One end of the second connecting rod 19 is fixedly connected to the connecting seat 9, and the other end of the second connecting rod 19 is clamped with the through hole 21.

[0051] Specifically, in order to better adjust the position of the fixator, a second connecting assembly can be installed additionally, which is a second connecting rod 19 composed of a plurality of rod bodies nested in sequence, and adjacent rod bodies can move along the axial direction of the second connecting rod 19. In this way, the doctor can control the length of the second connecting rod 19 by pulling the rod body, and can control the height of the second connecting rod 19 by inserting one end of the second connecting rod 19 into one of the through holes 21 of the third connecting rod 20, so that the fixator can be adjusted at will in the horizontal and vertical directions, thereby improving the applicability of the fixator, and the other end of the second connecting rod 19 can be fixed to the connecting seat 9 by welding or bonding to improve stability.

[0052] In the above embodiment, further, a plurality of through holes 21 are evenly spaced on the outer wall of the third connecting rod 20 along the axis direction of the third connecting rod 20.
