Chotchinga pampando wanjinga ndi chinthu chomwe chimatchinjiriza mpando wanjinga pa chimango, chomwe nthawi zambiri chimakhala ndi chotchingira chimodzi ndi screw imodzi. Ntchito yake ndikuteteza mpando wapampando pa chimango, kusunga chishalo chokhazikika komanso chotetezeka, ndikulola wokwerayo kusintha kutalika kwa mpando kuti agwirizane ndi zosowa zosiyanasiyana zokwera.
Zingwe zapampando wa njinga nthawi zambiri zimapangidwa ndi zinthu zopepuka monga aluminium alloy kapena carbon fiber kuti muchepetse kulemera kwa njinga. Kukula ndi mawonekedwe a clamp amasiyana malinga ndi chimango, kotero ndikofunikira kuwonetsetsa kuti chotchingiracho chikugwirizana ndi chimango cha njinga posankha imodzi.
Kumangirira kwa clamp kumatheka kudzera mu zomangira chimodzi kapena ziwiri. Zomangirazo zimatha kukhala zomangira za hex kapena zomangira zotulutsa mwachangu, ndi mwayi wokhala wosavuta kusintha ndi kukonza.
Yankho: Chotchingira pampando panjinga ndi chipangizo chomangira mpando wanjinga. Nthawi zambiri imakhala ndi zingwe ziwiri zomwe zimatha kusinthidwa kuti zikhale zolimba pogwiritsa ntchito screw kapena batani lotulutsa mwachangu.
Yankho: Mitundu ya zingwe zapampando wanjinga nthawi zambiri zimayikidwa m'magulu ang'onoang'ono potengera ma clamp awo komanso momwe amasinthira. Mitundu yodziwika bwino imaphatikizira zomangira zamtundu wanthawi zonse komanso zotulutsa mwachangu.
Yankho: Choyamba, muyenera kudziwa kugwirizana pakati pa mpando wanu wa njinga yamoto ndi kukula kwake. Kuphatikiza apo, zinthu ndi makina a clamp ziyenera kuganiziridwanso. Mwachitsanzo, ngati nthawi zambiri mumafunika kusintha kutalika kwa mpando wanu wanjinga, choletsa chofulumira chingakhale chisankho chabwinoko.
Yankho: Kuti musinthe kulimba kwa kampando ka njinga, mutha kugwiritsa ntchito wrench kapena kiyi ya Allen kutembenuza wononga kapena kusintha batani lotulutsa mwachangu. Kuthina kuyenera kukhala kokwanira kuti mpando ukhale wokhazikika, koma osati wothina kwambiri chifukwa ukhoza kuwononga mpanda kapena chotchinga.
