Perpendicularity detection device for engineering quality detection

The utility model belongs to the technical field of engineering quality detection, and particularly relates to an engineering quality detection perpendicularity detection device which comprises a detection device body. The side wall of the detection device body is fixedly connected with a plurality of sliding rails; the plurality of sliding rails are uniformly distributed on the side wall of the detection device body and have the same structure; during use, the sliding blocks are inserted into the inner side walls of the sliding rails, then the screw rod is held and rotated, whether the detection device body is placed at a horizontal position or not can be ensured by observing the bubble level, and in the process, the situation that the ground of a building under construction is usually uneven can be reduced; the detection device body is difficult to use on the uneven ground, so that the detection effect of the detection device body is influenced to a certain extent, at the moment, the use effect of the detec
