When plugging plug, protects the lower end of lantern ring that can offset always with the outer surface of socket, so, can be avoided human body
Finger is in contact with the first conductive sheet or the second conductive sheet, so as to avoid the generation of electric shock accidents, eliminates security risk.
The course of work of the invention is: when needing to change the type of the exposed conductive sheet of plug, it is only necessary to change sleeve
With the plugging direction of slot, i.e., after the sleeve and slot grafting for being located at the first conductive sheet side, the first conductive sheet and conductive seat
It offseting, the second conductive sheet is exposed on the external, at this point, the type of the conductive sheet of entire plug is the conductive sheet of strip sheet, it is such to lead
Electric piece can adapt to domestic two spring hole scoket of flat, and after the sleeve and slot grafting for being located at the second conductive sheet side, second is led
Electric piece offsets with conductive seat, and the first conductive sheet is exposed on the external, at this point, the conductive sheet type of entire plug is cylindrical conduction
Piece, such conductive sheet can adapt to two spring hole scoket of circle in Europe, so that user can replace according to the difference of jack type
The type of conductive sheet, and then can be brought convenience to user;It is led by slide plate, push rod, the first spring, the second conductive plate and first
The setting of battery plate, when the push rod that is located above is detached from shell, i.e., when sleeve and slot loosen, the first spring energy for being located above
Push plate is enough pushed, so that the second conductive plate being located above is detached from the first conductive plate and so can make what is be located above to lead
Electric piece is not charged, thus when underlying conductive sheet is also plugged on socket, and when shell disengaging sleeve, it can be avoided and be located at
The conductive sheet of top is there is also charging, so as to avoid the generation of electric shock accidents;And when underlying push rod is complete
When being held out against entirely with the outer surface of socket, i.e., after underlying conductive sheet is completely inserted into socket, underlying push rod energy
Enough push plate is pushed so, that is, to may make entire socket so that underlying second conductive plate offsets with the first conductive plate
It is powered;By protecting the setting of lantern ring, when plugging plug, protects lantern ring under the action of third spring, protect under lantern ring
End can offset with the outer surface of socket always, and so, the finger and the first conductive sheet or second that can be avoided human body are led
Electric piece is in contact, and so as to avoid the generation of electric shock accidents, eliminates security risk.
