Title: HAND CRANK MOTOR
Abstract:
A hand crank motor. A flexible shaft (4) is provided inside a steel pipe (3). Both ends of the flexible shaft (4) are respectively fixedly connected with a short shaft (5) and a long shaft (2). A first bearing (10) is provided on the outer periphery of the short shaft (5). A second bearing (11) is provided on the outer periphery of the long shaft (2). The tail end of the long shaft (2) is fixedly connected with a propeller (1). A water seal (12) is provided on the inner side at the bottom of the steel pipe (3). A sun gear (6) is provided at the tail end of the short shaft (5). A gearbox (7) is sleeved on the top end of the steel pipe (3). The sun gear (6) is matched with and fixed to an output shaft on the inner side in the middle of the gearbox (7). A hand crank (8) is provided on the outer side in the middle of the gearbox (7). A user rotates the hand crank (8), so that the gearbox (7) drives the flexible shaft (4) to rotate relative to the steel pipe (3), and accordingly the propeller (1) is rotated. The hand crank motor can save transmission components, has easy direction control, and is convenient to install.
