Description

[0001] DRIVER ADAPTED TO ELECTRIC DRILL [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric drill for use in tightening a screw, and more particularly to a driver for an electric drill in which an elastic tube is inserted into a head.

Korean Patent Application Publication No. 10-2015-0080996 (published on July 13, 2015) discloses "electric drill driver ".

Wherein a bit is formed by a shank portion and a head portion, a lower surface of the head portion is concave, and a cross-shaped tip is formed on a lower surface of the head portion so that an end portion of the cross- A small cross-shaped protrusion is formed at the center of the cross-shaped tip, and the head portion is fitted into the cylindrical bit housing, and the cross-shaped tip of the head portion is disposed inside the bit housing.

However, the driver for the electric drill is disadvantageous in that the bit housing is formed of metal, the structure is complicated, the production cost is high, and the bit housing can not hold the periphery of the screw coupled to the head part.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an elastic tube which is inserted into a head portion of a screw so that a resilient tube is fitted to the head portion of the screw, It is possible to hold the periphery of the screw smoothly, and it is possible to provide a screwdriver for an electric drill that can prevent the screw from being separated from the head portion even if the operator does not hold the screw, .

According to an aspect of the present invention, there is provided a driver for an electric drill including a shank portion gripped by an electric screwdriver and a head portion formed with a cross tip,

The head unit includes a main body formed in a cylindrical shape, a support ring integrally formed around a lower end of the main body, a cross-shaped tip formed on a distal end surface of the main body, a cylindrical elastic tube inserted in the main body, And the height of the elastic tube is formed to be higher than the height of the main body.

The elastic tube is characterized in that the elastic tube is made of rubber or a synthetic resin material having elasticity.

And the elastic tube is transparent.

Thus, the driver for the electric drill according to the present invention is characterized in that when the cross groove formed in the head portion of the screw is inserted into the screw-shaped tip of the head portion, the elastic tube is elastically deformed around the head portion of the screw So that the screw can not be separated naturally from the head part even if the operator does not hold the screw, regardless of the state of the screw, and the elastic tube can be replaced and the production cost can be reduced It is effective.

2 is an exploded perspective view showing a driver for an electric drill according to the present invention.
3 is a cross-sectional view taken along line AA of Fig. 1 showing a driver for an electric drill according to the present invention
4 is a cross-sectional view showing a state where a screw is engaged with a driver for an electric drill according to the present invention;
Fig. 5 is an exploded perspective view showing a driver for an electric drill according to the present invention having a different tip end portion of a head having a cross-

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

1 to 4, the driver for electric drill according to the present invention includes a shank portion 10 gripped by an electric screwdriver and a head portion 20 having a cross tip 24 formed therein.

The main body 21 is formed in a cylindrical shape and the head ring 20 is integrally formed around the lower end of the main body 21 and the tip end face 23 of the main body 21 is provided with a cross- The resilient tube 30 is supported by the support ring 22 and the height h1 of the resilient tube 30 is equal to or less than the height h1 of the elastic tube 30. [ Is higher than the height (h2) of the main body (21).

The elastic tube 30 is made of a synthetic resin material such as rubber or silicone.

The elastic tube 30 is preferably transparent so that the cross-shaped tip 23 of the head 20 and the screw 40 are connected.

2 and 5, the head portion 20 may have a distal end surface 23 that is flat as shown in FIG. 2, or it may be concave as shown in FIG. 5, and the cross tip 24 As shown in Fig. 2, is formed in a cross-shape on a flat front end face 23, or is formed in a cross-shape in a concave front end face as shown in Fig. 5, and a cross projecting portion is formed in the center.

The screw driver of the electric drill according to the present invention having the above-described structure is characterized in that the elastic tube 30 is fitted in the head portion 20 and the screw (not shown) The resilient tube 30 is moved around the head portion 41 of the screw 40 by the elastic force of the elastic tube 30 when a cross groove (not shown) formed in the head portion 41 of the screw 40 is inserted The screw 40 can not be separated from the head portion 20 regardless of the state in which the screw is disposed even if the operator does not hold the screw and the screw (not shown) The position of the head portion 41 of the screw 40, which is caught on the surface of the workpiece, is always kept constant regardless of the degree to which the worker applies the force. If necessary, the elastic tube 30 mounted on the head portion 20 can be replaced with a new one.
