Description

Technical Field

[0001] The utility model relates to the technical field of motor components, in particular to a motor component for a fascia gun. Background Technique

[0002] A fascia gun, also known as a muscle fascia relaxation massage gun, has the following main functions: First, through high-frequency vibration stimulation, the fascia gun reduces the adhesion and nodules between muscles and fascia, alleviates muscle stiffness and soreness, and increases blood circulation and range of motion; Second, for those who lack physical exercise for a long time and are prone to injuries in the shoulders, necks, waists, etc., the fascia gun has a good effect on lumbar muscle strain and foot massage, thus preventing back, shoulder and neck pain. In addition, the fascia gun also has functions such as fat burning and eliminating muscle legs, and is currently increasingly favored by health-conscious people, especially sports enthusiasts.

[0003] The invention application document with the publication number of "CN116196210A" discloses a dual-purpose fascia gun, which mainly consists of a fascia gun body, a reciprocating component, a rotating component, an upper motor shaft and a lower motor shaft. This technical solution has the advantage of shock absorption effect, and solves the problem that when different functions need to be realized, by adjusting the driving motor, the upper motor shaft or the lower motor shaft on the driving motor is used for driving. The two functions are driven separately, which can avoid repeated operation and excessive consumption of the driving motor.

[0004] The above-mentioned dual-purpose fascia gun disclosed in the document has the following defects: During the use of this dual-purpose fascia gun, since different parts need to be massaged, massage heads with different shapes, sizes and hardnesses need to be replaced.
