A support base plate 3 is installed at the bottom of the support rod 1, and a connecting ear is installed on the support base plate 3. One end of the placement rod 5 is hinged on the connecting ear of the support base plate 3. According to the needs of the construction project, a plurality of placement rods 5 are configured to increase the contact area between the support device of the present invention and the ground 15 to prevent the support rod 1 from being deflected.
