When in work:

cutting preparation: the rotary handle 261 is held by hand to rotate until the electric cutter 28 is adjusted to a proper angle, then the embedded part 264 is inserted into the insertion hole and the corresponding hole to lock the angle, and the electric cutter 28 is started to pre-rotate;

positioning: the automobile tail pipe is placed on the positioning device 3, the middle part of the tail pipe is embedded into the fit groove, then the two arc-shaped frames 321 are closed, the upper end of the extrusion plate 323 is limited by forward pushing of the positioning frame 35, at the moment, the ejection block 324 descends under extrusion of the extrusion plate 323, the fit plate 327 is pushed forward through the L-shaped frame 325, the middle part of the tail pipe is limited forward and backward by forward pushing of the fit plate 327 and abutting against the front end of the fit groove, the positioning frame 35 is pushed forward until the locking mechanism 36 is locked with the bottom frame 33, and the conductive plate 38 extends forward;

beveling: the electric slide block 21 drives the sealing frame 22 to move backwards until the positioning head 23 carries out external wrapping limiting treatment on the pipe orifice, at the moment, the power supply pack 30 is in contact with the extended conducting plate 38, and the electric push rod 29 drives the electric cutting machine 28 in an inclined state to descend along the inclined direction after being electrified, so that the pipe orifice of the tail pipe is obliquely cut;

taking out waste materials: the cut tail tube is removed, the positioning head 23 is pulled forward to remove the cut waste material together with the positioning head 23, and the positioning head 23 is removed and reinstalled.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
