Abstract

Disclosed is a drawing pin which comprises a nail rod and a nail head; wherein, the nail head is composed of a top surface and a bottom surface; one end of the nail rod is riveted with the bottom surface; edge teeth are arranged on the lateral surface of the nail cap. Edge teeth are additionally arranged on the lateral surface of the nail cap for convenient griping and obtaining good antiskid effect, so the operation stability is improved; the nail cap with a top surface and a bottom surface in the shape of similar arc-shaped inside and outside is changed to a structure with flat top and a concave bottom; the top surface is a plane and is more susceptible to coating with other process layers; the nail cap with plane top surface structure has good centrality degree and balanced force application; the nail rod is uneasy to be bent when the nail rod is in use; the edge teeth on the lateral surface of the nail cap can be divided into a plurality of layers, so the model is more beautiful; the antiskid property is better; the structure is simple and the fabrication cost is low.

Description

Novel drawing pin

(1) technical field

The utility model relates to a kind of daily necessities, specifically is a kind of drawing pin.

(2) background technology

Firmly drawing pin is pressed in the body of wall when using drawing pin, existing drawing pin head of a nail side is a smooth structure, skids easily, in case control bad will slipping out of the hand, operational stability is poor; The inside and outside same arc shape in the end face of the head of a nail and bottom surface, as shown in Figure 1, the end face of curve form is difficult for compound other process layer; And the drawing pin centrad of this shape is not good, and the nail bar is crooked easily during use.

(3) summary of the invention

The purpose of this utility model is the defective at prior art, and a kind of novel drawing pin is provided, and by adding edge teeth in head of a nail side, play the skidproof effect that arrives very much, has improved operational stability.

For this reason, the utility model is taked following technical scheme:

A kind of novel drawing pin includes nail bar, the head of a nail, and the head of a nail is divided into end face and bottom surface, nail bar one end and bottom surface riveted, and the side of the described head of a nail is provided with edge teeth.

Described head of a nail end face is a planar structure.

Described head of a nail side is divided into two-layer, two-layer edge teeth's symmetric arrangement up and down.

Described head of a nail side is divided into two-layer up and down, two-layer edge teeth's dislocation and arranges.

Employing the utlity model has following advantage: 1, head of a nail side is equipped with edge teeth, is convenient to grip, and plays good skidproof effect, has improved the stability of operation; 2, end face and the bottom surface with routine is that the inside and outside head of a nail with arc shape is improved to the flat recessed structure in top, and end face is the plane, easier compound other process layers; 3, the head of a nail of top surface plane structure, centrad is good, stress equalization, the nail bar is not easy bending during use; 4, head of a nail side profile of tooth can be divided into several layers, and moulding is more attractive in appearance, skid resistance is better; 5, simple in structure, cost of manufacture is low.

(4) description of drawings

Fig. 1 is existing drawing pin structural representation;

Fig. 2 is the utility model structural representation;

Fig. 3 is a head of a nail lateral edge tooth schematic diagram.

(5) specific embodiment

With reference to Fig. 2,3, a kind of novel drawing pin includes nail bar 1, the head of a nail 2, and the head of a nail is divided into end face and bottom surface, nail bar one end and bottom surface riveted, and the side of the described head of a nail is provided with edge teeth 3.Described head of a nail end face 4 is a planar structure.Described head of a nail side is divided into two-layer, two-layer edge teeth's symmetric arrangement up and down.

Certainly, as required, head of a nail side can be divided into two-layer up and down, two-layer edge teeth's dislocation and arrange.

Claims

1, a kind of novel drawing pin includes nail bar, the head of a nail, and the head of a nail is divided into end face and bottom surface, nail bar one end and bottom surface riveted, and it is characterized in that: the side of the described head of a nail is provided with edge teeth.

2, novel drawing pin as claimed in claim 1 is characterized in that: described head of a nail end face is a planar structure.

3, novel drawing pin as claimed in claim 2 is characterized in that: described head of a nail side is divided into two-layer, two-layer edge teeth's symmetric arrangement up and down.
