[0021] like Figures 1 to 5 As shown, a plurality of inner buckling feet 7 are provided on the lower end surface of the inner buckling ring 5, and the inner buckling feet 7 are evenly surrounded on the lower end surface of the inner buckling feet 7 with the center of the inner buckling ring 5 as the axis. The cross-sectional shape of the inner buckling feet 7 is V-shaped and the V-shaped opening is inward. One end of the V-shaped inner buckling foot 7 is fixedly connected to the lower end surface of the inner buckling ring 5, and the V-shaped tip of the inner buckling foot 7 is in contact with the inner walls of the connecting ring 1 and the connecting ring 2 2 respectively.

[0022] like Figure 5 As shown, the inner diameters of the connecting ring 1 and the connecting ring 2 are both smaller at the bottom and larger at the top.

One end of the internal connecting rib 8 passes through the left end face of connecting rod 1 3 and is placed inside connecting rod 1 3. The other end of the internal connecting rib 8 passes through the right end face of connecting rod 2 4 and is placed inside connecting rod 2 4. The internal connecting rib 8 is fixedly connected to connecting rod 1 3 and connecting rod 2 4 respectively.

[0024] like Figure 1 and Figure 5 As shown, a through hole 9 is provided on the pressure cover 6 , and the position of the through hole 9 is concentric with the inner circle of the connecting ring 1 and the connecting ring 2 2 , respectively.
