AI Technical Summary
Technical Problem
The lack of a dedicated positioning device or guiding structure in the existing technology leads to a deviation in the symmetry of the two halves of the retaining ring after the finger retaining ring is cut, which affects the fit of subsequent assembly.
Method used
The design adopts a positioning post and a limiting plate interlocking. The finger retaining ring is fastened to the positioning post by the fastening component, and after rotating 180° around its own axis, it is inserted into the limiting plate again. The use of the limiting groove and the fastening component ensures the symmetry of the two retaining rings after cutting.
Benefits of technology
This design ensures the symmetry of the two retaining rings after cutting, improving the fit of subsequent assembly.

Abstract
This utility model relates to the field of cutting finger retaining rings, and in particular to a positioning fixture for cutting finger retaining rings. The positioning fixture includes: a positioning post, a limiting plate, and a fastening assembly; the positioning post is used to fit the finger retaining ring, one end of which is used to insert into the limiting plate, and can be re-inserted into the limiting plate after rotating 180° around its own axis; the limiting plate can restrict the rotation of the positioning post around its own axis when it is inserted into the positioning post; the fastening assembly is detachably connected to the other end of the positioning post, and can fasten the finger retaining ring to the positioning post in the connected state. This positioning fixture for cutting finger retaining rings alleviates the technical problem of symmetry deviation in the two halves of the cut retaining ring in the prior art, ensuring the fit of the upper and lower retaining rings during subsequent assembly.
