Abstract

A reciprocating power tool includes a housing; a power assembly including an electric motor; a transmission assembly connected to the power assembly; a reciprocating assembly connected to the transmission assembly, performing a reciprocating motion, and mountable with a working accessory for an operation; and a balancing component for balancing a motion of the reciprocating assembly. A maximum distance the centroid of the reciprocating assembly moves is a first distance L1; a maximum distance the centroid of the balancing component moves is a second distance L2; the mass of the reciprocating assembly is a first mass M1, and the mass of the balancing component is a second mass M2; the ratio of a product M2·L2 of the second mass M2 and the second distance L2 to a product M1·L1 of the first mass M1 and the first distance L1 is greater than 1.05.
