     DETAILED DESCRIPTION 
     It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the exemplary embodiments described herein. However, it will be understood by those of ordinary skill in the art that the exemplary embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the exemplary embodiments described herein. The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings, in which like references indicate similar elements. It should be noted that references to “an” or “one” exemplary embodiment in this disclosure are not necessarily to the same exemplary embodiment, and such references mean “at least one.” 
     The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like. 
       FIG. 1  illustrates a case  100  including a shell  10  and a stopping device (not labeled). The shell  10  defines a through hole  12 . The stopping device includes an elastic stopping member  40 . The stopping member  40  includes a stopping portion  42 . The stopping portion  42  is opposite to the through hole  12 . The stopping portion  42  passes though the though hole  12  and is exposed from the case  100 . The stopping portion  42  abuts an inner side of cabinet (not shown) to prevent the case  100  from sliding out of the cabinet. 
     The stopping device includes an operating member  50  and a sliding member  70  ( FIGS. 4, 6 ). The sliding member  70  includes an abutting portion  72 . The operating member  50  is rotatably fixed to the shell  10  and slidably connected to the sliding member  70 . The operating member  50  rotates in a first direction to drive the sliding member  70  to slide in a second direction and the abutting portion  72  abuts the stopping portion  42  to push portion  42  out of the through hole  12 . The operating member  50  rotates in a direction opposite to the first direction to drive the sliding member  70  to slide in a direction opposite to the second direction and the stopping portion  42  accordingly moves, to pass through and be received in the through hole  12 . 
     The shell  10  includes a front plate  14 , a first side plate  16 , and a second side plate  18 . The first side plate  16  and the second side plate  18  are connected to adjacent sides of the front plate  14 . The through hole  12  is defined on the first side plate  16 . An end of the second side plate  18  adjacent to the front plate  14  defines a first hole  11 . The operating member  50  defines a second hole  52 . A rotating shaft  60  is fixed in the first hole  11  and received in the second hole  52 . Thus, the operating member  50  can rotate around the rotating shaft  60 . 
     The operating member  50  includes a fixing portion  54 . When the operating member  50  rotates to drive the stopping portion  42  to pass through the through hole  12 , the fixing portion  54  is fixed to the front plate  14 . The fixing portion  54  defines a first fixing hole  56 . The front plate  14  defines a second fixing hole  13 . When the operating member  50  rotates to drive the stopping portion  42  to pass through the through hole  12 , the first fixing hole  56  is aligned to the second fixing hole  13 . A fixing member  62  passes through the first fixing hole  56  and is fixed in the second fixing hole  13  to fix the fixing portion  54  to the front plate  14 . The second fixing hole  13  is a threaded hole. The fixing member  62  is a bolt. 
     An end of the stopping member  40  is fixed to the first side plate  16 . The stopping member  40  includes a stopping plate  44  and a restricting plate  46  formed at an end of the stopping plate  44  away from the front plate  14 . The stopping portion  42  protrudes from the stopping plate  44 . The stopping plate  44  defines a buckle hole  48  opposite to the first side plate  16 . The restricting plate  46  defines a restricting hole  41  opposite to the front plate  14 . An end of the sliding member  70  away from the front plate  14  passes though the restricting hole  41  and is slidably disposed outside of the restricting hole  41 . The abutting portion  72  includes a wedge  74 . When the stopping portion  42  passes through the through hole  12 , the wedge  74  is latched with the buckle hole  48 . When the stopping portion  42  is pushed out of the through hole  12 , the wedge  74  separates from the buckle hole  48  and the abutting portion  72  abuts a side of the stopping plate  44  apposite to the first side plate  16 . 
     The second side plate  18  defines an arcuate restricting groove  15 . The sliding member defines a sliding groove  76 . The operating member  50  includes a restricting portion  58 . The restricting portion  58  passes through the restricting groove  15  and is slidably received in the sliding groove  76 . The restricting groove  15  is positioned at a side of the rotating shaft  60  away from the front plate  14 . The restricting groove  15  includes a first restricting end  17  adjacent to the first side plate  16  and the front plate  14  and a second restricting end  19  away from the first side plate  16  and the front plate  14 . The sliding groove  76  includes a first sliding end  78  adjacent to the first side plate  16  and a second sliding end  80  away from the first side plate  16 . The second sliding end  80  is closer than the second restricting end  19  to the front plate  14 . 
     When the operating member  50  rotates in the first direction, the restricting portion  58  slides along the restricting groove  15  from the first restricting end  17  and abuts the edge of the sliding groove  76 . The restricting portion  58  is thus driven to slide from the first sliding end  78  toward the second sliding end  80  and the sliding member  70  slides away from the front plate  14 . When the sliding member  70  slides away from the front plate  14 , the wedge  74  moves away from the front plate  14  to abut an edge of the buckle hole  48  and the stopping plate  44  moves away from the first side plate  16  to drive the stopping portion  42  out from the though hole  12 . 
     When the operating member  50  rotates in direction opposite to the first direction, the restricting portion  58  slides along the restricting groove  15  from the second restricting end  19  and abuts the edge of the sliding groove  76 . The restricting portion  58  is thus driven to slide from the second sliding end  80  toward the first sliding end  78  and the sliding member  70  slides close to the front plate  14 . When the sliding member  70  slides close to the front plate  14 , the wedge  74  moves close to the front plate  14  to lock in the buckle hole  48  and the stopping plate  44  rebounds toward first side plate  16  to drive the stopping portion  42  to be received in and pass through the though hole  12 . 
     The exemplary embodiments shown and described above are only examples. Even though numerous descriptions and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
