[0019] Example, by Figure 1-5The utility model comprises a U-shaped seat 1, wherein two folding knives are installed inside the U-shaped seat 1, wherein the folding knives are composed of a knife seat 2 and a cutting knife 3, wherein the cutting knife 3 is movably connected to one side of the U-shaped seat 1 through a damping rotating shaft, and a rotating rod 6 is penetrated and connected to the front side of the U-shaped seat 1, and the rotating rod 6 penetrates the knife seat 2, and the outer end of the rotating rod 6 is processed with two threads in opposite directions, and the two knife seats 2 are respectively connected to the rotating rod 6 through two threads in opposite directions, and a rotating wheel 7 is fixedly connected to each other at both ends of the rotating rod 6, and a bolt head 11 is fixedly connected to one side of the U-shaped seat 1, and a handle 12 is threadedly connected to one side of the U-shaped seat 1 through the bolt head 11. When two folding knives are unfolded at the same time, pathological materials of a specified thickness can be cut out at one time, which is more efficient and more accurate. When one folding knife is folded, the remaining folding knife can be used as an ordinary single-knife cutting, which is more applicable.

[0020] A slider 8 is fixedly connected to the inner wall of the U-shaped seat 1, and a slide groove 9 is provided on the side of the knife seat 2 away from the cutting knife 3. The slider 8 passes through the slide groove 9, and the outer end of the slider 8 is adapted to the inside of the slide groove 9. The slider 8 and the slide groove 9 cooperate to limit the knife seat 2 when it moves.

[0021] An arrow 5 is processed on one side of the top of the knife seat 2 close to the U-shaped seat 1, and two scale lines 10 are processed on the top of the U-shaped seat 1. The two scale lines 10 are symmetrically distributed about the central axis of the U-shaped seat 1. The arrow 5 points to the scale line 10, which can help to know the distance between the two folding knives.

[0022] The U-shaped seat 1 and the rotating rod 6 are movably connected, and the connection between the U-shaped seat 1 and the rotating rod 6 is interference fit. The outer end of the rotating wheel 7 is processed with anti-skid patterns. The interference fit of the U-shaped seat 1 and the rotating rod 6 can prevent the rotating rod 6 from rotating at will, thereby improving the stability of the position of the folding knife. The anti-skid patterns can increase the friction force on the surface of the rotating wheel 7, and the rotating wheel 7 can be rotated more conveniently.

[0023] The bottom of the knife seat 2 is provided with a notch 4 , and the notch 4 can more conveniently pull out the cutting knife 3 stored in the knife seat 2 .

[0024] Working principle:

[0025] When cutting a certain length of pathological material, the two folding knives can be unfolded and the distance between the two folding knives can be adjusted. When adjusting, the rotating wheel 7 can be pinched with fingers and rotated, and the rotating wheel 7 drives the rotating rod 6 to rotate. Since the two knife seats 2 and the rotating rod 6 are connected by two threads in opposite directions, the two knife seats 2 will move away from or towards each other along the rotating rod 6 when the rotating rod 6 rotates. When adjusting the position of the folding knives, the distance between the two folding knives can be judged by the scale line 10 on the U-shaped seat 1 pointed to by the arrow 5. After the positions of the two folding knives are adjusted, the pathological material of the required thickness can be cut at one time by the two cutting knives 3 by holding the handle 12.
