Description

Technical Field

[0001] The utility model relates to the technical field of laser levels, in particular to a pendulum structure of a laser level. Background Art

[0002] The laser level is a full-space three-dimensional laser line device that can provide automatic leveling. Its working principle is that when tilted at an angle within the working range, the mutually perpendicular laser lines on the internal compensator pendulum always remain perpendicular to each other under the action of gravity.

Passive methods primarily utilize gravity suspension or liquid buoyancy to adjust the movement (pendulum structure), while active methods utilize mechanical drive to achieve leveling. Regardless of the adjustment method, the pendulum structure determines the performance and accuracy of the entire laser level. However, existing pendulum structures suffer from complex wiring, inconvenient adjustment, and difficulty in quick installation. Utility Model Content
