Zomangira zodzibowolera zokha komanso zodzipangira zokha zimatha kubowoledwa, kuponyedwa, ndi kutsekedwa molunjika pazikhazikiko ndi zida zoyambira nthawi imodzi komanso mwachangu. Amatha kubowoleredwa mwachangu komanso mwachangu ndikumangika mwachindunji, zomwe zimapulumutsa nthawi yomanga kwambiri komanso kupititsa patsogolo luso la zomangamanga. Kuchita bwino komanso kupindula kwachuma. Zigawo zolumikizidwa zomwe zimakongoletsedwa ndi zomangira zodzibowolera zokha zimakhala ndi mphamvu zomangirira zolimba, mphamvu zomangirira kwambiri, komanso kukhazikika kwazigawo zolumikizidwa.

Kusiyanitsa pakati pa zomangira zodzibowola ndi zomangira pawokha ndi zomangira wamba zodzimenya ndikuti polumikiza, zomangira wamba zodzibowolera ziyenera kudutsa njira ziwiri: kubowola (kubowola mabowo pansi) ndikugogoda (kuphatikiza zolumikizira), pomwe zomangira zokha. -kubowola ndi zomangira pawokha zomangira Pamene screw chikugwirizana, njira ziwiri za kubowola ndi pogogoda mwachindunji pamodzi ndi kutha nthawi imodzi. Zomangira za Drill tail zimadziwika ndi torque yotsika komanso kutseka kwakukulu. Amagwira ntchito bwino kuposa zomangira wamba zodzibowola komanso zodzibowolera zokha ndipo zitha kugwiritsidwa ntchito m'malo mwa zomangira zamakina.

Kubowola mchira zomangira makamaka ntchito kulumikiza ndi kukonza zina woonda mbale mbale, monga kugwirizana pakati mbale zitsulo mtundu ndi mtundu zitsulo mbale, kugwirizana pakati mbale mtundu zitsulo ndi purlins, khoma matabwa, etc. malowedwe awo mphamvu zambiri si upambana 6mm. , ndipo kuchuluka kwake sikudutsa 12mm. Kubowola mchira zomangira chimagwiritsidwa ntchito ndipo ndi oyenera unsembe wa mbale zitsulo zosapanga dzimbiri, mbale zitsulo zitsulo, malata zitsulo mbale, kapena ntchito zina zomangamanga, m'nyumba ndi panja unsembe wa makoma zitsulo nsalu yotchinga, partitions kuwala zitsulo, zitseko pulasitiki zitsulo ndi mazenera, etc. , ndikuyika zitsulo zachitsulo, mbale zachitsulo ndi zitsulo zina. Ndi zina zitsulo dongosolo unsembe. Ntchito zophatikizira wamba monga zipinda zamagalimoto, zotengera, zomangira zombo, zida zamafiriji, ndi uinjiniya wa chilengedwe ndizosasiyanitsidwa ndi zomangira zoboola mchira.
