[0040] The connecting end 251 has a first side surface 253 and a second side surface 254 arranged adjacent to each other. The first side surface 2513 is the end face of the connecting end 251 away from the holding end 252, and the second side surface 2514 is connected to the first side surface 2513 through an arc surface 2515. The bottom wall of the groove 211 contacts the first side surface 2513 when the handle 25 swings to the sealed state and contacts the second side surface 2514 when the handle 25 swings to the open state, enabling the bottom wall of the groove 211 to support and limit the connecting end 251 of the handle during the swinging process of the handle to maintain the state of the second cover body 22. The distance between the first rotating shaft 2511 and the first side surface 2513 is greater than the distance between the first rotating shaft 2511 and the second side surface 2514, so as to support the first rotating shaft 2511 at different heights in the open state and the closed state, and further enable the first rotating shaft 2511 to drive the connecting arm 243 and the second cover body 22 to move up and down. The arc surface 2515 is used for the transition between the first side surface 2513 and the second side surface 2514, so that the bottom wall of the groove 211 and the connecting end 251 of the handle always remain in contact during the swinging process of the handle 25.

[0041] The second rotating shaft 2512 is arranged at the end of the connecting end 251 away from the holding end 252 and the arc surface 2515 is flush with the outer surface of the second rotating shaft 2512.

The upper side of the second rotating shaft 2512 can contact the top wall of the sliding groove 211, and the lower side of the second rotating shaft 2512 contacts the bottom wall of the groove 211, enabling the second rotating shaft 2512, the first side surface 2513, the second side surface 2514 and the arc surface 2515 to act on the bottom wall of the groove 211 together, making the connection more stable. The first wall plate 2112 and the second wall plate 2115 are respectively arranged at both ends of the bottom plate 2113 in the length direction. When the handle 25 is in the open state, the holding end 252 is arranged at one end of the connecting end 251 close to the first wall plate 2115. The sliding groove 21161 is arranged on the third wall plate 2116 along the length direction of the bottom plate 2113. One end of the sliding groove 21161 is arranged close to the first wall plate 2112, and the other end is arranged close to the second wall plate 2115, and the distance between the sliding groove 21161 and the first wall plate 2112 is greater than the distance between the sliding groove 21161 and the second wall plate 2115. The second channel opening 2114 is arranged on the first cover body 21 along the length direction of the bottom plate 2113. One end of the second channel opening 2114 is arranged close to the first wall plate 2112, and the other end is arranged close to the second wall plate 2115, and the distance between the second channel opening 2114 and the first wall plate 2112 is less than the distance between the second channel opening 2114 and the second wall plate 2115. In this embodiment, the handle 25 can be limited in the open state and the closed state, and at the same time, sufficient movement space is provided for the swinging of the connecting end 251 of the handle 25 in the groove 211.

[0042] Reference Figure 4, a connection groove 2516 is formed in the connection end 251 from the first side surface 2513 towards the direction close to the holding end 252. The connection arm 243 is inserted into the connection groove 2516. Both sides of the connection groove 2516 penetrate through the connection end 251 to facilitate the rotation of the connection arm 243 therein. A first shaft hole 2431 for the first rotating shaft 2511 to pass through is formed through the upper end of the connection arm 243. Shaft holes 2517 for the first rotating shaft 2511 to pass through are respectively formed through both side walls of the connection groove 2516. The connection between the handle connection end 251 and the connection arm 243 of the connection seat 24 is realized by inserting the first rotating shaft 2511 into the first shaft hole 2431 and the shaft holes 2517. During installation, the first rotating shaft 2511 can be loaded and unloaded through the third channel opening 2117. The second rotating shaft 2512 protrudes outwards from the side wall of the connection groove 2516 close to the third wall plate 2116, with a stable and firm structure. The sliding groove 21161 is arranged on the third wall plate 2116 corresponding to the second rotating shaft 2512.
