Hi all.
its embarrassed to say I am not sure what I am looking for, a testing connector that be able to clip and release each wire, such like a chip test base :

but clamp individually each wire not the all by one handle.
actually kind of thing like this:

but small one with 2.54mm pin under to insert into breadboard to do test.
all simply how to plug wires onto breadboard to do test:
