Connect, joint is provided with air inlet and atomization water pipe installing hole, air inlet is corresponding with air inlet pipe, one end of water pipe is atomized located at atomization
In water pipe installing hole.Thus, be provided with joint, the connection of handle and other workpieces can be facilitated, facilitate in handle air inlet and
It is passed through atomized water.
In some embodiments, high pulling torque holes dental handpiece includes bonnet, and bonnet is mutually covered with head.Thus, if
There is bonnet, the globality of high pulling torque holes dental handpiece can be improved, and can prevent chip from entering in movement.
In some embodiments, the excircle flush of the excircle of wind wheel and movement.Thus, increase the outer of wind wheel
Footpath, so as to improve the moment of torsion of wind wheel, improves stability when car pin is rotated.
In some embodiments, movement includes sleeve, and one end of car pin is set in wind wheel by sleeve, the bottom of sleeve
End is provided with inclined side.Thus, the locking that sleeve can be realized to car pin is provided with, prevents car pin from flying out when in use, it is ensured that to make
Use safety.
Description of the drawings
Fig. 1 is the cross section structure diagram of high pulling torque holes dental handpiece of the present utility model；
Fig. 2 is the structural representation at the one of visual angle of high pulling torque holes dental handpiece of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail.
See figures.1.and.2：High pulling torque holes dental handpiece, including handle 1, head 2, movement 3 and car pin 4, head 2 with
One end of handle 1 is connected, and movement 3 is provided with wind wheel 5 in movement 3 in head 2, and one end of car pin 4 is set in wind wheel 5,
Atomization water pipe 6 and return duct 7 is provided with handle 1, and the one end for being atomized water pipe 6 is located at 2 side of head, return duct 7 and atomization water pipe 6
It is connected, return duct 7 is located at the lower section of atomization water pipe 6 so that water enters directly into return duct 7 when flowing back, without entering into
In atomization water pipe 6.Wherein, the excircle flush of the excircle of wind wheel 5 and movement 3.
High pulling torque holes dental handpiece also includes air inlet pipe 8, air inlet pipe 8 in the handle 1, one end of air inlet pipe 8 and wind
Take turns 5 corresponding, i.e., the gas that the gases at high pressure that air inlet pipe 8 is entered are entered drives wind wheel 5 to rotate.
