[0031] The supporting mechanism 3 is arranged outside the fixing mechanism 2 and is used to support the inner diameter of the pipeline.

[0032] In order to conveniently install and fix multiple electrode bodies 1 and assemble and disassemble the fixing mechanism 2, as shown in FIG. Figure 2 and Figure 3As shown, the fixing mechanism 2 includes a plurality of fixing seats 201, the inner wall of the fixing seat 201 is provided with a mounting hole 202 for mounting the electrode body 1, a plug-in block 203 is fixedly mounted on one side of the fixing seat 201, and a connecting groove 204 is provided on the inner wall of the other side of the fixing seat 201, the plug-in block 203 is movably connected to the inner wall of the adjacent connecting groove 204, and the six fixing seats 201 are spliced ​​through the connection between the plug-in block 203 and the connecting groove 204, and the electrode body 1 can be installed and fixed through the two opposite mounting holes 202.

[0033] In order to conveniently support the inner wall of pipes with different diameters, such as Figure 2 and Figure 4 As shown, the support mechanism 3 includes a rotating shaft 301, an adjusting knob 302 is fixedly installed on the top of the rotating shaft 301, and fixed blocks 303 are fixedly sleeved on the outer sides of the top and bottom of the rotating shaft 301. Six traction plates 305 are provided on the outer walls of the opposite sides of the two fixed blocks 303. A support plate 306 is rotatably installed on the end of the traction plate 305 away from the fixed block 303. The support plate 306 is arranged on the outer side of the adjacent fixed seat 201. The rotation of the adjusting knob 302 causes the rotating shaft 301 to rotate, and then under the traction action of the fixed block 303 and the traction plate 305, the support plate 306 can be driven to expand outward or contract inward, thereby supporting the inner walls of pipes with different diameters.

[0034] In order to keep the support plate 306 stable during the movement, Figure 2-4 As shown, telescopic parts 205 are rotatably installed on both sides of the outer wall at one end of the top of the fixed seat 201, and the ends of the two telescopic parts 205 away from the fixed seat 201 are rotatably connected to the inner ends of the adjacent support plates 306 respectively. The telescopic parts 205 can pull and limit the movement of the support plates 306, so that the support plates 306 remain stable during the movement.

[0035] In order to facilitate the assembly and disassembly of the plurality of fixing seats 201, Figure 2 and Figure 3 As shown, the front vertical sections of the plug-in block 203 and the connecting groove 204 are both arranged as rectangular structures, the top cross-section of the fixing seat 201 is arranged as a fan-shaped structure, and the six fixing seats 201 form a circular ring structure. Through the connection between the plug-in block 203 and the adjacent connecting grooves 204, the six fixing seats 201 of the device can be conveniently spliced ​​into a circular ring structure.

[0036] In order to ensure that the traction plate 305 can stably drive the support plate 306 to move, Figure 2 and Figure 4As shown, six mounting seats 304 are fixedly installed on the outer walls of the opposite sides of the two fixed blocks 303, and the outer sides of the mounting seats 304 are rotatably connected to the adjacent traction plates 305.

At the same time, the telescopic member 205 can pull and limit the movement of the support plate 306, so that the support plate 306 remains stable during the movement, and then the support plate 306 can support the inner wall of the pipe of different sizes, so that the patching device can adapt to the patching work of pipes of different sizes, and it can be convenient for the staff to replace the components of the patching device. This embodiment specifically solves the problem in the prior art that the components of the pipe patching device cannot be easily replaced due to damage, and cannot adapt to the patching work of pipes of different sizes.
