The implementation principle of the embodiment is as follows:

when the lug connection block 2 is installed, an operator rotates the second pull ring 8 at first, the second pull ring 8 drives the corresponding rotating rod 51 to rotate, the second pull ring 8 drives the rotating rod 51 to rotate by one quarter circle, the rotating rod 51 drives the limiting plate 53 to rotate, the position of the limiting plate 53 corresponds to the position of the inner hole of the baffle 61, and the operator keeps the state of the second pull ring 8 unchanged at the moment, even if the torsion spring 71 is always in a deformation state. The operator pulls the first pull ring 43 (can also pull the second pull ring 8), the first pull ring 43 drives the pull plate 41 to move, the pull plate 41 drives the rotating rod 51 to move, the limiting plate 53 is separated from contact with the placing space 62, and the limiting plate 53 moves into the third placing groove 42.

At this time, the operator releases the second tab 8, and the torsion spring 71 promptly returns to the original state. After the operator releases the first pull ring 43, the position of the limiting plate 53 is staggered with the shape and position of the inner hole of the baffle 61, so that the limiting plate 53 cannot enter the placing space 62.

According to the above method, the operator moves the other limiting plate 53 corresponding to the same tab connection block 2 to the same position, and then moves the limiting plate 53.

The operator pulls both first tabs 43 at the same time. The first pull ring 43 drives the pull rod 34 to move, and the pull rod 34 drives the corresponding pressing block 31 to move, so that the corresponding pressing block 31 completely moves into the corresponding second placing groove 32.

The existing positions of the two pressing blocks 31 are guaranteed to be unchanged, and an operator places the lug connection block 2 into the first placing groove 12.

The operator releases the two first pull rings 43, under the action of the elastic restoring force of the springs 35, the springs 35 drive the pull rods 34 to return to the initial positions, the pull rods 34 drive the press blocks 31 to return to the initial positions, and part of the press blocks 31 move into the placing holes 36 on the lug connection blocks 2.

Next, the operator rotates the second pull ring 8, the second pull ring 8 drives the rotating rod 51 to rotate, the rotating rod 51 drives the limiting plate 53 to rotate, after the limiting plate 53 rotates for one quarter of a circle, the position of the limiting plate 53 corresponds to the position of the inner hole of the baffle 61, the operator pushes the pull plate 41 slightly forcefully, the pull plate 41 drives the rotating rod 51 to move, and the rotating rod 51 drives the limiting plate 53 to move, so that the limiting plate 53 moves into the corresponding placing space 62. After the operator releases the second pull ring 8 again, under the elastic force of the torsion spring 71, the rotating rod 51 reversely rotates for a quarter turn, and after the rotating rod 51 drives the limiting plate 53 to rotate for a certain angle, the shape of the inner hole of the limiting plate 53 positioned in the placing space 62 is staggered with that of the inner hole of the baffle 61, so that the limiting plate 53 is prevented from being separated from the placing space 62.

At this time, the positions of the two pressing blocks 31 are fixed, that is, the positions of the tab connection blocks 2 are ensured to be fixed.

The operating personnel are respectively attached to the corresponding tab connecting blocks 2 after bending the tabs with the falling holes on the lithium battery pack, and the operating personnel are connected with the tab connecting blocks 2 through bolts.
