Abstract

The utility model relates to an office supplies, especially a thumbtack, thorn frame is prevented to spine portion outer fringe suit no. 1, should prevent a thorn frame side end face with level and smooth terminal surface according to the splenium is laminated mutually, prevent that thorn frame opposite side terminal surface outer fringe is extended to spine portion homonymy and evenly make a plurality of feet of preventing stinging, a plurality ofly prevent stinging the foot is less than spine portion to the straight -line distance who prevents stinging the frame end face length a plurality ofly prevent stinging the foot and be located the outside of spine portion should be prevented stinging the foot and formed the contained angle to the vertical plane extend in the spine portion outside, the contained angle is the obtuse angle, prevent that the foot system of stinging has the easy broken line that is used for preventing stinging the rupture of foot.

Description

A kind of Thumbtack

Technical field

This utility model relates to a kind of office appliance, especially a kind of Thumbtack.

Background technology

Drawing pin is a kind of conventional fixing device, is often employed for the paper materials such as glue file, poster. But in use, there is certain problem in existing drawing pin, in the process particularly in storage, owing to drawing pin volume is only small and its press section is generally arc, therefore when drawing pin drops, its sharp portion usually sets up, and is easy to the situation that user stabbed by drawing pin occur when storage.

Utility model content

The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of rational in infrastructure, uses safety, it is simple to a kind of Thumbtack of storage.

This utility model is achieved through the following technical solutions:

A kind of Thumbtack, including press section and sharp portion, it is characterized in that: described sharp portion outer rim is set with a stab-proof frame, the flat end face of this stab-proof frame one side end face and described press section fits, described stab-proof frame opposite side end face outer rim extends to sharp portion homonymy uniformly makes multiple anti-stab foot, the plurality of anti-stab foot to the air line distance anti-stab foot the plurality of less than the length of sharp portion of stab-proof frame end face is positioned at the outside of described sharp portion, this anti-stab foot extends to form angle to the perpendicular outside sharp portion, and described angle is obtuse angle.

And, described anti-stab foot is shaped with for by the easily-folding line fractureed of anti-stab foot.

Advantage of the present utility model and having the benefit effect that

In this utility model, sharp portion can be hidden between anti-stab foot by the anti-stab foot that stab-proof frame is made, when it does not use, anti-stab foot can by sharp portion parcel and its to the air line distance of stab-proof frame end face less than the length of sharp portion, therefore when not using, sharp portion will not be stretched out by between anti-stab foot, can farthest prevent user from stabbing oneself or other people; Anti-stab foot extends to form obtuse angle to the perpendicular outside sharp portion, it is to avoid anti-stab foot forms resistance when thumb pin pressing to sharp portion side looper, it is ensured that the convenient installation of drawing pin; Easily-folding line can ensure after drawing pin has pressed, and the end of anti-stab foot fractures, it is to avoid anti-stab foot touches with the flat face installed, and under the effect of elastic properties of materials, causes loosening or coming off of drawing pin.

Fig. 2 is the partial sectional view of stab-proof frame and anti-stab foot in Fig. 1;

Fig. 3 is structural representation during this utility model use.

Detailed description of the invention

By the examples below this utility model being elaborated, described embodiment is illustrative and not restrictive, it is impossible to limit protection domain of the present utility model with this.

A kind of Thumbtack, including press section 1 and sharp portion 6, this utility model innovation is in that, in the through hole 5 that described sharp portion outer rim suit stab-proof frame 2 center is made, the flat end face of this stab-proof frame one side end face and described press section fits, described stab-proof frame opposite side end face outer rim extends to sharp portion homonymy uniformly makes multiple anti-stab foot 3, the plurality of anti-stab foot to the air line distance anti-stab foot the plurality of less than the length of sharp portion of stab-proof frame end face is positioned at the outside of described sharp portion, this anti-stab foot extends to form angle to the perpendicular outside sharp portion, described angle �� is obtuse angle, described anti-stab foot is shaped with for by the easily-folding line 4 fractureed of anti-stab foot.

Work process of the present utility model is:

During utility model works, operator press inward against press section after drawing pin sharp portion is directed at flat end face 7, in the process that sharp portion extends to flat end face, anti-stab foot extends to the outside of sharp portion, until all rupturing along easily-folding line in the end of multiple anti-stab feet, the installation of drawing pin can be completed.

Claims

1. a Thumbtack, including press section and sharp portion, it is characterized in that: described sharp portion outer rim is set with a stab-proof frame, the flat end face of this stab-proof frame one side end face and described press section fits, described stab-proof frame opposite side end face outer rim extends to sharp portion homonymy uniformly makes multiple anti-stab foot, the plurality of anti-stab foot to the air line distance anti-stab foot the plurality of less than the length of sharp portion of stab-proof frame end face is positioned at the outside of described sharp portion, this anti-stab foot extends to form angle to the perpendicular outside sharp portion, and described angle is obtuse angle.

2. a kind of Thumbtack according to claim 1, it is characterised in that: described anti-stab foot is shaped with for by the easily-folding line fractureed of anti-stab foot.
