Energy storage torsion spring suit is on spacing post 404, and swivel mount 4 keeps away from first piece 402a and the middle part of second piece 402b and sets up torsional spring overlap joint portion 405, and energy storage torsion spring suit is on spacing post 404 back, and torsional spring overlap joint portion 405 falls between first torsion spring arm 301 and second torsion spring arm 302, and the drive division 202 of driving-disc 2 stretches into in the swivel mount 4, falls between first torsion spring arm 301 and second torsion spring arm 302 simultaneously. Preferably, the driving portion 202 is a driving shifting piece with a sheet structure, the driving shifting piece is in an arc structure, and two sides of the driving portion in the width direction respectively abut against the first torsion spring arm 301 or the second torsion spring arm 302, so that the shifting structural strength of the driving portion 202 to the energy storage torsion spring is ensured.

When the driving disc 2 rotates along a first direction (clockwise), the torsion spring overlapping portion 405 overlaps and limits the second torsion spring arm 302, the driving portion 202 drags the first torsion spring arm 301 to synchronously rotate, at this time, because the first displacement piece 402a abuts against the first limiting piece 500a, the first torsion spring arm 301 and the second torsion spring arm 302 are relatively far away, the driving disc 2 rotates to increase the elastic potential energy of the energy storage spring, after the driving disc 2 presses the first displacement piece 402a and the second limiting piece 500a to pass through a rotation dead point, the rotating base can freely rotate, at this time, the potential energy of the energy storage spring is converted into the kinetic energy of the torsion spring overlapping portion 405 driving the rotating base 4 to rapidly rotate, and gear switching of the rotary switch along the first direction is completed; when the rotary switch performs gear switching in the return direction along the second direction (counterclockwise), the driving disk 2 firstly drives the second torsion spring arm 302 to open along the second direction, the first torsion spring arm 301 is limited by the torsion spring overlapping portion 405, energy storage of the energy storage spring is realized, after the second displacement piece 402b and the second limiting piece 500b pass through the rotation dead point, the energy storage spring releases energy to drive the rotating base 4 to rotate along the second direction (counterclockwise), and gear switching in the return direction of the rotary switch is completed.

Preferably, torsional spring overlap joint portion 405 is for setting up in the torsional spring overlap joint boss of swivel mount 4 internal surface, torsional spring overlap joint boss and the opening 402c that shifts arrange in the radial both ends of swivel mount 4 relatively, energy storage spring is by the butt joint boss in-process of torsional spring, energy storage spring accessible spacing post 404 compresses tightly first piece 402a or the second piece 402b that shifts in the internal face that the swivel mount holds the chamber, thereby guarantee first piece 402a and the first locating part 500a that shifts, or the second shifts the overlap joint structural stability between piece 402b and the second locating part 500b, the security that the gear switches improves.

It should be noted that the overlapping portion 405 of the torsion spring and the displacement opening 402c are located at two ends of the rotation seat 4 in the radial direction, and the preferred structure is that the central plane of the overlapping portion 405 of the torsion spring and the central position of the displacement opening 402c extends along the circumference of the rotation seat 4 and is distributed in an angle of 180 degrees.

The rotating base 4 rotates along a first direction, the first displacement piece 402a is matched with the first limiting piece 500a, the energy released by the energy storage torsion spring drives the rotating base to rotate, and after the first displacement piece buckle surface 422a of the first displacement piece 402a collides with the second limiting piece 500b, the rotating base 4 stops rotating; correspondingly, the rotating base 4 rotates along the second direction, the second displacement member 402b passes through the second limiting member 500b, and the rotating base 4 receives the energy released by the energy storage torsion spring to rotate until the second displacement member buckle surface 422b of the second displacement member 402b collides with the first limiting member 500a, and then the rotating base 4 stops rotating; that is, no matter the rotation of the rotation base 4 is forward or backward, the rotation base 4 can only stop rotating by the impact between the displacement member and the limiting member due to the rotation inertia under the unconstrained condition, so that the impact damage between the displacement member and the limiting member is easily caused, and the safety of switching the switch gear is also affected.

second cover stoppers

101 and 102 are protrudingly arranged on the inner side surface of the cover 1.

In the direction of rotation of the swivel base 4, the stopper 406 has a first stopper end face in contact engagement with the first cover stopper 101, and the stopper 406 has a second stopper end face in contact engagement with the second cover stopper 102.
