A second piston 14 is arranged inside the second hydraulic groove 12. The position between the first piston 3 and the second piston 14 is filled with hydraulic oil. The contact position between the first piston 3 and the inside of the first hydraulic groove 2 and the contact position between the second piston 14 and the inside of the second hydraulic groove 12 are both provided with sealing devices to prevent the hydraulic oil from leaking. The side of the second piston 14 away from the bottom of the second hydraulic groove 12 is fixedly connected to the bottom of the second connecting rod 15. One end of the second connecting rod 15 away from the bottom of the second hydraulic groove 12 extends into the inner cavity 10 and is fixedly connected to the bottom surface of the connecting block 16. The top surface of the connecting block 16 is fixedly connected to the bottom of the charging plug 17. The height of the inner cavity 10 is longer than the length of the charging plug 17, so that the charging plug 17 can be received in the inner cavity 10. The top of the charging plug 17 extends through the first through hole 11 to the outside of the charging head 1.
