[0002] Massage equipment is mainly used for massaging human muscles to relax muscles and relieve fatigue. One type of massager is mainly aimed at massaging the neck and shoulders. The massage methods mainly include hammering massage and kneading massage. The traditional hammering massage method generally only sets eccentric wheels to cooperate with hammering arms to drive the hammering arms to swing and thus realize hammering massage. However, this hammering method can only hammer massage at a single position, and the range of hammering massage is very limited. If the hammering position needs to be changed, the position of the machine core needs to be adjusted. Some massage machine cores are even difficult to adjust the position, resulting in a narrow user group, poor comfort and unobvious humanized design experience. In addition, how to realize stable transmission inside the machine core, improve the stability and sensitivity of the hammering arm action, and reduce the load of the internal action mechanism are some problems to be solved at present.
