description	The invention relates to the technical field of vein recognition, discloses a vein ring for safety verification, which can be normally used in a cold environment. The vein ring comprises a ring body,a pressing plate is movably connected to the top of a top seat, a limiting rod is movably inserted into the bottom of the pressing plate, an inserting rod is fixedly connected to the bottom of the pressing plate, a connecting rod is movably connected between the limiting rod and the inserting rod, a magnetic sleeve is movably connected to the side, away from the limiting rod, of the inserting rodthrough a lever, a guide rod is arranged in the top seat, and a heating piece is fixedly connected in the ring body. When identity authentication is performed, the pressing plate is pressed, the limiting rod is separated from the rotating ring; then the rotating ring is rotated, the first contact piece makes contact with the second contact piece, a circuit is connected, and verification is started.
