Abstract

The invention discloses a length measuring device with supporting rods, belongs to the technical field of length measurement, aims to provide a length measuring device with supporting rods, and solvesthe problem that an existing measuring tool cannot perform accurate length measurement in a narrow space. The length measuring device comprises a shell, a locking screw is arranged on the shell, anda locked supporting rod and a movable supporting rod are connected to the shell. The movable supporting rod comprises a first measuring handle and a first measuring head. The locked supporting rod comprises a second measuring handle and a second measuring head. The first measuring head can rotate along the axis of the first measuring handle, and the second measuring head can rotate along the axisof the second measuring handle. A spring winding drum is installed in the shell, a rope is arranged on the spring winding drum, a measuring wheel and a guide wheel are installed in the shell, the ropeis wound around the measuring wheel, penetrates into the locked supporting rod through the guide wheel and then is fixed to the first measuring head of the movable supporting rod, and a reading mechanism is further installed in the shell. The scheme is applicable to the length measuring device.

Description

technical field [0001] The invention belongs to the technical field of length measurement, and in particular relates to a length measurement device with a support rod. Background technique [0002] Existing commonly used length measuring tools are mainly calipers, steel rulers, tape measures, curve measuring instruments, etc. Under some complicated conditions such as corners, gaps, holes, narrow spaces, etc., these measuring tools cannot be accurately positioned for accurate measurement. There are many measurement requirements under complex conditions in machining, installation, construction, decoration, etc., so how to provide a measurement tool that can measure under complex conditions is an urgent problem in this field. Contents of the invention [0003] The object of the present invention is to provide a length measuring device with a support rod to solve the problem that existing measuring tools cannot perform accurate length measurement in a narrow space. [0004] T...
