Utility model content
In sum, for overcoming the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of mechanism of automatic clamping dental handpiece car pin.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of mechanism of automatic clamping dental handpiece car pin, comprise axle sleeve, pressing piece, be provided with one section of inwall with tapering in the bosom position of described axle sleeve, the lower end of described pressing piece is provided with the position of tapering in described axle sleeve, the upper end of described pressing piece extends up to the outside of described axle sleeve, and described pressing piece can do along described axle sleeve the slip of upper and lower displacement;
The sidewall of described pressing piece lower end has the clamping hole being oppositely arranged, at described clamping hole, place is provided with holder, described holder has the tapering matching with described sleeve lining, and the upper end of described holder is through described clamping hole in described pressing piece, and the lower end of described holder is between described axle sleeve and described pressing piece;
Position in described axle sleeve corresponding to described pressing piece bottom is provided with spring, and the bottom that this spring props up described pressing piece makes described holder clamp the car pin in described pressing piece inside.
The beneficial effects of the utility model are: use the mode clamping trolley pin of two lobe springs, only need on the pressing piece of tubulose, output two grooves is holding tank. Compare the mode of three traditional lobe spring clampingc car pins and open less a groove, processing technology is simplified greatly, and cost declines to a great extent. Below pressing piece, be provided with the spring that increases chucking power, make chucking power also can reach the chucking power size of three lobe spring clampingc car pins simultaneously.
On the basis of technique scheme, the utility model can also do following improvement:
Further, described spring bottom is enclosed within outside the top of meson, and this meson is fixed in described axle sleeve, and described meson middle part is provided with the guide through hole of car pin being inserted to described pressing piece inside.
Above-mentioned further beneficial effect is: car pin, under the guiding of meson, is more easily inserted into the inside of pressing piece through spring.
Further, the lower end of described pressing piece is provided with step, and described spring props up described step.
Brief description of the drawings

Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As illustrated in fig. 1 and 2, a kind of mechanism of automatic clamping dental handpiece car pin, comprises axle sleeve 1 and pressing piece 2, and the lower end of described pressing piece 2 is provided with step 9. Be provided with one section of inwall with tapering in the bosom position of described axle sleeve 1, the lower end of described pressing piece 2 is provided with the position of tapering in described axle sleeve 1, the upper end of described pressing piece 2 extends up to the outside of described axle sleeve 1, and described pressing piece 2 can do along described axle sleeve 1 slip of upper and lower displacement.
The sidewall of described pressing piece 2 lower ends has the clamping hole 3 being oppositely arranged, at described clamping hole, 3 places are provided with holder 4, described holder 4 has the tapering matching with described axle sleeve 1 inwall, and the upper end of described holder 4 is through described clamping hole 3 in described pressing piece 2, and described spring 5 props up described step 9. Use the mode clamping trolley pin 4 of two lobe springs, only need on the pressing piece of tubulose 2, output two grooves is clamping hole 3. Compare the mode of three traditional lobe spring clampingc car pins and open less a groove, processing technology is simplified greatly, and cost declines to a great extent.
Position in described axle sleeve 1 corresponding to described pressing piece 2 bottoms is provided with spring 5, and the bottom that this spring 5 props up described pressing piece 2 makes described holder 4 clamp the car pin 6 in described pressing piece 2 inside. The utility model uses two lobe spring clamping trolley pins, chucking power can decline to some extent relatively, in order to make movement have larger chucking power, below pressing, use the good spring 5 of elasticity to withstand pressing piece 2, make chucking power also can reach the chucking power size of three lobe spring clampingc car pins.
Described spring 5 bottoms are enclosed within outside the top of meson 7, and this meson 7 is fixed in described axle sleeve 1, and described meson 7 middle parts are provided with the guide through hole 8 of car pin 6 being inserted to described pressing piece 2 inside. Car pin 6, under the guiding of meson 7, is more easily inserted into the inside of pressing piece 2 through spring 5. While taking out the car pin 6 being clamped in axle sleeve 1, press down pressing piece 2 Compress Springs 5 and drive holder 4 to bottom offset, unclamp car pin 6 thereby strut the holder 4 being oppositely arranged, finally take out car pin 6 and just can.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
