Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a nail adjustment tool for a pachinko machine.

[Prior Art] Conventionally, pliers have generally been used as this type of nail adjustment tool.

[Problems to be solved by the invention] However, the conventional pliers had a problem in that the handles were too bulky to fit into a pocket or the like, making it inconvenient to carry.

SUMMARY OF THE INVENTION The present invention is intended to solve the problems of the prior art, and its purpose is to provide a nail adjustment tool that is convenient to carry and easy to operate.

[Means for Solving the Problems] The present invention is intended to achieve the above object, and the contents thereof will be explained below using embodiments shown in the drawings.

The present invention consists of an outer cylinder 2, an inner cylinder 3 which is slidably held within the outer cylinder, and which is located between the inner cylinder and the outer cylinder, and which constantly biases the inner cylinder in the backward direction with respect to the outer cylinder. A biasing means (for example, a coil spring 4) is held at the tip of the inner cylinder so as to be openable and closable, and when the inner cylinder retreats due to the biasing force of the biasing means, it is at least partially retracted into the outer cylinder. When pressed by the inner circumference of the outer cylinder, the mating surface 5' is closed, and a nail 6 is inserted between the two mating surfaces.
a pair of beak-shaped tip fittings 5 that sandwich the from both sides;
An opening means (e.g., a split pin 7) that opens the tip end fitting protruding from the open end of the outer cylinder when the inner cylinder is advanced relative to the outer cylinder against the urging force of the urging means. It is characterized by:

In addition, a pocket clip 20 is attached to the outer surface of the nail adjuster 1.
may be provided.

[Operation] Therefore, when the inner cylinder 3 is moved forward relative to the outer cylinder 2 against the urging force of the urging means 4, the tip fitting 5 also moves forward and partially protrudes from the open end of the outer cylinder. Due to the action of the opening means 7, the mating surfaces 5' of both end fittings are opened.

In this way, when the nail 6 is positioned within the gap between the two opened end fittings and the force is released, the inner cylinder is retracted by the urging force of the urging means, and the end fitting is partially retracted into the outer cylinder. At this time, the outer surface of the tip fitting is pressed against the inner periphery of the outer cylinder, and both mating surfaces are closed. Therefore, both end fittings are pulled into the outer cylinder in a state where the nail is bitten between both mating surfaces, and the nail is clamped from both sides.

In this clamped state, when the outer cylinder is tilted in the direction in which the nail is to be bent, the nail will be bent in the direction in which the outer cylinder is tilted, while being clamped between the mating surfaces of the end fitting.

After the nail has been adjusted, when the inner cylinder is moved forward again against the outer cylinder against the urging force of the urging means, both end fittings open and the nail is released.

On the other hand, when carrying, the nail adjuster 1 is inserted into a pocket (not shown) and fastened with the pocket clip 20.

[Example] The present invention will be described below based on an example shown in the drawings.

In the figure, 1 indicates a nail adjustment tool, and this nail adjustment tool 1
is a pipe-shaped outer cylinder 2, an inner cylinder 3 that is one size smaller than the outer cylinder 2 and is slidably held within the outer cylinder 2, and an outer cylinder located between the inner cylinder 3 and the outer cylinder 2. 2
A coil spring 4 serves as a biasing means for always urging the inner cylinder 3 in the backward direction, and the inner cylinder 3 is held openable and closable at the tip of the inner cylinder 3, and the inner cylinder 3 is moved backward by the restoring force of the coil spring 4. As a result, the nail 6 is at least partially drawn into the outer cylinder 2, and at that time, it is pushed by the inner circumference of the outer cylinder 2 to close the mating surfaces 5', 5', and the nail 6 is held between both mating surfaces 5' from both sides. a pair of beak-shaped tip fittings 5, 5; and a tip fitting that protrudes from the open end of the outer tube 2 when the inner tube 3 is advanced relative to the outer tube 2 against the restoring force of the coil spring 4. An interrupt pin 7 is provided as an opening means for opening 5.

