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.
