The connecting rod can be stably connected to the inner cylinder under the action of the first nut and the second nut, and meanwhile, the second nut has the tendency of abutting against the end part of the inner cylinder under the action of the elastic force of the spring. When the connecting rod is subjected to dragging acting force, the buffer can be effectively formed through the spring.
Compared with the prior art, the buffer type slide rail component can move within a set stroke range due to the fact that the buffer type slide rail component is connected with the drawer and the first limiting pin and the second limiting pin respectively realize limiting when limiting, the operation load of the limiting pins in the limiting process is effectively shared, and the stability is high.
Meanwhile, the limiting structure can be properly buffered under the action of the buffer connecting structure, and the stability of the buffer connecting structure is further improved. In addition, the cover plate covers the position limiting hole of the outer barrel, so the structure is compact, and the practical value is high.
