The base has an external insertion recess for a handheld electronic device to insert therein, and being communicable with the receiving space via a through-wall slot. The function module is electrically connectible to an external power supply, and includes a first connector that is extended through the through-wall slot into the insertion recess for electrically connecting to the handheld electronic device, and is smaller than the through-wall slot. The adjusting unit includes a press plate fixedly connected at an end to the function module, at least one elastic element, and at least one pivot bolt extended through the elastic element and the other end of the press plate into a wall of the base, such that the elastic element is movably connected to the press plate.
