Amatwi yo gutwi agizwe na bande (mubisanzweibyuma) muri byo harimo "amatwi" cyangwa byinshi byo gufunga.

Clamp ishyirwa hejuru yumutwe wa hose cyangwa umuyoboro kugirango uhuze kandi mugihe buri gutwi gufunze munsi yugutwi nigikoresho cyihariye cya pincer, kirahinduka burundu, gikurura bande, kandi bigatuma umurongo ukomera hafi ya hose. .Ingano ya clamp igomba guhitamo kuburyo ugutwi (s) gufunze hafi mugushiraho.

Ibindi biranga ubu buryo bwa clamp harimo: ubugari bwagutse bwagutse, bugamije gutanga compression yibanze ya hose cyangwa tube;natamper resistance, kubera ihinduka rihoraho rya "ugutwi" kwa clamp.Niba gufunga clamp "ugutwi (gutwi)" bikorwa mubyifuzo byabashinzwe gukora, mubisanzwe bitanga imbaraga zihoraho, ingaruka zo gufunga ntabwo zumva neza uburyo bwo kwihanganira ibice.

Bimwe muri ibyo bisate biranga ibimera bigamije gutanga ingaruka zimpeshyi mugihe diameter ya hose cyangwa imiyoboro ya kontaro cyangwa yagutse kubera ingaruka zubushyuhe cyangwa ubukanishi.
