Abstract

The invention discloses a surveying and mapping instrument for land resource management. The instrument comprises a telescope and a support frame. A first fixing plate is arranged at the bottom of thetelescope; a second fixing plate is arranged at the top of the support frame; a first supporting sleeve is arranged at the top of the second fixing plate; a third fixing plate matching the first fixing plate is arranged at the top of the first supporting sleeve; a second supporting sleeve is arranged at the bottom of the third fixing plate; the second supporting sleeve is movably arranged outsidethe first supporting sleeve in a sleeving manner; a first through hole is formed in the second fixing plate; a first connecting rod is arranged in the first through hole in a communicating manner; athird supporting sleeve is arranged at the bottom of the third fixing plate; the third supporting sleeve and the first connecting rod are connected together through mutual meshing of a first fixing disc and a first groove, the first connecting rod can rotate relative to the third supporting sleeve, the first connecting rod is screwed to adjust the height of the third fixing plate conveniently, sothat the height of the telescope can be conveniently adjusted.

Description

technical field [0001] The invention relates to the technical field of land resource management, in particular to a surveying and mapping instrument for land resource management. Background technique [0002] As we all know, in the field of land resources management, the level will be widely used. The level is an instrument that establishes a horizontal line of sight to measure the height difference between two points on the ground. It measures the height difference between ground points according to the principle of leveling. and a support frame, and an adjustment plate for adjusting the level is set at the bottom of the telescope. During the use of the level, after adjusting the level of the level, if you need to adjust the height of the telescope when using the level, you can only adjust it. It is very troublesome to adjust the height of the telescope by adjusting the inclination angle of the support frame, and then readjust the level of the telescope. In addition, the he...
