FIGS. 13-15 show that when the electronic device 99 is in the second working state, the cover 12 covers the housing 14 completely. The third side surface 1173 faces the guiding surface 1138. When the electronic device 99 switches to the first state from the second working state, the cover 12 is driven to slide on the supporting plate 147. The first rack 124 drives the continuous track 115 to rotate around the base 116. The rotation of the continuous track 115 drives the position apparatus 113 to move, and a intersection of the resisting surface 1137 and the guiding surface 1138 touches the third side surface 1173 and presses the latching member 117. The latching member 117 is driven to rotate along the first rotation direction with the fixing shaft 1175, as shown in FIG. 13. In this process, the second restoration member 118 is compressed. When the main plate 1130 moves continuously, the resisting surface 1137 moves away from the third side plate 1173 and releases the latching member 117, the second restoration member 118 drives the latching member 117 to reversely rotate along the second rotation direction and the resisting surface 1137 resists the sixth side surface 1179, so that the position apparatus 113 is latched. And the position apparatus 113 compresses the first restoration member 1133. Thus the electronic device 99 switches to the first state from the second state.
When the state of the electronic device 99 needs to be switched, the button 119 is manually pushed to slide along the two second grooves 1492. The two latching portions 1192 of the button 119 drive the latching member 117 to rotate along the first rotation direction. The two position shafts 1170 slide in the third slideway 1496 of the controlling portion 149, and then the sixth side surface 1179 is released from the resisting surface 1137. The first restoration member 1133 drives the position apparatus 113 to move, and then the position apparatus 113 drives the continuous track 115 to rotate around the base 116. The slider 123 is driven by the continuous track 115, thus the cover 12 covers the housing 14. The electronic device 99 switches to the second state.
In summary, the electronic device 99 remains stable in the first state by the connecting mechanism 11, and when the button 119 is slid, the position apparatus 113 is released by the latching apparatus 112, and the electronic device 99 switches to the second state automatically. It is convenient for user to switch the state of the electronic device 99.
