The through hole 21 of right-hand member is set to hexagon, and correspondingly, outer-hexagonal axle sleeve 32 is the hexagon being engaged with through hole 21, outer when changing
During the fit angle of hexagonal axle sleeve 32 and through hole 21, i.e., can realize that the torsion to spring steel 33 in units of 60 ° is adjusted.
Specifically, when sleeve assembly 3 individually is rotated into 60 ° in contrast to the direction that rotor self-return is rotated, you can
Making the windup-degree of spring steel 33 increases by 60 °；When individually by sleeve assembly 3 towards the side for being same as the rotation of rotor self-return
During to rotating 60 °, you can the windup-degree of spring steel 33 is reduced 60 °.
Further, while turning with carrying out respective angles to connecting hole 12, spring steel 33, through hole 21 and outer-hexagonal axle sleeve 32
When dynamic, can realize that maximum carries out torsion regulation by 150 °, minimum in units of 30 °, can both realize to the torsion of spring steel 33
Quick regulation, it is also possible to realize to the accurate adjustment of the torsion of spring steel 33, it is specific as follows：
It is when the direction that hinge 1 is rotated in contrast to rotor self-return rotates 90 ° and simultaneously that sleeve assembly 3 is opposite
When the direction that rotor self-return is rotated rotates 60 °, you can making the windup-degree of spring steel 33 increases by 150 °；When by hinge
1 direction for being same as the rotation of rotor self-return rotates 90 °, and sleeve assembly 3 is same as into rotor self-return simultaneously
When the direction of rotation rotates 60 °, you can the windup-degree of spring steel 33 is reduced 150 °；Hinge 1 is automatic in contrast to rotor
The direction that return is rotated rotates 90 °, and sleeve assembly 3 is same as 60 ° of the direction rotation of rotor self-return rotation simultaneously
When, you can making the windup-degree of spring steel 33 increases by 30 °；The direction that hinge 1 is same as the rotation of rotor self-return is rotated
90 °, and when sleeve assembly 3 being rotated into 60 ° in contrast to the direction that rotor self-return is rotated simultaneously, you can make spring steel 33
Windup-degree reduces 30 °.
Preferably, the fatigue resistance in order to strengthen spring steel 33, increases automatic resetting device of the present utility model
Service life, spring steel 33 is welded by two flat wires, and is set on the top of spring steel 33 square.
