[0028] Two connecting rods 8 are fixedly connected to the side inner wall of the positioning block 2, and the outer surfaces of the two connecting rods 8 are rotatably connected to the movable plates 9. The side surfaces of the two movable plates 9 are fixedly connected to the plug blocks 10, and the outer surfaces of the plug blocks 10 are movably connected to the positioning block 2. Two slots 11 are provided on the docking block 3, and the outer surfaces of the two plug blocks 10 are movably connected to the two slots 11 respectively.

[0030] Working principle: when the fork frame connecting plate 1 and the pull rod 4 need to be maintained, the limit ring 7 is pulled upwards so that the movable limit ring 7 can drive the lifting block 6 to move horizontally on the limit rod 5, and at the same time, the movable lifting block 6 will pull the spring 18 on the inner wall of the positioning block 2, so that the spring 18 is in a stretched state, and the movable limit ring 7 can drive the fixed block 17 to move. When the movable fixed block 17 is separated from the fixed groove 16 and does not affect the flipping of the positioning plate 15, the restriction on the positioning plate 15 and the second torsion spring 20 can be released, so that the second torsion spring 20 after the restriction is released can flip and rebound, so that the flipped and rebounded second torsion spring 20 drives the connecting shaft 14 on the connecting block 13 to rotate, so that the rotating connecting The connecting shaft 14 can drive the positioning plate 15 and the fixing groove 16 to flip with the connecting shaft 14 as the central axis, so that the flipped fixing groove 16 no longer corresponds to the fixing block 17, and the flipped positioning plate 15 will no longer affect the downward movement of the limiting ring 7, and then press the limiting ring 7 downward, so that the moving limiting ring 7 can drive the fixing block 17 and the lifting block 6 to move, and the moving lifting block 6 will squeeze the spring 18, so that the spring 18 is in a taut state. When the moving limiting ring 7 is no longer in contact with the movable plate 9, the restriction on the movable plate 9 and the first torsion spring 19 can be released, so that the first torsion spring 19 after the restriction is released can flip and rebound, so that the flipped and rebounded first torsion spring 19 drives the movable plate 9 to connect the rod 8 The central axis is flipped, so that the flipped movable plate 9 can drive the plug block 10 to flip. When the flipped plug block 10 is disengaged from the slot 11 and no longer contacts the positioning block 2, the fixation of the docking block 3 and the pull rod 4 can be released, so that the docking block 3 and the pull rod 4 can be removed from the fork frame connecting plate 1 and the positioning block 2, and then the pull rod 4 is pulled to remove the docking block 3 and the pull rod 4 from the fork frame connecting plate 1 and the positioning block 2, and then the fork frame connecting plate 1 and the pull rod 4 can be separated. When the fork frame connecting plate 1 and the pull rod 4 are separated, the fork frame connecting plate 1 and the pull rod 4 can be maintained separately, and then the pressed limit ring 7 is released, so that the spring 18 is no longer subjected to pressure and rebounds, so that the rebound spring 18 can drive the lifting block 6. The limiting ring 7 and the fixed block 17 move, so that the moving limiting ring 7 can squeeze the movable plate 9 to reset and flip, so that the flipped movable plate 9 can drive the plug block 10 to flip, so that the flipped plug block 10 can be inserted into the positioning block 2. At the same time, the flipped movable plate 9 will drive the first torsion spring 19 to flip and stretch, so that the first torsion spring 19 is in a flipped and pulled state. When the rebound force of the spring 18 itself can no longer drive the limiting ring 7 to move, the limiting ring 7 can always fit with the movable plate 9 to limit the movable plate 9 and the first torsion spring 19, so that the first torsion spring 19 can no longer flip and rebound, and then the movable plate 9 can no longer flip. When the fork frame connecting plate 1 and the pull rod 4 are maintained, the limiting ring 7 is pressed downward.The movable limiting ring 7 drives the lifting block 6 and the fixed block 17 to move while keeping the spring 18 in a tightened state. When the moving limiting ring 7 is no longer in contact with the movable plate 9, the restriction on the movable plate 9 and the first torsion spring 19 is released, so that the first torsion spring 19 flips and rebounds and drives the movable plate 9 and the plug block 10 to flip, so that the flipped plug block 10 can be separated from the positioning block 2, so that the flipped plug block 10 will not affect the connection between the positioning block 2 and the docking block 3, and then the docking block 3 is inserted into the positioning groove 12, so that the plug block 10 can correspond to the slot 11. Then, the limiting ring 7 is pulled upward, so that the movable limiting ring 7 can drive the lifting block 6 and the fixed block 17 to move, and the spring 18 is in a stretched state, and the movable limiting ring 7 will squeeze and push the movable plate 9 to flip back to reset, so that the flipped movable plate 9 can drive the plug block 10 to flip, and when the flipped plug block 10 is inserted into the positioning block 2 and the slot 11, the preliminary connection between the positioning block 2 and the docking block 3 is realized, and at the same time, the flipped movable plate 9 will drive the first torsion spring 19 to flip and stretch, so that the first torsion spring 19 is in a flipped and stretched state, and when the movable fixed block 17 is in a flipped and stretched state, the first torsion spring 19 is in a flipped and stretched state. After the fixed block 17 does not affect the flipping of the positioning plate 15, the positioning plate 15 is flipped in the opposite direction, so that the flipped positioning plate 15 can drive the fixing groove 16 to flip and rotate the connecting shaft 14, so that the rotating connecting shaft 14 can drive the second torsion spring 20 to flip and stretch, and then the second torsion spring 20 is in a flipped and stretched state. When the flipped fixing groove 16 corresponds to the fixing block 17, the pulled limiting ring 7 is released, so that the spring 18 is no longer restricted by the tension and rebounds, and then the rebounding spring 18 can drive the lifting block 6, the limiting ring 7 and the fixing block 17. When the movable fixing block 17 is inserted into the fixing groove 16, the restriction of the limiting ring 7, the first torsion spring 19 and the second torsion spring 20 is completed, so that the second torsion spring 20 can no longer drive the positioning plate 15 to flip, so that the limiting ring 7 can no longer move downward, so that the limiting ring 7 can always fit with the movable plate 9, and then the first torsion spring 19 can no longer drive the movable plate 9 and the plug block 10 to flip, so that the plug block 10 can always be inserted in the slot 11, completing the fixation between the positioning block 2 and the docking block 3, and completing the connection and fixation between the fork frame connecting plate 1 and the pull rod 4.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
