Ubusazi na ukuba ukusetyenziswa kokuqala okwaziwayo kweizikrufuzenzeka ngexesha lamaGrike amandulo? Babesebenzisa izikrufu kwizixhobo zokucinezela iminquma neediliya, ubungqina bobuchule babo kunye nobuchule babo. Ukususela ngoko, izikrufu ziye zaguquka zaba yenye yezona zinto zibalulekileyo nezisetyenziswa kakhulu kwizixhobo zobugcisa ezenziweyo namhlanje.
Izixhobo zokubopha ziye zatshintsha kakhulu ngokuhamba kwexesha, zineentlobo ngeentlobo zeemilo, ubungakanani, iindlela, kunye nezixhobo ezikhoyo kwimarike. Xa ukhetha isixhobo sokubopha esiza kusetyenziselwa isicelo sakho, enye yezona zinto zibalulekileyo ekufuneka uziqwalasele luhlobo lwentloko eza kuba nayo isikrufu.
Intloko yesikrufu ibalulekile ngezizathu ezahlukeneyo. Imisela indlela yokuqhuba okanye yokujika isikrufu, kwaye ikwachaphazela ubuhle kunye nokusebenza kwemveliso yokugqibela. Ke ngoko, ukuqonda iintlobo ezahlukeneyo zeentloko zesikrufu kunye neenzuzo zazo kubalulekile ekwenzeni ukhetho olunolwazi.
Uhlobo olunye olusetyenziswa kakhulu lwentloko yesikrufu yiPhillips head. Yaphuhliswa ngeminyaka yoo-1930 nguHenry F. Phillips, ine-cross-shaped recess evumela iPhillips screwdriver ukuba ibambeke ngokukhuselekileyo. Uyilo lwayo lwenza kube lula ukuhambisa i-torque, kunciphisa amathuba okutyibilika nokuqinisekisa uqhagamshelo oluthembekileyo. Intloko yePhillips iye yanda kwiindawo ezininzi zoshishino nakwiindawo zasekhaya.
Enye intloko yesikrufu edumileyo yiflathead, eyaziwa ngokuba yiskrufu esinezikhewu. Inesithuba esinye esithe tye phezulu, esivumela ukuba iqhutywe kusetyenziswa iskrufu esinezikhewu. Nangona isenokungabi nakho ukubamba okufanayo nezinye iintloko zesikrufu, isasetyenziswa kakhulu ekusebenzeni ngomthi, ekuhlanganiseni ifenitshala, nakwezinye iindlela zemveli. Ukulula kunye nokufikeleleka kweflathead kunegalelo ekuthandweni kwayo okuqhubekayo.
Kutshanje, intloko yeTorx ifumene udumo olukhulu. Yaphuhliswa yinkampani yeCamcar Textron ngo-1967, inomqolo omile okweenkwenkwezi ezintandathu. Olu yilo lubonelela ngokudluliselwa kwe-torque okuphuculweyo, okunciphisa umngcipheko wokukrazulwa okanye ukuphuma. Intloko yeTorx isetyenziswa kakhulu kumashishini apho kufuneka khona ukusetyenziswa kwe-torque echanekileyo nephezulu, njengeemoto, izixhobo ze-elektroniki, kunye neenqwelo moya.
Kwizicelo apho ubuhle bubalulekile khona, isikrufu sentloko yesokhethi sibonisa inkangeleko ethambileyo nethambileyo. Sinentloko esisilinda enesokhethi yangaphakathi ye-hex egobileyo, evumela ukuba iqhutywe kusetyenziswa isikrufu se-Allen okanye isitshixo se-hex. Isikrufu sentloko yesokhethi ngokuqhelekileyo sisetyenziswa koomatshini, kwiimoto, nakwifenitshala yexabiso eliphezulu, apho kufuneka inkangeleko ecocekileyo nelungeleleneyo.
Ngaphandle kwezi ndlela zidumileyo, kukho ezinye iintlobo ezininzi zeentloko zezikrufu ezikhoyo, nganye ineenzuzo zayo ezikhethekileyo. Umzekelo, iintloko ze-square drive, i-Pozidriv, kunye ne-hexagonal zisetyenziswa kakhulu kumashishini athile okanye kwizicelo ezikhethekileyo.
Ukuqukumbela, ukukhetha isincamathelisi esifanelekileyo kwisicelo sakho kubandakanya ukuqwalasela izinto ezahlukeneyo, ezinje ngobukhulu, izinto ezisetyenzisiweyo, kunye nesitayile. Nangona kunjalo, uhlobo lwentloko esiza kuba nayo isikrufu lubaluleke kakhulu, njengoko simisela indlela yokuqhuba kwaye sinokuchaphazela ukusebenza kunye nokubonakala kwemveliso yokugqibela. Nokuba ukhetha intloko yePhillips evavanyiweyo neyinyani, intloko yesiqhelo ethe tyaba, okanye ukuchaneka kwentloko yeTorx, ukuqonda iintlobo ezahlukeneyo zeentloko zesikrufu kuya kuqinisekisa ukuba wenza isigqibo esinolwazi xa kufikwa ekukhetheni isincamathelisi esifanelekileyo kwiimfuno zakho.
