     DETAILED DESCRIPTION 
       [0013]    The present disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
         [0014]    Referring to  FIG. 1 , an exemplary embodiment of an electronic device includes a chassis  300 , a power supply  100 , a latching member  40 , a handle  60 , and a resilient member  80 . A plurality of electronic elements (not shown), such as a motherboard and a hard disk drive, can be mounted in the chassis  300  to execute function of a computer or a server. The chassis  300  includes a bottom wall  320 , two sidewalls  322  extending up from opposite sides of the bottom wall  320 , and a top wall  321  connected between tops of the sidewalls  322  and opposite to the bottom wall  320 . The bottom wall  320 , the sidewalls  322 , and the top wall  321  cooperatively define a receiving space  323  for receiving the power supply  100  and the electronic elements. Two latching holes  324  are defined in a rear end of one of the sidewalls  322 , communicating with the receiving space  323 . 
         [0015]    The power supply  100  includes a main body  20  and a cover  23 . The main body  20  includes a rectangular frame  22  and a connector  25  formed at an end of the frame  22 . The frame  22  includes a top plate  24 , a bottom plate  26 , and two opposite side plates  28  perpendicularly connected between sides of the top plate  24  and the bottom plate  26 . Rear ends of the top plate  24 , the bottom plate  26 , and the side plates  28  cooperatively define an opening  21 . The connector  25  is exposed through the opening  21 . Two opposite tabs  242  respectively extend rearward from the rear ends of the top plate  24  and the bottom plate  26 . Each tab  242  defines a shaft hole  244 . One of the side plates  28  defines two through holes  282 . A fixing pole  284  from the side plate  28 , adjacent to the opening  21 ,fixes to the resilient member  80 . The cover  23  defines an opening  231  therein, corresponding to the connector  25 . A through hole  232  is defined in an end of the cover  23 . Two resilient pieces  234  extend rearward from the cover  23 , respectively above and below the through hole  232 . 
         [0016]    Referring to  FIG. 2 , the latching member  40  is substantially bar-shaped, and includes a resilient connecting plate  44 , a locating plate  42  slantingly extending out from a first end of the connecting plate  44 , and a guiding plate  46  slantingly extending out from a second end of the connecting plate  44 . The locating plate  42  defines two fixing holes  422 . Two wedge-shaped latching tabs  442  extend out from opposite sides of the connecting plate  44 , adjacent to the locating plate  42 . A bar-shaped protrusion  462  protrudes in from a junction of the connecting plate  44  and the guiding plate  46 . In the embodiment, the latching member  40  is made of resilient material, such as plastic or steel, and is integrally formed. 
         [0017]    The handle  60  is substantially U-shaped, and includes two parallel pivoting arms  64 , and a latching portion  62  perpendicularly connected between first ends of the pivoting arms  64 . A pin  642  extends out from a second end of each pivoting arm  64  opposite to the latching portion  62 . A guiding slot  622  is defined in a middle of an outer surface of the latching portion  62  opposite to the pivoting arms  64 . An operation portion  624  extends away from the latching portion  62  opposite to the guiding slot  622 . 
         [0018]    In the embodiment, the resilient member  80  is a spring. 
         [0019]    Referring to  FIG. 3 , in assembly of the power supply  100 , the latching member  40 , and the handle  60 , a first end of the resilient member  80  is fitted about the pole  284  of the frame  22 . Two rivets respectively extend through the fixing holes  422  of the latching member  40 , to be riveted to an outer surface of the side plate  28  defining the through holes  282 , thereby fixing the latching member  40  to an inner surface of the side plate  28 . A second end of the resilient member  80  resiliently abuts against the connecting plate  44 . The latching tabs  442  align with the corresponding through holes  282 . The protrusion  462  and the guiding plate  46  extend out of the frame  22  through the opening  21 . The cover  23  is attached to the main body  20  to cover the opening  21 . The resilient pieces  234  are exposed through the opening  21 . The guiding plate  46  and the protrusion  462  extend out through the through hole  232  of the cover  23 . The connector  25  is exposed through the opening  231 . The pins  642  of the handle  60  are rotatably inserted into the corresponding shaft holes  244 . The resilient member  80  biases the connecting plate  44  to abut a sidewall bounding the through hole  232  and adjacent to the connector  25 . 
         [0020]    Referring to  FIGS. 4-7 , in assembling the power supply  100  to the chassis  300 , the front end of the frame  22  is inserted into the receiving space  323  from the rear end of the chassis  300 . The power supply  100  is pushed forward, until the through holes  282  align with the corresponding latching holes  324 . The operation portion  624  is operated to rotate the handle  60  toward the guiding plate  46  of the latching member  40 , until the guiding plate  46  is accommodated in the guiding slot  622 . The handle  60  is rotated further, the bottom wall bounding the guiding slot  622  slidably abuts against the guiding plate  46 . The connecting plate  44  and the resilient member  80  are deformed toward the sidewall  324  defining the latching holes  324 . The latching tabs  442  are extended through the through holes  282  to engage in the corresponding latching holes  324 . After the protrusion  462  passes over the latching portion  62 , the resilient member  80  and the connecting plate  44  are restored slightly to allow the protrusion  462  latch the latching portion  62 . The handle  60  abuts against the resilient pieces  234  to deform the resilient pieces  234 . The latching portion  62  is resiliently sandwiched between the resilient pieces  234  and the protrusion  462  of the latching member  40 . 
         [0021]    In disassembling the power supply  100  from the chassis  300 , the guiding plate  46  of the latching member  40  is pressed away from the handle  60 , deforming the connecting plate  44  and the resilient member  80 , until the protrusion  462  is disengaged from the latching portion  62  of the handle  60 . The resilient pieces  234  are restored to urge the handle  60  to rotate away from the latching member  40 . The connecting plate  44  and the resilient member  80  are restored toward the connector  25 . The latching pieces  442  are disengaged from the latching holes  324 . The power supply  100  is ready to be removed from the chassis  300  through pulling the handle  60 . 
         [0022]    It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the present disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
