One end (front end) of the base 4 is connected and fixed with the adapter member 3 through the base adapter portion 32. In the present embodiment, the base adapter portion 32 is a plurality of screw posts provided at the lower end of the adapter member 3, and the base 4 is provided with screw sleeve 41 corresponding to the screw posts, and the adapter member 3 is locked and fixed in the up-down direction by cooperating the screw posts with the screw sleeve 41 through screws. In the present embodiment, the insertion direction of the adapter member 3 with the metal inner shell 1 is the same as the insertion direction of the base 4 with the adapter member 3, that is, the insertion direction of the base 4 with the adapter member 3 is the same as the insertion direction of the adapter member 3 with the metal inner shell 1. Figure 6The X direction shown is perpendicular to the mounting direction between the connecting member 3 and the plastic housing 2 (e.g., Figure 6 (Y direction shown). That is, the insertion direction between the connecting member 3 and the metal inner shell 1 is the front-to-back direction of the barbecue grill 100, and the installation direction between the connecting member 3 and the plastic outer shell 2 is the up-down direction of the barbecue grill 100. Please refer to both. Figure 1 As shown, the barbecue grill 100 is positioned in the front-to-back, up-and-down, and left-to-right directions as follows: Figure 1 As indicated by the arrows in the diagram. This installation method of the connecting member 3 strengthens the connection between the metal inner shell 1 and the plastic outer shell 2, overcoming the problem of inconvenient installation or unreliable assembly caused by openings on the front side wall 11 of the metal inner shell 1. At the same time, this installation method also avoids fixing with screws on the front side wall 21 and the left and right side walls of the plastic outer shell 2, making the appearance of the barbecue machine 100 neat and beautiful.

[0050] Please see Figure 3 As shown, a second connecting part 221 is provided on the rear sidewall 22 of the plastic shell 2 on the side facing away from the operator. The other end (rear end) of the base 4 is connected and fixed to the plastic shell 2 through the second connecting part 221. In this embodiment, the second connecting part 221 is a screw post. Because the plastic shell 2 has the external interface 210 on the front sidewall 21, and the metal inner shell 1 is integrally fitted with the plastic shell 2, there are fewer positions on the front sidewall 21 of the plastic shell 2 where a connector can be set, and it is also necessary to avoid interfering with the installation of the metal inner shell 1. Thus, it is difficult to set a connector to the base 4 on the front sidewall 21 of the plastic shell 2. On the rear sidewall 22, since there is no opening, it is easier to set a connector. Therefore, in this embodiment of the utility model, the base 4 is connected to the connecting member 3 at the front end and to the plastic shell 2 at the rear end. Furthermore, a third connecting part 15 is provided on the bottom wall 13 of the metal inner shell 1, and the base 4 is connected and fixed to the metal inner shell 1 through the third connecting part 15. In this embodiment, the third connecting part 15 is formed by a support piece 14 disposed on the bottom wall 13 of the metal inner shell 1. Multiple support pieces 14 can be disposed on the bottom wall 13, each with connecting holes, and the base 4 can be locked to it with screws. The base 4 is connected to the connecting member 3, the metal inner shell 1, and the plastic outer shell 2, making the overall connection more stable and reliable.
