摘要： A transmission device of an electronic lock, disposed in a lock body, each of both sides of the lock body is provided with a rose assembly, connected respectively to a handle, to drive a driving seat to bring a latch bolt of a latch unit into action. The transmission device is controlled electronically, comprising: a positioning element, a motor, an elastic element, a rod, a clutch element, and a spring. The clutch element is slideable in the spindle, to move between a first position where the clutch element engages with the spindle and a second position where the clutch element disengages from the spindle, such that when the clutch element engages with the spindle, the spindle drives the driving seat, to retract the latch bolt of the latch unit.
