Electric wrench

Abstract

The invention discloses an electric wrench. The electric wrench comprises a middle cylinder, an outer shell is slidably arranged on the outer surface of the middle cylinder, an extension device enabling the middle cylinder and the outer shell to slide relative to each other to extend the working length of equipment is arranged between the middle cylinder and the outer shell, an internal connectingmotor is arranged in the middle cylinder, a side cylinder is arranged on one side of the internal connecting motor in a power connection mode, a rotating cylinder block is arranged on one side of theside cylinder, a rotating plate driven by the motor is arranged in the rotating cylinder block in a rotating mode, a screwing device driven by the motor to conduct screwing is arranged in the rotating plate, and an open inner cavity is formed in the rotating cylinder block. The device can be lengthened to improve the torque of a worker during the manual screwing so as to achieve the purpose of saving labor, is provided with a structure convenient to install and clamp, enables a tool bit to be convenient to uninstall and install, has the function of multi-angle adjustment, and is suitable formulti-angle work.

Description

Technical field[0001]The invention relates to the technical field of electric tool equipment, in particular to an electric wrench.Background technique[0002]Most of the existing electric wrenches use extension rods in the external space to lengthen the wrenches in order to achieve the extension of the wrench. Due to the torque, the extension rod will increase the rotating torque under the same force. However, in the existing electric wrenches, the extension rod cannot be directly integrated into the equipment, and most electric wrenches cannot achieve multi-angle rotation to make the equipment at an angle suitable for personnel to operate the corresponding nuts or bolts efficiently. Screwing, due to the above shortcomings, the existing electric wrenches cannot meet people’s daily needs, which causes the actual working efficiency and reliability of the equipment to decrease. Due to the above problems, the wrench cannot be used for multiple angles and extensions. Use, so that personnel...

Problems solved by technology

[0002] Most of the existing electric wrenches use the extension rod in the external space to be clamped and lengthened to achieve the lengthening of the wrench. Due to the torque, the extension rod will increase the rotational torque under the same force. , but in the existing electric wrench, the extension rod cannot be directly integrated into the equipment, and most electric wrenches cannot realize multi-angle rotation to make the equipment at an angle suitable for personnel to operate efficiently on the corresponding nuts or bolts. Screwing, due to the existence of the above-mentioned shortcomings, the existing electric wrench cannot meet people's daily needs, which has caused the actual work efficiency and reliability of the equipment to decrease. Use, so that people need to spend a lot of physical strength to use
