Description
Technical Field
The invention relates to the technical field of hand tools, in particular to a quick ratchet wheel hexagonal wrench.
Background
The hexagonal spanner in the existing market mostly comprises fixed spanner body, activity spanner mouth, helical gear etc. rotates through helical gear, screw-thread fit and adjusts, activity spanner mouth opening size carries out work, needs both hands operation in the use, and the adjustment helical gear of constantly rotating adjusts activity spanner mouth opening, consequently wastes time and energy relatively, and during the centre gripping work piece, the two-sided atress of monkey spanner is slipped easily, easily damages workpiece surface.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides the quick ratchet wheel hexagonal wrench which is reasonable in design, simple in structure, easy to manufacture and convenient to use.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a quick ratchet hexagonal spanner, by activity pull mouth, little round pin axle, little rivet, even piece, big round pin axle, torsional spring, big rivet, the button, fixed pulling body etc. constitute its characterized in that: the fixed body front end of pulling is equipped with fixed jaw, little rivet hole, big rivet hole and little round hole, the stalk portion of gripping is equipped with anti-skidding groove, fixed jaw's shape is outer arc gradually wound, the activity is pulled mouthful front end inboard and is equipped with 120 degrees V-arrangement face, the afterbody is equipped with little rivet hole and little round pin shaft hole and afterbody fluting, be equipped with big round pin shaft hole and big rivet hole on the button, the activity is pulled mouthful afterbody groove and is passed fixed pulling body and rivet through little rivet and little rivet hole through fixed pulling body, the activity is pulled the mouth and is passed through little round pin axle, link piece, big round pin axle and the big round pin shaft hole connection in button upper portion, the button lower extreme is pulled the body through big rivet and fixed, torsional spring coupling, torsional spring one.
The quick ratchet wheel hexagonal wrench is characterized in that: when the right upper end of the button is pressed by a hand, the button rotates clockwise around the large rivet to drive the connecting piece, the connecting piece drives the movable wrench opening, the movable wrench opening can rotate clockwise around the small rivet, the opening amount of the ratchet wheel hexagonal wrench is rapidly increased, and at the moment, the torsion spring is subjected to torsion bending and stores energy; when the ratchet wheel hexagonal wrench is sleeved on a workpiece, the torsion spring quickly releases energy only by loosening the hand, so that the movable wrench opening is driven to be quickly closed.
The quick ratchet wheel hexagonal wrench is characterized in that: the fixed body front end of pulling is equipped with fixed jaw, fixed jaw's shape is outer arc involute, the activity is pulled mouthful front end inboard and is equipped with 120 degrees V-arrangement face, when centre gripping hexagon nut, the activity is pulled mouthful V-arrangement face and hexagon nut's both ends face and is coincide completely, with the cooperation of fixed jaw's outer arc involute face, trilateral clamp is tight, the centre gripping is firm not skidded, clockwise rotation is screwed up the nut and when anticlockwise returning 60 degrees or 120 degrees, the activity is pulled mouthful and torsion spring cooperation self-holding, open, it has the ratchet function to screw up the nut repeatedly. The ratchet wheel clamping device has the advantages of reasonable design, simple structure, easiness in manufacturing, convenience in use and operation, time and labor conservation, capability of quickly clamping workpieces, ratchet function and great reduction of labor intensity of operators.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
FIG. 2 is a schematic view of the direction of force application.
The labels in the figure are: 1. the adjustable spanner comprises a movable spanner opening, 2 small pin shafts, 3 small rivets, 4 connecting pieces, 5 large pin shafts, 6 torsional springs, 7 large rivets, buttons, 9 and a fixed spanner body.
Detailed Description
As shown in fig. 1: the utility model provides a quick ratchet hexagonal spanner, is pulled mouthful 1, little round pin axle 2, little rivet 3, even piece 4, big round pin axle 5, torsional spring 6, big rivet 7 by the activity, and button 8, fixed pulling body 9 etc. constitute its characterized in that: the fixed 9 front ends of pulling the body are equipped with fixed jaw, little rivet hole, big rivet hole and little round hole, the stalk portion of gripping is equipped with anti-skidding groove, fixed jaw's shape is outer arc gradually wound, 1 front end inboard of mouth is pulled in the activity is equipped with 120 degrees V-arrangement face, the afterbody is equipped with little rivet hole and little round pin shaft hole and afterbody fluting, be equipped with big round pin shaft hole and big rivet hole on the button 8, 1 afterbody groove of mouth is pulled in the activity passes fixed pulling the body 9 and rivets through little rivet 3 and little rivet hole, mouth 4 is pulled in the activity through little round pin axle 2, link 4, big round pin axle 5 and the big round pin shaft hole connection in button 8 upper portion, 8 lower extremes of button pass through big rivet 7 and fixed pulling the body 9, 6 connections of torsional spring, 6 one end of torsional spring passes the little round.
The quick ratchet wheel hexagonal wrench is characterized in that: when the right upper end of the button 8 is pressed by a hand, the button 8 rotates clockwise around the large rivet to drive the connecting piece 4, the connecting piece 4 drives the movable wrench opening 1, the movable wrench opening 1 can rotate clockwise around the small rivet 3, the opening amount of the ratchet wheel hexagonal wrench is rapidly increased, and the torsion spring 6 is subjected to torsion bending and stores energy; after the ratchet wheel hexagonal wrench is sleeved on a workpiece, the torsion spring 6 releases energy rapidly only by loosening the hand, so that the movable wrench opening 1 is driven to close rapidly, rapid clamping is realized, and rapid loosening and operation are convenient.
The quick ratchet wheel hexagonal wrench is characterized in that: the fixed body 9 front end of pulling is equipped with fixed jaw, fixed jaw's shape is outer arc involute, the activity is pulled mouthful front end inboard and is equipped with 120 degrees V-arrangement faces, when centre gripping hexagon nut, the activity is pulled mouthful V-arrangement face and hexagon nut's both ends face and is coincide completely, with the cooperation of fixed jaw's outer arc involute face, trilateral clamp is tight, the centre gripping is firm not skidded, clockwise rotation is screwed up the nut and when anticlockwise returning 60 degrees or 120 degrees, mouth 1 and 6 cooperation self-holding of torsional spring are pulled in the activity, open, it has the ratchet function to screw up the nut repeatedly.
In conclusion, the ratchet wheel has the advantages of reasonable design, simple structure, easiness in manufacturing, convenience in use and operation, time and labor conservation, capability of rapidly clamping workpieces, ratchet function and great reduction of labor intensity of operators.
