This application has reduced the friction between inside and outside thimble wall through the cooperation of rib and spacing buffering folded plate, and lift operating stability is better, and the noise is few, and can only set up the effect that the elastic component just can realize this application on spacing buffering folded plate is local, need not the large tracts of land and sets up the elastic component. The better prerequisite structure of stability in use is lighter and more handy, simple.
This application realizes through the setting of above-mentioned structure that the chair handrail can both remove and still can rotate about, around. Specifically, when the lateral movement is needed, the fixed plate does not move, and the jacking plate, the bottom connecting plate and the armrest seat move together along the lateral movement track through the operation and control of the lateral movement control component. When the front and back translation is needed, the whole jacking plate and the bottom connecting plate move back and forth together under the control of the front and back translation control part and the back of the translation track and the translation connecting slide block. When the plate needs to rotate, the plate is fixed still, and the rotation and the armrest seat rotate to drive the top holding plate and the bottom connecting plate to rotate. The above structures are closely matched and are skillfully and stably matched, the two structures can be independently operated and can also move together, the operation is convenient, the comfort level is high, particularly, the front and back and side movement pause and pause are less, the sound is light, and all the parts are stably adjusted.
