Description

A kind of drawing pin
Technical field
The utility model relates to a kind of setting tool.
Background technology
Drawing pin is widely used when fixedly drawing or file, but existing drawing pin head of a nail smooth surface, and the aspect is not pressed into, and also is not easy to extract after fixing, and using to people makes troubles.
Summary of the invention
The purpose of the utility model has overcome above-mentioned said deficiency, provides a kind of making to be pressed into more laborsavingly, extracts drawing pin more easily.
The utility model solves the technical scheme that its technical problem adopted: a kind of drawing pin; Comprise the head of a nail and ailhead, the head of a nail is by two cylinder affixed compositions up and down, and two cylindrical central lines and upper end cylinder diameter of section are greater than lower end cylinder diameter of section; The ailhead top is fixed in lower floor cylinder center; The ailhead bottom is a needle-like, and cylinder side, upper strata and bottom surface are provided with anti-skidding line, and head of a nail top is provided with concave surface.
During use, can ailhead be penetrated paper, finger is placed on the concave surface place of ailhead; Firmly push and make its entering, when choosing, the head of a nail has the slit between the cylinder up and down; Hold the upper strata cylinder and outwards drag and can easily it be extracted, the anti-skidding line of cylinder side, upper strata and bottom surface can increase frictional force.
The utility model compared with prior art has following advantage: simple in structure, make to be pressed into more laborsavingly, and can realize easily extracting the effect of drawing pin.
Description of drawingsFig. 1 is the three-dimensional simplified schematic diagram of the utility model.
The specific embodimentIn the three-dimensional simplified schematic diagram of the utility model shown in Figure 1; Comprise the head of a nail 1 and ailhead 2, the head of a nail 1 is by two cylinder affixed compositions up and down, and two cylindrical central lines and upper end cylinder diameter of section are greater than lower end cylinder diameter of section; Ailhead 2 tops are fixed in lower floor cylinder center; Ailhead 2 bottoms are needle-like, and cylinder side, upper strata and bottom surface are provided with anti-skidding line 3, and the head of a nail 1 top is provided with concave surface 4.
