It is individual to help part and garter spring, in the centre bore that the support part reaches drill body from the guide through hole；
The multiple support part is pushed from garter spring hoop in guide through hole and to centre bore.
On the basis of using above-mentioned technical proposal, the utility model can also use technical scheme further below, or
These solution pools are used：
Drill body front portion outside wall surface is provided with annular groove, and the drill body opens up the radiation in annular groove to centre bore direction
The guide through hole of shape arrangement, the annular groove is used to position garter spring.
The afterbody for helping part has the locating slot being adapted to garter spring, and the front portion of the support part is
Pointed shape, the multiple support part offseted using pointed shape and with centre bore concentric locating, before the support part
Portion upside is inclined-plane, and the introducing port of drill bit is formed by the inclined-plane of the multiple support part.
The drill chuck is provided with the protheca being axially located, and the rotary sleeve is in the rear of protheca；The protheca and rotation
Pivoted housing clamping.
The drill chuck is provided centrally with 3 support parts around drill chuck.
The rear end of the rotary sleeve is connected with clamping ring, and location structure is provided with the clamping ring, with pistol electric drill
On liftable location structure coordinate, prevent rotary sleeve from rotating.
Due to using the technical solution of the utility model, the utility model helps drill bit structure simple, in drill chuck connection
Without holding drill bit with hand steered during drill bit, and drill bit structure is helped to help by drill point is procephalic, rapid operation, and can be further real
Now automatically exempt from the function that hand operation clamps drill bit.

Specific embodiment
Referring to the drawings.Drill chuck provided by the utility model includes drill body 1, nut 2, clamping jaw 3 and rotary sleeve 7, described
Rotary sleeve 7 is connected by attachment structure and nut 2, and the attachment structure can be key to be connected with the cooperation of groove, interference, by oneself
The various ways such as lock construction part connection.
The structure for helping drill bit is set in the drill chuck, and the structure of the support drill bit is used in drill point head clamping drill bit
When to drill bit rise supporting role, release held with hand steered, it is described help drill bit structure support drill bit position A be in clamping jaw clamp bore
The rear of head position；
The hole wall of centre bore 10 of the drill body is provided with the guide through hole 11 of radial arrangement, the structure bag of the support drill bit
Multiple support part 8 and garter springs 9 are included, the support part 8 is reached in drill body from the guide through hole 11
In heart hole 10；
The multiple support part 8 is pushed from garter spring hoop in guide through hole 11 and to centre bore 10, described
Garter spring can either simultaneously constrain the multiple of scattering device in annular region and help parts 8, can have again it is suitable without
To too big force value so that more comfortable during operation, drill bit position is helped easily to open and can be automatically switched off, and annular
Positioning and installation of the helical spring in drill chuck facilitate.
