The connecting block 272 then moves along the connecting rod 273, and the spring B275 is further compressed until the inner end of the other side of the U-shaped limiting frame 240 no longer pushes out the limiting block 271. Under the action of spring B275, connecting block 272 moves back along connecting rod 273. Connecting block 272 is pushed back, and the inner section of limiting block 271 contacts the inner wall of the other side of U-shaped limiting frame 240 for limiting. Connecting shaft 110 connecting section is inserted into the inner cavity of U-shaped docking frame 220. The operator holds the handle and pulls connecting block 272 to move limiting block 271 out until the inner section of limiting block 271 no longer contacts the inner wall of the other side of U-shaped limiting frame 240 for limiting. After losing the limiting, U-shaped limiting frame 240 is pushed back along guide rod 230 under the action of spring A250. The two extensions of U-shaped limiting frame 240 respectively seal the openings on both sides of the inner cavity of U-shaped docking frame 220. Bolts are inserted into the holes on the two extensions of U-shaped docking frame 220 and the connecting section of connecting shaft 110. One end of the bolt is fitted with a washer and threaded with a nut.
