[0029] In use, first, the lithium battery to be clamped is placed on the top surface of the bottom box 1. The built-in speed reducer 11 of the bottom box 1 is started to work, so that the speed reducer 11 drives the driving gear 12 at the output end to rotate. Since the middle part of the bidirectional screw 2 rotatingly connected with the inner wall surface of the bottom box 1 by the bearing seat is fixed with a driven gear 10, and the driven gear 10 is meshingly connected with the driving gear 12, the driving gear 12 drives the bidirectional screw 2 to rotate through the driving gear 12. With the rotation of the bidirectional screw 2, the two clamping plates 5 located on the top surface of the bottom box 1 move towards or away from each other under the action of the extension part 7 along the surface of the bidirectional screw 2. When the two clamping plates 5 move towards each other, the square protrusion 6 on the surface of the clamping plate 5 first contacts the side surface of the lithium battery, and the square protrusion 6 is compressed into the cavity 8 of the clamping plate 5 to compress the spring 9, so as to realize the clamping and fixing of the lithium battery, and ensure the stability of the lithium battery during processing. When the two clamping plates 5 move away from each other, the two clamping plates 5 are separated from the clamping of the lithium battery, so as to facilitate the discharging of the lithium battery after processing.
