It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0018] In conjunction with the accompanying drawings, a head fixation device for neurosurgery includes a base 1, characterized in that a support frame 101 is fixedly arranged on the top of the base 1, a connecting block 2 is arranged on the top of the support frame 101, and an arc plate 3 is symmetrically hinged on the bottom of the connecting block 2, and the outer circle of each arc plate 3 is hinged to the side of the connecting block 2 through an adjustment component 4.

[0019] The adjustment assembly 4 includes a first connecting rod 401, a second connecting rod 402, and a threaded sleeve 403. The first connecting rod 401 is hollow and coaxial with the second connecting rod 402. The outer ring of the second connecting rod 402 abuts against the inner wall of the first connecting rod 401. The first connecting rod 401 is hinged to the side of the connecting block 2, and the second connecting rod 402 is hinged to the outer ring of the arc plate 3.
