The clasping portion is adapted for the clasping hole 301 properly, such as the matching status of the same shape, size and position between the clasping portion and clasping hole 301.
Specifically, the clasping portion 350 is disposed on the assembly surface of the micro-buckling connection portion 300. The clasping hole 301 disposed in the rear shell body 130 correspondingly adapts to the clasping portion 350 to be passed therethrough. A plurality of clasping rings 400 are disposed on the internal side of the rear shell body 130 in form of two opposite concave shapes, as shown by the dashed line in FIG. 2. The clasping rings 400 are used to clasp the opposite recesses of the clasping portion 350 for holding the micro-buckling connection portion 300 when the clasping portion 350 is inserted to the rear shell body 130 correspondingly. In other words, the clasping portion 350 is embedded to the clasping ring 400 in the clasping hole 301 so that the leather cover 200 is connected to the rear shell body 130 of the smart phone 100 by way of the micro-buckling connection portion 300. Thus, after the leather cover 200 is removed from the smart phone 100, only two square clasping holes 301 remain in the rear shell body 130. Therefore, the leafing leather cover is easily disassembled and the case of smart phone 100 is conveniently cleaned to maintain the leafing leather cover sanitary.
Preferably, the clasping rings 400 is fastened to the clasping hole 301 of the rear shell body 130 by way of the strip ribs or posts (not shown) in the internal side of the rear shell body 130.
