As the No. 1 electric slider 12 drives the cutting wheel 14 close to the fixed greenhouse steel pipe frame, the cutting wheel 14 rotates rapidly. The plurality of greenhouse steel pipe skeletons are automatically cut. After the cutting of the plurality of greenhouse steel pipe skeletons is completed, the No. 1 electric slider 12 drives the cutting wheel 14 to slide and reset, and continues to push the remaining greenhouse steel pipe skeletons to the cutting wheel 14 for cutting, thereby playing a role in stable cutting of a large number of greenhouse steel pipe skeletons of different specifications; when the plurality of greenhouse steel pipe skeletons of different specifications are fixedly cut, the plurality of greenhouse steel pipe skeletons are respectively passed through the middle hollow parts of the two support frames 2, and are respectively placed on the V-shaped grooves of the No. 1 limit block 21. The V-shaped grooves of the No. 1 limit block 21 can adapt to the placement of greenhouse steel pipe skeletons of different specifications. Under the drive of the transmission component, multiple No. 1 limit blocks 21 cooperate with the clamping component to stably adapt to the clamping of multiple greenhouse steel pipe skeletons, which is convenient for stable cutting of greenhouse steel pipe skeletons of different specifications; when clamping greenhouse steel pipe skeletons of different specifications, the transmission component is used to drive the connecting plate 31 to slide down, and the connecting plate 31 can synchronously drive multiple sliding rods 3 to slide down the inner wall of the support frame 2, and multiple No. 1 matching blocks 32 are fitted on the outer walls of the multiple greenhouse steel pipe skeletons for pressure covering, and the groove of the No. 1 matching block 32 cooperates with the V-shaped groove of the No. 1 limit block 21, which is tightly fitted on the outer wall of the greenhouse steel pipe skeleton for clamping, and through the four The contact clamping of each point can adapt to the stable clamping of greenhouse steel pipe skeletons of different specifications, and play a role in stable cutting of greenhouse steel pipe skeletons of different specifications; when cutting the greenhouse steel pipe skeleton, the cutting part of the greenhouse steel pipe skeleton is most likely to shake, and the output end of the hydraulic cylinder 41 on the side plate 4 is retracted to drive the two connecting plates 31 connected by the U-shaped plate 42 to slide down synchronously, and the two connecting plates 31 respectively drive multiple No. 1 matching blocks 32 to press down and clamp multiple greenhouse steel pipe skeletons, and stably clamp the two sides of the cutting part of the greenhouse steel pipe skeleton, so as to reduce the shaking and cutting deviation of the cutting part of the greenhouse steel pipe skeleton during cutting; When the greenhouse steel pipe skeleton is cut into multiple sections, the small sections cut off are more likely to shake during the cutting process than the long sections, resulting in uneven cut surfaces of the small sections. The No. 2 slide rail 5 is fixed to the end of the cutting machine base 1 on one side close to the cutting position.

The two support blocks 71 cooperate with the rubber block 72 to support the inner wall of the greenhouse steel pipe skeleton. The rubber block 72 can adapt to the inner wall of the greenhouse steel pipe skeleton of different specifications. After releasing the clamping of the greenhouse steel pipe skeleton, the sliding plate 7 can be pulled back to its original position by the No. 1 spring, thereby reducing the rolling deviation when intercepting the greenhouse steel pipe skeleton; when the inner wall of the greenhouse steel pipe skeleton of the intercepted part is supported, the connecting plate 31 is used to drive multiple When the sliding rod 3 slides down, the disc 81 fixed on the sliding rod 3 squeezes the gas in the extrusion tube 8, and the gas in the extrusion tube 8 is sent to the soft tube 83 through the hard tube 82, and the gas is then sent to the hollow rod 53 by the soft tube 83, so as to push the two sliding plates 7 to slide to the outside of the hollow rod 53, and cooperate with the support block 71 to press against the inner wall of the greenhouse steel pipe skeleton, so as to play the role of supporting and preventing the inner wall of the greenhouse steel pipe skeleton from rolling. When the connecting plate 31 drives the multiple sliding rods 3 to reset, the gas inside the hollow rod 53 is extracted into the extrusion tube 8, so as to release the support for the inner wall of the greenhouse steel pipe skeleton. At the same time, the soft tube 83 is made of soft material, which can facilitate the displacement of the fixed block 52. When intercepting the greenhouse steel pipe skeleton, the air pump 91 is used to generate gas to enter the connecting frame 92, push the No. 2 matching block 94 at the bottom of the multiple short rods 93 downward, and the No. 2 spring is stretched and stressed. The groove of the No. 2 matching block 94 cooperates with the V-shaped groove of the No. 2 limit block 9 to clamp the outer wall of the intercepted part of the greenhouse steel pipe skeleton. As the No. 2 electric slider drives the overall displacement of the fixed block 52, it can pull multiple intercepted parts of the greenhouse steel pipe skeleton, so as to play the role of cutting the intercepted part of the greenhouse steel pipe skeleton; When cutting the greenhouse steel pipe skeleton, a collecting plate 95 is fixed on the outside of the fixing frame 13. In the process of the No. 1 electric slide block 12 driving the cutting wheel 14 to cut the greenhouse steel pipe skeleton, the waste chip groove 96 is located below the cutting point of the greenhouse steel pipe skeleton to receive the waste chips, thereby collecting the waste chips of the greenhouse steel pipe skeleton and reducing the impact of the waste chips falling on the No. 1 slide rail 11 on the sliding effect of the No. 1 electric slide block 12.
