[0041] The fixing frame 5 is connected to the outer wall surface of the first bracket 1;

[0042] The cylinder 6 is fixed on the bottom surface of the fixed frame 5;

[0043] like Figure 3 As shown, a notch 11 is provided in the middle of the first bracket 1, and the position of the notch 11 corresponds to the gap between the two bearing plates 12;

[0044] like Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, one end of the fixing rod 8 is connected to the notch 11;

[0045] The sleeve rod 9 is hollow inside and sleeved on the fixed rod 8. The sleeve rod 9 is located on the bearing plate 12. A pressing block 91 is extended from one end of the sleeve rod 9. A center hole 911 is provided at the center of the pressing block 91. A threaded hole 92 is provided on the sleeve rod 9. A screw is threadedly connected to the threaded hole 92 by a screw rod, so that the sleeve rod 9 and the fixed rod 8 are fixed together.
