However, this type of support method has a relatively single function, is inconvenient for laying pipes, and is inconvenient to use;

[0003] The solution is to place one end of the pipe to be laid on the support frame and control the other end of the pipe so that the pipe can be laid easily. When the pipe needs to be placed, one end of the pipe slides down from the inclined plate to improve the laying efficiency. Multiple protective frames can also be used to provide moving space for the support wheels.

[0023] When the position of the protective frame 4 needs to be adjusted, the pull ring 16 can be pulled first, and the twisting block 9 can be twisted with the other hand. The twisting of the twisting block 9 will drive the threaded rod 8 to rotate. Through the threaded cooperation, the two sliders 6 drive the protective frame 4 to move to achieve position adjustment.

[0024] Reference Figure 2 The moving mechanism includes a slide groove 7 opened on the inner walls on the left and right sides of the base frame 1, a guide rod 11 is fixedly connected between the front and rear inner walls of the slide groove 7 on the left side, and a slider 6 is slidably connected to the guide rod 11, and a threaded rod 8 is rotatably connected between the front and rear inner walls of the slide groove 7 on the right side, a threaded layer is provided on the threaded rod 8, and the slider 6 is threadedly connected to the threaded layer part, and the two sliders 6 are both slidably connected to the upper and lower inner walls of the corresponding slide groove 7, and the opposite surfaces of the two sliders 6 are fixedly connected to the left and right ends of the protective frame 4, and the protective frame 4 is provided with an inclined plate 5, and one end of the threaded rod 8 extends to the front side of the protective frame 4 and is fixedly connected to a torsion block 9.

[0025] The twisting of the twisting block 9 drives the threaded rod 8 to rotate, and the two slide blocks 6 drive the protective frame 4 to move through the threaded fit, thereby achieving position adjustment.
