Abstract
A ratchet wrench tool set includes a box, tool bits receivable in the box, two side boards mounted to two sides of the box, and a ratcheting device. The ratcheting device includes a rotary connection plate to which a ratcheting head is mounted. The rotary connection plate is rotatably mounted to the two side boards and rotatable between an operation position and a storage position and includes a constraint step section. The slidable constraint cover has a front end that forms a constraint projection section and is slidably mounted between the two side boards. When the slidable constraint cover is moved frontwards, the constraint projection section engages the constraint step section to retain the ratcheting device in the operation position and when the slidable constraint cover is moved rearward, the constraint projection section disengages from the constraint step section to allow the ratcheting device to rotate to the storage position.
