Embodiment Construction
[0019] Such as figure 1 As shown, a plastic orthopedic external fixator connecting rod is composed of a fixing rod 3, a tension bolt 2, a double spherical spacer 4 and a cable 1. One side of the double spherical gasket 4 is a convex spherical surface, the other side is a concave spherical surface, the two spherical surfaces are parallel, and the middle of the gasket is a hole; the fixed rod 3 is two separate rods, and each fixed rod 3 is a hole in the middle. The inner hole of each fixed rod 3 end has an internal thread, and the part of one rod in contact with the double spherical gasket 4 is a convex spherical surface, and the part of the other rod in contact with the double spherical gasket 4 is a concave spherical surface; The tension bolt 2 is also a cylinder with a hole in the middle, and its outer diameter is equal to the internal hole at the end of the fixed rod 3. The surface of the tension bolt 2 has external threads, and the external threads and the internal holes at...
