<P>PROBLEM TO BE SOLVED: To solve the problem with a conventional technique, wherein a fixing sleeve to mount a bit is required, and a function of a one-way ratchet unit is not maintained, if a direction changing operation is added to designing of a combination mode in a conventional hand-held tool, which makes a structure ineffective. <P>SOLUTION: The present invention relates to a ratchet type hand-held tool structure, wherein a ratchet unit is fixed to a bit end of a hand-held tool, the outer diameter size of the ratchet unit corresponds to a shaft diameter of extension shaft of the hand-held tool, and the central shaft line of the ratchet unit is positioned on the extension line of central shaft line of the extension shaft, and the extension shaft includes at least a bend. The ratchet unit is provided to be directly fixed to the bit through the above designing, and the bending change of the extension shaft is also combined with the one-way control of the ratchet unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
