[0020] Even further, the telescopic rod is composed of a sleeve 401 and a sleeve rod 402 slidably sleeved on its inner wall. A screw 404 is installed at the connection between the sleeve 401 and the sleeve rod 402. Multiple first slots 403 are provided on the outer peripheral surface of the sleeve rod 402. The screw 404 is inserted into the first slots 403. The screw 404 is threadedly connected to the sleeve 401. The sleeve 401 is fixedly connected to the first mounting seat 4, and the sleeve rod 402 is fixedly connected to the second mounting seat 405.

[0021] Further, the first disassembly and assembly component includes a connecting seat 3, a positioning plate 301, an adjusting rod 5, an abutting plate 502, and an elastic member 503; the connecting seat 3 is connected to the second mounting seat 405 by bolts, and the connecting seat 3 is U-shaped; there are two groups of positioning plates 301, and the two groups of positioning plates 301 are symmetrically installed on the connecting seat 3. A second jack 302 is provided on the positioning plate 301, and the second jack 302 is a square hole. The second disassembly and assembly component is slidably connected between the two groups of positioning plates 301; there are two groups of adjusting rods 5, and the cross-section of the adjusting rod 5 is square to prevent rotation when the L-shaped seat 2 is connected to the adjusting rod 5. The adjusting rod 5 slidably penetrates the end of the connecting seat 3, and a handle 501 is installed at one end of the adjusting rod 5. The other end of the adjusting rod 5 slidably penetrates the second jack 302 on the positioning plate 301; the abutting plate 502 is installed on the adjusting rod 5, and the abutting plate 502 abuts against the positioning plate 301; the elastic member 503 is installed on the abutting plate 502, and the other end of the elastic member 503 is connected to the end of the adjacent connecting seat 3. The elastic member 503 is a spring, and the elastic member 503 is movably sleeved outside the adjusting rod 5.

[0022] Further, the second disassembly and assembly component is composed of an L-shaped seat 2. The bottom end of the L-shaped seat 2 is connected to the projection device 1 by bolts. A first jack 201 is provided on the L-shaped seat 2, and the first jack 201 is a square hole. The first jack 201 corresponds to the second jack 302, and the two groups of L-shaped seats 2 are slidably connected between the two groups of positioning plates 301.

[0023] In this embodiment, the second mounting base 405 is connected to the connecting base 3 in the first disassembly and assembly component through bolts. The first mounting base 4 is fixedly connected to a suitable position on the roof through bolts. The sleeve rod 402 slides up and down along the inner wall of the sleeve 401 to a suitable position, and the screw rod 404 is rotated until it is inserted into the corresponding slot 403. Thus, the overall length of the telescopic rod can be adjusted, and then the first adjustment component is driven to adjust the height, and then the projection device 1 is driven to adjust the installation height. The two L-shaped seats 2 are installed at suitable positions on the top of the projection device 1 through bolts. Hold the two handles 501 and pull the corresponding adjusting rod 5 outward along the connecting base 3 until the inserted end of the adjusting rod 5 contracts into the second jack 302. At this time, the abutting plate 502 is away from the positioning plate 301, and the elastic member 503 is compressed. Slide the two L-shaped seats 2 along between the two positioning plates 301 until the first jack 201 is aligned with the second jack 302. Thus, the second disassembly and assembly component can be quickly aligned with the first disassembly and assembly component. At this time, release the handle 501. Under the action of the elastic recovery of the elastic member 503, the adjusting rod 5 is driven to slide outward toward the outside of the second jack 302 until the abutting plate 502 abuts against the positioning plate 301. At this time, the adjusting rod 5 slides along the second jack 302 toward the first jack 201 and is inserted until it penetrates the first jack 201. Thus, the second disassembly and assembly component is quickly connected to the first disassembly and assembly component. According to the same operation, the inserted end of the adjusting rod 5 is retracted into the second jack 302, and the L-shaped seat 2 can be separated from the positioning plate 301 to complete disassembly and assembly. Thus, the projection device 1 is convenient for quick disassembly and assembly;

[0024] When the projection device 1 needs to be installed on the wall, the first mounting base 4 is installed on the wall through bolts, and then the overall length of the sleeve 401 and the sleeve rod 402 is adjusted. At this time, the main seat is perpendicular to the wall. Slide the two L-shaped seats 2 along between the two positioning plates 301 until the first jack 201 is aligned with the second jack 302. By adjusting the adjusting rod 5, the L-shaped seat 2 can be quickly connected to the connecting base 3. At this time, the L-shaped seat 2 is perpendicular to the connecting base 3. The settings of the adjusting rod 5, the second jack 302, and the first jack 201 can effectively prevent the L-shaped seat 2 from rotating along the adjusting rod 5 and interfering with the installation stability of the projection device 1. The disassembly and assembly are convenient and fast, and multiple installation methods can be provided, with higher practicability.

[0025] Embodiment 2

A U-shaped rod 504 is inserted between the two third jacks 505. Nuts are threadedly connected to both ends of the U-shaped rod 504, and the nuts abut against the adjusting rods 5.

[0027] In this embodiment, the U-shaped rod 504 is aligned with the two groups of third jacks 505 and inserted, so that the U-shaped rod 504 is inserted between the two groups of adjusting rods 5. Then, a nut is threadedly connected to the end of the U-shaped rod 504 until the nut abuts against the adjusting rod 5, thereby limiting the two groups of adjusting rods 5 relative to the connecting seat 3, preventing the adjusting rod 5 from sliding easily and causing the projection device 1 to fall, and improving the installation safety.
