Abstract: A guiding connection structure is configured to implement mutual guiding connection between a plug-in part installed on a first object and a plug-in part installed on a second object. The guiding connection structure includes a guide pin and a guide sleeve for guiding insertion of the guide pin. The guide pin is installed on the first object, and the guide sleeve is installed on the second object. An inner hole path of the guide sleeve includes a variable-diameter section. A hole diameter of the variable-diameter section gradually increases from one end of the variable-diameter section to the other end of the variable-diameter section. When the guide pin is inserted into the guide sleeve, the guide pin is inserted into the other end of the variable-diameter section from the one end of the variable-diameter section.
