The operation principle and workflow of the present invention：The adjustable pulling wire handle with self-return function that the present invention is provided
Mechanism, with solve it is existing in the case of, air spring seat has height adjusting function, by arranging different gears, rotates handss
Handle, is adjusted by gear, bracing wire 30 is adjusted, it is possible to achieve any regulation to height of seat, often rotates a handle,
The corresponding generation of height of seat once changes, multiple rotary handle, and the position of handle is different, brings not to the personnel for using
Just problem.When adjusting height of seat, knob 15 is rotated clockwise, drive the ratchet 122 of rotating disk 12 and first and the second ratchet
123 common rotations, in the presence of the first limited block 13, the bottom of the first ratchet 122 to the position near the center of circle of rotating disk 12 is moved
Depart from the dentalation on ratchet 21, the second ratchet 123 drives ratchet 21 and housing 10 to rotate, and housing 10 is rotated clockwise,
Bracing wire 30 is lowered to drive gear change, height of seat to change, and when knob 15 rotates, drives winding torsion bullet thereon
Spring twists, due to having put aside elastic potential energy in torque spring, when acting on without external force on knob 15, torque spring due to
Recover elastic deformation, turn round knob 15, the revolution of knob 15 drives the ratchet 122 of rotating disk 12 and first and the second ratchet 123
Rotate counterclockwise, now, the first ratchet 122 is engaged with the dentalation on ratchet 21, however, because the first spring tooth bar 51 is
It is fixedly installed, second spring tooth bar 52 engages setting with the first spring tooth bar 51 and the outer surface of cap 20, and cap 20 is in the first bullet
Under the property overall function of part 50, remain stationary as, the first ratchet 122 is engaged respectively with the second ratchet 123 with ratchet 21, the length of bracing wire 30
It is motionless.It follows that the adjustable pulling wire handle mechanism with self-return function that the present invention is provided can be in the length of bracing wire 30 not
In the case of change, handle is set to realize self-return.
Finally it should be noted that：Various embodiments above only to illustrate technical scheme, rather than a limitation；To the greatest extent
Pipe has been described in detail with reference to foregoing embodiments to the present invention, it will be understood by those within the art that：Its according to
So the technical scheme described in foregoing embodiments can be modified, either which part or all technical characteristic are entered
Row equivalent；And these modifications or replacement, do not make the essence disengaging various embodiments of the present invention technology of appropriate technical solution
The scope of scheme.
