The utility model discloses a pendular sweeping motion mechanism for converting linear motion into multiple outputs, and relates to the technical field of mechanical transmission devices. The pendular sweeping motion mechanism comprises a driving mechanism capable of doing reciprocating linear motion, wherein the driving mechanism is correspondingly connected with a plurality of rocker arms through a plurality of sliding pins; all the rocker arms are fixedly connected with output devices respectively through output shafts at fixed positions; the driving mechanism drives the sliding pins to do reciprocating linear motion; the sliding pins drive all the rocker arms to do reciprocating pendular sweeping motion; all the rocker arms drive all the output devices to synchronously do reciprocating pendular sweeping motion through the output shafts. The pendular sweeping motion mechanism is simple in structure, small in abrasion point number, small in lubricating point number and high in reliability and is used for converting the linear motion into multiple outputs.
