The laser level has a pendulum body in its casing for driving the laser emitting element to oscillate to produce horizontal and/or vertical laser lines to assist in aligning or adjusting the relative height of the target object. According to different leveling modes, the laser level is divided into gravity pendulum leveling and electronic leveling modes. The gravity pendulum leveling laser level adopts a movable pendulum body, a laser tube is arranged on the pendulum body, the pendulum body is vertical under the action of gravity, and the laser tube is marked with vertical and horizontal lines.

Although the locking mechanism comprising the shifting block, the torsion spring column and the locking wheel is adopted in the technical scheme, when the laser level is impacted greatly, the locking mechanism can not limit the pendulum body completely, thereby affecting the accuracy of the machine and even causing damage to the pendulum body and the laser. Based on this, it is highly desirable to design an impact-resistant and shatter-resistant laser level.
