[0002] After years of development, lead-acid batteries have gradually developed into maintenance-free types; however, some specific products, such as batteries for taxis, trucks, and large machinery / engineering vehicles, require irregular watering maintenance to maintain their service life due to the particularity of their operating conditions. Therefore, they are still designed as open-type batteries. By installing liquid hole plugs, acid level indicators, etc. to seal the battery, water can be added when the liquid is insufficient, and the liquid hole plugs can also play a role in exhausting. In addition, AGM batteries need to exhaust through exhaust plugs to control internal pressure. Therefore, these types of batteries all need to be additionally installed with liquid hole plugs / acid level indicators or exhaust plugs after the battery cover / small cover is sealed. The top surface of the liquid hole plug is circular with multiple protruding corners (usually six), the top surface of the acid level indicator is flat with a straight groove, and the top surface of the AGM battery exhaust plug is a regular hexagon. Instruments and equipment are used to install liquid hole plugs in mass production. The use of instruments and equipment to install liquid hole plugs has high production efficiency, but the equipment is expensive and not easy to carry. When only a small number of test batteries are produced, battery maintenance is performed after laboratory tests, or daily household battery maintenance is performed, installation is only required for a short time. It is not cost-effective to purchase and install equipment with a low probability of use. Therefore, it is necessary to design a tooling equipment with a simple structure, easy to carry, and suitable for the installation of various types of liquid hole plugs / acid level indicators.
