    • The tightness-checking apparatus of a milling vice of the present invention has tightness display parts (32) formed intermittently on the outer circumferential surface of a fixed ring (8) at certain intervals for being able to check the tightness between a fixed jaw (2) and a moving jaw (3) due to the rotation of a rotation screw (7); and a reference point display part (34) formed in the centre of the top surface of a support bracket (10) for providing a reference point so that an increase/decrease in the rotation of the rotation screw (7) can be checked using the tightness display part (32), and thereby removes errors resulting from changes in tightening pressure when rotating the rotation screw (7) so that a large quantity of workpieces can be clamped between the fixed jaw (2) and the moving jaw (3), while being capable of maintaining a uniform processing accuracy for a large quantity of workpieces and preventing safety-related accidents due to workpieces escaping.
    • 本发明的铣刀的松紧度检查装置具有以一定的间隔间歇地形成在固定环8的外圆周表面上的紧密度显示部分32,以便能够检查固定环8的紧密度 )和由于旋转螺钉(7)的旋转而移动的钳口(3); 以及参考点显示部分(34),其形成在用于提供参考点的支撑托架(10)的顶面的中心,使得可以使用所述参考点来检查所述旋转螺杆(7)的旋转的增大/减小 从而消除了当旋转螺杆(7)旋转时由于紧固压力的变化而导致的错误,使得大量工件可以夹紧在固定夹爪(2)和移动夹爪(3)之间, 同时能够对大量工件保持统一的加工精度,并且防止工件逃逸引起的安全相关事故。
