The fixing frame 5, the projection sheet 6 and the slide 7 together constitute a projection component, or the projection sheet 6 is defined as a projection component, or the projection sheet 6 and the slide 7 are defined as a projection component. The projection sheet 6 forms a fan-shaped structure in the unfolded state, and is installed in the installation hole 511 to form a hollow conical structure, and its taper is the same as the taper of the inner wall of the installation hole 511. The projection sheet 6 is installed upward in the installation hole 511, and the fit between the projection sheet 6 and the inner wall of the installation hole 511 is changed from loose fit to tight fit. The projection sheet 6 is attached to the inner wall of the installation hole 511 to prevent the projection sheet 6 from automatically falling off the fixing frame 5. The projection sheet 6 includes a transparent film, a main projection area arranged on the transparent film, and an auxiliary projection area arranged around the main projection area. The transparent film serves as the negative film of the projection sheet 6, and the main projection area includes a monochrome area and / or a multi-color area and / or a transparent area.

The second end 62 includes a matching portion 621 and at least one locking portion 622 arranged away from the plug-in portion 612 relative to the matching portion 621. In this embodiment, the two plug-in portions 612 are arranged at intervals in the up and down directions, and the two plug-in portions 612 are buckled with the two locking portions 622 in a one-to-one correspondence. The base 611 and the matching portion 621 are stacked up and down, and the base 611 is located above the matching portion 621, and the overlapping area of ​​the base 611 and the matching portion 621 gradually decreases from bottom to top. The width of the plug-in portion 612 is less than 1 / 2 of the width of the base portion 611. The locking portion 622 is configured as a snap groove penetrating the matching portion 621. The width of the snap groove is less than 1 / 2 of the width of the second end portion 62. The plug-in portion 612 is inserted into the snap groove. The plug-in portion 612 protrudes into the inner side of the tapered projection film 6 or is exposed on the outer side of the projection film 6. The distances between the two snap grooves and the edge of the matching portion 621 are the same or the distance between one of the snap grooves and the edge of the matching portion 621 is greater than the distance between the other snap groove and the edge of the matching portion 621. The first end face of the first end portion 61 and / or the second end face of the second end portion 62 are inclined toward the central axis P of the tapered projection film 6.
