The structural body 100 has a flat connection end surface 110, and the structural body 100 is provided with a first jack 120, a second jack and a third jack 140 on the connection end surface 110, and because the existing dental handpiece needs to perform water outlet, air blowing or suction to the oral cavity of a patient, and part of tools need to be driven in a pneumatic or electric mode, the optical fiber handpiece female connector 20 needs to have configurations of water communication, air communication, power supply and the like. To this end, in the present embodiment, the first receptacle 120 may be defined for water passage, the second receptacle may be defined for ventilation, and finally the third receptacle 140 may be defined for power passage.
