A limiting mechanism 7 is installed at the bottom of the mounting frame 4. The limiting mechanism 7 can limit the adjustment mechanism 6, so that after the adjustment mechanism 6 adjusts the position of the tool holder 5, the tool holder 5 will not be easily affected by the adjustment mechanism 6 and will appear position deviation. The inner cavity of the mounting frame 4 is fixedly connected with a positioning block 17, and a positioning groove 16 is provided at the bottom of the tool holder 5. The number of the positioning groove 16 and the positioning block 17 are both four. The surface of the positioning block 17 is slidably connected with the inner wall of the positioning groove 16. Under this effect, the position of the tool holder 5 can be made more accurate, thereby avoiding the tool holder 5 from being out of position due to the large force when chamfering the plastic product after the tool holder 5 is adjusted. In order to solve the problem of displacement, the stability of the tool holder 5 is effectively improved. Guide blocks 8 are fixedly connected on both sides of the inner cavity of the shell 1. The guide blocks 8 are of wedge-shaped structure design. The bottom of the shell 1 is connected with a guide shell 9. The bottom of the inner cavity of the guide shell 9 is of inclined structure design. One side of the guide shell 9 is connected with a mounting shell 10. The inner cavity of the mounting shell 10 is slidably connected with a collecting box 12. One side of the collecting box 12 penetrates to the outside of the mounting shell 10 and is slidably connected to the inner wall of the penetration. With the cooperation of the guide blocks 8 and the guide shell 9, the waste chips generated during chamfering can be discharged into the interior of the mounting shell 10 through the guide shell 9, so that the waste chips can fall into the interior of the collecting box 12, which is convenient for collecting the waste chips. An air outlet is provided on one side of the mounting shell 10 Slots 11, the number of air outlet slots 11 is several, under this effect, the fan inside the shell 1 can be discharged through the air outlet slots 11 when blowing air, and the waste chips are conveniently moved under the action of the air, so as to prevent the debris inside the shell 1 from floating randomly inside, and effectively improve the waste collection effect of the device. A magnet 13 is embedded at the bottom of the inner cavity of the installation shell 10, and the collection box 12 is made of iron. The magnet 13 is used in conjunction with the collection box 12, and under this effect, it is convenient to limit the collection box 12, so that the collection box 12 will not easily shift its position when collecting waste chips. A blocking plate 14 is fixedly connected to one side of the inner cavity of the installation shell 10, and the bottom of the blocking plate 14 is slidably connected to the top of the collection box 12.Under this effect, the collection box 12 is squeezed and limited by the blocking plate 14 and the bottom of the inner cavity of the mounting shell 10, which effectively improves the stability of the collection box 12 during movement and use.

[0025] The adjusting mechanism 6 comprises a rotating rod 61, the top of which is rotatably connected to the bottom of the tool holder 5, and the other end of the rotating rod 61 passes through the bottom of the mounting frame 4 and is slidably connected to the inner wall of the penetration point. A toggle plate 62 is fixedly connected to the lower surface of the rotating rod 61, and the top of the toggle plate 62 is slidably connected to the bottom of the mounting frame 4. A movable groove 63 is provided on one side of the bottom of the mounting frame 4. Under this action, when the toggle plate 62 is rotated to the movable groove 63, the squeezing of the tool holder 5 can be released, and the rotating rod 61 can drive the tool holder 5 to rotate, thereby adjusting the tool on the surface of the tool holder 5. After the adjustment is completed, the toggle plate 62 is disengaged from the inside of the movable groove 63, and then the toggle plate 62 is rotated to one hundred and eighty degrees, so that the tool holder 5 will not rotate easily under the action of friction, and the toggle plate 62 is limited with the cooperation of the limiting mechanism 7.

[0026] The limiting mechanism 7 includes a mounting groove 71 formed at the bottom of the mounting bracket 4. The inner cavity of the mounting groove 71 is fixedly connected to a compression spring 72. The other end of the compression spring 72 is fixedly connected to a positioning shell 73. The inner wall of the positioning shell 73 is slidably connected to the surface of the toggle plate 62. Under this action, when it is necessary to limit the toggle plate 62, the positioning shell 73 can be pulled to move it to a side away from the toggle plate 62. Then, when the toggle plate 62 is adjusted to correspond to the positioning shell 73, the positioning shell 73 is released. With the cooperation of the compression spring 72, the positioning shell 73 is stuck on the surface of the toggle plate 62 to limit the toggle plate 62, so as to facilitate the limiting of the tool holder 5. The mounting groove 71 The cross-sectional shape of the inner cavity is a T-shaped structure design, under this action, the positioning shell 73 will not easily detach from the inner cavity of the mounting groove 71, effectively improving the stability of the positioning shell 73 when moving. A guide rod 15 is fixedly connected to one side of the inner cavity of the mounting groove 71, and one end of the guide rod 15 passes through the other side of the positioning shell 73 and is slidably connected to the inner wall of the penetration point. Under this action, the positioning shell 73 can be guided when it moves, thereby making the positioning shell 73 more stable when moving. The guide rod 15 is located inside the compression spring 72, and under this action, the compression spring 72 can also be guided, thereby making it more stable when compressed or rebounded.

The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0028] Working principle: First, when the tool holder 5 needs to be adjusted, the staff pulls the positioning shell 73 so that it is no longer in contact with the toggle plate 62, and then rotates the toggle plate 62 to the inside of the movable groove 63, and then moves the tool holder 5 upward, and then rotates the tool holder 5 to select a suitable tool, and then limits the tool holder 5 with the cooperation of the positioning groove 16 and the positioning block 17, and then rotates the toggle plate 62 to the positioning shell 73 again, and under the action of the compression spring 72, the positioning shell 73 limits the toggle plate 62, and then the plastic product that needs to be chamfered is installed inside the positioning mechanism 2, and then the hydraulic cylinder 3 is turned on to drive the tool holder 5 to chamfer the plastic product. During the chamfering process, the debris will fall to the bottom of the inner cavity of the shell 1 under the action of the fan inside the shell 1, and move to the inside of the collection box 12 after being guided by the guide block 8 and the guide shell 9, and the air is discharged from the air outlet slot 11. When the waste chips inside the collection box 12 need to be cleaned, the collection box 12 can be directly taken out.
