Housing is threadedly coupled by drill body screw thread with drill body, and outer casing inner wall is equipped with housing inclined-plane, is uniformly arranged on housing inclined-plane several oblique
Face groove, inclined plane groove are matched with steel ball, and the another side of steel ball is matched with clamping jaw.
Preferably, the number of clamping jaw is 3, and housing inclined-plane number is identical as clamping jaw number.
Preferably, inclined plane groove is axially arranged along housing.
Preferably, clamping jaw is equipped with positioning ball groove, and steel ball is matched with positioning ball groove.
Preferably, spring is arranged on clamping jaw, clamping jaw end face is arranged in one end of clamping jaw, and clamping jaw end face is matched with spring.
Preferably, drill body head is equipped with bearing, the axial setting clamping jaw plane of clamping jaw, and clamping jaw plane is matched with bearing.
Preferably, the screw thread that jacket internal has and drill body screw thread matches, housing pass through screw thread and drill body screw thread
Connection.
The configuration of the present invention is simple, drill body head outer circle have screw thread, and housing can be together by a threaded connection with screw thread,
Clamping jaw is fixed in drill body slot by housing, steel ball and spring, and housing can be moved forward and backward by the screw thread of drill body, to push
Clamping jaw is unclamped and is clamped；Positioning ball groove is equipped at the top of clamping jaw, so as to locking ball, steel ball rolling friction when this region clamps,
The frictional force on housing inclined-plane and clamping jaw when can reduce driving, bearing contact clamping jaw plane position always during jaw action,
Play the role of reducing friction, housing inclined-plane is equipped with inclined plane groove, can produce friction when steel ball rolls on inclined plane groove
Resistance can increase release torque, thus guarantee that clamped condition is more reliable, it is practical and convenient.

Specific embodiment
The specific embodiment that the present invention will be described in detail with reference to the accompanying drawings.
As depicted in figs. 1 and 2, the present invention includes drill body 1, clamping jaw 2, housing 8, steel ball 3, circlip 7 and rear cover 6, clamping jaw 2
Number is 3, and as shown in Figure 3 and Figure 4, clamping jaw 2 is respectively arranged at 3 be uniformly distributed circumferentially the drill body slot 1-1 on drill body 1
Interior, 1 rear end of drill body is fixed by circlip 7 and rear cover 6, realizes the axial fixation of drill body 1.
1 front end outer circle of drill body is equipped with drill body screw thread 1-2, has the screw thread 8- to match with drill body screw thread 1-2 inside housing 8
3, housing 8 is threadedly coupled by screw thread 8-3 with drill body screw thread 1-2, and housing 8 can be connected through a screw thread rotation and drive clamping jaw 2
To fast implement clamping and to unclamp operation, the purpose for improving torque of uncaging is realized.
As shown in Fig. 5, Fig. 6 and Fig. 7, clamping jaw 2 is equipped with positioning ball groove 2-1, and steel ball 3 is matched with positioning ball groove 2-1；Such as
Shown in Fig. 8, Fig. 9 and Figure 10,8 rear end inner wall of housing is equipped with jump-ring slot 8-4, realizes circlip 7 and housing 8 by jump-ring slot 8-4
Connection, 8 inner wall of housing are equipped with housing inclined-plane 8-1, are uniformly arranged several inclined plane groove 8-2, inclined plane groove 8- on housing inclined-plane 8-1
2 are arranged along the axial of housing 8, and inclined plane groove 8-2 is matched with steel ball 3, and the another side of steel ball 3 is matched with clamping jaw 2, housing 8
When rotating relative to special topic 1, housing inclined-plane 8-1 can play the role of oppressing or loosen steel ball 3, and inclined plane groove 8-2 can be played
Increase the effect of 3 frictional force of steel ball, to realize the effect loosened.
Spring 4 is arranged on clamping jaw 2, clamping jaw end face 2-2 is arranged in one end of clamping jaw 2, and clamping jaw end face 2-2 and spring 4 match
It closes, spring 7 acts on the 2-2 of clamping jaw end face, plays the role of convenient for the rebound of clamping jaw 2.
1 front end of drill body is equipped with bearing 5, and axial setting the clamping jaw plane 2-3, clamping jaw plane 2-3 and bearing 5 of clamping jaw 2 match
It closes, the frictional force of housing 8 during rotation can be effectively reduced.
As is illustrated by figs. 11 and 12, when housing 8 is rotated clockwise with respect to drill body 1, housing inclined-plane 8-1 oppresses steel ball 3, from
And steel ball 3 is oppressed clamping jaw 2 and is moved to 1 center of circle direction of drill body, steel ball 3 slides counterclockwise along housing inclined-plane 8-1, when 3 clamping jaws 2
I.e. reachable minimum grip range after contacting with each other.
Shown in Figure 13 and Figure 14, when housing 8 rotates counterclockwise relative to drill body 1, housing inclined-plane 8-1 no longer oppresses steel ball 3,
To make clamping jaw 2 move to 1 center of circle direction of drill body is detached from, steel ball 3 is along housing inclined-plane 8-1 slid clockwise, when 3 clamping jaws 2
It is reduced to and reaches maximum grip range afterwards to a certain degree；Spring 7 plays reversed supporting role, clamping jaw plane 2- in clamping process
3 are pressed in above the ball of at least 2 bearings 5 and steadily roll, and effectively reduce frictional force, it is anti-that inclined plane groove 8-3 can increase steel ball 3
The effect of pine, prevents from loosening in vibration processes；The purpose that clamp or release can be realized by less than 120 degree rotating jackets 8, has
Effect improves work efficiency.
Only as described above, only specific embodiments of the present invention, when the model that cannot be limited the present invention with this and implement
It encloses, therefore the displacement of its equivalent assemblies, or according to equivalent changes and modifications made by the invention patent protection scope, should still belong to this hair
The scope that bright claims are covered.
