, a connecting seat 91 is fixedly installed on the surface of the fixed end of the telescopic cylinder 9.
