Directional measuring device of tube push bench

A directional measuring device of a tube push bench is structurally characterized in that a circular hole A is formed in the central axis position below a fixing frame, a prism support is placed in the fixing frame, and a mounting hole below the prism support is aligned with the circular hole A and fixedly connected with the circular hole A through a forced centering screw; the prism is fixedly connected with the fixing bolt on the prism bracket; the stop board is installed in the fixing frame in an embedded mode. Three sets of telescopic adjusting devices are adopted, two sets of telescopic adjusting devices are fixedly welded to the fixing frame in a bilateral symmetry mode, and the other set of telescopic adjusting devices are fixedly welded to the central axis position over the fixing frame. The device is simple in structure and easy to operate on site, the point position is stable after the device is installed at the central point position of the tail of the tube push bench, a person does not need to ere
