20 如以上所簡述的,實現驅動器54的移動係藉由在卡匣 外殼30的凹座140内裝設推動軸環142。當推動軸環142 與驅動纜線50及驅動棘爪156 —起動作時,可讓人推動驅 動器54向前而克服彈簧148向閉合位置偏壓驅動器54的 阻力。更特別的是,驅動棘爪156是可樞轉地安裝於卡匣 外殼30上而可在鎖緊位置(請參考第4圖)與放鬆位置(請 芩考第5圖及第β圖)之間移動。處於鎖緊位置時,驅動棘 爪156有第一末端158,該第一末端158係與在卡匣外殼 30凹座140内形成的推動軸環142嚙合。在嚙合著推動軸 環142的時候,驅動棘爪156可防止推動軸環142與卡匣 外豉30的相對移動。推動軸環142包含座落於驅動纜線 50遠端144的内螺紋160。因此,在驅動棘爪156緊緊地 夾著推動軸裱142的時候,旋轉驅動纜線5〇會使整個卡匣 外殼30向前移動。 當卡匡外殼30到達相對於石占體32的預定點時,驅動 棘爪156 &第二末端162會與末端執行器16的斜坡164嚙 合使它在反時鐘方向旋轉而使驅動棘爪156的第一末端 158移動離開與推動軸環142嗜合著的鎖緊位置。因此, 當驅域線50在卡Ε外殼30内旋轉時, ^卡,殼30遠端移動。藉由加上由推動軸環伸^ 卡匿外殼30的栓槽⑽來防止推動轴環142與驅動窺線 14 200824639 50的相對旋II。當驅動棘爪丨56脫離推产 ,驅動餅50,推動軸環142會被 纟42時,旋 彈簀⑽的阻力㈣迫㈣釘及刀 =2,從而克服 體32推動驅動器54。 、、且織的方式向砧 5
