When the opening and closing force of the flip cover 20 is too large, that is, a large force is required to open the flip cover 20, which is quite strenuous and the flip cover 20 does not feel good. When the opening and closing force of the flip cover 20 is too small, that is, a very small force is required to open the flip cover 20, the flip cover 20 is easy to open accidentally and affect normal use.
