[0033] The top of the base 1 is fixedly connected with a lying bed 2, and the surface of the lying bed 2 is paved with a medical silica gel pad which is soft, comfortable, easy to clean and disinfect. The medical silica gel pad is soft in texture, conforms to the patient's body, can increase comfort when the patient lies down, and its smooth surface facilitates postoperative cleaning and disinfection, meets the hygiene requirements of the operating room, and can avoid the breeding of bacteria caused by stain residues.

[0034] One side of the lying bed 2 is fixedly connected with a shell 3, and the shell 3 is made of high-strength engineering plastic. The shell 3 made of engineering plastic is light in quality, convenient to move and install, and has sufficient strength to protect the internal drive assembly and other components from damage caused by external factors. A sliding groove is formed in the top of the shell 3. The sliding groove in the top of the shell 3 is finely polished and smooth in surface and high in dimensional accuracy. Such a sliding groove can ensure smooth movement of the parts, reduce friction, accurately cooperate with the movement of the drive assembly, and make the parts move along the predetermined trajectory, achieving stable and accurate fixation of the patient's head.
