However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application, therefore, the present application is not limited by the specific embodiments disclosed below.

[0032] Referring to Figures 1-12 A drawer rear part dismounting module, comprising a connecting piece 1 arranged on the rear part of the drawer, further comprising a positioning piece 3 for assembling a drawer rear part accessory 2, a buckling assembly with an unlocking state and a buckling state is arranged between the connecting piece 1 and the positioning piece 3, the drawer rear part accessory 2 is connected with the positioning piece 3, and the positioning piece 3 of the drawer rear part accessory 2 is dismounted on the connecting piece 1 through the buckling assembly.

[0033] By arranging the drawer rear part accessory 2 on the rear part of the drawer, the heightening structure of the drawer side plate is adapted, and the drawer rear part accessory 2 is arranged with the positioning piece 3 dismountable on the connecting piece 1, the connecting piece 1 is connected with the side plate 12 of the drawer, thereby realizing the dismounting structure between the drawer rear part accessory 2 and the side plate 12, and facilitating the user to install the corresponding drawer rear part accessory 2 according to the heightening structure of the drawer side plate 12, and meeting the use requirements of different users. In addition, the drawer back plate can also not be designed as an integral plate body, and the drawer rear part accessory 2 and the plate body located at the bottom of the drawer rear part accessory 2 are used as the drawer back plate, so that the production material cost of the drawer back plate can be appropriately reduced.

[0034] The buckling assembly comprises a lock-off buckling part 4, the lock-off buckling part 4 is arranged with a guide block 5, and the positioning piece 3 is directionally dismounted on the connecting piece 1 through the guide block 5 of the lock-off buckling part 4.

[0035] In the embodiment, the connecting piece 1 is arranged with an assembling part 7 corresponding to the guide block 5 and the lock-off buckling part 4, when the positioning piece 3 is connected with the connecting piece 1, the guide block 5 plays a role of directionally inserting into the assembling part 7, and after the guide block 5 is inserted into the assembling part 7, the guide block 5 is limited up and down in the assembling part 7.
