Constructional engineering detection mirror

The utility model discloses a constructional engineering detection mirror. Supporting rod, an auxiliary rod is arranged on one side of the supporting rod; the auxiliary rod and the supporting rod areconnected through a connecting plate. A telescopic rod is arranged at the front end of the supporting rod; the end part of the telescopic rod is in threaded connection with a first lens; an adjustingrod is arranged at one end, facing the first lens, of the auxiliary rod; the end part of the adjusting rod is in threaded connection with a second lens; the first lens and the second lens have the same structure but different sizes. According to the technical scheme of the utility model, an existing detection mirror is generally of a single-mirror structure. However, in the actual operation process, single-lens inspection cannot be aligned for effective detection; by improving and optimizing the structure of the detection mirror, the detection mirror can have a double-mirror inspection function, and the inclination ang
