Description

A kind of cutter

Technical field

The utility model relates to a kind of cutter that cuts usefulness.

Background technology

The present employing drill chuck that generally mostly is carries out clamping.But clamping speed and instrument unhappy and need be special.Inconvenient when using the same train product and often changing product.

Summary of the invention

The utility model technical problem to be solved is that to solve drill chuck clamping speed slow and need the technical problem of instrument, and a kind of cutter is provided, and is fit to very much the installation way that same train is often changed product.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this cutter; Comprise cutter hub position, handle of a knife position, it is characterized in that the cutter hub position is provided with the cutter hub hole, the cutter hub hole is provided with an above salient point; The handle of a knife position is provided with one with upper groove; A groove is provided with the handle of a knife hole, places spring and ball in the handle of a knife hole, the identical and position cooperation of quantity of salient point and groove.

The quantity of the utility model salient point and groove is three and configuration along the circumferential direction equably.

The utility model is simple for structure, and clamping speed is fast, and is easy to use.

The specific embodiment

Referring to Fig. 1, Fig. 2, the cutter hub position 1 of the utility model embodiment is provided with cutter hub hole 2, and cutter hub hole 2 is provided with salient point 3, and present embodiment has three salient points that are uniformly distributed with 3.

Referring to Fig. 3, Fig. 4, the handle of a knife position 4 of the utility model embodiment is provided with groove 5, and groove 5 axially is provided with earlier on cylinder, becomes the circumference setting behind the certain-length, and three grooves 5 are distributed on the shank cylinder.Wherein a groove 5 is provided with handle of a knife hole 6, in handle of a knife hole 6, places spring 7 and ball 8.Ball 8 is higher than groove 5 under the elastic force effect of spring 7.The quantity of salient point 3 and groove 5 is identical and the position is corresponding.

In use: the groove 5 that the salient point 3 in the cutter hub position 1 is aimed at handle of a knife position 4 is inserted in the handle of a knife.Circular motion is made in rotation again after axial displacement can't be moved.When salient point 3 continues rotation through the ball 8 at handle of a knife positions 4 and the elastic force that overcomes spring 7, the afterbody of contact groove 5 is accomplished with regard to clamping like this.Not spacing in time spent ball 8 and spring 7 elasticity.It is just passable with the elastic force counter motion of spring 7 to overcome ball 8 in the time of need unloading.

The utility model can be realized quick-clamping, and does not need instrument.

The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought the protection domain that falls into the utility model.

Claims (2)
