A jerking device for a fish box is provided to use the magnetic force of a magnet that does not get rusty and is able to be used semi-permanently and to prevent malfunction due to shock by installing a coupling tool inside a housing. A jerking device for a fish box includes a housing(10), an ascending/descending magnet(20) and a coupling tool(30). The housing is connected to a third string(34) that is connected to a fishing rod. Upper and lower magnets(12,13) are formed at the upper and lower ends of an inner hollow hole(11) of the housing. The ascending/descending magnet is coupled to be able to ascend and descend between the upper and lower magnets and is connected to a second string(32) having a fishing needle at the lower end. A first string(31) connected to the second string is coupled to the coupling tool.
