[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0015] See also Figure 1 , Figure 2 The utility model provides a technical solution for a head fixing device that is easy to adjust: its structure includes a fixing seat 1 and a U-shaped head positioning member 2. A slide groove 3 is provided in the middle of the top surface of the fixing seat 1. The bottom of the U-shaped head positioning member 2 is slidably arranged in the slide groove 3. A U-shaped assembly groove 4 is provided on the inner side of the U-shaped head positioning member 2. A clamping air cushion 5 is provided in the U-shaped assembly groove 4. An air pump interface 6 is provided on the rear end surface of the fixing seat 1. An air pipe 7 is connected to the input end of the air pump interface 6. The air pipe 7 is connected to the inflation end of the clamping air cushion 5. A driving cavity 8 is provided inside the fixing seat 1. The U-shaped head A tooth plate 9 is provided on the bottom surface of the positioning member 2, and a gear 10 meshing with the tooth plate 9 is provided in the driving cavity 8.
