Abstract
A kind of puncture needle, including sleeve and needle core, needle core are structure when using across sleeve, it is characterised in that: needle core is no cap structure.The connectionless cap of its needle core, operation Shi Xianyong needle core positioning, then places sleeve, thus is avoided that heavy when puncture needle punctures together with sleeve, the problems such as employment is helped.
Description
Technical field
The present invention relates to a kind of puncture needle more particularly to a kind of puncture needles of the connectionless cap of needle core.
Background technique
Previous puncture needle needle core is all to first pass through attachment cap on needle core and sleeve fine jade is twisted and fixed, then puncture needle with
Sleeve punctures together, will result in equipment integrally heavy problem in this way, and need employment to help always.
Summary of the invention
Goal of the invention
The present invention provides a kind of puncture needle, the problems of previous the purpose is to solve.
Technical solution:
A kind of puncture needle, including sleeve and needle core, needle core are structure when using across sleeve, it is characterised in that: needle core
For no cap structure.
The cavity for accommodating needle core fixed structure is provided in needle core, the needle core fixed structure in cavity includes that setting exists
The top spring of cavity bottom and the fixation branch connecting with top spring, the fixation branch include upright bar and the activity point that upright bar two sides are arranged in
Branch, movable branch include upper movable branch and lower movable branch, and lower activity branch is the left and right two to be linked together by torsional spring
The front end of branch, left and right two is put in the through-hole of needle core side wall, in the case where the inner wall position corresponding with through-hole of sleeve is provided with confession
The fixing groove that two stem cutting of left and right of movable branch enters；The direction of the power of torsional spring is to remain that left and right two is separated to two sides, when
Top spring upwards will fixed branch when pushing up to highest point, the left and right two of lower activity branch is stretched out out of through-hole and puts in sleeve lining
In fixing groove.
Upper activity branch links together by the way that shaft is movable, the upper movable branch when fixed branch rises to most vertex
Left and right two is stretched out needle core tops and can be unfolded and be fixed on sleeve top is fixed temporarily Ka Chu.
Inner wall setting of the fixing groove in same level along sleeve is multiple.
Advantageous effect:
Then a kind of puncture needle, the connectionless cap of needle core, operation Shi Xianyong needle core positioning place sleeve, thus are avoided that and wear
It is heavy when pricker punctures together with sleeve, the problems such as employment is helped.
Detailed description of the invention:
Fig. 1 is the structural diagram of the present invention.
Specific embodiment:
The present invention provides a kind of puncture needle, including sleeve 1 and needle core 2, and needle core 2 is structure when using across sleeve 1,
Be characterized in that: needle core 2 is no cap structure.
The cavity 3 for accommodating needle core fixed structure is provided in needle core 2, the needle core fixed structure in cavity 3 includes setting
Set 3 bottom of cavity top spring 4 and with the fixation branch that connect of top spring 4, the fixation branch includes upright bar 5 and setting in upright bar two sides
Movable branch, movable branch includes upper movable branch 6 and lower movable branch 7, and lower activity branch 7 is to be connected to one by torsional spring
The front end of the left and right two risen, left and right two is put in the through-hole 8 of 2 side wall of needle core, corresponding with through-hole 8 in the inner wall of sleeve 1
Position is provided with the fixing groove 9 entered for two stem cutting of left and right of lower movable branch 7；The direction of the power of torsional spring is to remain left and right two
Branch is separated to two sides, when push up spring 4 upwards will fixed branch push up to highest point when, the left and right two of lower activity branch 7 is stretched out of through-hole 8
Out and put in the fixing groove 9 of 1 inner wall of sleeve.
Upper activity branch 6 links together by the way that shaft is movable, the upper movable branch 6 when fixed branch rises to most vertex
Left and right two stretch out 2 top of needle core and can be unfolded and be fixed on 1 top of sleeve is fixed temporarily Ka10Chu.Fixing groove 9 is same
Inner wall setting on one horizontal plane along sleeve 1 is multiple.
Perform the operation Shi Xianyong needle core positioning, then place sleeve, thus be avoided that it is heavy when puncture needle punctures together with sleeve,
The problems such as employment is helped.
And in terms of the connection of needle core and sleeve, after being positioned with needle core, pushes down on movable branch 6 and make activity point
In the whole lower shift-in cavity 3 of branch, then by 1 set of sleeve outside needle core 2, make then to unclamp upper movable branch 6, at this moment, in top spring 4
Under the action of movable branch integrally move up so that the left and right two of lower activity branch 7 is stretched out out of through-hole 8 and is put in sleeve 1
In the fixing groove 9 of wall, because fixing groove 9 is multiple, even if starting accurately find the position of fixing groove 9, then only need
It wants rotational sleeve 1 that can easily find any one fixing groove 9 to be fixed.
