[0051] See also Figure 5 In some possible embodiments, the elastic element 35 is a cylindrical coil spring, and of course it can also be a conical coil spring, etc., as long as it can provide sufficient elastic preload.
[0052] See also Figures 1 to 5 Since conventional bolt nuts are small, inconvenient to grasp, and laborious to rotate, in order to facilitate the operator to twist, the nut ends of the first fastening screw 22 and the second fastening screw 33 are provided with a rotating block, and the diameter of the rotating block is large, which is convenient for grasping and rotating. The outer circumference of the rotating block can be provided with patterns, convex points, etc. to increase the gripping friction.
