The plurality of threaded installation rods 102 are adjacent to each other in pairs. Arc-shaped blocks 103 are slidably sleeved on the outer walls of the four groups of threaded installation rods 102. A threaded connection head 105 is rotatably arranged on one side wall of the limiting plate 104. Under the action of the threaded installation rods 102, the arc-shaped blocks 103 can be limited. Under the mutual cooperation of the limiting plate 104 and the threaded connection head 105, the arc-shaped blocks 103 can be fixed.
