Described tool housing groove ring diameter is more than drill headstock groove ring diameter, and on described tool housing, circumference is uniformly provided with multiple screwed hole, and this screwed hole communicates with tool housing groove ring；
The external diameter of described anticreep jump ring is equal with the big footpath of tool housing groove ring, the radial thickness of described anticreep jump ring is less than or equal to the degree of depth of drill headstock groove ring, and the path arc length of described anticreep jump ring opening portion is greater than the difference of its inside diameter hoop length and drill headstock groove ring path circumference.
The difference of the path arc length of described anticreep jump ring opening portion and its inside diameter hoop length and drill headstock groove ring path circumference is 3-8mm.
Described screwed hole is 3-6.
The beneficial effects of the utility model are: the anti-drop device of this torsion revolution speed-raising instrument that this utility model provides, it is possible to prevent torsion revolution speed-raising tool slippage, make drill headstock and the parts of tool interior, drill bit fall into shaft bottom, cause drilling failure.
Compared with prior art, having the advantage that simple in construction, compact, shear strength is strong, and reliability is high, assembles and dismounting simplicity.
It is described in further details below in conjunction with accompanying drawing.

Detailed description of the invention
Embodiment 1:
Present embodiments provide the anti-drop device of a kind of torsion revolution speed-raising instrument as shown in Figure 1, including tool housing 1 and the drill headstock 2 that is connected with tool housing 1 lower end, matched in clearance is adopted to connect between described tool housing 1 and drill headstock 2, described tool housing 1 lower end is provided with tool housing groove ring 3, described drill headstock 2 upper end is provided with drill headstock groove ring 4, is provided with anticreep jump ring 5 between described tool housing groove ring 3 and drill headstock groove ring 4；
Described tool housing groove ring 3 diameter is more than drill headstock groove ring 4 diameter, and on described tool housing 1, circumference is uniformly provided with multiple screwed hole 6, and this screwed hole 6 communicates with tool housing groove ring 3；
The external diameter of described anticreep jump ring 5 is equal with the big footpath of tool housing groove ring 3, the radial thickness of described anticreep jump ring 5 is less than or equal to the degree of depth of drill headstock groove ring 4, and the path arc length of described anticreep jump ring 5 opening portion is greater than the difference of its inside diameter hoop length and drill headstock groove ring 4 path circumference.
The principle of the anti-drop device of this utility model torsion revolution speed-raising instrument:
Such as Fig. 2, shown in 3, the outer diameter D 5 of anticreep jump ring 5 is consistent with the nominal dimension of the big footpath D3 of tool housing groove ring, after making anticreep jump ring 5 in loading tool housing groove ring, it is in free state, and there is centralizing function placed in the middle, the radial thickness (D5-D4)/2 of anticreep jump ring 5 is less than or equal to the degree of depth (D2-D1)/2 of drill headstock groove ring 4 simultaneously, as shown in Figure 4, the path arc length L of anticreep jump ring 5 opening portion is greater than the difference △ L of its inside diameter hoop length (π D4) and drill headstock groove ring 4 path circumference (π D1), make anticreep jump ring 5 can extrude completely in drill headstock groove ring 4.
The anti-drop device assembling process of the torsion revolution speed-raising instrument that the present embodiment provides:
During assembling, first anticreep jump ring 5 is squeezed into completely in drill headstock groove ring 4, tool housing 1 is loaded under squeezed state, when to tool housing groove ring 3 place, anticreep jump ring 5 springs open radially in entrance drill headstock groove ring 4 under natural resiliency effect, now owing to anticreep jump ring 5 radial thickness (D5-D4)/2 is more than the degree of depth (D3-D2)/2 of tool housing groove ring 3, so a part for anticreep jump ring 5 can in drill headstock groove ring 4, make drill headstock 2 and tool housing 1 not to disengage, form anti-drop device.Wherein, the nominal dimension of D5 and D3 is consistent.
During tool ejector, owing to the screwed hole 6 on tool housing 1 communicates with tool housing groove ring 3, by loading a screw at each screwed hole 6, anticreep jump ring 5 is got in drill headstock groove ring 4, then drill headstock 2 is exited.
Embodiment 2:
On the basis of embodiment 1, present embodiments providing the anti-drop device of a kind of torsion revolution speed-raising instrument, the difference of the path arc length of described anticreep jump ring 5 opening portion and its inside diameter hoop length and drill headstock groove ring 4 path circumference is 3-8mm；Anti-release clamp spring 5 can be made can to extrude completely in drill headstock groove ring 4, and be easy to handling.
In the present embodiment, on tool housing 1, circumference is uniformly provided with 3-6 screwed hole 6, and screwed hole 6 is M8、M10Or M12。
In sum, the anti-drop device of this torsion revolution speed-raising instrument that this utility model provides, it is possible to prevent torsion revolution speed-raising tool slippage, make drill headstock 2 and the parts of tool interior, drill bit fall into shaft bottom, cause drilling failure.Compared with prior art, having the advantage that simple in construction, compact, shear strength is strong, and reliability is high, assembles and dismounting simplicity.
Parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
