[0019] Furthermore, the first adjusting grinding mechanism includes a first push rod 340, a first electric cylinder 330, and a plurality of first grinding blocks 320. The first push rod 340 is sleeved inside the first sleeve. The first electric cylinder 330 is located at the right end of the first support frame 110 and is connected to the first push rod 340. The left end of the first grinding block 320 is hinged to the left end of the first cone 300. The right end of the first grinding block 320 is hinged to a first connecting rod, which is hinged to the left end of the first push rod 340.

[0020] Furthermore, the first grinding block 320 is provided with a first grinding blade 321 at one end away from the axis of the first cone 300, and the left end of the first cone 300 is provided with a plurality of first clearance openings 310, with the first grinding blade 321 corresponding to the first clearance openings 310 one by one.

[0021] Furthermore, the first pushing mechanism includes a second support frame 120, a first clamping frame 200, a first screw 130, and a second motor. The second support frame 120 is located at the left end of the first frame 100. The two ends of the second support frame 120 are provided with first guide rods 121. The lower end of the first clamping frame 200 is provided with a first guide block 240. The first guide block 240 corresponds one-to-one with the first guide rod 121.

The first electric cylinder 330 pushes the first push rod 340 to move to the left, which pushes the first grinding block 320 to flip outward through the first connecting rod, so that the first grinding blade 321 extends out of the first cone 300 through the first clearance port 310. Then, the first motor 350 drives the first gear 351 to rotate. Through the cooperation of the first gear 351 and the second gear 360, the first cone 300 is driven to rotate, which in turn drives the first grinding blade 321 to rotate, thereby grinding the cable protection tube 140 and repairing burrs.
