• a rotating mechanism positioned on an inner side of said element fixing seat and configured in such a manner that, when said element fixing seat is securely mounted on said housing, said rotating mechanism is within the accommodation space, an outer side of said element fixing seat faces outside of said opening, and an output axle of said rotating mechanism is configured to pass through said axle hole and extend outside of said element fixing seat;
• a waterproof washer made of elastic material and having one end embedded into said gap and the other end extending outside of the gap, wherein an outer or inner edge of the other end of said waterproof washer is radially provided with a flange, whereby, when one end of said waterproof washer is completely embedded in said gap, an inner side of said flange can abut against an end edge on one side of said housing or an outer edge of said element fixing seat;
• and
• a packing ring securely mounted onto said housing on a position corresponding to said opening, wherein an inner side of said packing ring abuts against the other end of said waterproof washer and the outer side of said element fixing seat for enabling said waterproof washer to deform under pressure and evenly and watertightly pack within the gap, whereby said element fixing seat and said housing are configured to be watertightly joined into one body, wherein a plurality of through holes are provided on said packing ring, and said packing ring is positioned on the outer side of said element fixing seat by means of a plurality of first screw bolts, and each of said first screw bolts sequentially passes through said through hole and said threaded hole corresponding thereto and is secured inside said housing, so as to simultaneously and securely mount said packing ring and said element fixing seat onto said housing at a position corresponding to said opening.
