Detailed description of the invention
In order to make those skilled in the art be more fully understood that technical scheme, real with concrete below in conjunction with the accompanying drawings
The present invention is described in further detail to execute example.
As it is shown in figure 1, a kind of portable tightens fork spanner, including head 1 and shank 2, head 1 is provided with and can embed hexagonal spiral shell
The opening 9 (as shown in Figure 2) of female 10, opening 9 be sequentially provided with along clockwise direction the first flat clamping, the first spacing plane 5, the
Two spacing plane 7 and the second flat clamping 8；Wherein, the first flat clamping is parallel with the second flat clamping 8, the first flat clamping
With the angle that first between spacing plane 5 is 120 °, the angle between the first spacing plane 5 and the second spacing plane 7 is 120 °,
Angle between second spacing plane 7 and the second flat clamping 8 is 120 °.
The core of the present invention is that being provided with two is available for fork spanner in the premise not exiting, not loosening hex nut 10
Under, torsion counterclockwise just can complete the arc groove that fork spanner backlash resets.Concrete structure is as follows:
First flat clamping is made up of the first arc groove 3 of leading portion and the first flat clamping section 4 of back segment, the first circular arc
Groove 3 is close to opening 9；First spacing plane 5 is made up of the second arc groove 6 of the first of leading portion spacing section He back segment, and second
Arc groove 6 is close to the second spacing plane 7.The camber line of two arc grooves is minor arc, the center of circle of the first arc groove 3 correspondence
Angle can be 90 °, and the central angle of the second arc groove 6 correspondence can be 120 °.Wherein:
The parameter of the first arc groove 3 is: R1=0.35S, b1=0.65S.
The parameter of the first flat clamping section 4 is: h1=(0.25～0.3) S.
The parameter of the second arc groove 6 is: R2=0.25S, b2=0.6S.
The parameter of first spacing section is: h2=(0.3～0.4) S.
The degree of depth=the 1.2S of opening 9
Above-mentioned various in: the spacing of 10 two opposite side that are parallel to each other of S=hex nut；R1=it is the first arc groove 3
Radius；R2The radius of the=the second arc groove 6；b1The summit a of the=the first arc groove 31To the first flat clamping and the second folder
The distance of mid-plane m of tight plane 8；b2The summit a of the=the second arc groove 62Distance to opening center n；h1=the first folder
The length of tight planar section 4；h2The length of=the first spacing section.
During hex nut 10 embeds opening 9 for convenience, the forward terminal of the first arc groove 3 slightly can be raised.The most just
Being to say, the distance of the forward terminal of the first arc groove 3 to mid-plane m is more than the distance of aft terminal to mid-plane m.
In order to when fork spanner reverses counterclockwise, facilitate the rib of hex nut 10 to enter the second arc groove 6, therefore by second
Arc groove 6 is set to tangent with the second spacing plane 7.
In order to make fork spanner have a windup-degree when embedding hex nut 10 and tightening, therefore by the first flat clamping
It is set to 15 ° with the axis angle θ of handle.Due to the first flat clamping and the second flat clamping 8, thus the second flat clamping 8 with
The axis angle of handle is similarly 15 °.
The work process of the present invention is: as in figure 2 it is shown, embedded by hex nut 10 in the opening 9 of fork spanner, by the first folder
Tight planar section 4 and the second flat clamping 8 are by two opposing parallel flat grip of hex nut 10, and hex nut 10 phase
Two adjacent planes are limited the degree of depth entering opening 9 by the first spacing plane 5 and the second spacing plane 7.When fork spanner is clockwise
During torsion, as it is shown on figure 3, the first flat clamping section 4 and the second flat clamping 8 provide for hex nut 10 tightens required torsion
Power.When the extreme position that fork spanner turns to working place needs to reset, it is not necessary to opening 9 is backed off from hex nut 10,
Reverse counterclockwise.When fork spanner reverses counterclockwise, as shown in Figure 4, hex nut 10 is motionless, and on hex nut 10 with
First arc groove 3 and two ribs of the first flat clamping section 4 correspondence, can sequentially enter the first arc groove 3 and the second circular arc
Groove 6.The most just can realize fork spanner do not exiting.Rapid reset is completed, for next on the premise of not loosening hex nut 10
Secondary tighten ready.
The present invention reduces the action that repetition " is exited, is directed at and snaps in ", improve and tighten efficiency.
