Abstract

The utility model relates to a cross wrench for mounting nut usefulness, the special mounting tool of in particular to automobile tire. This cross wrench, package rubbing board pole and plate stem nut, characterized by still includes screw socket, the plate stem nut include big nut and little nut, the plate stem includes first plate stem and second plate stem, forms the plate stem nut behind the big nut of little nut emboitement, little nut can be for big nut coaxial rotation. Can slide each other between the plate stem of this product, for traditional fixed cross nut, 1.8 times can be enlargied to the moment of this product, have saved the material of instrument itself simultaneously, still can reach traditional fixed cross wrench's moment.

Description

A kind of cross like spanner

Technical field

The utility model relates to a kind of cross like spanner, for installing nut use, in particular to a kind of doughnut special installation tool.

Background technology

Often structure is simple for cross like spanner in existing market, cross like spanner is fixing dead often, can not relatively sliding, cause spanner cannot use in the place of some narrow spaces, also storage it is not easy to, in addition, traditional cross like spanner is the inreal maximum moment playing ejecting plate bar also, it may also be useful to person still needs could be turned by nut by bigger strength.

Practical novel content

The utility model object is to provide one can solve the above-mentioned problems in the prior art, and structure is simple, designs ingenious, the cross like spanner that can use flexibly.

The utility model object is achieved through the following technical solutions:

A kind of cross like spanner, comprises plate bar and plate bar nut, it is characterized in that, also comprising screw socket, described plate bar nut comprises big nut and primary nut, and plate bar comprises the first plate bar and the 2nd plate bar, composing plate bar nut after primary nut suit big nut, primary nut can relative to big nut coaxial rotation; Having plate bar square hole on big nut and primary nut, described plate bar is four square bars, and the first plate bar and the 2nd plate bar form cross after wearing big nut and primary nut respectively and pull bar; The end of the first plate bar and the 2nd plate bar is equipped with screw socket.

As preferably, described big nut is provided with interior flange, primary nut is provided with outer flange, the mutual sheathing that primary nut is matched by interior flange realize with big nut with outer flange.

As preferably, also including compression spring, add between interior flange and outer flange and join compression spring. Compression spring, by extruding big nut and primary nut, plays damping action for moving up and down of two plate bars so that have certain fixed action during rotary screw; In addition, it may also be useful to after completing, moreover it is possible to play the effect shrinking location, be convenient for carrying.

As preferably, the first described plate bar and the 2nd plate bar are slidably connected in plate bar square hole respectively.

As preferably, described big nut, primary nut, the first plate bar, the 2nd plate bar are metal.

As preferably, described big nut and primary nut are cylindrical tube shape.

As preferably, described plate bar square hole is square hole, four described square bars are square bar.

As preferably, described plate bar square hole is polygonal hole, four described square bars are the Polygons bar adapted with plate bar square hole.

Compared with prior art, this product compared with the existing technology has the following advantages and effect:

1, can mutually sliding between the plate bar of this product, relative to traditional fixed cross nut, the moment of this product can amplify 1.8 times.

2, the plate bar of product can 360 angles rotate arbitrarily, and plate bar slides up and down.

3, due to the increase of moment when product itself uses, the volume that this product can do is less, saves the material of instrument itself, still can reach the moment of traditional fixed cross like spanner simultaneously.

Label illustrates: the first plate bar 1, the 2nd plate bar 2, big nut 3, interior flange 31, primary nut 4, outer flange 41, plate bar square hole 5, four square bar 6, compression spring 7, screw socket 8.

Embodiment

Below in conjunction with specific embodiment, the utility model being described, the following example, only for illustration of the technical solution of the utility model, does not limit protection domain of the present utility model.

Embodiment one:

As Figure 1-4, the product of the present embodiment comprises plate bar, plate bar nut and screw socket 8, plate bar nut comprises big nut 3 and primary nut 4, big nut 3 and primary nut 4 are cylindrical tube shape, plate bar comprises the first plate bar 1 and the 2nd plate bar 2, primary nut 4 is set with the rear composing plate bar nut of big nut 3, and primary nut 4 can relative to big nut 3 coaxial rotation; Big nut 3 and primary nut 4 have plate bar square hole 5, plate bar is four square bars 6, first plate bar 1 and the 2nd plate bar 2 are worn big nut 3 respectively and are pulled bar with primary nut 4 rear composition cross, the end of the first plate bar 1 and the 2nd plate bar 2 is equipped with screw socket 8, and model is different, it is respectively 4 screw sockets 8 such as 17192123 grade, for doughnut is special. Big nut 3, primary nut 4, first plate bar 1, the 2nd plate bar 2 are metal, and plate bar square hole 5 wherein is square hole, four square bars 6 are square bar, in practical application, plate bar square hole 5 can also be polygonal hole, and four square bars 6 can also be the Polygons bar adapted with plate bar square hole 5, equally can technical solution problem.

The big nut 3 of the present embodiment is provided with interior flange 31, primary nut 4 is provided with outer flange 41, the mutual sheathing that primary nut 4 is matched by interior flange 31 realize with big nut 3 with outer flange 41, it may be achieved primary nut 4 can 360 angles coaxial relative to big nut 3 rotate arbitrarily.

The present embodiment also includes compression spring 7, adds and join compression spring 7 between interior flange 31 and outer flange 41. Compression spring 7, by extruding big nut 3 and primary nut 4, plays damping action for moving up and down of two plate bars so that have certain fixed action during rotary screw; In addition, it may also be useful to after completing, moreover it is possible to play the effect shrinking location, be convenient for carrying.

First plate bar 1 and the 2nd plate bar 2 of the present embodiment are slidably connected in plate bar square hole 5 respectively, can mutually slide between plate bar, and relative to traditional fixed cross nut, the moment of this product can amplify 1.8 times.

Due to the increase of moment when product itself uses, the volume that this product can do is less, saves the material of instrument itself, still can reach the moment of traditional fixed cross like spanner simultaneously.Several specific embodiments being only the application disclosed in above, but the application is not limited thereto, the changes that any person skilled in the art can think of, all should drop in the protection domain of the application.
