By setting the threaded wire 412, the two extrusion plates can be easily connected and fixed together, thereby facilitating extrusion and fixation.
[0026] See also Figures 1 to 4 As shown, the inner wall of each rotating ring 403 is rotatably connected to the outer surface of the connecting pipe 1, the outer surface of each rotating ring 403 is rotatably connected to the inner wall of the mounting ring 402, the inner wall of each mounting ring 402 is slidably connected with four limit blocks 404, the top of each thread 412 is threadedly connected with a nut 413, and the bottom surface of each nut 413 is in contact with the upper surface of the upper extrusion plate 408. By setting the nut 413, the distance between the two extrusion plates can be shortened by rotating the nut 413, so that the connecting pipe 1 and the sealing ring 414 can be squeezed.
[0027] See also Figure 1 、 Figure 2 and Figure 3 As shown, the outer surface of each limit block 404 is slidably connected to the inner wall of the rotating ring 403, and each limit block 404 is fixedly connected to a spring 405 on a side close to the mounting ring 402. The outer surface of each rotating ring 403 is fixedly connected to a handle 406, and the outer surface of each handle 406 is fixedly connected to an anti-slip pad 407. By providing the handle 406 and the anti-slip pad 407, it is convenient for the staff to drive the rotating ring 403 to rotate through the handle 406, thereby improving the efficiency of the rotation of the device.
[0028] See also Figures 1 to 4 As shown, one end of each spring 405 away from the limit block 404 is fixedly connected to the inner wall of the mounting ring 402, and two sealing rings 414 are fixedly connected to the inner wall of the connecting pipe 1.

[0029] The specific working principle and method of the present invention are as follows: first, the staff transports the device to a suitable use position, then inserts one end of the steel pipe 2 into the connecting pipe 1, and then inserts one end of the plastic pipe 3 into the other end of the connecting pipe 1, so that the two pipes can be connected. When the steel pipe 2 is inserted into the connecting pipe 1, the fixed ring 401 and the rotating ring 403 on the connecting pipe 1 can enter the interior of the mounting ring 402 on the surface of the steel pipe 2. Similarly, when the plastic pipe 3 is inserted into the connecting pipe 1, the other fixed ring 401 and the rotating ring 403 on the connecting pipe 1 can enter the interior of the mounting ring 402 on the surface of the plastic pipe 3. After the rotating ring 403 enters the interior of the mounting ring 402, it can contact the limit block 404, and then the staff rotates the rotating ring 401. When 03 rotates, pressure can be applied to the limit block 404, so that under the action of pressure, the limit block 404 can move toward the inside of the mounting ring 402 until the rotating ring 403 is rotated to a suitable angle. The limit block 404 will be quickly rebounded to the inside of the rotating ring 403 for limiting under the elastic force of the spring 405, thereby effectively avoiding the situation where it is easy to fall off when the pressure in the pipeline is too high, improving the stability and firmness of the device during use, and at the same time, under the action of the spring 405, it can improve the convenience of reinforcing the device. Finally, the staff rotates the nut 413 to make the upper extrusion plate 408 and the lower extrusion plate 409 shrink and extrude, so that the sealing ring 414 can be squeezed firmly, thereby improving the sealing performance of the device.
