Abstract

The utility model provides a multi-functional spanner of dismantling, it includes wrench body, set screw, the wrench arm, the cooperation wrench head, wrench body includes mutually perpendicular's center pin and handle, connect the center pin lower extreme and with center pin vertically connecting rod, when having solved and demolish special nut, ordinary spanner, box spanner can't use, must will connect the whole part of special nut and tear down, just can have sufficient space to demolish it, so take time, hard, and to the high precision part of assembly size requirement, probably because whole demolish and can't keep the problem of design accuracy, the efficiency of special nut dismantlement and the precision of assembly have been improved, the yields of product have been promoted.

Description

A kind of Multifunctional demountable spanner

Technical field

The present invention relates to a kind of spanner, more particularly to a kind of Multifunctional demountable spanner.

Background technology

With the continuous improvement of china's overall national strength, the science and technology of every field has all stepped into world-class level, its In in aviation field, manufacture field, have the nut of some special shapes, due to the limitation in shape and space, so commonly Spanner, box spanner are disassembled, reference picture 7, and the profile of special nut is irregular class hexagon, and is fixed on circle In the cavity of cylinder, to remove special nut, common wrench, box spanner cannot be used, it is necessary to will connect special nut whole Individual part is removed, and can just have enough spaces to be removed, so time-consuming, laborious, and for fitted position requirement Precise part high, probably due to overall pulling down and design accuracy cannot be kept, accordingly, it would be desirable to a kind of Multifunctional demountable is pulled Hand.

The content of the invention

It is an object of the invention to provide a kind of Multifunctional demountable spanner, when solving the special nut of dismounting, commonly pull Hand, box spanner cannot be used, it is necessary to will be connected special nut whole part and are removed, can just have enough spaces to be torn open Remove, it is so time-consuming, laborious, and for fitted position requirement precise part high, probably due to overall pulling down and cannot The problem of design accuracy is kept, the efficiency of special nut dismounting and the precision of assembling is improve, the yields of product is improved.

The present invention is achieved in that it includes wrench body, fixing screws, brace arm, cooperation driving end, and its feature exists In, wrench body include orthogonal central shaft and handle, connection central shaft lower end and with the connecting rod of central axis, even Extension bar is provided with several the second through holes for fixed handle arm, and connecting rod is provided with first leads to for insert brace arm Hole, is uniformly distributed the screwed hole of several threaded connection fixing screws on the brace arm, the brace arm lower end is fixedly connected There is the cooperation driving end for dismantling special nut.

Gap coordinates between the brace arm and first through hole.

It is described to coordinate driving end to be any one in class hex wrench head, the square driving end of class and class triangle driving end Kind.

The central shaft upper end is provided with the six-sided nut of connection ratchet spanner.

The solution have the advantages that：When solving the special nut of dismounting, common wrench, box spanner cannot be used, must Must will connect special nut whole part to remove, can just there are enough spaces to be removed, it is so time-consuming, laborious, and And for fitted position requirement precise part high, probably due to overall pulling down and the problem of design accuracy cannot be kept, improve The efficiency of special nut dismounting and the precision of assembling, improve the yields of product.

Specific embodiment

The present invention is described in detail below in conjunction with accompanying drawing embodiment to be had the advantage that, it is intended to which help is read

Reader more fully understands essence of the invention, but can not constitute any restriction to implementation of the invention and protection domain.

A kind of Multifunctional demountable spanner, it includes wrench body 1, fixing screws 2, brace arm 3, cooperation driving end 4, pulls Hand main body include orthogonal central shaft 13 and handle 14, connection central shaft lower end and with the connecting rod of central axis, even Extension bar is provided with several the second through holes 12 for fixed handle arm, connecting rod 15 be provided with for insert brace arm first Through hole 11, is uniformly distributed the screwed hole 31 of several threaded connection fixing screws on the brace arm, the brace arm lower end is consolidated Surely it is connected with the cooperation driving end for dismantling special nut 6.

Gap coordinates between the brace arm and first through hole.

The cooperation driving end is in the square driving end 42 of class hex wrench first 41, class and class triangle driving end 43 Any one.

The central shaft upper end is provided with the six-sided nut of connection ratchet spanner 5.

Using preceding, user selects brace arm 3 according to the appearance and size of special nut 6, when appearance and size and class hexagon The special nut 6 that driving end 41 is engaged, the brace arm 3 that will be fixedly connected with class hex wrench first 41 is fixed on connecting rod 15 On, and according to the position dimension of special nut 6, the level between connecting rod 15 and brace arm 3 is adjusted by fixing screws 2 Distance so that wrench body 1 has sufficient space to dismantle special nut 6；When appearance and size and class square driving end 42 is engaged Special nut 6, the brace arm 3 that will be fixedly connected with the square driving end 42 of class is fixed in connecting rod 15, and according to special spiral shell Female 6 position dimension, the horizontal range between connecting rod 15 and brace arm 3 is adjusted by fixing screws 2 so that wrench body 1 has sufficient space to dismantle special nut 6；When the special nut 6 that appearance and size is engaged with class triangle driving end 43, by fixation The brace arm 3 for being connected with class triangle driving end 43 is fixed in connecting rod 15, and according to the position dimension of special nut 6, The horizontal range between connecting rod 15 and brace arm 3 is adjusted by fixing screws 2 so that wrench body 1 has sufficient space to tear open Special nut 6 is unloaded, in above process, wrench body 1 upper end of central shaft 13 can be replaced with and is provided with connection ratchet spanner 5 The wrench body 1 of six-sided nut, so user can accelerate the speed of the special nut 6 of dismounting by ratchet spanner 5, by This, when we can show that the present invention solves dismounting special nut 6, common wrench, box spanner cannot be used, it is necessary to by even Connect the whole part of special nut 6 to remove, can just there are enough spaces to be removed, it is so time-consuming, laborious, and for Fitted position requirement precise part high, probably due to overall pulling down and the problem of design accuracy cannot be kept, it is special to improve The efficiency of the dismounting of nut 6 and the precision of assembling, improve the yields of product.

Embodiment described above is only that the preferred embodiment of the present invention is described, not to model of the invention Enclose and be defined, on the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art are to technical side of the invention Various modifications and improvement that case is made, all should fall into the protection domain of claims of the present invention determination.
