second embodiment

[0017]FIG. 3 shows the protection device of the present invention, wherein the slot 121A is defined through a wall of the base of the box 10A and the receptacle 22A is located at an end of the timer 20A, so that the cable 21A connected with the plug extends through the slot 121A.

third embodiment

[0018]FIGS. 4 to 6 show the protection device of the present invention, wherein the cover 12B of the box 10B is fixed to the base 11B by at least one bolt 3B. In this embodiment, the base 11B includes a fixing frame 113B which includes two threaded holes 114B and the bolts 3B extend through the cover 10B and are fixed to the two threaded holes 114B to connect the cover 12B to the base 11B. The cover 12b includes a window 124B through which the timer 20B extends and located beyond the top of the cover 12B. A protection cap 4B is pivotably connected to the cover 10B so as to cover the timer 20B and the bolts 3B as shown in FIG. 6.

[0019]The lock 122B is located on the top of the cover 10B and locks a hole 41B in the protection cap 4B such that the timer 20B and the bolts 3B can only be accessed by authorized persons by using a key to unlock the lock 122B.
