Synchronous detection device for multi-construction point environment

The utility model provides a synchronous detection device for a multi-construction-point environment. The synchronous detection device for the multi-construction-point environment comprises a first supporting leg and a second supporting leg, the four storage grooves are all formed in the first supporting legs; and the four first sliding grooves are formed in the bottoms of the inner walls of the four storage grooves correspondingly, and the interiors of the four first sliding grooves are slidably connected with rotating connecting blocks correspondingly. According to the synchronous detection device for the multi-construction-point environment, the supporting plate is opened through rotation, and the sliding connecting block is pushed to move to one side of the inner wall of the second sliding groove under the acting force of the spring, so that the supporting rod is lifted to push the rotating connecting block to move to the top of the inner wall of the first sliding groove; therefore, the whole detection de
