[0029] A retractable drawing display rack for land planning includes a mounting tray 1, a first mounting base 2, and a second mounting base 3. First connecting blocks 4 are fixed to both sides of the first mounting base 2, and first mounting rods 5 are movably connected to the first connecting blocks 4. Second connecting blocks 6 are fixed to both sides of the second mounting base 3, and second mounting rods 7 are movably connected to the second connecting blocks 6. The first mounting base 2 is fixed to the mounting tray 1, and a connecting rod 8 is fixed to the top of the first mounting base 2. The second mounting base 3 is rotatably and non-sliply fitted over the connecting rods 8. When the first mounting rods 5 and 7 are rotated horizontally to a horizontal position, they are in an unfolded state for hanging and displaying drawings. When the first mounting rods 5 and 7 are rotated vertically to a vertical position, they are in a folded storage state. A first elastic cord 9 connects the two first mounting rods 5. The first mounting base 2 and the first connecting blocks 4 have openings for the first elastic cord. The first through hole 10 through which the second mounting rod 7 passes is provided. The first mounting rod 7 is provided with a first insert 11 on each of the two first mounting rods 5. The first connecting block 4 is provided with a first slot 12 and a second slot 13 that cooperate with the first insert 11. When the first mounting rod 5 is in a horizontal state, the first insert 11 cooperates with the first slot 12. When the second mounting rod 7 is in a vertical state, the first insert 11 cooperates with the second slot 13. A second elastic rope 14 is connected between the two second mounting rods 7. The second mounting base 3 and the second connecting block 6 are provided with a second through hole 15 for the second elastic rope 14 to pass through. The second mounting rod 7 is provided with a second insert 16 on each of the two second mounting rods 7. The second connecting block 6 is provided with a third slot 17 and a fourth slot 18 that cooperate with the second insert 16. When the second mounting rod 7 is in a horizontal state, the second insert 16 cooperates with the third slot 17. When the second mounting rod 7 is in a vertical state, the second insert 16 cooperates with the fourth slot 18.
[0030] In practical applications, both the first mounting rod 5 and the second mounting rod 7 are in a horizontally extended state. At this time, the first insert 11 on the first mounting rod 5 is inserted into the first slot 12, and the second insert 16 on the second mounting rod 7 is inserted into the third slot 17. The drawings are displayed on the first mounting rod 5 and the second mounting rod 7. When it is necessary to store the display rack, first remove the drawings, rotate the second mounting base 3 by 90 degrees, pull the first mounting rod 5 outward, and move the first insert 11 out of the first slot 12. The first elastic rope 9 is in a stretched state. Insert the first insert 11 on the first mounting rod 5 into the second slot 13, so that the first mounting rod 5 is in a vertical state. In the same way, move the other first mounting rod 5 and the two second mounting rods 7 to a vertical state. At this time, the storage is completed. In order to improve stability, straps or cable ties can be tied around the entire first mounting rod 5 and the second mounting rod 7.
