Abstract: A multi-mode includes a chassis, a height adjustor and an angle adjustor. The height adjustor includes an external tube pivotally connected to the chassis between a vertical position and a horizontal position and an internal tube telescopically inserted in the external tube so that the height adjustor is made with an adjustable effective length. The angle adjustor includes a platform, two lateral plates, an axle and a pin. The lateral plates extend parallel to each other and from the platform. Each of the lateral plates includes a plurality of apertures. The axle is used to pivotally connect the lateral plates to the internal tube, which is located between the lateral plates. The pin is operable to insert in the internal tube via a selected one of the apertures to keep the platform in a selected one of several angles relative to the internal tube.
