Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement of a kitchen knife polishing tool for home use in which a polishing rod of new ceramics is attached to a handle.

(Prior Art) A conventional product of this type has a cavity inside a handle in which an elongated polishing member is slidably mounted in the front-rear direction, and a slit is provided in the longitudinal direction of the circumferential surface of the handle to combine with the polishing member. The knob is pushed out from this slit, and when used, the knob slides forward to pull out the polishing member, and when not used, the knob slides backward to slide the polishing member inside the handle. there were.

(Problems to be solved by the present invention) The conventional product is as described above, and the new ceramics used as the polishing member is vulnerable to impact, and if the polishing rod is accidentally dropped during use, the polishing rod will be separated from the handle. It broke at the base of the product and could not be reused, so there was no choice but to discard the entire product and purchase a new one.

It is an object of the present invention to provide a product in which a handle can be continuously used by easily replacing a new polishing rod even if the polishing rod is broken.

(Means for Solving the Problem) According to the configuration of the present invention, an insertion hole 2 having a circular cross section is bored in the longitudinal direction from the front surface of a handle 1 integrally formed of an elastic material, to the middle of the handle 1, A slender cylindrical polishing member 3 made of new ceramics is inserted into the insertion hole 2 so as to be freely inserted and removed, and the polishing member 3 is inserted into the insertion hole 2 and applied to the insertion end of the polishing member 3 in use. In order to push the polishing member 3 slightly forward from the position in use, a guide hole 4 into which an extruding rod for pushing the polishing member 3 is inserted extends from the outside of the handle 1 to the innermost portion of the insertion hole 2, and the guide hole is formed. The handle 1 is characterized in that the handle 1 is also provided with a room space continuous with the guide hole 4 so that the push rod can move in the longitudinal direction of the handle at least by pushing the polishing member 3 a little.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows the first embodiment, in which the handle 1 is made of an elastic material such as an elastomer resin or synthetic rubber, and is elongated.
The collar part 5 is formed in the upper part. This is to protect the hand so that the blade edge does not hurt the hand when sharpening the knife.

An insertion hole 2 having a circular cross section is bored from the front surface (upper surface in the drawing) of the handle to the middle of the handle, and a part of a slender cylindrical polishing member 3 made of new ceramics is inserted therein. Furthermore, a guide hole 4 is formed from the rear surface (lower surface in the drawing) of the handle 1 to the insertion hole 2. The diameter of this guide hole 4 is the insertion hole 2
Is formed smaller than.

FIG. 2 shows a second embodiment, in which the guide hole 4 is bored from the side surface of the handle 1 and the depth thereof reaches at least near the central axis of the insert hole 2, and the guide hole 4 extends in the length direction of the handle. It is preferable to have a length of about 1.5 cm from the innermost part to the front rather than the innermost part. The width is slightly larger than the diameter of the extruding rod for extruding the polishing member.

The extruding rod is preferably a metal round rod, and its diameter is smaller than that of the polishing member 3.

(Operation / Effect) With a knife knife polishing tool in which a slender new ceramics polishing member is attached to the tip of the handle as in the present invention, if the polishing member 3 is broken, it breaks at the root part, so With the product, the broken part left inside the handle cannot be pulled out with fingers.

In order to push the polishing member 3 slightly forward from the position in use by applying the polishing member 3 inserted into the insertion hole 2 to the insertion end of the polishing member 3 in use, the push rod for pushing the polishing member 3 forward. A guide hole 4 into which the insert is inserted extends from the outside of the handle 1 to the deepest part of the insertion hole 2, and the push rod can move inside the guide hole 4 in the longitudinal direction of the handle at least by pushing the polishing member 3 a little. As described above, the space that is continuous with the guide hole 4 is also provided in the handle 1. Therefore, when the polishing member 3 is broken at its root, a separate extruding rod is inserted into the guide hole 4 and the polishing member 3 is pushed out a little forward, so that the portion buried inside the handle protrudes. The broken polishing member 3 remaining inside the handle 1 can be pulled out by pinching the portion with a fingertip and can be replaced with a new polishing member.

Claims (1)

[Scope of utility model registration request] 1. A handle 1 which is integrally formed of an elastic material.
From the front surface of the shank, an insertion hole 2 having a circular cross section is formed halfway in the handle 1, and a slender cylindrical polishing member 3 made of new ceramics is inserted into the insertion hole 2 so as to be removable. In order to push the polishing member 3 slightly forward from the position in use by applying it to the insertion end of the polishing member 3 inserted in the use state, the guide hole 4 into which the push-out rod for pushing the polishing member 3 is inserted. Guides from the outside of the handle 1 to the innermost part of the insertion hole 2, and guides the inside of the guide hole 4 so that the pushing rod can move in the longitudinal direction of the handle at least by pushing the polishing member 3 a little. A knife polishing tool characterized in that a space which is continuous with the hole 4 is also provided in the handle 1.
