Detailed Description
The invention will be further elucidated with reference to the accompanying drawings:
adjustable foldable position fixing device of artifical hip joint replacement art, its characterized in that: the folding adjusting device comprises an isosceles trapezoid top plate 1, a right-angle trapezoid side plate I2, a right-angle trapezoid side plate II 4 and an adjusting folding supporting rod 3;
the right-angle trapezoid side plate I2 and the right-angle trapezoid side plate II 4 are identical in structure, one waist of the isosceles trapezoid top plate 1 and the right-angle waist of the right-angle trapezoid side plate I2 are fixed in a hinged mode, the other waist of the isosceles trapezoid top plate 1 and the right-angle waist of the right-angle trapezoid side plate II 4 are fixed in a hinged mode, and the specific hinged mode is that the waist and the right-angle waist are connected through hinges; the lower part of the isosceles trapezoid top plate 1 is provided with a row of threaded holes with a positioning function;
one end of the folding adjusting supporting rod 3 is connected with the inner side of the isosceles trapezoid top plate 1 through a pin shaft, the folding adjusting supporting rod 3 can integrally rotate around the pin shaft, the other end of the folding adjusting supporting rod 3 is connected with threaded holes formed in the isosceles trapezoid top plate 1 through bolts, the number of the threaded holes is preferably 8, the threaded holes in the central position are 90-degree positioning holes, when the two folding adjusting supporting rods 3 are connected with the 90-degree positioning holes, the right trapezoid side plate I2 and the right trapezoid side plate II 4 are perpendicular to the isosceles trapezoid top plate 1, and at the moment, the included angle between the right trapezoid side plate I2 and the right trapezoid side plate II 4 is 30 degrees; the threaded holes on two sides of the threaded hole in the central position are a 105-degree positioning hole, a 110-degree positioning hole, a 115-degree positioning hole and a 120-degree positioning hole in sequence, and similarly, when the positioning holes on two sides of the threaded hole in the central position are respectively connected with the adjusting folding supporting rods 3 on one side of each threaded hole, the right-angled trapezoid side plate I2 or the right-angled trapezoid side plate II 4 forms 105 degrees, 110 degrees, 115 degrees and 120 degrees with the isosceles trapezoid top plate 1;
