E like me ka ʻike a nā mea a pau, ʻo ka hapa nui o ka puʻupuʻu kaʻa kaʻa inā hui a wehe ʻia a mālama ʻia, ma waho aʻe o ka ʻenehana i kēia manawa o ka wīwī pneumatic wrench he spanner wrench a me nā puka puka i hoʻomaʻemaʻe maoli ʻia, ʻaʻole lawa ka hoʻohana ʻana ʻaʻole i kūpono i ka nati kaʻa no ka. ka hana kau ana a me ka hemo ana.

ʻO ka hoʻohana ʻana a me ke ʻano o ka wīwī hoʻopakele hana: ʻo ka wili mālama hana he ʻano hou o ka hoʻokaʻawale lima hana kiʻekiʻe a me ka mea hana hui.He mea hoʻoemi hoʻokahi a ʻoi aʻe paha nā lālani honua a me ka paʻa pālua.Ma ka hoʻokomo ʻana i kahi torque liʻiliʻi, hiki iā ia ke hana i kahi torque puka nui, ʻo ia ka mea e mālama ai i ka hana no ka mea paʻa ikaika, a kapa kekahi poʻe iā ia he wīwī booster.E like me ka loina o ka conservation o ka ikehu, hana-ho'ōla, hana-ho'ōla, hana-ho'ōla wrench ma ka planetary platoon deceleration, loaa lawa torque, e hoola i ka ikaika, akā, nalowale wikiwiki.ʻOi aku ka ikaika ma mua o ka deceleration, lohi ka wikiwiki.I ka hoʻolālā ʻana i ka wili hoʻopakele hana a i ʻole ke kūʻai ʻana i ka wili hoʻopakele hana, pono mākou e hoʻolohe piha i ka pilina ma waena o ka mālama ʻana i ka hana a me ka wikiwiki, e koho i ka ratio hoʻouna kūpono.Pono mākou e mālama pono i ka pilina ma waena o nā mea ʻelua i hoʻohana ʻia, no ka laʻana, hoʻohana ʻia no ka wehe ʻana i nā bolts (ka nut nui, ka wili i ka wā e wili ai) wale nō ka laborsaving wrench, a laila hoʻololi ʻia me ka wrench general;no ke kaʻina hana, e hoʻohana mua i nā kī wiliwili a hiki i ka hopena i kūpono i kahi a hiki i kēia manawa, a me ka hana hoʻopakele wrench preloading hana manawa o ka pono.Ua hoʻomohala ʻia ka wīwī hoʻōla ma ka pūʻali koa.Ma ke ʻano, ʻelua mau ʻāpana: ʻo ka mīkini 2K-H kekahi.Loaʻa iā ia nā huila waena ʻelua a, B a me ka paia rotatable H. Loaʻa iā ia nā pōmaikaʻi o ka hana maʻalahi, liʻiliʻi liʻiliʻi axial a me ka hana kiʻekiʻe, a ʻo ia ka mea i hoʻohana nui ʻia i ka planetary transmission i ka hana.

ʻO kēia ka mea i ʻōlelo ʻia e JIAYE laborsaving wrench QL-58A:
