[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Example 1, as Figures 1-3 As shown, a portable 3D digital design projector, by loosening the first fastening bolt 5, which no longer abuts against the second support column 4 on the outside of the first storage box 6, pulls the first fastening bolt 5, causing the second support column 4, support plate 2, and first support column 3 to slide within the first groove in the first storage box 6. When storing, pulling the first fastening bolt 5 causes the second support column 4, support plate 2, and projector body 1 to retract into the first storage box 6, where the projector body 1 is stored. When the projector body 1 is in motion, pulling the first fastening bolt 5 drives the second support column 4 and the support plate 2, causing the projector body 1 to extend out from the through hole in the first storage box 6. Alternatively, pulling the first fastening bolt 5 can drive the second support column 4 and the support plate 2 to move the projector body 1 up and down in the second slide groove, adjusting the projection angle at one end of the projector body 1. After adjustment, tighten the first fastening bolt 5 to fix the position of the second support column 4 and the support plate 2 on the first storage box 6, thereby completing the adjustment of the projection tilt angle of the projector body 1.
[0022] Example 2, as Figure 2 and Figure 4 As shown, a portable 3D digital design projector is provided. When the projector body 1 is stored in the first storage box 6, the projector body 1 is located inside the first storage box 6. One side of the first storage box 6 is rotatably connected to the second storage box 10 via the connecting block 11, and the second storage box 10 rests against the first storage box 6. Then, the handle strap 7 is placed on the top side of the second storage box 10. Next, the second fastening bolt 9 passes through the fixing strap 8 installed on the handle strap 7 and is threaded onto the top of the second storage box 10. At this time, the second fastening bolt 9 fixes the fixing strap 8 on the second storage box 10. Thus, the fixing strap 8 and the handle strap 7 are used to fix the first storage box 6 and the second storage box 10 that are currently abutting each other. At this time, the second storage box 10 contains the first extension rod 13 and the second extension rod 14. Thus, after combining the first storage box 6 and the second storage box 10, the projector body 1, the first extension rod 13 and the second extension rod 14 are stored and carried together.
[0023] It should be noted that this utility model is a portable 3D digital design projector. In use, the first storage box 6 and the second storage box 10 are used to store the projector body 1, the first extension rod 13, and the second extension rod 14, respectively. Then, the first storage box 6 and the second storage box 10 are connected to form a whole by the handle strap 7, the fixing strap 8, and the second fastening bolt 9. By pulling the handle strap 7, the fixing strap 8 drives the second fastening bolt 9, which in turn drives the second storage box 10 and the first storage box 6. This makes it convenient to carry the projector body 1, the first extension rod 13, and the second extension rod 14 as a whole. The overall storage of the device is more standardized, and the loose parts are less likely to be lost.
[0024] When the second storage box 10 needs to be opened, loosen the second fastening bolt 9. After the second fastening bolt 9 is released from the fixing band 8, tighten it back onto the second storage box 10 to prevent loss. The second storage box 10 rotates and folds onto the bottom of the first storage box 6 via the connecting block 11. The second storage box 10 supports the bottom of the first storage box 6. Then, pull the rubber pad 15 to drive the second extension rod 14. Screw the threaded end of the second extension rod 14 into the threaded end of the first extension rod 13. Then pull the second extension rod 14 to drive the first extension rod 13. 3. Extend from the second storage box 10, screw the threaded end of the first extension rod 13 into the threaded part of the second storage box 10, so that the first extension rod 13, together with the second extension rod 14 and the rubber pad 15, serves as an extension support for the second storage box 10. The second storage box 10, the first extension rod 13, the second extension rod 14 and the rubber pad 15 also serve as a height-increasing support for the bottom of the first storage box 6. The first storage box 6 drives the support plate 2 to raise the projector body 1, so that the projection height is higher, thus achieving the purpose of assisting in raising the projection height of the projector body 1.
