Description

Multifunctional skinning knife improved structure

This creation is about the improved structure of a multi-function scalpel, which is mainly used for the trimming of the surface of the general workpiece. After the body and the structure of the blade, it is used in addition to the straightening work. It can better respond to the needs of the skin of the arc, and can be used to meet the operator's different hand habits to select the blade type to give the handy and convenient operation, which can greatly enhance the overall practical value.

According to the general surface decoration of the workpiece, in order to obtain a good bonding quality, the size of the decorative skin is usually slightly larger than the surface of the workpiece, so that the decorative skin can be completely covered after the decorative skin is attached. Relatively, the decorative skin slightly protrudes from the edge of the workpiece attachment surface, forming a so-called "squeezing edge", and then the special edge-repairing knife is used to remove the edge beyond the edge, that is, the fitting and trimming work of the decorative skin is completed.

For the repair work of the surface of the workpiece surface, the manufacturer has developed a special leather knives, which mainly have a body suitable for hand-held operation, and a slightly concave sipe is formed on one side of the body, and is in the sipe. The upper part is provided with a bolt hole, and the blade is fixedly locked on the sipe, and the blade is slightly protruded from the side of the body, so that the blade is respectively formed at two ends corresponding to the side edge of the body. The V-shaped blade edge and the blade surface, so that when the surface of the body is attached to the surface of the workpiece skin and is operated and moved, the blade edge of the blade can be cut off from the edge of the blade to complete the modification. Trimming work.

However, the structure of the derrick knife disclosed above has the advantages of simple structure and convenient operation. However, 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 to the assembly relationship between the side of the body and the blade, so that it can only be trimmed in a straight shape, and if the workpiece has an arc-shaped end angle, the straight scalpel will be In the face of difficulties in operation, it is even necessary to carry out trimming in a freehand manner, which seriously affects the convenience of work, and is more likely to affect the overall quality of work. 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 of the straight trimming operation, the creators have specially developed and implemented the flexibility and trimming of the control. The functionality can be further improved, and the researcher has created a multi-functional scalpel improved structure.

The leather knives of the present invention mainly adopt different shapes of flat and curved sides on the two sides of the main body, and a pair of set holes are respectively arranged on the near two sides, and are matched with the cutting edges of different parts on both sides of the blade. And the blade plan, so that when the blade selection lock set is set on the lock hole of different sides, it can be formed into two different types of flat trimming and arc trimming.

The multifunctional scalpel structure of the present invention is designed through the locking hole of the main body, and is matched with the blade edge and the blade surface on different sides of the blade, so that it can be selectively mounted on different sides of the body by using a blade, except that the flat can be implemented. In addition to the straight-line work, it is more important to give the flexible and smooth arc trimming function according to the different hand habits of the operators, so as to greatly enhance the overall practical value.

Regarding the structural composition, technical means and efficacy of this creation, we will further elaborate on the following examples with reference to the following: Please refer to Figures 1~7 to illustrate the first preferred embodiment of the creation. For the right-handed operator's leather knives, as shown in the figure, the derricks are structurally composed mainly of: a body (10), which is a block suitable for hand-operated operation, and has a flat surface on one side. Straight state, and the other opposite side edge surface is in a continuous arc shape, which is located on the near side of the body (10) A right side assembly hole (11) (12) and a left side assembly hole (13) (14) are provided for selective assembly of the optional blade (20); and a blade (20), A U-shaped slot (21) (22) is provided on one side of the hole (11) (12) corresponding to the right side of the body (10), so that the blade (20) can be selectively assembled. The right side of the body (10) is provided with a hole (11) (12) or a left side set hole (13) (14), and the adjustment relationship between the blade (20) and the body (10) is adjusted, and the blade (20) A cutting edge (23) (24) is formed on each of the right end portions of the U-shaped groove (21) (22), and a blade surface (231) is formed on one side of the cutting edge (23) (24) ( 241), on the left side of the U-shaped groove (21) (22) of the blade (20), the partial cutting from the front end to the front U-shaped groove (21), so that the front end of the blade (20) becomes a corner portion, and another notch (25) is formed at a predetermined position of the slot wall of the U-shaped slot (21), and a blade surface (251) is formed on one side of the blade (25).
