Abstract
A rotation mechanism for mounting and rotatably supporting a laser emitter thereon includes a casing including a bottom wall and a side wall connected to the bottom wall, said casing defining therein a receiving space. A plurality of rotation rings are arranged as being layered with each other in the receiving space of the casing. The rotation rings include an uppermost rotation ring in the form of a manual coarse rotation ring that is directly connected to the laser emitter so as to support the laser emitter, for manually rotating the laser emitter to achieve a coarse angular positioning thereof, an automatic coarse rotation ring for rotating the laser emitter at a relatively high speed together with the rotation ring thereon, a manual fine rotation ring for slightly rotating the laser emitter manually together with the rotation ring thereon, and an automatic fine rotation ring for rotating the laser emitter at a relatively low speed, together with the rotation ring thereon. The automatic rotation rings are each provided with a driving means that is arranged on the rotation ring immediately below the relevant rotation ring.
