Lithium electric wrench refers to an electric tool used to tighten and loosen bolts and nuts, and is a tool for tightening high-strength bolts. Used for tightening large hexagonal high-strength bolts and initial tightening of torsional shear type high-strength bolts for steel structure bridges, road guardrail infrastructure, factory buildings, chemical engineering, and power generation equipment installation, as well as occasions with strict requirements for the torque or axial force of bolt fasteners.

Lithium electric wrench refers to an electric tool used to tighten and loosen bolts and nuts, and is a tool for tightening high-strength bolts. Mainly used as a tool for tightening bolts during the construction of building shelves, as well as for hardware assembly, assembly line installation, and some car repairs. 1. Battery usage time: When installing the shelf, one battery can be used for a whole day. Two batteries can be used for a whole day when dismantling the rack. This is the usage time of lithium-ion wrenches that workers are currently using batteries from other brands, hoping for longer battery life; 2. The torque should be large, the impact speed should be fast, and the efficiency should be high; 3. The workers expressed the hope that the gun body can be lighter than most brands of lithium electric wrenches on the market, which is easy to use and reduces the fatigue of opponents who use it for a long time.
