    Abstract: An adjustable stroke percussion massage device includes a stroke arm having a first end connected to a percussion massage head. A pin extends outward at a second end of the stroke arm. A cam has a cam slot formed into the cam such that the pin fits into the cam slot. The cam slot has a length, where the pin is movable from a first end of the cam slot to a second end of the cam slot, where the pin is a first distance from a rotation axis of the cam when positioned at the first end of the cam slot, and the pin is a second distance from the rotation axis of the cam when positioned at the second end of the cam slot. A motor is operable to rotate the cam about the rotation axis, moving the stroke arm along a vibration axis.

    Abstract: An adjustable stroke length percussion massage device includes a stroke arm connected to a piston which is connected to a massage tool for providing a massage to a user. The stroke arm is secured to a crank pin of a crank mechanism which includes a rotatably connected crank housing and crank base, the crank pin being movably secured between the crank housing and crank base such that the crank pin moves from a first end to a second end of a sliding groove located in the cam housing when a rotation direction of the single unit is reversed by a motor. When the crank pin is moved from the first end to the second end of the sliding groove, a stroke length of the piston is changed.
