[0014] The technical solutions in the embodiments of the utility model are described clearly and completely below. The embodiments of the utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1-2 As shown, the portable aluminum alloy template rear opening plugging device of the preferred embodiment of the utility model comprises: a rotating knob 1, a threaded rod 2, an annular rubber ring 3, a connecting baffle 4, a circular rubber block 5 and a pad 6. The rotating knob 1 is a cylindrical structure, and one end of the threaded rod 2 is threadedly connected to the inner wall of the rotating knob 1 for fastening the plugging device. An annular rubber ring 3 is arranged around the threaded rod 2 to protect the threaded rod. The connecting baffle 4 is a circular plate-like structure, which is fixedly connected to the other end of the threaded rod 2. A circular rubber block 5 is arranged below the connecting baffle 4 to seal the hole and prevent the concrete cement slurry from being exposed. The pad 6 is a circular plate-like structure, which is arranged below the circular rubber block 5 and connected to the connecting baffle 4 through a connecting rod 7. The diameters of the pad 6 and the circular rubber block 5 are equal, both equal to the diameter of the hole of the aluminum alloy template, and the diameter of the connecting baffle 4 is greater than the diameter of the hole of the aluminum alloy template.
