Between end face and the upper surface of lower support member；After puncture, positioning protective sleeve is promoted to needle point direction, needle point is retracted into fixed
In the protective case of position, when needle point leaves core shift bar top through hole, jump ring is sent out in the presence of the upward support force of lower support member
Raw lateral deviation, jump ring bottom tilt with needle tubing, and the parallel bars groove of through hole and upper strata on the subsurface of jump ring bottom is stuck by needle tubing, makes pin
Pipe forms one with jump ring, and when positioning protective sleeve continues to push away to needle point direction, namely needle tubing pulls down, jump ring bottom is by lower branch
The upward resistance of component is supportted, needle tubing can not be moved with jump ring, and needle tubing is limited in positioning protective sleeve；And when needle tubing pushes up
When, jump ring bottom can not be moved by the downward resistance of upper supporting member, needle tubing with jump ring, and needle tubing is limited at positioning protective sleeve
It is interior, it is achieved thereby that needle point will not both pass from the through hole of positioning protective sleeve lower surface, also will not be from positioning protective sleeve upper surface
Through hole pass, by the way that needle point position is stuck in positioning protective sleeve, avoids needle point exposed, cause unnecessary damage.
Therefore, it has the characteristics that simple in construction, reasonable in design and easy to use.
