In the embodiment shown, the heat sink assembly and the fan assembly are detachably connected by magnetic attraction. For example, a plurality of first magnetic members 114 are disposed on the front side of the first front housing 64, a plurality of second magnetic members 116 are disposed on the rear side of the second rear housing 90, and the first magnetic members 114 and the second magnetic members 116 are corresponding in position and are magnetically attracted to each other. The first magnetic member 114 and the second magnetic member 116 may be magnets having different magnetism, or one of the first magnetic member 114 and the second magnetic member 116 may be a magnet, and the other may be a metal having magnetism.

In the illustrated embodiment, the first jaw 14a and the second jaw 16a are made of a metal material, the first front shell 64 fixedly connected to the first jaw 14a and the movable element 110 fixedly connected to the second jaw 16a are made of a plastic material, and the hardness of the first jaw 14a and the second jaw 16a is greater than that of the first front shell 64 and the movable element 110, so as to enhance the structural strength of the first clamping member 14 and the second clamping member 16, and to enable the mobile phone to be clamped more stably. The inner sides of the first clamping piece 14 and the second clamping piece 16 can be respectively provided with soft rubber pads, so that damage to the mobile phone when the mobile phone is clamped is avoided, meanwhile, a buffering effect can be achieved, and clamping stability is improved.

The concepts described herein may be embodied in other forms without departing from the spirit or characteristics thereof. The particular embodiments disclosed should be considered illustrative rather than limiting.
