Clamp - ubwoko bwanyuma nibikorwa byubwoko bukoreshwa cyane mubikorwa byanyuma. Zigizwe ahanini nuburyo bwo kohereza hamwe nuburyo bwo gutwara, busa nintoki yoroshye. Bashobora gufata ibintu binyuze mu gufungura no gufunga icyerekezo cyo gufata ukuboko. Guswera - ubwoko bwanyuma bukoresha cyane cyane guswera kugirango ubone ibikoresho, bigatuma biba byiza gufata ibintu bito no gutanga ibintu byinshi. Impamyabumenyi yihariye irangiza ni ibikoresho byikora cyane birashobora kurangiza byoroshye imirimo itandukanye.
