The specific embodiment

For further setting forth this utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to according to the vertebra fixer structure that the utility model proposes, its specific embodiment, structure, feature and effect thereof, describe in detail as after.

See also Fig. 2, Fig. 3 and shown in Figure 4, this utility model vertebra fixer structure, it mainly comprises: holder 20 is the fixed bars for an elongated, its length and external diameter equidimension do not limit, can be according to actual needs suitable increase and decrease length and external diameter.As shown in Figure 6, promptly disclose the holder 20 that has a length long.

This holder 20 includes one first body of rod 21 and one second body of rod 22, and wherein this first body of rod 21 is a circular body of rod, and the one end is formed with a pommel 211, and this pommel 211 is to be spherical shape, and the external diameter in this pommel 211 is the external diameters greater than this first body of rod 21.

This second body of rod 22 also is a circular body of rod, the one end is to be formed with a junction 221, this connecting portion 221 is to be shaped in this second body of rod, 22 1 ends, the external diameter of this connecting portion 221 is greater than these second body of rod, 22 external diameters, and these connecting portion 221 inside be offer one with pommel 211 corresponding ball-joint nests 222, these ball-joint nest 222 inwalls are to be concave arc shape, can be in order to cooperate with pommel 211.

The pommel 211 of this first body of rod 21 is to be matched with in the ball-joint nest 222 of this second body of rod 22, and this pommel 211 can rotate rotation freely in this ball-joint nest 222, makes it form a universal joints structure; By above-mentioned composition to form vertebra fixer structure of the present utility model.
