The battery manager 400 is placed between the two lifting mechanisms 530, and the horizontal plate 534 is pushed against the eaves 537 under the pushing of the second spring 532, so that the second vertical plate 531 extends out of the base plate 510 and blocks the battery manager 400.
Since the sharp corners of the two triangular plate-shaped members 321 fixed by the pallet 320 are disposed toward the turntable 210, during the movement of the piston rod of the first piston cylinder, the triangular plate 321 pushes the roller 535 at the second riser 531 of the lifting mechanism 530 to move downwards, so that the connecting arm 539 connected to the roller 535 moves downwards, thereby moving the horizontal plate 534 downward, so that the second vertical plate 531 of the terminal body 3312 facing the test terminal moves downward, since the rollers 535 at the second riser 531 of the other lifting mechanism 530 are not pressed by the corresponding triangular plate 321, the second riser 531 of the other lifting mechanism 530 is kept in the extended state, so that in the process of inserting the terminal body 3312 of the test terminal into the terminal-interfacing part 420 of the battery manager 400, the second riser 531 of the other lifting mechanism 530 blocks the battery manager 400 from moving, so that the terminal body 3312 of the test terminal performs a corresponding test on the battery manager 400. And after the test is finished, in the process that the piston rod of the first piston cylinder is driven to reset, the triangular plate 321 leaves the roller 535, so that the roller 535 can ascend, the transverse plate 534 ascends under the pushing action of the second spring 532, the second vertical plate 531 of one lifting mechanism 530 ascends, when the transverse plate 534 reaches the top of the cavity 536, the baffle eaves 537 blocks the transverse plate 534 to continuously ascend, the second vertical plate 531 of one lifting mechanism 530 keeps extending out of the base plate 510, and the second vertical plate 531 of one lifting mechanism 530 restores the blocking action on the battery manager 400. While the second riser 531 of the other elevating mechanism 530 prevents the battery manager 400 from moving in the width direction of the base plate 510 during the insertion of the terminal body 3312 of the test terminal into the terminal interfacing part 420 of the battery manager 400.
In the present embodiment, the two lifting mechanisms 530 are provided, so that the battery manager 400 is prevented from moving along the width direction of the substrate 510, and particularly, the battery manager 400 is prevented from moving when the terminal body 3312 of the test terminal is inserted into the terminal interface portion 420 of the battery manager 400; and the corresponding second vertical plate 531 is lowered in the process of inserting the terminal body 3312 of the test terminal into the terminal butt-joint part 420 of the battery manager 400, so that the second vertical plate 531 is prevented from interfering with the insertion of the terminal body 3312 into the battery manager 400 to damage the terminal body 3312. Moreover, the corresponding second vertical plate 531 is lifted, the triangular plate 321 is matched with the second vertical plate 531, the second spring 532, the base 533, the transverse plate 534 and the two rollers 535, and a simple mechanical structure is adopted to cooperate, especially the two triangular plate 321 are fixed on the supporting plate 320, so that the triangular plate 321 moves by virtue of the piston rod of the first piston cylinder instead of using an independent driving motor or a pneumatic component, and thus the design difficulty and the assembly difficulty are reduced, even the subsequent maintenance difficulty is reduced, the manufacturing cost of a single clamping device 500 is low, and the manufacturing cost of a plurality of clamping devices 500 on the rotary table 210 is greatly reduced.

The L-shaped arms 526 are not affected by the lifting action of the lifting mechanism 530, and at the same time, the two L-shaped arms 526 of each first vertical plate 524 completely lock the bottom of the battery manager 400 from both ends of the battery manager 400, without interfering with the terminal bodies 3312 of the two detection devices 300 being inserted into the terminal interfacing portions 420 of the battery manager 400 from both sides of the battery manager 400, thereby ensuring a good limiting effect and avoiding interference with the terminal bodies 3312 of the two detection devices 300.
