[0006] Preferably, the top view shapes of the lower fixing plate and the upper fixing plate are both circular.

[0007] Preferably, the size of the upper fixing plate is larger than that of the lower fixing plate.

[0008] Preferably, the inner diameter of the connecting tube is slightly larger than the diameter of the main rod.

[0009] Compared with the prior art, the beneficial effects of the present invention are: the improved skull lock,

[0010] (1) A main rod, a connecting groove, a connecting head and a connecting tube are provided. When the improved skull lock is used, the lower fixing plate can be rotated in the connecting groove to adjust the fixing position and angle through the connecting head, and the upper fixing plate can be fine-tuned left and right on the main rod through the connecting tube, so that the fixing effect is better and the skull is better fixed;

[0011] (2) A main rod, a second connecting hole, a first connecting screw and a second connecting screw are provided. When the improved skull lock is used, the lower fixing plate can be fixed by the first connecting screw, and the upper fixing plate can be fixed by the second connecting screw, making the improved skull lock more convenient to use and more effective.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-5 The utility model provides a technical solution: an improved skull lock, a lower fixing plate 3 is provided under the main rod 1, the upper side of the lower fixing plate 3 extends to the inside of the connecting groove 2 and is connected to a connecting head 4, and the front end of the connecting head 4 passes through to the rear end of the connecting head 4 and is provided with a first connecting hole 5, the front end of the main rod 1 is connected to the first connecting hole 5 through a first connecting screw 6, an upper fixing plate 8 is sleeved on the outer side of the main rod 1, and a connecting tube 9 is provided on the upper side of the upper fixing plate 8, and the front side of the connecting tube 9 is connected to the second connecting hole 7 through a second connecting screw 10, the lower fixing plate 3 can be rotated left and right inside the connecting groove 2 through the connecting head 4, so that the lower fixing plate 3 can adjust its angle according to the situation of the lower side of the skull, and the upper fixing plate 8 can adjust its angle according to the situation of the upper side of the skull through the connecting tube 9, which makes the fixation effect of the skull better.

[0020] like Figure 1 and Figure 2 As shown, a connecting groove 2 is provided at the bottom end of the main rod 1, a second connecting hole 7 is provided on the front side of the main rod 1, and the second connecting holes 7 are arranged at equal intervals.
