[0033] In this embodiment, the first drive motor 201 drives the disc 202 fixedly connected by the coupling to drive the stop block 203 to rotate. At this time, the stop block 203 slides inside the limit sleeve 403, and at the same time pulls the movable frame 4 to drive the guide rod 404 to perform a linear sliding motion, so that the guide rod 404 slides inside the guide groove 302, and then pulls the shear plates 3 to separate from each other, so that the material to be cut can be placed between the two shear plates 3. When the disc 202 rotates one circle, the guide rod 404 slides inside the guide groove 302 again, which can drive the two shear plates 3 to move relative to each other, cut the material, and facilitate use by the staff.

[0034] Example 2

[0035] like Figure 1-6As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a movable groove 206 is provided at the front end of the movable plate 2, the number of shear plates 3 is two groups, and the two ends of the shear plates 3 are fixedly connected with rotating shafts 303, and the shear plates 3 are rotatably connected to the inside of the movable groove 206 through the rotating shafts 303, and a sliding groove 205 is provided inside the fixed block 204, and the limiting sleeve 403 and the movable frame 4 are fixedly connected with a connecting rod 401, and the upper and lower ends of the connecting rod 401 are fixedly connected with a slider 402, and the slider 402 is slidably connected to the inside of the sliding groove 205, the stopper 203 is slidably connected to the inside of the limiting sleeve 403, and the guide rod 404 is slidably connected to the inside of the guide groove 302.

When the stop block 203 is driven to rotate by the disc 202, it can slide inside the limiting sleeve 403, and at the same time drive the movable frame 4 to drive the guide rod 404 to make a linear sliding motion, so that the guide rod 404 slides inside the guide groove 302, and then pulls the shear plates 3 to separate from each other, so that the material to be cut can be placed between the two shear plates 3. When the guide rod 404 slides inside the guide groove 302 again, it can drive the two shear plates 3 to move relative to each other, cut the material, and facilitate the use of the staff.

When the threaded rod 501 rotates, the movable plate 2 can make a sliding motion under the action of the threaded rod 501 threadedly engaging with the inside of the threaded groove 208, thereby facilitating the staff to adjust its position, further improving the practicality of the equipment, and facilitating the use of the staff.
