说明书全文	BACKGROUND 1. Technical Field The disclosure generally relates to sliding key modules and electronic devices using the sliding key modules. 2. Description of the Related Art Electronic devices such as mobile phones may include a housing and a sliding key module mounted on the housing for performing functions including activating the mobile phone for operations. However, the structure of the sliding key module can be complicated and difficult to mount to the housing. Therefore, there is room for improvement within the art. BRIEF DESCRIPTION OF THE DRAWINGS Many aspects of the exemplary sliding key module and electronic device can be better understood with reference to the following drawings. The components in the various drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the exemplary sliding key module and electronic device. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the diagrams. FIG. 1 is an exploded view of the electronic device using the sliding key module according to an exemplary embodiment. FIGS. 2 and 3 are assembled views of the electronic device shown in FIG. 1. FIG. 4 is a cross-sectional view of the cover in FIG. 2, taken along line IV-IV. DETAILED DESCRIPTION FIG. 1 shows an exemplary electronic device 100 including a cover 10, a sliding key module 20, a Printed Circuit Board (PCB) 30 and a triggering member 40. The housing 10 includes a side wall 12 and a bottom wall 14 connecting the side wall 12. The side wall 12 defines a through hole 122 and two latching modules 123. The through hole 122 is located between the latching modules 123. Each latching module 123 includes two hooks 124. Each hook 124 includes a latch 1242 and a guide portion 1244 connecting the latch 1242 and the side wall 12. The guide portions 1244 are parallelly staggered in each latching module 123. Each latching module 123 defines a sliding channel 126 among the guide portions 1244, the latches 1242 and the side wall 12. The sliding channels 126 communicate with each other. Each latching module 123 defines a guide channel 128 between the opposite latches 1242 (best shown in FIG. 4). The guide channels 128 communicate with each other. The sliding key module 20 includes a main body 22 and a sliding key 24 slidably mounted on the main body 22. In this exemplary embodiment, the main body 22 is a portion of the cover 10. The side wall 12, the through hole 122 and the hooks 124 are portions of the main body 22. The sliding key 24 includes a first sliding track 242, a board portion 244 fixed to the first sliding track 242, a second sliding track 246 fixed on the first sliding track 242. In addition, a protruding portion 247 projecting from the board portion 244, a fastening portion 248 defined on the second sliding track 246 and two limiting portions 249 fixed on each end of the first sliding track 242. The first sliding track 242 is slidably mounted in the sliding channels 126. The second sliding track 246 is slidably mounted in the guide channels 128. The cross-section of the first track 242 is larger than the second track 246. The protruding portion 247 is slidably mounted in the through hole 122 of the cover 10. The protruding portion 247 extends the through hole 122 for driving the protruding portion 247 to move in the through hole 122. In this exemplary embodiment, the fastening portion 248 is a slot to fasten the sliding key 24 to the triggering member 40. The limiting portions 249 resists against the hooks 124 to prevent the sliding key 24 from separating from the cover 10. The triggering member 40 includes a triggering body 42 and a sliding portion 44 slidably mounted on the triggering body 42. The sliding portion 44 is fastened to the fastening portion 248. An external force can move the sliding portion 44 from one predetermined position to another predetermined position, acting as a switch for the electronic device 100. In FIGS. 2-4, during assembly, an external force is provided to press the first sliding track 242 into the sliding channels 126, until the second sliding track 246 is mounted in the guide channels 128 and the protruding portion 247 is mounted in the through hole 122. The PCB 30 is mounted into the cover 10. The sliding portion 44 on the PCB 30 is fastened to the fastening portion 248. In use, the protruding portion 247 is moved in the through hole 122 under an external force, which can drive the sliding portion 44 to slide relative to the triggering body 42. It is to be understood, however, that even through numerous characteristics and advantages of the exemplary disclosure have been set forth in the foregoing description, together with details of the system and function of the disclosure, 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.
