The guide ring 500 is disposed coaxially with the sleeve scraper 300 on the base 100, and the guide ring 500 is disposed corresponding to the upward end of the sleeve scraper 300. The guide ring 500 is provided with a plurality of guide wheels 510, and the guide wheels 510 are arranged in a ring along the guide ring 500.

The air blowing mechanism is disposed on the base 100 and disposed toward the sleeve scraper 300. The air blowing mechanism is electrically connected to the driving assembly 400, so that the blowing mechanism can be controlled to start or stop by the dome switch 410.

Referring to FIG. 3, the foregoing welding head 10 includes an outer tube 11 and an inner tube 12. The inner tube 12 is disposed inside the outer tube 11, and the inner tube 12 passes the electrode 20, and the welding rod 20 passes through the inner tube 12. The outer tube 11 is projected for welding.

Referring to FIGS. 4-5 and 6-7, in the use of the burr trimming device of the present invention, the horn 10 is moved downwardly through the guide ring 500 toward the sleeve scraper 300 and mated with the sleeve scraper 300. The guide wheel 510 on the guide ring 500 is capable of guiding the horn 10 through the guide ring 500 and aligning the sleeve scraper 300, the sleeve scraper 300 penetrating into the outer tube 11 of the horn 10 and nesting the inner tube 12. When the horn 10 is moved down, the slider 420 of the drive assembly 400 is pushed. When the slider 420 is pushed down to the squeezing dome switch 410, the drive assembly 400 can activate the motor 200 and the air blowing mechanism. The motor 200 drives the sleeve scraper 300 to rotate such that the blade portion 310 of each of the scraper grooves 301 of the sleeve scraper 300 rotates to remove the slag on the surface of the inner tube 12 of the horn 10. The air blowing mechanism is used to blow off the slag that has been cut. After the welding head 10 is finished trimming, the upward returning, the return spring 430 lifts the slider 420 away from the dome switch 410, and the motor 200 and the air blowing mechanism are stopped.
