Spine tooth 35 coordinates to be fixed with described stepping sheet 2, and described stepping sheet 2 is simultaneously fixed at again on fixed mount 1, the most described upper connecting rod
One end of 51 is erected on the boss of described fixture 6, and therefore, upper connecting rod 51 and lower connecting rod 52 are fixing relative to described
Frame 1 and fixture 6 are fixed, and therefore tetragon component 100 presents overall stationary state.Now, described fixed mount 1 is additionally provided with one
Individual spike, this stepping quick access device and electric traction head 7 combine its steering wheel 76 and i.e. can be placed on ground.
Take out described Rear frame 8, its sleeve pipe 83 is socketed in described connecting rod 14, described perforation 84 and described through hole 15
Alignment.Now Rear frame 8 is static with described stepping quick access device but do not fasten.
When, after the button 32 pressing described handle 3, button 32 promotes described plectrum 31, plectrum by the linkage of described steel wire 33
The spine tooth 35 of 31 is i.e. deviate from from the ratchet 20 of described stepping sheet 2, counterclockwise pulls handle 3 by figure.Due to spine tooth 35
Can stop in the middle of any one tooth of ratchet 20, be consequently belonging to stepping and pull.
Owing to the stress surface 42 of drive block 4 is adjacent to described handle 3 all the time, so when counter clockwise direction in figure pressed by handle 3
During rotation, described drive block 4 also can be driven rotate in an anti-clockwise direction.Now, described round pin by drive block 4 drive also cross
Described perforation 84 is fixed with described through hole 15 and then by described Rear frame 8 with fixed mount 1.At this moment, Rear frame 8 and electric traction head
7 are i.e. fixed together by stepping quick access device.
Further, the most as shown in Figure 8, due to rotating counterclockwise of handle 3, make the 3rd pivoting point 34 also can be counterclockwise
Rotate, i.e. drive support bar 10 to move, place due to the steering wheel 76 of electric traction head 7 and be in described trailing wheel 82 on the ground
In same level and will not move up and down, then the horizontal plane at universal wheel 81 place of Rear frame 8 i.e. can be higher than described steering wheel
76 and trailing wheel 82 place horizontal plane.So, the universal wheel 81 of Electric disability vehicle will not hinder driving.
When needs use common hand wheelchair, press the button 32 of lower handle 3, and by this handle 3 side clockwise along figure
To rotation, now drive block 4 resets under the effect of reduction torsion spring 41, and round pin resets under the effect of spring 91.Thus
Can be pulled away from described connecting rod 14 by sleeve pipe 83, such Rear frame 8 i.e. separates with electric traction head 7, general as Rear frame 8
Logical hand wheelchair can be used by common hand wheelchair.
Except the Electric disability vehicle in above-described embodiment, in other embodiments, described stepping quick access device can also connect
The Rear frame connecing ordinary bicycle forms ordinary bicycle, or can also connect the Rear frame of common electric car, thus becomes
Common electric motor car with two wheels etc., as long as Rear frame includes that the sleeve pipe 83 being connected with stepping quick access device gets final product and this utility model
Stepping quick access device connect formed need product or structure.This utility model still has numerous embodiments, and all employings are equal to
Conversion or equivalent transformation and all technical schemes of being formed, within all falling within protection domain of the present utility model.
