Description

Carving knife structure

The invention relates to a carving knife structure, in particular to a carving knife structure, which is provided with a body, a limiting member, an clamping member, a cutter body and a fixing member, and the cutter body is also sandwiched by the clamping member except by the fixing member. The joint structure between the cutter body and the clamping member is more stable, and the cutter system is not disengaged from the clamp member.

According to what we have previously known, the conventional carving knife structure, such as Taiwan Patent Application No.: 86220680, patent name: multi-purpose fine engraving tool knife, the patent structure is: a multi-purpose fine carving tool knife, tied An end sleeve of a handle 1 is sleeved with a hollow sleeve, and the sleeve head is further provided with a rotary cutter 6 having a tip end which is rotatably rotatable against the end of the handle 1; wherein the circumference of the rotary cutter 6 is Formed as an upright polygon, and the outer surface of the ferrule is appropriately formed with a ring groove 71, and the opposite side edges of the ring groove 71 are respectively provided with a through slit 72 corresponding to the polygonal side wall of the knives 6 . Another spring clip 8 can be inserted into the ring groove 71. By changing the position of the spring clip 8 relative to the ring groove 71, the cutting blade 72 can be inserted into the slit 72 to restrain the rotation thereof, or It is separated from the slit 72 and placed on the ring groove 71, allowing the rotary cutter 6 to be freely rotated.

However, the missing structure of this conventional carving knife is:

1. Please supplement the first and second figures. The tool head 3 is inserted into the nip of the clamp 2 Or in the circular hole groove 23, but there is no fixing member between the tool head 3 and the nip 22 or the circular hole groove 23 for fixing the tool head 3 in the nip 22 or the circular hole groove 23, the tool head 3 and the clamp The two bases are only sandwiched by the frictional force, and the tool head 3 may be disengaged from the slit 22 or the circular hole groove 23 due to the fact that there is no positive engagement, which is less secure.

2. The head 4 is screwed to the external thread 20 of the holder 2. The internal thread 11 of the handle 1 is also screwed to the external thread 20 of the holder 2. Generally, the operator's hand should contact the beam head. 4, at the outer peripheral surface of the handle 1, when the hand applies a force to operate the engraving knife structure, the hand exerts a force on the handle 1 and the head 4 when there is a rotational force, so that the beam head 4 and the holder 2 may be Or the automatic screwing of the handle 1 and the holder 2 is missing.

In view of the lack of the structure of the engraving knives in the above-mentioned conventional patent case, the inventors have years of experience in manufacturing related industries, and finally have a product that can solve the drawbacks of the engraving knife structure.

The tool head and the holder between the engraving knife structure The utility model only relates to the friction force, and the tool head system may be undetached from the clamping seat because it is not properly engaged, and the invention is related to the structure of the engraving knife. The structure of the engraving knife is provided with the body and the limiting member. The clamping member, the cutter body and the fixing member are not only limited by the fixing member but also sandwiched by the clamping member, and the joint structure between the cutter body and the clamping member is more stable, and the cutter system is not clamped The parts are separated and safe.

An engraving knife structure comprising: a body The first sleeve portion and the first screw portion are provided; the second sleeve portion is provided with the second sleeve portion to fit the first portion a set of joints, the restricting member is provided with a receiving portion and a first tapered surface; a clamping member is received through the receiving portion, and the clamping member is provided with a second screwing portion for the first The screwing portion is screwed, and the other end of the clamping member is provided with a head portion and a second tapered surface. The second tapered surface is abutted against the first tapered surface, and the clamping member is provided with an clamping portion and at least a first fixing groove; a knife system is disposed at the clamping portion, the knife system is provided with a second fixing groove to be opposite to the first fixing groove; at least one fixing member is fixed at the first fixing groove, the fixing The part is semi-convexly exposed at the clamping portion, so that the knife system can pass through the gap between the fixing member and the clamping portion, the knife system is provided with a second fixing groove, and the second fixing groove is a positive fixing member, the clip After the two side faces of the device are close to each other, the second fixing groove is restricted by the fixing member and the two sides of the blade body are sandwiched by the two sides of the clamping portion, so that the blade system is fixedly clamped at the clamping portion without being clamped The parts are separated.

The knife system is clamped at the clamping portion of the clamping member After the user rotates the clamping member such that the second screwing portion of the limiting member is screwed inwardly with the first screwing portion of the body, the second tapered surface is restrained by the first cone of the limiting member. The pressing of the surface is pressed against, and the two sides of the clamping portion are close to the two sides of the clamping body, and the fixing member is disposed at the first fixing groove and the second fixing groove, so that the knife system is not clamped The workpiece phase is disengaged, and the cutter body is sandwiched by the clamping portion except by the fixing member. The joint structure between the cutter body and the clamping member is more stable, and the cutter body is safer in use. The clips are disengaged. When the hand is in contact with the body and the limiting member, when the limiting member rotates relative to the body, the first tapered surface of the limiting member is less likely to drive the second tapered surface of the clamping member, so that the clamping member The rotation, that is, the second screwing member, which is impossible to drive the clamping member, and the first screwing portion of the body are screwed apart, and the probability of the screwing between the clamping member and the body is greatly reduced.

In order to make the members of the Board and those skilled in the art fully effective in the present invention The structure and composition of the present invention are described with reference to the drawings and the drawings, and the following description is only for explaining the embodiments of the present invention, and is not intended to impose any form limitation on the present invention.
