Description

A mechanical mouse hand massager

technical field

The invention relates to a massager, in particular to a mechanical mouse hand massager.

Background technique

Massage therapy is favored by the majority of people because of its painless and side effects. At present, more and more people use the mouse for a long time to cause pain and stiffness in the wrist, which brings great harm to physical and mental health. The instrument has a very high health care value.

The current massage methods are mainly divided into two categories, namely, manual massager and hand-held vibration massager.

Among them, the artificial massagers are mostly made of soft polymer materials. When using, manually grasp and loosen the artificial massager to relieve the symptoms of the mouse hand through the movement of the fingers. The treatment of patients with wrist pain is very difficult, and the massage effect on the wrist is not obvious.

The hand-held vibrating massager achieves the massage effect through the vibration impact of the massage hammer, which needs to be held by hand, while the soft tissue at the wrist is less, and the impact force of the massage hammer is large, which causes pain in the hand bones, and the vibration massager itself is large in size and weight. People who hold the vibrating massager will get tired quickly, so the massage treatment effect of the vibrating massager on the mouse hand is not ideal.
