The protheca 119 being fixedly connected with precursor 101 and the rear enclosure 121 being fixedly connected with rear body 100, do free relative rotation, rear enclosure
121 are rotated by the drive bevel gear 108 on body 100 after the drive of upper shield 123, and drive bevel gear 108 drives driven wheel of differential 105
It rotates, the cooperation driving jaw action of external screw thread 109 on the internal screw thread and clamping jaw in the gear hole of driven wheel of differential 105 makes to press from both sides
Pawl moves up and down in clamping jaw slideway 103, clamps drilling tool and works, or, drilling tool is unclamped after work replaces other drilling tools.It needs
It is noted that drilling tool receiving hole 127 is connected with rear 100 accommodating hole of body, and it is coaxially disposed.
When starting keyless drill chuck work, the external equipment of body 100 after connection passes through the drilling tool on keyless drill chuck
Working face is in contact with the working face of product to be processed, when external equipment to after body 100 apply the working face to product to be processed
Axial force when, cause rear body 100 to move along the direction where axial direction to the working face of product to be processed, compress the first elastic component
125, drive the second end face gear 118 being fixedly connected with rear body 100 to move, to make second end face gear 118 and first end
Face gear 117 is at a fully engaged.
In the keyless drill chuck course of work, when keyless drill chuck rotates forward work, and in first end face gear 117 and the
In the case that the tooth of biend gear 118 is ratchet, first end face gear 117 and second end face gear 118 can rotate forward super
More, so that reaching for the clamping force to drilling tool of keyless drill chuck is maximum, drilling tool is clamped tighter, can guarantee that drilling tool is working
When it is non-slip, and smoothly complete work.
It is at a fully engaged and can not exceed when keyless drill chuck needs to invert work in the keyless drill chuck course of work
First end face gear 117 and second end face gear 118 more, the precursor 101 being fixedly connected respectively with them, rear body 100 are consolidated
Surely it is integrally formed, favorably accomplishes the work of reversion, be not in keyless drill chuck currently on the market in the case where reversion,
Radial rotating between precursor 101, rear body 100 and cause clamping jaw to unclamp drilling tool, the case where work cannot be inverted.
Thereby realizing keyless drill chuck both has the easy to operate and forward and backward of hand-tight keyless drill chuck can work
The characteristic of work, non-slip, product itself service life when also there is the hand-tight big clamping force not having with spanner keyless drill chuck, work
Long feature.Blank in the market is filled up.Both had the advantages that all of hand-tight keyless drill chuck, and also solved hand-tight and spanner
Maximum disadvantage existing for keyless drill chuck.
Embodiment two
Keyless drill chuck in the present embodiment two is improvement on the basis of embodiment one, technology disclosed in embodiment one
Content not repeated description, one disclosure of embodiment also belong to the present embodiment disclosure.
In the embodiment, end cap 110 is structure as a whole with the first driving section, i.e., end cap 110 is with first end face gear 117
Integral structure；The annular end face tooth of first end face gear 117 is just located on the end face of the axially-extending portion of end cap 110.
Since end cap 110 and the first driving section are structure as a whole, in this embodiment, the first elastic component 125 and
Two elastic components 126 whether there is or not and its installation site can change accordingly.For example, with reference to shown in Fig. 6 and Fig. 7, when only retaining first
Elastic component 125, and when saving the second elastic component 126, the first elastic component 125 are located at the hole of the big part 113 in aperture of stepped hole
Between bottom and the end face in the axial limiting portion 112 of rear body 100.Referring to shown in Fig. 8 and Fig. 9, when only retaining the second elastic component 126,
And when saving the first elastic component 125, the internal diameter of the second elastic component 126 is greater than the overall diameter of the axially-extending portion 128 of end cap 110,
Second elastic component 126 is set in the axially-extending portion of end cap 110.
Embodiment three
The present embodiment three also provides a kind of keyless drill chuck, and the keyless drill chuck of the embodiment describes described first and passes
Another implementation of the installation site in dynamic portion and the second driving section, the technical solution of embodiment one in addition to this also belong to
The embodiment is not repeated to describe.
Referring to shown in Figure 10 to Figure 13, in the embodiment, the big part 113 in aperture of stepped hole is arranged in the first driving section
Bottom hole, the end face in the axial limiting portion 112 of rear body 100 is arranged in the second driving section.That is, the setting of first end face gear 117 exists
The end in the axial limiting portion 112 of rear body 100 is arranged in the bottom hole of the big part 113 in the aperture of stepped hole, second end face gear 118
Face.The bottom hole of the part 113 big with the aperture of stepped hole of first end face gear 117 is structure as a whole, second end face gear 118 with
The end face in the axial limiting portion 112 of body 100 is structure as a whole afterwards.
In the optional scheme of the embodiment, the internal diameter of the first bullet part part is greater than the overall diameter of the first driving section, and such first
After elastic component 125 is mounted on the bottom hole of the big part 113 in aperture of stepped hole, the first driving section and the second driving section will not influence
Between meshing relation.
It should be noted that in this embodiment, since the installation site of the first driving section and the second driving section has occurred
Change, therefore the second elastic component 126 can be saved.
Example IV
The present embodiment four provides a kind of drill kind tool, any embodiment offer into embodiment three including embodiment one
Keyless drill chuck.
In conclusion the method and brill class of keyless drill chuck provided in an embodiment of the present invention, keyless drill chuck Double-directional rotary
Tool is that rear body 100 in the axial direction can be limited with precursor 101 with the maximum difference of keyless drill chuck in the market
Axial movement；The first elastic component 125 is equipped between precursor 101, rear body 100 and/or in first end face gear 117 and second
The second elastic component 126 is set between face gear 118.In the case where two elastic components act on, 117 He of first end face gear is realized
Second end face gear 118 drill chuck is static loosen in the state of, it is completely disengaged；It is fully engaged at one again in the case where work
It rises, thus after realizing the precursor 101 being fixedly connected with first end face gear 117 and being fixedly connected with second end face gear 118
Body 100 be free to forward and reverse rotation in the state that keyless drill chuck is static or loosens, and reach the mesh of replacement drilling tool
's；First end face gear 117 and second end face gear 118 again at a fully engaged in the state of keyless drill chuck work, and divide
Precursor 101, rear body 100 are not connected and be combined, the work of drill chuck forward and backward freely may be implemented.
In conclusion the arrangement of clutch of keyless drill chuck provided in an embodiment of the present invention can be set rear body and precursor it
