Abstract: An adapter includes a metallic connector having an end portion formed with a mounting recess having a bottom formed with an annular flange having a top side formed with a receiving space, a metallic connecting pipe having an end portion inserted into the mounting recess of the metallic connector and stopped by the annular flange of the mounting recess, and a fusible metal paste coated between the mounting recess of the metallic connector and the end portion of the metallic connecting pipe. Thus, the metallic connector and the metallic connecting pipe are combined together rigidly and stably by the fusible metal paste, so that the adapter has a reinforced strength and solidified structure.

Abstract: An adapter includes a metallic connector having a mounting recess, a metallic hose having an end portion inserted into the mounting recess of the metallic connector, and at least one fusible metal ring located between the end portion of the metallic hose and the mounting recess of the metallic connector. Thus, the metallic connector and the metallic hose are combined together rigidly and stably by the fixing portion formed by the fusible metal ring, so that the adapter has a reinforced strength and solidified structure. In addition, the metallic connector and the metallic hose are combined together closely, so that the metallic hose will not detach from the metallic connector during a long-term utilization, thereby enhancing the lifetime of the adapter.
