[0025] It should be noted that, since the existing deburring tool often uses a driving device to drive a polishing rod to rotate at high speed and deburrs through the contact between the polishing rod and the pull wire, the end of the pull wire is often scattered, so that the deburring operation cannot be completely contacted with the polishing structure, thereby causing part of the burr to be removed, and the deburring operation needs to be performed again, which is time-consuming and laborious and seriously affects the work efficiency. In order to solve this problem, the deburring mechanism 4 and the linkage mechanism 5 are arranged in the present scheme. The limiting cylinder 42 in the deburring mechanism 4 is used to limit the pull wire, and when deburring, the polishing bead 44 is abutted with the pull wire under the limiting action of the conical inner wall of the supporting cylinder 3, and the driving gear 55 in the linkage mechanism 5 drives the driven gear 51 to rotate, thereby driving the supporting cylinder 3 to rotate as a whole, so that the polishing bead 44 rotates outside the pull wire, thereby enabling the burr of the pull wire to be uniformly removed.

Then, the servo motor 52 is started to drive the driving rod 53 to rotate, the driving rod 53 drives the transmission rod 54 to rotate, the transmission rod 54 drives the driving gear 55 to rotate, and the transmission rod 54 drives the driving gear 55 to rotate. The transmission rod 54 is in threaded linkage on the threaded rod 57 through the screw hole 56, thereby driving the supporting plate 2 and the supporting cylinder 3 to move as a whole, so that the polishing bead 44 can move outside the pull wire.
