The present invention relates to a folding trap, more specifically, the upper opening is cut through an incision opened and closed by a rubber band installed between the wires of the trap frame in the coil spring shape when feeding or replacing the inside of the trap. Significantly improves workability by shortening the time and effort required to inject or replace food into the inside of the container by allowing food to be quickly and easily inserted or replaced in the food bag installed inside the container to communicate with the department. In addition to allowing the food bag to be suspended from the inside of the keg to be fixed to the inside of the keg using the fixing straps attached to the keg frame, the attraction of the food can be improved to greatly increase the catch. It is about a folding trap to make it possible. The present invention is provided with a trapping frame (2) formed by winding a steel wire in a coil spring shape, the outer side of the trapping frame (2) is provided with a net (3) surrounding the outer peripheral surface of the trapping frame (2) and the trapping frame ( 2) both ends of the fish inlet (4) (5) is formed to be retracted toward the inside, respectively, and on the inner circumferential surface of the fish inlet (4) (5) is an inlet support frame (6) to maintain the shape of the fish inlet in a circle ( 7) are each installed and the tension straps (8) are coupled between the attracting support (6) (7) and the folding type configured to be installed on the end of the trap frame (2), the folding hook (9) In the trap, the cutout portion 10 which is opened and closed by a rubber band 11 provided between the steel wires of the trapping frame 2 is formed in the central portion of the outer peripheral surface of the net 3, the inner side of the cutout 10 There is a net of the upper opening is in communication with the incision (10) The needle 12 is suspended from the inside of the net 3, and the food bag 12 is suspended from the ins
