1. A hinge connectable between a first device part and a second device part to permit the second device part to rotate relative to the first device part, comprising:
a base seat unit including a first base seat for connecting with the first device part, and a second base seat for connecting with the second device part, said first base seat having a base plate, said base plate having a first side, a second side opposite to said first side, an upper side and a lower side opposite to said upper side, said base plate being formed with a moving slot, said moving slot having a first slot portion which extends from said first side toward said second side, and a second slot portion which is in communication with said first slot portion and which extends from said first slot portion toward said upper side; and
a rotating unit including a rotating axle which movably extends through said moving slot and which is securely connected with said second base seat so as to be rotated with said second base seat, a linkage which is pivotally connected between said base plate and said rotating axle, and a cam piece which is securely mounted on said rotating axle, said cam piece having a cam surrounding portion which is securely sleeved on said rotating axle, and a first protrusion which projects radially from said cam surrounding portion and which is movably disposed in said first slot portion,
wherein said second base seat is driven to rotate said rotating unit between an initial position, where said rotating axle is located in said first slot portion and said first protrusion of said cam piece is located in said first slot portion adjacent to said first side, and a first rotating position, and
wherein, during rotation of said rotating axle and said cam piece, said first protrusion of said cam piece abuts against and is moved along a lower edge of said first slot portion to bring said rotating axle into an upward movement into said second slot portion and bring said linkage into an upward pivoting action so as to move said rotating unit to the first rotating position.
