Therefore, the deformation of the pipe fittings needs to be corrected.

[0003] In the prior art, when a bent pipe is found to be defective after inspection, it is generally corrected by manually knocking or bending the pipe, but the correction efficiency is low. Utility Model Content

[0022] like Figures 1 to 4 As shown, a mounting plate 8 is integrally fixedly installed in the middle of the base 1, a hydraulic rod 9 is fixedly installed on the top of the mounting plate 8, a mounting seat 10 is fixedly installed on the movable end of the hydraulic rod 9, a connecting rod 11 is symmetrically rotatably installed in the middle of the mounting seat 10 through an axle pin, and the end of the connecting rod 11 away from the mounting seat 10 is rotatably connected to one side of the arc-shaped slider 3 through an axle pin.

[0023] The mounting seat 10 is driven to move by the hydraulic rod 9, and the support seat 4 is driven to slide along the track of the arc-shaped slide groove 2 through the connection of the connecting rod 11, so that the angle between the two positioning blocks 6 can be changed, and the pipes installed between the two positioning blocks 6 can be bent and corrected.

[0024] like Figures 1 to 4 As shown, movable grooves 12 are symmetrically provided on both sides of the support seat 4, and the positioning block 6 is slidably installed inside the movable groove 12. A sliding hole 13 is provided in the middle of the positioning block 6. A positioning rod 14 is fixedly installed at a position corresponding to the sliding hole 13 inside the support seat 4, and the positioning rod 14 is slidably connected to the sliding hole 13. An extrusion spring 15 is sleeved on the outer side of the positioning rod 14, and one end of the extrusion spring 15 is fixedly connected to one side of the positioning block 6, and the other end of the extrusion spring 15 is fixedly connected to the inner wall of the support seat 4.

[0025] By pushing the positioning block 6 to slide inside the movable groove 12, the extrusion spring 15 is in a compressed state, and the pipe fitting will move between the positioning block 6 and the support seat 4. The extrusion spring 15 will squeeze the positioning block 6 to drive the pipe fitting to be fixed between the two support seats 4 and the positioning block 6.

[0026] like Figures 1 to 4 As shown, a rounded corner 16 is provided at a top corner of the positioning block 6 .

[0027] The pipe fitting can be pressed downward to drive the pipe fitting to squeeze the rounded corner 16 on the top of the positioning block 6 to move the position between the two positioning blocks 6, thereby facilitating the fixation of the pipe fitting.

[0028] like Figures 1 to 4 As shown, a mounting hole 17 is opened in the middle of the support seat 4, and a top block 18 is slidably installed inside the mounting hole 17. A lifting spring 19 is fixedly installed at the bottom of the top block 18, and one end of the lifting spring 19 away from the top block 18 is fixedly connected to the bottom of the mounting hole 17 corresponding to the support seat 4.

At this time, the squeezing spring 15 is in a compressed state, and the pipe fitting will move to the position between the positioning block 6 and the support seat 4. Between the support seats 4, the positioning block 6 is squeezed by the extrusion spring 15 to drive the pipe fitting to be fixed between the two support seats 4 and the positioning block 6. After determining the required bending angle of the pipe fitting, the mounting seat 10 is driven to move by the hydraulic rod 9, and the support seat 4 is driven to slide along the trajectory of the arc-shaped slide groove 2 through the connection of the connecting rod 11 to correct the bending angle of the pipe fitting, and then the two positioning blocks 6 are pushed to move to both sides. The lifting spring 19 pushes the top block 18 to drive the pipe fitting to slide out of the middle part of the support seat 4 for taking out the pipe fitting.
