When the socket 20 and the plug 10 need to be separated, or the first connecting piece 100 and the second connecting piece 200 need to be detached, the pulling operation piece 124 is far away from the fixed seat 121, when the movable piece 122 and the fixed seat 121 form an angle of about 45 degrees, the buckle 123 can be separated from the hook, the first connecting piece 100 and the second connecting piece 200 are separated, and then the socket 20 and the plug 10 can also be separated.
It is to be understood that the disclosure is not limited in its application to the details of construction and the arrangements of the components set forth in the specification. The present disclosure is capable of other embodiments and of being practiced and carried out in various ways. The foregoing variations and modifications are within the scope of the present disclosure. It should be understood that the disclosure disclosed and defined in this specification extends to all alternative combinations of two or more of the individual features mentioned or evident from the text and/or drawings. All of these different combinations constitute various alternative aspects of the present disclosure. The embodiments of this specification illustrate the best mode known for carrying out the disclosure and will enable those skilled in the art to utilize the disclosure.
