The invention discloses a crabbing trap structure. The crabbing trap structure comprises an upper support ring, a lower support ring and a chassis, wherein an upper netting enclosure is connected between the upper support ring and the lower support ring, a lower netting enclosure is connected between the lower support ring and the chassis, a cage body is formed by the upper and lower support rings, the chassis and the upper and lower netting enclosures, a floating disc sleeves the outer side face of the upper support ring, a plurality of crab inlets are formed in the side face of the upper netting enclosure in the cage body, the bottom of each crab inlet is connected with a solid rubber side, a rotating shaft is rotatably mounted on the inner side face of each solid rubber side, the rotating shafts are separately fixedly connected with crab inlet plates horizontally, the top face of each crab inlet plate is coated with a fluorescent material, and an anti-crawl plate is rotatably mounted on the lower support ring. According to the crabbing trap structure, the structural design is reasonable, and crabs can be effectively crabbed by using phototaxis characteristic of the crabs, so that the crabbing trap structure has the advantages of good crabbing effect and convenience in use.
