The lower end of the second motor 16 is extended with a rotating shaft 17, and the lower end of the rotating shaft 17 is fixedly connected to a missing gear 18, and the missing gear 18 is meshed with the first gear 13; the second motor 16 can drive the missing gear 18 to rotate through the rotating shaft 17, thereby intermittently driving the first gear 13 to rotate, thereby driving the movable sleeve 14 to rotate, and driving the outer cover 7 to rotate intermittently through the protrusion 15, and stopping for a period of time when the limit groove 21 in the outer cover 7 is facing the left and right.

[0025] The track groove 19 includes a high-level track 22, two groups of inclined tracks 23 are arranged on one side of the high-level track 22, and a low-level track 24 is arranged on one side of the two groups of inclined tracks 23. The lower end of the workbench 1 is rotatably connected with two groups of driving rollers 3, and a first motor 2 is arranged on one side of one group of driving rollers 3. A conveyor belt 4 with sandpaper is sleeved between the two groups of driving rollers 3, and the upper half of the conveyor belt 4 with sandpaper is located above the workbench 1, and the outer surface of the conveyor belt 4 with sandpaper is sandpaper. When the movable sleeve 14 rotates around the fixed shaft 12, the ball 20 slides on the track groove 19. When the limit groove 21 is facing the left and right, the ball 20 is just located at the intersection of the low-level track 24 and the two groups of inclined tracks 23, respectively. When 21 rotates from the left to the right, the ball 20 passes through the inclined track 23, the high-level track 22, the other set of inclined tracks 23 and finally returns to the low-level track 24, and the movable sleeve 14 first descends and then remains motionless and then rises, and after the attendance machine housing moves into the limiting groove 21 with the sandpaper conveyor belt 4, during the rotation of the outer cover 7 from the left to the right, the lower pressure plate 9 first presses down the attendance machine housing and then remains motionless, and finally slowly releases the attendance machine housing upwards, because when the attendance machine housing is in the limiting groove 21, the sandpaper conveyor belt 4 moves relative to the attendance machine housing, the burrs on the lower surface of the attendance machine housing can be polished, and when the limiting groove 21 rotates to the right, it continues to move to the right with the sandpaper conveyor belt 4.

[0026] The upper end of the workbench 1 is fixedly connected to multiple groups of limit plates 8, and the limit plates 8 are adapted to the size of the limit grooves 21.

When the limit groove 21 faces the left and right directions, the ball 20 is located at the intersection of the low-level track 24 and the two sets of inclined tracks 23 respectively. When the limit groove 21 rotates from the left to the right, the ball 20 passes through the lower track 24 and the two sets of inclined tracks 23 in sequence. The inclined track 23, the high-level track 22, and another set of inclined tracks 23 finally return to the low-level track 24, and the movable sleeve 14 first descends, then remains motionless, and then rises again. After the attendance machine casing moves into the limiting groove 21 with the conveyor belt 4 with sandpaper, the outer cover 7 rotates from the left to the right, and the lower pressure plate 9 first presses down on the attendance machine casing and then remains motionless, and finally slowly releases the attendance machine casing upwards. When the attendance machine casing is in the limiting groove 21, the conveyor belt 4 with sandpaper moves relative to the attendance machine casing, so the burrs on the lower surface of the attendance machine casing can be polished. When the limiting groove 21 rotates to the right, the conveyor belt 4 with sandpaper continues to move right to complete the polishing of the burrs.
