Embodiment
The utility model is described in further detail below in conjunction with Figure of description, and provides embodiment.
As shown in figs. 1-7, a kind of dental handpiece handle casing structure of the utility model, including back casing 1 and after being connected to
The head shell 2 of the front end of housing 1, is plugged with the preceding inner core 3 and rear inner core 4 of integral type setting in back casing 1, preceding inner core 3 it is outer
Wall is in close contact with the inwall of back casing 1, and the outer wall of rear inner core 4 leaves space, preceding inner core 3 and rear inner core 4 with the inwall of back casing 1
Inside be provided with air flue 5, water channel 6, blower wheel air flue 7 and the exhaust duct of connection, back casing 1 close to head shell 2 one
End be provided with bending section 8, the inner side integral type of bending section 8 is provided with connector 9, be provided with connector 9 respectively with air flue 5,
