6 results about "Cut fingers" patented technology

A cutting device and a method are designed to facilitate precise cutting and prevent a user from cutting fingers and hands. The cutting device includes a body and a lid. The body has a mounting mechanism, to which a razor blade is removably attached. The lid is pivotably coupled to the body by a spring. Moreover, the lid partially covers the razor blade so that at least one cutting edge of the razor blade is exposed. Thus, the cutting device safeguards the razor blade and protects the user's fingers, hands, and other body parts while allowing at least one cutting edge of the razor blade for cutting operations.

This utility model relates to the field of finger processing technology, and in particular to a positioning fixture for cutting fingers, aiming to solve the problem of unreliable positioning when cutting finger blanks. The positioning fixture for cutting fingers provided by this utility model includes a base and a pressure plate, which are detachably connected. The blank is abutted against the base and pressure plate at both ends along its own axis, and the blank is inserted into the base. The positioning fixture for cutting fingers provided by this utility model achieves locking and positioning of the blank by clamping it from both ends and inserting it into the base, avoiding inaccurate positioning due to side clamping and insufficient clamping force, thus improving positioning reliability and ensuring cutting accuracy.

The utility model discloses a nail clipper with a positioning locking piece. The nail clipper comprises an upper clipper body and a lower clipper body, wherein the tail parts of the upper clipper body and the lower clipper body are connected; the heads of the upper clamp body and the lower clamp body are provided with clamp mouths which are meshed with each other; the clamp cover is connected with the upper clamp body and the lower clamp body through hook nails, the clamp cover is located above the upper clamp body, the clamp cover is provided with a first fulcrum part, and the first fulcrum part is used for applying pressure to the upper clamp body so that the upper clamp body can move towards the lower clamp body; the positioning lock piece is positioned at the tail end of the lower clamp body; the side, facing the upper clamp body, of the positioning lock piece is provided with a lock opening. The inner top face of the locking opening is used for limiting the tail end of the plier cover, so that the plier cover keeps a pressing state on the upper plier body, the plier mouth is further kept in a state that the opening range is reduced or the opening range is closed, the cutting edge is effectively prevented from being exposed to cut fingers and damage other objects, and a user can conveniently carry the plier.

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.
