The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

Referring to Figures 1-2, a display stand that facilitates the display of project cost budget results includes a base 1, and two brackets 2 are symmetrically arranged on the upper side wall of the base 1, and a whiteboard 6 is fixedly connected to the inner side walls of the two brackets 2 together. The outer wall of one bracket 2 is provided with a storage basket 5 for placing whiteboard pens and whiteboard erasers. The upper side walls of the two brackets 2 are connected with an extension frame 4, and the upper side wall of the bracket 2 is provided with a groove. The lower side is inserted in the groove, the outer wall of the bracket 2 is provided with a threaded port that communicates with the interior of the groove, the threaded port is screwed with a fastening bolt 3, and the extension frame 4 is provided with a plurality of through ports with the same size as the threaded port. , move the extension frame 4 up and down in the groove of the bracket 2 to a suitable height, align the threaded opening on the bracket 2 with one of the through openings on the extension frame 4, and then rotate the fastening bolt 3 to the threaded opening and the through opening The height adjustment and fixed support of the extension frame 4 are realized.

The inner side walls of the two extension frames 4 are fixedly connected with a bearing 8, and a same rotating rod 9 is inserted between the two bearings 8. The rotating rod 9 is fixedly connected with a curtain 10, and the lower end of the curtain 10 is fixedly connected with a sleeve. 11. The sleeve 11 can increase the falling weight of the curtain 10 and has the effect of flattening and not warping the curtain 10. One end of the rotating rod 9 penetrates the bearing 8 and the extension frame 4 and is fixedly connected with a rotating handle 19, which is driven by the rotating handle 19. The rotating rod 9 rotates in the bearing 8 to rewind or unfold the curtain 10. The lower side wall of the sleeve 11 is symmetrically provided with an elastic rope 12 located on the upper side of the base 1, and the end of the elastic rope 12 away from the sleeve 11 is fixedly connected with a circular ring. 13. Double-sided hooks 14 are symmetrically arranged on the front side wall of the base 1, and the two double-sided hooks 14 are respectively arranged symmetrically with the elastic rope 12. After unfolding the curtain 10, pull the ring 13 and set it on the double-sided hooks 14. The fixed curtain 10 does not move vertically downward, the end of the extension frame 4 away from the bracket 2 is provided with a slot, a baffle 18 is inserted in the slot, and the outer wall of the extension frame 4 is threadedly connected with a threaded rod whose end is located in the slot. 16.
