Abstract
An operation mechanism for a parasol, including a deflection mechanism, a winding mechanism, a damper mechanism and a clutch mechanism. The deflection mechanism is installed on a locating seat. An upper and a lower sections of the locating seat are formed with upper and lower pin holes. Two shaft rods at two ends of a spiral rod are passed through the upper pin holes with the spiral rod received in the locating seat. One side of the locating seat is rotatably fixed with a first gear. A bottom of a swinging head is formed with a spiral toothed face engaged with and driven by the spiral rod. The winding mechanism and damper mechanism are passed through the lower pin hole. The clutch mechanism connected with a crank is disposed at one end of the winding mechanism. When rotating the crank, the winding mechanism is driven to wind a cord for stretching open the parasol face. When the crank is pulled outward, a second gear of the clutch mechanism is engaged with the first gear of the deflection mechanism so that the deflection mechanism can be driven to adjust the deflection angle of the parasol. By means of pulling out the crank, the operation of the winding mechanism and deflection mechanism can be switched to stretch open the parasol face or deflect the parasol face.
