Abstract

The invention relates to a surveying and mapping tool, especially a multifunctional surveying and mapping board, which includes a first surveying and mapping board and a second surveying and mapping board; A hub is installed below the position of the zero scale line of the scale line, and a wire rope is installed on the hub, and a winding shaft is fixed at the initial position of the scale line of the ruler; the first surveying board is also provided with a rectangular window at the lower position. , the upper and lower edge positions of the rectangular window are all provided with a chute in parallel, a straight board is installed between the two chute, and at least two straight holes for drawing lines are arranged on the straight board; the second surveying board is an angle ruler. The invention integrates the functions of drawing straight lines and parallel lines, measuring the length of large irregular objects outdoors, and measuring angles, has a simple structure, and is very convenient to use and carry. It is especially suitable for engineers who often work outdoors or in the field.

Description

technical field [0001] The invention relates to a surveying and mapping tool, in particular to a multifunctional surveying and mapping board. Background technique [0002] In the prior art, drawing a straight line and measuring length generally can use a ruler plate. But if can't draw parallel line by straightedge board alone, also inconvenient, perhaps can't measure the longer object than ruler board itself. Sometimes, the actual length of some large irregular objects outdoors is difficult to measure even with a steel tape. Therefore, engineers who often work outdoors or in the field often need to carry a variety of surveying and mapping tools for use together, which is very troublesome. Obviously, ordinary surveying boards have a single function, and cannot simultaneously draw straight lines and parallel lines, measure the length of large irregular objects outside, and measure angles, and these function sets are exactly the daily needs of engineers.
