    • An improved laser level has a housing and a first shaft connected to the housing. Two bearings are disposed on the first shaft. A gimbal body is disposed on the two bearings. A second shaft is connected to the gimbal body. A third bearing is disposed on the second shaft. A pendulum is disposed on the third bearing. A laser diode is disposed on the pendulum. The housing is moveable between first and second positions, where the pendulum is self-levelling and not self-levelling respectively. A protrusion in an opening obstructs the laser beam when the housing is in the second position, but does not obstruct the laser beam when the housing is in the first position.
    • 改进的激光水平仪具有壳体和连接到壳体的第一轴。 第一轴上设有两个轴承。 两个轴承上设置万向节本体。 第二根轴连接到万向节主体。 第三轴承设置在第二轴上。 摆锤设置在第三轴承上。 一个激光二极管设置在摆锤上。 外壳可在第一和第二位置之间移动,摆锤可以自动调平并且不会自动调平。 当壳体处于第二位置时,开口中的突起阻挡激光束,但是当壳体处于第一位置时不会阻挡激光束。
