The second opening 54 can be provided for the cable 41 to pass through, so that the cable 41 can smoothly enter the shell 1, and meanwhile, the second opening 54 is blocked by the anti-pulling buckle 42, so that the flame inside the shell 1 is prevented from channeling upwards, and the lamp is ensured to have the required fireproof performance.

The elastic fixture block 422 is provided with a guide inclined plane, when the anti-pull buckle 42 is inserted into the second opening 54, the guide inclined plane is pressed inwards by the edge of the second opening 54, and the elastic fixture block 422 is retracted so as to pass through the second opening 54; after the anti-pulling buckle 42 passes through the second opening 54, the elastic fixture block 422 resets under the elasticity of the elastic fixture block 422, the convex block on the elastic fixture block 422 is contacted with the lower surface of the bottom plate 5, and the second cover plate 421 is contacted with the upper surface of the bottom plate 5, so that the anti-pulling buckle 42 is clamped in the second opening 54, and meanwhile, the second opening 54 is blocked by the second cover plate 421, and the requirement of the fireproof performance of the lamp is met; the anti-pulling buckle 42 is firmly connected with the bottom plate 5, so that the anti-pulling buckle 42 is prevented from being pulled out of the second opening 54 when the cable 41 is pulled accidentally. Specifically, the anti-pulling buckle 42 is also made of fireproof material.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
