Specifically, referring to fig. 3, the mounting body 210 includes a body 213 and a plurality of clamping seats 211 disposed on the body 213, the clamping seats 211 are independently disposed and protrude from the light source 220 in the same direction, so that the lamp shade 100 is mounted on the lamp body 200 by disposing the clamping seats 211 on the body 213 for being clamped with the clamping jaws 112 one by one.

Specifically, referring to fig. 6, the card seat 211 extends in the length direction of the seat body 111, and includes a first side plate 2111 and a second side plate 2112 which are oppositely disposed, a first connecting plate 2113 connected between one end of the first side plate 2111 and one end of the second side plate 2112, and a second connecting plate 2114 connected between the other end of the first side plate 2111 and the other end of the second side plate 2112, wherein the first side plate 2111, the second side plate 2112, and the second connecting plate 2114 all protrude in the same direction as the light source 220, i.e., all protrude in the axial direction of the body 213, and the first connecting plate 2113 and the end surface of the body 213 are disposed in parallel.

It can be understood that, in order to clamp the clamping jaws 112 on the clamping seat 211, the notch 212 is disposed on the clamping seat 211, and an accommodating space is formed in the clamping seat 211 for accommodating the clamping jaws 112, when the lamp shade 100 is installed on the installation body 210, one clamping jaw 112 is correspondingly clamped in one clamping seat 211 after penetrating through one notch 212, so as to implement the installation of the lamp shade 100.

The projected area of the end surface of the elastic abutting table 250 to the mounting body 210 is larger than the projected area of the end surface of the elastic ejector pin 240 to the mounting body 210. When the clamping jaws 112 are clamped in the clamping seat 211, the clamping jaws abut against the elastic abutting table 250, and the elastic abutting table 250 applies a reverse acting force to the clamping jaws 112, so that the installation stability of the clamping jaws 112 is increased, that is, the installation stability of the lampshade 100 is increased. After the clamping jaw 112 penetrates the notch 212, the clamping jaw 112 abuts against the elastic abutting table 250 through rotating and being clamped in the clamping seat 211, so that the clamping jaw 112 is pressed in the clamping seat 211 through the elastic force of the elastic ejector pin 240 which is restored to the original state.
