Embodiment
Referring to the drawings.Hand fastening drill clutch provided by the present invention, including drill body 1, nut 40, clamping jaw 5, setting and nut 40
The first axial tooth 41 in the collar member 4 being fixedly connected, the collar member 4 is preferably nut sleeve, and the hand fastening drill clutch is additionally provided with
Second axial tooth 23 is set in the lifters 2 that can not be rotated but can axially lift relative to drill body 1, the lifters 2, it is described hand-tight
Drill chuck is provided with the elevating mechanism of lifters 2, enable second axial tooth 23 engaged with first axial tooth 41 and
Depart from, the hand fastening drill clutch is provided with the functional unit of the elevating mechanism.The axial tooth 41,23 can also be replaced by key
Generation, or other fastener necks are substituted.
The lifters are arranged on the front of the nut 40, and the lifters 2 are preferably annular element, and lifters 2 are enclosed on
Outside drill body 1, coordinated by the plane 22 on the inside of it and the plane 11 of drill body 1, prevent lifters 2 from rotating.
The hand fastening drill clutch is provided with overcoat 7 in the front of nut 40, as the functional unit, so more meets people
Body engineering, operation more facilitates.
The elevating mechanism includes spring 8 and control collar member 3, and the lifters 2 are provided with concavo-convex platform 20 and mounting cylinder
Portion 21, the concavo-convex platform 20 and control collar member 3 formation cam mechanism control coordinate, and by the cam mechanism control coordinate and
The spring 8 drives lifters 2 to be advanced axially relative and retreat.The cam mechanism includes being in the portion of the concavo-convex lower surface of platform 20
Divide 24 and the part 33 being in control collar member 3.
Second axial tooth 23 can be a sun gear member, first by the mounting cylinder for controlling collar member 3 to be inserted in lifters 2
Sun gear member, is then mounted in the end in mounting cylinder portion 21 by portion 21.
Control collar member 3 itself can also be used as the functional unit, it is preferable that the control collar member 3 is rotatable collar member,
The overcoat 7 and control collar member 3 are connected, by overcoat 7 come operational control collar member 3.The hand fastening drill clutch is provided with the control
The position limiting structure of the rotational angle range of collar member 3 processed.The position limiting structure can be in control collar member 3 and drill body 1 between or and
With drill body 1 between relatively unrotatable part, in the present embodiment, the position limiting structure is by being arranged in control collar member 3
Groove 34 and the key 25 being in lifters 2 are constituted.
The spring 8 is in the front of the concavo-convex platform 20, and the control collar member 3 is in the rear of the concavo-convex platform 20.
