Abstract
The utility model relates to a floating gear type movable wrench which is mainly characterized in that a swinging rack is arranged on a wrench head, a floating gear is arranged between the swinging rack and a movable jaw, and the adoption of the transmission of the floating gear and the rack can change a meshed clearance between the rack and the floating gear so as to realize locking or releasing of an opening of the wrench by changing the position of the swinging rack. The floating gear type adjustable wrench can realize the continuous free pulling like a socket wrench of the existing ratchet wheel.
Description
Technical field:
The utility model relates to a kind of monkey wrench, particularly a kind of floating gear formula monkey wrench.
Background technology:
Monkey wrench is a kind of common power tool, and the dismounting of securing member usually will be used it.Because monkey wrench can be fit to the dismounting of the securing member of plurality of specifications in the scope of certain size, thus have more convenience, flexibility than Open jaw type wrench, box spanner, the monkey wrench utilization of now continuing to use be the transmission and the auto-lock function of screw thread.The location of wrench opening realizes by regulating manually, because the wrench opening card gets tightly inadequately, is easy to cause and skids in the middle of practical operation, and the turret head of nut is pulled back round end.Spanner inserts releasing after nut switching one angle in use again and continues next action on the other hand, can not resemble box spanner cooperate ratchet wrench fast work continuously freely.
Summary of the invention:
The purpose of this utility model is to adopt the transmission of wheel and rack to realize any wrench opening location, utilizes the fit clearance that changes between swing tooth bar and floating gear to realize self-locking and a kind of floating gear formula monkey wrench of designing.
The purpose of this utility model is achieved in that a kind of floating gear formula monkey wrench, has spanner handle, driving end, movable jaw, it is characterized in that: be provided with secondary handle by roller pin and spring on spanner handle; On driving end, be provided with the swing tooth bar by swivel pin; On movable jaw, be provided with stationary rack, on the driving end above the movable jaw, be provided with extension spring; Being provided with floating gear between the swing tooth bar on movable jaw stationary rack and the driving end is meshed with it; One of described secondary handle is cam, and its cam contacts with the swing tooth bar; Described driving end and movable jaw front end are provided with the little opening of 120 ° of angles.
The worm drive that the utility model utilizes tooth bar transmission replacement to continue to use for many years make the structure of monkey wrench that the change of essence arranged.Down auxiliary at flexible member with Telescopic, because design has a angle 120 ° little opening between the upper jaw and the lower jaw of spanner front end, therefore people pick up this spanner and just can directly insert facing to the trigonocephalia of nut, need not to do any action again, just can make and pull mouthful automatic a location.Under the cooperation of the secondary handle with leverage, wrench opening can be realized the self-locking of floating gear at any time and get loose.After nut was pulled an angle, spanner need not to extract out like this, and reverse switching one angle can repeat last action, realized resembling ratchet wrench and moved continuously freely the box spanner under cooperating.
Description of drawings:
Fig. 1 is the utility model structural representation.
Among the figure: 1, spanner handle; 2, secondary handle; 3, floating gear; 4, driving end; 5, swivel pin; 6, swing tooth bar; 7, extension spring; 8, alignment pin; 9, the movable jaw of band stationary rack; 10, roller pin; 11, spring.
The specific embodiment:
As shown in Figure 1, the utility model is made up of movable jaw 9, roller pin 10, the spring 11 of spanner handle 1, secondary handle 2, floating gear 3, driving end 4, swivel pin 5, swing tooth bar 6, extension spring 7, alignment pin 8, band stationary rack.The utility model from outside watch with used monkey wrench and do not have great difference.The fixed jaw that joins together with driving end fully with now use monkey wrench consistent.And promptly having replaced it with the profile of tooth of tooth bar, movable jaw plays the screw thread of gearing.Equipped one spring or the rubber strip with Telescopic behind the penetrating hole of centre drill of the sliding shoe of its circular arc, its upper and lower side is all fixed with movable jaw, and this can not be come off.Spanner is the time spent not, and under the effect of flexible member, opening is closed.Because fixing front end with movable jaw is provided with the breach of 120 ° of angles, when people advanced spanner facing to six corners outside the nut when, flexible member was elongated and makes movable jaw can locate the opposite side of binding nut under the effect of pulling force under any position during use.In wrench opening, do down motion by the rack drives floating gear of movable jaw.The tooth bar on floating gear right side is because the upper end is hinged bearing pin and fixes, and it can only swing and can not move up and down, and operating in up and down on the swing tooth bar of floating gear promptly creeped up and down.Behind the wrench opening location, be that floating gear arrives minimum point, at this moment people's secondary handle of holding with a firm grip, making push rod move and press closer the swing tooth bar to the right by a leverage moves to the left, at this moment left and right sides tooth bar has been formed a wedged gap and the floating gear of centre tightly has been locked in arbitrary position by parallel, and spanner just can have been pulled nut.After nut was pulled certain angle, unclamp secondary handle, push rod is under spring action, and automatically reseting makes the swing tooth bar also return to original position.At this moment, people can not will spanner extract out, unclamp the reverse handle that lifts behind the secondary handle, because the diagonal-size of nut is greater than opposite side, when lifting handle, the opening of spanner can overcome the tight power of flexible member and slide and open, slided moment behind the diagonal angle of nut is promptly clamped the opposite side of nut again, the secondary handle of holding with a firm grip again can repeat last action, realizes resembling the pulling freely continuously the box spanner of ratchet.The operating principle of floating gear spanner in sum, the opening location is located by the elastic stretching element, the locking of opening decides with the swing that gets loose by the operation lower swing tooth bar of secondary handle, folded gear is constantly to fluctuate all the time between the tooth bar of the left and right sides in whole use, also be this spanner name its say reason place into the floating gear spanner.
