The second elastic member  150  is disposed between the upper machine body  120  and the battery casing  110 . In this embodiment, the second elastic member  150  may be a pogo pin, but the types of the first elastic member  130  and the second elastic member  150  are not limited thereto. 
     The lower casing body  160  is fixed on the upper machine body  120 , and the battery casing  110  is located between the upper machine body  120  and the lower casing body  160 . In the embodiment, the battery casing  110  is pivoted to the upper machine body  120 ; therefore the battery casing  110  may rotate relative to the upper machine body  120  and the lower casing body  160 . The material of the upper machine body  120  and the lower casing body  160  may be metal, so as to provide a more preferable appearance quality to the wearable device  100 , and the material of the battery casing  110  may be plastic, so as to reduce the weight of the wearable device  100 . Certainly, the materials of the battery casing  110 , the upper machine body  120  and the lower casing body  160  are not limited thereto. 
     In addition, in the embodiment, the door  170  is pivoted to the battery casing  110 , so as to shield portions of the side surfaces of the upper machine body  120  and the battery casing  110 , in order to achieve the effect of hiding ugliness and complete the exterior appearance of the wearable device  100 . According to other embodiments, the door  170  may also be pivoted to the upper machine body  120 . 
     In the embodiment, the first belt structure  180  and the second belt structure  190  are watch bands, wherein the first belt structure  180  is pivoted to the battery casing  110 , the second belt structure  190  is pivoted to a lower position of the side surface of the upper machine body  120 , such that the first belt structure  180  and the second belt structure  190  may be able to be located at the same plane. 
     Through the abovementioned structure, the wearable device  100  of the embodiment may achieve the effect that the battery  10  may be easily replaced, and the detailed description is illustrated as follows.  FIG. 2  through  FIG. 7  are schematic flow diagrams illustrating a process of replacing battery of the wearable device as depicted in  FIG. 1 . First, referring to  FIG. 1  and  FIG. 2  together, under normal situation, the battery casing  110  is in the first position P 1  relative to the upper machine body  120 , namely the upper machine body  120  is overlapped with the battery casing  110 . In this situation, since the upper machine body  120  covers the battery casing  110 , the battery accommodating space  112  within the battery casing  110  may be shielded by the upper machine body  120 . The hook  142  is movably fixed to the engaged member  114  of the battery casing  110 , and the relative positions between the battery casing  110  and the upper machine body  120  are fixed. If the battery  10  is to be replaced, first the door  170  is turned as shown in  FIG. 2 , in order to make room for the battery casing  110  to rotate relative to the upper machine body  120 . 
     Then, referring to  FIG. 3  and  FIG. 4  together,  FIG. 4  is a schematic view in which the upper machine body of  FIG. 3  is omitted. The user may push the button  140  in a clockwise direction of the drawing so as to press the first elastic member  130 , then the hook  142  of the button may be released from the engaged member  114 , so that the battery casing  110  and the upper machine body  120  are unlatched. In the embodiment, since the second elastic member  150  is disposed between the upper machine body  120  and the battery casing  110 , when the hook  142  of the button  140  is released from the engaged member  114 , the second elastic member  150  may apply a push force to the battery casing  110 . In addition, since the battery casing  110  is pivoted to the upper machine body  120 , the battery casing  110  may rotate a small amount of distance relative to the upper machine body  120  slightly in a counter clockwise direction, as shown in  FIG. 5 . In other words, after the user pushes the button  140 , the battery casing  110  and the first belt structure  180  pivoted to the battery casing  110  may slightly spring to outside, so as to facilitate the user to manually rotate. 
     Referring to  FIG. 6 , the user may rotate the battery casing  110  to the second position P 2  relative to the upper machine body  120 , thereby exposing the battery accommodating space  112 . In the present embodiment, the notch  116  formed on one of the side surfaces of the battery casing  110  may facilitate the user to take out the battery. Certainly, in other embodiments, one of the side surfaces of the battery casing  110  may have an outwardly bending curvature, such that the user may use the finger or finger nail to stretch into and take out the battery. 
     After the new battery  10  is installed, the user may turn the battery casing  110  in clockwise direction. At this moment, as shown in  FIG. 3 , by again pushing the button  140  in clockwise direction to let the battery casing  110  back to the first direction P 1 , the user may release the force applied to the button, then the first elastic member  130  may push the button  140  in counter clockwise direction, so that the hook  142  of the button  140  may be movably fixed to the engaged member  114  of the battery casing  110 . After that, by closing the door  170  to the battery casing  110  and the upper machine body  120 , the wearable device  100  may return to the normal situation as shown in  FIG. 7 . 
     In light of the foregoing, when the battery of the wearable device provided in the disclosure is to be replaced, since the upper machine body is pivoted to the battery casing, only by pushing the button to press the first elastic member, then the hook is released from the engaged member. As such, the battery casing is rotated relative to the upper machine body, so as to expose the battery accommodating space. After battery replacing is completed, by only rotating back the battery casing, the first elastic member may push the hook to the engaged member of the battery casing, and the relative positions between the battery casing and the upper machine body may be fixed, thereby facilitating users to rapidly and conveniently replace the battery of the wearable device. 
     Although the disclosure has been described with reference to the above embodiments, it will be apparent to one of ordinary skill in the art that modifications to the described embodiments may be made without departing from the spirit of the disclosure.
