Description

Technical Field

[0001] The utility model relates to the technical field of sweepers, in particular to a portable laser sweeper for floor laying. Background Art

[0002] The laser leveler is an instrument that uses laser scanning to determine whether a surface is balanced. It projects a visible laser beam and can locate the height of the level according to the laser beam. Another concept is that the fast rotating shaft drives the visible laser point to sweep out light at the same horizontal height, which is convenient for engineers to locate the horizontal height. During the floor laying process, it is often necessary to use a laser leveler to measure and adjust the ground flatness.

[0003] When using an existing laser leveler, it is installed on a tripod. After emitting laser, the staff uses a receiver in different places to receive the laser, and then reads the reading according to the scale of the tower ruler. The leveler itself and auxiliary tools such as the tripod are all separate structures. It takes a certain amount of time to install them when using them, and they also need to be disassembled and stored separately when carrying, so it is not very convenient to use.
