Anti-retraction acid extractor

The utility model discloses an anti-retraction acid extractor, and relates to the technical field of storage battery acid extraction devices. The acid extractor comprises an acid extraction header pipe communicated with a negative pressure device, wherein the acid extraction header pipe is axially communicated with a plurality of acid extraction branch pipes at intervals and plugs propped against the tops of the acid extraction branch pipes; a plurality of notches are respectively formed in two ends of the acid extraction branch pipe; the end face, close to the acid extraction branch pipe, of the plug is provided with an annular inserting groove used for inserting the acid extraction branch pipe. According to the acid extraction device, the plugs which are mutually abutted and matched with the acid extraction branch pipes are arranged on the acid extraction header pipe, so that the plugs are used for abutting against the acid extraction branch pipes to prevent the acid extraction branch pipes from loosening a
