Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screw holder for a driver, which can be operated without disassembling screws when disassembling and assembling mechanical instruments.

[0002]

2. Description of the Related Art Conventionally, there was a magnet type driver and a dedicated driver with two metal tabs at the tip of the driver.

[0003]

Conventionally, there have been the following drawbacks. (B) With a magnet type screwdriver, stainless steel screws do not adhere to the screwdriver. (B) When removing the loosened screws that were out of reach of my hands, it was difficult to pinch the screws with the two metal tabs attached to the special driver. (C) The metal claws of the dedicated driver had the drawback that they could not be repaired if they were broken. (D) In the workplace where there is no dedicated driver, I worked hard to prevent the screw from dropping by using adhesive or using adhesive tape on the tip of the driver. The present invention has been made to eliminate the conventional drawbacks, and provides a screw holder for a driver that can be easily attached to a general driver.

[0004]

[Means for Solving the Problems] A screw holder (1) made of plastic or hard rubber has a different structure in which a small-diameter cylindrical portion having a diameter that does not slide down from a driver shaft and a large-diameter cylindrical portion larger than that are integrated. It is a cylindrical cylinder with a large diameter and is provided with a large rubber ring mounting groove (4), a small rubber ring mounting groove (5), a large rubber ring storage groove (7) and a small rubber ring storage groove (8). A notch (6) is provided at the tip of the large-diameter cylindrical portion, and a large rubber ring (2) and a small rubber ring (3) are attached. The present invention is a screw holder for a driver having the above configuration.

[0005]

[Function] When the screw has a head larger than the shaft diameter of the driver, insert the screw holder with the smaller diameter into the driver, push the screw into the cylinder, hold the screw with the rubber ring, and turn the screw. If the screw has a smaller head than the shaft diameter of the driver, insert the screw holder with the larger diameter into the screwdriver, push the screw into the cylinder, hold the screw with the rubber ring, and turn the screw with the screwdriver.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, a screw holder (1) made of plastic or hard rubber has a small-diameter cylindrical portion having a diameter that does not slip off from a shaft of a driver and the same. It has a structure of a different-diameter cylindrical type cylinder in which a larger-diameter cylindrical portion is integrated, and a large rubber ring mounting groove (4) is vertically arranged in the large-diameter cylindrical portion of the screw holder (1).
Provided in two places, and further provided two cuts (6) at the tip,
Provide a large rubber ring storage groove (7). Screw holder (1)
A small rubber ring mounting groove (5) is provided at two upper and lower locations on the small diameter cylinder portion, and a small rubber ring storage groove (8) is provided. The large rubber ring (2) is attached to the large diameter tubular portion, and the small rubber ring (3) is attached to the small diameter tubular portion.

In the embodiment shown in FIG. 2, the driver (9)
When installing a head screw (10) larger than the shaft diameter of the screw holder (1), attach the screw holder (1) to the small diameter cylinder side of the screwdriver (9).
Insert the large rubber ring (2) into the large rubber ring mounting groove (4) and the small rubber ring (3) into the small rubber ring storage groove (8), and then press the large rubber ring (2) by hand. Hold the screw (10), turn the screwdriver (9) in this state, and at the end of tightening, the large rubber ring (2) will spread outward and the screw (10) will automatically come off from the large rubber ring (2). , It can be tightened without dropping the screw (10). On the contrary, as a method for removing the loosened screw (10) without dropping it, the screw holder (1)
By pushing the screw into the loosened screw (10), the large rubber ring (2) spreads outward and supports the head of the screw (10), so that the screw (10) can be removed without dropping it. Since the inside of the tip of the large-diameter cylindrical portion is the tapered portion (12), it is easy to insert a screw.

In the embodiment shown in FIG. 3, the driver (9)
When installing the head screw (11) smaller than the shaft diameter of the
Insert the small rubber ring (3) into the small rubber ring mounting groove (5) and the large rubber ring (2) into the large rubber ring storage groove (7), and then press the small rubber ring (3) by hand. In this state, the small rubber ring (3) spreads outward and can be automatically tightened without dropping the screw (11). Conversely, loosen the screw (1
As a method for removing 1) without dropping, the small rubber ring (3) spreads outward by pushing the screw holder (1) into the loosened screw (11), and the head of the screw (11) is supported. It can be removed without dropping the screw (11). The inside of the tip of the small diameter cylinder is tapered (1
Because of 3), it is easy for screws to enter.

[0009]

Since the present invention is constructed as described above, it has the following effects. By simply inserting the screw holder into a commercially available screwdriver, you can easily disassemble and assemble the machine tool without dropping the screw, and by installing a rubber ring and a cut, you can change from small screws to large screws. It can be used with many types of screws, and can also be used with stainless steel screws that do not adhere to magnet type drivers. You can use it for any driver without a dedicated driver, and by moving the screw holder toward the driver's grip, you can perform normal work without any trouble. Further, the screw holder does not have any metallic part, and does not damage the product when disassembling and assembling a precision machine or the like. At work sites where gloves are used in clean rooms, etc., when performing machine maintenance, the screws are often dropped, but by using a screw holder, it is possible to work without dropping the screws, and there are no machine problems and work efficiency is improved. . This tool can also be used with a hexagon wrench. In this case, the shaft insertion portion may be hexagonal, and the rubber ring, the rubber ring mounting groove, and the rubber ring storage groove are not necessarily required.
