The top of contiguous block is the concave spherical surface that is complementary with Universal-head, the cancave cambered surface that the bottom is complementary for the periphery with eccentric shaft.This contiguous block contacts with Universal-head, eccentric shaft respectively and is complementary, more effectively fixing Universal-head.
The top end face of the outer surface of Universal-head bottom, contiguous block is matsurface.Matsurface can increase the frictional force between the contact surface.
The outer end of Universal-head is fixedly connected with fixing head, and this fixing head is provided with the through hole of the Kirschner wire that is used to peg graft, and the through hole side is provided with the lock screw that is used for fixing Kirschner wire.
The inner of upper bracket, lower carriage is threaded in the two ends of double-threaded screw respectively, and the side of upper bracket, lower carriage and double-threaded screw junction is equipped with the lock screw of inner roof pressure on double-threaded screw.The two ends screw thread of double-threaded screw is a reverse thread, and side is provided with lock screw, the lock screw more fixedly rotation of double-threaded screw.
Lock screw is hexagon socket head cap screw.Adopt hexagon socket head cap screw to be absorbed in the support.
The intermediary outer surface of double-threaded screw is a regular hexagon.Easier rotation also can be rotated with spanner.
The effect that this utility model is useful is: this utility model compact conformation, overall shape are cylinder, connect simply, rotate flexibly, can all angles rotate, and rotating range is big, and adopt eccentric shaft to fix, and be simple to operate, good fixing effect; Adopt double-threaded screw in the middle of this structure, rotary extension is convenient, and flexible scope is big, can not move after fixing.
