Preferably, the quantity of the fluting is three；

Preferably, the outer surface at the elastic clamping end is additionally provided with the tapered slope moved up and down convenient for interior six square nut One；

Preferably, the outer six square nuts seal face is tapered slope；

Preferably, the upper inner of outer six square nut is equipped with the cone being connected with outer six square nuts seal face Shape inclined-plane two, lower end are equipped with the internal thread being connect with interior six square nut；The outer surface of outer six square nut is to be matched with die nut Positive hex surface；

Preferably, the outer surface upper end of interior six square nut is equipped with the external screw thread being connect with outer six square nut, lower end Equipped with the matched positive hex surface of die nut.

With the above structure, a kind of high-precision fast assembling-disassembling collet described in the utility model, has the following advantages：

1, in drill sleeve and outer six square nuts, six square nuts are sealed using compression type, can effectively prevent because of drill sleeve inner wall It is untight to solve the problems, such as that drill bit is connect with drill sleeve using the closing component structure of compression type for disconnection phenomenon that is thin and generating；

2, nut and the nut dismounting solved on the market needs specific dismantling device just to can be removably mounted, and use scope is small Problem can have a wide range of application with being dismounted on the market with die nut；

3, under conditions of not changing interior six square nuts and outer six square nuts, situation different inner diameters can be replaced according to demand The drill sleeve of size and the drill bit of various outer diameter reach better general interchangeability.
