When in work: the scraping rod 8 rotates along with the rotation of the main shaft 22, so that the chips on the horizontal operating table 1 are scraped and fall into the processing box 82 through the chip outlet 81 when passing through the chip outlet 81, and the chips generated by slope cutting are convenient to process in time.

The working principle is as follows: when the device works, the rubber block 3 with proper thickness is selected according to the diameter of the elbow pipe fitting to be cut on the slope, the rubber block 27 is fastened through the locking screw, clear water is filled into the small hole in the rubber block 3, one end of the elbow pipe fitting is sleeved on the rubber block 3 by hand, so that the elbow pipe fitting is expanded preliminarily, the elbow pipe fitting is pressed to be contacted with the cutter 41, the motor 21 is started, the motor 21 drives the main shaft 22 to rotate, the main shaft 22 drives the expansion block 27 to rotate due to the limitation of the L rod 29 and the rectangular groove 291, the connecting block 23 and the positioning rod 24 cannot rotate due to the limitation of the vertical rod 231 on the fixed groove, in sum, the expansion block 27 is driven to rotate when the main shaft 22 rotates, the expansion block 27 drives the inclined arc groove 26 to be limited due to the rotary drum 25 on the positioning rod 24, so that a plurality of groups of expansion blocks 27 move outwards, so that the rubber block 3 on the expansion block 27 fixes the elbow pipe fitting, and the problem that the elbow pipe fitting is difficult to fix on the straight pipe fitting and is easy to be cut askew when the slope is cut is avoided, when the rubber block 3 moves outwards to fix the inner wall of the elbow pipe fitting, the rubber block is extruded, so that clear water is separated out from small holes in the rubber block 3, the adsorption force of the rubber block 3 on the elbow pipe fitting is increased, and a better fixing effect is achieved;

when the expansion block 27 moves outwards, the L rod 29 moves outwards along with the L rod, after the elbow pipe fitting is fixed by the rubber block 3 on the expansion block 27, one end of the L rod 29 extending into the rectangular groove 291 just extends out of the rectangular groove 291 and extends into the abutting groove of the connecting block 23, the main shaft 22 loses the limit of the L rod 29, so that the expansion block 27 does not move after the main shaft 22 continues to rotate, the ejector rod 6 fixedly connected with the bottom of the expansion block 27 moves outwards at the moment, after the elbow pipe fitting is fixed by the rubber block 3 on the expansion block 27, the ejector rod 6 just abuts against the T-shaped block 61, so that the T-shaped block 61 moves downwards and is clamped into the straight groove 65 on the circular ring 66, and therefore the main shaft 22 can drive the cutter 41 on the cutter disc 4 where the limit groove 63 is located to rotate when rotating, so as to perform slope cutting on the fixed elbow pipe fitting The elbow pipe generates lateral pressure, so that the through pipe fitting is difficult to fix;

when the cutter 41 performs slope cutting on the elbow pipe fitting, the annular electromagnet 53 is started at the moment, the annular electromagnet 53 generates magnetic force so as to attract the lower ferromagnetic block 52 and enable the ferromagnetic block 52 to drive the cutter 41 to have a tendency of moving upwards, and when the cutter 41 performs slope cutting on the elbow pipe fitting, the cutter 41 having the tendency of moving upwards is more convenient for slope cutting of a slope angle with a larger size;

when the cutter 41 cuts the elbow pipe piece in a slope manner, the elbow pipe piece is splashed to the periphery by the fragments generated by the slope cutting, the splashed fragments are blocked by the ring frame 7 and fall on the surface of the horizontal operating platform 1, so that the fragments generated by the slope cutting of the elbow pipe piece are prevented from splashing and falling on the ground, and the design of the ring frame 7 enables workers holding the elbow pipe piece to be difficult to mistakenly touch the cutter 41 to be dissected and torn by the clothes corner, sleeves and the like, and is safer, the scraping rod 8 rotates along with the rotation when the main shaft 22 rotates, so that the fragments on the horizontal operating platform 1 are scraped and pass through the chip outlet 81, and fall into the processing box 82 through the chip outlet 81, and the fragments generated by the slope cutting are conveniently and timely processed.
