Lub hauv paus ntsiab lus ntawm ntswj ntsia hlau
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub hau ntswj yog lub log-axle, uas yog, lub zog ua haujlwm ntawm lub log. Thaum qhov sib piv ntawm lub vojvoog ntawm lub log thiab lub vojvoog ncej loj dua, kev siv zog tau txais kev cawmdim, yog li qhov tuab ntawm lub hau ntswj, qhov kev siv zog tsawg dua nws siv.
Qhov sib txawv ntawm lub hau ntswj thiab lub hau ntswj
Lub hau ntswj yog lub hau ntswj nrog lub hau uas tshem tau thiab hloov tau, thaum lub hau ntswj feem ntau yog tag nrho nrog cov hniav uas tsis tuaj yeem tshem tau. Kuj tseem muaj qee cov ntsia hlau ntsia hlau uas tuaj rau hauv daim ntawv ntawm cov ntsia hlau ntsia hlau, uas yog ib lub teeb uas muaj ob lub hau ntsia hlau thiab ntau hom ntsia hlau ntsia hlau.
Qhov sib txawv ntawm lub hau ntswj thiab lub hau ntswj
Lub hau ntswj thiab lub hau ntswj yog tib yam, thiab lub hau ntswj yog lub npe scientific ntawm lub hau ntswj. Tsis muaj qhov sib txawv ntawm ob. Qhov tseem ceeb tshaj plaws yog cov lus ntawm cov cheeb tsam sib txawv muaj cov npe sib txawv rau cov ntsia hlau.
Dab tsi yog qhov tseem ceeb ntawm cov screwdrivers:
Ordinary screwdriver: Feem ntau cov ntsia hlau ntsia hlau, haum rau siv nyob rau hauv ntau qhov chaw, nrog txawv specifications xws li ntev thiab thickness.
Precision screwdrivers: saib cov ntsia hlau, cov pob zeb diamond me me, cov xov tooj ntawm tes ntsia hlau, thiab lwm yam, feem ntau yog siv los kho cov cuab yeej precision thiab muaj qhov me me.
Combination screwdriver: Lub taub hau ntsia hlau thiab ntsia hlau ntsia hlau tuaj yeem sib cais. Thaum txhim kho ntau hom screws, koj tsuas yog yuav tsum tau hloov lub ntsis taub hau.
Hluav taws xob cov ntsia hlau: Siv lub tshuab hluav taws xob los hloov cov kev sib hloov ntawm tib neeg txhais tes los nruab thiab tshem tawm cov ntsia hlau, feem ntau yog cov khoom siv hluav taws xob sib txuas.
Pneumatic screwdriver: siv cov cua compressed ua lub zog ua haujlwm. Nws yog ceev, nyab xeeb thiab anti-static thaum siv.
Yuav ua li cas xaiv lub hau ntswj
Saib ntawm kev thov
Ua ntej yuav cov ntsia hlau ntsia hlau, koj yuav tsum xub qhia meej koj cov kev xav tau, vim tias muaj ntau hom ntsia hlau, thiab cov ntsia hlau sib txawv yuav raug siv rau cov kev xav tau sib txawv. Yog hais tias nws yog siv rau tsev neeg, tsuas yog yuav ib tug dog dig screwdriver set. Yog tias nws yog siv rau kev tshaj lij, Koj yuav tsum xaiv cov khoom tsim nyog ntsia hlau thiab cov ntsia hlau me me raws li txoj haujlwm xav tau.
