[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a massage head massager with a mechanical clutch separation mechanism, comprising a housing 17, a motor 3, and a clutch. The clutch includes an adapter 4, a stainless steel spring 5, and a clutch housing 6. The motor 3 is installed inside the housing 17, and the shaft of the motor 3 extends to the outside and is fixedly connected to the adapter 4. The clutch housing 6 has a mounting hole in the middle, and the clutch housing 6 is fitted onto the outside of the adapter 4 through the mounting hole. The stainless steel spring 5 is fitted onto the adapter 4, with one end of the stainless steel spring 5 abutting against the clutch housing 6 and the other end abutting against the adapter 4. The massage head 11 is fitted onto the clutch housing 6 and makes frictional contact with the clutch housing 6. A massage head mesh cover 12 is installed on the outside of the massage head 11. An electronic control component for controlling the motor 3 is installed at the end of the housing 17 away from the motor 3.
[0019] In this embodiment, an inner ring 18 is formed by the protrusion inside the clutch housing 6, and a ring-shaped boss is formed on the adapter 4. The inner ring 18 is sleeved on the outside of the boss. The adapter 4 is provided with a screw hole. An adjusting bolt 10 connected to the screw hole is provided at the center of the clutch housing 6, and a bolt washer 9 is provided between the adjusting bolt 10 and the adapter 4. The clutch housing 6 is locked and fixed to the adapter 4 by the adjusting bolt 10.
[0020] In this embodiment, the clutch housing 6 has an annular groove located inside the inner ring 18 in the middle. A rubber ring 7 is provided in the annular groove, and a stainless steel clutch plate 8 is provided on the surface of the rubber ring 7. The upper surface of the stainless steel clutch plate 8 is in contact with the bolt washer 9. The rubber ring is a wear-resistant O-ring, which can increase the service life.
[0021] In this embodiment, the housing 17 is composed of a rear housing 1 and a front housing 2 of the massager. The rear housing 1 and the front housing 2 of the massager are assembled together, and a motor mounting cavity and an electronic control mounting cavity are formed inside. The motor 3 is installed in the motor mounting cavity, and the electronic control components are installed in the electronic control mounting cavity. A power line 16 for supplying power to the motor 3 and the electronic control components is installed at the end of the housing 17 away from the motor 3.

When the massage head is subjected to a force exceeding the design setting, the clutch will be automatically triggered. The massage head will press down on the clutch housing, causing it to descend and separating the rubber ring from the stainless steel clutch disc. When the clutch is engaged, only the motor drives the adapter and clutch disc to continue rotating, while the clutch housing and massage head do not rotate. When the massage head is reduced to the designed range, the clutch automatically disengages. The rebound of the stainless steel spring allows the rubber ring to contact the stainless steel clutch plate again. Through friction, the stainless steel clutch plate drives the clutch housing to rotate. At this time, the massage head rotates with the motor and motor adapter, continuing to rotate and massage normally. Furthermore, electronic control components are retained as an auxiliary component, forming a "mechanical-electronic dual-mode protection" system that balances accuracy and fault tolerance, greatly improving user experience, product lifespan, and reliability.
