It is noted that the thrust is linear with the distance the load bar 1 moves towards the adjustment nut 6. Specifically, the pushing force is 1N, and the distance that the load lever 1 moves toward the adjusting nut 6 is 1 mm. When the load rod 1 moves away from the adjusting nut 6, the small-diameter load rod 1 drives the adjusting bush 5 to push the right spring seat 4 to compress the spring 2, so that the spring 2 is pressed to generate a pulling force, and the pulling force faces away from the adjusting nut 6. It is noted that the pulling force is linear with the distance the load bar 1 is moved away from the adjustment nut 6. Specifically, the pulling force is 1N, and the distance of the load rod 1 moving back to the adjusting nut 6 is 1 mm.
