The invention discloses a variable-operating-area lifting platform which comprises a plurality of flat plates arranged in the vertical direction, wherein a height adjusting component is mounted between any two adjacent flat plates, and comprises a driving component and at least two parallelly-arranged connecting rods; both ends of each connecting rod are rotationally connected with the surfaces of the two adjacent flat plates correspondingly; one of the connecting rods is driven by the driving component to rotate; the corresponding connecting rods are driven by the driving component of each height adjusting component to rise, so that the distance between the adjacent flat plates is increased and the flat plates are in a rising state; and the corresponding connecting rods are driven by the driving components of the multiple uppermost height adjusting components to topple, so that the flat plates are stacked in a staggered manner. According to the variable-operating-area lifting platform, the multiple flat plates are arranged in the height direction in a staggered manner; the multiple uppermost flat plates move laterally, are lowered in height, and are stacked together; the uppermost operating area is convenient to expand; and furthermore, the variable-operating-area lifting platform can serve as a cargo storage rack, thereby reducing the stacking area of stacked cargos.

The invention provides a virtual cursor-based touch screen terminal operation method, a terminal and a medium. The method comprises the following steps of: receiving a finger pressing operation inputin an operation area by a user, so as to generate a virtual cursor; receiving a first finger movement operation input in the operation area by the user, and controlling the virtual cursor to move according to a preset first movement proportion; receiving a click operation input in the operation area by the user, controlling an object at a position where the virtual cursor is located to execute theclick operation, and storing the position of the virtual cursor in the click operation. According to the method, the user finger can directly move in the operation area, so that the virtual cursor can move in a touch screen of the whole mobile terminal; and the operation area is relatively small, so that the user can slide and click in the small-area operation area via a single hand, sliding andclick in the touch screen of the whole mobile terminal are realized, and then the defect that large-screen mobile phones cannot be operated by a single hand in the prior art is solved.
