Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural view of the blade and the positioning assembly of the present invention.

In the figure: the cutting tool comprises a tool handle 1, scale marks 10, notches 11, an anti-slip layer 2, an oval groove 20, a blade 3, a positioning assembly 4, a 40-L-shaped plate, a threaded hole 400, a connecting column 41 and a locking assembly 5.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1 and 2, the ophthalmic scalpel of the present invention comprises a handle 1 and a blade 3, wherein the blade 3 is slidably connected to the handle 1 and is located inside the handle 1; the anti-skidding layer 2 is wrapped on the handle of a knife 1, a notch 11 is processed on the handle of a knife 1 along the length direction, the afterbody fixedly connected with locating component 4 of blade 3, the last locking Assembly 5 that can dismantle of locating component 4 is connected with. As shown in figure 1, the antiskid layer 2 is coated on the left half part of the cutter handle 1, the notch 11 is machined in the front surface of the right half part of the cutter handle 1, and the positioning component 4 penetrates through the notch 11 and is fixedly connected with the tail part of the blade 3.

The tool handle 1 is provided with scale marks 10. As shown in fig. 1, the scale mark 10 is formed on the front surface of the right half of the shank 1 and is located on the upper edge of the front surface; the zero scale line of the scale mark 10 is positioned at the right end of the tool shank 1. The length of the blade 3 extending out of the knife handle 1 can be conveniently adjusted by referring to the scale marks 10.

The anti-skid layer 2 is made of rubber. The friction between the hand and the scalpel is increased through the rubber, and the risk of slipping of the scalpel is reduced. In addition, the rubber has elasticity, and the comfort of holding the scalpel by hands can be improved.
