Description

Technical Field

[0001] The utility model relates to the field of fascia guns, in particular to a fascia gun with variable amplitude. Background Art

[0002] Exercise is crucial for a person's physical and mental health, but its implementation must adhere to scientific principles to avoid injuries caused by improper exercise techniques. Muscle strains are one of the most common problems in all types of sports. While traditional strategies such as warm-up and stretching can help relax muscles, their effectiveness is often limited during high-intensity or strenuous exercise. Consequently, athletes, rehabilitation professionals, and fitness enthusiasts are seeking more effective muscle relaxation methods, with the increasing use of fascia guns. By generating high-frequency impact force, fascia guns can deeply penetrate muscle tissue and the myofascia, exerting significant restorative and soothing effects. Specifically, they effectively relieve muscle spasms, break down tissue adhesions, inhibit hyperactivity, and accelerate the breakdown and metabolism of inflammatory products, thereby optimizing the internal tissue environment. This deep and precise muscle relaxation helps prevent and alleviate delayed onset muscle soreness, allowing athletes to better enjoy the benefits of exercise while reducing the risk of injury.

[0003] Massage guns currently on the market typically feature multiple operating modes to accommodate diverse user needs. However, the core difference between these modes lies solely in the speed of the massage vibrations, achieved by adjusting the drive motor's gears. However, the vibration intensity (i.e., amplitude) of existing massage guns is often fixed and cannot be flexibly adjusted to suit individual user preferences. Therefore, it is difficult to fully meet the personalized needs of different individuals for deep muscle and fascia massage. Therefore, a variable-amplitude massage gun that addresses this issue is needed. Utility Model Content
