During original state, angle modulation slides fortune block 461 and the right-most position transported in groove 46 is slided positioned at first, now, slides angle modulation
The bilateral tapered right side of the wheel 436 cone flank of tooth between the guid arm 462 of two groups of 461 front end of fortune block engages connection with the first tapered wheel 431,
Then the now bilateral tapered left side of the wheel 436 cone flank of tooth, passes through the 3rd power set 434 at utmost away from the second tapered wheel 432
Drive clamping shaft 435 to circle round, drive bilateral tapered wheel 436 to circle round by clamping shaft 435, the bilateral tapered drive first of wheel 436 is tapered
Rotation cylinder 441 on 431 and first tapered wheel 431 of wheel, and then drive spiral shell type line rotation cylinder 442 to circle round by rotation cylinder 441, by spiral shell type line
Rotation cylinder 442 drives interior spiral shell type lock sleeve 413 to circle round, and interior spiral shell type lock sleeve 413 is driven composite pad 414 and the left surface of locking plate 42
Abut against as shown in figure 4, now, composite pad 414 encounters the trigger 421 of the left surface of locking plate 42, believes trigger 421
Number and control the 3rd power set 434 to stop convolution, simultaneously because composite pad 414 offsets with the left surface of locking plate 42, now for
Locking state.
When needing pedal angle modulation, drive the first spiral shell type bar 32 to circle round by the first power set 33 first, make first
Spiral shell type bar 32 drives first to slide the right-most position that fortune block 34 is moved in the second cunning fortune groove 31, and then is slided by first and transport the band of block 34
Dynamic second trestle 5 is moved to the right-most position of the top surface of pedal base 3, then by the clamping slot 61 and first in the left end of pedal 6
The 511 fully mated connection of clamping block on the right side of convolution fastener 51 of the right-hand member of trestle 4, meanwhile, make the convolution of the left end of the second trestle 5
The clamping block 511 in the left side of fastener 51 is in relative position with the clamping slot 61 in the right-hand member of pedal 6, then passes through the first power
Device 33 drives the first spiral shell type bar 32 reversely to circle round, and makes the first spiral shell type bar 32 drive first to slide fortune block 34 and first and slides fortune block 34
Second trestle 5 at top is slided along second transports the left direction of groove 31 cunning fortune, until the left side of convolution fastener 51 of the left end of the second trestle 5
The fully-inserted right-hand member of pedal 6 of clamping block 511 in clamping slot 61 in, now control the first power set 33 stop convolution,
Then drive clamping shaft 435 reversely to circle round by the 3rd power set 434, drive bilateral tapered wheel 436 reverse by clamping shaft 435
Convolution, and then the first tapered wheel 431 reversely convolution is driven by bilateral tapered wheel 436, rotation cylinder 441 is driven by the first tapered wheel 431
And the spiral shell type line rotation cylinder 442 of the rotation right side end pin of cylinder 441 reversely circles round, and then interior spiral shell type is driven to lock by spiral shell type line rotation cylinder 442
Set 413 moves along the left direction of locking device 411, meanwhile, gradually left direction moves guiding block 415 along guide channel 412, this
When, interior spiral shell type lock sleeve 413 is gradually distance from the left surface of locking plate 42, until interior spiral shell type lock sleeve 413 is moved to locking device
Left-most position in 411, now, the 3rd power set 434 of control stop convolution, then pass through the band of the second power set 464
Dynamic angle modulation spiral shell type bar 463 circles round, and drives angle modulation to slide fortune block 461 by angle modulation spiral shell type bar 463 and is gradually moved into the first cunning fortune groove 46
Left-most position when, now, bilateral tapered wheel 436 432 engages connection with the second tapered take turns, and then passes through the 3rd power set
434 drive clamping shafts 435 circle round, and drive the bilateral tapered convolution of wheel 436 by clamping shaft 435, bilateral tapered wheel 436 drives the second cone
Type wheel 432 is circled round, and then is circled round by the second first swing arm 433 of the tapered drive of wheel 432, and locking plate 42 is driven by the first swing arm 433
And the second swing arm 45 of the right flank of locking plate 42 circles round, and then driven by the convolution fastener 51 of the right side end pin of the second swing arm 45
Pedal 6 between the convolution fastener 51 in the left side of 51 and second trestle of convolution fastener 5 of the right side end pin of the second swing arm 45 returns
