In practice, the diameter of the sealing hole 9011 is smaller than the diameter of the battery case, so that the sealing chamfer 9012 can be pressed on the top edge of the battery case without allowing the top edge of the battery case to enter the sealing hole 9011; the sealing hole 9011 is larger than the outer diameter of the rubber ring, so that the front end of the sealing die 901 can be prevented from touching the rubber ring and crushing the rubber ring.

Further, a positive electrode head accommodating hole 9013 is formed in the bottom of the club head 9042, and the positive electrode head accommodating hole 9013 is a blind hole with an opening at the bottom; the axis of the positive electrode head accommodating hole 9013 coincides with the axis of the club head 9042; the depth of the positive electrode head accommodating hole 9013 is larger than the height of the positive electrode head, and the diameter of the positive electrode head accommodating hole 9013 is larger than the diameter of the positive electrode head.

Because of the existence of the positive electrode head accommodating hole 9013, the positive electrode head of the battery enters the positive electrode head accommodating hole 9013, so that the positive electrode head on the positive electrode cap can be prevented from being contacted with the inner rod 904, the positive electrode head is prevented from being crushed, and the positive electrode head is prevented from being conducted after being contacted with the inner rod 904; meanwhile, when the rubber ring is sleeved at the lower end of the club head 9042, the bottom surface of the rubber ring is flush with the bottom surface of the club head 9042, the positive electrode head enters the positive electrode head accommodating hole 9013, and the rubber ring can be just located on the surface of the positive electrode cap, so that the top edge of the battery shell is convenient to wrap the battery shell.

Further, an insulating head is arranged at the top of the jacking rod 8. Avoiding conduction when the lifting rod 8 contacts with the bottom of the battery.
