[0017] To achieve the above technical solution, the arc-shaped transition section is designed to facilitate the insertion of the lampshade into the tool housing. At the same time, the arc-shaped transition section and the arc-shaped guide section are designed in conjunction to decompose part of the clamping force of the retaining spring on the lampshade into a circumferential thrust, so that the lampshade is pressed tightly on the annular positioning platform, thereby further improving the installation stability of the entire lampshade.

[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. First, place the lamp ring in the lamp ring, then put the lamp cover on the tool housing, so that the annular positioning table is inserted into the positioning groove, thereby achieving the positioning and fixing of the lamp cover. Then, the lamp cover is locked and fixed by the positioning component, which facilitates the assembly by personnel. 2. The arc-shaped transition section facilitates the insertion of the lampshade into the tool housing. At the same time, the arc-shaped transition section and the arc-shaped guide section are designed to decompose part of the clamping force of the retaining spring on the lampshade into a circumferential thrust, so that the lampshade is pressed tightly on the annular positioning platform, thereby further improving the installation stability of the entire lampshade.
