An elastic piece wraps around the middle main shell, further reinforcing the connection between the elastic arm and the driving handle. A silicone sleeve is fitted over the tail hood, providing vibration and noise reduction, resulting in a more comfortable user experience. The invention also includes optional features such as a second boss on the elastic arm, a guide boss and groove for precise alignment, and a locking mechanism to prevent accidental detachment. These features enhance the overall stability and functionality of the toothbrush head.
