The iron technical pen is provided with a pen holder, two holes of same size are opened at the upper part of the pen holder in coaxial and collinear manner in the vertical direction, the outer wall of the pen holder is fixed with a plastic pen body, a tapered head is arranged at the lower part of a pen clip and positioned outside the lower hole on the pen holder, a plastic tube is arranged inside the pen holder, an iron needle is fixed on the lower end of the plastic tube, the lower part of the plastic tube is provided with a protrusion that is arranged symmetrically relative to two sides of the tube, a spring is sleeved over the lower part of the protrusion of the plastic tube, two plastic rods are fixed on the upper end of the plastic tube, wherein one rod extends upwards to connect a button and the other rod obliquely extends towards the upper hole of the pen holder, and a protrusion block is arranged at the head part of the oblique rod and extends into the upper hole of the pen holder. The compass has the advantage of high safety during carrying and storage.

Description

A kind of anti-stab compasses

Technical field

The utility model relates to stationery, is a kind of anti-stab compasses specifically.

Background technology

Compasses are drawn bowlder people and are brought a lot of convenience, and the compasses that use at ordinary times, the iron pin that it is used for fixing a centre point all is fixed on the compass leg, has so just caused compasses to sting other object of damage or thorn easily when carrying and deposit and has hurted sb.'s feelings.

Summary of the invention

The utility model provides a kind of anti-stab compasses, and compasses are brought convenience when carrying and deposit and safety.

Technical solution of the present utility model is the compass leg at existing compasses, the leg hinge, handle, on the basis of flexible pencil-lead pen, though the utility model is fixed with retractable iron pin pen especially on a compass leg, iron pin pen has pen container, pen container top is on having on the axial straight line, there is a fibertip pen body that is fixed in the pen container outer wall in following two equally big holes, and a conehead is arranged at an ear bottom, conehead is in outside the next hole on the pen container, a plastic tube is arranged in the pen container, and the plastic tube lower end is fixed with an iron pin, the protuberance that the plastic tube bottom has the relative bilateral symmetry in a place to be provided with, be with spring under the plastic tube protuberance, the plastic tube upper end is fixed with two plastic bars, and a bar is directly gone up with button and is connected mutually, and other branch brace stretches to the place, upper hole of pen container, the brace head has a projection, and projection stretches in the upper hole of pen container.

Operation principle of the present utility model is when needs are used compasses, with hand by the straight-bar in the button button down pen container of retractable iron pin pen, straight-bar is depressed plastic tube, to making the iron pin expose pen container, drive spring when plastic tube moves down and become oppression state, brace on the plastic tube is subjected to downward pulling force to do the time spent simultaneously, the flexibility of the brace of plastics make projection leave upper hole and under slide in the next hole, under the elastic force effect of spring, make brace firmly withstand the next hole, even after pushing the hand of button and leaving, the iron pin can not withdrawn in the pen container yet.After using up compasses, need only the lower end of pushing the fibertip pen ear with hand, the conehead of ear lower end can stretch in the next hole of pen container and eject the projection of brace head, at this moment brace upwards slides to upper hole naturally under the elastic force of spring, the projection of brace head stretches in the upper hole, and the iron pin is withdrawn in the pen container synchronously.

The utility model has the advantages that make compasses when carrying and deposit to people's safety.
