The socket wrench is sleeved on the support pipe, and the socket wrench is connected to the support pipe through a bearing. The limiting rod passes through the socket wrench. A plurality of the flat pressing blocks are slidably connected to the outer wall of the support pipe. A plurality of the adjusting bolts penetrate into the support pipe from the inside of the support pipe, and the plurality of adjusting bolts are screwed to the support pipe and hinged to the flat pressing blocks, and the adjusting bolts correspond to the flat pressing blocks one by one.

[0006] As a further description of the above technical scheme:

[0007] An annular groove is formed on the support pipe, and the bearing is fixedly connected in the annular groove.

[0008] As a further description of the above technical scheme:

[0009] A kidney-shaped groove is formed on the socket wrench, and the limiting rod passes through the kidney-shaped groove.

[0010] As a further description of the above technical scheme:

[0011] A plurality of sliding grooves are formed on the outer wall of the support pipe, and a plurality of the flat pressing blocks are slidably connected in the plurality of sliding grooves.

[0012] As a further description of the above technical scheme:

[0013] A grip is provided at the end of the socket wrench.

[0014] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0015] In the present utility model, by inserting the support pipe into the pipeline and turning the adjusting bolt to firmly press the flat pressing block against the inner wall of the support pipe, the limit fixing of the support pipe in the pipeline is completed. The limit rod is inserted into the flange hole of the threaded flange after passing through the socket wrench. Under the support of the bearing, the end of the socket wrench is levered using the lever principle, causing the threaded flange to rotate, and thus the threaded flange is tightened. The use operation is simple and convenient, greatly improving the assembly efficiency of the threaded flange and the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS
