As optimization, described fixing pin is positioned at the lower carriage outside one end and is provided with circular retaining head, and open slot is a square groove, and a retaining diameter is wide greater than open slot.During use, the retaining head is stuck in the outside of open slot, helps resetting of fixing pin.
As optimization, described slide block pad is elongated, and the width of slide block pad is slightly less than the opening of guide rail, and this structure makes the relative motion of slide block and guide rail level and smooth more, easy.
As optimization, upper bracket top is provided with desktop or seat and is fixedly coupled part, and connector is provided with the hole, and the hole makes things convenient for the screw or the bolting of connector and desktop or seat.
As optimization, the bottom of slide block is a wedge shape, and the lower carriage bottom is provided with base, and base is used to support entire table or chair, helps integrally-built stability.The bottom enters guide rail for the slide block of wedge is beneficial to.
Liftable study table of the present utility model, its tables and chairs panel can adopt one-time formed mould plate, or adopts multi-plywood also can adopt all kinds of sheet materials such as core-board, specifically can according to circumstances select.
That liftable of the present utility model study table has is simple in structure, good stability, environmental protection, advantage such as practical, can regulate the height of tables and chairs by lowering or hoisting gear, can effectively prevent child because myopia and spinal curvature or the hunchback that abnormal sitting posture really causes.
