Iris image capturing device

The utility model relates to the technical field of capturing equipment, in particular to iris image capturing equipment, which comprises a machine body, two side surfaces of the machine body are fixedly connected with sliding frames, and the interiors of the two sliding frames are connected with sliding plates in a sliding manner. The utility model has the advantages that the connecting rod is pulled to drive the pawl to be far away from the ratchet wheel, then the collector is rotated until the angle is proper, the connecting rod is loosened to move downwards under the extrusion of the second spring, the collector can be locked through the clamping connection of the ratchet wheel and the pawl, and the angle of the capture lens can be adjusted; after iris image collection is completed, the collector can be rotated until the capturing lens is vertically downward, then the top plate is pressed to move downward until the capturing lens is in contact with the sponge pad, and the sponge pad can be tightly attache