The inner cylinder 3 has a longer overall length than the outer cylinder 2, and has longitudinally long slide grooves 8, 8 formed opposite each other in the middle of its length, and slides into both slide grooves 8 from the outer periphery of the outer cylinder 2. A series of pins 9 are passed through, their tips protrude from the outer periphery of the outer cylinder 2 on the opposite side, and the protruding ends are caulked and fixed. Furthermore, a short cut cylindrical cap 10 having the same diameter as the outer cylinder 2 is fitted into the rear end of the inner cylinder 3 protruding from the rear end of the outer cylinder 2.
A series of fixing pins 11 are passed through the inner cylinder 3 from the outer circumference of the inner cylinder 3 and fixed by caulking in the same manner.

The coil spring 4 is compressed between the slide pin 9 and the fixed pin 11, and uses its restoring force to constantly urge the inner cylinder 3 in the backward direction with respect to the outer cylinder 2.
Before fixing the cap 10 with the fixing pin 11, the coil spring 4 is inserted from the open rear surface of the inner cylinder 3, and placed with one end in contact with the slide pin 9, and the other end is inserted into the rear with the fixing pin 11. Press it down to prevent it from coming out from the inner cylinder 3.

The tip fitting 5 has a symmetrical shape with both mating surfaces 5' in between, and when the mating surfaces 5' are closed,
Fit the rear end into the inner cylinder 3, and pass the stop pin 12 in a series from the outer periphery of the inner cylinder 3 in a direction perpendicular to the mating surface 5'. Fix it so that it opens.

That is, as shown in FIG. 3, the rear end of the tip fitting 5 is provided with a through hole 13 that passes through it laterally and into which the stop pin 12 is loosely fitted. Fix it by passing the fixing pin 12 through it. still,
Both ends of the retaining pin 12 are slightly caulked to prevent it from coming off.

The mating surface 5' of the tip fitting 5 has a retaining groove 14 having a semicircular cross section with one end open to the distal end surface and the other end extending halfway backwards, and a retaining groove 14 facing the other end of the retaining groove 14 and extending laterally. Inset portions 15 penetrating in a circular shape are formed to face each other. Further, at the rear end of the mating surface 5' of the tip fitting 5, a mating groove 16 having a relatively large semicircular cross section and having both ends penetrating vertically is formed facing each other.

Further, on the upper and lower surfaces of the tip fitting 5, there are chevron-shaped convex portions 1 that are raised outward and are approximately equal to the inner diameter of the outer cylinder 2.
7, 17 are formed. Also, on the outer surface facing away from the mating surface 5', a chevron-shaped protuberance 18 that protrudes outward and is approximately equal to the inner diameter of the outer cylinder 2 is formed, and the through hole 13 is formed laterally at the rear end. A stepped portion 19 is formed which is opened at the bottom and is lowered by a step.

On the other hand, the interrupt pin 7 passes vertically from the outer periphery of the outer cylinder 2 through the space between the mating grooves 16 of both end fittings 5, and is crimped at both ends to prevent it from coming off.

Further, the L-shaped bent end of the pocket clip 20 is welded or glued to the rear end of the cap 10.

Next, the procedure for using the assembled nail adjuster 1 will be explained. To open the tip fitting 5, while holding the outer tube 2, resist the spring force of the coil spring 4.
All you have to do is knock on the cap 10.

As a result, the inner cylinder 3 moves forward inside the outer cylinder 2, and at this time the slide pin 9 moves relatively along the slide groove 8, compresses the coil spring 4 between it and the fixed pin 11, and exerts a restoring force. Accumulate.

On the other hand, the tip fitting 5 moves forward together with the inner cylinder 3,
At that time, the split pin 7 fixed to the outer cylinder 2 aligns with the groove 1.
6 and intersects between the two mating surfaces 5', thereby gradually increasing the distance between the two mating surfaces 5' (FIG. 4).

