Through the cooperation of the metal clip and the plastic clip seat, the first shell and the second shell can be quickly assembled. After the toaster is used for a long time, due to the high temperature of the toaster during operation, the connection between the metal clip and the plastic clip seat will easily become loose due to the influence of thermal expansion and contraction. In view of the related art mentioned above, the inventor believes that a new fixed connection structure is needed to make the connection between the first shell and the second shell more stable. Utility Model Content

[0003] In order to provide a fixed connection structure capable of improving the connection stability between a first shell and a second shell, the present application provides a connection structure of a toaster shell.

[0004] The connection structure of a toaster shell provided in this application adopts the following technical solution:

[0005] A connection structure for a toaster shell includes a first shell and a second shell, the top of the first shell having a mounting portion for mounting the second shell; a plurality of metal clips are circumferentially spaced apart on the top of the mounting portion, the metal clips including a snap-on piece and a connecting portion connecting the snap-on piece and the mounting portion; the second shell is provided with a snap-on seat at the bottom of the inner wall for cooperating with the metal clip, the snap-on seat having an insertion interface cooperating with the metal clip, the snap-on seat having a snap-on strip abutting against the lower side of the snap-on piece, the snap-on strip being located on a side of the insertion interface away from the inner wall of the second shell; the snap-on piece has an abutting side wall abutting against the inner wall of the second shell.

[0006] By adopting the above technical solution, a mounting portion for installing the second shell is provided on the top of the first shell, so that the first shell and the second shell are relatively fixed in the horizontal direction; and then through the cooperation between the metal clip and the snap-fit ​​seat, the lower edge of the snap-fit ​​piece of the metal clip can abut against the snap-fit ​​strip, and the side wall of the snap-fit ​​piece abuts against the inner wall of the second shell, thereby locking the first shell and the second shell in the height direction, thereby improving the stable connection between the first shell and the second shell.

[0007] Optionally, the snap-fit ​​seat includes a snap-fit ​​plate perpendicular to the inner wall of the second shell and two reinforcing ribs respectively arranged at both ends of the snap-fit ​​plate, the reinforcing ribs are connected to the inner wall of the second shell, and the plug interface is arranged on the snap-fit ​​plate.

[0008] By adopting the above technical solution, the structure of the snap-on seat is disclosed. By providing a snap-on plate arranged perpendicular to the inner wall of the second shell and reinforcing ribs connecting the snap-on plate and the inner wall of the second shell, the snap-on seat is ensured to have reasonable structural strength, which helps to ensure a stable connection between the first shell and the second shell.
