Description

[Technical Field]

[0001] The present invention relates to a fixing aid that assists in fixing a screw to an impact driver when the screw is fastened with the impact driver. [Background technology]

[0002] Many people use impact drivers on construction sites, DIY projects, etc. Impact drivers are extremely useful tools because they can apply impact force to tighten screws.

[0003] The inventor also frequently uses impact drivers when working on his school project research. For example, the inventor performed tasks such as dismantling and building a product for a research project in the electrical engineering category of a manufacturing contest. During this research project, he used an impact driver to screw outlet boxes, lamp receptacles, and other fixtures into wall panels in precise positions. However, during this process, the screws attached to the impact driver would sometimes slip out of their holes or go in at an angle due to the force of the rotation.

[0004] Therefore, there is a demand for an auxiliary tool (screw fixing auxiliary tool) to fix the screws for impact drivers, making it easier to drive the screws. Further, as a related prior art, there is an invention described in Patent Document 1. Patent Document 1 describes a drill mounting jig, a drill device forming mechanism, and a drill device. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Problems to be solved by the invention of JP 2016-221594 A

[0006] However, the drill mounting jig described in Patent Document 1 is a jig for mounting a drill, and therefore cannot be applied to an impact driver. As a result, as mentioned above, the drill mounting jig described in Patent Document 1 cannot prevent the screw attached to the impact driver from shifting out of the screw hole or going in at an angle due to the force of rotation. Therefore, an object of the present invention is to provide a fixing aid that prevents a screw attached to an impact driver from being displaced from its screw hole or inserted at an angle due to the force of rotation.

[0007] The present invention provides a fixing aid (a screw fixing aid for impact drivers) for assisting in fixing a screw into an impact driver when the screw is fastened with the impact driver. The fixing aid is configured with a first cylindrical body, a second cylindrical body, and a third cylindrical body connected from the distal end to the proximal end, each of which is hollow and has a through-hole at the distal end and the proximal end, the first cylindrical body being one size smaller than the second cylindrical body, the second cylindrical body being one size smaller than the third cylindrical body, the first cylindrical body being connected to the second cylindrical body by a spring, and the second cylindrical body being connected to the third cylindrical body by a spring.

[0008] Furthermore, it is desirable that the fixation aid be configured such that a non-slip member is provided in the through-hole on the tip side of the first cylindrical body, and a bearing is provided around the through-hole on the base side of the third cylindrical body.

[0009] According to the present invention, the screw attached to the impact driver is prevented from being displaced from the screw hole or inserted at an angle due to the force of rotation, and the screw can be driven straight into the wallboard. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] The following describes in detail an embodiment of the present invention. However, the description of the constituent elements described below is an example (representative example) of an embodiment of the present invention, and the present invention is not limited to the following content unless the gist of the present invention is changed.

[0012] (1. Overall structure) First, the overall configuration will be described. As shown in Figure 2, a screw-fastening auxiliary tool for impact drivers (hereinafter simply referred to as "anchoring auxiliary tool") 10 according to the present invention is attached (mounted) to the tip of an impact driver 9. More specifically, a bit 11, which is an end tool that rotates to tighten or loosen screws, threads, bolts, etc., is provided at the tip of the impact driver 9. The fixing auxiliary tool 10 is then attached to the impact driver 9 by inserting the bit 11 and the screw 12 attached to the bit 11.

[0013] (2. Configuration of fixation aids) Next, the fixation aid 10 will be described. FIG. 1 is a schematic diagram of a fixing support tool 10. As shown in FIG. 1, the fixing support tool 10 is configured by a first cylindrical body 1, a second cylindrical body 2, and a third cylindrical body 3, which are connected from the distal end to the proximal end. The distal end here refers to the side where a wall panel 13 is located, and the proximal end here refers to the side where an impact driver 9 is located (see FIG. 2). In this embodiment, the first cylindrical body 1, the second cylindrical body 2, and the third cylindrical body 3 are cylindrical (columnar). In addition, in this embodiment, the first cylindrical body 1, the second cylindrical body 2, and the third cylindrical body 3 are made of transparent plastic (which allows the bits 11 and screws 12 inserted inside the cylindrical bodies to be visually confirmed).

[0014] The first cylindrical body 1, the second cylindrical body 2, and the third cylindrical body 3 are each hollow. Specifically, as shown in Fig. 1, the first cylindrical body 1 has a hollow portion 7A inside. Similarly, the second cylindrical body 2 has a hollow portion 7B inside, and the third cylindrical body 3 has a hollow portion 7C inside.

[0015] The first cylindrical body 1 is one size smaller than the second cylindrical body 2. Therefore, the first cylindrical body 1 can fit snugly inside the second cylindrical body 2. In this embodiment, as described above, the first cylindrical body 1 and the second cylindrical body 2 have a cylindrical shape, but the diameter of the circle of the first cylindrical body 1 is one size smaller than the diameter of the circle of the second cylindrical body 2.

[0016] On the other hand, the second cylindrical body 2 is slightly smaller than the third cylindrical body 3. Therefore, the second cylindrical body 2 can fit snugly inside the third cylindrical body 3. In this embodiment, the second cylindrical body 2 and the third cylindrical body 3 have a cylindrical shape, but the diameter of the circle of the second cylindrical body 2 is slightly smaller than the diameter of the circle of the third cylindrical body 3.

