Abstract:
A swaying mechanism, which comprises:a synchronization motor having a rotating shaft;a first elbow member coupled to the shaft of the synchronization motor;a linkage bar, coupled to the first elbow member, for providing a reciprocating force when the first elbow member is being rotated by the synchronization motor;a second elbow member coupled to the linkage bar, the second elbow member being swayed by the reciprocating force from the linkage bar; anda toothed section on which the second elbow member is swayably mounted, whereinthe second elbow member is formed with a coupling axis, a coupling hole, a pair of protruded portions, and a plurality of toothed portions formed on the sidewall of the coupling hole; and when the coupling hole of the second elbow member is axially coupled to the toothed section, the protruded portions cause a flexible coupling affect between the teeth of the toothed section and the toothed portions of the second elbow member, allowing the toothed section to skip over the toothed portion on the sidewall of the coupling hole of the second elbow member when the swaying motion is abruptly stopped, thus protecting the synchronization motor from being burned out when such a condition occurs.
