发明名称 Single-direction operation type ratchet wrench structure
摘要 A single-direction operation type ratchet wrench structure includes an elongated handle, and an identification portion. The handle has one end provided with a socket end, and a ratchet wheel is mounted in the socket end and operated in one direction only. The identification portion is mounted on the handle, and mates with a rotation direction of the ratchet wheel for locking or unlocking a workpiece, so that when a user holds the handle of the single-direction operation type ratchet wrench structure, he may directly identify the correct rotation direction for locking or unlocking the workpiece by the location and the direction of the identification portion on the handle, thereby facilitating the user operating the single-direction operation type ratchet wrench structure.
