[0061] When installing the elastic member 35, the first mounting section 38 of the elastic member 35 can be installed into the first mounting groove 48 first, and then the pressure section 40 can be pressed to increase the distance between the first mounting section 38 and the second mounting section 44, and the second mounting section 44 can be installed into the second mounting groove 50, and then the positioning tongue 60 can be guided by the guide slope 62 into the receiving groove 63 for fixation.

[0064] During installation, the elastic member 35 is installed first, and then the buffer member 9 is placed on the elastic member 35 , and then the fixing bolt 37 is used to connect the elastic member 35 and the buffer member 9 .

Through the buffering effects in all directions, the socket can be better clamped and the socket can be kept from being damaged by the clamping force.

[0066] When the socket needs to be clamped and fixed, the electromagnet 10 is disconnected from the power supply, and the first spring 13 pushes the rotating member 8 to flip, driving the buffer member 9 to flip as well, thereby clamping the socket on the conveyor belt 4.

[0067] The electromagnet 10 is arranged in the second sliding groove 12, but cannot move, and is blocked by the second positioning member 20 and the slide bar 7. A symmetrical power connection post 17 is arranged on the electromagnet 10, and an arc-shaped body 28 is arranged in the second sliding groove 12.

The first end body 77 is kept in contact with the slide 21 to better push the slide 21. The second end body 78 pushes the ejector 15 better.

[0070] When the slide 21 is pushed by the magnetic force of the electromagnet 10, the first spring 13 is compressed, and the second spring 14 is pressed by the pusher 15. The rotating member 8 pushes the pusher 15 to press the second spring 14. The magnetic force of the electromagnet 10 can push the pusher 15 to assist the rotating member 8 in rotating. The slide 21 is kept sliding on the slide rod 7, and the rotating member 8 rotates around the first hinge rod 29.

[0071] When the electromagnet 10 is energized, it pushes the slide 21 to push the first spring 13 to move, compresses the first spring 13, pulls the upper end of the rotating member 8 through the hinge 32, and keeps the rotating member 8 rotating around the first hinge rod 29. At the same time, the electromagnet 10 assists in pushing the pusher 15 to push the lower end of the rotating member 8, and keeps the buffer 9 on the rotating member 8 rotating from the side to the upper end. At this time, the socket can pass through the welding seat mechanism 3 here, and multiple welding robot arms 1 can be set according to actual conditions.

[0072] The slide 21 moves in the direction of F1, and the rotating member 8 rotates in the direction of F2. Fig.21 As shown, M is the maximum diameter of the buffer 9, and N is the maximum diameter of the lower end of the rotating member 8. The diameter of the lower end of the rotating member 8 is smaller than the maximum diameter of the buffer 9, which prevents the rotating member 8 from hitting the socket and enables the buffer 9 to clamp the socket.
