Abstract

This invention provides a device motion control mechanism, relating to the field of device control technology. The device motion control mechanism includes a handle, a sleeve arm, a working head, a swing-up/swing cable, a transmission cable, and an actuator. The working head is hinged to the front end of the sleeve arm, and the handle is connected to the rear end of the sleeve arm, with the handle being driven by the swing-up/swing cable to the working head. The actuator is mounted on the handle and is also driven by the transmission cable to the working head. In use, wrist movements drive the handle, which in turn drives the swing-up/swing cable to propel the working head in a pitching motion, making operation more convenient. Furthermore, the actuator can drive the working head to perform corresponding actions via the transmission cable. The independent operation of the swing-up/swing cable and the transmission cable ensures that the pitching of the working head and the execution actions do not interfere with each other, improving the reliability of device control.
