Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a screw.

[0002]

[Prior art]

 The nails formed from various materials are iron nails or steel nails. Usually, the nail is formed in a smooth rod shape, a nail cap is formed on the head, and the end is formed in a circular or polyhedral cone. The nail is driven into the target and fixed, and has the following advantages. (1) Nail driving is easy because it is driven into a target by a tool such as a hammer.

(2) Driving quickly. (3) Can be extracted by a tool. However, nails have the following disadvantages. (1) Since it is a smooth rod, the force with a nail is small and it is relatively easy to fall off.

(2) If the nail is mistakenly hit with a tool such as a hammer, the nail is bent. (3) When the nail head is completely driven into the target by a tool such as a hammer, the surface of the target is easily damaged. (4) Noise is generated when a long nail is driven into a target. (5) When the nail is pulled out of the target, the surface of the target may be scratched by a tool.

(6) It is impossible to reuse a nail hole. Thus, screws are used. The conventional screw is screwed and fixed to a target object by a spiral method, and has the following advantages. (1) The fixing force is increased by the screw structure, and it is hard to fall off. (2) The screw holes can be used again.

(3) Noise is reduced. (4) The surface of the target is not damaged by screwing or screwing. However, conventional screws have the following disadvantages. (1) Since the screw is screwed into the target, the initial resistance is large and the screw may not be screwed correctly due to the inclination. It is difficult to determine the position, and the surface of the target is easily damaged by the movement of the screw.

(2) The speed of being screwed into the target is slow, and the construction time increases. (3) If the length of the screw is long, the labor for construction increases.

[Problems to be solved by the invention]

 Therefore, an object of the present invention is to provide a screw which can be used easily and requires less labor.

[0009]

[Means for Solving the Problems]

 The screw according to the present invention includes a nail head rotated by a rotary tool, a body formed in a parallel or substantially parallel rod shape, and a distal end formed in a pointed shape. . The body has a spiral stage having a screw structure at the front stage and a rod-shaped nail stage having no screw structure at the rear stage. The distal end is formed in a nail step and is formed in a conical or polygonal pointed shape. The nail head extends from the front end of the spiral step and is formed so that it can be nailed, screwed in or unscrewed.

[0010] The screw is rotated and tightened after the distal end is driven and positioned. Therefore, it can be easily used and labor can be reduced.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a screw according to an embodiment of the present invention includes a nail head 11 rotated by a nailing and rotating tool, a spiral rod, and a parallel or substantially extending rod extending from the spiral rod. It has a parallel rod-shaped nail bar, and a distal end formed in a conical or polyhedral pointed shape.

Extending from the helical rod is a nail step 12 that does not have a parallel or nearly parallel rod-like thread structure. The nail step is formed in a pointed shape with a conical or polyhedral cone at the end, and when the nail head 11 is nailed, the end of the nail step is driven into the target. On the nail body of the nail head 11, a spiral step 13 formed in a parallel or almost parallel rod or cone shape extends. A screw structure is formed in the spiral step 13 in the radial direction, and a nail body step 12 having no screw structure extends from an end of the spiral step 13.

As shown in FIG. 2, a screw 1 is formed by a nail step 12 and a spiral step 13 having no screw structure. The nail 1 is driven into the target by the hammer 20 and the screw 1 is positioned and fixed. As shown in FIG. 3, when the nail stage 12 is driven into the target, a general automatic or manual rotating tool 30 is connected to the nail head 11, and the rotating operation is performed. Since the spiral stage 13 is screwed into the target, it is firmly nailed, the noise is low, and the destruction of the surface of the target is prevented. When the spiral step 13 is rotated in the reverse direction, the screw 1 is pulled out, and the nail step 12 is pulled out of the hole formed by the spiral step 13. Therefore, no nailing tool is required and destruction of the target surface is prevented. The screw hole can be used again for tightening the screw 1.

As shown in FIG. 1, the nail head 11 is formed with a (−)-shaped groove 111 at the top end of the nail head 11 like a conventional screw so as to be connected to the rotary tool 30. As shown in FIG. 4, the nail head 11A of the screw 1A is formed with a (+)-shaped groove 112A crossing the top end so as to be connected to the rotary tool 30, and the groove 112A is pneumatic, manual, or manual. Alternatively, it is rotated by being coupled with a power-driven or manual rotary tool. As shown in FIG. 5, the nail head 11B of the screw 1B is formed with an intersecting groove 112B at the top end so as to be coupled to the rotary tool 30, and the intersecting groove 112B is located on the side of the nail head 11B. It extends to the edge and is rotated by being combined with a general pneumatic, manual or other mobile or manually driven rotary tool. In addition, other geometrical coupling structures are formed.

One or more grooves are formed in the nail body of the screw in the axial direction. The screw is driven into the target by a method that is driven directly into the groove or after being driven in, by a method that is tightened. Also, the screw can be pulled out after being loosened. As shown in FIGS. 6 and 7, the screw 1 </ b> C according to another embodiment of the present invention has a spiral step 13 </ b> C in which the screw structure is formed intermittently in the radial direction. The spiral step 13C is formed with one parallel, spiral, regular or irregular spiral groove 14C. The screw is driven in by a direct driving method, driven in by a tightening method, rotated, and then pulled out. As shown in FIGS. 8 and 9, the screw 1D has a nail step 12D having no screw structure, and the spiral step 13D has two parallel, spiral, regular or irregular spiral openings. A groove 14D is formed. As shown in FIGS. 10 and 11, the screw 1E has a nail step 12E having no screw structure, and the spiral step 13E has three parallel, spiral, and other regular or irregular shapes. A spiral cutout groove 14E is formed. Also, more open grooves are formed, and the construction effect is improved.
