Ua ntej, hauv qab ntawm lub thawv yas no tau raug txhawb kom ruaj khov thiab ruaj khov. Tib lub sijhawm, nws kuj siv txoj kev tsim kom tsis txhob plam thiab tsis txhob poob, uas ua rau nws yooj yim rau kev sib sau ua ke. Qhov thib ob, lub thawv tag nrho yog tsim los ntawm lub qhov (pin shaft), uas muaj peev xwm nqa tau zoo. Lub peev xwm thauj khoom ntau dua 3 npaug ntawm cov khoom zoo sib xws, thiab nws tuaj yeem sib sau ua ke nrog 5 txheej yam tsis muaj kev hloov pauv. Peb, kev tsim ntawm lub thav duab ntawm lub thawv yas no yog du, uas yog qhov zoo rau kev luam ntau lo lus rau kev sib txawv yooj yim, thiab muaj cov txiaj ntsig tshaj tawm.

Cov thawv ntawv folding tsis yog tsuas yog yooj yim rau kev khaws cia, tab sis kuj muaj cov qauv tsim zoo. Tom qab siv dua tshiab lawm, lawv siv tau ua cov khoom siv rov ua dua tshiab thiab txuas ntxiv mus rau hauv kev tsim khoom. Qhov no tsis yog tsuas yog txo cov nqi thauj mus los xwb, tab sis kuj ua lub luag haujlwm zoo hauv kev txhawb nqa kev tiv thaiv ib puag ncig.
