Abstract
The utility model provides a kind of hand fastening drill clutch, including drill body, nut, clamping jaw, and the middle part of the drill body sets support level, places pad on support level, it is characterised in that the drill chuck is provided with anti-tilt nut structure between nut and pad.The utility model is simple in construction, easily manufactured, anti-oblique by setting anti-tilt nut structure to carry out nut between pad and nut, can effectively prevent that the phenomenon that clamping jaw drops occurs when clamping jaw from backing to the limit.
Description
Technical field
It the utility model is related to hand fastening drill clutch.
Background technology
Hand fastening drill clutch is one kind in conventional drill chuck, and it directly rotates drill chuck rotary sleeve to be revolved using hand
Pine tightens operation, and it includes drill body, nut, clamping jaw, and clamping jaw tilts and is provided with external screw thread and is connected with nut, passes through rotation
Overcoat come drive nut rotation and and then drive clamping jaw advance, retreat.The drill body at traditional hand fastening drill clutch, nut and its rear
Pad is set between support level, and pad is fixed on drill body by interference fit or clamping or other anti-rotation structures.
Find in use, when clamping jaw backs to the limit, it is possible to the phenomenon that clamping jaw drops occurs；Especially work as drill body
It is not provided with nut groove and the step of holding nut is only set, by the platform for being in holding nut on its anterior other parts and drill body
Rank coordinates when carrying out axially position nut, it is easier to this clamping jaw occurs and drops phenomenon.
The content of the invention
Technical problem to be solved in the utility model be to provide it is a kind of it is simple in construction, can prevent that above-mentioned clamping jaw from dropping phenomenon
Hand fastening drill clutch.Therefore, the utility model uses following technical scheme：
Hand fastening drill clutch, including drill body, nut, clamping jaw, the middle part of the drill body set support level, put on support level
Put pad, it is characterised in that the drill chuck is provided with anti-tilt nut structure between nut and pad.
On the basis of using above-mentioned technical proposal, the utility model can be also used using technical scheme further below
Or use is combined to these technical schemes：
Nut limited step is set on the pad or nut position-limited edge is set as anti-tilt nut structure.
The stamped single piece for forming band edge of the pad, the side is as the nut position-limited edge.
The radial direction that the nut limited step or nut position-limited edge are wrapped in the paired nut of nut profile is spacing.
The bottom of the nut sets limited step or sets position-limited edge, and the limited step or position-limited edge coordinate with pad
As anti-tilt nut structure.
The radial direction that the limited step or position-limited edge are wrapped in the paired nut of pad profile is spacing.
The bottom of the nut sets spacing annular groove, and the positive stop key coordinated with spacing annular groove is set on the pad.
Because using the technical solution of the utility model, the utility model is simple in construction, easily manufactured, by pad and
Anti- tilt nut structure is set to carry out nut between nut anti-oblique, even if drill body is not provided with nut groove and only set holding nut
Step, coordinated by the step for being in holding nut on its anterior other parts and drill body come location nut, also can be effective
Ground prevents that the phenomenon that clamping jaw drops occurs when clamping jaw from backing to the limit；Moreover, in the case of using anti-tilt nut structure, can enter
One step reduces the diameter of drill chuck drill body, in the case where drill body diameter is less than conventional minimum value, passes through the anti-tilt nut
Structure, can still ensure that nut center is vertical, in such manner, it is possible to reduce the weight of drill chuck, cost-effective, and and can reduce it is high
Shaking volume under speed rotation, improves drill chuck performance.

Embodiment
Embodiment 1, referring to the drawings 1,2,3.
Hand fastening drill clutch provided by the utility model, including drill body 1, nut 2, clamping jaw 3, the middle part of the drill body are set
Support level 11, pad 5 is placed on support level, and the drill chuck is provided with anti-tilt nut knot between nut and pad
Structure, when preventing that clamping jaw from backing to the limit, because of moment of torsion increase and imbalance, the axis of nut 2 is caused to tilt the axis of drill body
And clamping jaw is caused to drop.
Nut position-limited edge is set on the pad 5, the radial direction that position-limited edge is wrapped in the paired nut of nut profile is spacing, as
The anti-tilt nut structure.The stamped single piece for forming band edge 51 of the pad, the side 51 is used as nut position-limited edge.
The pad 5 is fixed on drill body by interference fit or clamping or other anti-rotation structures.
Drawing reference numeral 6 is the rotary sleeve in hand fastening drill clutch, and its internal step 61 in front of nut as with axially determining
The part of position nut, and then axial limiting position rotating covers 6 to the Forward End Cap 7 of drill chuck again.Rotary sleeve 6 and the keyway of nut 2 coordinate
Connection.Bearing of the drawing reference numeral 4 between nut and pad.
Embodiment 2, referring to the drawings 4,5.
In the present embodiment, the bottom of the nut 2 sets limited step or position-limited edge 21, the limited step and pad
5 coordinate, and the radial direction wrapped in the paired nut of the profile of pad 5 is spacing, as anti-tilt nut structure.
Limited step or position-limited edge 21 can be a parts for nut body, or be the part in nut sleeve.
Specific embodiment of the utility model is the foregoing is only, but architectural feature of the present utility model is not limited to
This, any those skilled in the art in the field of the invention, all cover of the present utility model by the change or modification made
Among protection domain.