That is, the stop pin 12 is inserted into the through hole 13 of both end fittings 5.
Because it is loosely fitted into the inside and there is a gap between the stepped portions 19 of both end fittings 5 and the inner periphery of the inner cylinder 3, the tip of the end fitting 5 can be moved outward from the left and right around the stop pin 12. Open in the direction.

When the mating surfaces 5' of both end fittings 5 are opened in this manner, a nail 6 driven into the board surface 21 of a pachinko machine (not shown) is positioned within the gap. At that time, the head 6a of the nail 6 is
Then, when the shaft portion 6b is positioned in the holding groove 14 and the pushing of the cap 10 is stopped, the coil spring 4 is expanded by the accumulated spring force, and the inner cylinder 3 is moved back relative to the outer cylinder 2. let

Therefore, the tip fitting 5 also retreats together with the inner cylinder 3,
The inclined rear surface 17' of the convex part 17 and the inclined rear surface 18' of the raised part 18 contact the inner circumference of the outer cylinder 2, and are pushed radially inward by the upward slope of these slopes, and at the same time the interrupt pin 7 Mating groove 1 from between both mating surfaces 5'
By relatively moving within the interval of 6, both mating surfaces 5' of the end fitting 5 gradually close. At this time, the shaft portion 6b of the nail 6 is held from both sides by the holding grooves 14 of the mating surfaces 5' of the end fitting 5 (FIGS. 1 and 2).

In this state, when the outer tube 2 is tilted in the direction in which the nail 6 is desired to be bent, the nail 6 is held between the mating surfaces 5' of the end fitting 5 and bent in the direction in which the outer tube 2 is tilted.

In addition, at that time, the head 6a of the nail 6 is attached to the tip metal fitting 5.
The head 6a of the nail 6 fits into the fitting part 15 of the nail 6.
It won't hurt.

After the nail 6 has been adjusted, the cap 10 is knocked again and the nail 6 is removed from between the open mating surfaces 5'.

On the other hand, when carrying it, the nail adjuster 1 is inserted into a pocket (not shown) and fastened with the pocket clip 20. This prevents the nail adjuster 1 from falling out of the pocket.

FIG. 5 shows another embodiment of the present invention, in which a compression spring 22 is used as the opening means for opening the tip fitting 5.

That is, blind holes 23 are provided on the mating surface 5' of the end fitting 5 so as to face each other, and both ends of the compression spring 22 are fitted into the blind holes 23. Thereby, the distal end fitting 5 is always urged open by the restoring force of the compression spring 22, so that it opens when protruding from the outer cylinder 2. Note that a leaf spring may be used instead of the compression spring 22.

In the embodiment shown in the drawings, the convex portion 1 of the tip fitting 5
7 and the protrusion 18 are raised approximately equal to the inner diameter of the outer cylinder 2 of the tip metal fitting 5, but they may be raised radially outward to a larger extent than the inner diameter of the outer cylinder 2, or the protrusion 17 and The protrusion 18 may not be provided and the outer surface of the tip fitting 5 may be placed flat. However, if it is placed flat, the outer surface of the tip fitting 5 needs to be approximately equal to or smaller than the inner diameter of the outer cylinder 2 so that the tip fitting 5 closes when retracting.

Further, although the fitting portion 15 of the tip metal fitting 5 is formed as a through hole passing through it laterally, it may be in the form of a blind hole as long as the head 6a of the nail 6 fits therein.

Furthermore, although the pocket clip 20 is fixed to the cap 10, it may be fixed to the outer periphery of the outer cylinder 2.

[Effects of the Invention] As explained above, according to the present invention, it is possible to provide a nail adjustment tool that is convenient to carry and easy to operate. Also, since it is provided with a pocket clip, it can be prevented from falling out when it is put into a pocket or the like.
