Document Type and Number:
WIPO Patent Application WO/2018/040701
Kind Code:
A1
Abstract:
Provided is a laser level, comprising a leveling mechanism (1) and a laser module (2). The leveling mechanism (1) comprises a base (11) provided with a support rod (12), a reference body (13) holding the laser module (2), a movable joint (14) movably connecting the support rod (12) and the reference body (13), a first lifting mechanism (15) acting on a first position of the reference body (13), and a second lifting mechanism (16) acting on a second position of the reference body (13). The first and second positions and a position of the movable joint (14) can be connected to form a triangle. The leveling mechanism (1) of the laser level maintains, via the movable joint (14), a degree of freedom required by the reference body (13), and calibrates the reference body (13) from different directions by means of the first lifting mechanism (15) and the second lifting mechanism (16). The laser level features a simple and reliable structure, a long service life, and a small degree of error.
