By adding the elastic buffer assembly 200 in the restraint assembly 100, the pressure fluctuations caused by the thickness change of the battery 400 are absorbed, so as to keep the pressure fluctuations of the battery core within a controllable range. At the same time, after the battery 400 is placed, the restraint on the elastic buffer assembly 200 is released by the compression assembly 300, so that the elastic buffer assembly 200 presses the battery 400 tightly, improving the clamping efficiency of the battery 400.
[0046] The specific structure of the restraint assembly 100 will be described below:

When restraining batteries 400 with different numbers and different thicknesses, by adjusting the position of the bottom plate 120, the distance of the elastic buffer pop-up is adjusted, so as to adjust the pressure exerted by the elastic buffer assembly 200 on the battery 400, meeting the restraint pressure requirements of batteries 400 with different thicknesses and different numbers.
[0049] In some embodiments, batteries 400 with different thicknesses correspond to a scale plate, and the positions required for different numbers of batteries 400 are indicated on the scale plate, completing the rapid adjustment of the position of the bottom plate 120.
[0050] In order to facilitate the adjustment of the position of the bottom plate 120, at least one sliding groove 131 is provided on the outer side wall of the connecting column 130; a slider 132 is provided at the matching position of the side wall of the insertion opening 121 and the sliding groove 131; the slider 132 is inserted into the sliding groove 131.
[0051] In some embodiments, at least two guide rods 140 are further disposed between the top plate 110 and the bottom plate 120; one end of the guide rod 140 passes through the elastic buffer assembly 200 and is fixedly disposed on the top plate 110, and the other end passes through the bottom plate 120.

[0054] Among them, in order to prevent the two clamping plates 150 from overlapping, which is not conducive to the placement of the battery 400, in some embodiments, limiting sleeves sleeved on the guide rods 140 are arranged on two adjacent clamping plates 150, and the size of the limiting sleeves is smaller than the thickness of the battery 400, so as not to affect the clamping of the battery 400.

[0058] The working processes of the elastic buffer assembly 200 and the compression assembly 300 are as follows:
[0059] In the initial state, the drive rod 310 is in a contracted state. Pulling the movable plate 210 tightens the compression spring 220.
