Abstract

The present invention relates to a screwdriver tool that loosens or tightens a screw nut, and is proposed by solving the problem that the screw nut is not worn or loosened by the driver tool tip when tightening or loosening the + (cross) type nut. It is an object of the present invention to provide a cross screwdriver structure in which a + (cross) tip portion 13 of a + (cross) screwdriver that is commonly used is combined with a-(date) tip portion 12.

Description

Cross type screw driver

The present invention relates to a screwdriver tool for loosening or tightening a screw nut. The present invention relates to a screw driver tool that solves the problem that a nut groove is not worn or broken by a screwdriver tool tip when tightening or loosening a + (cross) nut. A combined cross screwdriver tool.

In general, it relates to a tool used to tighten or loosen a nut using a screwdriver of + (cross) or-(date) shape depending on the screw nut shape.

1 is a perspective view showing the distal end of a conventional + (cross) type screwdriver.

In the conventional driver, the tip 13 of the + (cross) type driver blade having a predetermined inclination is formed symmetrically with each other, and is used to loosen or tighten by turning the screwdriver groove 21 to the left and right as shown in FIG.

 FIG. 7 is a chassis diagram illustrating a cross-shaped driver bit in which + and − are used in connection with a detachable driver or an electric driver.

As shown in FIG. 8, when the strong force of the driver is transmitted, the + (cross) type nut jaw 23 is in a worn or broken nut 24 state, and the screwdriver does not function as a nut because the screw driver turns around in the screw nut. . In this case, it takes a lot of time to remove the defective nut during the assembly of the product, or it could not be pulled out to become a defective product.

The present invention has been proposed in order to solve the above problems, a part of the + (cross) tip 13 of the + (cross) type screwdriver that is generally used to the-(date) tip 12 The purpose is to provide a combined cross (†) screwdriver structure.

Combination type screwdriver according to the present invention is a combination of two in a straight line of the + (cross) driver tip portion 13 connected to the body 11 of the general driver in Figure 1 to-(date) type driver tip portion 12 Cross-shaped (†) screw nut and driver tip contact surface 22 in Fig. 9 are first closed in Fig. 9, and a cross (†) of + (cross) and-(date) of the screwdriver as shown in Fig. 7 is used. ) Is characterized in that it comprises a screwdriver tip.

Wear and damage of the jaw 23 of the + (cross) nut by a general hand driver or an electric screwdriver by using a cross screwdriver combining the + and-screwdrivers conceived by the present invention as described above. It can prevent the problem that occurs during the screw-driving work required for production assembly products or repair, which can save the working time and prevent the product defects caused by the damage.

The above and other specific objects and features of the present invention will be apparent from the following description of the drawings.

1 is a perspective view showing the distal end of a conventional + (cross) type screwdriver.

In the conventional driver, the tip 13 of the + (cross) type blade having a constant inclination is formed symmetrically with each other, and is inserted into the screw nut groove 21 as shown in FIG. 6 to be used to loosen or tighten it.

Fig. 2 is a chassis diagram of a cross screwdriver combining + and − as an embodiment of the present invention.

As described above, the present invention is a combination of the inclined tip portion 13 of the general + (cross) type driver by the addition of the straight tip portion 12 of the-(date) type driver to transfer the rotational force to the screwdriver. (Date) The force is distributed to the jaw 22 of the nut groove so that the screw nut can be easily tightened or loosened without being worn or damaged.

3 and 4 are plan views of the side and head of the cross screwdriver in which + (cross) and-(date) are combined.

9 and 10 show a plan view and a cross-sectional view of a conventional screw nut head combination of + and −, which can be easily obtained from a tool store or the like.

As mentioned above, it is possible to use nut assembly in industry and home more easily without screw breakage in using for screwdriver or driver bit which combined + (cross),-(date) proposed by the present invention. And you can see the convenience.
