Embodiment Construction

[0020] from figure 2 It can be seen that when the well cover is opened, the switch 2 is inserted into the hole of the rotating disk 3 through the locking hole of the well cover 1, and the switch 2 is rotated, (from Figure 4 See as counterclockwise), drive rotating disc 3 to rotate on 2 pieces of guide rotation rod 4, and 2 pieces of hinged shaft 5 drive 2 pieces of locking lever 6 to retract on it. When the well cover is closed, the switch rotates in the opposite direction, (from Figure 4 look clockwise).
