摘要: A chainsaw(100) has a chainsaw body(101), cutting chain(103) driven by motor, and guide bar mounting stud (111) extending from the body (101). The also an adjustably connected bar(102) having track for supporting chain (103) around periphery of (102) adjustment pin (114) side face thereof. is configured to extend through elongated slot(112) in bar(102). cam (116) received on stud(111) eccentric groove facing (102). such that rotation cam(116) causes move with respect thereby tensioning chain(103). clutch(118) allowing no more than predetermined load be applied
