In some embodiments, when the pressing module is mounted on the mounting opening of the panel from the outside of the panel of the terminal device, the locking portion 304 is buckled on the outside of the panel 50. With the blocking action of the snap portion 304, it is possible to prevent the entire pressing module from being squeezed into the interior of the terminal device. Optionally, the buckle portion 304 and the outer surface of the panel 50 may be adhesively fixed by a viscous medium. The viscous medium can be, for example, glue. The viscous medium bonds the buckle portion 304 to the terminal device to prevent the entire pressing module from falling off.
