Mitundu Yodziwika Kwambiri ya Mutu Wopanga

Kodi mukudziwa kuti kugwiritsa ntchito koyamba kodziwika bwino kwazomangiraKodi chinachitika nthawi ya Agiriki akale? Ankagwiritsa ntchito zomangira m'zida zosindikizira maolivi ndi mphesa, umboni wa luso lawo komanso luso lawo. Kuyambira nthawi imeneyo, zomangira zasanduka chimodzi mwa zida zofunika kwambiri komanso zogwiritsidwa ntchito kwambiri masiku ano.

Zipangizo zomangira zasintha kwambiri pakapita nthawi, ndipo pali mitundu yosiyanasiyana ya mawonekedwe, kukula, masitayelo, ndi zipangizo zomwe zikupezeka pamsika. Mukasankha chomangira chomwe mungagwiritse ntchito, chimodzi mwazinthu zofunika kwambiri kuganizira ndi mtundu wa mutu womwe screw idzakhala nayo.

Mutu wa sikuru ndi wofunikira pazifukwa zosiyanasiyana. Umasankha njira yoyendetsera kapena kutembenuza sikuru, ndipo umakhudzanso kukongola ndi magwiridwe antchito a chinthu chomaliza. Chifukwa chake, kumvetsetsa mitundu yosiyanasiyana ya mitu ya sikuru ndi ubwino wake ndikofunikira popanga chisankho chodziwa bwino.

Mtundu umodzi wa mutu wa screwhead womwe umagwiritsidwa ntchito kwambiri ndi mutu wa Phillips. Wopangidwa m'ma 1930 ndi Henry F. Phillips, uli ndi chopondera chooneka ngati mtanda chomwe chimalola screwdriver ya Phillips kugwira ntchito motetezeka. Kapangidwe kake kamalola kutumiza mphamvu bwino, kuchepetsa kuthekera kwa kutsetsereka ndikutsimikizira kulumikizana kodalirika. Mutu wa Phillips wakhala wofala kwambiri m'mafakitale ambiri ndi ntchito zapakhomo.

Mutu wina wotchuka wa screwhead ndi flathead, womwe umadziwikanso kuti slotted screw. Uli ndi malo amodzi owongoka pamwamba, zomwe zimathandiza kuti uzitha kuyendetsedwa pogwiritsa ntchito screwdriver ya flathead. Ngakhale kuti sungapereke kugwira kofanana ndi mitu ina ya screwhead, umagwiritsidwabe ntchito kwambiri popanga matabwa, kupanga mipando, ndi ntchito zina zachikhalidwe. Kusavuta kwa flathead komanso mtengo wake zimathandiza kuti ipitirire kutchuka.

Posachedwapa, mutu wa Torx watchuka kwambiri. Wopangidwa ndi kampani ya Camcar Textron mu 1967, uli ndi malo otsetsereka ngati nyenyezi zisanu ndi chimodzi.

Mutu wa Torx umagwiritsidwa ntchito kwambiri m'mafakitale komwe kumafunika kugwiritsa ntchito mphamvu yolondola komanso yapamwamba, monga magalimoto, zamagetsi, ndi ndege.

Pa ntchito zomwe kukongola ndikofunikira, sikuluu ya mutu wa soketi imawoneka yokongola komanso yowala. Ili ndi mutu wozungulira wokhala ndi soketi yamkati yozungulira, zomwe zimapangitsa kuti iyendetsedwe pogwiritsa ntchito kiyi ya Allen wrench kapena hex. Sikuluu ya mutu wa soketi imagwiritsidwa ntchito kwambiri pamakina, magalimoto, ndi mipando yapamwamba, komwe kumafunika mawonekedwe oyera komanso osalala.

Kupatula mitundu yotchuka iyi, pali mitundu ina yambiri ya mitu ya screw yomwe ilipo, iliyonse ili ndi ubwino wake wapadera. Mwachitsanzo, mitu ya square drive, Pozidriv, ndi hexagonal imagwiritsidwa ntchito kwambiri m'mafakitale enaake kapena ntchito zapadera.

Pomaliza, kusankha chomangira choyenera kugwiritsa ntchito kumaphatikizapo kuganizira zinthu zosiyanasiyana, monga kukula, zinthu, ndi kalembedwe. Komabe, mtundu wa mutu womwe screw idzakhala nawo ndi wofunika kwambiri, chifukwa umatsimikizira momwe imayendetsera ndipo ungakhudze magwiridwe antchito ndi mawonekedwe a chinthu chomaliza. Kaya mwasankha mutu wa Phillips woyesedwa bwino, mutu wachikhalidwe, kapena kulondola kwa mutu wa Torx, kumvetsetsa mitundu yosiyanasiyana ya mitu ya screw kudzatsimikizira kuti mwasankha bwino posankha chomangira choyenera zosowa zanu.
