[0022] In one embodiment, a second circular plate 804 is fixedly installed on the top of the inner rod 5, a plurality of second circular grooves 808 are provided on the lower surface of the upper connecting plate 3, and the inner wall of the second circular groove 808 is in active contact with the outer side of the second circular plate 804, a first circular plate 803 is fixedly installed on the outer side of the sleeve 6, a plurality of first circular grooves 806 are provided on the upper surface of the lower connecting plate 2, and the inner wall of the first circular groove 806 is in active contact with the outer side of the first circular plate 803, the top end of the spring 7 is fixedly connected to the lower surface of the second circular plate 804, and the other end of the spring 7 is connected to the first circular plate 803. The upper surface of a circular plate 803 is fixedly connected, and a threaded rod 801 is fixedly installed on the bottom end of the inner rod 5. The bottom end of the threaded rod 801 extends to the bottom of the lower connecting plate 2. A nut 805 is provided on the outer threaded sleeve of the threaded rod 801. The upper surface of the nut 805 is in movable contact with the lower surface of the lower connecting plate 2. Rectangular holes 807 are provided on the left and right sides of the lower connecting plate 2 to facilitate the removal of the first circular plate 803 and the second circular plate 804 from between the lower connecting plate 2 and the upper connecting plate 3, and at the same time, the spring 7 is removed from between the lower connecting plate 2 and the upper connecting plate 3.

[0023] In one embodiment, a limiting plate 802 is fixedly mounted on the bottom end of the threaded rod 801 , and the movement of the threaded rod 801 is limited by the limiting plate 802 .

[0024] In one embodiment, the inner wall of the rectangular hole 807 is in movable contact with the outer side of the threaded rod 801 , and the rectangular hole 807 is connected to the first circular groove 806 , so that the threaded rod 801 can be moved out from between the lower connecting plate 2 and the upper connecting plate 3 through the rectangular hole 807 .

[0025] In one embodiment, the outer side of the inner rod 5 is in active contact with the inner wall of the sleeve 6 , and the spring 7 is limited by the inner rod 5 and the sleeve 6 .

[0026] The utility model is in operation: when the spring 7 needs to be removed from between the lower connecting plate 2 and the upper connecting plate 3, the nut 805 is rotated, and the upper surface of the nut 805 is pressed against the lower surface of the lower connecting plate 2. At this time, the nut 805 cannot move. Under the thread cooperation between the nut 805 and the threaded rod 801, the nut 805 is rotated to make the threaded rod 801 move downward. When the threaded rod 801 moves downward, it drives the inner rod 5 to move downward. At the same time, the inner rod 5 drives the second circular plate 804 to move downward. The inner rod 5 moves downward and slides inside the sleeve 6. The second circular plate 804 moves downward and compresses the spring 7, thereby shortening the distance between the second circular plate 804 and the first circular plate 803, so that the second circular plate 804 is separated from the second circular groove 808, and the first circular plate 803 is separated from the first circular groove 806, and the first circular plate 803 and the second circular plate 804 are moved, and the threaded rod 801 is driven to move out from between the lower connecting plate 2 and the upper connecting plate 3 under the action of the rectangular hole 807, and the spring 7 is moved out from between the lower connecting plate 2 and the upper connecting plate 3 for replacement;

[0027] When installing the spring 7, push the threaded rod 801 to make it contact with the inner wall of the rectangular hole 807. At this time, the first circular plate 803 is inserted into the inside of the first circular groove 806. Turn the nut 805 to make the threaded rod 801 move upward. The threaded rod 801 pushes the inner rod 5 to move upward. At the same time, the inner rod 5 drives the second circular plate 804 to move upward and insert it into the inside of the second circular groove 808. The inner rod 5, the sleeve 6 and the spring 7 can be installed between the lower connecting plate 2 and the upper connecting plate 3, which makes it easy to flexibly disassemble and assemble the spring 7 to be replaced, thereby improving the portability during disassembly and assembly.
