[0002] A fascia gun, also known as a deep myofascial release device, is a soft tissue rehabilitation tool that relaxes the body's soft tissues through high-frequency impacts. A fascia gun can be understood as a civilian version of an electric deep muscle stimulator (DMS), with a slightly different vibration frequency during use, but its basic function is similar to a DMS.

[0003] A fascia gun uses a specially designed high-speed motor inside to drive the "gun head," or massage head, to generate high-frequency vibrations that penetrate deep into the muscles, thereby reducing local tissue tension, relieving pain, and promoting blood circulation.

[0004] However, existing fascia guns only have elastic impact, i.e., massage function, lack more functional structures and cannot be adapted to more massage balls with different functions, thus failing to meet more consumer needs. Utility Model Content

[0082] According to the fascia gun of this application, the assembly method of the reciprocating piston and the heating ball head is as follows:
