Detailed Description

In order to better understand the purpose, structure and function of the present utility model, a simple column type inspection pit track fine adjustment device of the present utility model will be described in further detail with reference to the accompanying drawings.

As shown in FIG. 1-FIG. 3, a simple column type inspection pit track fine adjustment device is composed of a gauge ruler 1, a sliding seat 2, a mini prism 3, a hammer ball 4 and a scale strip sticker 5, wherein the gauge ruler 1 can adopt a common gauge ruler or a digital display gauge ruler commonly used in the market, and the digital display gauge ruler is preferable. The gauge ruler comprises a ruler body, wherein two ends of the ruler body are a gauge ruler fixed end 11 and a gauge ruler movable end 12 respectively, and a gauge ruler handle 13 is arranged on the upper side face of the ruler body.

The length of the ruler body of the side, close to the fixed end 11 of the ruler, of the ruler 1 is measured from the fixed end 11 of the ruler to the center of the ruler 1, the corresponding ruler strip paste 5 (the insulating sleeve is not pasted) is pasted on the front ruler surface of the ruler 1, and the ruler strip paste 5 is a reverse 1-meter long aluminum material pasting strip paste.
