Ratchet wrench having a direction controller that is assembled easily
A ratchet wrench includes a drive head, a ratchet wheel, a direction controller, and a pawl member. The direction controller is formed with a slit facing the expansion slot of the drive head. An insertion plate is mounted in the expansion slot of the drive head, and has a first side provided with a flat cut edge that may be inserted into the slit of the direction controller, and a second side provided with an arcuate edge that is rested on an outer edge of the shaft of the ratchet wheel. Thus, the direction controller may be directly mounted on the drive head, so that the ratchet wrench has a simplified construction and may be assembled and disassembled easily and conveniently.
