Abstract
The utility model discloses a universal adjustable wrench, which changes the opening adjustment through an adjusting wheel of the original adjustable wrench into the adjustment through the compression of a spring. The wrench comprises a fixed jaw, a movable jaw and an antagonistic spring. The fixed jaw and the movable jaw are hinged; and the antagonistic spring which is connected with the fixed jaw is arranged at the front side of the movable jaw. In another proposal, besides the parts, a movable jaw supporting handle is additionally arranged and an antagonistic spring is also arranged on the front side thereof. Under normal torque, the proposal I can meet the requirements, and the proposal II can meet the use requirements under large torque. The movable jaw supporting handle in the proposal II aims at preventing the movable jaw from being sliding off under large torque and pressing the movable jaw when screwing a nut; when the jaw is opened, the handle has to be manually pressed. The universal adjustable wrench overcomes the defects of loosening and skidding of common movable wrenches and has the advantages of convenient use, safety and reliability, broad prospect and large application range; moreover, the universal adjustable wrench is suitable for families as well as industrial and mining establishments to assemble bolts and pipe fittings.
Description
Technical field
The utility model patent relates to a kind of common tool monkey wrench, particularly a kind of omnipotent monkey wrench.
Background technology
Existing monkey wrench is to be made up of regulating wheel, regular jaw and adjustable jaw three parts.The sizes that adopt regulating wheel to regulate wrench opening are prone to the spanner regulating wheel and become flexible more during use, cause skidding during clamp nut, bring inconvenience to the user.
Summary of the invention
The utility model provides a kind of simple in structure in order to overcome the defective of prior art, and easy to use, safe and reliable omnipotent monkey wrench has saved regulating wheel, has avoided loosening because of regulating wheel, causes skidding during clamp nut.
The utility model has adopted following technical scheme to realize:
The utility model system regulates the regulating wheel of wrench opening and changes the spring press-type into.
This omnipotent monkey wrench comprises regular jaw, moving jaw and antagonistic spring.
The two hinge of regular jaw and moving jaw is connected, and the moving jaw front side is provided with antagonistic spring.Having only moving jaw and regular jaw to be combined together just can use, moving jaw is opened during use, allow folder enter between regular jaw and the moving jaw, the long handle that grasps regular jaw spurs handle clockwise, at this moment fixed handle and moving jaw will tightly be fixed folder, when firmly spurring fixed handle and turning clockwise, folder also can rotate along with fixed handle is subjected to force direction.Fixed handle and flexible handle are supporting uses, present the effect of active force and reaction force.
The utility model also can be realized by the following technical solutions:
This omnipotent monkey wrench comprises regular jaw, moving jaw, antagonistic spring, moving jaw support handle and antagonistic spring.
The two hinge of regular jaw and moving jaw is connected, and the moving jaw front side is provided with antagonistic spring, and the moving jaw support handle is set separately, also is provided with antagonistic spring in its front side.Having only moving jaw and regular jaw to be combined together just can use, press the support handle of moving jaw during use, allow moving jaw open, allow folder enter between regular jaw and the moving jaw, unclamp the support handle of moving jaw, the long handle that grasps regular jaw spurs handle clockwise, at this moment fixed handle and moving jaw will be only folder is fixed tightly, when firmly spurring fixed handle and turning clockwise, folder also can rotate along with fixed handle is subjected to force direction.Fixed handle and flexible handle are supporting uses, present the effect of active force and reaction force, and the support handle of moving jaw plays the effect of supporting moving jaw and moving jaw being pressurizeed.
Scheme two is many a reaction force spring and moving jaw support handles on the basis of scheme one, and under general moment, scheme is once satisfying the demand.Scheme two can satisfy under big moment to be used.Monkey wrench support handle in the scheme two plays the effect of pressurization moving jaw in order to prevent moving jaw when big moment downslide is taken off with nutting, when opening jaw, manually press this handle.
The use of spanner and force analysis: the opening portion of spanner is that moving jaw is longer than regular jaw, when the card nut, grow part with this and withstand nut, hand is pressed the moving jaw support handle and is promoted monkey wrench forward, moving jaw is opened, allow screw enter between moving jaw and the regular jaw, when spanner blocks nut, antagonistic spring therefore and stressed, what spanner can be with the nut card like this is tighter, after spanner tightens, turn clockwise fastening nut (in scheme two, have two antagonistic springs and simultaneously moving jaw exerted pressure, can carry out big torque operation like this), during nutting, being subjected to force direction is that clockwise arc is identical with the direction of wrench opening part clamp nut, the power of nutting is big more, and the pressure that nut is subjected to is just big more, and nut just blocks tightly more.After nut is tightened to the position, in scheme one, can easily withdraw from spanner.But in scheme two, must to the monkey wrench support handle apply external force just with hand by the lower ejector lever support handle, can easily withdraw from spanner, in brief, scheme two than scheme more than individual moving jaw support handle, the moving jaw support handle is fixing dead with moving jaw during use, must press the moving jaw support handle, and moving jaw is opened just can be used.
Omnipotent monkey wrench has overcome the drawback that the general activity spanner becomes flexible, skids, and this spanner is esy to use, safe and reliable, is applicable to the bolt and the pipe fitting assembling of family, industrial and mining enterprises, has a extensive future, and the scope of application is big.
