The display stand has a fixed size and occupies a large storage space, which is inconvenient to carry. In addition, the display structure of the display stand may collide with foreign objects during movement and thus be damaged. Therefore, a display stand for displaying the results of engineering cost budget is needed to solve the above problems. Utility Model Content

[0014] The utility model is provided with an operating block, a coil spring, a threaded rod, a folding frame, a top plate, a ratchet, a pawl and a sealing pad. The operating block is rotated forward, and the unfolded folding frame drives the top plate to move upward through the guide block and the guide rod. The top plate moving upward moves the display cloth out of the winding roller, and the winding roller drives the rotating rod to rotate, and the coil spring is twisted. In this process, the top plate moving upward can drive the display cloth to move to different heights, and then the user can record the budget result of the project cost on the front side of the display cloth. When the device is used, the pressing rod is pushed downward, and the rotating pressing rod drives the pawl to disengage from the ratchet, and the operating block is reversed at the same time. The top plate moves downward, and the winding roller rewinds the display cloth under the action of the coil spring until the top plate contacts the sealing pad. At this time, the size of the device is reduced, so that the device can be conveniently carried, and because the display cloth is stored between the top plate, the base and the sealing pad, when the device moves, the display structure of the device is not easy to collide with foreign objects and thus be damaged.

[0015] The utility model provides a limiting groove and a threaded block. Since the threaded block is slidably connected in the limiting groove, the limiting groove can limit the threaded block, so that the threaded block can move smoothly along its axial direction under the action of rotating the threaded rod.
