Ubuwazi ukuthi ukusetshenziswa kokuqala okurekhodiwe kwe-izikulufuKwenzeka ngesikhathi samaGreki asendulo? Babesebenzisa izikulufo kumadivayisi ukucindezela iminqumo namagilebhisi, ubufakazi bobuhlakani babo kanye nobuhlakani babo. Kusukela ngaleso sikhathi, izikulufo ziye zashintsha zaba enye yezingcezu zehadiwe ezibaluleke kakhulu nezisetshenziswa kabanzi ezikhiqizwa namuhla.
Ihadiwe ye-fastener ishintshe kakhulu ngokuhamba kwesikhathi, inezinhlobo eziningi zezimo, osayizi, izitayela, kanye nezinto ezitholakala emakethe. Uma ukhetha i-fastener yohlelo lwakho lokusebenza, esinye sezici ezibaluleke kakhulu okufanele uzicabangele uhlobo lwekhanda isikulufu esizoba nalo.
Ikhanda lesikulufu libalulekile ngezizathu ezahlukahlukene. Linquma indlela yokushayela noma yokujika isikulufu, futhi lithinta nobuhle kanye nokusebenza komkhiqizo wokugcina. Ngakho-ke, ukuqonda izinhlobo ezahlukene zamakhanda esikulufu kanye nezinzuzo zawo kubalulekile ekwenzeni ukukhetha okunolwazi.
Uhlobo olulodwa oluvame ukusetshenziswa lwekhanda lesikulufo yikhanda likaPhillips. Lakhiwa ngawo-1930 nguHenry F. Phillips, linesikhala esinobunjwa obuhlukahlukene esivumela i-screwdriver yePhillips ukuthi ibambeke ngokuphephile. Umklamo wayo wenza kube lula ukudlulisa i-torque, kunciphisa amathuba okushelela nokuqinisekisa ukuxhumana okuthembekile. Ikhanda likaPhillips selivele likhona ezimbonini eziningi nasezinhlelweni zasekhaya.
Elinye ikhanda lesikulufo elidumile yi-flathead, eyaziwa nangokuthi isikulufo esinezimbobo. Inesikhala esisodwa esiqondile phezulu, okwenza ukuthi iqhutshwe kusetshenziswa isikulufo esinezimbobo. Nakuba ingase ingabi nokubamba okufanayo nezinye izikulufo, isasetshenziswa kakhulu ekusebenzeni ngokhuni, ekuhlanganiseni ifenisha, nakwezinye izinhlelo zokusebenza zendabuko. Ukulula kanye nokungabizi kwe-flathead kunegalelo ekuthandweni kwayo okuqhubekayo.
Muva nje, ikhanda le-Torx selithole ukuthandwa okwandayo. Lasungulwa yinkampani i-Camcar Textron ngo-1967, line-recess efana nenkanyezi enamaphuzu ayisithupha. Lo mklamo uhlinzeka ngokudluliselwa kwe-torque okuthuthukisiwe, okunciphisa ingozi yokukhumula noma ukuphuma. Ikhanda le-Torx livame ukusetshenziswa ezimbonini lapho kudingeka khona ukusetshenziswa kwe-torque enembile nephezulu, njengezimoto, izinto zikagesi, kanye nezindiza.
Ngezinhlelo zokusebenza lapho ubuhle bubalulekile khona, isikulufu sesivalo sekhanda lesokhethi sinikeza ukubukeka okubushelelezi nokucwebezelayo. Sinekhanda eliyindilinga elinesokhethi ye-hex yangaphakathi egobile, okuvumela ukuthi liqhutshwe kusetshenziswa isikrufu se-Allen noma ukhiye we-hex. Isikulufu sesivalo sekhanda lesokhethi sivame ukusetshenziswa emishinini, ezimotweni, kanye nasefenisha ephezulu, lapho kudingeka khona ukubukeka okuhlanzekile nokuhlelekile.
Ngaphandle kwalezi zinketho ezidumile, kunezinhlobo eziningi zamakhanda ezikulufo atholakalayo, ngalinye linezinzuzo zalo ezihlukile. Isibonelo, amakhanda e-square drive, i-Pozidriv, kanye namakhanda e-hexagonal avame ukusetshenziswa ezimbonini ezithile noma ezinhlelweni ezikhethekile.
Ekuphetheni, ukukhethwa kwesiqiniseko esifanele sohlelo lwakho lokusebenza kuhilela ukucabangela izici ezahlukahlukene, njengosayizi, izinto zokwakha, kanye nesitayela. Kodwa-ke, uhlobo lwekhanda isiqiniseko esizoba nalo lubaluleke kakhulu, njengoba lunquma indlela yokushayela futhi lungathinta ukusebenza kanye nokubukeka komkhiqizo wokugcina. Kungakhathaliseki ukuthi ukhetha ikhanda le-Phillips elivivinyiwe neliyiqiniso, ikhanda eliyisicaba lendabuko, noma ukunemba kwekhanda le-Torx, ukuqonda izinhlobo ezahlukene zamakhanda esiqiniseko kuzoqinisekisa ukuthi wenza isinqumo esinolwazi uma kuziwa ekukhetheni isiqiniseko esifanele izidingo zakho.
