In embodiment, the elastomeric element 5 is spring.
In use, when stressed member 3 is located at first position, first end 31 is in the first height (in insulating base 1
Top surface be plane and it is horizontally disposed in the case of, height that first end 31 protrudes from the first opening 11 for example can be 2mm~
3mm), naturally it is also possible to further mobile second end 32 make stressed member 3 be directed away from the second place direction rotate (for
Two stressed members 3 in Fig. 1, by second end 32 towards pulling outside accommodating chamber 12, make second end 32 towards shifting outside accommodating chamber 12
It is dynamic, make second end 32 away from accommodating chamber 12；If two reversing of position of stressed member 3 in Fig. 1, need second end
32 press towards in accommodating chamber 12, second end 32 is made second end 32 close to accommodating chamber 12 towards moving in accommodating chamber 12), then
Height residing for first end 31 further reduces, and does not protrude from the first opening 11 even, now can be by the conductor 2 of attaching plug
The second end 22 insert in power outlet, for prominent first end 31 against power outlet, prominent first end 31 can be with
Prevent finger from touching the second end 22 of the conductor 2 of attaching plug, prevent from getting an electric shock.
When needing to extract attaching plug, mobile second end 32 makes stressed member 3 be rotated towards the second place (for Fig. 1
In two stressed members 3, second end 32 is pressed towards in accommodating chamber 12, makes second end 32 towards moving in accommodating chamber 12,
Make second end 32 close to accommodating chamber 12；If two reversing of position of stressed member 3 in Fig. 1, need second end 32
Pulled outside towards accommodating chamber 12, second end 32 is made second end 32 away from accommodating chamber 12 towards movement outside accommodating chamber 12), until
Stressed member 3 reaches the second place, and first end 31 is in second height highly higher than first (in the top surface of insulating base 1
For plane and it is horizontally disposed in the case of, first end 31 protrudes from the height increase of the first opening 11, for example, can be 3mm~
6mm), so as to which the insulating base 1 of attaching plug is lifted off power outlet by first end 31, and then by the conductor 2 of attaching plug
Power outlet is extracted in the part of the second end 22, so that attaching plug loosens, then attaching plug is extracted, similarly, mistake herein
Cheng Zhong, prominent first end 31 can prevent the second end 22 for the conductor 2 that finger touches attaching plug, prevent from getting an electric shock.
Using the present invention, attaching plug easily can be extracted under security situation, be mainly reflected in：
(1) more convenience.When extracting attaching plug, the power in direction will be extracted, change into and laterally pinch power or laterally pull
Power, attaching plug is loosened, then attaching plug is extracted.
(2) security is increased.When extracting attaching plug, prominent first end can prevent finger from touching power supply and inserting
The second end of the conductor of head, prevents from getting an electric shock.
To sum up, than relatively labor-saving when safe portable attaching plug of the invention enables to the attaching plug to extract, user
Just, increase the convenience of attaching plug, Danger Electric shock risk when attaching plug is extracted can be prevented, increase the safety of attaching plug
Property, ingenious in design, simple for structure, manufacture is easy, and cost is low, suitable for large-scale promotion application.
As can be seen here, the purpose of the present invention is achieved completely and effectively.The function and structural principle of the present invention
Shown and illustrated in embodiment, under without departing substantially from the principle, embodiment can make any modification.So this hair
The bright all variant embodiments included based on claim spirit and right.
