Claim 19:
20. Terminal equipment, comprising:
a screen; and
a coupling device coupled to the screen,
wherein the coupling device comprises:
a middle frame fixing member;
a first transmission assembly rotatable relative to the middle frame fixing member during rotation of the middle frame fixing member;
a second transmission assembly having a first end hinged to the first transmission assembly at a first hinge center and having a second end slidably coupled to the first transmission assembly, wherein a rotation center of the first transmission assembly does not coincide with the first hinge center, and the second transmission assembly and the first transmission assembly form a crank connecting rod mechanism, and the second transmission assembly converts a rotation action of the first transmission assembly into a moving action of the second transmission assembly along a second direction; and
a third transmission assembly having a first end hinged to the second transmission assembly and having a second end and a third end both slidably coupled to the middle frame fixing member, wherein the second end and the third end of the third transmission assembly are on two sides of the first end of the third transmission assembly, and the third end of the third transmission assembly pushes the middle frame fixing member to move towards a first side facing away from the first transmission assembly or a second side towards the first transmission assembly during the rotation of the middle frame fixing member.
