NUT DRIVER USING MAGNET [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nut driver, and more particularly, to a nut driver using a magnet having a magnet integrally provided at an end of a driver to facilitate handling of a small nut or the like.

The term "screwdriver" refers to a tool used to remove fasteners or fasteners, such as screws or small screws, which are attached to the steel body with wooden or plastic handles.

The screwdriver may have an end which corresponds to the shape of the tightening body, such as a one-piece screwdriver used for straight-slotted screw heads and a ten-screwdriver for use with crosshead screws.

Especially, science events such as scientific inquiry nowadays allow young students to assemble science boxes or robots. Small nuts are used for scientific box or robot assembly. When using a small nut, a nut driver can be used to tighten or loosen the nut.

However, in the operation of tightening or unscrewing a small nut by using a conventional screwdriver, the screwdriver may not hold the nut firmly and may be easily lost. In addition, since the nut moves a lot, there is the inconvenience of being hand tightened or loosened.

On the other hand, when the nut is coupled to the narrow groove or the clearance in addition to the flat coupling where the nut is coupled, there is a problem in that the operation is difficult because the nut is held by hand and a driver is used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Hereinafter, a nut driver using a magnet according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. FIG.

First, a preferred embodiment of a nut driver 100 using a magnet according to the present invention will be described in detail with reference to FIG.

1, a nut driver 100 using a magnet according to the present invention includes a head portion 111 having a nut insertion hole formed at one side thereof for inserting a nut N or a screw head (not shown) A magnet M provided inside the head part 111 to guide the insertion of the nut N or the screw head and a connecting part 112 extending to the other side of the head part 111 And a grip part 120 coupled to the other side of the connection part 112 to grip the tightening part 110. [

The head portion 111 is formed in a cylindrical shape in which a nut insertion port 111A is formed so that a nut can be inserted from one side thereof, and one side is opened.

The head portion 111 may have an internal space so that a magnet M having a predetermined length may be provided therein.

The magnet M serves to induce the insertion of the nut N. When the nut N is inserted into the nut insertion port 111A, the magnet M is configured such that the nut N can be seated on one surface of the magnet M. do.

As shown in FIG. 1 and FIG. 2, the magnet M according to the present invention is shown as a cylinder having a through hole. However, the present invention is not limited thereto.

On the other hand, it is preferable that one inner circumferential surface of the head portion 111 where the nut N and the head portion 111 abut each other is configured to correspond to the outer circumferential surface of the nut N. [ In the case of a hexagonal nut, the inner peripheral surface of the head portion 111 is formed in a hexagonal shape. In the case of the ring nut, the inner peripheral surface of the head portion 111 may be formed in a cylindrical shape.

The head portion 111 has at least one size and shape to correspond to the size and shape of various nuts N and has a bar-shaped connecting portion (not shown) on the other side to be detachably coupled to the grip portion 120 112 are extended, but the present invention is not limited thereto.

The coupling between the head part 111 and the grip part 120 may be a coupling type such as interference fit or screw coupling.

The grip portion 120 may be inserted into the head portion 111 by forming a groove (not shown) on the other side of the head portion 111 so that the head portion 111 and the grip portion 120 can be coupled without the connection portion 112 . However, it should be understood that the present invention is not limited thereto, and various modifications and changes may be made by those skilled in the art.

The grip portion 120 serves to grip the tightening portion 110 and serves as a handle when the nut N is tightened or released.

One side of the grip portion 120 is coupled with the other side of the throttle portion 110 and the other side is provided with a rotation portion 121 for rotating the throttle portion 110.

In addition, the grip portion 120 may further include a non-slip portion 122 on the outer surface thereof to prevent slippage during rotation of the driver by the rotation portion 121.

As shown in FIG. 1, the non-slip portion 122 may include a plurality of protrusions protruding in the longitudinal direction on the outer circumferential surface of the grip portion 120. However, it is needless to say that the non-slip portion 122 according to the embodiment of the present invention is not limited thereto but can be implemented in various forms.

Another embodiment of a nut driver 100 using a magnet according to the present invention will be described in detail with reference to FIG. 2 is an exploded cross-sectional view of the tightening part 110 according to another embodiment of the present invention.

According to another embodiment of the present invention, a head portion 111 including a cylindrical magnet M penetrating inside to induce insertion of a nut N, and a head portion 111 coupled to the head portion 111, A throttling portion 110 having a portion 113 provided on one side; And a grip part 120 which is detachably or integrally formed with the tightening part 110.

The structure of the head part 111 and the grip part 120 is the same as that of the preferred embodiment, and a detailed description thereof will be omitted.

The second head part 113 may be detachably coupled to one side of the head part 111. [ More specifically, the second head portion 113 includes an end portion of a shape corresponding to the space formed inside the magnet M. [

2, the second head portion 113 is provided inside the head portion 111 and includes a protrusion 113B which can be inserted into the penetration portion H of the cylindrical magnet M through which the inside is penetrated, And a step portion 113C which is seated on one exposed surface of the magnet M is formed and inserted into the nut insertion port 111A of the head portion 111. [

The second head part 113 has a nut insertion hole 113A having a size different from that of the head part 111 at the other end so that the nut part N , N ') or a threaded head (not shown).

The second head portion 113 having the nut insertion hole 113A which is relatively larger than the nut insertion hole 111A of the head portion 111 is coupled to the head portion 111 so as to be relatively Can be used for tightening or separating a large-sized nut (N ').

In addition, a nut or a screw head of various sizes can be used by continuously connecting a third head part (not shown) and a fourth head part (not shown) to one side of the second head part 113 as described above Of course.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to assemble or disassemble quickly regardless of the space during assembly and disassembly using a nut, thereby preventing the nut from being damaged and allowing the worker to easily work, thereby improving work efficiency.

In addition, there is less risk of loss from assembly through the use of nuts, screws or the like to the decomposition step, and overall working time can be shortened, thereby improving workability and productivity.

The embodiments and the accompanying drawings described in the present specification are merely illustrative of some of the technical ideas included in the present invention. Therefore, it is to be understood that the embodiments disclosed herein are not for purposes of limiting the technical idea of the present invention, but rather are not intended to limit the scope of the technical idea of the present invention.
