Description

Sustainable lubrication lithium electric wrench Technical Field The invention relates to the technical field of electric wrenches, in particular to a lithium electric wrench capable of being lubricated continuously. Background The electric spanner is an electric tool which uses electric power as power and is specially used for screwing or disassembling bolts/nuts, and has the core function of efficiently completing high-torque fastening operation. At present, a plurality of lithium battery wrenches exist on the market, but in the long-time use process of the lithium battery wrenches, quick or continuous lubrication cannot be realized, the service life of the lithium battery wrenches can be greatly shortened due to the use under a non-lubrication state, and the lithium battery wrenches are required to be maintained by specialized staff, so that the use cost and the operation trouble are increased. Therefore, a lithium battery wrench capable of continuously lubricating is provided. Disclosure of Invention This section is intended to outline some aspects of embodiments of the application and to briefly introduce some preferred embodiments.
