Referring to fig. 1-6, a survey tool for mapping is suitable for high precision measurement of modern building and infrastructure construction. The tool mainly solves the problems of complex operation, unstable measurement and inaccuracy of the traditional measuring tool. The specific structure is as follows: comprising a telescopic tube 1, the telescopic tube 1 is a main body structure of the tool and is used for adjusting the total height of the tool. One end of the telescopic tube 1 is slidably connected with a height measurement fixing tube 2 in an inserting manner, and the fixing tube 2 provides stable support for the telescopic tube 1. One end of the height measurement fixed pipe 2 is slidably connected with a height measurement movable column 3 in a plugging manner, so that the tool can accurately measure different heights. And the bottom side of the height measurement fixed pipe 2 is provided with a locking stud 4, and the locking stud 4 is connected with the height measurement fixed pipe 2 in a threaded fit manner, so that the stability of the tool in the use process is ensured. The side of the telescopic tube 1 is provided with a guide groove 11 in a penetrating way, which helps the tool to be positioned better. And angle adjusting groove 12 and locking groove 13 have been seted up to the one end of flexible pipe 1, and angle adjusting groove 12 and locking groove 13 set up relatively, and the convenience of customers adjusts the angle according to actual demand. One end fixedly connected with screens board 24 of the fixed pipe 2 of height measurement, the equal fixedly connected with reference column 241 in both sides of screens board 24 has ensured the accuracy of height measurement. The other end side of the clamping plate 24 is fixedly connected with a positioning seat 21, and a first scale mark 22 is formed on the side surface of the height measurement fixing tube 2, so that a user can conveniently read measurement data. The second graduation marks 32 are arranged on the side face of the height measuring movable column 3, so that the measuring accuracy is further improved.

Referring to fig. 3-5, a positioning groove 111 is formed at one end of the guiding groove 11 to ensure stability of the measuring tool during use. The inner diameter of the positioning groove 111 is the same as the diameter of the positioning post 241, so that the tool is more stable in use.
