[0023] Workbench 1 both ends are fixedly installed with support frame 4, support frame 4 is fixedly installed with drive motor 7, and support frame 4 is provided with a limiting mechanism for driving limiting clamp 21 to fix pipe 6 through drive motor 7, the limiting mechanism includes traction turntable 12 fixedly installed on the output end of drive motor 7, limiting long hole 16 is formed in support frame 4, and lifting slide block 15 is slidably sleeved in limiting long hole 16 and is movably pulled by traction turntable 12, first connecting rod 14 movement will pull lifting slide block 15 to reciprocate in limiting long hole 16 along the vertical direction, support frame 4 is pivotally installed with opening and closing swing lever 17 movably pulled by lifting slide block 15 and used for movably pulling fixed block 3, second connecting rod 18 is pivotally connected between lifting slide block 15 and opening and closing swing lever 17, traction long hole 19 is formed in opening and closing swing lever 17, and driven short yoke 20 is integrally connected on fixed block 3 and slidably sleeved in traction long hole 19, lifting slide block 15 moves up and down to pull opening and closing swing lever 17 to swing towards each other or in the opposite direction, and pull fixed block 3 to move horizontally towards each other or in the opposite direction, so as to clamp or release the pipe 6 to be machined.

[0024] To further explain, a long guide hole 2 for slidingly fitting the fixed block 3 is provided in the workbench 1, so that the fixed block 3 can move back and forth in a straight line along the long guide hole 2, and a feeding hole 5 for horizontally fitting the pipe 6 is provided in the support frame 4. The pipe 6 to be cut and processed is transported from the feeding hole 5 to the workbench 1, and the driving motor 7 pulls the limiting mechanism to operate, and the limiting clamp 21 moves slowly until the pipe 6 is clamped and fixed.

[0025] like Figure 3 、 Figure 4 As shown, an eccentrically arranged traction long bolt 13 is integrally connected to the traction turntable 12, and a first connecting rod 14 is pin-connected between the traction long bolt 13 and the lifting slider 15. When the traction turntable 12 rotates, the traction long bolt 13 performs a circular motion, which pulls the first connecting rod 14 to move, thereby converting the circular motion of the traction turntable 12 into a linear reciprocating motion of the fixed block 3.

[0026] The workbench 1 is movably mounted with a load-bearing support 8, to which a hydraulic telescopic rod 9 is fixedly mounted. A cutter 10 for cutting the pipe 6 is fixedly mounted at the output end of the hydraulic telescopic rod 9.
