[0028] The above-mentioned limiting assembly is connected to the bottom support plate 401. When the bent titanium tube 25 is stably clamped on the lining plate 4, the titanium tube 25 covers the bottom support plate 401 and the flip plate 402 at the same time, causing the flip plate 402 to flip upward, and the titanium tube 25 near one end of the cutting assembly 10 is bent; in order to control the flip plate 402 to flip upward, a hydraulic cylinder 7 is provided on the above-mentioned horizontal pulling plate 3, and the piston rod of the hydraulic cylinder 7 is in contact with the bottom surface of the flip plate 402. By extending the piston rod of the hydraulic cylinder 7, the flip plate 402 can be controlled to flip upward.

[0029] The limiting assembly includes a first limiting portion 8 and a second limiting portion 9, which are arranged along the length direction of the operating platform 1, and there is a certain gap between the first limiting portion 8 and the second limiting portion 9.

The two vertical plates 801 are telescopic structures. Specifically, the two vertical plates 801 can be telescopically extended and retracted. By extending and retracting the two vertical plates 801 at the same time, the distance between the upper pressure plate 802 and the bottom support plate 401 can be adjusted. When the upper pressure plate 802 is adjusted to a suitable height, the vertical plates 801 can be locked in a fixed position.

[0030] See Figure 2 and Figure 4 As shown, the two vertical plates 801 of the first limiting portion 8 are connected with a positioning assembly, and two through holes are provided on each vertical plate 801 of the first limiting portion 8.
