Description

Massage gun including a direction change function {MASSAGE GUN WITH REVERSING FUNCTION}

The present invention relates to a massage gun, and more particularly, to a massage gun capable of changing the direction of a massage head so that each part of the body can be massaged.

People in modern cities are living faster and faster. In a tense life, most people suffer from various stresses. After long-term labor or work, the muscles and nerves of the body get tired easily and should be recovered through appropriate rest, but the body itself takes a very long time to recover. , If an external massage tool is used, the recovery time can be shortened, so there are a lot of massage tools on the market.

However, most of the existing massage devices sold in the market are mid- to large-sized devices such as massage chairs and massagers. If users want to use these devices, they must be used in a specific place, and relatively high demands are required for usage time. Since it causes certain inconvenience to the people, the relatively small volume of the massage stick gradually begins to come into people's field of vision.

Currently, the structural principle of the handheld massager on the market is basically using one small motor to operate the eccentric hammer together, and the inertia generated by the eccentric hammer causes the vibrating body to generate periodic vibrations to achieve the purpose of massaging the human body do. However, existing handheld massage rods have a complicated internal structure, relatively high production cost, and commonly used small massage hammers have defects such as fixed massage head shape, non-replaceable, and relatively large vibration and noise.
