Spring 5 is interted.
In conclusion by the mutual cooperation of turn-knob structure 20 and magnetic strength mechanism 21 so that positive magnet ring 214 and cathode arc
Attraction is generated between shape magnetic sheet 222, and there is repulsive force among cathode arc magnetic sheet 222, is generated by attraction and repulsive force
Drawing tension prevent spring in wild effect, and cathode arc magnetic sheet 222 is that staggered being interspersed in compressed spring 5,
Using its mutual faint repulsion, it is too fast when avoiding injection reagent and with blood in quickly liquidating, cause unnecessary injury.
It is as follows that it implements principle: pinhead sleeve 7 being removed, by rotational strain tightening device 2 movable cylinder 201 is existed
Its push rod 202 and buckling frame 213 mutually fasten under the turning effort of patient, are not readily separated both under the action of a, and shrink set
Frame 212 is in rotate and rotate counterclockwise to the other end until positive magnet ring 214 under the rotation forces effect of movable cylinder 201
It is fully exposed, and buckling frame 213 is then received into inside rectangle frame 2101, because right by insulation board 215 between positive magnet ring 214
Claim separation and it be positive magnetic, so using the principle that identical charges repel each other, by the circular space of positive magnet ring 214 there are
Mutually exclusive magnetic field, cathode arc magnetic sheet 222 is installing with compressed spring 5 in interspersed for staggered, and cathode arc magnetic sheet
222 be cathode magnetic attribute, has certain repulsive force each other, annulus 220 is passed through telescopic joint rod by downward extruding force
221 are retracted downwards, and the compressed spring 5 that cathode arc magnetic sheet 222 is carried secretly is in compression shape, and because of cathode arc magnetic sheet
222 have repulsive force each other, and compressed spring 5 is iron dust, can completely be adsorbed by cathode arc magnetic sheet 222, compress bullet
Spring 5 is then in pair of a power by the repulsive force mutual from downward active force and cathode arc magnetic sheet 222
In environment resistant, realize that patient will not cause with blood because injection is too fast in the shape that quickly liquidates when injecting reagent with this, thus
Phenomena such as generation pain or blood vessel are heaved, while being that cathode is magnetic using positive magnet ring 214, it is logical after being exposed in air
The principle that there is a natural attraction between the sexes is crossed, there is certain mutual attractive force between positive magnet ring 214 and in-between cathode arc magnetic sheet 222,
There is row between attraction and two cathode arc magnetic sheets 222 to generate between positive magnet ring 214 and cathode arc magnetic sheet 222
Under the interaction of repulsion, which create drawing tensions, prevent compressed spring 5 from carrying out using and pricking in patient by the drawing tension
During needle its in rock shape or because oneself factor occur it is inelastic, mutually block phenomena such as, so as to cause because of spring reason
So that there is nerve pain, phenomenon in injection.
Problems solved by the invention is the prior art because it is exerts oneself by air bubble compression realization to spring, thus
Realize spring high-pressure injection, but it can generate loss nerve because of high-pressure injection and cause pain phenomenon when injecting fluid, it should
Syringe is the injection of spring mechanical formula, causes blocking to make fixed sensor in inaccurate or fast if then its elasticity of spring is bad
Speed promotes moment to cause reagent and blood in quickly liquidating and lead to patient pain, the present invention pass through above-mentioned component mutual group
It closes, the present invention utilizes the mutual cooperation of the turn-knob structure and magnetic strength mechanism that are equipped with, makes its rotary motion and exposes positive magnet ring
In air, to pass through the mutually exclusive power of same sex magnetic, the two sides for keeping apart it by insulation board are equipped with mutually exclusive
Magnetic field, using part of the stable magnetic field on the inside of it, while because cathode arc magnetic sheet magnetism is negative, just using there is a natural attraction between the sexes
Principle so that cathode arc magnetic sheet has certain adsorption capacity outward, and in repulsion magnetic field inside pressing structure, with this
By drawing tension caused by repulsive force and attraction, carry out stabilizing spring, avoids the occurrence of springback or injection speed is too fast
And lead to patients' neural's pain or damage, using cathode arc magnetic sheet in symmetrical and staggered installation, cross-linking with compression
Spring is connected, so that it in injection process, can be adsorbed by cathode arc magnetic sheet because of spring and have faint reprimand each other
Power is heaved so can avoid injection reagent with blood in quickly liquidating so as to cause blood vessel, seriously can be to phenomena such as rupture.
