Skin repair knife structure

This creative department is related to the dressing tools used for decoration, especially the structure of a skinning knife.

As shown in FIG. 7 , the utility model is a utility model for the decoration of the knives, which is mainly composed of a body 91 and a blade 92. The blade 92 is oppositely disposed on the body 91 and faces one of the bodies 91. A cutting section 93 is formed on the side of the cutting section 93, and the cutting section 93 defines a cutting edge 94 along one side edge of the cutting direction, by arranging the body 91 over a panel 95 to be trimmed. By pushing the body 91 along the cutting direction by force application, the blade 94 of the blade 92 on the body 91 can cut the excess protruding paper 96 to achieve the effect of skinning.
The conventional use of the dermabrasion knife in practical use is by a first abutting surface 911 on the body 91, and the cutting section 93 of the blade 92 is perpendicular to the first abutting surface 911. The abutting surface 931 can be relatively opposed to the end angular position on the plate member 95 so that the scalpel can be slid along the end angle of the plate member 95; however, due to the first abutment of the body 91 The surface 911 and the second abutting surface 931 of the cutting section 93 of the blade 92 are all a flat surface. Therefore, when the conventional trimming utility knife is disposed across the end angle of the plate member 95, as shown in FIG. The second abutting surface 931 of the cutting edge 93 of the blade 92 will also abut against the end angle side of the plate member 95 with its largest area, resulting in a large friction area, resulting in the user actually moving. In use, it is not only more labor-intensive but also affects the smoothness of the paper 96 in the feeding process, and reduces the efficiency of the skinning work, and since the blade 92 is made of a relatively hard material, when the blade 92 is Plate 95 When the contact area is too large, the plate member 95 is also prone to being damaged due to excessive friction.
In view of this, how to improve the above problems is the primary subject of this creation. Therefore, the creators of this case have finally produced this creation after continuous hard work and trials.

The main purpose of this creation is to provide a scalpel structure which is easier and less laborious to use, and can effectively improve the smoothness of the paper during the feeding process and reduce the wear of the blade by the blade.
For the purpose of the foregoing, the present invention provides a dermatological knife structure for cutting a embossed portion of a tissue attached to a panel, the dermatological structure comprising:
a body having a first abutting surface opposite to a side surface of the plate member and a bonding surface perpendicularly contacting the first abutting surface;
