[0020] An easily adjustable cutting device for processing multi-core tubes, such as... Figures 1 to 3 As shown, the system includes a mounting base 1, with a support frame 2 fixedly mounted on the upper exterior of the mounting base 1. The front end of the support frame 2 is hollow, and two support rollers 3 are arranged inside the support frame 2, positioned close to each other. The support rollers 3 are movably mounted inside the support frame 2 by bolts, and their surfaces extend to the outside of the support frame 2 after installation. The upper end of the mounting base 1 has a folded structure and an adjustment hole 4 is provided on its surface. A rotating handle 5 is inserted into the adjustment hole 4. An adjustment bracket 6 is provided above the support frame 2, and the overall length of the adjustment bracket 6 corresponds to the extension length of the support frame 2. Separate positioning brackets 14 are fixedly mounted on the outer walls of both sides of the top of the mounting base 1, and a positioning shaft 15 is fixedly inserted between the two corresponding positioning brackets 14.

[0021] The adjusting bracket 6 has a groove on one side of the mounting base 1, the size of which corresponds to the size of the top side of the mounting base 1. Both ends of the adjusting bracket 6 on the side of the mounting base 1 have socket holes 10. The internal size of the socket holes 10 corresponds to the outer diameter of the positioning shafts 15. After the adjusting bracket 6 is snapped into the front side of the mounting base 1, the two positioning shafts 15 pass through the corresponding socket holes 10. After the adjusting bracket 6 is movably installed on the front side of the mounting base 1 through the two positioning shafts 15, it can move up and down.

[0022] The top of the adjusting bracket 6 is fixedly installed with a docking slot 7 for positioning. The lower end of the rotating handle 5 passes through the adjusting socket 4 and extends to the bottom of the adjusting socket 4 and is inserted into the interior of the docking slot 7. After the rotating handle 5 is pressed into the interior of the docking slot 7, it will push the entire adjusting bracket 6 down.

[0023] The front end of the adjusting bracket 6 has an internal mounting slot 8. The two inner walls of the mounting slot 8 have mating holes 9. The right side of the adjusting bracket 6 is externally mounted with a drive motor 11. The output shaft of the drive motor 11 has a protrusion on its surface and a screw hole inside. The size of the output shaft of the drive motor 11 is smaller than the inner diameter of the mating hole 9.

[0024] A locking pin 12 is inserted between two mating holes 9. The front end of the locking pin 12 has a threaded post. A cutting wheel 13 is provided inside the mounting slot 8. The center of the cutting wheel 13 has a hole with a shape corresponding to the output shaft of the drive motor 11. After the cutting wheel 13 is inserted into the mounting slot 8, the output shaft of the drive motor 11 is inserted through the mating hole 9 into the through hole inside the cutting wheel 13, so that the rotation of the cutting wheel 13 is synchronized with the output shaft of the drive motor 11. Then, the locking pin 12 is inserted into the mating hole 9 and connected to the output shaft of the drive motor 11 for locking installation.

[0025] The working principle of this utility model:

[0026] By using an adjustable bracket 6 with adjustable height, after connecting one end of the adjustable bracket 6 with a slot to the front surface of the mounting base 1, insert the two positioning shafts 15 into the corresponding positioning slots 14 respectively. The lower end of the positioning shaft 15 passes through the socket holes 10 on both sides of the adjustable bracket 6 and is then inserted into the lower positioning slot 14 for locking. After the adjustable bracket 6 is installed, it can slide up and down on the front side of the mounting base 1. After inserting the rotating handle 5 into the adjusting socket 4, rotating the handle at the top of the rotating handle 5 will cause the lower end of the rotating handle 5 to descend and insert into the docking slot 7, pushing the adjustable bracket 6 down. When cutting pipes, after the pipe is placed between the two supporting rollers 3, rotating the rotating handle 5 will push the entire adjustable bracket 6 down, so that the docking slot 7 abuts against the surface of the pipe. It has a good adjustment effect when clamping and cutting pipes with different outer diameters.

[0027] By using a drive motor 11 to drive the cutting wheel 13, the cutting wheel 13 is inserted into the mounting slot 8, and then the drive motor 11 is fixed on the right side wall of the adjusting bracket 6. The output shaft of the drive motor 11 passes through the docking hole 9 and is inserted into the through hole inside the cutting wheel 13. Since the output shaft of the drive motor 11 has protrusions, the rotation of the entire cutting wheel 13 is synchronized with the output shaft of the drive motor 11. Then, the locking pin 12 is inserted through the docking hole 9 into the threaded groove inside the output shaft of the drive motor 11 to lock it in place. The installation is completed by rotating the handle 5 to push the adjusting bracket 6 to fit against the surface of the pipe. The cutting wheel 13 cuts the surface of the pipe under the traction of the drive motor 11, which greatly improves the cutting efficiency of the pipe.
