Abstract

The invention provides a propelling system which comprises a power input shaft (1), an input shaft gear (2), a spiral propeller (3), a lock gear (7), a position indication dial, a lock assembly and a support frame. The lock assembly comprises a first fixing plate (6), a second fixing plate (4), lock pins (5), a stop pin and a reset spring. The number of the lock pins (5) is two. The first fixing plate (6) and the second fixing plate (4) are arranged in parallel and are respectively provided with a through hole, wherein the lock pins (5) penetrate through the through holes. A pin hole is exposed between the first fixing plate (6) and the lock gear (7) when the pins (5) extend out and are jointed with a lock hole in the lock gear (7). The pin hole is used for resetting the stop pin in an inserted mode when the lock pins (5) are manually pulled to a retraction position and the pin hole is exposed between the first fixing plate (6) and the second fixing plate (4). After the stop pin is inserted and reset, the lock pins (5) do not make contact with the lock gear (7), and therefore the lock function of the lock gear (7) is lost.

Description
