Umgomo wokusebenza we-wrench yegiya elingasheleli usekelwe ikakhulukazi kumshini we-ratchet. Isikrufu se-ratchet sinomshini wangaphakathi wokulinganisa ohlanganisa amagiya amaningana kanye nesondo le-ratchet. Uma isibambo sicushiwe, amagiya azungeza igiya lokugwedla, okwenza kube nendlela eyodwa yokuzungeza amandla kusikrufu. Lo mklamo uvumela i-wrench ukuthi ijikeleze ohlangothini olulodwa kuphela, njengokuhamba kwewashi noma ngokuphambene newashi, ukuze iqinise noma ikhulule amabhawodi namantongomane.
I-wrench yegiya elingasheleli linezici ezilandelayo: okokuqala, idizayini yayo yegiya inembe futhi iqinile, inamandla okubamba aqinile, akulula ukushelela, futhi kulula ukuyisebenzisa. Okwesibili, isibambo se-wrench samukela umklamo we-rubberized futhi ifakwe iphethini yokulwa nokushelela, engagugi futhi iphikisana nokushelela, futhi ikhululekile ukubamba. Ngaphezu kwalokho, ama-wrenches egiya angasheleli ngokuvamile enziwa ngezinto ezinobunzima obuphezulu, njengensimbi ye-carbon ephezulu, ukuze kuqinisekiswe ukuqina kwazo kanye nokukhishwa kwetorque ephezulu. Lezi zici zenza izikrufu zegiya ezingasheleli zizinze futhi zisebenze kahle.

Ubude besibambo | 220mm | 275 mm |
Ubude bebhande | 420 mm | 480mm |
Susa ububanzi | 40-100 mm | 40-120 mm |
Imihlahlandlela enemininingwane noma izinyathelo zokusebenzisa kahle isikrufu segiya elingasheleli imi kanje:
Ngokulandela lezi zinyathelo ezingenhla, ungaqinisekisa ukusetshenziswa okufanele kwesikrufu segiya elingasheleli futhi uqinisekise ukuphepha nokusebenza kahle komsebenzi.
