As preferably, be provided with level meter A along axis direction on described parent tube.The tester can regulate the levelness of stadimeter according to this level meter A in measuring the lateral dimension process, avoid measuring stadimeter inclination in the lateral dimension process, the distance accuracy of improving the standard.
As preferably, described parent tube and draw-tube are cylindrical tube.Cylindrical tube has smooth curved surface, does not hinder hand, holds and feels comfortable, is fit to long-time the use.
As preferably, the described parent tube face of cylinder is provided with the rectangular parallelepiped pedestal, and described pedestal side is provided with level meter B perpendicular to axis direction.The rectangular parallelepiped pedestal is conducive to laying of stadimeter, can also provide a surface level that the level meter B of vertical parent tube axis is installed.The tester can regulate the verticality of stadimeter according to level meter B in the process of measuring vertical dimension, avoid stadimeter inclination in measuring process, improves vertical distance accuracy.
As preferably, described final section draw-tube head end is hemispherical head.Hemispherical head is the rounding off curved surface, as an end that contacts with measured object, can avoid scratching measured object, and when tested surface was curved surface, hemispherical head is contact surface preferably also.
As preferably, described draw-tube length is all less than parent tube length.Can guarantee that like this maximum occupying space at the stadimeter in when storage is parent tube and takes up space, inside protecting simultaneously, draw-tube can be not damaged in the process of transporting.
Therefore, the utlity model has following beneficial effect: (1) energy free-extension, measure flexibly all lengths; (2) have rigidity preferably, guarantee line measurement.
