Displacement laser measuring device for civil engineering

The invention is suitable for the technical field of measuring equipment, and provides a displacement laser measuring device for civil engineering. Comprises: a support member; the gradienter is mounted on the supporting component, the ball joint seat is mounted on the supporting component, a universal ball is rotatably arranged in the ball joint seat, a counterweight ball is fixedly mounted at the bottom of the universal ball, a mounting seat is fixedly mounted at the top of the universal ball, and a displacement laser measuring instrument is mounted on the gradienter; and a locking mechanism for locking the position of the universal ball is arranged in the ball joint seat. The horizontal position of the installation base is locked, then the displacement laser measuring instrument is installed on the installation base, it is guaranteed that the displacement laser measuring instrument conducts measurement in the horizontal state, and therefore the measurement accuracy is guaranteed. 本发明适用于测量设备技术领域，提供了一种土木工程用位
