The invention discloses a rapping device. The rapping device comprises a rapping hammer capable of rotating, a hammer lifting module, a hammer falling module and a driving module; the hammer lifting module includes a rotating part, a swing arm and a return part; the rotating part can rotate; the swing arm is arranged on the rotating part in a swing manner; the return part normally drives the swing arm to locate in a hammer lifting position suitable for driving the rapping hammer to rotate; when the hammer lifting module rotates to a first position, the swing arm in the hammer lifting position drives the rapping hammer to rotate so as to lift up the rapping hammer; the hammer falling module is opposite to the swing arm; when the hammer lifting module rotates to a second position, the hammer falling module pushes the swing arm from the hammer lifting position to enable the rapping hammer to fall down; and the driving module is in transmission connection with the rotating part. According to the rapping device, the lifting and fall rapping of the rapping hammer can be realized, and the return part is provided for enabling the hammer lifting module to stably drive the rapping hammer, so that the working stability of the rapping device is improved.
