Abstract: The present invention provides a clutch gear device, which has a structure comprising a driving gear, an external forward-reverse rotation clutch and an internal forward-reverse rotation clutch. Two sides of the driving gear are provided with a left forward-reverse rotation gear shifting member and a right forward-reverse rotation gear shifting member that are arranged in different directions and in an array. The shifting member has a structure of an inclined surface and a vertical surface. The external forward-reverse rotation clutch is installed on the gear shaft at the external side of the driving gear. The internal side of the external forward-reverse rotation clutch has an external forward-reverse rotation gear shifting member corresponding to the left forward-reverse rotation gear shifting member of the driving gear. A positioning block is installed on the gear shaft at the external side of the external forward-reverse rotation clutch. An elastic member is installed between the external forward-reverse rotation clutch and the positioning block. The internal forward-reverse rotation clutch is installed on the axial center at the internal side of the driving gear. The external side of the internal forward-reverse rotation clutch is provided with an internal forward-reverse rotation gear shifting member corresponding to the right forward-reverse rotation gear shifting member of the driving gear. A positioning block is installed on the gear shaft at the external side of the internal forward-reverse rotation clutch. An elastic member is installed between the positioning block and the internal forward-reverse rotation clutch. In a quiescent state, the internal and the external forward-reverse rotation clutches are pushed by the elastic member to move toward the central driving gear. The left and the right forward-reverse rotation gear shifting members are respectively engaged with the internal and the external forward-reverse rotation gear shifting members at two sides. When the driving gear rotates forwards, the left forward-reverse rotation gear shifting member of the driving gear and the external forward-reverse rotation gear shifting member of the external forward-reverse rotation clutch are mutually engaged due to a mutual contact with the vertical surface and a push of the elastic member. The right forward-reverse rotation gear shifting member of the driving gear and the internal forward-reverse rotation gear shifting member of the internal forward-reverse rotation clutch are in an inclined contact state, so that the internal forward-reverse rotation clutch will be pushed toward the outside so as not to be engaged with the driving gear. When the driving gear rotates backwards, the right forward-reverse rotation gear shifting member of the driving gear and the internal forward-reverse rotation gear shifting member of the internal forward-reverse rotation clutch are mutually engaged due to a mutual contact with the vertical surface and a push of the elastic member. At this time, the left forward-reverse rotation gear shifting member of the driving gear and the external forward-reverse rotation gear shifting member of the external forward-reverse rotation clutch are in an inclined contact state, so that the external forward-reverse rotation clutch are pushed outwards. Therefore, when rotating forwards or reversely, the driving gear performs an engaging action with one of the external forward-reverse rotation clutch and the internal forward-reverse clutch to cause an alternative cycle and, in performing an action, the one without engagement will not interfere the device.
