An electric pruner includes a housing, a motor accommodated within the housing, a transmission mechanism, a movable blade, and a fixed blade extending from the front end of the housing. The fixed blade is fixedly mounted on the housing, and the movable blade is rotatably connected to the fixed blade via a shaft and driven by the motor via the transmission mechanism. A groove is formed on the movable blade and comprises a first and a second groove portion, the size of the first portion being greater than that of the second portion. The shaft comprises a first mating portion and a second mating portion, and is movable between a first position and a second releasing the movable blade when the shaft is in the second position. Thus, the replacement of the movable blade is very simple and convenient.
