A plurality of insertion holes cooperating with the fixing pin 14 are opened on the outer wall of the big head of the connecting bolt body 1, and a shift block 15 is fixedly installed on the end of the fixing pin 14. The inner wall of the shift block 15 is connected to the outer wall of the connecting sleeve 13 through a fixing mechanism. The fixing mechanism includes a fixing spring 16 installed on the outer wall of the fixing pin 14, and the two ends of the fixing spring 16 are elastically connected to the outer wall of the connecting sleeve 13 and the inner wall of the shift block 15 respectively.

[0024] An upper push bolt 18 is rotatably installed on the outer wall of the connecting sleeve 13 through a supporting mechanism. The supporting mechanism includes a supporting plate 17 fixedly installed on the outer wall of the connecting sleeve 13. The upper push bolt 18 rotates through the bottom wall of the supporting plate 17 through a thread. The end of the upper push bolt 18 is rotatably connected to an upper top plate 20 through a connecting mechanism.
