The second assembly columns 211 are perpendicular to the surface of the second box body 200, and a plurality of second assembly columns 211 correspond to a plurality of second through holes 220. A second assembly groove 212 is provided at the center position of the second assembly column 211, and screws are fixedly assembled with the first cover body 210 and the second box body 200 through the second through holes 220 and the second assembly groove 212.

[0038] The fixing plate 500 is arranged between the first cover body 210 and the second box body 200. The fixing plate 500 includes a fixing portion 510 and an assembly portion 520. A first storage space is formed between the first cover body 210 and the second box body 200. The fixing portion 510 is located in the first storage space. The fixing portion 510 is rectangular. A plurality of third through holes 511 are provided on the fixing portion 510. The third through holes 511 penetrate the fixing portion 510. A plurality of third assembly columns 213 are also provided on the first cover body 210. The third assembly column 213 is integrally formed with the first cover body 210. The third assembly column 213 is cylindrical. The third assembly column 213 is perpendicular to the surface of the fixing portion 510. The plurality of third assembly columns 213 correspond to the plurality of third through holes 511 one by one. A third assembly groove 214 is provided at the center position of the third assembly column 213. The screws fix and assemble the fixing portion 510 and the first cover body 210 through the third assembly groove 214 and the third through hole 511.

[0039] The assembly portion 520 is L-shaped. The assembly portion 520 is arranged on a side of the fixing portion 510 close to the undercut 400.

[0040] A blocking plate 113 is also provided on the first assembly plate 110. The blocking plate 113 is rectangular and perpendicular to the first assembly plate 110. The blocking plate 113 and the first assembly plate 110 are integrally formed. The blocking plate 113 is used to limit the displacement of the assembly portion 520 so that when the undercut 400 and the locking groove 521 are locked, the fixing plate 500 cannot shake.

[0041] In summary, the manual pressing block 300 and the undercut 400 are fixedly connected to the first box body 100, and the fixing plate 500 is fixedly connected to the second box body 200. When the suitcase needs to be locked, it is only necessary to buckle the first box body 100 and the second box body 200 so that the assembly portion 520 of the fixing plate 500 moves toward the undercut 400 until the undercut 400 enters the locking groove 521 on the assembly portion 520, and the suitcase can be locked. When the suitcase needs to be unlocked, it is only necessary to press the manual pressing block 300 so that the spring 330 is compressed, and the manual pressing block 300 drives the undercut 400 to rotate around the connecting column 310 so that the undercut 400 is out of the locking groove 521, and the suitcase can be opened at this time.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. For those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be included in the protection scope of the present application.
