projections

62, 63 of the first coupling member 61, and the lower two receiving grooves 67 engage with the two

projections

71, 72 of the third coupling member 70.

Referring to fig. 1 to 5, when the first protective housing 1 and the second protective housing 40 are stacked together for carrying, a user only needs to stack the first protective housing 1 on the second protective housing 40 and align the grooves 55, 59 on the

front walls

2, 49 and the grooves (not shown) on the

rear walls

3, 46 of the two

protective housings

1, 40, respectively. Thereafter, the second coupling member 65 is rotated in a direction away from the

front walls

2, 49 of the first protective housing 1 and the second protective housing 40, so that the four receiving

grooves

66, 67 of the second coupling member 65 are disengaged from the two

protrusions

71, 72 of the third coupling member 70 and the two

protrusions

76, 77 of the positioning member 75. Thereafter, the user may slide the second connecting member 65 upward along the guide groove 58 until the two upper receiving grooves 66 of the second connecting member 65 are aligned with the two

protrusions

62, 63 of the first connecting member 61, and the two lower receiving grooves 67 of the second connecting member 65 are aligned with the two

protrusions

71, 72 of the third connecting member 70. Then, the user can rotate the second coupling member 65 in a direction toward the

front walls

2, 49 of the first and

second shield shells

1, 40 such that the two receiving grooves 66 of the upper portion of the second coupling member 65 are engaged with the two

protrusions

62, 63 of the first coupling member 61, and at the same time, the two receiving grooves 67 of the lower portion of the second coupling member 65 are engaged with the two

protrusions

71, 72 of the third coupling member 70. At this time, the connecting assembly 60 can stack the first protective housing 1 and the second protective housing 40 into a portable unit, i.e., the audio device 10 and the heating device 41 can be stacked into a portable unit. The connection mode is very firm and is convenient to carry.

When the audio device 10 and the heating device 41 are to be used separately and the first protective housing 1 is to be separated from the second protective housing 40, the user only needs to rotate the second coupling member 65 in a direction away from the

front walls

slots

66, 67 of the second coupling member 65 are disengaged from the two

protrusions

62, 63 of the first coupling member 61 and the two

protrusions

71, 72 of the third coupling member 70, and then the first protective housing 1 and the second protective housing 40 can be detached for use separately.

In order for the second connecting member 65 not to interfere with the normal use of the second protective housing 40, the user needs to slide the second connecting member 65 downward along the guide groove 58 until the two receiving grooves 66 of the upper portion of the second connecting member 65 are aligned with the two

protrusions

71, 72 of the third connecting member 70 and the two receiving grooves 67 of the lower portion of the second connecting member 65 are aligned with the two

protrusions

76, 77 of the positioning member 75. The user can then turn the second connecting member 65 in a direction towards the front wall 49 of the second protective housing 40 so that the upper two receiving slots 66 of the second connecting member 65 engage with the two

projections

71, 72 of the third connecting member 70, while the lower two receiving slots 67 of the second connecting member 65 engage with the two

projections

76, 77 of the positioning member 75, at which time the second connecting member 65 returns to the non-use position. When the second protective housing 40 and the heating device 41 are carried and used separately, the second connecting element 65 is firmly located at the non-use position, which does not cause unnecessary obstacles to the use of the heating device 41, for example, if the four

grooves

66, 67 of the second connecting element 65 are located at any one of the

non-receiving protrusions

71, 72, 76, 77, the user may be scratched or caught by the reinforcing bars, sundries, etc. on the construction site, which may cause unnecessary troubles to the user.

It will be understood by those skilled in the art that the connecting assembly 60 may also be disposed on the

side walls

respective shield shells

1, 40, 80 is easy, and the connecting member 60 can easily connect the

respective shield shells

1, 40, 80 into one body for convenient carrying.

As will be appreciated by those skilled in the art, since the

protective housings

1, 40, 80 can accommodate different devices, a plurality of audio devices 10 can be conveniently stacked as a portable unit, a plurality of heating devices 41 can be conveniently stacked as a portable unit, and a plurality of cooling devices 81 can be conveniently stacked as a portable unit. The combined electric appliance can also comprise an oven, an electric cooker, a television and other electric appliances.

It will be appreciated by those skilled in the art that the plug may be a three-pin plug and the receptacle may be a three-pin receptacle.

The connecting assembly 60 detachably and stackable integrally assembles the first protective casing 1 for accommodating the audio device 10, the second protective casing 40 for accommodating the heating device 41 and the third protective casing 80 for accommodating the refrigerating device 81, and has simple structure and portability, and because the

protective casings

1, 40 and 80 are uniformly formed and have stronger vibration resistance, the reliable protection is provided for the accommodated audio device 10, the heating device 41 and the refrigerating device 81, the possibility that the audio device 10, the heating device 41 and the refrigerating device 81 are damaged by falling weights on the construction site is greatly reduced, and even if the audio device 40, the heating device 41 and the refrigerating device 81 are accidentally fallen to the ground, the possibility that the audio device 40, the heating device 41 and the refrigerating device 81 are damaged is also greatly reduced.

Since the

protective housings

1, 40, 80 can be stacked and assembled into a whole, the respective electric appliances housed therein, such as the audio device 10, the heating device 41, and the cooling device 81, are respectively disposed in separate housings, and are relatively safe when used at the same time.
