Embodiment
Referring to the drawings.Hand fastening drill clutch provided by the utility model includes drill body 1, nut 2, clamping jaw 3.The drill body
Middle part sets support level 11, packing ring 4 is placed on support level 11, the packing ring 4 is the packing ring of holding nut 2, in 2 He of nut
Lubricating structure, such as bearing 5 can be set between packing ring 4, the packing ring is fixedly connected and relatively unrotatable with drill body 1, such as
Connected using interference fit.
The hand fastening drill clutch is equipped with inclined clamping jaw hole 6, and clamping jaw 3 is threaded through in clamping jaw hole 6, and clamping jaw 3 has external screw thread
And be threadedly coupled with nut 2, moved forward and backward by driving of the nut 2 to it, to clamp and loosen drill bit.The clamping jaw hole 6
It is formed on the composite entity part of the packing ring 4 and drill body 1, during fabrication, first packing ring is sleeved on drill body and shifts branch onto always
On support step 11 and interference fit is formed, inclined clamping jaw then is processed to packing ring 4 and 1 composite entity part drill bit 100 of drill body
Hole 6, also has the partial contour wall 40 in clamping jaw hole 6 on the packing ring 4 at the position that clamping jaw passes through, partial contour wall 40 with it
Portion jaws hole wall 60 on the drill body of inner side synthesizes clamping jaw hole profile on the position, the clamping jaw hole wheel on the packing ring 4
Wide wall 40 is in the skew wall along clamping jaw hole gradient.
The drill chuck is provided with anti-tilt nut structure between nuts and washers, when preventing that clamping jaw from backing to the limit,
Because of moment of torsion increase and imbalance, the central axes of nut 2 are caused to tilt the central axes of drill body and cause clamping jaw to drop.
