[0024] A driving wheel 7 is arranged inside the first mounting frame 4, and second mounting frames 5 are arranged on both sides of the outer top surface of the guide box 1. Rotating rods 6 are movably arranged inside the two second mounting frames 5. The rotating rods 6 can rotate inside the second mounting frames 5.

[0025] like Figure 2 As shown, two fixed plates 101 are fixedly installed inside the guide box 1, and sliding rods 102 are fixedly installed on both sides of the two fixed plates 101. The outer surfaces of the four sliding rods 102 are movably connected to two movable plates 104 respectively, and the movable plates 104 can move along the sliding rods 102.

[0026] Springs 103 are fixedly installed on both sides of the two fixed plates 101 , and the four springs 103 are fixedly connected to the two movable plates 104 respectively. When the movable plates 104 move, the springs 103 can be compressed.

[0027] The top surfaces of the two movable plates 104 are fixedly mounted with connecting rods 105 , and the two connecting rods 105 are respectively fixedly connected to the two second mounting frames 5 , so that when the two movable plates 104 move, the two second mounting frames 5 can be driven to move.

[0028] A roller 106 is movably installed inside the guide box 1, and a traction rope 107 is provided on the outer surface of the roller 106. The traction rope 107 is wound around the outer surface of the roller 106, and the two ends of the traction rope 107 are respectively fixedly connected to the two movable plates 104. When the roller 106 rotates, the traction rope 107 can be wound, and as the traction rope 107 is continuously wound, the two movable plates 104 can be driven to approach each other, and when the two movable plates 104 approach each other, the spring 103 can be squeezed.

[0029] Following the above practical example, Figure 3 As shown, a movable plate 108 is movably installed on the outer bottom surface of the guide box 1, and the movable plate 108 can rotate. One side of the movable plate 108 is movably connected to a limiting bolt 110. A plurality of limiting holes 109 are provided on the outer bottom surface of the guide box 1. By inserting the limiting bolt 110 into one of the limiting holes 109, the movable plate 108 can be prevented from continuing to rotate.

[0030] It should be noted that the movable plate 108 is fixedly connected to the roller 106 , and when the staff rotates the movable plate 108 , the roller 106 can be driven to rotate.

[0034] The working principle of the utility model is as follows: the staff first rotates the movable plate 108 according to the length of the pipeline to drive the roller 106 to rotate. As the roller 106 rotates, the traction rope 107 can drive the two movable plates 104 to approach each other. As the movable plate 104 moves, the spring 103 can be squeezed, and the movement of the movable plate 104 can drive the second mounting frame 5 to move until the two second mounting frames 5 are in a suitable position. The limiting bolt 110 can be rotated and inserted into one of the limiting holes 109. Then, the pipeline can be placed in the groove of the support ring 603, and the hydraulic cylinder 3 can be started to push the first mounting frame 4 down, and the driving wheel 7 can bend the pipeline.
