Draw point, is that this compasses for having had collapsible draw point at present is listed, and Patents are also more, but specifically how to realize the receipts of draw point
Contract and stretch out concrete not enough, such as the Chinese utility model patent of Application No. 201210463913.8《A kind of safety compasses》,
Although it introduces a kind of contractile compasses, it describe only when pressing safety switch, and draw point stretches out, when not pressing, safety
Pin up shrinks, but specifically how to shrink after pressing, and often introduces, also without related technical clarification.
Secondly traditional lead for retractable pencil compasses are generally pressed from both sides using lead for retractable pencil, do not do any optimization design to lead for retractable pencil folder, when lead for retractable pencil ruptures,
Unclamping lead for retractable pencil folder needs with sticker to eject or beat to vibrate lead for retractable pencil to be shaken, and so processes and more bothers, and tradition
Lead for retractable pencil generally occurs lead for retractable pencil displacement when being clipped in clamping lead for retractable pencil.
The content of the invention
The purpose of this utility model is to solve the above problems, there is provided one kind can realize that draw point is collapsible and lead for retractable pencil clamping is tight
Gu, and the convenient compasses for adjusting lead for retractable pencil.
A kind of safety compasses, including handle, rotating shaft, draw point supporting leg and lead for retractable pencil supporting leg, the draw point supporting leg bottom is syringe,
The syringe is hollow structure, and the barrel sidewall is provided with J-shaped chute, and shank is provided with the syringe, and shank end is draw point,
Shank side wall is provided with a horizontal handle, and the shank bottom is cased with spring.
Preferably, less than the width of chute, the end of the handle is provided with disk, the circle to the diameter of the horizontal handle
More than the width of chute between disk.
Preferably, the lead for retractable pencil supporting leg end is lead for retractable pencil folder, and the lead for retractable pencil folder is internal to be provided with lead for retractable pencil groove, the lead for retractable pencil folder end
End is provided with screwing bolts, and the lead for retractable pencil folder middle part is provided with semicircular indentations, and the semicircular indentations overlap with part lead for retractable pencil groove.
Preferably, the lead for retractable pencil groove inner surface inside the lead for retractable pencil folder is provided with a thin layer rubber blanket.
Preferably, the surface of the rubber blanket is evenly distributed with some dots structures.
Compared with prior art, the beneficial effects of the utility model are：（1）By syringe and shank to draw point supporting leg
It is optimized design so as to the contraction of draw point can be realized, prevents draw point from injuring personal safety, and simple structure, it is easy to operate；
（2）Design is optimized to the lead for retractable pencil folder of lead for retractable pencil supporting leg, the convenient artificial lead for retractable pencil that adjusts of semicircular indentations is set and is moved up and down, and
Lead for retractable pencil folder inwall arranges one layer of rubber, is conducive to increasing the frictional force between lead for retractable pencil and lead for retractable pencil folder, and can prevent lead for retractable pencil folder by lead
Core pinch off.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage seem to become apparent from understanding, below in conjunction with accompanying drawing 1 ~ 4
And specific embodiment, this utility model is described in further detail.It should be appreciated that described embodiment herein is only
Merely to this utility model is explained, rather than for limiting protection domain of the present utility model.
A kind of safety compasses, including handle, rotating shaft, draw point supporting leg and lead for retractable pencil supporting leg, the draw point supporting leg bottom is syringe,
The syringe is hollow structure, and the barrel sidewall is provided with J-shaped chute, and shank is provided with the syringe, and shank end is draw point,
Shank side wall is provided with a horizontal handle, and the shank bottom is cased with spring.
Preferably, less than the width of chute, the end of the handle is provided with disk, the circle to the diameter of the horizontal handle
More than the width of chute between disk.
Preferably, the lead for retractable pencil supporting leg end is lead for retractable pencil folder, and the lead for retractable pencil folder is internal to be provided with lead for retractable pencil groove, the lead for retractable pencil folder end
End is provided with screwing bolts, and the lead for retractable pencil folder middle part is provided with semicircular indentations, and the semicircular indentations overlap with part lead for retractable pencil groove.
Preferably, the lead for retractable pencil groove inner surface inside the lead for retractable pencil folder is provided with a thin layer rubber blanket.
Embodiment 1
This utility model provides a kind of contractile compasses of draw point, and the compasses include draw point supporting leg, the draw point
The end of lower limb is syringe, and syringe is hollow structure, is internally provided with shank, and the end of shank is draw point, and the barrel sidewall sets
There is J-shaped chute, the shank middle part is provided with horizontal handle, and handle passes J-shaped chute, and handle end is disk, and shank bottom covers
There is a spring, spring is always shank and provides tension force upwards, when position of the artificial regulation handle on J-shaped chute metering needle is carried out
The contraction of bar is stretched out.It is J-shaped structure by art chute designs, draw point can be prevented when stretching out, leads because handle stress reason slides
Draw point is caused to shrink.
Embodiment 2
This utility model also provides a kind of convenient lead for retractable pencil supporting leg for adjusting projected length of lead, and the lead for retractable pencil supporting leg end is
Lead for retractable pencil is pressed from both sides, and is lead for retractable pencil groove in lead for retractable pencil folder, and the lead for retractable pencil folder top is provided with semicircular indentations, the semicircular indentations and part lead for retractable pencil
Groove overlaps, and lead for retractable pencil folder bottom is provided with screwing bolts, and the purpose of screwing bolts is the clamping in order to control lead for retractable pencil folder and lax,
Lead for retractable pencil rooved face punching in the lead for retractable pencil folder is provided with one layer of rubber, and rubber can increase the frictional force between lead for retractable pencil groove and lead for retractable pencil, together
Shi Nengwei lead for retractable pencils provide horizontal cushion effect, prevent lead for retractable pencil by lead for retractable pencil pinch off；The mesh of dots structure is set up on rubber blanket surface
Be, in order to further increase its buffer capacity and frictional force, further to protect lead for retractable pencil not by pinch off or be caught broken.
The effect of semicircular indentations is for convenience that with the length stretched out of hand adjustment section lead for retractable pencil, traditional lead for retractable pencil is clipped in and uses
When, when the lead for retractable pencil for stretching out use to it is shorter when, unclamp screwing bolts, now staff may be difficult to extract out from the end of lead for retractable pencil
Lead for retractable pencil, unless eject using sticker or vibrate shaken, said method is relatively complicated, designed by this utility model
Semicircular indentations precisely in order to solve above-mentioned technical problem, realization adjusts easily and fast projected length of lead because lead for retractable pencil
Top is needed through semicircular indentations, it is only necessary to is slided up and down lead for retractable pencil with thumb at semicircular indentations and is capable of achieving to adjust lead for retractable pencil
The length stretched out.
The above specific embodiment of the present utility model, does not constitute the restriction to this utility model protection domain,
Any various other corresponding change and deformation according to done by technology design of the present utility model, should be included in this practicality
In new scope of the claims.
