[0039] Working principle of the present invention: A top push rod 112 is fixed to the top of the outer sleeve 113, and an upper bolt 105 is fixed to the middle of the rear disc 104. The horizontal push frame 111 is sleeved outside the top push rod 112. A vertical adjustment frame 106 is fixed to the middle of the top push rod 112.

The middle cutting support 206 is fixedly connected to the bottom of the middle outer sleeve 113. The cutting blade 207 is installed in the middle of the middle cutting support 206, the left cutting support 208 and the right cutting support 209. In this way, as the driving rotating shaft 201 and the middle rotating square shaft 205 rotate, the cutting blade 207 can rotate. Pushing the horizontal push frame 111 back and forth can change the position of the outer sleeve 113 on the middle cylinder 107, so as to adjust the distance between the cutting blades 207. During the process of cutting the coil material, it is convenient to adjust. An outer support frame 301 is fixed to the front end of the bottom support frame 110.

Left telescopic rods 303 and right telescopic rods 304 are respectively fixed to both sides of the outer support frame 301. During the rotation of the coil material cutting, the front parts of the left bottom bent plate 306 and the right bottom bent plate 309 are pushed up by the left telescopic rod 303 and the right telescopic rod 304, so that the distance between the center of the coil material and the driving rotating shaft 201 gradually becomes closer. In this way, the cutting blade 207 completes the cutting of the coil material. When the main distance induction switch 203 and the sub-distance induction switch 204 detect the closest distance, the cutting is completed at this time. The front ends of the middle cutting support 206 and the right cutting support 209 are opened, so that the coil material falls from the front end. After the coil material falls, it enters the middle of the middle cutting support 206 and the right cutting support 209 from the bottom of the outer support frame 301, and continues to cut the coil material. At this time, the front ends of the middle cutting support 206 and the right cutting support 209 gradually rise, so that the cutting blade 207 gradually cuts the coil material, and the driving rotating shaft 201 and the coil material always maintain a stable approaching speed.
