[0029] Specifically, the fixing plate 2 serves to connect the supporting plate 4 and the first fixing column 8, the first fixing column 8 serves to control the pipe clamping wheel 3, and at the same time, the first fixing column 8 can be pulled out from the middle of the pipe clamping wheel 3 in the vertical direction, and the pipe clamping wheel 3 serves to control the pipe, the annular sliding buckle 19 on the supporting plate 4 serves to slide and connect with the annular sliding groove 18, thereby realizing the effect that the rotating plate 7 can rotate, the second fixing column 10 serves to serve as the pipe bending rolling wheel 13, the pipe bending rolling wheel 13 serves to control the pipe and bear the pressure from the pipe during the pipe bending process, the fixing block 5 and the handrail 6 serve to facilitate manual operation, the supporting column 15 serves to provide installation conditions for the supporting tube 26, the supporting tube 26 serves to control the limiting tube 25, and the limiting tube 25 serves to control the pipe and apply pressure to the pipe to deform it.

[0030] Reference Figure 4A motor output groove 17 is provided in the middle of the support plate 4, and a plurality of thread grooves 24 are provided on the outer side of the annular sliding buckle 19, and a bolt 23 is threadedly connected in the middle of the thread groove 24.

After the pipe is placed, the reduction motor 1 is started, and the operator controls the handrail 6. When the operator applies force in a certain direction through the handrail 6, the reduction motor 1 and the force provided by the operator through the handrail 6 are jointly applied to the unbent pipe through the limiting tube 25 to cause the pipe to bend. While the operator controls the handrail 6 to bend the pipe, the angle scale 20 on the support plate 4 and the pointer 21 on the rotating plate 7 can help the operator determine the bending angle of the pipe. When the pipe is bent to a predetermined angle, the rotating plate 7 is fixed by threading the bolt 23 with the threaded groove 24. Then, when the pipe no longer generates deformation force, the support plate 4 and the rotating plate 7 are removed as a whole, and then the bent pipe is taken out.
