Abstract
A remote trigger apparatus includes: an actuator; and a pivoting member rotatable around an axis, wherein the actuator enables the pivoting member to rotate from an idle position to an operating position, in the idle position, the pivoting member keeps separate from a centrifugal mechanism of the governor component, in the operating position, the pivoting member is jointed to a contact part of the centrifugal mechanism of the governor component, and the pivoting member further rotates along with the centrifugal mechanism and radially pushes the contact part inward, so as to trigger the governor component. In the remote trigger apparatus according to an embodiment of the present invention, the pivoting member guides the centrifugal mechanism gradually and gently, thus avoiding direct impacts on the centrifugal mechanism of the governor component and problems caused by the direct impacts.
