This design solves the problem of angle fixation in traditional double-headed fascia guns, meets the massage needs of users for different parts and angles, and improves the flexibility and applicability of massage. When adjusting the angle of the massage head assembly, open the top cover to disengage the locking and fixing structure 7 from the massage head assembly. Use the arc-shaped limiting structure to move the massage head assembly along the arc trajectory to adjust the angle. When the massage head assembly moves to a position that matches the elastic positioning structure 6, the elastic positioning structure 6 can be used to position the massage head assembly, ensuring that the locking and fixing structure 7 on the top cover can accurately fix the massage head assembly when the top cover is installed.

[0022] Specifically, the massage head assembly 2 includes an adjusting arm 8, a massage arm 9, and a spherical massage head 10. The spherical massage head 10 is fixed to the outer end of the massage arm 9. A vibration motor 11 is installed inside the adjusting arm 8, and the output shaft of the vibration motor 11 is connected to the inner end of the massage arm 9. The massage head assembly adopts a combination design of the adjusting arm, the massage arm, and the spherical massage head. The vibration motor drives the massage arm and the spherical massage head to vibrate through the output shaft. The spherical massage head can better conform to the curves of different parts of the human body. The vibration motor directly drives and improves the vibration transmission efficiency. This structure solves the problem of poor conformity of traditional massage heads, enhances the massage effect, and the modular design facilitates maintenance and replacement.

[0023] Specifically, the arc-shaped limiting structure 5 includes an arc-shaped limiting block 12 protruding from the inner walls of the upper and lower sides of the arc-shaped adjusting slide 3, with the same curvature as the arc-shaped adjusting slide 3.
