Use said structure, be possible to prevent the people being sitting on chair injured, safety；Elastic component can ensure that ratchet upwardly ratchet simultaneously, makes ratchet operate.
As preferably, described pawl point and breach clamping.
Using the fixing of said structure, beneficially pawl point and breach, both are synchronized with the movement, and beneficially limiting gear group rotates down.
As preferably, the cross section of described pawl point is triangle, and its two hypotenuses are respectively provided on the both sides inwall of breach, and the hypotenuse in chair foot direction of rotation outwardly is more than and away from the hypotenuse in chair foot direction of rotation outwardly.
Use said structure, the hypotenuse of the pawl point in the gear train direction of rotation upward more than and the hypotenuse of pawl point in gear train direction of rotation down, beneficially gear train rotates upward.
As preferably, being provided with girth member between described adjacent chair foot, described girth member includes hollow fixing bar and the adjusting rod being set in fixing bar.
Use said structure, be conducive to reinforcing chair, and girth member is adjustable, it is adaptable to the situation of differing heights.
As preferably, in described fixing bar, it is provided with slide rail, and described adjusting rod is provided with pulley.
Use said structure, reduce fixing frictional force between bar and adjusting rod.
As preferably, described fixing bar is provided with fixing hole, and described adjusting rod is provided with the adjustment hole coordinated with fixing hole；Pass through screw bolt passes fixing hole, adjustment hole between described fixing bar and adjusting rod and fix.
Using said structure, bolt is fixed, sound construction, safety.
By using technique scheme, have the advantages that simple in construction, height adjustable, fixation.
