一、Inkcazelo yemveliso: 

Iisarha zesandla ezinqamlezileyo zidla ngokuba nencakuba yesarha, isiphatho, kunye neendawo ezidibanisayo. Incakuba yesarha ngokuqhelekileyo ibhityile, inobubanzi obuphakathi kwaye ibhityile. Uyilo olucalanye luyenza yahluke kwisarha yemveli emacala amabini ngenkangeleko. Isibambo senziwe nge-ergonomics engqondweni, kwaye imilo kunye nobukhulu bayo bufanelekile ukubamba isandla somntu, ukubonelela ngamava okusebenza kakuhle.

二, sebenzisa: 

I-1: Kumsebenzi womthi, iisarha zesandla ezinomphetho omnye zingasetyenziselwa ukusika iinkuni, ukwenza i-mortise kunye nezakhiwo ze-tenon, ukwenza ukukrola okulungileyo, njl.

2:Iisarha zesandla esinomphetho omnye zingasetyenziselwa ukusika imibhobho, ukusika amasebe, ukwenza ifenitshala elula, njl.

3: Iyakwazi ukusika ngokuchanekileyo izixhobo ezahlukeneyo kwaye ivelise iinxalenye zemodeli ezintle, ezibonelela ngokulula kakhulu ukwenza imodeli.

三, Ukusebenza kunenzuzo:

I-1: Ekubeni kukho i-serrations kuphela kwicala elinye, indawo yoqhagamshelwano phakathi kwe-saw blade kunye nezinto eziphathekayo zincinci ngexesha lenkqubo yokusika, okunciphisa ukuchasana kwe-friction, okwenza ukusika kube lula kunye nokuphucula ngakumbi ukuchaneka kokusika.

2:Iisarha zesandla esinomphetho omnye ziyakwazi ukusika ngokufanelekileyo izixhobo zobunzima obahlukeneyo. Ngokuhlengahlengisa i-angle yokusika kunye nokunyanzeliswa, iiplati ezincinci kunye nezityebileyo zinokunqunyulwa ngokulula.

3:  Umqheba wesarha esintlangothi-nye idla ngokuyilwa nomsebenzi ochasene nokutyibilika, onokuphucula ngokufanelekileyo uzinzo lokubamba kunye nokunciphisa ukwenzeka kweengozi ezibangelwa kukutyibilika kwesandla.

四、 Iimpawu zenkqubo

(1) Ukuze kuphuculwe ukunyanzeliswa kokunxiba kunye nokumelana nokugqwala kwe-saw blade, ezinye iisarha zesandla ezinomphetho omnye zisebenzisa izinto ezikhethekileyo ze-alloy ezifana nentsimbi ephezulu, intsimbi ye-tungsten, njl.

(2) Ukuze kuphuculwe ubulukhuni kunye nokuxhatshazwa kwamazinyo e-saw, i-saw blade idla ngokucinywa.

(3) Ukuze kuphuculwe ukusebenza kwe-anti-slip ye-handle, umphezulu wesiphatho udla ngokuphathwa ngonyango oluchasene ne-slip.

(4) Ukuchaneka kwelungiselelo lamazinyo e-saw nakho kubaluleke kakhulu, okuchaphazela ngokuthe ngqo ukusebenza kokusika kunye nobomi benkonzo ye-saw blade.
