Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holder for a driver screw which prevents a screw from easily falling off a screwdriver when the screw is tightened, and which can be manufactured at a low cost without any trouble in use.

[0002]

2. Description of the Related Art The conventional screw holding technique is to fix a screw by using a magnet having a driver shaft with a magnet or a claw-like material using a hard material.

[0003]

In holding conventional screwdrivers, magnets are provided on the shaft of the driver, and the screws are held by magnetism. However, when the magnetism is weakened or the screws are slightly attached, There was a problem that even if the screw was twisted, the screw would drop immediately.

Further, there is a problem that a magnetic driver cannot be used for a precision machine or the like that cannot use magnetism and that it is not useful for screws other than iron.

[0005] Some metal screw holders fix the screw head with a plurality of metal claws. However, since the structure is complicated, the holder itself becomes large, and the tip of the shaft of the driver is used. However, there is a problem that it is not suitable for work in narrow places such as a car engine part.

In addition, the work of attaching and detaching screws has to be performed by hand, and cannot be used for fixing screws in places that are out of reach.

[0007] In addition, those who do not have a holding tool use grease or a very small amount of quick-drying adhesive to stop the screw in order to prevent the screws from dropping. There is a problem that the screw is easily removed, and in the case of the adhesive, the adhesive is left in the groove of the tip of the screwdriver or the head of the screw.

According to the present invention, the screw is fixed by fitting the elasticity of the main part, which is a holder, and the screwdriver into the groove of the screw head.

[0009]

In order to solve the above-mentioned object, in a holder for a screwdriver according to the present invention, one of a main part which is made of a resilient material and has both open ends is provided.
A screwdriver insertion hole that can be easily inserted and removed while holding the screwdriver shaft, the other screw insertion hole for holding screws, the screw head is held with the elasticity of the main part, The screw is held by utilizing the fact that the tip of the screw enters the groove of the screw head.

[0010] The shape of the main part is such that the hem is expanded from the screwdriver insertion hole toward the screw insertion hole, or a gourd shape in which the head is partially expanded or squeezed, so as to correspond to the heads of screws of different sizes. I can do it. The position of the screw head can be adjusted when the driver is inserted into the main part from the driver insertion hole.

Further, by forming the driver insertion hole of the main part into a screw insertion hole, both openings become driver insertion holes, and both are screw insertion holes, so that both openings can be used without waste. Can be used.

Also, by providing a main part on one side of a cylinder which is open to both sides into which a driver shaft can be inserted and a holder or main part of the driver shaft on the other side, a screw is screwed to a certain extent. By pulling up the cylinder, the main part can be easily removed from the screw, and when removing the screw, the screw can be held by the main part by pushing down the cylinder when the head of the screw comes out.

A main part is provided on one of the cylinders, and the other is inserted into one of two auxiliary cylinders which are open so that the cylinder can be inserted and slid so that the length can be adjusted. By providing nothing to the opening or by providing a holder for the driver's shaft or a main part that can hold the driver, a holder that can be used by a driver with a long shaft can be adjusted in length.

The main part is mounted on the screw itself by means of a screw receiving groove or the like so that one of the main parts is provided with the screwdriver insertion hole and the other is fixed with a screw head. Screw.

The shape of the driver insertion hole and screw insertion hole, the cylinder, and the auxiliary cylinder are not limited to a circle, but may be a plurality of types such as a square and a hexagon depending on the shape of the driver shaft and the shape of the screw.

[0016]

[Operation] Insert the screwdriver into the screwdriver holder configured as described above from the screwdriver insertion hole, and insert the screw from the screw insertion hole until the screw head is fixed.
By fixing the screw inside the main part so that the tip of the screwdriver engages with the groove of the screw head, the screw can be fixed by the engagement between the screwdriver and the screw and the elasticity of the main part. The screw can be easily fixed to the driver without holding the screw.

Also, when the screw is screwed in, the main portion is not caught between the screw and the screw mounting portion because the main portion has elasticity. By pulling out the driver and pulling the main part close to the driver or removing the main part, the driver can be used in the same way as a conventional driver.

Also, when removing the screw, once the screw head comes out, pull out the screwdriver once, attach the main part to the tip of the screwdriver, and insert the screwdriver so that the main part catches the screw head. The screw can be removed without dropping the screw.

If a cylinder having a main part mounted thereon is used, when the screw is fixed to the screw mounting position, the main part is detached from the screw by pulling up the cylinder, and the head of the screw comes out when removing the screw. At this point, the head of the screw can be caught by pushing the cylinder into the screw, so that the screw can be attached or removed without interrupting the work.

By attaching an auxiliary cylinder to the cylinder, a driver having a long shaft can adjust the length of the plurality of cylinders and the auxiliary cylinder, so that the driver can be used regardless of the length of the driver shaft.

In the case of a screw having a main part, it is possible to easily maintain the screw without carrying around the main part or cylinder for the driver.

Further, when the main portion attached to the screw is screwed into the screw mounting portion, the main portion is detached from the screw and attached to the shaft of the driver due to the screwing force of the screw.

In addition, the very small screws used in eyeglasses and small devices can be easily screwed by using a main part suitable for the small screws.
