In the cavity of driven shell 2122, and the outer wall of stress shell 2121 is bonded with the inner wall of driven shell 2122.Stress shell 2121
Bottom is equipped with groove, which is internally recessed by the outside of stress shell 2121, and unilateral bearing 2123 is set in the groove；From
The bottom of dynamic shell 2122 is equipped with circular through hole, and the axis of the through-hole is overlapped with the axis of first rotating shaft 214.First rotating shaft 214
Through-hole across driven 2122 bottom of shell is fixedly connected with the unilateral bearing 2123 at 2121 bottom groove of stress shell, wherein
First rotating shaft 214 is fixedly connected in through hole with driven shell 2122.2123 meetings of unilateral bearing are positive with stress shell 2121
Rotation, when stress shell 2121 rotates backward, unilateral bearing 2123 will not be with rotating backward, wherein stress shell 2121 is just
It is in situ in impact disappearance back spin reply to the design direction of rotation and stress shell 2121 that rotation direction is unilateral bearing 2123
Direction of rotation.
In this way, can be communicated rotational motion to by unilateral bearing 2123 driven when stress shell 2121 rotates movement
Shell 2122, so that driven shell 2122 rotates together also with stress shell 2121；And stress shell 2121 is when reversely rotating,
Unilateral bearing 2123 will not be reversely rotated with stress shell 2121, so that rotating backward for stress shell 2121 will not be by one-way shaft
It holds 2123 and passes to driven shell 2122, ensure that the consistency of the direction of rotation of driven shell 2122.
After impact disappears, damping spring 213 pushes stress shell 2121 and upper housing 211, so that stress shell 2121 and upper
Shell 211 moves toward one another, and due to the setting of unidirectional screw thread, upper housing 211 does not rotate movement；And stress shell 2121 exists
Under the thrust of damping spring 213, along unidirectional screw thread rotation, upper housing 211 is made to occur to transport in opposite directions relative to stress shell 2121
It is dynamic, so that stress shell 2121 is returned to the relative position originally on upper housing 211；Meanwhile the rotary motion band of stress shell 2121
Dynamic unilateral bearing 2123 rotates, and unilateral bearing 2123 drives first rotating shaft 214 to rotate, and the rotation of first rotating shaft 214 drives driven outer
Shell 2122 rotates, and the rotary motion for realizing stress shell 2121 is transmitted to the movement of driven shell 2122 by unilateral bearing 2123
Transmitting.
The lower case 212 of the present embodiment includes stress shell 2121 and driven shell 2122, and stress shell 2121 passes through unidirectionally
Bearing 2123 drives driven shell 2122 to rotate, and driven shell 2122 drives the rotation of 225 outer end of clockwork spring, by the way that unilateral bearing is arranged
2123, clockwork spring 225 can be promoted to discharge potential energy, while playing the role of protecting clockwork spring 225.
