So set up, can block the table through the design of draw-in groove and latch, make it directly pull out from accomodating the groove.

The utility model discloses further set up to: the bottom of the movable plate is provided with an inserting block, a Z-shaped structure is formed between the inserting block and the movable plate, and the backrest is provided with an inserting groove matched with the inserting block.

So set up, realize the relative activity between fly leaf and the back, and need not the very thick of setting up the back.

The utility model discloses further set up to: the backrest is connected with the movable plate through a bolt, a threaded hole matched with the bolt is formed in the backrest, an insertion hole is formed in the insertion block, and the bolt penetrates into the insertion hole after passing through the threaded hole.

So set up, make the fly leaf can only be in bolt axial activity, for can not deviate from in the back.

The utility model discloses further set up to: the elastic force application part is a compression spring which is sleeved on the bolt.

To sum up, the utility model relates to a distance between chair passing through setting up of telescopic link realization table and the people is adjusted, makes the utility model discloses can adjust the table position according to user's demand, improve use comfort and application scope.
