[0031] Furthermore, the hard tube 33 is fixedly connected to the inside of the support base 34 to provide stable support for the support base 34 .

[0032] Furthermore, the inner diameter of the hard tube 33 is larger than the outer diameter of the pull rope 32 , and the pull rope 32 is movably connected to the inner wall of the hard tube 33 , so that the pull rope 32 can move along the trajectory of the inner wall of the hard tube 33 .

[0033] Furthermore, the torsion spring 2 304 is fixedly connected to the inner side of the clamp head 1 31 , and a rotating hole is opened inside the clamp head 2 305 . The clamp head 2 305 is rotatably connected to the outer wall of the plug shaft 2 306 through the opened rotating hole, so that the clamp head 2 305 can change the angle for rotation.

[0034] Example 2, see Figures 1 to 4 On the basis of Example 1, the adjustment mechanism 4 is further obtained, which includes a long plate 41, the long plate 41 is fixedly connected to the inner side of the mounting frame 2, and a spring 42 is sleeved on the outer side of the long plate 41, and one end of the spring 42 is fixedly connected to the limiting sleeve 43.
