[0033] Specifically, when correcting PVC pipes of different diameters, first, according to the diameter of the PVC pipe, the limit on the movable wheel 2 is released by the limit component 9, and then the movable wheel 2 is moved to the specified position along the length direction of the fixed axis 3, and then the movable wheel 2 is limited by the limit component 9. At this time, the diameter of the PVC pipe is smaller than the spacing between the movable wheel 2 and the fixed wheel 1. At the same time, the distance between the two side panels 10 is adjusted by the driving component 8, and then the PVC pipe is placed between the fixed wheel 1 and the movable wheel 2.

The overall operation is simple, and the distance can be adjusted according to PVC pipes of different diameters. It is suitable for correcting PVC pipes of different diameters, which improves the scope of application of the device, reduces the overall volume of the device, and is easy to carry. It solves the problem that the existing PVC pipe correction tool increases the overall volume of the device while setting multiple sleeves, causing inconvenience for users to carry.

[0034] like Figure 1 and Figure 3As shown, in this embodiment, a rotating disk 16 is rotatably connected to the fixed block 13, and the limiting assembly 9 includes a movable plate 94, which is movably arranged in the fixed block 13, and a movable groove 96 is provided in the fixed block 13 for the movable plate 94 to move.

A traction rope 93 is fixedly connected to the end of the movable plate 94 away from the movable rod 91, and a spring 95 is sleeved on the traction rope 93, and the spring 95 is located in the movable groove 96. The end of the traction rope 93 away from the movable plate 94 extends to the outside of the fixed block 13 and is fixedly connected to the rotating disk 16, and a groove 14 is provided on the rotating disk 16 for the traction rope 93 to move.

When the position of the movable wheel 2 needs to be adjusted, the traction rope 93 is pulled by the rotating disk 16, and the traction rope 93 pulls the movable plate 94, thereby driving the movable rod 91 to pull the clamping plate 92 away from the fixed shaft 3. At this time, the movement of the movable wheel 2 can be achieved. When moving to the specified position, by loosening the rotating disk 16, the movable plate 94 is reset under the elastic force of the spring 95, that is, the clamping plate 92 is fit with the fixed shaft 3 again, and with the assistance of the frosted particles 12, the clamping plate 92 is tightly connected to the fixed shaft 3.

[0037] Working principle:

[0038] When correcting PVC pipes of different diameters, firstly, the traction rope 93 is pulled by rotating the rotating disk 16 according to the diameter of the PVC pipe, and the traction rope 93 pulls the movable plate 94, thereby driving the movable rod 91 to pull the clamping plate 92 away from the fixed shaft 3, and the movement of the movable wheel 2 can be realized. When moving to a specified position, the rotating disk 16 is loosened, and the movable plate 94 is reset under the elastic force of the spring 95, that is, the clamping plate 92 is re-fitted with the fixed shaft 3, so as to limit the movable wheel 2, and at the same time, the worm wheel 83 is driven to rotate by rotating the worm 85, so that the worm wheel 83 drives the rotating shaft 84 to rotate, and the rotating shaft 84 drives the gear 8 1 rotates, the gear 81 drives the two racks 82 to move relatively, so as to realize the relative movement of the two side plates 10, and then the PVC pipe is placed between the fixed wheel 1 and the movable wheel 2, and then the support rod 4 is grasped and the handle 5 is rotated, so that the handle 5 drives the top plate 11 to contact with the PVC pipe and correct it. The overall operation is simple, and the distance can be adjusted according to the PVC pipes of different diameters. It is suitable for correcting PVC pipes of different diameters, which improves the application range of the device and solves the problem that the existing PVC pipe correction tool will increase the overall volume of the device while setting multiple sleeves, causing inconvenience for users to carry.
