[0026] It further includes:

[0027] A motor 4, the motor 4 is fixedly arranged at the lower part of the box body 1 through bolts. A support rod 5 is rotatably connected to the inner bottom wall of the box body 1 through a thrust ball bearing. The output shaft of the motor 4 is connected to the support rod 5, and a first adjusting handle 6 is rotatably inserted on the support rod 5 through a bearing;

[0028] A bidirectional lead screw 7, the bidirectional lead screw 7 is rotatably connected inside the support rod 5 through a bearing, and the upper end of the bidirectional lead screw 7 is connected to the first adjusting handle 6. Two adjusting blocks 8 are sleeved on the bidirectional lead screw 7 through threads, and several connecting rods 9 are equally angled and hinged on the adjusting blocks 8;

[0029] Contact plates 10, there are several contact plates 10, which are respectively equally angled and suspended outside the support rod 5. One end of the connecting rod 9 passes through a strip-shaped through groove opened on the side wall of the support rod 5 and is hinged to the contact plate 10. A positioning plate 11 is fixedly arranged on the side wall of the contact plate 10, and a limiting mechanism 12 is arranged on the contact plate 10;

[0030] A threaded rod 13, the threaded rod 13 is rotatably inserted through the rear side wall of the box body 1 through a bearing. A second adjusting handle 14 is fixedly arranged at the rear end of the threaded rod 13 through bolts. A threaded sleeve 15 is sleeved on the threaded rod 13 through threads.

Scale lines 20 are arranged on the guide rods 18, so that the staff can understand the distance between the tool rest 16 and the scraping blade 17 from the support rod 5 through the scale lines 20;

[0032] The limiting mechanism 12 includes:

[0033] A flip plate 12-1, wherein the flip plate 12-1 is movably arranged in a groove provided on the upper portion of the abutment plate 10, a rotating rod 12-2 is fixedly provided on the flip plate 12-1, and both ends of the rotating rod 12-2 are screwed to the abutment plate 10 through bearings, and torsion springs 12-3 are movably sleeved at both sides of the rotating rod 12-2 located on the flip plate 12-1, and both ends of the torsion spring 12-3 are respectively connected to the flip plate 12-1 and the abutment plate 10;

[0034] There are two limit rods 12-4, both of which are fixed by bolts on one side wall of the flip plate 12-1. A pressure plate 12-5 is suspended on one side of the flip plate 12-1. The limit rods 12-4 are movably inserted in the pressure plate 12-5. An anti-skid pad 21 is bonded and fixed on the side wall of the pressure plate 12-5.

[0035] When using the utility model, several sealing rings are stacked and sleeved on several contact plates 10, and then the No. 1 adjustment handle 6 is turned, and the No. 1 adjustment handle 6 drives the bidirectional lead screw 7 to rotate, so that the two adjustment blocks 8 move synchronously in opposite directions, and the cooperation of the connecting rod 9 is used to achieve synchronous equidistant adjustment between the several contact plates 10 and the support rod 5, so that the several contact plates 10 all contact with the inner ring wall of the sealing ring, and then the pressing plate 12-5 is pulled upward so that the pressing plate 12-5 is higher than the vertical rod 19, and the torsion spring 12-3 drives the flip plate 12-1 and the rotating plate 12-3 to rotate. The rod 12-2 rotates, and the flip plate 12-1 drives the pressure plate 12-5 to flip to the top sealing ring to achieve the limiting effect on the sealing ring, and then the No. 2 adjusting handle 14 is rotated, and the No. 2 adjusting handle 14 drives the threaded rod 13 to rotate, and under the guidance of the guide rod 18, the threaded sleeve 15 drives the tool holder 16 and the scraper blade 17 to move, so that the scraper blade 17 contacts the edge of the sealing ring, and then the box cover 2 is closed, and the motor 4 is started again. The motor 4 drives the support rod 5 to rotate, so that the scraper blade 17 can trim the burrs on the edge of the sealing ring.

[0036] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0037] 1. Through the cooperation of the No. 1 adjustment handle 6, the bidirectional lead screw 7, the adjustment block 8, the connecting rod 9, the contact plate 10, the positioning plate 11 and the limit mechanism 12, the sealing ring can be adapted and fixed according to the inner diameter specification;
