Thatha indophi yesandla esinamandla yaseJapan njengesibonelo. Ithembele kubhuleki othomathikhi ukubona ukuzikhiya ngokwakho kwewinji yesandla, futhi ukubopha okuzenzakalelayo kwamukela indlela yokukhiya kabili, engeke idale umthelela engalweni yamabhuleki ngaphandle kokunyathela amabhuleki, ngakho-ke ngokuyinhloko siyayethula The Double locking mechanism. Umshini okhiya kabili wakhiwe nge-reel ekhethekile yokugcina ama-windings angeziwe kanye nepuleti lethu eliyingqayizivele lentambo okusetshenzwa kulengwa kulo ukuqinisekisa ukuphepha nokuzinza.
Eyodwa. Zungezisa isibambo ngokwewashi, izikulufo ezintathu zizoqinisa isondo bamba futhi bamba. Ulwelwesi lwamabhuleki luzohlanganiswa negiya le-ratchet bese umthwalo uphakanyiswa.
ezimbili. Lapho umthwalo wehlisiwe, amandla akhululiwe azosebenza esondweni lokubamba futhi akhulule isikulufa esintathu. Ukushintshanisa isibambo ngokuphikisana newashi kuzokhulula isikulufu-ntathu, kuzoba negebe elifanele phakathi kukalayini wamabhuleki nomugqa, futhi umthwalo ungancishiswa nganoma yisiphi isivinini.
ezintathu. Enqubeni yokuphakamisa noma yokumisa ukwehla, i-tumbler ibamba umhlanga bese iyeka ukuhamba nganoma yisiphi isikhathi.
ezine. Izikulufo ezintathu ezisetshenziselwa isondo bamba futhi bamba zihlinzeka ukuqina ngempumelelo nge iphimbo elincane. Ngaphezu kwalokho, ukuhola kukhulu kathathu, futhi ijubane lokuqinisa nokukhulula izikulufo liyashesha, ngakho-ke liqinisekisa isenzo esisheshayo sebhuleki lokukhanda.
