The working principle and the beneficial effects of the technical scheme are as follows: when the size grow of piping lane, the interval between two external molds 10 will grow, through installation link 50 between first support body 1 and second support body 2 to conveniently install on the top of two external molds 10, through adopting different links, just can satisfy the external mold installation of different intervals, demolish first bolt 51 and second bolt 52 after the construction, just can take off the link, be convenient for deposit. The pulleys on the supporting platform 53 can slide in the sliding grooves in a reciprocating mode, the guiding and supporting functions are achieved, the deformation caused by overlarge span between the first frame body 1 and the second frame body 2 is reduced, and the installation accuracy of the outer die is improved.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
