Abstract

A terminal device with a folding screen includes a coupling device with a middle frame fixing member, a first transmission assembly, a second transmission assembly and a third transmission assembly. A first transmission assembly is rotatable relative to the middle frame fixing member during rotation of the middle frame fixing member. The second transmission assembly has a first end hinged to the first transmission assembly and a second end slidably coupled to the first transmission assembly, and the second transmission assembly converts a rotation action of the first transmission assembly into a moving action along a second direction. A 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.
