摘要： Disclosed is a coupling device which makes possible to connect various agricultural implements or apparatuses to the rear end of a tractor, particularly to a coupling device which has wider handhold area for a lock so that mobility occurred by external impact may be reduced to have excellent binding power, has no space between the lock and bearing ball in coupled condition so that damages from shake or disconnection of the bearing ball is effectively prevented, and has an opening lever enabling easy-unlocking as well as maintaining the unlocked state without disconnection temporarily. The coupling device according to the present invention comprises: a coupling device housing attached to a tractor connector, which has a bearing recess for receiving a bearing ball adjacent to a receiving part on one side; a sliding lock spring-loaded towards a guide groove of the receiving part, which controls the lock or unlock of the bearing ball by selectively sliding upward or downward along the guide groove; a cam rotatably connected to the receiving part, unlocking the sliding lock by pushing it downward with the lower load, according to the selective rotational movement; and a lever rotatably connected to the upper part of the cam, rotating the upper load of the cam to a certain direction by selective rotational operation.
