The ratchet wrench is a manual screw tightening tool, which has single-end and double-head multi-specification movable handle ratchet wrenches (fixed holes). The main plum blossom sleeves and the slave plum blossom sleeves of different specifications and sizes are connected by a female key and a male key of a hinged key.
Since a plum blossom sleeve has two sizes of plum blossom-shaped through holes, it can be used for the tightening of various specifications of screws, thereby expanding the scope of use and saving raw materials and labor costs.
The movable trigger can easily adjust the angle of use of the wrench. This wrench is used for the tightening operation of screws, and has the characteristics of strong applicability, convenient use and low cost.
Ratchet wrenches are often used by workers when installing and removing pump tubes. Generally, the quality of ratchet wrenches is their durability and longevity, so the manufacturing process is very important.
The ratchet wrench includes: a weight connected to the operating lever, the weight can slide 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. Or, 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 may also have both a front weight carrying part and a rear weight carrying part.
