The bottom end of the bolt body 1 is fixedly connected to a fixing block 4. The surface of the fixing block 4 is provided with a plurality of slots 5. The surface of the bolt body 1 is threadedly connected to a nut 3.

[0021] A connecting block 6 is fixedly connected to the surface of the nut 3 , a clamping block 8 adapted to the clamping slot 5 is fixedly connected to one end of the L-shaped rod 7 , and a connecting plate 9 is fixedly connected to the other end of the L-shaped rod 7 .

[0022] A clamping groove 10 adapted to the connecting plate 9 is provided at the bottom of the connecting block 6 , and a clamping structure for clamping and fixing the connecting plate 9 when the connecting plate 9 is inserted into the clamping groove 10 is provided inside the connecting block 6 .

[0023] The clamping structure includes a accommodating cavity 11, which is opened on the inner wall surface of the clamping groove 10. The inner cavity of the accommodating cavity 11 is provided with a movable plate 12 that slides in the horizontal direction. A spring 16 is laterally fixedly connected between the outer side surface of the movable plate 12 and the outer side surface of the inner wall of the accommodating cavity 11.
