[0033] When the bidirectional threaded rod 5 rotates, due to the transmission effect of the thread, the adjusting column 3 and the adjusting column 4 will move to the upper and lower sides or the direction of approaching each other according to the rotation direction of the bidirectional threaded rod 5. The outside of the bidirectional threaded rod 5 is fixedly connected with an anti-skid sleeve 6, the anti-skid sleeve 6 is made of rubber material and has dense raised lines on the surface, so as to increase the friction between the hands of the operator and the bidirectional threaded rod 5, facilitate holding and rotating the bidirectional threaded rod 5, and realize the adjustment of the positions of the adjusting column 3 and the adjusting column 4.

[0034] The upper and lower ends of the bidirectional threaded rod 5 are fixedly connected with a tension rope 7, the inside of the adjusting column 3 and the adjusting column 4 is provided with an adjusting assembly, the adjusting assembly can adjust the positions of the adjusting column 3 and the adjusting column 4, the adjusting assembly comprises a connecting sleeve 8, the inside of the connecting sleeve 8 is fixedly connected with a spring 9, the outside of the tension rope 7 is slidably connected to a through hole on one side of the connecting sleeve 8, and the outside of the tension rope 7 is slidably connected to the inner wall of the connecting sleeve 8; the diameter of the through hole is slightly larger than the outer diameter of the tension rope 7, so that the tension rope 7 can freely slide and cannot shake too much.

[0035] The other end of the spring 9 is fixedly connected with a limiting plate 10. When the bidirectional threaded rod 5 rotates, the tension rope 7 can smoothly slide in the adapter sleeve 8, thereby driving the spring 9 and the limiting plate 10 to move. The limiting plate 10, which is fixedly connected to the side of the tension rope 7 away from the bidirectional threaded rod 5, exerts a pulling force or a pressure on the spring 9 through the limiting plate 10 when the tension rope 7 moves with the rotation of the bidirectional threaded rod 5, so that the spring 9 is deformed by stretching or compression.
