When it is necessary to rotate the retraction member 44 and the clamping member 45, the second driving motor 421 starts and drives the drive spur gear 422 to rotate. The rotation of the drive spur gear 422 meshes with and drives the gear ring 433 to rotate. The rotation of the gear ring 433 can drive the support disc 432 to rotate, thereby driving the support disc 432, which plays the role of supporting the retraction member 44, to rotate.

[0038] Because the small piece of pipe after cutting is still in contact with the original pipe, so directly clockwise rotation of the small piece of pipe cutting will exist resistance or movement interference, thus the retreat piece 44 is made as follows: the retreat piece 44 includes a rectangular platform 441 fixed on the third support frame 434, two slide rails 447 are symmetrically installed in the rectangular platform 441, an active block 442 is slidably arranged on the two slide rails 447, and the clamping piece 45 is installed on the active block 442; the bottom of the rectangular platform 441 is provided with a third driving motor 443, the output end of the third driving motor 443 is connected with a third rotating shaft 444 penetrating through the thickness of the rectangular platform 441, the upper end of the third rotating shaft 444 is fixedly sleeved with a rotating disc 445, the rotating disc 445 is rotatably connected with a diagonal pull rod 446, and the end of the diagonal pull rod 446 away from the rotating disc 445 is rotatably connected with the end of the active block 442; in this way, the third driving motor 443 is started to drive the third rotating shaft 444 and the rotating disc 445 to rotate, so as to drive the diagonal pull rod 446 to pull the active block 442, realize the retreat of the active block 442 in the rectangular platform 441, and create conditions for the rotation and storage of the small piece of pipe obtained by cutting; conversely, after the clamping piece 45 is again put into the resistance and limitation of the end of the original pipe, the active block 442 only needs to be pushed to the initial position.

[0039] In the embodiment, the small piece of pipe obtained by cutting is carried by the clamping piece 45, retreats to the side away from the support assembly 2, and then rotates clockwise by 90 degrees; after reaching the position, the clamping piece 45 releases the small piece of pipe, so that the small piece of pipe falls into the storage groove 571 on the transmission rubber belt 57 by inertia; the transmission rubber belt 57 gradually delivers, which can realize effective storage of the small piece of pipe obtained by cutting, avoid accidental damage of the small piece of pipe obtained by cutting, and ensure the yield of the subsequent finished product.

[0040] In further embodiments, with reference to Figures 5-7As shown, the clamping piece 45 comprises two mounting frames 451 symmetrically mounted on the movable block 442, vertical plates 452 fixedly mounted on the two mounting frames 451, two vertical moving pieces 457 symmetrically mounted in the vertical plates 452, two support rods 456 connected to the two vertical moving pieces 457, and adhesive tapes 4561 connected to the opposite sides of the two support rods 456 by adhesives, so that the stability of the support limit is improved when the two support rods 456 abut against the inner edge of the pipe, and the two support rods 456 and the end faces of the two embedding blocks 4574 together form a good support limit effect on the end of the pipe; the vertical moving piece 457 comprises a roller bearing 4571 mounted on the inner wall of the vertical plate 452, a screw rod 4572 rotatably mounted in the roller bearing 4571, a driven bevel gear 4576 fixedly sleeved at the end of the screw rod 4572 away from the roller bearing 4571, a vertical moving block 4573 sleeved and threadedly connected outside the screw rod 4572, an embedding block 4574 fixedly connected to the exposed end of the roller bearing 4571, and the end of the support rod 456 away from the vertical moving block 4573 is fixedly connected to the embedding block 4574; the clamping piece 45 further comprises a fourth driving motor 453 fixedly mounted on the side surface of the vertical plate 452, a fourth rotating shaft 454 penetrating through the vertical plate 452 and connected to the output end of the fourth driving motor 453, and a driving bevel gear 455 fixedly sleeved outside the fourth rotating shaft 454 and meshedly connected with the two driven bevel gears 4576, so that the fourth driving motor 453 is started to drive the fourth rotating shaft 454 to rotate, and then drive the driving bevel gear 455 to rotate, thereby synchronously driving the two driven bevel gears 4576 to rotate, so that the two screw rods 4572 synchronously rotate to drive the two vertical moving blocks 4573 to move closer to or away from each other in the vertical direction, so as to achieve the purpose of supporting and limiting the end of the pipe by the two support rods 456; two groups of limiting grooves 4521 are symmetrically formed in the inner side wall of the vertical plate 452, and limiting blocks 4575 are inserted and slidably connected in the two groups of limiting grooves 4521, and the two groups of limiting blocks 4575 are fixedly connected with the upper and lower vertical moving blocks 4573, so as to ensure that the two vertical moving blocks 4573 move closer to or away from each other in the vertical direction in the vertical plate 452.

[0041] In this embodiment, when cutting, the hand pushes the pipe away from the rotating assembly 4, and the cutting end of the pipe is abutted and fixed by the clamping piece 45. Specifically, the fourth driving motor 453 is started to drive the fourth rotating shaft 454 to rotate, and then drive the driving bevel gear 455 to rotate, thereby synchronously driving the two driven bevel gears 4576 to rotate, so that the two screw rods 4572 synchronously rotate to drive the two vertical moving blocks 4573 to move away from each other in the vertical direction, thereby achieving the purpose of supporting and limiting the end of the pipe by the two support rods 456. This can effectively prevent the cutting end of the pipe from being accidentally raised during the operation of the shearing assembly 3, thereby ensuring the smooth progress of the cutting operation and the neatness of the cross section.

After reaching the position, the clamping piece 45 releases the small pipe pieces, so that the small pipe pieces fall into the storage grooves 571 on the transmission belt 57. The transmission belt 57 gradually delivers the small pipe pieces to realize sequential storage of the small pipe pieces, and achieves the storage purpose. After the transmission belt 57 is filled with small pipe pieces, the transmission belt 57 is continuously rotated to achieve the purpose of discharging the small pipe pieces stored on the transmission belt 57, which facilitates the centralized removal of the small pipe pieces and facilitates the workers to collect the small pipe pieces every certain period of time.
