Multi-function skinning knife structure

This creation is about a multi-functional scalpel structure. As long as it is applied to the general surface of the workpiece, it can be repaired and smoothed through the structure of the body and the flattening blade. In addition to the straightening work, it is more suitable for the practical value of the whole.

According to the general product, in order to present the appearance and touch of the material different from its own material, it is often used to attach various colors, patterns and textures to the surface of the product, which can enhance the texture and style of the product.

In order to achieve a good fit quality, the size of the leather is usually slightly larger than the product attachment surface, so that the edge of the product attachment surface is slightly protruded after the decoration is applied. Forming the so-called "edge", and then using the utility knife or a special leather knife to repair the edge beyond the edge, that is, complete the decoration of the skin.

For the repairing operation of the surface of the workpiece surface, the manufacturer has developed a scalpel as disclosed in the aforementioned Patent No. 102,216, 392, which is mainly provided with a body suitable for hand-held operation, and a slight depression is formed on one side of the body. The sipe and the locking bolt hole are preset on the sipe, so that the customized taming blade is locked on the sipe, and the taming blade protrudes slightly on the side of the body, so that the dermatological blade corresponds to A V-shaped knife is respectively formed at both ends of the side edge of the body The mouth and the blade part are then attached to the surface of the workpiece skin by the side of the body and are operated and moved, so that the edge of the blade of the skinning blade can be cut off from the edge of the skin to complete the trimming operation.

However, the structure of the derrick knife disclosed above has the advantages of simple structure and convenient operation, but because the body volume is not large, and it is a simple rectangular body, the flexibility in the hand-held operation is obviously insufficient, and Limited by the combination of the side of the body and the blade, so that it can only be trimmed in a straight shape. If the workpiece has an arc-shaped end angle, then the straight skin is repaired. Knife is faced with difficulties in operation, and even needs to be trimmed by hand, which seriously affects the convenience of its work, and is more likely to affect its overall work quality. It is necessary to try to solve the improvement.

In view of the fact that there are some problems in the hand-held knives, such as the lack of hand-held operation flexibility, and the problems and disadvantages that can only be caused by the straight trimming operation, the creator has specially developed and developed the flexibility and implementation object of the control. Can be further improved, according to the research and creation of the creation of the multi-functional scalpel structure.

The knives of the creation are mainly constructed by pivoting two different types of base bodies to adjust the angle of relative relationship to give greater flexibility and stability to the hand-held operation. The different types of side edges of each substrate are planned so that when the skin-removing blade sets are set on different substrates, different types of decorative skins can be used to repair the operator.

The multi-function derrick structure of the present invention is selectively mounted on different substrates through the two-piece base pivot structure body of different types, in addition to the relative angle adjustment of the two-piece base body. To make it more flexible and easy to handle, it is better to choose different functional modes of straight leather or curved skinning according to the actual operation requirements. For better practical value.
