Shoulder belt massagers for shoulder and neck massage came into being. Shoulder belt massagers are mainly used to massage the user's shoulder and neck. When in use, the driving device provides mechanical kinetic energy to the massage mechanism, so that the massage mechanism can regularly rotate, swing, vibrate, tap, etc. to relax the user's muscles, improve the blood circulation of the shoulder and neck, and relieve the stiffness and pain of the shoulder and neck muscles.
