Forming device for precast concrete inspection well

The invention discloses a forming device for a precast concrete inspection well, and relates to the technical field of inspection well production, the forming device comprises a body, a driving mechanism is located in a hole forming mechanism, a hole diameter adjusting mechanism is located on one side of the driving mechanism, a transmission mechanism is located above the body, the body comprises an inner mold, an outer mold is arranged outside the inner mold, and the outer mold is located above the inner mold. And moving wheels are arranged below the outer mold, the moving wheels are arranged below the connecting frame, and the outer mold is divided into two parts. According to the forming device, when the inspection well is poured and formed, a connecting hole mold does not need to be additionally placed through the hole forming mechanism, and after the inspection well is poured and the outer mold is opened, the hole forming mechanism moves along with the outer mold and shrinks, so that the hole forming mec
