Preferred structure in example is applied, the electric traction head 7 can also be the electric truck head part of known any front-wheel drive
Structure.
It is specific when being assembled using the stepping quick access device progress electric traction head 7 and hand wheelchair 8 of the present invention
Process is as follows：
When original state, whole stationary state is presented in the quadrangle component 100, i.e., the described handle 3 passes through 20 He of ratchet
Spine tooth 35 coordinates to be fixed with the stepping piece 2, and the stepping piece 2 is fixed on fixed frame 1 simultaneously again, in addition the upper connecting rod
51 one end is erected on the boss of the fixing piece 6, and therefore, upper connecting rod 51 and lower connecting rod 52 are relative to the fixation
Frame 1 and fixing piece 6 are fixed, therefore whole stationary state is presented in quadrangle component 100.At this point, being additionally provided with one on the fixed frame 1
A spike, the stepping quick access device and electric traction head 7 combine its steering wheel 76 to can be placed on ground.
The Rear frame 8 is taken out, its casing 83 is socketed in the connecting rod 14, the perforation 84 and the through-hole 15
Alignment.Rear frame 8 is static with the stepping quick access device at this time but does not fasten.
After pressing button 32 of the handle 3, button 32 pushes the plectrum 31, plectrum by the linkage of the steel wire 33
31 spine tooth 35 is deviate from from the ratchet 20 of the stepping piece 2, by counterclockwise pulling handle 3 in figure.Due to spine tooth 35
It can be stopped among any one tooth of ratchet 20, be consequently belonging to stepping pulling.
Since the stress surface 42 of drive block 4 is adjacent to the handle 3 always, so when handle 3 is by counter clockwise direction in figure
When rotation, the drive block 4 can also be rotated in an anti-clockwise direction by driving.At this point, the round pin by drive block 4 drive also cross
The perforation 84 is fixed with the through-hole 15 and then by the Rear frame 8 and fixed frame 1.At this moment, Rear frame 8 and electric traction head
7 are fixed together by stepping quick access device.
Further, specific as shown in figure 8, rotating counterclockwise due to handle 3, makes third pivoting point 34 also can be counterclockwise
Rotation drives supporting rod 10 to move, since the placement of steering wheel 76 of electric traction head 7 is in the trailing wheel 82 on the ground
It in same level and will not move up and down, then the horizontal plane where the universal wheel 81 of Rear frame 8 can be higher than the steering wheel
76 and 82 place horizontal plane of trailing wheel.In this way, the universal wheel 81 of Electric disability vehicle will not hinder to drive a vehicle.
When needing using common hand wheelchair, the button 32 of lower handle 3 is pressed, and the handle 3 is square clockwise along figure
To rotation, drive block 4 resets under the action of reduction torsion spring 41 at this time, and round pin resets under the action of spring 91.Thus
Casing 83 and the connecting rod 14 can be pulled away from, such Rear frame 8 is detached with electric traction head 7, as the general of Rear frame 8
Leading to hand wheelchair can be used by common hand wheelchair.
In addition to the Electric disability vehicle in above-described embodiment, in other embodiments, the stepping quick access device can also connect
The Rear frame for connecing ordinary bicycle forms ordinary bicycle, or can also connect the Rear frame of common electric vehicle, to become
Common electric motor car with two wheels etc., if Rear frame include the casing 83 that can be connect with stepping quick access device can be with step of the invention
The product or structure to form needs are coupled into quick access device.The present invention still there are many embodiment, it is all using equivalents or
Equivalent transformation and all technical solutions formed, are within the scope of the present invention.
