Problems solved by technology
The existing electric wrench is small and compact, and is held by a person with one hand. The tightening head of the electric wrench is short from the hand-held part, and can only be used under normal conditions. However, people now have higher and higher requirements for fastening reliability, and fastening operations are required. The range of equipment is getting wider and wider. Under operating conditions such as high-altitude liveline work and deep well equipment installation, because the operating point is too far or too deep, the existing electric wrench is inconvenient or impossible to use, which requires some auxiliary equipment. Sending out the electric wrench will increase the operating cost, and even if the electric wrench is sent out through auxiliary equipment, it is not convenient to align the bolts or nuts, let alone work stably and reliably

Description
technical field [0001] The invention relates to the technical field of fastening auxiliary operation equipment, in particular to an electric wrench. Background technique [0002] An electric wrench refers to an electric tool for tightening and loosening bolts and nuts. It is a tool for tightening high-strength bolts. It is used for initial screwing, Final tightening and initial tightening of torsional shear type high-strength bolts, as well as occasions with strict requirements on the torque or axial force of bolt fasteners. The existing electric wrench is small and compact, and is held by a person with one hand. The tightening head of the electric wrench is short from the hand-held part, and can only be used under normal conditions. However, people now have higher and higher requirements for fastening reliability, and fastening operations are required. The range of equipment is getting wider and wider. Under operating conditions such as high-altitude liveline work and deep...
