A device for converting a reciprocating linear motion into a unidirectional circular motion, comprising a main device body (11), and a reciprocating linear motion mechanism (12), a linear motion conversion mechanism (13) and a circular motion output mechanism (14), disposed on the main device body (11). The reciprocating linear motion mechanism (12) is in transmission connection with the linear motion conversion mechanism (13). The linear motion conversion mechanism (13) converts a reciprocating linear motion output by the reciprocating linear motion mechanism (12) into a bidirectional circular motion. The linear motion conversion mechanism (13) is also in unidirectional synchronous rotation connection with the circular motion output mechanism (14). The device converts a manually-driven linear motion mode into a unidirectional circular motion mode, the structure is simple and compact, the aims of changing an output torque and a rotation speed can be achieved by transverse sliding engagement of gear sets, the speed is convenient to regulate, the gear sets in a main device body are randomly arranged according to actual requirements, and the combination quantity of the gear sets can be increased or decreased according to actual requirements. Gears in the gear sets can be arranged in a sequence of large gears, middle gears and small gears, and the speed can be changed step by step. The gears in the gear sets can also be arranged in a sequence of the small gears, the large gears and the middle gears, and the speed is changed in a saltatory manner. |
