Description
Technical field
The utility model relates to a kind of hand fastening drill clutch, particularly relates to a kind of drill chuck being arranged on machining equipment and electric tool.
Background technology
in the past, be provided with drill body, jaw, nut, rear cover in hand fastening drill clutch, rotatable protheca, inner sleeve, inner sleeve was placed in protheca, and nut is placed in inner sleeve, and one holds rear cover, and another hand-screw turns protheca, drove nut clip locking drill chuck.Because hand-tight torsion is limited, under HI high impact effect, there is the phenomenon that drill jig does not live; And drill chuck invades in drill chuck due to silt ash after drilling, makes drill chuck be difficult to unload.
Summary of the invention
Technical problem to be solved in the utility model is to provide one and can clamps by secondary, and can be convenient to again the secondary clamped-in style hand fastening drill clutch unloading drill chuck, for this reason, the utility model provides following technical scheme:
A kind of hand fastening drill clutch, comprise drill body, jaw, nut, described nut is threaded with described jaw, hand fastening drill clutch also comprises driven wheel and face gear, described driven wheel is connected with drill body, and it is outer and coaxial with described drill body that described face gear is enclosed within drill body, and described driven wheel is provided with instrument connection bit, described instrument connection bit is exposed to the surface of described drill chuck, and described driven wheel engages with described face gear; Described face gear is connected with described nut by attaching parts, and drives described nut to rotate.
On the basis adopting technique scheme, the utility model also can adopt following further technical scheme:
Described driven wheel front portion is provided with connecting axle, and described drill body is provided with gear hole, and described connecting axle inserts described gear hole.
Described attaching parts are nut sleeve, and described nut sleeve is placed on outside described nut, and described nut sleeve is connected with described face gear.
Described face gear one side is provided with driver slot, and described nut sleeve rear is provided with driving pin, and described driving pin snaps in described driver slot and described nut sleeve is connected with described face gear.
Be provided with step in the middle part of described drill body, described face gear is mounted on described step.
Race ring is provided with between described face gear and nut.
Owing to adopting the technical solution of the utility model, the beneficial effects of the utility model are: drill bit obscission under minimizing HI high impact, and for convenience detach; Rely on gear to improve the torsion of input, drill bit is clamped more firm; Make hand-operated clamping drill bit more laborsaving, more easy to operate.

Detailed description of the invention
As shown in the figure, a kind of hand fastening drill clutch, comprises drill body 1, jaw 3, nut 2, protheca 8 is driven and drive nut 2 rotating clamp locking drill chuck by inner sleeve 81, driven wheel 4 and face gear 5, described driven wheel 4 is provided with instrument connection bit, and described instrument connection bit is used for being connected with die nut 7.Described driven wheel 4 front portion is provided with connecting axle 43, and described connecting axle 43 inserts the gear hole 11 on drill body, described driven wheel 4 and face gear 5 engagement rotation, and described die nut 7 is connected with driven wheel 4 rear; Described nut 2 cover has nut sleeve 84, and described nut sleeve 84 is connected with face gear 5.
Described face gear 5 one side is provided with driver slot 51, and described nut sleeve 84 rear is provided with and drives pin 841, and described driving pin 841 snaps in driver slot 51 and nut sleeve 84 is connected with face gear 5.
Described drill body top is provided with step 12, and described face gear 5 is mounted on the step 12 of described drill body.
race ring 6 is provided with between described face gear 5 and nut 2.
Nut sleeve 54 is enclosed within outside nut 2, and inner sleeve 81 is enclosed within outside nut sleeve 84, and protheca 8 is enclosed within outside inner sleeve 84, and rear cover 85 is located at above drill body 1.During use, one holds rear cover 85, and another hand-screw turns protheca 8, drives nut 2 to clamp jaw 3; Then die nut 7 is pulled, namely driven wheel 4 is pulled, driven wheel 4 drives face gear 5, rotate together with the nut sleeve 84 that face gear 5 connects, nut sleeve 84 drives nut 2 to rotate, thus drive nut 2 two clampings, utilize the mode of enlarging moment and driving force, drill bit can be clamped easily, and drill bit is not easily unclamped under the environment of HI high impact.
Also comprise in figure, protheca 8 front portion cover has sheathing 82; By jump ring 83 fixing for sheathing 82; Rear cover 85 is connected on drill body and overlaps 9.
