Description

Trimming knife improved structure

This creation is about an improved structure of the trimming knife, which is especially suitable for woodworking or decorating users.

In general, after the production of the plate products, in order to avoid the burrs generated by the edges, or the sharp right angles to injure others, it is necessary to trim the right angles and edges during the processing; in addition, in order to make The surface of the sheet product achieves a good touch and aesthetic effect, and various types of accessories are added to the surface. At this time, trimming tools are also required for cutting and trimming.

However, the conventional trimming tools are mostly formed by forming a metal knife bed and a blade integrally or placing the metal blade on a trimming tool body, and both of them are on both sides of the head and the tail. The disadvantage is that the blade angle and the edge direction cannot overcome the veneer. When trimming, the problem of burrs or fiber tears due to the irregular back-grain of the veneer, and in the case of prolonged use, it is easy to cause the blade to be not sharp and rust, and most of the time The group of trimming tools has been replaced; the loss and environmental protection problems have been increased; in addition, the hardness of the plate products made of different materials is different, and cutting with only one metal blade can not maximize the benefits.

In view of this, the author can provide a modified blade with a different type of blade for more efficient trimming of different materials of the skin or thin sheet; in the environmental protection concept, increase the output value, Reducing the rate of wear and tear is a painstaking research and design system. In order to provide consumers with the use of the consumer, this is the creative motive of the creative research.

The main purpose of this creation is to provide a trimming knife improved structure that facilitates the replacement of different types of blades to more effectively trim the skin or sheet of different materials.

In order to achieve the above object, the present invention comprises: a knife holder having an induction groove and at least one sipe on one side, the at least one sipe being a through-inducing groove; at least one blade detachably correspondingly disposed on the sipe, the end of which is exposed a lower edge of the sipe; and an outer cover whose outer edge is closed along the lower edge of at least one sipe to cover the knives.

The trimming blade has a modified structure as described above, and the blade end is a one-way sawtooth or a single-sided sharpening.

In the improved structure of the trimming knife as described above, the tool holder and the outer cover are further provided with a plurality of corresponding screw holes, which are screwed by screws.

The trimming knife has an improved structure as described above, and the material of the holder is any one of plastic, metal or hard wood.

The improved structure of the trimming knife as described above, the material of the outer cover may be any of plastic, metal or hard wood.

The trimming blade has an improved structure as described above, and the blade holder fixes the blade by a predetermined screw hole and a screw.

The outstanding advantages of this creation over the prior art are:

1. Trimming the skin or sheet of different materials through different blades that are easy to replace.

2. With the replaceable tool, it can effectively overcome the problem of burrs or fiber tears when the veneer is trimmed. Moreover, if the blade is not sharp or rusted due to excessive use time, only the blade needs to be replaced. There is no need to replace the entire set of trimming tools.
