405 one end can tilt upward or downward；Under normal condition, the damper lock-out for being set to 405 inner surface of magnetic force clamping block is convex
405b and the inconsistent cooperations of damping projection 404a are played, therefore cannot be relatively rotated (i.e. between wear ring 404 and axle bed 103
Lock-out state), and when 405 one end of magnetic force clamping block is upturned, between damper lock-out protrusion 405b and damping projection 404a
It is detached from, there is no mutually conflict active forces, therefore can relatively rotate between wear ring 404 and axle bed 103 and (unlock shape
State).
Referring to Fig.1 4, pivot pin 104 further includes quill 104a, the outer limiting slot 104b of pivot pin, limits in pivot pin in the present embodiment
Position slot 104c and pivot pin screw thread 104d.Specifically, quill 104a is with hollow sleeve structure, the outer limiting slot of pivot pin
104b is respectively arranged at outside and the inner surface of quill 104a with limiting slot 104c in pivot pin, and pivot pin screw thread 104d is set to
The outermost sides quill 104a.Based on above-mentioned, also there is following matching relationship herein：Wear ring 404 is sheathed on quill 104a
On, the two is locked by coordinating between limiting slot 104b outside limit protrusion 404b and pivot pin, cannot be relatively rotated, next is led
Be embedded in quill 104a to sleeve 403, therebetween by limiting slot 104c in guide and limit protrusion 403b and pivot pin it
Between realize locking, can not relatively rotate；After completing all assembly, briquetting 402a is limited by block 401, passes through gear
The screw thread that 401 inside of block is arranged is realized with the 104d cooperations of pivot pin screw thread.
5 schematic cross-sectional view for showing magnetic force lock set 400 in this implementation referring to Fig.1 realizes locking and unlock
Process substantially：Above-mentioned matching relationship is pressed when completing 400 component of magnetic force lock set, and after being left and right symmetrically arranged, magnetic force locking
Block 405 is located at the top of magnetic force switch block component 402, herein it should be noted that magnetic force clamping block 405 and magnetic force switch block component 402
Magnetic force is carried, and is sequentially distributed opposite with 405 magnetic force of magnetic force clamping block and identical polar magnetic on magnetic force switch block component 402
Power, by the way that the range of polarity magnetic force distribution on magnetic force switch block component 402, the range of control locking and unlock is arranged.Lock-out state
When lower, spring 402d is in normal condition (being not compressed), at this time magnetic force clamping block 405 and about 402 magnetic force switch block component point
Cloth is out-phase magnetic pole, and the two has attraction, therefore damper lock-out protrusion 405b and damping projection 404a phases under magneticaction
It mutually contradicts and realizes locking.Under unlocked state, by the above-mentioned briquetting 402a of Manual press, i.e. compressed spring 402d, magnetic force at this time
Swivel becket 402b is gradually embedded in pilot sleeve 403, and guide pad 402c enters in directive slide track 403a, to magnetic rotation ring
402b, which is directed to, to rotate, due to being sequentially distributed and phase opposite with 405 magnetic force of magnetic force clamping block on magnetic force switch block component 402
The magnetic force of same polarity, when having same pole both to turn to, under repulsion effect, shaft rotation occurs for magnetic force clamping block 405
Dynamic one end is upturned, and damper lock-out protrusion 405b is detached from damping projection 404a, completes unlock.Herein it should be noted that
The symmetrically arranged purpose in the present embodiment both ends is need to press above-mentioned briquetting simultaneously by both ends to realize that unilateral side can not unlock
When 402a, the compression to spring 402d could be realized, can unlock.Therefore between briquetting 402a and magnetic rotation ring 402b
The elastic force for being also provided with screens spring 402e, and meeting spring 402d is more than the elastic force of screens spring 402e, when unilateral side presses,
Screens spring 402e can be compressed, and spring 402d is not compressed, but when both sides simultaneously press when, screens spring 402e not by
Power at this time after the symmetrical spring 402d forced compressions in both ends, realizes unlock.
It should be noted that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to preferable
Embodiment describes the invention in detail, it will be understood by those of ordinary skill in the art that, it can be to the technology of the present invention
Scheme is modified or replaced equivalently, and without departing from the spirit of the technical scheme of the invention and range, should all be covered in this hair
