Abstract:
1. A safety apparatus for preventing industrial safety problems of a machine tool caused in a work-loading process, comprises: a work-loading device, used for work loading; an actuator, used for connecting circuits of the machine tool to control an ON-OFF status thereof; and a storing unit, used for setting the work-loading device; wherein the storing unit will turn on the actuator if the work-loading device is located at a first site previously designated by the storing unit and, therefore, will have the circuits of the machine tool stay in an ON status; wherein the storing unit will suppress the actuator function if the work-loading device is located in a position other than the first site previously designated by the storing unit and, therefore, will have the circuits of the machine tool stay in a power-OFF status; wherein the storing unit comprises a fixture to lead and secure the work-loading device at the first site; wherein the actuator comprises a click-typed ON-OFF switch; and wherein the click-typed ON-OFF switch is set under the fixture of the storing unit, and is activated by the weight of the work-loading device when the work-loading device is returned to the designated safe position on the storing unit.
