A low-power-consumption actuator for battery-powered electronic lock includes assembled first and second cases, the second case being provided at a top with a through bore; a piezoceramic/steel sheet assembly consisting of superposed first and second piezoceramic/steel sheet sets, a first end portion of the second piezoceramic/steel sheet set being in a free state; a circuit board electrically connected to the piezoceramic/steel sheet assembly; and a pin unit being located between a top of the first end portion of the second piezoceramic/steel sheet set and the through bore. When the circuit board applies a voltage across the piezoceramic/steel sheet assembly, the first end portion of the second piezoceramic/steel sheet set upward flexes and thereby displaces to push against the pin unit for a pin thereof to protrude from the through bore and interfere with a latch bolt of the electronic lock, so as to actuate the latch bolt. |
