[0006] Preferably, a non-slip rubber sheet is fixed on the vertical side wall on the bayonet in the middle of the nut holder, which makes it easy to insert the nut. Since the two side planes of the nut are in contact with the non-slip rubber sheet, the nut cannot rotate, and the knife seat is against both ends of the nut so that the nut cannot move left and right, thereby facilitating processing.
[0007] Preferably, a sleeve handle with a fixing screw hole is fixedly provided at the rear end of the tool holder, and the sleeve handle is sleeved on the end of the output shaft of the servo motor and fixed by a fixing screw connected to the fixing screw hole.

[0010] Preferably, a telescopic rod is telescopically installed on the sliding seat, a sheath is fixedly provided at the front end of the telescopic rod, and a spring is provided on the outer sleeve of the telescopic rod, and the spring pushes the sheath forward, so that the sheath is sleeved on the outside of the tool holder during non-cutting, which effectively improves the safety; when the sliding seat approaches the nut holder, the sheath is blocked by the end face of the nut holder, and the tool holder continues to extend into the nut port for cutting and deburring, so that the flying burr waste will be intercepted and collected by the sheath, further improving the waste collection and processing effect.
[0011] The advantages and positive effects of the utility model are:
[0012] The tool holder is pressed against the two ports of the nut by a sliding seat that moves synchronously in both directions to achieve scraping. The bayonet design of the nut holder is convenient for loading and unloading materials, and can simplify the clamping structure while meeting the clamping requirements for deburring, greatly facilitating operation and improving efficiency.
[0013] The split tool design of the tool holder and alloy blade greatly reduces the cost of use.
[0014] The tool holder is protected by a retractable sheath, which effectively improves safety and can effectively collect the removed burrs and waste to avoid splashing. BRIEF DESCRIPTION OF THE DRAWINGS
