[0027] The working principle of this utility model:

[0028] Refer to the instruction manual Figure 1-Figure 5 The utility model is provided with an inner support tube 3, a cavity 4, a push rod 5, a support rod 6, a rotating shaft 7, a torsion spring, and a first cylinder 8.

The length of the plastic composite tube sleeved on the outside of the inner support tube 3 can be determined according to the length of the plastic composite tube that needs to be cut. After the position of the plastic composite tube is adjusted appropriately, the first cylinder 8 is adjusted to extend and retract. When the first cylinder 8 is extended, the first cylinder 8 drives the push rod 5 to push forward, and the push rod 5 pushes the end of the support rod 6 located inside the cavity 4 forward, and the end of the support rod 6 located inside the cavity 4 swings forward, and the support rod 6 swings along the rotating shaft 7, and the end of the support rod 6 located outside the inner support tube 3 swings backward; the end of the support rod 6 located inside the cavity 4 gradually moves from an inclined state to a vertical state, and the support rod 6 is located inside the inner support tube 3. One end of the outer side of the tube 3 is gradually pushed and swung from the inclined state to the vertical state, and multiple support rods 6 cooperate to adjust the support radius of the inner support tube 3, so as to ensure the support of the inner wall of the plastic composite tube with different diameters. After the inner wall of the plastic composite tube is tightened, the cutting frame 2 is started to cut the plastic composite tube. Since the inner wall of the plastic composite tube is in a tightened state during cutting, the plastic composite tube can be effectively prevented from being deformed by pressure during cutting. After the cutting of the plastic composite tube is completed, the first cylinder 8 is adjusted to shrink, and the first cylinder 8 drives the push rod 5 to retract. The tightening force of the push rod 5 on the end of the support rod 6 is gradually reduced until it disappears, and the torsion spring rebounds and drives the support rod 6 to rebound and reset. The end of the support rod 6 located on the outer side of the inner support tube 3 is separated from the inner wall of the plastic composite tube, and then the plastic composite tube can be removed.

[0029] The auxiliary frame 16 supports the support shaft 17, and the support sleeve 18 rotates and sleeves on the outside of the support shaft 17. The second cylinder 20 is adjusted to perform telescopic adjustment. The second cylinder 20 drives the connecting piece 19 to swing, and the connecting piece 19 drives the support sleeve 18 to rotate a certain angle. The support sleeve 18 drives the inner support tube 3 to swing and adjust. When the inner support tube 3 is adjusted to be in a horizontal state, the plastic composite tube is sleeved on the outside of the inner support tube 3. After the cutting process of the plastic composite tube is completed, the inner support tube 3 is adjusted to swing, and the inner support tube 3 swings downward and moves downward through the opening 21. The plastic composite tube swings downward through the opening 21. The inner support tube 3 and the plastic composite tube are in a downward tilted state, and the plastic composite tube continues to fall downward into the receiving plate 22 for receiving work, so as to facilitate the collection and processing of the plastic composite tube after the cutting process.
