车床上的外圆车刀有着各种各样的硬质合金与热钢玉用机械方法夹持的结构形式。我们研究并且採用了一种用机械夹持刀头的刀柄结构(如图)。籍助于特殊的楔,可以很容易地调節刀头到需要的高度。这种结构在实际应用上是制造容易,使用简便。如图所示刀具机件的拆开与装合表明并不复杂。这种夹持的方式也可应用于高速钢刀片的夹持。刀柄可以 Lathe lathe tool has a wide range of carbide and hot steel jade with mechanical clamping structure. We have studied and adopted a tool holder that holds the tool bit mechanically (as shown). Thanks to the special wedge, the blade can be easily adjusted to the desired height. This structure in practical applications is easy to manufacture, easy to use. As shown in the disassembly and assembly of the cutting tool shows that is not complicated. This clamping method can also be applied to high-speed steel blade clamping. Shank can be
