[0027] The compression mechanism 2 comprises a connecting block 21, the connecting block 21 is rotationally connected to the top end of the fixed rod 5, a support box 22 is fixedly connected to one side of the connecting block 21, a threaded rod 23 is arranged in the support box 22, a rectangular plate 24 is rotationally connected to the bottom end of the threaded rod 23, a square column 25 is fixedly connected to the bottom of the rectangular plate 24, and a compression plate 26 is fixedly connected to the bottom of the square column 25.

[0028] Further, the top end of the threaded rod 23 is fixedly connected with a hand wheel, and the threaded rod 23 is threadedly connected to the top of the support box 22, so that the threaded rod 23 can be rotated by shaking the hand wheel.

[0029] Further, the rectangular plate 24 is slidingly connected to the inner wall of the support box 22, and the bottom of the pressing plate 26 is provided with anti-skid lines, so that the rectangular plate 24 can be stably limited to move.

[0030] Further, the support box 22 is provided with a through opening at the bottom, and the square column 25 penetrates through the through opening, so that the square column 25 can move through the through opening.

[0031] Embodiment two

[0032] Reference Figures 1 to 4 On the basis of embodiment one, the reinforcing mechanism 4 further comprises a connecting plate 41 fixedly connected to the outer wall of the fixed rod 5, a fixed cylinder 42 fixedly connected inside the connecting plate 41, a spring 43 fixedly connected to the inner wall of the bottom of the fixed cylinder 42, a circular plate 44 fixedly connected to the top end of the spring 43, a connecting shaft 45 fixedly connected to the top of the circular plate 44, a push plate 46 fixedly connected to the top end of the connecting shaft 45, an inner spline 47 fixedly connected to one side of the push plate 46, an outer spline 48 engaged with the inner circle of the inner spline 47, and a support shaft 49 fixedly connected to the inner circle of the outer spline 48.

[0033] Further, the top of the fixed cylinder 42 is provided with a through hole, and the connecting shaft 45 penetrates through the through hole, so that the connecting shaft 45 can move through the through hole.
