Description

Technical Field

[0001] The utility model relates to the field of levels, in particular to a swinging movement for a laser level and a laser level. Background Art

[0002] Laser levels can generate multiple vertical and horizontal laser planes to determine the accuracy of the horizontal and plumb direction, and are widely used in construction, decoration, and other fields.

[0003] A laser level is a device that can provide automatic leveling of three-dimensional laser lines in the entire space. Its working principle is that when the instrument is tilted at a small angle within the working range of the level, the four mutually perpendicular laser lines on the compensator pendulum inside the instrument always remain horizontal, plumb and perpendicular to each other under the action of gravity and magnetic field damping force.

[0004] Existing laser levels generally use a cross center axis to achieve the movement of the pendulum body within a certain range of arbitrary swing, and finally reach a balanced state under the principle of gravity and electromagnetic induction. However, the pendulum shaft mechanism that uses a cross center axis to achieve the movement of the pendulum body within a certain range of arbitrary swing has a relatively complex design structure and is not easy to process and shape, while increasing material costs and making it more inconvenient to disassemble and assemble parts.
