Laser level with adjustable level line heights

The utility model discloses a laser level withadjustable level line heights. On the basis of the prior art, a driving motor and a level line adjusting mechanism are added, anda level light source emitter is controlled by mechanical actions, so that the level light source emitter rotates along the level lines; the posture of the level light source emitter is adjusted, so that angles of laser light rays, namely, the level lines, which are perpendicular to a spindle and emitted by the level light source emitter, can be adjusted, and the level lines with different heights can be obtained. Therefore, the position or the angle of the whole level is not required to be changed to enable projection angles of the level lines to be changed, and the defects that heights of level lines are realized through liftablesupports or adjustment of angle directions of whole levels, and heights of the support, heights of the levels and positions during line projection determine that projection positions of the level lines cannot be
