Portable optical glass blank thickness difference detection device

The utility model relates to the technical field of detection devices, and discloses a portable optical glass blank thickness difference detection device. The portable optical glass blank thickness difference detection device comprises a detection table, clamping blocks and a storage box, the three clamping blocks are arranged on the detection table, adjusting grooves are formed in the clamping blocks, and positioning rods movably penetrate through the adjusting grooves, so that the clamping blocks can be moved to enable gaps among the three clamping blocks to be matched with glass in size, limiting blocks are loosened, and the clamping blocks can be clamped in the storage box. The elastic pieces can embed the clamping blocks into the corresponding clamping grooves through self elastic rebounding to fix the positions of the clamping blocks, at the moment, the clamping blocks are rotated, the positioning rods can be driven to rotate in the positioning grooves, the angle of the clamping blocks is matched with t
