[0002] A ruler is a very commonly used length measuring instrument. It is used to measure straightness and flatness using the light gap method. It can also be used together with a gauge block to check length dimensions. By reading the value on the ruler, the measurement test is completed. A steel ruler is used to measure the length dimensions of parts, and its measurement results are not very accurate. This is because the spacing between the lines of a steel ruler is 1mm, and the width of the lines themselves is 0.1 to 0.2mm, so the reading error is relatively large during measurement, and only millimeters can be read, that is, its minimum reading value is 1mm, and values ​​smaller than 1mm can only be estimated;

[0003] At present, measurement units are compared with standards and steel rulers, which are directly placed on a platform and observed and compared by the naked eye. However, the existing steel ruler calibration platform is mostly fixed by squeezing and fixing the two ends of the steel ruler, which easily causes the steel ruler to bend during measurement, thereby affecting the measurement result. At the same time, when observing and comparing with the naked eye, it is easy to cause eye fatigue. In view of the above problems, the inventor proposes a measurement calibration steel ruler calibration platform to solve the above problems. Utility Model Content

[0022] By adopting the above technical solution, the top plate 31 is provided to facilitate the rotation of the screw rod 32, thereby enabling the slider 34 connected to the screw thread to be raised and lowered.

[0023] A rotating shaft 14 is rotatably connected at the center between the inner walls of the base 1 , a turning handle 12 is rotatably connected at the front end of the base 1 near the center, and one end of the rotating shaft 14 penetrates the base 1 and is fixedly connected to the turning handle 12 .

[0024] By adopting the above technical solution, the handle 12 is rotated, so that the fixedly connected rotating shaft 14 is rotated.

[0025] A vertical shaft 15 is rotatably connected to the top of the base 1 near the center of one side, and the top of the vertical shaft 15 passes through the base 1 and is fixedly connected to the screw rod 32 .

[0028] By adopting the above technical solution, bevel gear 1 16 is arranged at the bottom end of the vertical shaft 15 to cooperate with bevel gear 2 17 so that the vertical shaft 15 can drive the screw rod 32 to rotate.
