It is one of Y series Electric Torque Wrenches made in company and it is also called “Electric Constant torque wrench”. This wrench has a Y-shape reaction arm, or you can call it “Y-shape reaction rod”. This kind of wrench uses the reaction force of the reaction rod to tighten the bolt. In actual construction, a support point must be found at the construction site to prevent this Y-shape rod from rotating. Otherwise , the inner socket and the outer socket will rotate at the same time , and the wrench will perform invalid work.
