For example, if the radius r of the pivoting member 142 is 1.5 mm, the maximum value of the rotation angle θ2 of the second body 120 is 180 degrees, which is converted into a radius of 180xπ/180=3.14 (where π is calculated as 3.14), The maximum displacement α _max required for the displacement α2 and displacement α3 is the arc length S. Through the formula S=rxθ1, S=1.5mmx(180xπ/180)=4.71mm can be obtained. This value can still be added according to manufacturing requirements tolerance.
