Abstract
The utility model discloses a wrench steering arm. The wrench steering arm comprises a shell body and two shafts which extend out of the shell body. One ends, inside the shell body, of the two shafts are connected through a pair of bevel gears which are mutually meshed, and polygonal protruding blocks are arranged at the other ends of the two shafts along the direction of axis. The wrench steering arm can solve the steering problem of an existing wrench.
Description
Technical field
The utility model relates to the machine tool manufacture field, especially a kind of instrument for improving spanner and turning to.
Background technology
Spanner needs the handle of certain-length as the power moment of tightening nut, no matter be manual or electropneumatic spanner, all can only back-out or tighten operation to the nut bolt on rectilinear direction, perhaps spanner is along the axial tangential direction operation of nut bolt, perhaps operate along the nut bolt axis direction, like this, all must be at the axis of nut bolt or axially on the direction of tangent line, certain space is arranged, otherwise can't come the operating nut bolt with existing spanner.A kind of instrument that can provide spanner to turn to just is provided for this, to assist the nut bolt on the wrench operated vertical direction.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of spanner steering arm, can solve the Steering of existing spanner.
In order to address the above problem, the technical solution of the utility model is: this spanner steering arm include housing and from this housing stretch out two axles, described two axles connect by a pair of intermeshing bevel gear at an end of described enclosure interior, and the other end of described two axles is provided with polygonal projection along axis direction.
In technique scheme, more specifically scheme can be: wherein a described axle is provided with sleeve in the outside of described housing.
Further: described bevel gear is straight bevel gear.
Further: described polygon projection is square cylinder.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
Bevel gear and the axle that connect they the non-rectilinear transmission that realize power of this spanner steering arm by pair of meshing is to solve the Steering of spanner.
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the right view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:
This spanner steering arm as shown in Figure 1 and Figure 2, it comprises the formations such as housing 1, bevel gear 2, bearing 3, axle 4, sleeve 5.
This spanner steering arm has a housing 1, from interior extended orthogonal two axles 4 of this housing 1, housing 1 is provided with bearing 3 with axle 4 junctions, so that two axles 4 can rotate on the wall on the both sides of housing 1, and guarantees the stabilization that is connected between housing 1 and two axles 4; Two axles 4 connect by a pair of intermeshing bevel gear 2 at an end of housing 1 inside, and to realize the non-rectilinear transmission of power, the bevel gear 2 here is straight bevel gear.The other end of these two axles 4 is provided with polygonal projection along axis direction, and as the screens use that connects various bolts or sleeve, the polygon projection here is square cylinder.Wherein be set with sleeve 5 outside an axle 4, sleeve 5 can be used as handle and uses; The outer end of any one of two axles 4 all can connect various nut cutting ferrules, the outer sleeve 5 that is set with of another root axle 4, the outer end that this axle 4 of sleeve 5 is housed can connect electric-powered or pneumatic power, start electronic or pneumatic power, turning moment band dynamic bevel gear 2 rotates, and power direction is changed to vertical direction.Can select the sleeve 5 of different length equal-specification according to operating mode, to adapt to various operating modes, easy to use, flexible.
