Therefore, the two support rings can support the interface, cable and other positions. At the same time, a cavity is opened in the support ring. Reinforcing components are evenly distributed in a ring in the cavity. The reinforcing components are fixed by two cross rods, thereby improving the deformation resistance of the support ring.

Then, the upper and lower positions inside the side of the connecting sleeve are provided with connection holes. After inserting the second pin into one adjustment hole and the connection hole, the position is locked with a nut. This improves the adjustment capability between the connecting rod and the connecting sleeve during operation.

[0016] (3) During assembly, the insert rod is inserted into the inside of the mounting sleeve, and then the first locking pin is inserted to complete the connection assembly between the mounting sleeve and the insert rod. After the first locking pin is inserted, the position is locked with a locking nut, which improves the convenience of assembly. At the same time, the first connecting plate can be fixed to the front end face of the support ring with bolts at the position of the first connecting plate. The second connecting plate is fixed to the front end face of the connecting sleeve. The second connecting plate can be connected and assembled with other connecting surfaces such as the instrument surface and the mounting base surface, thereby improving the overall assembly capability during the operation.
