Road causes fixator to fail.
Working principle: fixator of the invention includes needle body 1 and lock body, and tapered cavity, tapered cavity are provided in lock body
It is inside provided with the lock body structure 2 for fixing needle body 1, the lock body is formed by connecting by upper shell cover 4 and bottom case 5, and intermediate 3 rotates
It is arranged between the upper shell cover 4 and bottom case 5, lock core 212 in lock body structure 2 and is opened up respectively on the center line of lock nut 211
There is pin hole, and lock nut 211 and lock core 212 are concentric cone-shaped cavity structure, passes through upper shell cover 4 after needle body 1 is passed through product
Pin hole be inserted into lock body structure 2, so that fixator is locked on product.Lock body structure 2 is set to the limited post 511 of bottom case 5
It is interior, lock core 212 and steel ball 213 under the action of elastic component 214 and intermediate 3 in the range of lock core shell 215 and lock nut 211 on
Lower activity, when the insertion lock body structure 2 of needle body 1 is locked, the elastic component 214 of 2 bottom of lock body structure resists lock core 212, will lock
The chimeric steel ball 213 of core 212 pushes up the top to lock nut 211, and the section of the lock nut 211 is gradually reduced, and the needle body 1 is successively worn
Friction self-locking is formed between 213 three of tapered cavity and steel ball after crossing the pin hole of the lock body and lock core 212, steel ball 213 blocks
Firmly the resistance of needle body 1 is greater than the frictional force between lock nut 211 and steel ball 213, pulls outward or/and rotate 213 band of needle body 1 and steel ball
Movable lock core 212 and lock nut 211 are movable together, and steel ball 213 clamps needle body 1, and needle body 1 is firmly locked with lock body structure 2；Pass through rotation
Intermediate 3, the screw inclined plane 311 on intermediate 3 press the sliding part 2121 and drive the lock core 212 and be entrenched in lock core
Steel ball 213 on 212 is separated with tapered cavity, and tapered cavity, steel ball 213 and needle body 1 is made to be detached from friction self-locking, realizes needle body 1
Unlock so that the lock body structure 2 be in unlocked state；Intermediate 3 is reversely rotated, the lock body structure 2 restores lock state.
Embodiment two: embodiment two is basically the same as the first embodiment, the difference is that, behaviour is formed on lock core 212
Make bar, the head of operating stick exposes the lock body to facilitate driving lock core 212 to move, keeps steel ball 213, lock core 212 and needle body 1 de-
From friction self-locking, thus realize that needle body 1 is separated with the lock body structure 2, after removing the pressure for acting on operation club head, bullet
Property part elastic force resetted with movable lock core 212 and the steel ball 213 that is entrenched on lock core 212, so that lock body structure 2 is in locking shape
State.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore: it is all according to
The equivalence changes that structure of the invention, shape, principle are done, should all be covered by within protection scope of the present invention.
