[0025] The inner surfaces of the two docking boxes 4 are fixedly connected with multiple limit rods 14, and the outer surfaces of the limit rods 14 are slidably connected with T-blocks 15. The limit rods 14 pass through the T-blocks 15, and the corresponding two T-blocks 15 are fixedly connected with the same baffle 16. The outer surface of the limit rod 14 is slidably sleeved with a spring 17, and one end of the spring 17 is fixedly connected to the side surface of the T-block 15. The end of the spring 17 away from the T-block 15 is fixedly connected to the side inner wall of the docking box 4. A T-slot 18 is provided on the docking box 4, and the outer surface of the limit rod 14 is slidably connected to the T-slot 18. The side surface of the baffle 16 contacts the movable plate 11. The number of torsion bar T-blocks 15 is multiple and distributed in a rectangular array, and the number of baffles 16 is multiple and distributed in a rectangular array.

[0026] Working principle: When the torsion bar spring 1 and the first connecting arm 2 need to be disassembled, the baffle 16 is pulled so that the movable baffle 16 can drive the T-block 15 to move horizontally on the limit rod 14. At the same time, the movable T-block 15 will squeeze the spring 17 on the inner wall of the docking box 4, so that the spring 17 is in a taut state. When the movable baffle 16 is no longer in contact with the movable block 10 and the movable plate 11, the fixation of the movable block 10 and the movable plate 11 is released, and then the movable plate 11 is flipped over so that the movable plate 11, the limit block 12 and the movable block 10 are flipped with the connecting rod 9 as the central axis. When the flipped limit block 12 is disengaged from the limit groove 13, the fixation between the torsion bar spring 1 and the first connecting arm 2 is released. , so that the torsion bar spring 1 and the first connecting arm 2 can be separated, and then the docking box 4 is pulled, and the first connecting arm 2 can be removed from the torsion bar spring 1, and then the movable plate 11 is flipped back, so that the flipped movable plate 11 can drive the movable block 10 and the limit slot 13 to flip, and then the pulled baffle 16 is released, so that the spring 17 is no longer restricted by the tension and rebounds, and then the rebound spring 17 can drive the T-block 15 to move back in the T-slot 18, so that the moving T-block 15 can drive the baffle 16 to move back, so that the moved baffle 16 contacts the movable plate 11 again, and when the torsion bar spring 1 and the second connecting arm 3 need to be disassembled, the above operation can be performed again. After the torsion bar spring 1, the first connecting arm 2, and the second connecting arm 3 are separated, different maintenance work can be performed on the torsion bar spring 1, the first connecting arm 2, and the second connecting arm 3. When the maintenance of the torsion bar spring 1, the first connecting arm 2, and the second connecting arm 3 is completed, it is necessary to connect the torsion bar spring 1 with the first connecting arm 2 and the second connecting arm 3. Pull the baffle 16 again so that the moving baffle 16 drives the T-block 15 to move while keeping the spring 17 in a taut state. When the moved baffle 16 is no longer in contact with the movable block 10 and the movable plate 11, flip the movable plate 11 again so that the flipped movable plate 11 can drive the movable block 10 and the limit block 12 to flip. When the limit block 12 is flipped, it will not affect the torsion bar spring 1 and the first After the connection between the connecting arms 2, the torsion bar spring 1 is inserted into the connecting groove 7 on the docking box 4, and the docking block 5 is inserted into the docking groove 6 at the same time. When the docking block 5 is fully inserted into the docking groove 6, the limit ring 8 can be in contact with the docking box 4, and then the movable plate 11 is flipped back, so that the flipped movable plate 11 can drive the movable block 10 and the limit block 12 to flip. When the flipped limit block 12 is inserted into the limit groove 13, the pulled baffle 16 is released, so that the spring 17 is no longer restricted by the tension and rebounds, and then the rebound spring 17 can drive the T-block 15 and the baffle 16 to reset. When the movable baffle 16 contacts the movable plate 11, the fixation of the movable block 10, the movable plate 11 and the limit block 12 is completed.The limiting block 12 will not be separated from the limiting groove 13, thus completing the connection and fixation between the torsion bar spring 1 and the first connecting arm 2. Then, the above operation is repeated to complete the connection between the torsion bar spring 1 and the second connecting arm 3, thereby completing the connection between the torsion bar spring 1 and the first connecting arm 2 and the second connecting arm 3.
