[0009] Preferably, the guide block is T-shaped, and the inner surface of the guide groove is adapted to the guide block.

[0010] 1. The beneficial effect of the utility model is that when the valve seat body needs to be welded to the surface of the oil cylinder, it is only necessary to rotate the bearing seat according to the situation of the oil cylinder, and the rotation of the bearing seat drives the connecting tube to rotate, thereby driving the threaded sleeve to rotate. Due to the internal thread design of the threaded sleeve, the threaded rod is driven to move, and the guide block is guided to move in the guide groove, thereby driving the splint to move, so that the splint and the oil cylinder are fitted and fixed. After the splints at the four corners are fixed, the welding operation can be carried out, which replaces the hand-held fixation method, thereby improving the fixing effect and avoiding burns to the palm by high temperature of welding.
