It is preferred that, restriction plate 52 opens up the second axis hole 521, and the driven spindle 43 that the second axis hole 521 Gong passes is passed through, restriction plate 52 by
First axis hole 511 and the second axis hole 521 communicate realization and concede the first axis hole 511, and restriction plate 52 is by the first axis hole 511 and second
The dislocation realization of axis hole 521 shelters from the first axis hole 511.
During dislocation, driven spindle 43 is stopped by restriction plate 52 and can not pass the first axis hole 511, that is to say, that clutch plate
42 will be with the power connector of driving disc spacing pressing 41.When communicating, then allow driven spindle 43 to pass the first axis hole 511 and enter the second axis hole
521, that is to say, that clutch plate 42 can be free to move axially, then once driving disc spacing pressing 41 is rotated, then clutch plate 42 can skid de-
From driving disc spacing pressing 41, power connector is disconnected.
Therefore key is how automatically moving for restriction plate 52 is realized in particular moment, thus realize above-mentioned dislocation or
Communicate, described in the following structure of implementation process.
Drive rod 53 is articulated in inside casing 1 in the way of it can horizontally rotate, and drive rod 53 is fixed to drive with restriction plate 52

Move the position communicated to the first axis hole 511 and the second axis hole 521, that is to say, that after pedal 10 is overturn in place, the He of the first axis hole 511
Second axis hole 521 is communicated immediately, and plate clutch 4, which skids, disconnects power connector, without worrying that driving gear 13 rotates excessive, carries
The high accuracy of turn-over.And driving gear 13 then can increase the rotation of driving gear 13 the problem of rotate inadequate in design
Surplus can be solved.
Pushing block 55 is installed on the bottom of housing 2, and the top of pushing block 55 has an inclined-plane, when drive rod 53 is displaced downwardly to bottom,
Pushing block 55 is used to promote the rotation of drive rod 53 to make alignment pin 531 leave positioning hole 111, when alignment pin 531 leaves positioning hole 111,
Drive rod 53 drives the movement of restriction plate 52 the first axis hole 511 and the second axis hole 521 is misplaced.That is, being moved in inside casing 1
Before bottom, the first axis hole 511 and the second axis hole 521 are also in communicating state, and plate clutch 4 disconnects power connector, i.e., interior
In the folding process of frame 1 pedal gear 11 will not be caused to rotate and turn-over；And when inside casing 1 is moved to bottom, alignment pin 531 leaves
Positioning hole 111, drive rod 53 drives restriction plate 52 the first axis hole 511 and the second axis hole 521 is misplaced, the power of plate clutch 4

Under 54 effects, alignment pin 531 is pressed on pedal gear 11 and waits positioning hole 111 to arrive sideways, and inside casing 1 continues to rise, pedal 10
Continue turn-over, when turn-over in place when, positioning hole 111 is gone at alignment pin 531, push the spring 54 effect under the quilt of alignment pin 531
Positioning hole 111 is pushed into, drive rod 53 then drives the movement of restriction plate 52 to communicate the first axis hole 511 and the second axis hole 521, now disk
Formula clutch 4 backs off power connector, completes whole turn-over process.
Alignment pin 531 is set to leave the needs one of the positioning hole 111 of short duration time because pushing block 55 promotes drive rod 53 to rotate, because
This is not when inside casing drops to bottom completely, and drive rod 53 can drive restriction plate 52 to move and make the first axis hole 511 and the
The sequence of two axis hole 521, the power of plate clutch 4 combine, and now inside casing 1 can also decline it is a bit of, this it is a bit of will band
