Summary of the invention
Structure is complicated and the lower technical problem of security performance aiming at existing drill chuck for the utility model, provides one kind
Structure is simple and the higher internal screw thread drill chuck of security performance.
For this purpose, the utility model is equipped with drill body, it is uniformly distributed circumferentially on drill body there are three locating slot, is equipped in locating slot
Clamping jaw, locating slot both ends are respectively equipped with drill body sliding slot on drill body, and clamping jaw both ends are equipped with the clamping jaw sliding slot matched with drill body sliding slot,
Clamping jaw is driven by clamping jaw sliding slot and drill body sliding；Housing is equipped with outside drill body, jacket internal circumferencial direction is equipped with sleeve thread,
Clamping jaw periphery is equipped with the clamping jaw screw thread being meshed with sleeve thread；Housing bottom end is equipped with fixing sleeve, housing and drill body and passes through admittedly
Fixed set connection.
Preferably, jacket internal is equipped with seperated set, and fission set is combined closely with outer casing inner wall, fission set inner wall circumferencial direction
Equipped with sleeve thread.
Preferably, bearing fit is equipped among housing and drill body.
Preferably, drill body bottom end is equipped with circlip, and circlip is stuck in the groove of fixing sleeve.
The utility model structure is simple, by the way that drill body sliding slot is arranged on drill body, and in the setting of clamping jaw both ends and drill body
The clamping jaw sliding slot that sliding slot matches, slides clamping jaw on drill body；By the way that sleeve thread is arranged in outer casing inner wall, and outside clamping jaw
The clamping jaw screw thread being meshed is arranged in disc, makes housing by way of screw-driven, and clamping jaw is driven to slide in drill body locating slot,
The circle surrounded by three clamping jaws of mobile diminution or increase of clamping jaw, so that drilling tool is clamped, it is practical and convenient, and clamping effect is good
It is good.

Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawings.
Embodiment 1
As shown in Figure 1, Figure 2 and Figure 3, the utility model is equipped with drill body 1, is uniformly distributed circumferentially that there are three fixed on drill body 1
Position slot 2, clamping jaw 3 is equipped in locating slot 2, and 2 both ends of locating slot are respectively equipped with drill body sliding slot 4 on drill body 1, such as Fig. 4, Fig. 5 and Fig. 6 institute
Show, 3 both ends of clamping jaw are equipped with the clamping jaw sliding slot 5 matched with drill body sliding slot 4, and clamping jaw 3 is passed by clamping jaw sliding slot 5 and the sliding of drill body 1
Dynamic, clamping jaw 3 can slide in the drill body sliding slot 4 on drill body 1；There is threaded hole at 1 rear portion of drill body, connect with electric drill host output shaft,
Driving drill body 1 drives three clamping jaws 3 and folded tool to rotate synchronously when host output shaft rotates.
As shown in Figure 7 and Figure 8, housing 6 is equipped with outside drill body 1,6 inner wall circumferencial direction of housing is equipped with sleeve thread 12, folder
3 periphery of pawl is equipped with the clamping jaw screw thread 7 that is meshed with sleeve thread 12, when housing 6 rotates, side that housing 6 passes through screw-driven
Formula drives clamping jaw 3 to slide in the locating slot 2 of drill body 1, is surrounded by three clamping jaws 3 of mobile diminution or increase of clamping jaw 3
Circle, to clamp drilling tool, sleeve thread is enclosed in the outside of clamping jaw 3 always, effectively enhances clamping effect.
6 bottom end of housing is equipped with fixing sleeve 8, and fixing sleeve 8 and the interference fit of outer rotary table 10 of 1 bottom end of drill body link together,
1 bottom end of drill body is equipped with circlip 9, and circlip 9 is stuck in the groove of fixing sleeve 8, and housing 6 is connect with drill body 1 by fixing sleeve 8；Housing 6
Cooperate with bearing 11 is equipped among drill body 1, can effectively reduce the frictional force that housing 6 and drill body 1 relatively move, improves drill chuck
Clamping torque input, to guarantee the clamping effect of drill chuck.
Embodiment 2
Remaining is same as Example 1, the difference is that, the set-up mode of sleeve thread 12 in housing 6, such as Fig. 9 and figure
Seperated set 13 is equipped with shown in 10, inside housing 6, fission set 13 is combined closely with 6 inner wall of housing, fission 13 inner wall circumferencial directions of set
Equipped with sleeve thread 12, fission set 13 and housing 6 use dismountable mode, convenient for assembly.
Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this
The range of implementation, therefore the displacement of its equivalent assemblies, or according to equivalent changes and modifications made by the utility model patent protection scope,
