Referring to fig. 3, in particular, the clamp 6 includes two clamping portions 61 symmetrically disposed on the rotation seat 55, the two clamping portions 61 being located on the same side of the rotation seat 55. The clamping part 61 comprises a first clamping strip 611 and a second clamping strip 612 which are parallel to each other, and the first clamping strip 611 is vertically and fixedly connected with the rotating seat 55; the rotating seat 55 is provided with a chute on one side of the first holding strip 611 along the vertical direction, the chute is positioned above the first holding strip 611, and one end of the second holding strip 612 is inserted into the chute and is arranged in a sliding manner with the rotating seat 55 along the opening direction of the chute. A first elastic piece 613 is fixedly connected between one end of the second holding strip 612 inserted into the sliding groove and the groove wall of the sliding groove close to the first holding strip 611, and the first elastic piece 613 is a spring. When the first elastic member 613 is rested, the interval between the second clamping bar 612 and the first clamping bar 611 is smaller than the thickness of the charging stand 32.

After the gripper 6 moves to the end of the stroke facing the link plate conveyor 10 and the grip portion 61 opens and grips the charging stand 32, the tooth surface front end passes over the gear 1542 and the drive bar 1541 is not separated from the gear 1542. That is, when the clamping portion 61 is opened and the charging seat 32 is clamped from the inside of the transportation frame 11, the tooth surface drives the gear 1542 to rotate to wind the pull rope 152, so that the plug 141 is pulled into the slot, and the charging seat 32 is unlocked. Thereafter, the clamp 6 drives the charging stand 32 to move upwards until the tooth surface is separated from the gear 1542, and the second elastic member 142 rebounds and pushes the plug 141 out of the slot, so as to lock the charging stand 32 subsequently.
