[0006] Preferably, the protective cover assembly includes an external protective cover, the external protective cover is connected to the upper end of the main rod, a sliding seat is slidably connected to the outer wall of the main rod, four notches are formed in the circumference of the edge of the sliding seat, a rotating shaft is connected to each notch, a support rod is rotatably connected to each rotating shaft, and four hinge seats are equidistantly connected to the inner wall circumference of the external protective cover, and the upper end of each support rod is movably connected to a corresponding hinge seat.

[0007] Preferably, a ring-shaped gasket is connected to the edge of the external protective cover.

[0008] Preferably, the gasket is made of rubber.

[0009] Preferably, the external protective cover is composed of several fan blades overlapping each other and can be contracted.

[0010] The beneficial effects of the present utility model are as follows: for the plugging device for the reserved hole of the house, when in use, slide the sliding seat downward to make the protective cover contract into a rod shape, then pass through the reserved hole from the indoor to the outdoor, pull the main rod from the indoor, the support rod will support the external protective cover against the hole opening and press it against the hole opening in the reverse direction. After passing the internal hole plugging plate through the main rod from the indoor, fasten it with a nut to make the internal hole plugging plate fit tightly with the inner wall; it can tightly plug the reserved hole in the outer wall, avoid rainwater leakage and prevent mosquitoes from entering, and is simple and convenient to use.
