The rotation of the rotating plate 201 is pulled by the traction plate 203, so that the four limiting plates 204 can press and fix the fixed sleeve 103, and the fastening pin 206 can fix the adjusted rotating plate 201.

[0034] In order to make the fixing seat 101 conveniently connected to the connecting shaft, Figure 1-3 As shown, the clamping mechanism 3 includes two movable plates 301, and the two movable plates 301 are respectively arranged at the two ends of the inner wall of the fixed seat 101, and the opposite ends of the two movable plates 301 are fixedly installed with clamping plates 302. The clamping plates 302 are clamped to the outer side of the connecting shaft, so that the fixed seat 101 can be conveniently connected to the connecting shaft.

[0035] In order to keep the rotating plate 201 stable after adjustment, Figure 1-4 As shown, the joint body 1 includes a fixed shaft 105, which is fixedly installed on the top of the mounting rod 102. The inner wall of the fixed shaft 105 is threadedly connected to the outer wall of the fastening pin 206. A fixing hole 202 is opened on the inner wall of the rotating plate 201. The fixing hole 202 is movably sleeved on the outside of the fixed shaft 105. The top of the rotating plate 201 is in contact with the screw head part of the fastening pin 206. The threaded connection between the fastening pin 206 and the fixed shaft 105 can fix the rotating plate 201, so that the adjusted rotating plate 201 remains stable, and then the limiting plate 204 can stably press and fix the fixed sleeve 103.
