A reciprocating saw comprises a housing, a blade assembly, a reciprocating rod assembly, a driving assembly and an operation mechanism. The blade assembly extends forward from one side of the housing, and comprises a positioning structure. The reciprocating rod assembly is detachably connected with the blade assembly and comprises a blade fixing structure and an unlocking component matched with the positioning structures. The driving assembly is accommodated in the housing, and drives the reciprocating rod assembly to drive the blade assembly to perform reciprocating motion. The operation mechanism is installed on the housing and moves between a locking position and an unlocking position and comprises an operation button, a drive cam matched with the unlocking components and an elastic reset component for resetting the operation button.

A percussive massage device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor, a massage attachment configured to be removably attached to the push rod, and an attachment module operatively connected to the housing. The housing includes first, second, and third handle portions that cooperate to define a handle opening, wherein the first handle portion defines a first axis, the second handle portion defines a second axis and the third handle portion defines a third axis, and wherein the first, second, and third axes cooperate to form a triangle.
