Abstract

The utility model provides a square wire groove body nail, including the head of a nail, nail body, nail point, the nail body is the cuboid, is equipped with the recess on four limits of nail body. The nail cap is square. The friction coefficient of the square wire groove body nail is increased, so that the square wire groove body nail can be firmly combined with an object, is not easy to loosen, reduces the using amount of the nail, and saves the cost.

Description

Side's wire casing body nail

Technical field

The utility model belongs to the fixed component field, especially relates to a kind of side's wire casing body nail.

Background technique

At present, the nail body of most nails is cylindric, generally is referred to as wire nail; The history in existing over one hundred year, but itself there is certain defective, and the nail body is smooth, friction factor is less; In use, loosening easily or come off, people's solution to this problem is to increase to measure with nail; Only in this way just can play fixing preferably or interconnect function, increase cost.

Summary of the invention

The problem that the utility model will solve provides a kind of friction factor, firm difficult loosening square wire casing body nail of increasing.

For solving the problems of the technologies described above, the technological scheme of the utility model employing is: a kind of side's wire casing body nail, comprise the head of a nail, nail body, nail point, and it is characterized in that: said nail body is rectangular-shaped, is equipped with groove at the four edges of following closely body.

Further, the said head of a nail is square.

Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, increased the surface area of nail body, the while is provided with groove on one's body at nail, increases the friction factor of nail body, in use, itself and object is connected firmly is difficult for becoming flexible.

Description of drawings

Fig. 1 is the front view of the utility model side's wire casing body nail

Fig. 2 is the worm's eye view of the utility model side's wire casing body nail

Among the figure: 1, the head of a nail; 2, nail body; 3, nail point; 4, groove

Embodiment

Like Fig. 1, shown in the front view that the utility model side's wire casing body is followed closely, a kind of side's wire casing body nail comprises the head of a nail 1, nail body 2, nail point 3, is equipped with groove 4 at the four edges of following closely body 2.

Like Fig. 2, shown in the worm's eye view of the utility model side's wire casing body nail, the said head of a nail 1 is square, in conjunction with Fig. 1, can find out that said nail body 2 is rectangular-shaped.

To follow closely body 2 and change into rectangular-shapedly, and be provided with groove 4 on the body 2, increase the surface area of nail body 2, promptly increase the friction factor of square wire casing body nail, and make itself and the object can strong bonded, be difficult for looseningly, reduce the use amount of nail, saving cost at nail.

More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.

Claims (2)
