An output shaft of the motor 7 is connected with a lead screw 8 through a coupler 10, and the coupler 10 is an elastic coupler; the piston 4 is connected with the nut 9, the piston rod 5 is provided with a corresponding through hole, and the piston 4 can be sleeved outside the nut 9; the piston rod 5 is a hollow structure, and the lead screw 8 can extend into the piston rod 5.

The nut 9 moves up or down along the screw rod through the positive and negative rotation of the motor 7, so that the piston 4 and the piston rod 5 are driven to move up and down, the power is transmitted to the striking head, and the crust breaking operation of the electrolytic cell is completed.

As shown in fig. 3, since the piston 4 is generally circular in shape, a corresponding guide structure is required to prevent the piston from rotating; the following structure may be specifically adopted: if the guide sleeve 15 is arranged on the piston 4, the corresponding guide strip 16 is fixed in the cylinder body 1, and the guide sleeve 15 and the guide strip 16 are matched to play a guiding role and prevent the rotation of the guide sleeve. Of course, in order to simplify the structure, the piston 4 may be square, and the inner cavity of the cylinder 1 has a corresponding shape, so that the purpose of limiting the rotation of the piston 4 is achieved, and the piston 4 can only move along the axial direction of the cylinder 1.