[0017] In short, there are three cylindrical bodies of different sizes lined up, and these are each connected by springs. Specifically, as shown in FIG. 1, the first cylindrical body 1 is connected to the second cylindrical body 2 by springs 5A and 5B. The second cylindrical body 2 is connected to the third cylindrical body 3 by springs 5C and 5D. In this embodiment, the springs 5A to 5D are coil springs, but they may also be leaf springs, disc springs, or other springs. In this embodiment, the number of springs is two (springs 5A and 5B), but it may be three, four, or more.

[0018] Furthermore, the first cylindrical body 1, the second cylindrical body 2, and the third cylindrical body 3 each have a through-hole at their distal end and proximal end. Specifically, as shown in Fig. 1, the first cylindrical body 1 has a through-hole 6A at its distal end that is connected to the hollow portion 7A. The first cylindrical body 1 also has a through-hole 6B at its proximal end that is connected to the hollow portion 7A.

[0019] Similarly, the second cylindrical body 2 has a through-hole 6C connected to the hollow portion 7B on the distal end side, and a through-hole 6D connected to the hollow portion 7B on the proximal end side. The same is true for the third cylindrical body 3. The third cylindrical body 3 has a through-hole 6E connected to the hollow portion 7C on the tip side, and a through-hole 6F connected to the hollow portion 7C on the base end side.

[0020] The fixing aid 10 has multiple through holes as described above, and the fixing aid 10 is attached to the impact driver 9 by inserting the bit 11 of the impact driver 9 and the screw 12 attached to the bit 11 through the through hole 6F of the third cylindrical body 3. 1, the hollow portion 7A of the first cylindrical body 1 tapers from the base end toward the tip end. The through-hole 6A of the first cylindrical body 1 is several millimeters larger than the cross recess of the screw 12 to be used. By tapering the hollow portion 7A in this way, the screw 12 can be fixed more firmly.

[0021] As another configuration, the tip (the tip side of the first cylindrical body 1) of the fixing aid 10 is made of rubber 8. This rubber 8 has an anti-slip effect, so when the screw is fastened, it can prevent the screw 12 protruding from the tip side of the first cylindrical body 1 from tilting diagonally or moving up, down, left, or right. Note that the rubber 8 may be formed by sticking a rubber sticker, sticking an anti-slip sticker, or applying anti-slip paint, in addition to forming the tip side of the first cylindrical body 1 from rubber.

[0022] Furthermore, the fixing aid 10 has a bearing 4 at its base end (the base end side of the third cylindrical body 3). Providing the bearing 4 prevents the fixing aid 10 from rotating together with the impact driver 9. Therefore, when fastening the screws, the fixing aid 10 can firmly fix the screws 12 without rotating, allowing the impact driver 9 to drive the screws 12 straight in.

[0023] (3. How to use an impact driver with a fixing aid attached) Finally, how to use the impact driver 9 equipped with the fixing aid 10 will be described.

[0024] (1) First, the screw 12 is attached to the bit 11 of the impact driver 9 (to the tip of the bit 11), and the fixing aid 10 is attached to the impact driver 9 (see the upper diagram in Figure 2). As described above, the fixing aid 10 is attached to the impact driver 9 by inserting the bit 11 of the impact driver 9 and the screw 12 attached to the bit 11 through the through hole 6F of the third cylindrical body 3.

[0025] (2) Then, to drive the screw 12 into the wall panel 13, the worker places the tip (rubber 8) of the first cylindrical body 1 against the wall panel 13, and while supporting the fixing aid 10 with his hand, he drives the screw 12 by pressing the impact driver 9 against the tip side.

[0026] (3-1) Then, as the worker presses the impact driver 9 against the tip, the springs 5A and 5B connecting the first cylindrical body 1 and the second cylindrical body 2 contract, and the first cylindrical body 1 enters the second cylindrical body 2. (3-2) Furthermore, as the worker presses the impact driver 9 against the tip, the springs 5C and 5D connecting the second cylindrical body 2 and the third cylindrical body 3 contract, and the second cylindrical body 2 enters the third cylindrical body 3. (3-3) In this way, springs 5A to 5D are compressed, shortening the length of auxiliary fixing device 10 in the longitudinal direction (left-right direction in FIG. 2), causing all of screws 12 to fly out of the tip of auxiliary fixing device 10 (through-hole 6A of first cylindrical body 1) and be driven into wall panel 13. Furthermore, screws 12 continue to be supported straight by auxiliary fixing device 10 (first cylindrical body 1, first cylindrical body 2, and third cylindrical body 3) until they are driven into wall panel 13, so they do not slip out of the screw hole or enter at an angle due to the momentum of rotation.

[0027] In this way, by attaching the fixing aid 10 of the present invention to the impact driver 9, the screw 12 attached to the impact driver 9 is prevented from shifting out of the screw hole or entering at an angle due to the force of rotation, and the screw 12 can be driven straight into the wall panel 13.

[0028] The fixation aid 10 described above is merely one embodiment, and the design can be modified as appropriate as long as the gist of the invention is not changed. For example, the number of cylinders (three in this embodiment: first cylinder 1, first cylinder 2, and third cylinder 3) can be increased or decreased, but if the number is increased too much, the springs connecting the cylinders will tilt, and if the number is reduced too much, it will not be able to accommodate long screws, so three, as shown in this embodiment, is preferable. [Industrial Applicability]

[0029] The present invention is a fixing aid that prevents a screw attached to an impact driver from slipping out of a screw hole or going in at an angle due to the force of rotation, and is industrially useful as it can be used in various situations such as construction sites and DIY.
