     DETAILED DESCRIPTIONS 
     The embodiments of the present disclosure provide many different embodiments or examples used to implement different features of the embodiments of the present disclosure. The following describes specific examples of components and arrangements to simplify the embodiments of the present disclosure. Certainly, these are only examples and are not for limitation purposes. For example, in the following descriptions, that a first feature is formed above or on a second feature may include an embodiment in which the first feature and the second feature that are in direct contact are formed, and may also include an embodiment in which an extra feature may be formed between the first feature and the second feature so that the first feature and the second feature may be not in direct contact. In addition, in the embodiments of the present disclosure, reference numerals and/or signs of components may be repeated in various examples. This repetition is for simplification and clarity purposes and does not indicate a relationship between various discussed embodiments and/or configurations. 
     In addition, for ease of description, relative spatial terms (for example, “top”, “bottom”, “below”, “under”, “lower”, “upper”, “above”, and similar terms) may be used to describe a relationship between a component or a feature and another (several) component or another (several) feature in this specification, as shown in the figures. Relative spatial terms further intend to cover different orientations in usage or operation of the apparatus in addition to orientations shown in the figures. A device may use other orientations (rotate by 90 degrees or according to another orientation) and relative spatial description terms used in this specification may be further interpreted on this basis. 
     Terms “approximately”, “generally”, “substantially”, and “about” used in this specification are used to describe small changes. When the terms are used in combination with events or cases, the terms may indicate precise examples of the events or cases and extremely similar examples of the events or cases. For example, when the terms are used in combination with values, the terms may indicate a change range less than or equal to ±10% of the values, for example, less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, if a difference between two values is less than or equal to ±10% of an average value of the values, (for example, less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%), it may be considered that the two values are “approximately” the same. 
     In addition, amounts, ratios, and other values are sometimes indicated in a form of a range in this specification. It should be understood that the form of the range is used for convenience and simple purposes and shall be flexibly understood, and includes not only values clearly specified as falling within the range but also all individual values or sub-ranges falling within the range similar to each clearly specified value and sub-range. 
     In addition, for ease of description, “first”, “second”, “third”, and the like may be used to distinguish different components in one figure or a series of figures in this specification. “First”, “second”, “third”, and the like are not intended to describe corresponding components.

     According to another embodiment of the present disclosure, the first support  101 , the second support  103 , and the third support  105  are formed in one-piece by using metal material or non-metal material. 
     According to an implementation of the present disclosure, referring to  FIG. 1  and  FIG. 3 , the fixing apparatus  100  may further comprise a slot  109  defined by the first support  101 , the second support  103 , and the third support  105 . As shown in  FIG. 3 , when the fixing apparatus  100  is at the fixed position, the slot  109  may expose an identifier or an image  203  on the wireless charger  200 . 
     In the embodiments of the present disclosure, the elastic component may be any apparatus that can enable the fixing apparatus to move between the initial position and the fixed position, for example, but not limited to, a spring, a torsion spring, an elastic wire, an elastic cord, or an elastic band, etc. According to an embodiment of the present disclosure, the elastic component  107  may be two torsion springs. Referring to  FIG. 1  and  FIG. 4 , the two torsion springs are connected to the first support  101  and the second support  103  respectively. The two torsion springs are configured to enable the fixing apparatus  100  to move between the initial position and the fixed position. The first ends  107   a  of the two torsion springs are configured to respectively be connected to an end portion of the first support  101  and an end portion of the second support  103 , and the second ends  107   b  of the two torsion springs  107   a  are configured to be connected to the base  201  of the wireless charger  200 . 
     When a user needs to fix the mobile device to the wireless charger  200 , the user may hold the protrusion component  101   b  and the protrusion component  103   b , and rotate the fixing apparatus  100  counterclockwise. After the elastic component  107  rotates counterclockwise more than about 180 degrees from the initial position shown in  FIG. 2 , the elastic component  107  may automatically continue to rotate counterclockwise without holding by the user, until the mobile device is fixed to the wireless charger  200 . 
     The fixing apparatus  100  of the embodiments of the present disclosure is applicable to mobile devices having various different thicknesses. For example, when the fixing apparatus  100  rotates counterclockwise about 260 degrees, the mobile device having a corresponding thickness may be fixed to the wireless charger  200 . Alternatively, when the fixing apparatus  100  rotates counterclockwise about 290 degrees, the mobile device having a corresponding thickness may be fixed to the wireless charger  200 . Generally, when the fixing apparatus  100  rotates counterclockwise about 260 to 290 degrees, the mobile devices having different corresponding thicknesses may be fixed to the wireless charger  200 . Alternatively, when the mobile device is not placed on the wireless charger  200  in advance, after rotating counterclockwise more than about 180 degrees from the initial position shown in  FIG. 2 , the fixing apparatus  100  may directly stick with the wireless charger  200  automatically without damaging the wireless charger  200 . 
     When a user needs to remove the mobile device from the wireless charger  200 , the user only needs to clockwise pull the protrusion component  101   b  and the protrusion component  103   b , the mobile device is easily removed. In addition, when a user clockwise rotates the fixing apparatus  100  to a position approximately lower than a horizontal plane, the fixing apparatus  100  will automatically returns to the initial position shown in  FIG. 2 . 
     As shown in  FIG. 4 , the fixing apparatus  100  is configured to be fixed to the base  201  of the wireless charger  200  in insertion manner. In other embodiments of the present disclosure, the fixing apparatus  100  may also be fixed to the base  201  of the wireless charger  200  by fastening with a fastening component common in the art or in other common fixing manners. 
     The fixing apparatus of the wireless charger  100  provided in the embodiments of the present disclosure can stably fix the mobile devices having different thicknesses to the wireless charger without damaging the surface of the mobile device. In addition, support portions of the fixing apparatus  100  of the wireless charger provided in the embodiments of the present disclosure may be made of any metal or non-metal material, and have advantages of simple structures, low costs, and easy production. Moreover, when a user needs to fix the mobile device to the fixing apparatus  100 , the user only needs to rotate counterclockwise the fixing apparatus  100 , the mobile device can be to stably fixed. When the user needs to remove the mobile device from the fixing apparatus  100 , the user only needs to rotate clockwise the fixing apparatus  100 , the mobile device can be easily removed, and the fixing apparatus  100  will not cause any damage the mobile device.
