it should be noted that the diameter of the round hole is slightly larger than the outer diameter of the rod head cylinder, so that the rod head cylinder can easily pass through the round hole to keep the bottom part in contact with the bottom support 4 when being loaded, and the rod head cylinder can adapt to the rod head cylinder product with small size in a small range;

of course, the diameter of the circular hole is slightly larger than the outer diameter of the rod head cylinder, so that the rod head cylinder may not be in a completely vertical state in the process of driving the rod head cylinder to rise through the bottom support 4, but after the top of the rod head cylinder touches the stop part 17, the bottom support 4 continuously moves upwards, and the rod head cylinder can be centered and fixed by using the clamping force of the upper end and the lower end.

A movable top limiting component is arranged above the bottom supporting structure, and the top limiting component is matched with the bottom supporting structure to clamp and fix two ends of the rod head oil cylinder;

in addition, in the invention, after the processing of the club head cylinder is finished, the drive structure works reversely to drive the bottom supporting structure to descend and the sleeve shaft 15 to rotate reversely, and in the initial stage of the descending of the bottom supporting structure, because the torsion spring 18 between the sleeve shaft 15 and the deflection shaft 16 is still in a twisted state, the torsion spring 18 has power storage, the stop part 17 cannot deflect reversely, and the sleeve shaft 15 drives the stop part 17 to deflect reversely only when the torsion spring 18 is restored to a natural state, so that the problem that the stop part 17 deflects reversely to abrade the top of the club head cylinder when the bottom supporting structure begins to descend is avoided.

Specifically, one convex column is fixed on the stop member 17, another convex column is fixed on the side wall of the sleeve shaft 15, the torsion spring 18 is sleeved on the deflection shaft 16, and two ends of the torsion spring 18 are respectively sleeved on the two convex columns;
