The outer diameter of the main body portion of the first limiting pin 3, which is correspondingly located between the first blocking edge 31 and the second blocking edge 32, is matched with the groove width of the first limiting groove 121 and the groove width of the first guiding groove 211. The first end of the first limiting groove 121 has a first mounting opening 1210, and the inner diameter of the first mounting opening 1210 is larger than the groove widths of the first limiting groove 121 and the first guide groove 211. More specifically, the inner diameter of the first mounting hole 1210 is larger than the outer diameter of the second blocking edge 32 of the first limiting pin 3 and smaller than the outer diameter of the first blocking edge 31, so that the first mounting hole 1210 can be used for the second blocking edge 32 of the first limiting pin 3 to pass downwards to limit the first blocking edge 31. Likewise, the second stop pin 4 of the present embodiment has a third stop edge 41 extending radially outward at an upper end and a fourth stop edge 42 extending radially outward at a lower end, wherein the third stop edge 41 has an outer diameter larger than that of the fourth stop edge 42. The outer diameter of the main body portion of the second limiting pin 4 between the third blocking edge 41 and the fourth blocking edge 42 is matched with the groove width of the second limiting groove 122 and the groove width of the second guiding groove 221. The first end of the second limiting groove 122 has a second mounting opening 1221, and the second mounting opening 1221 has an inner diameter larger than the groove widths of the second limiting groove 122 and the second guide groove 221. More specifically, the second mounting opening 1221 has an inner diameter larger than the outer diameter of the fourth stop edge 42 of the second stopper pin 4 and smaller than the outer diameter of the third stop edge 41, thereby allowing the second mounting opening 1221 to pass through the fourth stop edge 42 of the second stopper pin 4 downward while restricting the third stop edge 41.

The bottom wall of the first sinking platform 12a of the top plate 12 of the casing 10 has a first concave region 1211 formed by being downwardly recessed at a position corresponding to the second end of the first limit groove 121, and the shape of the first concave region 1211 is adapted to the shape of the first blocking edge 31 of the first limit pin 3, so that the first blocking edge 31 thereof can be restricted in the second concave region 1220 without being easily removed when the first limit pin 3 moves to the second end position of the first limit groove 121. Likewise, the bottom wall of the second sinking platform 12b of the top plate 12 of the casing 10 has a second concave area 1220 formed by being recessed downward at a position corresponding to the second end of the second limit groove 122, and the shape of the second concave area 1220 is adapted to the shape of the third blocking edge 41 of the second limit pin 4, so that the third blocking edge 41 thereof can be restricted in the second concave area 1220 without being easily removed when the second limit pin 4 moves to the second end position of the second limit groove 122. The design of the first concave area 1211 and the second concave area 1220 prevents the first limiting pin 3 and the second limiting pin 4 from shifting the locking positions along the extending direction of the corresponding limiting groove in the operation process of the range hood, thereby further ensuring the installation reliability of the range hood.

The first guide groove 211 of the first support plate 21 has a third mounting hole 2110 at a position corresponding to the first mounting hole 1210 of the first limiting groove 121, and the size of the third mounting hole 2110 is substantially identical to the size of the first mounting hole 1210.
