  • Patent number: 11958121
    Abstract: A reciprocating power tool may include a driving system driving a reciprocating mechanism. A selection mechanism provides for selection of a linear mode of operation or at least one orbital mode of operation. Motion of a reciprocating shaft of the reciprocating mechanism may be guided by a guide bracket fixed in the housing and an orbit bushing movably coupled in the housing. The guide bracket may include at least one guide slot having a contoured guide surface that guides the motion of the corresponding end portion of the reciprocating shaft. The contoured guide surface may guide the corresponding end portion of the reciprocating shaft in a corresponding direction relative to the longitudinal centerline of the at least one guide slot during an out stroke and a return stroke of the reciprocating stroke.
