Cover in 3 inner chambers, the side wall of described safety shield 3 is provided with vertically side by side one is long and the other is short two sections of chutes, the respectively first groove 304
With the second groove 305, described first groove 304 and the second groove 305 pass through one section of skewed slot 306 UNICOM, described cunning towards the front end of needle point
Socket part 201 side wall is provided with the projection 203 with described first groove 304 and the cooperation of the second groove 305 gap, and described projection 203 coordinates
First groove 304 and the second groove 305 slide, described projection 203 original state coordinates in the second groove 305, during use,
Slide to the first groove 304 from the second groove 305 through skewed slot 306.The side wall near front end for the described slide connecting part 201 is provided with and circumferentially sets
The draw-in groove 204 put, described projection 203 coordinates under state in the first groove 304, and described draw-in groove 204 is right vertically with through groove portion 303
Together, when described projection 203 is in the first groove 304 tail end, described needle tubing 1 is completely disposed in safety shield 3 inner chamber, described projection
203 when being in the second groove 305 tail end, and the needle point of described needle tubing 1 is in the end of safety shield 3, in described safety shield 3 inner chamber
It is additionally provided with the back-moving spring 5 of compression spring composition, one end of described back-moving spring 5 is against safety shield 3 inner chamber front inner wall, separately
One end is against on described slide connecting part 201, is preferably provided with annular cavity 205, described back-moving spring in described slide connecting part 201 front end face
5 one end are placed in annular cavity 205 so that safety shield 3 has an elastic force forward all the time.Described safety shield 3 He
The position of the length of slide connecting part 201 and groove 302 and draw-in groove 204 is suitable, that is, when described projection 203 is in the second groove 305
During tail end, the needle point of described needle tubing 1 is in the end of safety shield 3 (preferably needle point slightly exposes a bit), described safety shield 3
Tail end need to leave certain glade plane space to cap for brush portion 202, this clearance distance and the second groove 305 similar length or equal, and
Enable described needle tubing 1 to expose enough length from safety shield 3 front end, complete to inject；And work as described projection 203 and be in
During one groove 304 tail end, the length of safety shield 3 enables to described needle tubing 1 and is completely disposed in safety shield 3 inner chamber.
So that in use, described projection 203 can successfully slide to the first groove 304 from the second groove 305, this
In specific embodiment, described second groove 305 is arranged in inclined-plane 307 near the position side wall with the first groove 304 UNICOM, described projection
203 sides corresponding thereto are equally also arranged for direction identical inclined-plane 307.
So that safety shield 3 is more uniformly stressed in use, reliable operation, in the side wall of safety shield 3
On can be uniformly distributed more than one group of the first groove 304 of setting and the second groove 305 and draw-in groove 204, projection 203, this is specifically real
Apply in example, the side wall of described safety shield 3 is provided with two group of first groove 304 and the second groove 305, two composition axial symmetry settings；Institute
Stating groove 302 is circumferentially arranged annular groove 302, is provided with a pair of through groove portion 303, described through groove portion in described groove 302
303 is circumferentially symmetrical, and the side wall near front end for the described slide connecting part 201 is provided with draw-in groove 204 described in a pair, described a pair
Draw-in groove 204 is circumferentially symmetrical；Described slide connecting part 201 side wall is provided with a pair of projection 203,203 one-tenth axial symmetry of a pair of projection
Setting.
As using front protective measure, preferably outside described needle stand 2 and safety shield 3, also it is arranged with oversheath 6, outer shield
Set 6 is tubular, and front end is closed, and open rearward end becomes interference fit or screw thread cooperation with cap for brush portion 202 outer wall, is formed and detachably connects
Connect, unloaded during use.
The operation principle of safety novopen supporting use pin is as follows:
During original state, as shown in Figure 1, 2, under the elastic force of back-moving spring 5 acts on, described projection 203 is in the second groove
305 tail ends, safety shield 3 forward slip is limited, and the needle point of described needle tubing 1 is in the end of safety shield 3.During use, such as
Fig. 3, shown in 4, supporting for safe novopen being threaded connection with pin is arranged on safe novopen front end, by needle point pair
Quasi- injection site carries out pushing acupuncture treatment, and thrust overcomes the elastic force of back-moving spring 5 so that safety shield 3 is along described needle stand 2
Slide connecting part 201 retreats, and in this fallback procedures, needle point gradually stretches out, and projection 203 forward and passes through tiltedly along the second groove 305
Groove 306 slides to the first groove 304 front end, and needle point stretches out to put in place to be injected, sliding along the skewed slot 306 of the second groove 305 in projection 203
To the first groove 304, in the presence of inclined-plane 306, safety shield 3 is rotated against with the slide connecting part 201 of needle stand 2,
Axially alignd with draw-in groove 204 in the through groove portion 303 in described groove 302；After the completion of injection, pushing force eliminates, in reset bullet
Under the elastic force effect of spring 5, described projection 203 is in the first groove 304 tail end, and the elastic collar 4 in described groove 302 is certainly simultaneously
Expose from through groove portion 303 under body elastic reaction and be embedded in draw-in groove 204, prevent safety shield 3 from skidding off from needle stand 2, by described pin
Pipe 1 covers in safety shield 3 inner chamber completely, as shown in Figure 5,6, thus avoiding accidentally injuring, reduces the risk of cross infection.
