Abstract

The invention relates to a chair, in particular to a desk chair with a position memory function. The invention provides a desk chair with a position memory function, which is simple to operate, convenient to use and capable of saving space. The desk chair with a position memory function comprises a support and a sliding mechanism, wherein the inner side of the upper portion of the support is connected with the sliding mechanism; and a clamping mechanism which is arranged on the sliding mechanism. According to the invention, the ripping bar is matched with the wedge-shaped block, the wedge-shaped block enables the ripping bar to rotate, then the second pull rope is pulled, and the second pull rope moves to enable the connecting block to move leftwards and rotate, so that the backrest plate rotates upwards, manual rotation is replaced, time and labor are saved, the ejector rod is matched with the wedge-shaped block, and the wedge-shaped block enables the ejector rod to move upwards so the sliding rod slides upwards and the armchairs move upwards; when a user sits on the bearing cushion, the user can lean the two hands against the armrests, and therefore convenience is achieved.
