The utility model provides a multinational converter is through setting up a plurality of from the jam plate, when using one of them bolt subassembly, can promote corresponding from the jam plate removal in order to let out bolt subassembly when this bolt subassembly stretches out, and this bolt subassembly drives all the other from the jam plate removal simultaneously, make all the other from the jam plate keep out all the other bolt subassemblies respectively, stretch out with the relative casing of preventing all the other bolt subassemblies, thereby other bolt subassemblies can't stretch out outside the casing, effectively prevent that other bolt subassemblies from stretching out outside the casing and leading to the user to electrocute, thereby guarantee that this multinational converter security performance is good. Simultaneously, through setting up the jam plate along bolt assembly's flexible direction separately, the self-locking plate can be followed the left and right sides direction removal of casing and in order to open or block corresponding bolt assembly, and the self-locking plate removes the stroke little, and occupation space is little, simple structure and compactness.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
