Description

Technical Field

[0001] The utility model relates to the field of level equipment, in particular to a portable fixed frame for a level. Background Art

[0002] Today's level is an instrument that establishes a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points according to the principle of leveling. The main components are a telescope, a tube level (or compensator), a vertical axis, a base, and a foot screw. When the level is in use, it needs to be fixed with a bracket to ensure the level of the level. The level bracket is an indispensable structure during the use of the level. Fixed portable brackets on the market are in use. The level is an instrument used for measurement work in a variety of situations and environments. The level needs to remain stable during the measurement process, and the traditional level bracket is just a simple tripod. It is not easy to store and carry after the measurement is completed, and the bracket height cannot be adjusted at will. Utility Model Content
