Description

Driver with auxiliary handle {Driver With Sub Handle}

The present invention relates to a driver provided with a handle, and more particularly, to a driver provided with a handle that can be detachably attached and provided with an auxiliary handle for convenient position adjustment so that a user can tighten or loosen the bolt with a small force. will be.

In general, a conventional screwdriver is formed by inserting a body having a straight or cross-shaped bolt head insert portion at a tip portion to form a screwdriver.

However, since the screwdriver has to be tightened or loosened by holding the handle by hand and pushing it with a strong force, the screw groove itself frequently wears out or breaks.

In addition, the head of the driver was also twisted or rubbed with the groove formed in the screw, which caused a lot of wear.When a strong force was released to loosen the screw, the hand and the handle of the driver were in rubbing and the palm was damaged. .

In addition, when attaching a separate removable handle to the driver, there was a problem that the position of the handle is limited.

The present invention is to provide a driver having a handle that can be removable, the handle is provided with a convenient position adjustment to tighten or loosen the bolt with a small force.

The present invention integrally forms a hexagonal auxiliary handle coupling hole 120 on one side of the hexagonal or circular driver body 100 formed with a cross head or straight bolt head insert 110 at the tip, and the auxiliary handle coupling In the driver provided with an auxiliary handle 200 is coupled to the auxiliary handle 200 is formed in the hexagonal hole 210 to be inserted into the sphere 120, the handle 300 is coupled to the rear end of the driver body 100,

Hexagonal hole 210 of the auxiliary handle 200 is characterized in that the space portion 212 is cut one end is formed.

In addition, it is installed on the auxiliary handle coupling sphere 120 of the present invention, characterized in that it further comprises a position fixing ring 400 which is fitted to the space portion 212 of the hexagon hole 210.

According to the present invention, a space portion 212 is formed in which one end of the hexagonal hole 210 of the auxiliary handle 200 inserted into the auxiliary handle coupler 120 is formed, and the auxiliary handle coupler 120 and the space portion are formed. By inserting the position fixing ring 400 between the 212, not only can easily fix the auxiliary handle 200 to the auxiliary handle coupler 120, but also easy to adjust the position and accordingly the user less force There is an advantage that the bolt can be tightened or loosened.

1 is a perspective view of a driver provided with an auxiliary handle according to an embodiment of the present invention.
Figure 2 is an exploded perspective view of a driver provided with an auxiliary handle according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

1 is a perspective view of a driver provided with an auxiliary handle according to an embodiment of the present invention, Figure 2 is an exploded perspective view of a driver provided with an auxiliary handle according to an embodiment of the present invention.

As shown in Figures 1 to 3, the driver provided with an auxiliary handle according to an embodiment of the present invention, the hexagonal or circular driver body formed with a cross head or straight bolt head insertion portion 110 ( 100) the auxiliary handle coupling sphere 120 of the hexagon formed on one side integrally, and the auxiliary handle 200 formed with a hexagonal hole 210 inside to be inserted into the auxiliary handle coupling sphere 120 is coupled, the driver Handle 300 is coupled to the rear end of the body 100, the hexagonal hole 210 of the auxiliary handle 200 is formed with a space portion 212, one end is cut.

In addition, the auxiliary handle coupling hole 120 is installed, the position fixing ring 400 is fitted to the space portion 212 of the hexagonal hole 210 is further included.

The driver body 100 is a rod-shaped cross-section formed in the shape of a circle or hexagon cross-headed or straight-shaped bolt head insertion portion 110 is formed, the rear end of the handle 300 so that the user can hold the driver and write Is fitted.

In addition, the driver body 100 has an auxiliary handle coupler 120 is integrally formed between the bolt head insertion unit 110 and the handle 300.

The auxiliary handle coupler 120 is rotated about an axis of the driver body 100 is inserted into the auxiliary handle 200, when the user grasps the auxiliary handle 200, and rotates the driver auxiliary handle 200 The driver can be rotated while supporting the position of the driver. To this end, a bearing (not shown) is positioned between the driver body 100 in which the auxiliary handle coupler 120 is installed to allow the auxiliary handle coupler 120 to rotate smoothly.

The auxiliary handle 200 has a hexagonal hole 210 is formed on one side, the handle is formed on the other end, the hexagonal hole 210 is fitted to the auxiliary handle coupling hole 120.

In other words, the cross section of the hexagonal hole 210 is formed to fit the shape of the auxiliary handle coupler 120 in accordance with the shape, and a tolerance is preferably applied for smooth fitting installation. In addition, the cross-sectional shape of the hexagonal hole 210 is, of course, depends on the shape of the auxiliary handle coupling sphere (120).

In addition, one end of the hexagonal hole 210 is formed with a space portion 212 which is cut into a chamfer or fillet along the inner peripheral end of the hexagonal hole 210 shape.

The space 212 is a space for receiving the position fixing protrusion 400.

On the other hand, the space 212 is preferably formed at both ends as well as one end of the hexagonal hole (210). This is for use by fitting to the auxiliary handle coupler 120 without the front and rear bends of the auxiliary handle 200.

The position fixing ring 400 serves to fix the position of the auxiliary handle 200 when adjusting the position after fitting the auxiliary handle 200 to the auxiliary handle coupler 120. At this time, the position fixing ring 400 is preferably a rubber material having elasticity, it is preferable to form a cylindrical donut shape.

In addition, the position fixing ring 400 is formed in a smaller diameter than the auxiliary handle coupling sphere 120, it is preferable to be fitted to the auxiliary handle coupling sphere 120 by the elastic increase.

In addition, the position fixing ring 400 is inserted into the auxiliary handle coupling sphere 120 is accommodated in the space portion 212 formed in the hexagonal hole 210 of the auxiliary handle 200, the auxiliary handle 200 is When moving along the auxiliary handle coupler 120 is fixed to the movement of the auxiliary handle 200 by the friction force.

Therefore, if you want to adjust the position of the auxiliary handle 200, first change the position of the position fixing ring 400, and then move the auxiliary handle 200 by the position fixing ring 400 by the auxiliary handle 200 ) Movement is limited.

That is, a space portion 212 is formed in which one end of the hexagonal hole 210 of the auxiliary handle 200 inserted into the auxiliary handle coupler 120 is formed, and the auxiliary handle coupler 120 and the space portion ( By inserting the position fixing ring 400 between the 212, not only can easily fix the auxiliary handle 200 to the auxiliary handle coupling sphere 120, it is easy to adjust the position.

In addition, since the user can support the driver with the auxiliary handle 200, while holding the handle 300 to rotate the driver, there is an advantage that the bolt can be tightened or loosened with a small force.
