Ityhubhu yesikwereluhlobo lwemathiriyeli eqhele ukusetyenziswa kushishino lolwakhiwo lwemizi-mveliso, enemfuno enkulu.Kukho iimveliso ezininzi zeetyhubhu kwimarike, kwaye umgangatho awulingani.Ingqalelo kufuneka ihlawulwe kwindlela yokukhetha xa ukhetha:
1. Jonga ubungakanani
Isixhobo sokulinganisa i-vernier clamp singasetyenziselwa ukulinganisa ngokulula ukuba ubungakanani bokwenene bumalunga nenkcazo enye okanye buncinci kunobukhulu obuphawulweyo.Ngokuqhelekileyo, akukho mahluko mkhulu phakathi kweetyhubhu zesikwere ezilungileyo;Ukongeza, kufuneka kuqatshelwe ukuba eminye imibhobho yesikwere ekumgangatho ophantsi iya kukhohlisa umbono wabantu ngokubetha umlomo.Ngoko ke, ubuso bokugqibela bombhobho wensimbi kufuneka bube yi-oval flat, ngelixa isiphelo sobuso bezinto eziqhelekileyo kufuneka sibe setyhula.
2. Jonga intsebenzo
Ityhubhu yesikwere ineempawu ezithile zokuqina kunye noxinzelelo, ngoko ke sinokuyiqwalasela le miba xa ukhetha ityhubhu yesikwere: amandla okuqina kukusebenza kweityhubhu yesikwereisiseko, kwaye ubukhulu bokuqina bokuqina kuthetha ukuba ngcono ukusebenza kombhobho yesikwere;Uqwalaselo olubanzi luya kuhlawulwa kwakhona kuxhathiso loxinzelelo kunye nokumelana nokugoba.
3.Jonga umgangatho womphezulu
Umgangatho womphezulu ophantsiiityhubhu zesikwereihlwempuzekile ngenxa yokuqengqeleka ngemathiriyeli ekrwada, kwaye kaninzi ineziphene ezifana nokukhuhla kwaye banemvakalelo erhabaxa iyonke.Ezinye iintsimbi ezincinci zinombala obomvu ngenxa yobushushu obunganeleyo kunye nesantya sokujikeleza;Umgangatho ophezulu we-square tube ufanelekile, ngaphandle kweziphene ezicacileyo, kwaye umbala umhlophe kwaye uqhakazile.
4.Jonga ukupakishwa
Uninzi lwemibhobho ye-square ye-rectangular eqhelekileyo ipakishwe kwiingxowa ezinkulu xa zihanjiswa kumzi-mveliso.Iiplati zetsimbi ezihambelana nezinto zangempela zixhonywe kwiingxowa zetsimbi, ezibonisa umenzi, uphawu lwensimbi, inombolo yebhetshi, inkcazo kunye nekhowudi yokuhlola, njl.Ingqwalasela ekhethekileyo kufuneka ihlawulwe kwiimveliso zetyhubhu ezinoxande kunye neenyanda ezincinci (malunga neenyanda ezilishumi) okanye ngobuninzi, ngaphandle kweelebula zetsimbi kunye neziqinisekiso zokuqinisekisa umgangatho.
