Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.
This utility model is achieved in that as depicted in figs. 1 and 2 the microscopic needle carrier includes can by axle fitting 5
One end structure of the first caliper 1 being rotatably connected and the second caliper 2, the first caliper 1 and the second caliper 2 near axle fitting 5
Into needle forceps mouth, the other end is respectively connected with the needle forceps mouth that causes of cooperation and keeps the elastic component 8 of open configuration, and elastic component 8 can be with
Caliper consolidation is for an entirety or is removably disposed between the first caliper 1 and the second caliper 2；Structure of the present utility model
It is improved by, between first caliper 1 and the second caliper 2, is provided with the lock group for being kept closed needle forceps mouth
Part, is additionally provided with the first caliper 1 and the second caliper 2 between latch components and elastic component 8 and hinders the spacing of latch components disengaging
Component；In the specific implementation, first caliper 1 and the second caliper 2 can be relatively rotated along axle fitting 5, and axle fitting 5 can be pin
Axle or screw etc., with the relative rotation of the first caliper 1 and the second caliper 2, needle forceps mouth is opened or is closed；
Due to the mutual elastic force effect of the elastic component 8 of 2 end of the first caliper 1 and the second caliper so that the first caliper 1 and the
Two calipers 2 keep maximum opening angle when not acted on by external force, and now needle forceps mouth is in open configuration, regulation elasticity part 8
Parameter, the angle that needle forceps mouth opens can be changed, the elastic component 8 can adopt arc spring lamination or spring etc.；
When the first caliper 1 and the second caliper 2 are subject to external force to act on, its angle constantly reduces, and now needle forceps mouth is continuous
Closure, when the first caliper 1 and close enough the second caliper 2, needle forceps mouth is closed completely, and is located at the first caliper 1 and second
Latch components padlock on caliper 2 is to together so that overcome 8 bullet of elastic component with one between the first caliper 1 and the second caliper 2
The pulling force of power, now needle forceps mouth will maintain closure state always, the latch components can be using buckle and draw-in groove and hook
The structure of button and hook and slot, and under the action that the first caliper 1 and the second caliper 2 further reduce angle, the latch components can
With the action that disengaging is attached to from padlock；
When the first caliper 1 and the second caliper 2 are in the presence of external force, when its angle further reduces, external force now is not
Only need to overcome 8 elastic force of elastic component, in addition it is also necessary to overcome the effect of the limit assembly between the first caliper 1 and the second caliper 2
Power, user only increase active force and the first caliper 1 and the second caliper 2 could be caused to reduce angle, apply on less stroke
Plus bigger active force departs from just can latch components unblock, to improve the structural reliability and control feel of needle forceps；It is described
Limit assembly is to be applied to the first caliper 1 and the second caliper 2 during latch components depart to hinder which to reduce the work of angle
Firmly, it can be using shell fragment, spring and other elastic partss etc..
The key component that this utility model is related to includes limit assembly and latch components etc., and its concrete structure can be according to reality
Needs are configured, and are preferably embodied as structure as follows：As shown in Figure 4 and Figure 5, the limit assembly includes being separately positioned on
The first locating part 6 and the second locating part 7 on first caliper 1 and the second caliper 2, first locating part 6 and the second locating part 7
There is before disengaging the elastic force for hindering that the first caliper 1 and the second caliper 2 are close in latch components；First locating part 6 is bullet
Reed or spring wire, second locating part 7 are position-limitting pin；Its course of work also as shown in Figure 4 and Figure 5, works as latch components
When being locked to together, the first locating part 6 and the second locating part 7 and not in contact with, that is, during latch components are sealed, external force
Only need to the closure for overcoming the elastic force of elastic component 8 to be capable of achieving needle forceps mouth；When unblock is needed, bowl external force is further applied to
2 active force of first caliper 1 and the second caliper, now the first locating part 6 and the second locating part 7 contact, produce hinder the first caliper 1
The elastic force relatively rotated with the second caliper 2, so as to hinder latch components to unlock, external force only overcomes the elastic force of elastic component 8 simultaneously
Could realize that latch components are departing from unblock with the active force of limit assembly, when unblock stroke is completed, the external force of applying disappears, the
One caliper 1 and the second caliper 2 will be in maximum angle state in the presence of elastic component 8 again, and now needle forceps mouth is opened；
Generally, the stroke of latch components unblock is less, if the elastic force of elastic component 8 is less, caliper is just occurred meaning by less external force
Outer unblock, structural instability increase limit assembly, both increased the structural stability of latch components, and also improve operation can
Controlling, the comfortableness for using are improved.
As shown in Figures 2 and 3, it includes being connected to the first caliper 1 and the second caliper 2 the enforcement structure of latch components
On the first latch components 3 and the second latch components 4, first latch components 3 and the second latch components 4 include being fixed on
Lock main body 301 and the fastening piece 302 positioned at 301 end of lock main body on caliper；When fastening piece 302 is close to suitable position
When putting, will fasten to together, so as to realize the fixation to needle forceps mouth clamp position, when further increasing stroke, fastening piece
302 will depart from, until ultimate range.
Attachment structure of this utility model also to latch components with caliper is improved, as shown in figure 3, the lock master
Body 301 is after the positioning of alignment pin 303, then is fixed by welding on caliper, during assembling, first passes through 303 pairs of locks of alignment pin
Main body 301 is positioned in the position of the first caliper 1 and the second caliper 2, and is pre-fixed by alignment pin 303, Ran Houyong
Be welded to connect and be integrated, this avoid conventional screw loosen and locating effect difference problem, its structure more firm stable,
Also improve the convenience of installation.
