The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1～Fig. 5, the utility model comprises Compress Spring 1, limit shaft 2, spring locating shaft 3, backrest 4, handrail 5 etc.Compress Spring 1 is arranged between backrest 4 and handrail 5 by spring locating shaft 3.Be provided with two limit shafts 2 on backrest 4; Be provided with two bar-shaped trough 5-1 on handrail 5; Article two, limit shaft 2 lays respectively in two bar-shaped trough 5-1, and can move back and forth within it, thereby plays position-limiting action.
During real work, after backrest 4 was subject to extraneous pressure, corresponding distortion can occur in Compress Spring 1, makes circular motion with spring locating shaft 3 as axis of rotation.Meanwhile, limit shaft 2 also can produce displacement in bar-shaped trough 5-1, and reaches position-limiting action by it.After external force disappeared, under the elastic force effect of Compress Spring 1, initial position was got back to by whole mechanism.
