Multifunctional torque wrench

Abstract

The invention discloses a multifunctional torque wrench. The multifunctional torque wrench comprises a machine shell, a handle and a nut sleeve, wherein a motor is arranged inside the machine shell. The motor is connected with the nut sleeve through a transmission shaft. The motor can drive the transmission shaft to rotate forwards and reversely. A torque sensor is arranged between the transmission shaft and the nut sleeve. The nut sleeve is detachable. The torque sensor can also be connected with a drill bit through a detachable connecting piece. Switch keys of different gears are arranged on the handle. According to the structure, the motor can rotate forwards and reversely; when the motor rotates forwards (the motor can also rotate reversely), the motor has impact, the torque sensor is connected with a connector and the drill bit, and the multifunctional torque wrench can be used as a drilling machine to drill holes; when the motor rotates reversely (the motor can also rotate forwards), the motor does not have impact, the torque sensor is directly connected with the nut sleeve, and the multifunctional torque wrench can be used as a torque wrench to tighten a nut. The multifunctional torque wrench has two functions and is convenient to carry and use, particularly suitable for high-altitude carrying and capable of reducing the operation load.

Description

technical field [0001] The invention relates to a torque wrench, in particular to a multifunctional torque wrench. Background technique [0002] At present, electric torque wrenches are used more and more frequently. However, existing electric torque wrenches cannot be drilled because the motor does not have impact, and can only be used as tightening nuts. If it is necessary to drill holes, you need to carry a drilling machine in addition. The drilling machine is heavy and inconvenient to carry. If it is a high-altitude operation, it will increase the operator's load and increase the safety risk. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multifunctional torque wrench capable of drilling holes and convenient to carry in view of the above-mentioned deficiencies in the prior art. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invent...

Problems solved by technology

[0002] At present, electric torque wrenches are used more and more frequently. However, the existing electric torque wrenches cannot be drilled because the motor does not have impact, and can only be used as tightening nuts.

If you need to drill holes, you need to carry another drilling machine. The drilling machine is heavy and inconvenient to carry. If it is working at high altitude, it will increase the operator's load and increase the safety risk.
