Due to the massage structure of most massagers, the distance between them is fixed and cannot be adjusted; therefore, when the user is a person with thick limbs, it is often easy to let the massager directly press on the user's pressure because the massage structure is too tightly clamped. Therefore, the user will feel pain due to the excessive force of the massager; when the user has slender limbs, there will be too many gaps between the user's pre-pressed part and the massage structure, so the massage structure cannot be effective Some people press the place that the user wants to press, resulting in the lack of pressing force or no pressing at all.

Improved products on the market such as the Taiwan Publication No. 585108 massager announced on April 21, 2004 and the Japanese Patent Application No. 2002-153532 announced on May 28 (2002-05-28) in 2004, the above-mentioned method All use the screw method to adjust the distance between the massage structure and the user's part, and then achieve the control of the massage force; and here is the No. 585108 massager as an example, and please refer to Figure 1 and Figure 2 ;
