Due to the adoption of the technical scheme, the barbs are arranged on the thumbtack rod of the thumbtack, the force of fastening the thumbtack in a wall can be enhanced, and the thumbtack is not easy to fall off to hurt a human body during use.
Description
Technical field
The present invention relates to a kind of drawing pin.
Background technology
Present drawing pin on the market all is straight formula drawing pin; Straight formula drawing pin has the convenience of use; Its easily puncture and convenient taking-up when the user wants to use drawing pin to fix things in wall or notice board; But this drawing pin in use drops easily, and drawing pin drops and be difficult for probably on the ground coming to light, and but when careless, human body is damaged.
Summary of the invention
Technical problem to be solved by this invention provides a kind of drawing pin, can strengthen the strength that drawing pin is grabbed wall, makes difficult drop-off in this drawing pin use and human body is damaged.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: drawing pin, comprise the head of a nail and nail bar, and said nail bar is provided with at least one barb, and the length of said barb is 1/5～1/6 of said nail pole length.
As preferably, said barb is located at 1/2 position from said nail bar end to said nail pole length.
As preferably, the tip of said barb circle is blunt.
As preferably, said nail bar is provided with a plurality of barbs, and said barb is along the axial distribution of nail bar.
As preferably, said nail bar is provided with a plurality of barbs, and said barb is in spiral distribution along the nail bar.
As preferably, the top of the said head of a nail is provided with groove.
The present invention is provided with barb owing to adopted technique scheme on the nail bar of drawing pin, can strengthen the strength that drawing pin is grabbed wall like this, makes difficult drop-off in this drawing pin use and human body is damaged.
Description of drawings
Fig. 1 is the structural representation of drawing pin of the present invention
Fig. 2 is the vertical view of drawing pin shown in Figure 1
The specific embodiment
Further describe below in conjunction with the accompanying drawing specific embodiments of the invention.
Shown in Figure 1 is drawing pin of the present invention, comprises the head of a nail 1 and nail bar 2, and said nail bar 2 is provided with at least one barb 3, and the length of said barb 3 is 1/5～1/6 of said nail bar 2 length, is longer than this length, and barb can let the user be difficult to take out.Said barb 3 is located at 1/2 position from said nail bar 2 ends to said nail bar 2 length.The tip of said barb 3 circle is blunt, and barb injures the user when avoiding the use of this drawing pin.
Can be provided with a plurality of barbs 3 on the said nail bar 2, said barb 3 is along nail bar 2 axial distribution or in spiral distribution along nail bar 2.
As shown in Figure 2, the top of the said head of a nail 1 is provided with groove 4.Said groove 4 is in-line groove or cross groove.So that use screwdriver to come this drawing pin of removal under special circumstances.
Because there is barb equally can easily hammer into wall or notice board with common drawing pin in that thorn is fashionable; But also simultaneously because barb is arranged; So under neglectful situation, can't come off so easily; When needs take out,, can not cause the situation that is difficult to take out because barb length is not long yet.
