[0025] The shape of the slider 6 is set in an I-shape, and the bottom end of the groove of the protective shell 2 is fixedly connected to the limit block 8. Through the setting of the slider 6, when the slider 6 slides in the inner cavity of the groove of the protective shell 2, it avoids the inner cavity of the groove of the threaded protective shell 2, thereby improving the stability of the slider 6 when sliding. Through the setting of the limit block 8, the slider 6 is prevented from sliding out from the other end of the groove of the protective shell 2.

[0026] The inner cavity of the protective shell 2 is provided with a limit plate 9, and the limit plate 9 is located between the touch screen body 1 and the heat dissipation component 4. The surface of the limit plate 9 is hollowed out.
