Beschreibung
Zusammenfassung:	The material returning clamp comprises a first metal block, a second metal block and a material returning block, a first through hole is formed in the first metal block, a material containing cavity used for containing materials to be plated is communicated with the first through hole, the bottom of the material containing cavity is connected with the second metal block, and the material returning block is connected with the second metal block. A protruding material returning rod is arranged on the end face of one side of the material returning block, a second through hole is formed in the second metal block, and the second through hole is communicated with the bottom of the material containing cavity so that the material returning rod can stretch into the material containing cavity. A to-be-plated material is placed in the material containing cavity from the first through hole, and local vacuum coating is conducted on the to-be-plated material; after coating is completed, the end face of one side of the mate
