Carbon fiber measuring rod with double-rod structure

The invention provides a carbon fiber measuring rod with a double-rod structure, and relates to the technical field of large-size comparison measurement. The number of the pipe combining clamps is eight, and the eight pipe combining clamps are fixedly connected with two measuring rods. The two measuring rods are slidably connected with the two guide rail mounting bases, the left guide rail mounting base is provided with the quantitative claw, the left guide rail mounting base is provided with the first momentum claw, the two measuring rods are M40J carbon fiber tubes, the rigidity of the measuring tool is greatly improved in material and structure, the quantitative claw and the momentum claw are made of 7075-T651 aviation aluminum alloy, and the measuring accuracy is greatly improved. The overall weight is light and the rigidity is strong; 2, the interior of the measuring rod is of a hollow structure, so that the self weight of the measuring rod can be reduced, and the carrying convenience is improved; thirdl
