BACKGROUND 
     1. Technical Field 
     The present disclosure relates to mounting apparatuses, and particularly to a mounting apparatus to secure a fan module to an electronic device chassis. 
     2. Description of Related Art 
     In a working computer system, a large amount of heat is generated from various electric elements of the computer system. If the heat is not dissipated in a timely manner, the electric elements may be damaged. Therefore, heat-dissipating devices are required in most computer systems. 
     A fan module is often used to dissipate heat from the computer system. A chassis may be provided for mounting a fan module. A plurality of through holes may be defined in the chassis. The fan module may define a plurality of screw holes. The through holes of the chassis are aligned with the screw holes of the fan module. A plurality of screws extends through the through holes to screw into the screw holes. The fan is thereby secured to the chassis of the computer system. However, the screw mounting means in assembly and disassembly of the fans is very labor-intensive and inconvenient. 
     Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
     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” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
     Referring to  FIG. 2 , a mounting apparatus in accordance with an embodiment comprises a chassis  10 , an installation member  30 , and two mounting members  50  secured to the chassis  10 . The mounting apparatus is configured for securing a fan module  70  to the chassis  10 . The fan module  70  comprises a plurality of fans  71 , and a bracket  73  for receiving the plurality of fans  71 . Two pivot portions  731  are placed on two opposite sides of the bracket  73 . 
     The chassis  10  comprises two sidewalls  11  parallel to each other, and a bottom board  13  connected to the two sidewalls  11 . A folding edge  111  extends inwardly from each of the two sidewalls  11 . The folding edge  111  defines a cutout or a gap  113 . Two installation pieces  115  substantially parallel to each other, extend from each of the two sidewalls  11  and are located on opposite sides of the gap  113 . Each of the two installation pieces  115  defines an installation hole  1151 . In one embodiment, each of the two installation pieces  115  is substantially perpendicular to each of the two sidewalls  11 . 
     The installation member  30  comprises an installation board  31  and two pivot pieces  33 . The two pivot pieces  33  extend from two opposite ends of the installation board  31 . Each of the two pivot pieces  33  defines a pivot hole  331 . The pivot hole  331  comprises a wide portion  3311  and a narrow portion  3313  communicating with the wide portion  3311 . 
     Referring to  FIG. 3 , each of two mounting members  50  comprises a connecting board  51 , two clipping portions  53  located on two opposite sides of the connecting board  51 , a pulling portion  55  extending from the connecting board  51 , and a extending portion  57 . In one embodiment, the two clipping portions  53 , the pulling portion  55  and the extending portion  57  are arranged at the four sides of the connecting board  51 . 
     A limiting portion  511  is located on the connecting board  51 , and the limiting portion  511  comprises a neck portion  5111  extending from connecting board  51 , and a head portion  5113  extending from the neck portion  5111 . In one embodiment, a diameter of the neck portion  5111  is smaller than that of the head portion  5113 . An abutting piece  513  is located on the connecting board  51 , and is opposite to the limiting portion  511 . The abutting piece  513  is adapted to absorb vibration. 
     Each of the two clipping portions  53  comprises a connecting portion  531  extending from the connecting board  51 , a converting portion  533  extending from the connecting portion  531 , and a gripping portion  535  extending from the converting portion  533 . In one embodiment, the connecting portion  531  is substantially perpendicular to the connecting board  51 , the converting portion  533  is substantially perpendicular to the connecting portion  531  and parallel to the connecting board  51 , and the gripping portion  535  is substantially perpendicular to the converting portion  533  and the connecting board  51 . A guiding portion  5351  extends upward from gripping portion  535 . 
     An end of the pulling portion  55  forms a rotating portion  551 , and a mounting hole  5511  is defined in the rotating portion  551 . In one embodiment, an obtuse angle is defined between the pulling portion  55  and the connecting board  51 . 
     The extending portion  57  comprises a bent portion  571  extending from the connecting board  51 , and a leaning portion  573 . In one embodiment, the bent portion  571  is substantially perpendicular to the connecting board  51  and the leaning portion  573  is substantially perpendicular to the bent portion  571 . Two holding portions  5731  are located on two opposite sides of the leaning portion  573 . In one embodiment, each of the two holding portions  5731  is substantially perpendicular to the leaning portion  573 . 
     Referring to  FIGS. 1 and 4 , in assembly, the rotating member  551  of one of the two mounting members  50  is placed in the gap  113  of the chassis  10 , the abutting piece  513  abuts the corresponding one of the two sidewalls  11 . Two opposite ends of the mounting hole  5511  are aligned with two installation holes  1151 , and the locking member  80  extends through one of the two installation holes  1151 , the mounting hole  5511  and another of the two installation holes  115  to pivotably secure one of the two mounting members  50  to one of the two sidewalls  11 . Another one of the two mounting members  50  is pivotably secured to another one of the two sidewalls  11  in the same manner. 
     In assembly, the installation board  31  is put up in a third direction (shown in  FIG. 5 ). Each of the two pivot pieces  33  is adaptor to be rotated along the two pivot portions  731 , until the pivot hole  331  aligns with the neck portion  5111  of each of the two mounting members  50 . The fan module  70  descends along the guiding portion  5351  of the gripping portion  535 . The neck portion  5111  extends through the wide portion  3311  of the pivot hole  331 , until the neck portion  5111  engages in the narrow portion  3313 . The installation board  31  is rotated in a fourth direction opposite to the third direction, until each of the two pivot pieces  33  engages with the bracket  73 . Thereby, the fan module  70  is engaged between the two mounting members  50  to prevent from the fan module from moving in a first direction substantially perpendicularly to the two sidewalls  11 , and in a plane which is substantially parallel with the two sidewalls  11 . The neck portion  5111  is engaged in the narrow portion  3313  to prevent the fan module  70  from moving in a second direction substantially perpendicularly to the first direction and the plane. Each of the two pivot pieces  33  is located between the connecting board  51  and the bracket  73 . The bracket  73  is clipped between two the gripping portions  535  and the two holding portions  5731 , and the leaning portion  573  abuts the adjacent side of the bracket  73 . In this way, the fan module  70  is secured to the chassis. 
     In disassembly, the installation board  31  is put up to rotate each of the two pivot pieces  33  along the third direction, until the pivot hole  331  aligns with the bottom board  13  of the chassis  10 . The fan module  70  is moved away from the chassis  10 . The neck portion  5111  is moved from the narrow portion  3313  to the wide portion  3311 . Thus, the fan module  70  can be removed from the chassis  10 . 
     It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
