A lifting mechanism includes a lifting member, a first magnetic member, a rotating arm, a second magnetic member and a resilient member. The lifting member is pivoted to a first casing. The first magnetic member is fixed on the lifting member. The rotating arm is pivoted to a second casing. The second magnetic member is fixed on the rotating arm for attracting the first magnetic member as being rotated with the rotating arm to where the second magnetic member is aligned with the first magnetic member, so as to retract the lifting member inside the first casing. The resilient member resiliently abuts against the second casing and the lifting member for pushing the lifting member as being rotated with the rotating arm to where the second magnetic member is not aligned with the first magnetic member, so as to expand the lifting member out of the first casing. |
