介绍两种适用车床的小结构１．手轮自动解脱机构在车床上，当溜板纵向快速移动（或机动进给）及刀架横向快速移动（或机动进给）时，其手轮随之旋转，很不安全。目前虽有手动解脱式安全手柄，但操作者嫌麻烦往往不用，安全手柄失去作用。图１是自动解脱安全手轮的结构示意... Introduce two kinds of small structure for lathe 1. Handwheel automatic release mechanism In the lathe, when the slide longitudinal fast-moving (or motorized feed) and the turret rapid lateral movement (or motor feed), the hand wheel rotation, it is not safe. At present, although the manual release of the safety handle, but operators often find it troublesome, safety handle lost its effect. Figure 1 is a schematic illustration of the structure of a safety hand wheel
