Description
Technical field
The present invention relates to a kind of bolt collar, in design, describe inside and outside hex bolts sleeve in detail, be applicable to the internal-external hexagon bolt of different size.
Background technology
At present, known hex bolts sleeve function singleness, be man-to-man relation between sleeve and bolt, and a kind of sleeve can not apply to inside and outside hex bolts simultaneously.For convenience of using, people use sleeve set usually, not only quality is large for this, volume greatly, not portable, and the scattered easy loss of sleeve assembly, install change also cumbersome.
Summary of the invention
In order to overcome, existing hex bolts sleeve quality is large, volume greatly, not portable, sleeve assembly is easily lost and is installed and changes inconvenient deficiency, the invention provides a kind of variable bit chuck sleeve, this variable bit chuck sleeve is not only applicable to inside and outside hex bolts, and size can be regulated easily to adapt to the inside and outside hex bolts of different size.
The technical solution adopted for the present invention to solve the technical problems is: a kind of variable bit chuck sleeve, chuck, parcel, adjusting knob and handle are linked in sequence, each claw is respectively charged in 2-6 claw groove of chuck and (forms corner, hexagonal, anistree, ten jiaos and 12 corner bolt sleeves), it is characterized in that: parcel end-face helical engages with the claw tooth of claw end face, parcel end-face helical is equidistant involute screw thread, meet etc. the property entered and isometry, claw thread form shape is identical with the slot form of parcel end-face helical, claw tooth can slide in the teeth groove of parcel end-face helical, parcel rotarily drives claw along chuck radial motion, the parcel other end and adjusting knob meshing, parcel rotates together with adjusting knob, drive claw moving radially along chuck, it is meshing that the little axle head of handle passes adjusting knob and parcel centre bore and the little axle head of chuck, and handle rotates together with chuck.
Design for hex bolts sleeve: three claws are respectively charged in three claw grooves of chuck, the boss of claw side is positioned at the groove of claw groove side, make claw can only radially sliding along chuck, the claw tooth of each claw exposes the large end face of chuck, and the isosceles triangle two isosceles institute angle in claw upper clipping claw head cross section is outside chuck; Be inserted in by the little axle head of parcel upper end edge chuck, the flat thread of parcel end face is engaged with the claw tooth of claw end face, the rotation of parcel forces three claws to slide in the claw groove of chuck, and the boss of claw slides in the groove of claw groove; Adjusting knob is inserted in the little axle head of chuck, make the scalloped recess of adjusting knob end face and boss respectively with fan-shaped boss and the groove fit of parcel end face, rotation of adjustment knob impels parcel to rotate thus drives claw to radially move; The little axle head of handle is successively through adjusting knob and the centre bore of parcel and the little axle head of chuck, and by three to the fan-shaped boss of complementation and engagement, chuck is rotated together with handle capable of being and transmitting torque, during use, rotation adjusting knob makes claw clamping screw head.For the design of other corner, anise, ten jiaos and 12 corner bolt sleeves, change be the number of the claw groove of chuck and the specification (main manifestations is the size of isosceles triangle two waist angle) of claw head, do not change other structure.
Chuck little axle head center and the little axle head center of handle are by magnet attraction, and magnet is arranged in the cylindrical recesses that the little axle head of a chuck boss encloses, and makes chuck and Handle axis to adhesive.
Handle afterbody has horizontal assister bar.
Adjusting knob outer surface has annular knurl.
The claw sound of baby talk arc of claw end face is equidistant curve tooth, and parcel end-face helical is equidistant involute screw thread, and claw end surface is the isosceles triangle of drift angle 120 °, and the cross section circumference of dog group is regular hexagon, and inside enclosing profile is equilateral triangle.
The invention has the beneficial effects as follows: can turn adjusting knob easily, regulate the inside and outside of dog group to enclose overall size, the inside and outside profile of dog group applies to outer, the hexagon socket head cap screw of different size, many integration respectively, easy to adjust, laborsaving.
