At this time, the No. 2 spring 25 will be elastically deformed and contracted after being squeezed by the mounting block 21. Then, the end of the fixing frame 11 can be grasped to rotate the fixing frame 11 above the base 1. When the fixing frame 11 is rotated to the desired angle, the handle 22 is released. At this time, the No. 2 spring 25 in the elastic deformation state will rebound. After the rebound of the No. 2 spring 25, it will drive the limit rod 2 to be clamped in the hole opened in the arc plate 18, thereby completing the clamping of the fixing frame 11 above the base 1.
