Abstract

The utility model discloses an adjusting wrench, which comprises a fastening wheel disc, wherein a plurality of movable clamping heads are arranged in the fastening wheel disc, the movable clamping heads in the fastening wheel disc are not fixed with one another, each movable clamping head is provided with an independent sliding rod, the sliding rod is arranged in a corresponding groove on a gear disc, the movable clamping heads simultaneously and equally slides towards the same direction in the sliding grooves to achieve the purpose of adjusting the size of a nut clamping head, the gear disc is arranged in the fastening wheel disc, teeth at edges of the gear disc deviates towards the same direction, the fastening wheel disc comprises a wheel disc shell, the wheel disc shell is mainly used for protecting the gear disc and fixing direction, a clamping hook is arranged on the wheel disc shell, the inner side of the clamping hook is propped up by a device like a spring, so that the gear disc can be tightly hooked by the clamping hook under no external force and is prevented from reversely rotating. Since the teeth of the gear disc deviates towards the same direction, the gear disc can be controlled to unidirectionally rotate to make the nut clamping head tightened, and the purpose of tightly gripping a nut is achieved; when pressed, the clamping hook loosens the gear disc, and the gear disc can reversely rotate so as to make the nut clamping head large to loosen the nut; and the fastening wheel disc serves as an independent part of the adjusting wrench, different models can be disassembled, assembled and replaced, and the adjusting wrench can be adapted to nuts at different angles.

Description

Regulate the metal plate hand

Technical field

The utility model relates to screw. screw. and rotation type office. the handling instrument of utensils such as dop especially relates to the loading and unloading that are inscribed within round angle class screw.

Background technology

At present, the existing screw that uses in social life is no matter be triangle. four jiaos. and five jiaos or hex screw; According to the difference of the shape need and the bearing strength of module, different variations is also taking place in the specification of these screws and profile, and this has also caused the metal plate palmistry correspondence of a certain model of screw needs of each specification; Just can operate, people can be for the demand under the emergency case, and standing a large amount of metal plate hand is operated for you to choose; This has also caused a lot of inconvenience, and also having part to regulate a type metal plate hand at present can carry out parallel clamping to hex screw, thereby carries out charge and discharge operations; But the limitation that such metal plate hand uses makes it can not be useful for the screw that does not have two parallel edges; And such metal plate hand is bigger to the wearing and tearing of screw, usually damages screw cap, brings more how unnecessary trouble.

Summary of the invention

The purpose of the utility model is in order to solve that angle class screw is inconvenient to load and unload and a kind of scalable metal plate hand capable of being combined that is useful for big measuring angle class screw of designing.

The utility model realizes regulating the technical scheme that is adopted on its technical purpose ground of metal plate hand: described adjusting metal plate hand comprises fastening wheel disc, is provided with a plurality of cap nut dops in the said fastening wheel disc, and is unfixing between a plurality of cap nut dops in the said fastening wheel disc; Each cap nut dop has its independently slide bar, and slide bar is by in the corresponding chute of device on toothed disc, and the cap nut dop relies on the purpose that reaches set screw cap dop size simultaneously with amount slip in chute in the same way; Be provided with a toothed disc in the described fastening wheel disc, the same direction of the full deflection of the tooth at toothed disc edge, said fastening wheel disc comprises a wheel disc shell; The effect of wheel disc shell is mainly used in protection toothed disc and fixed-direction, and the wheel disc shell is provided with a grab, is upspring it by the spring-like device in the inboard of grab; Make grab outside not having, can tightly hook toothed disc in the active force and prevent that its reverse revolving from enclosing; Because the tooth of toothed disc is partial to same direction,, reach the purpose of tightly stinging cap nut so it can the unidirectional rotation of control gear dish become tight with the cap nut dop; When grab is pressed; Grab is decontroled toothed disc, thereby toothed disc just can counter-rotating unclamp cap nut with the amplification of cap nut dop, and fastening wheel disc is as the individual components of regulating the metal plate hand; Can load and unload the replacing different model, adapt to the cap nut of different angles.

Described adjusting metal plate hand comprises the one-way rocker dish.The one-way rocker dish is made up of ratchet dish and rocking bar; Is made up of toothed disc grab and spring-like device in the ratchet dish, the tooth at toothed disc edge is partial to same direction entirely, and grab can tightly hook toothed disc and prevent that its reverse revolving from enclosing in this structure in the active force outside nothing; The spring-like device can be in the extruding contraction down of gear tooth when the disc spins; Thereby grab allows gear along disc spins, and grab can hook gear against disc spins the time, prevents that tool from reversing; The purpose of one-way rocker dish is need not the metal plate hand be carried out 360 degree rotations when letting operation metal plate hand person operate; Get final product complete operation and only need not stop waggle at any angle, the tow sides of one-way rocker dish all can install connecting rod, and tow sides just in time correspondence turn clockwise and revolve counterclockwise.

Described adjusting metal plate hand comprises connecting rod.Connecting rod is mainly used in fastening wheel disc and one-way rocker dish is coupled together; Why connecting rod effect individual part is made up use; Be because the nut of part screw over head and ears in the screw hole, need extend fastening wheel disc in the screw hole and operate, can't operate if connecting rod is too short; Screw cap exposes does not then need long connecting rod, selects to use so connecting rod is mainly looked the depth of screw hole.

As preferably, the length of described adjusting metal plate hand scalable connecting rod adapts to the working environment under the varying environment, for example gets deeply stuck in the screw of screw hole, the screw that activity space is little etc.

As preferably, thereby the fastening wheel disc of described adjusting metal plate hand scalable adapts to the screw cap of different model, and multi-angle tightly stings and can protect screw cap can not damage because of multi-pass operation, prolongs the service life of screw and metal plate hand.

As preferably, thereby the replaceable fastening wheel disc of described adjusting metal plate hand is useful for the screw of different angles, triangle for example, quadrangle, pentagon, hexagon etc.

As preferably, do not need again whole metal plate hand to be carried out 360 during described adjusting metal plate hand operated and rotated, the adjustment angle that does not also need not stop has been operated, and fixing back only need swing back and forth at any angle and get final product.
