Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box driver and a bolt, and more particularly to a box driver and a bolt capable of reliably preventing the bolt from falling off.

[0002]

2. Description of the Related Art Conventionally, in tightening a screw while preventing the screw from falling off, for example, Japanese Utility Model Laid-Open No. 59-156773 discloses a screwdriver with a screw falling out prevention mechanism. This screwdriver with a screw dropout prevention mechanism opens and closes the screw holding part made by bending the spring material provided at the tip of the driver into an L shape by operating the push button provided on the driver's grip, and holding the screw. It is configured so that it can be tightened.

[0003]

However, in the screwdriver with the screw dropout prevention mechanism described in the above publication, the screw is held by the elastic force of the spring material. In the case of contact with a wall or the like, a force exceeding the holding force is applied to the screw, which may cause the screw to fall off.

Therefore, the present invention has been made in view of the problems in the above-described conventional screwdriver having a screw dropout prevention mechanism, and for the reason that the work area is narrow or the screwing point is far, the bolts are removed. An object of the present invention is to provide a box driver and a bolt that can securely hold and hold a bolt even in a situation where the user cannot hold it by hand and perform a fastening operation.

[0005]

In order to achieve the above object, the invention according to claim 1 is a box driver having a male screw portion at one end and an operating portion at the other end. And a main body having a box portion for fixing the bolt head at one end and a holding portion for holding the holding rod so as to be capable of advancing and retracting and rotating at the other end.

According to the first aspect of the present invention, when the bolt is fastened, the male screw portion of the holding rod is screwed into the female screw portion of the bolt and held, and the box head is fixed in the box portion. Rotate to screw it into the bolt screw hole. After the fastening is complete, with the bolt held by the box driver, unscrew the male threaded portion of the holding rod and the female threaded portion of the bolt, separate the holding rod and the bolt, and remove the box portion of the main unit. Pull out from the bolt head. On the other hand, when removing the bolt, the male screw portion of the holding rod is screwed into and held by the female screw portion of the bolt, and in that state, the box driver is rotated to remove the bolt. As a result, even in a situation where it is not possible to perform the fastening work while holding the bolt by hand in a place where the work area is narrow, it is possible to securely perform the fastening work while holding the bolt.

According to a second aspect of the invention, in the box driver according to the first aspect, the main body is transparent.

According to the invention described in claim 2, since the main body of the box driver is transparent, the series of operations described in claim 1 can be performed while visually confirming, so that the bolt is prevented from falling off more reliably. Can be achieved.

The invention according to claim 3 is a bolt,
The head portion is provided with a female screw portion that can be screwed with the male screw portion of the holding rod of the box driver according to claim 1 and a head portion that can be fitted with the box portion of the main body.

By using the bolt according to claim 3 and the box driver according to claim 1 or 2, in a situation where a work area cannot be tightened while holding the bolt by hand in a place where the work area is narrow. Also, it is possible to perform tightening work etc. while securely holding the bolt.

BEST MODE FOR CARRYING OUT THE INVENTION Next, specific examples of embodiments of a box driver and a bolt according to the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of a box driver (hereinafter simply referred to as “driver”) according to the present invention. The driver 1 includes a cylindrical main body 2 and a holding rod 3.
With.

The holding rod 3 is, as shown in FIGS. 3 to 7,
It is housed in the main body 2 and has a male screw portion 3a at the left end and an operation portion 3b at the right end.

As shown in FIGS. 3 to 7, the main body 2 has a box portion 2a for fixing a bolt head at a left end portion thereof, and a holding portion 2b for holding a holding rod 3 rotatably and rotatably at a right end portion thereof. . The main body 2 is preferably made of a transparent material such as tempered glass in order to facilitate the bolt fastening work described later.

FIG. 2 shows an embodiment of a bolt according to the present invention. This bolt 4 has a head portion 4a, and a female screw portion 4b which can be screwed into the male screw portion 3a of the holding rod 3 of the driver 1.
Is screwed. The bolt 4 includes a head having a hexagonal shape or a quadrangular shape, as well as any bolt having a hexagonal shape or a quadrangular shape as long as it can be rotated by fitting with the box portion 2a of the main body 2 of the driver 1.

Next, the operation of the driver 1 and the bolt 4 having the above structure will be described with reference to FIGS.

In performing the bolt fastening operation, first, as shown in FIG. 3, the male screw portion 3a of the holding rod 3 is screwed and fixed to the female screw portion 4b of the bolt 4. Next, FIG.
, The head 4a of the bolt 4 is pulled to the box 2a of the body 2 of the driver 1 by pulling the holding rod 3 against the body 2.
To fit. Then, as shown in FIG. 5, the main body 2 is rotated in the direction shown by the arrow to fasten the bolt 4 to the screw hole 5. Then, as shown in FIG. 6, with the main body 2 held and fixed, the holding rod 3 is rotated in the direction shown by the arrow to move the bolt 4
Remove from Finally, as shown in FIG. 7, the main body 2 is removed from the bolt 4, and the fastening operation of the bolt 4 is completed.

When removing the bolt 4, the procedure is the reverse of the above-described fastening operation. Specifically, first, the box portion 2a of the main body 2 of the driver 1 is fitted into the head of the bolt 4 that is fastened, and then the tip of the holding rod 3 is screwed into the female screw portion 4b of the bolt 4, so that the main body 2 is fixed. Rotate to remove the bolt 4 from the screw hole 5, and finally remove the holding rod 3 from the bolt 4.

As described above, the screw hole 5 of the bolt 4
Since the bolt 4 is screwed and held by the holding rod 3 in a series of operations of screw fastening and removal to and from, there is no risk of falling off.

[0020]

As described above, according to the present invention,
(EN) Provided are a box driver and a bolt that can securely hold a bolt even when it is not possible to tighten the bolt while holding it by hand, such as when the work area is narrow or the screwing point is far. You can
