Fig. 1 partly cuts open schematic diagram for a kind of embodiment of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
Fig. 4 partly cuts open schematic diagram for the another kind of embodiment of the utility model.
The specific embodiment
With reference to accompanying drawing.The connector 3 that the utility model is provided with jaw 2 and is connected with driving device, it also is provided with and is centered around the outer rotatable collet body that axially is positioned 1 of connector, described collet body is provided with the jaw groove 11 of inclination, jaw is located in the jaw groove, the front end of collet body has the hole 12 of stretching out for jaw, jaw is threaded with the connector front end, the periphery of described jaw body is provided with loss of weight district 13, described drill chuck is provided with the shell 10 that is connected with collet body outside corresponding loss of weight district, have loss of weight chamber 100 between shell and the collet body.
Connector has central through hole 32, and is connected with driving device by this hole.Totally 3 of jaws, corresponding jaw groove 11 also are 3 and evenly are provided with along the collet body circumferencial direction.The connecting thread of jaw and connector front end is a reverse thread.Drawing reference numeral 31 is the tapered thread that the connector front end is connected with jaw.
In the present embodiment, for the convenience of assembling and be convenient to develop multi-functional mechanism, also be provided with the back cover 4 that is centered around outside the connector at the collet body rear, collet body is connected with the back cover, collet body and back cover adopt and are threaded in the present embodiment, the rear portion of connector is provided with positioning boss, makes collet body and back cover be axially located.
In the present embodiment, the neighboring, middle part of connector cooperates with the centre bore of collet body location, and like this, the centralized positioning of collet body is simple in structure, assembles also very convenient.
In the present embodiment, accompany the round element 6 that periphery has spring leaf 61 between the back cover at positioning boss and positioning boss rear portion, spring leaf has self-locking position 62, and described back cover inwall is provided with the groove 41 that cooperates with spring leaf self-locking position.Like this, make the utility model also possess auto-lock function, no matter drill chuck rotates and reverse, and can both guarantee the clamping of jaw to drill bit.Drawing reference numeral 5 is the ball between round element and the back cover, and groove 41 can adopt V-shaped groove.
For the convenience of operating, present embodiment also is provided with the fixed cover 7 that can not rotate relative to connector in the outside of back cover.Drawing reference numeral 8 is the location jump ring.
As shown in figs. 1 and 4, the loss of weight district 13 of collet body periphery can be an annulus around the collet body surface, and corresponding, shell 10 is the shell-like housing and is centered around annular loss of weight district, and the loss of weight chamber 100 between shell and the collet body also is an annular chamber.As shown in Figure 1, loss of weight district 13 can only be on the segment length of collet body; As shown in Figure 4, loss of weight district 13 can be in collet body on the total length in cover the place ahead, back.
The loss of weight district can also the surface that along the circumferential direction is distributed in collet body in the form of slot, and at this moment, described shell both can be to be the shell-like housing, also can be the sheet that cooperates with notch shape.
Loss of weight district groove in the form of a ring is distributed in the surface of collet body vertically, and at this moment, described shell both can be to be the shell-like housing, also can be the ring-type with the endless groove form fit.
In force, can carry out anti-skidding processing and strengthen processing in case surface, such as strengthening rib strip, anti-skidding rib are set.
