During the hot melt connection process, to avoid pipe deformation, the pipes are generally lifted and placed into the trench for connection. At this time, the bottom of the pipe is closely attached to the bottom of the trench, making it difficult to perform hot melt connection at the bottom of the pipe. Currently, on construction sites, local excavation is often carried out at the bottom of the pipe joint position for hot melt connection.

[0003] However, this method not only has low construction efficiency but also causes incomplete hot melt connection at the bottom of the pipe, resulting in insecure connection, failure to pass the water tightness test, and low qualification rate. There is an urgent need for an auxiliary tool for improving the qualification rate of pipe hot melting to solve the above problems. Content of the Utility Model

Both the front and rear ends of the arc-shaped guide seat are fixed with second side plates. A second electric push rod is installed at the relative inner ends of the two second side plates. Arc-shaped top pieces are symmetrically installed at the movable ends of the two second electric push rods. A plurality of universal wheel beads are installed on the circumferential sides of the two arc-shaped top pieces.

[0006] Furthermore, sliding sleeves are fixed at the front and rear sides of the lower end of the arc-shaped guide seat. Two strip-shaped grooves are formed on the upper end of the support plate. Guide rail rods are horizontally fixed in the two strip-shaped grooves.

[0007] Furthermore, the two sliding sleeves are respectively slidably installed outside the two guide rail rods.

[0008] Further, the arc-shaped guiding seat is directly to the left of the arc-shaped fixing seat.
