The side push plate 73 is symmetrically and continuously provided with guide rods 72 on both sides. The front end of the guide rod 72 is connected to the side pressure plate 71. Springs 77 are fitted on the guide rods 72 and the rear end of the guide rods 72 between the side push plate 73 and the side pressure plate 71. A soft pad layer 80 is provided on the outside of the side pressure plate 71, and a rough surface 81 is provided on the soft pad layer 80.
[0022] When the side cylinder 75 operates, it drives the side push plate 73 to move on the worktable 2. The side push plate 73 moves via the roller 79. The side push plate 73 drives the side pressure plate 71 and the soft pad layer 80 to clamp the two sides of the assembly frame via the spring 77 at the front end of the guide rod 72. The spring 77 at the rear end is used to buffer the impact force of the side cylinder 75 to avoid excessive impact force from damaging the frame of the assembly. In addition, the soft pad layer 80 has the function of protecting the frame.
[0023] As a further improvement to the above solution, the spring 77 fitted at the rear end of the guide rod 72 is abutted by the retaining ring 78;
[0024] The spring 77 is secured by the retaining ring 78 to prevent it from detaching from the guide rod 72.
