When it continues to move to the appropriate position, the second spring push rod will push the tooth plate to automatically reset. The vibration generated will make the lubricating oil on the surface of the rotating wheel and the tooth plate evenly distributed, preventing the accumulation of lubricating oil from affecting the normal use of the gear and the tooth plate.

[0025] In summary, the present invention has the following beneficial effects:

[0026] When in use, by starting the height adjustment component and running it to one side, it will drive the spacing adjustment component to run, so that the spacing adjustment component can adjust the spacing between the two sets of tools.

[0043] Brief description of the use process: When in use, by starting the height adjustment component 3 and running it to one side, the spacing adjustment component 2 will be driven to run, so that the spacing adjustment component 2 adjusts the spacing between the two sets of tools.

[0046] The spacing adjustment component 2 includes a support ring 214, which is slidably connected to the surfaces of the two groups of sliding columns 322, and a turntable 213 is rotatably connected inside the support ring 214; four groups of positioning holes 212 are opened on the upper end of the turntable 213, and mounting shells 205 are welded on both sides of the inner wall of the turntable 213, and a third rotating rod 208 is welded inside the mounting shell 205. The middle part of the surface of the third rotating rod 208 is rotatably connected to the rotating plate 206, and torsion springs 207 are sleeved at both ends of the third rotating rod 208, and both ends of the torsion spring 207 are connected between the mounting shell 205 and the rotating plate 206 through spring fixings; a fixing ring 203 is welded at one end of the first sliding shell 309, and a push plate 204 is welded on one side of the fixing ring 203, and a second connecting plate 209 is welded on one side of the surface of the first sliding shell 309, and a positioning rod 211 is slidably connected inside the second connecting plate 209, and the positioning rod 211 surface The face cover is provided with a telescopic spring 210, and both ends of the telescopic spring 210 are connected between the positioning rod 211 and the second connecting plate 209 through spring fixings, and a hollow shell 215 is welded at the lower end of the turntable 213; the four corners of the top of the hollow shell 215 are bolted with second spring push rods 216, and the piston ends of four groups of second spring push rods 216 are commonly bolted with a rectangular plate 222, and the lower end of the rectangular plate 222 is slidably connected with two groups of tooth plates 220, and a plurality of groups of first inclined panels 217 are welded on one side of the tooth plate 220, and a second inclined panel 218 is welded on the bottom of the hollow shell 215, and the first inclined panel 217 and the second inclined panel 218 are slidably connected. A gear 219 is meshed and connected between the two groups of tooth plates 220, and the gear 219 is welded to one end of the first sliding shell 309, and one end of the two groups of tooth plates 220 can be detachably connected with a cutter 221.

[0047] Brief description of the use process: When the motor 305 runs to one side, it will drive the sliding rod 304 and the first sliding shell 309 to rotate. Since a rotating shaft 306 is provided on one side of the motor 305, the rotation of the first sliding shell 309 will drive the first connecting plate 308 and the tension spring 307 to rotate on the surface of the rotating shaft 306. The tension spring 307 can apply a pulling force to the components below to adapt to the weight of the components. While the rotating column 310 and the extrusion rod 311 follow the rotation of the first sliding shell 309, the extrusion rod 311 will move inside the extrusion groove 324. At this time, the extrusion rod 311 will move from the position of the third slide groove 320 to the position of the second slide groove 319. At this time, the first sliding shell 309 will drive the fixing ring 203 and the push plate 204 to rotate counterclockwise. When the push plate 204 passes the rotating plate 206, the rotating plate 206 will be rotated by the third rotating rod 208, so that the push plate 204 can pass smoothly, so that the turntable 213 will not be driven to rotate inside the support ring 214. At the same time, the gear 219 will also rotate with the first sliding shell 309, and the gear 219 will drive the two sets of tooth plates 220 and the cutter 221 to move to both sides. During the movement, the first inclined plate 217 on one side of the tooth plate 220 will be squeezed by the second inclined plate 218. Since the surface is an inclined surface and is made of tempered glass, when the first inclined plate 217 is squeezed by the second inclined plate 218, the second spring push rod 216 will be used to move. When the tooth plate 220 continues to move, the second spring push rod 216 will push the tooth plate 220 to automatically reset. The vibration generated when the first inclined plate 217 contacts the hollow shell 215 will make the lubricating oil between the tooth plate 220 and the gear 219 more evenly distributed, thereby completing the spacing adjustment of the two sets of cutters 221. In addition, since both sides of one end of the positioning rod 211 are set as inclined surfaces, when the second connecting plate 209 drives the positioning rod 211 to rotate with the first sliding shell 309, the inclined surface squeezes the inner wall of the positioning hole 212, and moves upward and rotates with the first sliding shell 309. When the appropriate position is reached, it is automatically positioned inside the positioning hole 212 to prevent the turntable 213 from rotating arbitrarily inside the support ring 214. When the direction of the two sets of cutters 221 needs to be changed, the motor 305 is operated clockwise, and the motor 305 When the two sets of cutting tools are rotated, the telescopic spring 210 pulls the positioning rod 211 to reposition it in the new positioning hole 212. ...The extrusion rod 311 will move from the extrusion groove 324 at the upper end of the inner wall of the annular shell 317 to the extrusion groove 324 at the lower end, and then the first sliding shell 309 will move down on the surface of the sliding rod 304, thereby adjusting the distance between the cutter 221 and the workpiece. When the cylinder 302 is running, it will drive the cutter 221 to move down for die cutting.
