In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] As Figures 1 to 4 shown, the software demonstration projection device of this embodiment includes a base 1. Grooves 2 are arranged at both the front and rear ends of the base 1. The grooves 2 are used for placing the connecting rod 4. A placement groove 3 is arranged at the upper end of the base 1 between the two grooves 2. The placement groove 3 is used for placing the projector body 6. The connecting rods 4 are installed inside the grooves 2 through a rotating assembly, and the angle of the connecting rods 4 can be adjusted through the rotating assembly. The projector body 6 is installed between the two connecting rods 4 through a rotating assembly. A projection lens 7 is arranged at the front end of the projector body 6. A push plate 8 is movably installed in the front of the placement groove 3. When the projector body 6 is stored, the push plate 8 can protect the projection lens 7. Four height adjustment components are installed at the lower end of the base 1 in a rectangular array. The height adjustment components are used to adjust the placement height of the base 1.

[0022] Specifically, elastic springs 10 are installed on both sides of the front end of the placement groove 3. The push plates 8 are jointly installed at one end of the two elastic springs 10. A soft pad 11 is installed at one end of the push plate 8 close to the projection lens 7. The elastic springs 10 generate elastic force to push the push plates 8, realizing the contact between the soft pad 11 and the projection lens 7, which plays a protective role for the projection lens 7.

[0023] Furthermore, the rotation assembly includes a rotating shaft 501, a fixing knob 502, and a bearing member 503. Rotating shafts 501 are installed at both ends of the projector body 6 and at one end of the two grooves 2. Bearing members 503 are sleeved on the surfaces of the four rotating shafts 501. The bearing members 503 are installed on the surfaces of the opposite ends of the connecting rod 4. One end of each rotating shaft 501 extends into the connecting rod 4 through a through hole, and a first threaded groove 12 is arranged at one end of each rotating shaft 501. Fixing knobs 502 are threadedly connected inside the first threaded grooves 12. The fixing knobs 502 are in contact with the connecting rod 4. When the fixing knobs 502 are not in contact with the connecting rod 4, the inclination angle of the projector body 6 can be adjusted. At the same time, by adjusting the inclination angle of the connecting rod 4 and the base 1, the projector body 6 can be stored inside the placement groove 3. The connecting rod 4 plays a supporting role for the projector body 6.

[0024] Furthermore, the height adjustment assembly includes a rotating rod 901, a connecting plate 902, a sleeve rod 903, an adjusting screw 904, and a bottom plate 905. Four storage grooves 13 are arranged in a rectangular array at the lower end of the base 1. Rotating rods 901 are rotatably installed at one side of the top ends of the four storage grooves 13. The rotating rods 901 are hingedly installed with connecting plates 902. A sleeve rod 903 is installed at one end of the connecting plate 902. A second threaded groove is arranged at the bottom end of the sleeve rod 903. Adjusting screws 904 are threadedly connected inside the second threaded groove. One end of each adjusting screw 904 extends outside the second threaded groove, and a bottom plate 905 is installed at one end of each adjusting screw 904. By rotating the sleeve rod 903 to rotate it out of the storage groove 13, and then rotating the adjusting screw 904 to adjust the combined length of the adjusting screw 904 and the sleeve rod 903, the placement height of the base 1 can be changed without using other items for support, which is convenient for use.

[0025] Furthermore, the width of the storage groove 13 is greater than the diameter of the sleeve rod 903, and the sleeve rod 903 can be completely located inside the storage groove 13, which is convenient for the base 1 to maintain a stable state when placed.

[0026] Even further, slots 14 are arranged at both ends of the base 1 below the groove 2. A protective shell 15 is placed above the base 1. Plug plates 16 are installed on both sides of the lower end of the protective shell 15. The plug plates 16 are respectively located inside the slots 14. The protective shell 15 is used to protect the stored projector body 6. The plug plates 16 are located inside the slots 14. Without the action of external force, the plug plates 16 will not accidentally slide out of the slots 14.

[0027] The usage method of this embodiment is as follows: When demonstrating the software, first remove the protective case 15, then rotate the connecting rod 4 to take out the projector body 6 from the inside of the placement groove 3. Then, adjust the combined angle of the connecting rod 4 and the base 1 and the combined angle of the connecting rod 4 and the projector body 6 respectively to adjust the projection angle of the projector body 6. Then rotate the fixing knob 502 to fix the inclination angle of the connecting rod 4. Then rotate the adjusting screw 904 to adjust the combined length of the adjusting screw 904 and the sleeve rod 903, which can change the placement height of the base 1, and thus realize the projection for the software demonstration. After the projection is completed, rotate the fixing knob 502 in the reverse direction to release the fixation of the connecting rod 4. Then rotate the connecting rod 4 to make the projector body 6 located inside the placement groove 3. Under the action of the elastic spring 10, the soft pad 11 on the push plate 8 contacts the projection lens 7 to realize the protection of the projection lens 7. Then install the protective case 15.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
