Abstract
The utility model discloses a pin which comprises a pinhead and a pin body. The pinhead and the pin body are connected to be a whole to form an oval sheet structure. A protruding point is arranged on the lower wall of the pinhead. A groove matched with the protruding point is formed in a normal contact portion of the pin body and the pinhead. The pin has the advantages of being simple in structure so that files are prevented from being scratched and the phenomenon of falling of a file is not prone to happen even if the pin is used for clamping the file with a few pieces of paper.
Description
Technical field
The utility model relates to the office facility field, is specifically related to a kind of safety pin.
Background technology
Traditional safety pin majority that is used for the folder file all is clip; the corner angle that have that present these clips all are metals easily scratch file; slightly better is at safety pin cover one deck plastic protective layer; but for the fewer file of number of paper, these traditional clips all cause trouble than being easier to come off.
Summary of the invention
In order to overcome the defective of prior art, the utility model provides following technical scheme:
A kind of safety pin comprises syringe needle and the needle body, and described syringe needle and the needle body are connected and are the laminated structure of ellipse, is provided with salient point at the lower wall of described syringe needle, offers the groove that is complementary with described salient point at the described needle body and place, the normal contact of syringe needle.
Further, described syringe needle and the needle body all do not have corner angle.
The beneficial effects of the utility model are: simple in structure, and can not scratch file and be not easy to occur the file obscission at the less file of folder number of paper yet.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure:
1, the needle body; 2, syringe needle; 3, salient point; 4, groove.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
As shown in Figure 1, a kind of safety pin, comprise syringe needle 2 and the needle body 1, syringe needle 2 and the needle body 1 are connected and are the laminated structure of ellipse, lower wall at syringe needle 2 is provided with salient point 3, offers the groove 4 that is complementary with salient point 3 at the needle body 1 with place, syringe needle 2 normal contact, can engage when number of paper is less like this so that file is not easy to come off, and the utility model syringe needle 2 and the needle body 1 all do not have the integral structure of corner angle to be not easy to scratch file, and outward appearance is finer.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
Claims (2)
