[0002] The head-grabbing massager is a common massage tool, mainly composed of a handle, a massage head part and a connecting part. The handle is ergonomically designed and is usually made of soft and easy-to-grip material to provide a comfortable grip. The massage head part includes multiple massage points with various shapes and materials, designed to provide moderate stimulation and massage sensation, promote blood circulation in the head, relieve headaches and tension, promote hair growth, and reduce stress and anxiety. The connecting part ensures that the massager has a firm structure and will not become loose or damaged during use, such as stainless steel ribs. The material selection focuses on safety in contact with the human body. The massage head part is often made of medical-grade plastic, stainless steel, silicone or rubber. Some massage The device has an adjustable design, allowing users to adjust the shape or the position of massage points according to personal needs. However, the current scratching head massagers mainly fix several stainless steel ribs at the bottom of the handle by welding or pressure compression. The stainless steel ribs may loosen or break due to wear at the welding points or pressure points during long-term use, thereby affecting the stability and life of the massager. Especially when the user uses it frequently or with great force, the fixed part is susceptible to greater pressure and friction, resulting in an unstable structure. The welding or pressure-pressing fixing method is also prone to problems such as unstable welding points and uneven pressure during production, thereby affecting the quality and consistency of the massager.

Then the staff makes the inner wiring column 3, the support plate 6 and the docking cavity 2 concentrically and continuously screws the threaded retraction sleeve 5 so that the threaded retraction sleeve 5 and the handle 1 are threadedly matched. Then, under the action of the threaded rotation belt of the handle 1 and the threaded retraction sleeve 5, the inner wiring column 3, the annular lip plate 4, the support plate 6 and other components continue to move upward until the inner wiring column 3 is completely entered into the docking cavity 2. At this time, the massager is initially assembled in place, and the staff takes out a positioning screw 8 , so that the positioning screw 8 is screwed into the inner wiring column 3, the support plate 6 and the internal threaded hole 101 through the countersunk hole 301, and then the countersunk hole 301 is used to completely fix it to the inner wiring column 3, the support plate 6 and the handle 1, and the assembly of the massager is completed. In this process, the welding points of the support plate 6 and the massage claw part 7 are hidden, and the design of the threaded retraction sleeve 5 being installed in the handle 1 ensures that the connection between the support plate 6 and the massage claw part 7 is tight and firm, reducing the loosening and breakage problems that may exist due to conventional welding or pressure fixing methods, thereby improving the overall stability of the massager. At the same time, the design of the inner wiring column 3 and the threaded retraction sleeve 5 is easier to achieve precise process control than the traditional welding or pressure fixing method, reducing the quality fluctuations that may be caused by problems such as uneven welding points and unstable pressure during the production process.
