1. A reciprocating saw, comprising:
an outer housing;
a functional assembly accommodated within the outer housing, the functional assembly comprising:
a motor supported by the outer housing with the motor spaced from an inside surface of the outer housing;
a sliding rod operably coupled to the motor and configured to connect to and drive a saw blade extending from the outer housing; and
a transmission mechanism connecting the motor and the sliding rod, the transmission configured to drive the sliding rod to reciprocate; and
a connecting device rotatably coupling the functional assembly to the outer housing, such that the functional assembly is rotatable relative to the outer housing about the connecting device allowing for an orbital movement of the saw blade,
a buffer coupled between the functional assembly and the outer housing,
wherein the functional assembly is rotatable relative to the outer housing about a first straight line and the first straight line is perpendicular to a cutting plane of the reciprocating saw.
