The content of the invention
In view of this, the utility model aims to provide a kind of drive screw, with the requirement for meeting high fastness and easily screwing out.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
A kind of drive screw, including the head of a nail, nail body, nail tip, wherein, the head of a nail is circle, is followed closely as cylinder, its one end
It is connected with the head of a nail, the other end is equipped with nail tip, and the nail tip is cone, and the upper part of the body of the nail body has screw thread, the screw thread
The half of nail body length is accounted for, its lower part of the body is provided with the first contraction flow region and the second contraction flow region, the song of first contraction flow region
Face is serrated, its section radius is 1/5th of the section radius for following closely body, and the curved surface of second contraction flow region is light picture,
Its section radius is a quarter for the section radius for following closely body, and first contraction flow region and the second contraction flow region length are respectively to follow closely
1/5th of body length and 1/10th, its spacing is 1/10th of nail body length.
Further, the jagged quantity is 16~24.
Further, the threaded hole of interior hexagonal is provided with above the head of a nail.
Further, the conical surface of the nail tip is equipped with groove.
Relative to the prior art, screw needle described in the utility model has the advantage that：
The drive screw nail body lower part of the body provided by the utility model is provided with the zigzag and the second contraction flow region of the first contraction flow region,
The threaded portion set with half body with dowel so that nail is connected more firm with by nail thing.In addition, what is set above the head of a nail is interior
The threaded hole of hexagonal, it is ensured that nail back-out is easy to operate, is easy to take out.
Brief description of the drawings

Embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
In the description of the utility model, it is to be understood that the orientation or position relationship of " vertical " instruction of term are base
In orientation shown in the drawings or position relationship, be for only for ease of description the utility model and simplify and describe, rather than instruction or
Imply that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that
Limitation to the utility model.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
With reference to figure 1, a kind of typical embodiment of the utility model provides a kind of drive screw, including the head of a nail 1, nail body 2,
Nail tip 3, wherein, the head of a nail 1 is circle, and nail body 2 is cylinder, and its one end is connected with the head of a nail 1, and the other end is equipped with nail tip 3, institute
It is cone to state nail tip 3, and the upper part of the body of the nail body 2 has screw thread 21, and the screw thread 21 accounts for the half of nail 2 length of body,
Its lower part of the body is provided with the first contraction flow region 22 and the second contraction flow region 23, and the curved surface of first contraction flow region 22 is serrated 24, institute
State zigzag 24 quantity be 20, its section radius be follow closely body 2 section radius 1/5th, second contraction flow region 23
Curved surface be light picture, its section radius is a quarter for the section radius for following closely body 2, and first contraction flow region 22 and the
Two contraction flow regions, 23 length be respectively follow closely 2 length of body 1/5th and 1/10th, its spacing for nail 2 length of body ten/
One.
In use, after the insertion of nail tip 3 is tufted into thing, the zigzag for the first contraction flow region 22 that 2 lower part of the body of nail body is set
Can more firmly it be contacted with being tufted into thing formation with the second contraction flow region 23, the screw thread 21 that the upper part of the body with dowel body 2 has,
Dual fixation is formed with object to nail body 2；The section radius of first contraction flow region 22 and the second contraction flow region 23 are too small, can influence spiral shell
The fixed intensity of line, thus require 1/5th and a quarter that its section radius is the section radius for following closely body 2.
It is preferably carried out above-mentioned in mode, the top of the head of a nail 1 is provided with the threaded hole 11 of interior hexagonal, from being followed closely
When entering thing back-out drive screw, the hexagon socket head cap screw that will correspond to model injects the threaded hole of the top of the head of a nail 1, is rotated by means of power, so as to pull out
Go out nail；The conical surface of the nail tip 3 is equipped with groove 31, and groove engages with being tufted into thing and being internally formed, and strengthens fastness.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on, should be included in the utility model
Protection domain within.
