摘要： PURPOSE:To prevent vibration caused by a shock, in which a stopper piece hits a positioing limit part at resetting time of a turning cam, by resetting a movable holder through pull down motion of a handle and the turning cam automatically to a cutting start position. CONSTITUTION:A cam part (a), pressure receiving cam part (b) and recessed parts of a brake cam part (c), cut up positioning part (d), escape turn promoting part (e), escape turn deceleration part (f), etc. are formed to a turning cam 9. And successively to the above parts, a turning cam resetting sloped cam part (g) and an escape resetting part (h), which can automatically turn an auxiliary resetting upper subpawl 16 in parallel to the cam part (g), are provided, while a resetting sloped cam part (i) only use for the subpawl 16 is parallel to the recessed parts (e), (f) is formed in a staircase shape from the resetting part (h) partially successively to the cam part (g). In this way, interlocking to the resetting of a movable holder 2 by a resetting depressive handle 6 fixed to the holder 2, the turning cam is automatically reset to a cutting start position and thread cutting work can be repeatedly performed.
摘要翻译：目的：为了防止在通过手柄的下拉运动和转动凸轮自动切换到切割开始位置的情况下通过将可动夹持器复位而使止动片撞击转动凸轮的复位时的止挡件撞击定位极限部分而产生的振动。构成：凸轮部分（a），受压凸轮部分（b）和制动器凸轮部分（c）的凹陷部分，切割定位部分（d），逃生转向部分（e），逃生转弯减速部分）等形成为转动凸轮9.并且依次连接到上述部件，转动凸轮复位倾斜凸轮部分（g）和逃生复位部分（h），其可以并行地自动地转动辅助复位上部副棘爪16 设置在凸轮部分（g）上，而仅用于副爪16的复位倾斜凸轮部分（i）平行于凹部（e），（f）从复位部分形成阶梯形状 h）部分地依次连接到凸轮部分（g）。以这种方式，通过固定到保持器2的复位抑制手柄6与可移动保持器2的复位联动，转动凸轮自动复位到切割开始位置，并且可以重复执行螺纹切削加工。
