Portable laser convergence gauge device

The invention discloses a portable laser convergence gauge device, comprising a laser distance measuring meter, a grab handle, a female connector, a male embedded seat, a nut, a movable cover nut and a movable gasket. The portable laser convergence gauge device is characterized in that a connecting rod of the female connector is inserted into a groove of the grab handle and penetrates through a screw of the grab handle, the nut is screwed, and the female connector and the grab handle are connected together; the female connector and the male embedded seat are in butt joint by a rapid insertion female connector and a rapid insertion male connector, the connecting rod at the grab handle sequentially penetrates through the movable gasket and the movable cover nut, and the laser distance measuring meter is in threaded connection with the grab handle by the connecting rod at the grab handle. The portable laser convergence gauge device has the advantages that the connection is convenient, the structure is simple, the manufacturing cost is low and the positioning is rapid, and can be widely used for measuring the tiny change of the distance between two points along any direction of the surrounding rock periphery of a tunnel, a roadway, a chamber and other engineering.
