A kind of cartridge device, comprising: the outer sleeve of inner clip cylinder and sheathed described inner clip cylinder; The first end of described inner clip cylinder offers external screw thread, offers the internal thread with described external thread bolt connection in described outer sleeve; Second end of described inner clip cylinder is provided with some gripping sections, and some described gripping sections are uniformly distributed around the central shaft of described inner clip cylinder; The second end near described inner clip cylinder in described outer sleeve offers the first chamfering, described gripping section offers second chamfering of mating with described first chamfering, to make at described external screw thread gradually with the process of described internal screw-thread screw, some described gripping sections are subject to the extruding of described outer sleeve and tighten up.
Wherein in an embodiment, some described gripping sections are regular prism structure away from the piece piece of described second chamfering.
Wherein in an embodiment, the number of described gripping section is three, and three described gripping sections are positive six prism structures away from the piece piece of described second chamfering.
Wherein in an embodiment, the outer wall of outer sleeve is provided with retaining structure.
Wherein in an embodiment, the cross section of retaining structure is regular hexagon shape.
Above-mentioned cartridge device structure is simple, by the instruments such as drill bit to be installed, milling cutter are inserted inner clip cylinder between some gripping sections, turn inner clip cylinder, make external screw thread gradually with internal screw-thread screw, by the effect of the first chamfering and the second chamfering, make some gripping sections be subject to outer sleeve extruding and tighten up gradually, realize by the instrument such as drill bit, milling cutter firmly and stably clamp, be convenient to install.By oppositely turning inner clip cylinder, some gripping sections being opened gradually, the instrument such as drill bit, milling cutter can be taken off, be convenient to dismounting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cartridge device of the utility model one embodiment;
Fig. 2 is the sectional view of cartridge device shown in Fig. 1.
Detailed description of the invention
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.Preferred embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present utility model more comprehensively thorough.
As depicted in figs. 1 and 2, the cartridge device 10 of the utility model one preferred embodiment, comprising: the outer sleeve 12 of inner clip cylinder 11 and sheathed inner clip cylinder 11.
The first end outer wall of inner clip cylinder 11 offers external screw thread 111, the inwall of outer sleeve 12 offers the internal thread 121 be spirally connected with external screw thread 111.Second end of inner clip cylinder 11 is provided with some gripping sections 13, and some gripping sections 13 are uniformly distributed around the central shaft of inner clip cylinder 11, and in the present embodiment, some gripping section 13 and inner clip cylinder 11 are formed in one structure.The position of the second end near inner clip cylinder 11 on the inwall of outer sleeve 12 offers the first chamfering 122, gripping section 13 offers second chamfering 131 of mating with the first chamfering 122.In actual applications, to install drill bit 20, first drill bit 20 to be installed is inserted inner clip cylinder 11 between some gripping sections 13, then turn inner clip cylinder 11, external screw thread 111 is screwed togather with internal thread 121 gradually, in the process, by the effect of the first chamfering 122 and the second chamfering 131, make some gripping sections 13 be subject to outer sleeve 12 extrude and tighten up gradually, thus realize by drill bit 20 firmly and stably clamp, be convenient to install.When drill bit 20 is taken off from cartridge device 10, only need oppositely turn inner clip cylinder 11, some gripping sections 13 be opened gradually, drill bit 20 can be taken off, be convenient to dismounting.
