[0034] Working principle and process of a limit rod connecting fork welding assembly:

[0035] When the worker uses the limiting rod body 1, first connect the connecting fork 7 to the item, then rotate and fix the threaded rod 3 into the inner threaded groove 13 of the limiting rod body 1. To ensure a firm fixation, a cube 2 is rotated and installed on the outside of the threaded rod 3, and the second threaded groove 12 inside the cube 2 is rotated and tightened to fix it. To prevent the connecting fork 7 from shaking and causing the body to break, a cylinder 4 is installed on the front side of the threaded rod 3. An inner groove 19 is opened on the outside of the cylinder 4 for installing cube 14 and cube 2 18. Both block 14 and cube 28 have grooves 15 on their inner sides. A column rod 20 is slidably installed inside the groove 15. A hollow fixing body 16 is rotatably installed around the outside of the column rod 20. A support rod 17 is fixed inside the hollow fixing body 16 to achieve the shaking effect. To prevent the shaking amplitude from being too large, we have grooves 10 on the outside of the cylinder 4. Inside the grooves 10, there are slide bodies 11 and 2 slide bodies 11 respectively to restrict the area. Then, the short threaded rod 8 on the rear side of the connecting fork 7 is rotated into the threaded groove 9 of the fixing block 6.
