Abstract

A reciprocating saw includes a casing, a power assembly, a transmission assembly, a reciprocating assembly, a swing assembly, and a balance weight. The transmission assembly includes a first transmission member that is capable of being driven by the power assembly to rotate around a first axis. The swing assembly includes a floating support member configured to drive the reciprocating assembly to perform an orbital motion. The first transmission member is provided with a cam surface configured to be in contact with the floating support member to drive the floating support member to move in an up-and-down direction parallel to the first axis. The balance weight is provided with an escape opening, and the escape opening is disposed on a path on which the floating support member moves in the up-and-down direction.
