Lub shackle yog ib qho cuab yeej siv los qhib cov saw lossis hlua txuas thiab feem ntau siv hauv kev nqa cov haujlwm, tub rog, pej xeem aviation, thiab tsheb. Nws feem ntau muaj ob ntu: lub shackle nws tus kheej thiab ib qho kev khiav hauj lwm pas nrig.
Shackles sib txawv hauv cov duab thiab qhov loj me rau qhov sib txawv. Hauv kev lag luam, qee qhov shackles yuav loj thiab xav tau cov cuab yeej tshwj xeeb los ua haujlwm, thaum lwm tus me dua thiab tuaj yeem ua haujlwm ntawm tes. Piv txwv li, thaum tsim cov hlau loj loj, cov shackles loj yuav tsum tau txuas thiab ruaj ntseg chains lossis hlua.
Kev khiav hauj lwm pas nrig kuj yog ib feem tseem ceeb ntawm shackle. Kev khiav hauj lwm pas nrig tuaj yeem txuas nrog lub shackle los muab kev tswj thiab kev ua haujlwm zoo dua. Qhov ntev thiab cov duab ntawm lub levers sib txawv rau ntau lub hom phiaj, piv txwv li, thaum dismantling ntau yam thiab accessories ntawm ib lub dav hlau, cov levers yuav siv tau los securely tso lub shackle thiab ua kom lub tshem tawm ua hauj lwm yooj yim dua thiab meej.
