Embodiment Construction

[0008] The technical scheme of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0009] Such as figure 1 As shown, the present invention provides a nail, including a nail cap and a nail body, the nail cap is located at the end of the nail body, and barbs are distributed on the nail body. The barbs are distributed in an inverted cone shape. It can also be a multi-thorn structure.

[0010] Concrete work process of the present invention is as follows:

[0011] 1) A nail is composed of a nail cap, a nail body, and a barb.

[0012] 2) When the user is nailing the nail, since the barb is upward, the nail is not hindered from driving in, so the resistance to nailing does not increase significantly.

[0013] 3) After the nail is nailed, the barbs provide additional clamping force because the barbs are upward, and the barbs will prevent the nails from being pulled out, so the fastness of the nails is increased.

Abstract

The invention discloses a nail which comprises a nail cap and a nail body, wherein the nail cap is positioned at the end part of the nail body, and chamfers are distributed on the nail body. Since the chamfers are additionally arranged on the nail body, the pull resistance of the nail can be improved effectively under the condition that no larger structural change is made, and the nail is simple in structure and easy to manufacture.

Description

technical field [0001] The invention relates to a nail, in particular to a nail which is difficult to pull out. Background technique [0002] General nails are very easy to be pulled out after being nailed in. Although screws are difficult to pull out, the workload of screwing in is large and the structure is relatively complicated. The invention of patent application number 94104431.9 provides a nail with an expansion end, which has an outwardly bent expansion arm formed by press-fitting. Between the expansion arms there is an axial slot which extends from the straight nail body portion before the expansion section to the front face of the nail. Another invention with patent application number 02104235.7 provides a nail, which includes a body and two legs, and the two legs are integrally formed to extend outwards from the two ends of the body in parallel; the middle part of the body is bent shape, and bend toward the direction of the extension of the two legs. The nail p...
