The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail.
Fig. 1 to Fig. 5 has schematically shown the structure according to the high speed dental turbo mobile phone clamping car needle device of a kind of embodiment of the present utility model.
Extremely shown in Figure 5 as Fig. 1, a kind of high speed dental turbo mobile phone clamping car needle device, comprise and strut part 1, holder 2 and axle sleeve 3, axle sleeve 3 is provided with the columniform inner chamber 4 of inner one-tenth, inner chamber 4 bottoms are provided with and are communicated with outside spacing hole 5, strut in part 1 and the holder 2 embedding inner chambers 4, strut part 1 and be located at the bottom of inner chamber 4, strut part and comprise part main body 17, push inclined-plane 6 and press press button 18, extruding inclined-plane and be located at the two ends of part main body 17 by press button 18 respectively, one section by press button 18 is passed spacing hole and protrudes from axle sleeve, extruding inclined-plane 6 is inverted cone surface, holder 2 is provided with endoporus 7, one end of holder 2 is provided with the groove 8 that is squeezed, the groove 8 that is squeezed is arc, the sidewall of endoporus 7 is provided with U-shaped hole 9, U-shaped hole 9 is communicated with the groove 8 that is squeezed, the endoporus 7 of holder 2 is provided with folder pin position 10 near the groove 8 place ends that are squeezed, endoporus 7 also comprises pilot hole 11 and clearance position 12, and clearance position 12 is located at the middle part of endoporus 7, and folder pin position 10 and pilot hole 11 are located at clearance position 12 two ends, the diameter at folder pin position 10 is less than the diameter of pilot hole 11, the diameter of pilot hole 11 is less than the diameter of clearance position 12, and an end of pilot hole 11 is provided with chamfering 13, and the middle part of inner chamber 4 is provided with the chamber 14 of stepping down of annular.
