1. Thaum ntxov tsim thiab siv wrenches
Lub hauv paus chiv keeb ntawm wrenches tuaj yeem taug qab mus rau lub sijhawm qub. Tus tsim thawj yog yooj yim heev thiab yog siv los disassemble ntoo rooj tog thiab machinery. Nrog rau kev nce qib ntawm Industrial Revolution, tsim thiab siv cov wrenches maj mam hloov. Nyob rau hauv lub lig 18th caug xyoo, lub nce ntawm lub British Industrial Revolution txhawb lub industrialization ntawm wrenches. Thaum xub thawj, nws yog xuas tes ua, thiab tom qab ntawd maj mam tsim mus rau hauv kev tsim khoom siv tshuab.
2. Cov txheej txheem ntawm wrenches thiab qhov tshwm sim ntawm patents
Thaum pib ntawm lub xyoo pua puv 19, Tebchaws Asmeskas tau tsim kev lag luam kev lag luam khoom siv tshuab, uas txhawb kev txhim kho kev lag luam wrench. Wrenches tuaj yeem ua tus qauv, meej, thiab tsim tawm ntau, yog li txo cov nqi thiab txhim kho kev ua haujlwm. Thaum kawg ntawm lub xyoo pua puv 19, kev lag luam kev sib tw rau cov wrenches tau nce zuj zus, thiab cov neeg tsim khoom tau pib siv cov cuab yeej tshiab los ua ib qho ntawm lawv cov tswv yim kom tau txais kev sib tw ua lag luam. Xyoo 1875, John Morris Stilleven tau tsim cov ciaj ntswj kho tau, uas yog thawj tus ciaj ntswj patent. Lub patent pom qhov sib txawv ntawm qhov sib txawv nruab nrab ntawm lub taub hau ntawm tus ciaj ntswj. Qhov kev nce qib hauv cov ntsiab lus tau dhau los ua qhov kev xav tau ntawm kev lag luam dav dav, thiab tseem txhawb kev txhim kho cov wrenches.
3. Cov qauv tsim ntawm niaj hnub wrenches
Kev tsim cov wrenches niaj hnub tau ua tiav qib siab ntawm kev tsim qauv. Ntau hom wrenches (xws li phau ntawv wrenches, hluav taws xob wrenches thiab pneumatic wrenches) muaj lawv tus kheej cov qauv tsim tshwj xeeb. Piv txwv li, cov qauv tsim ntawm phau ntawv wrenches suav nrog qhov ntev, qhov dav, tuab, cov khoom siv, kev kho deg, thiab lwm yam ntawm cov ciaj ntswj; cov qauv tsim ntawm lub tshuab hluav taws xob muaj xws li lub cev muaj zog, ceev, lub zog, lub peev xwm roj teeb, lub sijhawm them nyiaj, thiab lwm yam; cov qauv tsim ntawm pneumatic wrenches muaj xws li cua siab, cua khiav, ceev, torque, thiab lwm yam.
4. Qhov tseem ceeb ntawm tus qauv tsim ntawm wrenches
Tus qauv tsim ntawm wrenches pab txhim kho qhov zoo thiab kev ua haujlwm ntawm cov khoom, txo cov nqi tsim khoom, thiab txhim kho kev tsim khoom. Nws kuj pab tau cov neeg siv khoom yooj yim xaiv thiab siv cov wrenches uas haum rau lawv. Tsis tas li ntawd, tus qauv tsim qauv kuj tuaj yeem txhawb nqa kev noj qab haus huv ntawm kev lag luam wrench thiab txhim kho kev sib tw ntawm tag nrho kev lag luam.
5. Yav tom ntej tiam sis nyob rau hauv tus qauv tsim ntawm wrenches
Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, tus qauv tsim ntawm cov wrenches yuav dhau los ua ntau dua thiab nyuaj. Piv txwv li, cov wrenches yav tom ntej tuaj yeem siv cov khoom siv thev naus laus zis ntau dua thiab cov txheej txheem tsim khoom los txhim kho lawv lub zog, kav ntev thiab kev nplij siab; Nyob rau tib lub sijhawm, kev tsim cov wrenches tseem yuav tau them nyiaj ntau rau ergonomics los txhim kho lawv txoj kev nplij siab thiab kev ua haujlwm. Tsis tas li ntawd, nrog rau kev txhim kho ntawm cov cuab yeej ntse, wrenches yav tom ntej yuav dhau los ua neeg ntse dua. Piv txwv li, cov xwm txheej ua haujlwm thiab kev ua haujlwm ntawm tus ciaj ntswj tuaj yeem tswj tau thiab saib xyuas los ntawm lub xov tooj ntawm tes APP.
