A number of strip grooves 6 are equidistantly provided on the outer surface of the conveyor belt 5, and the pipe fittings are located in the strip grooves 6 during transportation.

[0025] like Figure 4 As shown, a fixed frame 11 is symmetrically arranged along the rectangular through groove 15 at the top of the operating table 3, and the fixed frame 11 is slidably connected to the operating table 3; a second slide groove 28 is provided at the top of the operating table 3, and a connecting seat 29 that passes through the second slide groove 28 is connected to the bottom of the fixed frame 11.
