Between spacing spacing adjustment bindiny mechanism；The spacing adjustment bindiny mechanism include guide, Flexible Connector, adjustment part and
Promote the pushing mechanism of adjustment part motion；Wherein：
The adjacent end face of described upper pedal arm 1, upper pedal arm 2 is set to off in symmetry axis a8 symmetrical end slant surface；
Described guide, the opposite or opposite motion to upper pedal arm 1, lower pedal arm 3 provides guiding, described in accompanying drawing
Guide be a fairlead 6, one end of fairlead has the side slidable connection of end slant surface with upper pedal arm, is oriented to
The other end of set then has the side slidable connection of end slant surface with lower pedal arm；Certainly, guide of the present invention
Be not limited to the fairlead described in accompanying drawing, as long as in fact, its can to upper pedal arm 1, lower pedal arm 3 opposite or
Opposite motion is provided and is oriented to；Certainly, the present invention using fairlead purpose, also with adjustment part and adjustment part are distinguished
The effect encapsulated with upper pedal arm 1, the connecting portion of lower pedal arm 3.
Described adjustment part, is placed between upper pedal arm and lower pedal arm, for adjust upper pedal arm and lower pedal arm it
Between spacing, and support is attached with lower pedal arm to upper pedal arm；Under the start of pushing mechanism, can be transported along symmetry axis a21
It is dynamic；With two drive divisions, respectively start in drive division a, the start of upper pedal arm end slant surface in lower pedal arm end
The drive division b22 of inclined plane；In accompanying drawing 2,3, the wedge-shaped block structure that described adjustment part is used, therefore, the wedge necessarily has
There is the lozenges that end slant surface respectively with upper pedal arm, the end slant surface of lower pedal arm are adapted, to be correspondingly formed
Drive division a21, drive division b22；Certainly, adjustment part of the present invention is not limited to the wedge-shaped block structure referred in accompanying drawing,
In fact, it only needs to be that the end slant surface with end slant surface respectively with upper pedal arm, lower pedal arm is adapted
The part of lozenges, certainly, it can not even use lozenges as drive surface, and it can be continuous using physical dimension
The axial symmetry part of gradual change, such as the periphery of cone, spheroid etc. as drive surface, simply this structure for upper pedal arm with
For connection support between lower pedal arm, weaken.
Described pushing mechanism, for promoting adjustment part to be moved along symmetry axis a；Including catch bar and locking member；Push away
Lever one end is located at fairlead outside, the other end then through after fairlead, with adjustment part medium position at the notch that sets compress,
And connection is oriented between catch bar and fairlead；Locking member nestles up fairlead outer wall on the body of rod of catch bar.Accompanying drawing
In, described catch bar is stud, and locking member is locking nut；One end of stud through after fairlead with adjustment part medium position
The notch 23 for locating to set is compressed, spacing to carry out to stud, and screw thread is connected between stud and fairlead, and locking nut is matched somebody with somebody
On stud, and positioned at the outside of fairlead.
Described Flexible Connector, for connecting upper pedal arm 1, lower pedal arm 3 so that upper pedal arm 1, adjustment part, under
Pedal arm 3 is mutually compressed, and is assembled into a complete pedal arm being connected with pedal.In accompanying drawing, described Flexible Connector is
Extension spring, including two, set up separately in the both sides of pedal arm, and positioned at the outside of fairlead；Each two ends of extension spring respectively with
Upper pedal arm, lower pedal arm correspondence are connected.Draw ring a snappings on each one end of extension spring and upper pedal arm, the other end is with
Draw ring b snappings on pedal arm.
When adjustment part is moved along symmetry axis a, adjustment part can be by drive division a to the sloped-end of upper pedal arm
Face, drive division b apply to drive to the end slant surface of lower pedal arm, promote the upper pedal arm, lower pedal arm can be along guide
The guide direction of offer is opposite or slide in opposition, and the restoring force that Flexible Connector is provided, it can be ensured that the end of upper pedal arm
Portion's inclined plane is compressed all the time with the drive division b of the drive division a, the end slant surface of lower pedal arm and adjustment part of adjustment part.
Operation principle of the invention is：
When need to amplify gearratio, locking nut 4 is unscrewed first, to screw-in stud 5, work of the wedge 2 in stud 5 in fairlead 6
Push away upper pedal arm 1 and lower pedal arm 3 to both sides with lower, screwed after the completion of adjustment locking nut 4 carry out it is locking；Dynamic ratio need to be reduced
When, hex nut 4 is unscrewed first, to stud 5 is screwed out outside fairlead 6, upper pedal arm 1 and lower pedal arm 3 are tensing the effect of spring 7
Lower compression wedge 2 makes to move thereon, upper pedal arm 1 and the lower distance of pedal arm 3 further realize pedal drive than diminution；Adjust
Screwed after hex nut 4 carry out it is locking.
