The present invention provides an actuator, a remote triggering apparatus, a governor, and an elevator. The actuator includes: a mandrel, the mandrel having a proximal end and a distal end, and the mandrel being driven to move from a contraction position toward an actuation position; a mandrel sleeve, the mandrel sleeve being sleeved on the distal end of the mandrel; and a shell, the shell defining a channel, wherein the actuator further includes at least one sliding member, and when the mandrel moves from the contraction position toward the actuation position, the at least one sliding member is located at a first radial position where the mandrel is joined to the mandrel sleeve, such that the mandrel sleeve can move along the channel together with the mandrel; and wherein at the actuation position, the at least one sliding member moves outward radially to a second radial position where the mandrel sleeve is joined to the shell, thus locking the mandrel sleeve.
