The storage slots 2 and one side of the semicircular blocks 6 are provided with protective pads. The protective pads can protect the batteries when the batteries move outward in the storage slots 2.

When the battery needs to be fixed, the semicircular block 6 is squeezed by the battery to move the semicircular block 6. The movement of the semicircular block 6 drives the moving column 5 to move and compresses the spring 7. The spring 7 provides an inward force to the semicircular block 6, so that the two semicircular blocks 6 squeeze and fix the battery, thereby fixing the battery.

When a short-circuit test is required for the battery, the motor 14 drives the screw rod 11 fixedly connected to the movable rotating end to rotate, and the rotation of the screw rod 11 drives the moving block 12 threadedly connected thereto to move, so that the upper conductive sheet 17 at the telescopic end of the first electric telescopic rod 15 is moved to the top of the battery. The upper conductive sheet 17 can be moved to the battery by moving the telescopic end of the short-circuit tester 25, so as to perform a short-circuit test on the battery.

Specific working principle:

When a short-circuit test is required for the battery, the battery to be short-circuited is placed on the top of the lower conductive sheet 9, so that the battery squeezes the semicircular block 6 and moves. The movement of the semicircular block 6 drives the moving column 5 to move and compresses the spring 7. The spring 7 provides an inward force to the semicircular block 6 by itself, so that the two semicircular blocks 6 squeeze and fix the battery. Then, the starting motor 14 drives the screw rod 11 to rotate. The rotation of the screw rod 11 drives the moving block 12 to move, so that the upper conductive sheet 17 at the telescopic end of the first electric telescopic rod 15 moves to the top of the battery. Then, the telescopic end of the short-circuit tester 25 is used to test the battery. The movement of the upper conductive sheet 17 can be moved onto the battery to perform a short-circuit test on the battery. After the short-circuit tester 25 tests the battery, the test signal is transmitted to the controller 24. The movement of the moving block 12 drives the connecting plate 18 to move, thereby driving the slide plate 21 to move in the slide slot 20, so that the position of the push plate 23 is aligned with the battery. When the tested battery is short-circuited, the second electric telescopic rod 22 works to drive the push plate 23 to move. The push plate 23 moves to move unqualified batteries out of the storage slot 2, and the qualified and unqualified batteries are sorted out, thereby realizing the sorting operation of the lithium batteries.
