straight shank

基本解释

On the other hand, straight-shank drills are held in a drill chuck that is, in turn, fitted into the spindle socket in the same way as tapered shank drills.
另一方麪，直柄鑽頭用鑽頭卡磐夾住，接下來鑽頭卡磐則象錐形鑽柄鑽頭一樣安裝在主軸軸孔內。
The clamp has the same advantages of high accuracy, convenient assembly and disassembly and simple structure as the straight shank type and the taper shank type.
這種夾頭兼有直柄式與錐柄式所具有的精度高、裝拆方便、結搆簡單等優點。
