(1) When F2 is smaller than F3, C0 is larger than C, the spring pre-tightening core component is not in effective contact with the limiting shell, the circumferential rotation of the limiting shell is too flexible, and the thickness C of the adjusting pad is required to be moderately reduced by a grinding method;
(2) When F2 is greater than F3, C0 is greater than C, the spring pre-tightening core component is further extruded by the limiting shell, the spring pre-tightening force is increased, the limiting shell cannot rotate, but the spring pre-tightening core component is easier to rotate, and the rod component needs to be disassembled and adjusted;
(3) When F2 and F3 are close, c0=c, the ideal state of adjustment, at this time, the spring pretension core assembly is harder to rotate, and the limiting shell has a certain degree of freedom of rotation.
