Figure 3 As shown, the buffer pad 206 is made of silicone material, and the buffer pad 206 prevents the lifting plate 204 from being damaged when it descends in the mounting plate 203;

[0029] The top of the lifting plate 204 and the outside of the guide rod 208 are fixedly connected with a pull rod 217, and the two ends of the outer wall of the lifting plate 204 are symmetrically provided with card slots 205. The bottom of the mounting plate 203 and the position near the tool 207 are hollowed out, and the lower end of the inner wall of the mounting plate 203 is movably connected to the buffer pad 206, and the inner wall of the mounting plate 203 is slidably connected to the pull rod 217, and the middle of the top of the mounting plate 203 is threadedly connected to the screw 211, as shown in FIG. Figure 3 As shown, when the screw rod 211 rotates, the threads on its surface push itself up or down;

[0030] The inner wall of the mounting plate 203 and both sides of the lifting plate 204 are slidably connected with a pressing plate 213, the tops of the two pressing plates 213 are fixedly connected with a connecting plate 218, the outer walls of the two pressing plates 213 and the side close to the lifting plate 204 are fixedly connected with an extrusion block 214, the bottoms of the two pressing plates 213 are fixedly connected with a spring 216, and the bottom of the spring 216 is fixedly connected to the inner wall of the mounting plate 203, such as Figure 3 As shown, the spring 216 pushes the pressing plate 213 upward;

[0032] The upper part 2 of the device also includes a rotating frame 201, a handle 202 is fixedly connected to one side of the outer wall of the rotating frame 201, and the inner side of the handle 202 is fixedly connected to the mounting plate 203; the lower part 1 of the device includes a bottom plate 101, a fiber placement plate 102 is fixedly connected to the middle of the top of the bottom plate 101, a connecting frame 103 is fixedly connected to one side of the top of the bottom plate 101, the upper end of the connecting frame 103 is rotatably connected to the rotating frame 201, and the top of the fiber placement plate 102 is in active contact with the mounting plate 203 and the tool 207, such as Figure 1 As shown, the bottom of the mounting plate 203 contacts the placement plate 102 to press and limit the fibers to be cut.

[0033] The working principle of this utility model:

The ball 215 cannot prevent the lifting plate 204 from moving, and the cutter 207 at the bottom of the lifting plate 204 can fall and cut the fibers below the mounting plate 203.

[0036] When adjusting the cutting force of the tool 207, the knob 212 is turned to drive the screw rod 211 to rotate and rise and fall in the mounting plate 203, so that the distance between the sleeve rod 210 and the guide rod 209 changes, and the compression degree of the spring 1 210 changes, thereby changing the force of the spring 1 210 pushing the lower lifting plate 204.
