Njengoba wonke umuntu azi, iningi lamantongomane ethayi lezimoto noma ngabe liyahlangana futhi lihlakazwa futhi lilungiswa, ngaphezu kobuchwepheshe obukhona be-pneumatic wrench wrench yi-spanner wrench kanye nokuvuleka kwesokhethi okuyimishini kuphela, enganele ekusetshenzisweni ayihambisani nenani lesondo lemoto. umsebenzi wokukhweza nokwehlisa.

Ukusetshenziswa kanye nesakhiwo se-wrench esindisa abasebenzi: i-wrench-saving wrench iwuhlobo olusha lwe-dissembly yezandla esebenza kahle kakhulu kanye nethuluzi lokuhlanganisa.Kuyidivayisi yokwehlisa isivinini ehlanganisa umugqa owodwa noma eminingi yeplanethi kanye ne-clutch eqondiswa kabili.Ngokufaka i-torque encane, ingakhiqiza i-torque enkulu, esindisa abasebenzi kumphathi wamandla, futhi abanye abantu bayibiza ngokuthi i-booster wrench.Ngokomgomo wokongiwa kwamandla, ukonga abasebenzi, ukonga abasebenzi, isikrufu esisindisa abasebenzi ngokusebenzisa iplanethi ye-platoon deceleration, thola i-torque eyanele, yonga amandla, kodwa ijubane elilahlekile.Umzamo owengeziwe kunokwehlisa ijubane, isivinini siyanensa.Ekwakheni isikrufu esisindisa umsebenzi noma ukuthenga isikrufu esisindisa abasebenzi, kufanele sinake ngokugcwele ubudlelwano phakathi kokulondoloza abasebenzi kanye nesivinini, sikhethe isilinganiso esifanele sokudlulisela.Kufanele siphathe ngendlela efanele ubudlelwano phakathi kwalokhu okubili okusetshenziswayo, isibonelo, okusetshenziselwa ukususa amabhawodi (inadi elikhulu, isikulufu lapho kufinywa) isikrufu sokusebenza kuphela, bese sishintshwa ngomunye isikrufu esijwayelekile;ngenqubo yokuhlanganisa, qala usebenzise izikrufu zesikulufu amabhawudi kuze kube manje lapho kufanele khona, kanye nesikhathi sokucubungula sokulayishwa kwangaphambili kwesidingo sokusebenza.Umzamo wokulondoloza isikrufu uthuthukiswe kuyunithi yezempi.Ngokwesakhiwo, kunezigaba ezimbili ngokuyisisekelo: eyodwa iwumshini we-2K-H.Iqukethe amasondo amabili aphakathi nendawo a, B kanye nodonga olujikelezayo H. Inezinzuzo zokwenziwa okulula, i-axial dimension encane kanye nokusebenza kahle okuphezulu, futhi iyindlela yokudlulisela iplanethi esetshenziswa kakhulu ekusebenzeni.
