A square-section bulge 424 extends outwardly from the sides of the opening 422. A pairs of cutouts 428 is defined in the bulge 424 in a direction parallel to the side walls 44. A hook 442 extends outwardly from the side of each of the side walls 44, corresponding to the aperture 322 of the base member 30. A tab 462 extends from the side of one of the side wall 46 corresponding to the position hole 323 of the base member 30.
The latch 50 is a standard component and comprises a housing 52 and a locking portion 54 elastically received in the housing 52. The housing 52 comprises a top portion and a bottom portion. A length of the bottom portion (not labeled) is greater than that of the top portion (not labeled). A pair of protrusions 522 corresponding to the cutout 428 of the intermediate member 40 protrudes from two opposite sides of the top portion of the housing 52 adjacent the bottom portion. The locking portion 54 has two claws 542. When the locking portion 54 slides into the housing 52, the claws 542 are closed. When the locking portion 54 extends out from the housing 52, the claws 542 are opened.
The foot 60 comprises a base 62 and a pole 64 extending perpendicular from the base 62. A supporting portion 622 is arranged at the base 62 adjacent the pole 64 corresponding to the opening 344 of the base member 30. The pole 64 comprises a first column portion 642 and a second column portion 644 extending outwardly from the first column 642. A diameter of the first column portion 642 is greater than the maximal diameter of the through hole 324 of the base member 30, but smaller than that of the through hole 342 of the base member 30. A diameter of the second column 644 is smaller than the minimal diameter of the through 324 of the base member 30. A ringed groove 645 is defined in an outer surface of the second column portion 644 for receiving a gasket 66.
