The controlling assembly has a base body arranged on the main body and a controlling member having a pivot portion and a driving portion, the pivot portion is pivoted to the base body so that the controlling member is swingable between pressurizing and releasing positions, and the pressing assembly has a controlled portion comovable with the driving portion and a pressurizing portion for pressing an object. When the controlling member swings toward the pressurizing position, the driving portion drives the controlled portion to make the pressurizing portion press the object； when the controlling member swings toward the releasing position, the driving portion drives the controlled portion to depressurize the object.
