The purpose of utility model reaches by the following technical programs: the forward and backward stool leg by a top board and four roof supportings is made, be connected with cross bar between each stool leg, it is characterized in that: be hinged with equidistant upper and lower rocking arm between two preceding stool legs; rocking arm is connected with a S type adjustable shelf, is fixed with upper and lower panel on the adjustable shelf.

Described upper and lower rocking arm two ends are inserted the stage casing that constitutes jointed shaft, each panel and corresponding rocking arm in the hole on the stool leg respectively and are connected to form the overall structure that can rotate around jointed shaft.

Described adjustable shelf top is supported and lower end support landing ground by rocking arm.

Below in conjunction with accompanying drawing and embodiment structure of the present utility model, principle are further described.

Embodiment that below provides and accompanying drawing thereof only are the application's a preferred example; can not limit to the application's protection domain with this; all and the application's claims and the described structure of specification, technical characterictic is identical or its equivalent transformation design, all belongs to the application's protection domain.

The retractable instrument stool user mode schematic diagram of ascending a height that Fig. 1 the utility model provides.
