The treatment head 110 is set to output radio frequency treatment signals;

The female plug 120 is arranged in the handle. The female plug 120 includes a first through hole 121. The treatment head 110 can be movably inserted into the first through hole 121 to electrically connect to the female plug. Pull out the first through hole 121 to be separated from the female plug 120, which is configured to transmit the radio frequency treatment signal to the treatment head 110 that is electrically connected;
