Inside the support rod, the limiting rod is movably sleeved on the top of the positioning rod. The spring is fixed between the limiting rod and the bottom of the support rod. The limiting rod fits into the limiting hole. In use, pressing the limiting rod causes it to compress the spring and move to the inside of the support rod. Then, the support rod is inserted into the first rectangular ring, and the other side is inserted into the first rectangular ring at the top of the adjacent pipe until the limiting rod is aligned with the limiting hole. At this point, the limiting rod returns to its original position under the action of the spring and is inserted into the limiting hole, thus fixing the support rod in the position between the first rectangular rings. This fixes adjacent pipes without the need for bolts, facilitating the rapid splicing and installation of pipes.
[0006] Preferably, the splicing mechanism includes a second rectangular ring and a fixing rod. The second rectangular ring is fixed to the outside of the pipe, and the fixing rod is fixed to the outside of the pipe.

When the pipes are spliced together, the fixing rods are inserted into the inside of the second rectangular ring, which facilitates the initial fixing between the pipes. At this time, the first rectangular ring is in an aligned state, which facilitates the subsequent insertion of the support rods.
[0007] Preferably, the second fixing mechanism includes a protruding block, a U-shaped block, a vertical rod, a sleeve rod, and a fixing screw. The protruding block is fixed to the top of the pipe, the U-shaped block is sleeved on the top of the protruding block, and the protruding block and the U-shaped block are fixed together by bolts. The vertical rod is fixed at the center of the top of the U-shaped block, the sleeve rod is movably sleeved on the top of the vertical rod, and the fixing screw is threaded through one side of the sleeve rod. A rotating block is fixed on one side of the fixing screw to facilitate rotation of the fixing screw. A mounting plate is fixed at the top of the sleeve rod, and the mounting plate has mounting holes. In use, the pipe can be fixed by bolts through the mounting holes on the mounting plate. During installation, the sleeve rod moves along the vertical rod to adjust the installation height, and the fixing screw presses and fixes the pipe, facilitating installation at different heights and improving the applicability of the device.
[0008] Preferably, four first rectangular rings are provided, which are respectively installed at the four corners of the top of the pipe.
[0009] Preferably, the limiting rod extends movably to the outside of the support rod.
[0010] Preferably, there are two second rectangular rings, which are symmetrically installed on both sides of the pipe.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. When using this utility model, pressing the limiting rod causes it to compress the spring and move to the inside of the support rod. Then, the support rod is inserted into the first rectangular ring, and the other side is inserted into the first rectangular ring at the top of the adjacent pipe until the limiting rod is aligned with the limiting hole. At this time, the limiting rod is reset and inserted into the limiting hole under the action of the spring, so that the support rod is fixed in the position between the first rectangular rings. This fixes the adjacent pipes without the need for bolts, which facilitates the quick splicing and installation of pipes.
[0013] 2. In use, this utility model can fix the pipe by using the mounting holes on the mounting plate with bolts. During installation, the sleeve moves along the vertical rod to adjust the installation height, and is then fixed by the fixing screw, which facilitates installation at different heights and improves the applicability of the device.

The spring 14 is welded and fixed between the limiting rod 13 and the bottom of the support rod 6. The limiting rod 13 fits into the limiting hole 3. When in use, pressing the limiting rod 13 causes it to squeeze the spring 14 and move to the inside of the support rod 6. Then, the support rod 6 is inserted into the first rectangular ring 2, and the other side is inserted into the first rectangular ring 2 at the top of the adjacent pipe 1 until the limiting rod 13 is aligned with the limiting hole 3. At this time, the limiting rod 13 is reset and inserted into the limiting hole 3 under the action of the spring 14, so that the support rod 6 is fixed in the position between the first rectangular rings 2. This fixes the adjacent pipe 1 without the need for bolts, which facilitates the quick splicing and installation of the pipe 1.
[0021] The splicing mechanism includes a second rectangular ring 4 and a fixing rod 5. The second rectangular ring 4 is welded and fixed to the outside of the pipe 1. There are two second rectangular rings 4, which are symmetrically installed on both sides of the pipe 1. The fixing rod 5 is welded and fixed to the outside of the pipe 1. There are two fixing rods 5, which are symmetrically installed on both sides of the pipe 1. The fixing rod 5 fits into the second rectangular ring 4. When the pipe 1 is spliced, the fixing rod 5 is inserted into the inside of the second rectangular ring 4, which facilitates the initial fixation between the pipes 1. At this time, the first rectangular ring 2 is in an aligned state, which facilitates the subsequent insertion of the support rod 6.
[0022] The second fixing mechanism includes a protruding block 7, a U-shaped block 8, a vertical rod 9, a sleeve rod 10, and a fixing screw 11.
