[0027] In use, when the upper shell 3 and the lower shell 2 are connected together, the rubber block 12 on the top of the lower shell 2 is clamped into the clamping groove 13 at the bottom of the upper shell 3, thereby increasing the tightness of the connection between the upper shell 3 and the lower shell 2.
