Stand for a handheld device, means thereof, and a protective case having same

A stand for a handheld device, comprising:

• a first plate having a first area and a second area opposite to the first area thereof;
• a second plate having a first area and a second area opposite to the first area thereof;
• wherein the first area of the first plate is pivotally connected to the first area of the second plate, to form a pivot portion;
• a lifting device arranged between the first plate and the second plate;
• the lifting device including:
• an elastic sheet having a first end portion and a second end portion, the first end portion disposed on the second area of the first plate;
• a limiting device adapted to guide the elastic sheet to move along a length direction of the second plate within a limited range;
• when the second end portion of the elastic sheet and the pivot portion proceed to a first relative displacement, the second area of the first plate and the second area of the second plate is moved to create a second relative displacement, wherein when the first relative displacement becomes smaller, the second relative displacement becomes smaller;
• when the first relative displacement becomes larger, the second relative displacement becomes larger.
