It should be noted that, by adjusting the compression amount of the elastic medium along the length direction of the connecting rod 110 or the sleeve 120, the ratio of the increased pretightening force to the initial pretightening force of the spring device is in a linear relationship, specifically: assuming that the spring device has a series of C and an initial pre-tightening force of F1The maximum stroke is M, the adjustable distance of the adjusting piece 210 is N, and the increasable pretightening force is F2Then, then
After the components in the spring device have been selected, F1And F2The ratio of (2) is only related to the adjustable distance of the adjusting member 210, so that the amount of deformation of the elastic medium is adjusted in the length direction of the connecting rod 110 or the sleeve 120, so that the pre-tightening force of the spring device is linearly changed.
