There are 3 radial grooves, slidably connect sliding seat in each radial groove, the sliding seat upper end sets that there are five threaded hole, institutes
It states claw bottom to be fixedly connected with threaded hole any on sliding seat, the claw is strip, and two lateral walls respectively offer
One mounting groove, rubber strip is respectively and fixedly provided in two mounting grooves, and the sliding seat lower end is equipped with several double wedges, the chuck parcel
Top is equipped with helicla flute, and several double wedges of the sliding seat lower end are located in the helicla flute of chuck parcel, chuck parcel bottom
Portion is equipped with annular cone tooth, and the annular cone tooth is engaged with the bevel gear.
Optionally, the outer casing bottom is also welded with connecting rod, and the connecting rod is welded with annulus far from one end of shell
Shape handle.
Optionally, the bevel gear end is equipped with rotating handle, and the rotating handle is equipped with anti-skid chequer.
Optionally, the capping is fixedly connected with shell by screw.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) the utility model drives chuck parcel to turn by the way that strip claw to be mounted on sliding seat by bevel gear
It is dynamic, and then sliding in the radial groove of sliding seat on the shell is driven, realize the self-centering movement of claw, and claw is installed
At the top of the sliding seat in different threaded holes, the components for being adapted to different spaces requirement are chosen, and improve working efficiency；
(2) rubber strip is arranged in the utility model on claw, can protect during choosing to component surface,
And process skidding of choosing can be prevented；
(3) the utility model uses three rotating handles, and anti-skid chequer is arranged on rotating handle, so that components clamping is more efficient
Fast.

Specific embodiment
The principles of the present invention and feature are described below in conjunction with example, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Picture 1-4 institute shown in, a kind of three-jaw self-centering chuck, including shell 1, capping 10, chuck parcel 9, bevel gear 8,
Claw 5, the chuck parcel 9 is mounted on inside the shell 1, in spy, 1 bottom opening of shell, and the capping 10
It being installed at 1 bottom opening of shell, 1 side wall of shell is evenly equipped with 3 mounting holes, it is mounted on bevel gear 8 in each mounting hole,
It is evenly equipped with 3 radial grooves at the top of the shell 1, slidably connects sliding seat 7 in each radial groove, on the sliding seat 7
End is set there are five threaded hole, and 5 bottom of claw is fixedly connected with any threaded hole on sliding seat 7, and the claw 5 is strip
Shape, and two lateral walls respectively offer a mounting groove, and rubber strip 6,7 lower end of sliding seat are respectively and fixedly provided in two mounting grooves
Equipped with several double wedges, helicla flute is equipped at the top of the chuck parcel 9, several double wedges of 7 lower end of sliding seat are located at chuck disk
