[0020] A fastening rod 5 is movably provided in the fixing plate 6, and a stopper 15 for support is symmetrically provided on the outer wall at the top of the fastening rod 5. The stopper 15 is located on the surface of the fixing plate 6, and can support the outer wall of the fastening rod 5 to prevent the fastening rod 5 from falling off in the fixing plate 6. A matching fastening sleeve 9 is threadedly connected to the outer wall of the bottom end of the fastening rod 5. The fastening sleeve 9 is located at the bottom of the fixing plate 6. A number of connecting rods are fixed to the outer wall of the fastening sleeve 9 at equal intervals along the circumferential direction. The connecting rod is adjusted to drive the fastening sleeve 9 to rotate so that it can be close to the bottom of the fixing plate 6, thereby fixing the fastening rod 5.

[0021] like Figure 3 As shown, the outer wall of the fastening rod 5 is symmetrically provided with a reset slot 11, and the block 15 can be received inside the reset slot 11. The reset slot 11 is internally slidably connected with a matching connector 16. One end of the block 15 is rotatably connected to the connector 16 for easy operation and opening. A reset spring 17 for support is connected between the connector 16 and the inner wall of the reset slot 11, which can be elastically raised and lowered to adapt to different fixed distances.

[0022] A movable hole 14 is provided inside the fastening rod 5, and a threaded rod 13 is connected to the internal thread of the movable hole 14. The top end of the threaded rod 13 extends to the outside of the fastening rod 5 and is fixed with an anti-slip block 4.
