[0020] In this embodiment: the mounting frame 5 is driven to move forward once by starting the hydraulic push rod 3, and under the action of the transmission wheel 17, the first rack plate 15 and the second rack plate 16 move relative to each other. At this time, under the action of the roller 4 and the limit ring 7, the purpose of bending the insulation pipe is achieved.

[0021] Please refer to Figure 2 and Figure 4 , the top of the bottom plate 8 is rotatably connected with a fixed shaft 9, the outer side of the fixed shaft 9 is fixed with a limit ring 7, an arc ring 14 is fixed on one side of the main body 1, one end of the bottom plate 8 is rotatably connected with a gear 10, the bottom end of the arc ring 14 is provided with teeth, and the teeth are meshed with the gear 10, the gear 10 cooperates with the teeth, when the gear 10 and the arc ring 14 move relative to each other, the gear 10 rotates, and the end of the gear 10 is fixed with a rotating shaft 11 that penetrates into the bottom plate 8, and a worm 13 is provided on the outer side of the rotating shaft 11, the gear 10 drives the worm 13 to rotate through the rotating shaft 11, the bottom of the fixed shaft 9 is fixed with a turbine 12 that meshes with the worm 13, the worm 13 drives the turbine 12 to rotate, and the turbine 12 drives the limit ring 7 to rotate;

[0022] Please refer to Figure 1 One side of the main body 1 is provided with an arc groove that cooperates with the bottom plate 8. When the bottom plate 8 continues to move forward, it gradually enters the arc groove. At this time, the bottom plate 8 rotates. When the bottom plate 8 is turned over, the gear 10 enters the arc ring 14.

[0023] In this embodiment: when the bottom plate 8 is located at the rightmost side of the main body 1, the bottom plate 8 flips over, and the gear 10 enters the arc ring 14 at this time, the bottom plate 8 continues to flip over, the gear 10 cooperates with the teeth, and the gear 10 rotates.
