Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention can be used for improving the efficiency of fishing fish, etc., because the fishing hook and other needle tips can be ground very easily.

[Conventional technology]

The sharpening of the tip of a fishing hook or the like is necessary for almost all needles.

In the conventional polishing method for these needle tips, in the case of a small needle tip, a small fine grindstone is held in the hand and the needle tip is rubbed very carefully.

Further, in the case of a large needle tip, it was often done by rubbing the needle tip with a disc type grindstone that was electrically rotated.

[Problems to be solved by the invention]

In the case of a particularly small needle tip among the above, fixing the needle tip is not easy, so it is difficult to adjust the angle between the grindstone and the needle tip,
The polishing requires skill, and in the case of a large needle tip, there is a problem that the polishing device becomes large.

The present invention relates to the structure of a needle tip polisher that eliminates the above problems.

[Means for solving problems]

In order to eliminate the above-mentioned problems, the present invention arranges an abrasive material such as a grindstone for polishing the needle tip so as to sandwich both sides of the needle tip, which is then driven by an electric motor, for example, a motor. (EN) Provided is a device structure capable of easily and surely polishing a needle tip by vibrating in a direction along the direction.

〔Example〕

In FIG. 1, a motor 2 is attached to a case 1 by a fixing screw 3, and an eccentric cam 13 is fixed to an upper end of a shaft 4 of the motor so that the lower end of a vibrating portion 8 contacts an inner surface of a contact wall 81. The eccentric cam 13 is rotated at any position.

The bearing 5 is fixed to the case 1 with a fixing screw 6, and supports a shaft 7 serving as a fulcrum of a vibrating portion 8.

The contact wall 81 at the lower end of the vibrating portion 8 is made of a material such as nylon having a small friction.

The eccentric cam 13 is made of a material such as brass that can be securely fixed to the shaft 4 of the motor by press-fitting and adhesion. The surface of the eccentric cam 13 is finished to be smooth so that friction with the contact wall 81 is small.

The vibrating reed 10 bent into an acute angle and formed into a V shape is fixed to the vibrating portion 8 by a fixing screw 9 or the like, and abrasives 11 and 12, such as a thin ceramic grindstone, are attached to the inner surface bent into the acute angle. To glue.

The vibrating piece 10 is preferably made of a non-abrasive material such as an aluminum plate that is lightweight and has high workability.

FIG. 2 shows the posture of the vibrating portion 8 when the shaft 4 of the motor rotates to a position where the eccentric cam 13 pushes the contact wall 81 to the right end, and the shaft 7 serves as a fulcrum and the upper end of the vibrating portion 8 is shown. The state where the vibrating reed 10 fixed to is tilted to the left is shown.

The posture line 82 indicates that the shaft 4 of the motor has rotated half a turn and the eccentric cam 1
3 shows a situation in which the contact wall 81 is pressed to the left end and the vibrating portion 8 is tilted to the right.

As can be seen from the description of FIG. 1 and FIG. 2, as the motor 2 rotates, the vibrating piece 10 reciprocates like a pendulum about the shaft 7 as a fulcrum, and the amplitude of the movement is Width θ until the resonator element 10 shown in FIG. 2 moves to the line 82 of the posture
Is.

Therefore, if a tip of a fishing hook or the like is inserted into a sharp-angled space surrounded by the abrasives 11 and 12, and the needles are brought into contact with the abrasives 11 and 12 while rotating the motor 2, the abrasives 11 and 1
The vibration of 2 can polish the tip of the needle.

FIG. 3 shows an eccentric shaft used in place of the eccentric cam 13 shown in FIGS. 1 and 2, and an eccentric shaft 14 having a projection eccentric to the shaft 4 is provided on the motor shaft 4 similarly to the eccentric cam 13. Vibration part 8
The vibrating reed 10 can be pendulum-moved by alternately pressing the hitting wall 81 at the lower end of the vibrating piece 81 to the right and left ends.

The selection of the eccentric cam 13 and the eccentric shaft 14 mainly depends on whether the work is suitable or not.

In FIG. 4, the battery 15 is for supplying power to the motor 2 and electric wiring is omitted.
To the pendulum-like reciprocating motion by rotating the shaft 4 of the abrasives 11 and 12.

The protective cover 17 is removed during use of the present invention and is provided to protect it from intrusions such as rainwater during storage, and its material is preferably a plastic material together with the case 1.

The shape of the vibrating reed 10 can be changed by the method of fixing it to the vibrating portion 8, but the space bent at an acute angle for fixing the abrasives 11 and 12 is an important part of the present invention, and both sides of this space are By lightly applying the tip of a fishing hook or the like to the fixed abrasives 11 and 12, both sides of the tip can be polished.

As shown in FIG. 1, in this embodiment, the bearing 5
Is a so-called double-ended type, but a cantilevered type can be used by changing the method of supporting the shaft 7.

In the present invention, the length of the sides of the abrasives 11 and 12 is set to about 10 millimeters, and the amplitude of the pendulum motion of the vibrating piece 10 is adjusted to the polishing machine 1.
By making a small amount of reciprocating motion of a few millimeters, for example, about 2 millimeters, the reciprocating movement of the 1,12 portions makes it possible to easily and reliably polish the tip of a fishing hook or the like.

In addition, it is better to make the entire structure smaller so that the size fits in the human hand, and at least the vibrating piece 10 is used.
It is desirable that the other parts are formed in a size that fits in the human hand. Further, the present invention can be modified as follows.
