Description
Technical field
The present invention relates to relate to a kind of combination wrench.
Background technology
Spanner is to utilize lever principle to twist bolt, screw, nut and other screw threads tightly to hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner usually is shaped with clamp holder section and applies the external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut are held bolt or nut.Apply external force along the screw thread rotation direction at shank during use, just can twist bolt or nut.Spanner is divided into two kinds substantially, solid wrench and adjustable wrench, and solid wrench: one or both ends are shaped with the opening of fixed dimension, in order to nut or the bolt of twisting certain size.Adjustable wrench: A/F can be regulated in the certain size scope, can twist bolt or the nut of different size.But all there are certain shortcoming in solid wrench or adjustable wrench, and the solid wrench specification is too many, and each spanner can only be used for the screw of one or both models, and the scope of application is narrow; The convenience that adjustable wrench has a random adjustment but exists easily allows the existing picture of outer-hexagonal round end, and can not be used for hexagon socket head cap screw.
Summary of the invention
In order to address the deficiencies of the prior art, the object of the present invention is to provide a kind of combination wrench.
A kind of combination wrench comprises a disk, six identical screw rods and dop; Disk is circular column, and uniform six the hole hearts in the side of disk identical screwed hole on same plane, six identical screw rods place respectively in these six holes and can rotate advance and retreat, and then drive the dop advance and retreat;
One end band goat's horn of each screw rod, the other end is one section smooth round bar, and this smooth round bar one end has the convex positive stop ring, and there is the annular stop groove on the top;
Each dop comprises an exterior bayonet slot seat and an inner clip head seat; The exterior bayonet slot seat is the part of two different cuboid global formations of thickness, it is 120 ° V-type draw-in groove that one end of the cuboid of thin thickness has drift angle, six identical V-type draw-in grooves can be stuck in six angles of positive hex(agonal)screw head, tighten or unclamp screw by rotation; The screwed through hole of a horizontal direction is arranged at the top of the cuboid that thickness is thick, one end of screw rod passes this through hole, end face of exterior bayonet slot seat is spacing by the convex positive stop ring, another end face of exterior bayonet slot seat is by placing the limit spring pin in the limited impression spacing, guarantee that the exterior bayonet slot seat can not vertically move along screw rod 2, the smooth round bar of screw rod can rotate in through hole; The upper surface of the cuboid that the thickness of exterior bayonet slot seat is thick has one perpendicular to the screwed blind hole of upper surface,
The inner clip head seat is a cuboid, and the drift angle identical with thickness is the part of 60 ° regular triangular prism global formation; Be that 60 ° regular triangular prism top also has an inner clip head at drift angle, this inner clip head is to be superimposed upon this little quadrangular above regular triangular prism, and a drift angle of little quadrangular is 60 °, and another relative drift angle is 120 °; There is one on the cuboid of inner clip head seat perpendicular to the axis hole cuboid surface and that connect; With a top screw thread remainder being arranged is that the fastening bolt of polished rod places in the screwed blind hole of the axis hole of inner clip head seat and exterior bayonet slot seat, exterior bayonet slot seat and inner clip head seat are fixed, and, the inner clip head seat can be around described fastening bolt polished rod rotation, when its Rotate 180 °, 6 little quadrangulars can converge at the center, so that 120 ° of drift angles of the little quadrangular of inner clip head correct six angles of the groove that places interior positive hex(agonal)screw head, tighten or unclamp screw by rotation.
The use of a kind of combination wrench provided by the invention is dynamic:
(1) when being used for tightening or loosening the outer-hexagonal screw, be rotated counterclockwise six screw rods 2, six dops are separated from each other, when the space of six dops stops operating during greater than the hex(agonal)screw head; With combination wrench cover outside on the positive hex(agonal)screw head, more clockwise respectively right 2, six the identical V-type draw-in grooves 3 of two screw rods of rotating photo can be stuck in six angles of positive hex(agonal)screw head, then rotary disk 1 tightens or loosens hex(agonal)screw.
(2) when being used for tightening or loosening hexagon socket head cap screw, rotating six inner clip head seats 8 converges its direction towards the center of circle, six identical inner clip heads 4 can be inserted in the groove of interior positive hex(agonal)screw head, 120 ° of drift angles of the little quadrangular of inner clip head 4 correct six angles of the groove that places interior positive hex(agonal)screw head, tighten or unclamp screw by rotation.
Beneficial effect:A kind of combination wrench provided by the invention, it is by screw rod, and screw dish and dop form.Structural design is novel.Adopt six the goat's horn screw rods that can regulate to control dop.Be applicable to counter bore diameter greater than 4.7mm less than the screw of the interior positive bright mild steel hexagonal nuts of 15mm and nut circumscribed circle diameter greater than 5.7mm less than the fastening of the screw of the outer positive bright mild steel hexagonal nuts of 15mm with unclamp.Be convenient for carrying, not needing to change driving end just can complete operation, makes to unclamp or upper jack panel or screw rod become more time saving and energy saving.Have simple to operate and carry the advantage such as quick easy to assembly.
