What are the advantages of ratchet wrenches?
A ratchet wrench can be used to rotate a bolt or nut placed in a narrow or hard-to-reach position. The ratchet wrench is rotatably connected to the end of the operating rod. The ratchet wrench has a weight connected to the
operating lever. The weight slides along the length direction of the operating lever, and the operating lever at the front of the weight has a front-weight-bearing portion that blocks the collision of the weight. Alternatively, the operating lever at the rear of the weight has a rear-weight-bearing portion that blocks the collision of the weight. Moreover, the operating lever can have both a front-weight-bearing portion and a rear-weight-bearing portion. Thus, users can save time and effort and improve work efficiency.
