Paw driven guide device with doubled stroke

The invention relates to a paw driven guide device with doubled stroke, which comprises a motor, a fixed base, a ram and a paw, wherein the motor is mounted on the fixed base, and a guide sliding block and a belt fixing seat are mounted on the bottom end surface of the fixed base; a slide rail is mounted above the ram, and the ram is matched with the guide sliding block via the slide rail and can move along the fixed seat; a rack matched with a driving gear is arranged on one side of the ram, and a belt rotating shaft, a belt pulley and an annular belt are mounted on the other side of the ram; a pressing fixed section is arranged on the upper half circle of the annular belt, and is fixed on the belt fixing seat via a belt pressing plate; the paw is fixed on the lower half circle of the annular belt. The paw driven guide device is reasonable in structure and convenient to operate and use; when the ram is driven to perform linear motion, the paw is enabled to perform doubled stroke linear motion; the operation is reliable, and only one power source is required for driving two moving units with different strokes; the paw driven guide device is suitable for installation and driving of a mechanical hand in the industrial production line.
