A hand-held massaging system includes a swivel coupling for removably attaching a massage tool to a reciprocating motor having a shaft having a stroke axis and a stroke length. The swivel coupling consists of a thrust journal and a cylindrical cup, an inner diameter of the cup providing a swivel bearing and bottom of the cup forming a thrust bearing. When the shaft reciprocates at a forced frequency, the thrust journal is retained within the cup by stick-slip friction that allows the thrust journal to swivel within the cup and to slip along the stroke axis. The thrust journal and cup attach between the massage tool and the shaft.

A percussive massage device may include a housing having a housing interior. A motor may be positioned in the housing interior and may include a rotatable motor shaft having a motor axis. A battery may be positioned in the housing interior. A switch may be configured to activate the motor. A reciprocating shaft may operatively be connected to the rotatable motor shaft. The reciprocating shaft may include a distal end and is able to reciprocate in response to rotation of the rotatable motor shaft. A vent may extend through a vent opening in the housing to provide ventilation to the housing interior.

A massager includes a shell component provided with a contact side plate; a semiconductor refrigeration sheet, wherein the semiconductor refrigeration sheet is provided in the shell component, and the first working surface of the semiconductor refrigeration sheet is attached to the contact side plate; at least two electrode plates, wherein all of the electrode plates are provided on the contact side plate, and the polarities of the at least two electrode plates are opposite. The massager and the control method thereof according to the present disclosure use the semiconductor refrigeration sheet to cool or heat, so that the massager can realize various massage functions of cold compress, hot compress and alternating cold and hot massage, and achieve the effect of dissolving fat particles and discharging the fat particles out of the body. Moreover, an electrode plate is provided to release pulses, so that muscles can exercise passively.
