The positioning hole 3 comprises a shaft positioning hole 31 and an arm positioning hole 32, the shaft positioning hole 31 comprises an outer side wall shaft positioning hole 312 and an inner side arm shaft positioning hole 311, and the arm positioning hole 32 is oppositely arranged on the inner fixing arm and the outer fixing arm 12. The shaft positioning holes 31 can determine the cutting position, so that the purpose of cutting and positioning is achieved, the two shaft positioning holes 31 of the inner arm shaft positioning hole 311 and the outer arm shaft positioning hole 31 can meet the requirements of bone cutting at different positions, and the inner arm shaft positioning hole 311 can be used when the outer arm shaft positioning hole 31 cannot be fixed on a bone.

The outer arm shaft positioning hole 31 is formed at the connection position of the short-distance outer arm 121 and the long-distance outer arm 122. The fixture is arranged at the joint of the short-distance outer side arm 121 and the long-distance outer side arm 122, so that the whole fixture can be effectively adjusted in angle, and the fixture can be fixed on a bone. The inner arm shaft positioning hole 311 is formed at the connection between the short-distance inner arm 111 and the long-distance outer arm 122. The installation at the junction of the short-distance inner side arm 111 and the long-distance inner side arm 112 can effectively enable the whole body to be adjustable in angle, and the fixture can be fixed on the foot skeleton. In general, only one of the outer arm shaft positioning hole 31 and the inner arm shaft positioning hole 311 needs to be fixed, so that the shaft positioning hole 31 can be disposed.
