Abstract
A quick switching hand tool comprises a driving head having a ratchet teeth portion; a control device having a control rod; the control rod being installed with a driving block which is interacted with a buckle unit; and the buckle unit is engageable to the ratchet teeth portion. When the control rod is pressed, the control rod will drive the driving block to rotate so that the buckle unit shifts with the driving block so as to switch the restoring direction of the driving head. Furthermore, in another design, the buckle unit has two buckle teeth blocks. Each buckle teeth block is pivotally installed to the driving head and the buckle unit is engageable to the ratchet teeth portion; an outer end of the driving block has an resisting rib for controlling positions of the buckle teeth block.

A quick switching hand tool comprising:
- a driving head having a ratchet teeth portion;
- and
- a control device having a control rod;
- the control rod being installed with a driving block which is interacted with a buckle unit;
- the buckle unit having two buckle teeth blocks;
- each buckle teeth block being pivotally installed to the driving head and the buckle unit is engageable to the ratchet teeth portion;
- an outer end of the driving block having an resisting rib for controlling positions of the buckle teeth blocks;
- the control rod installed with at least one interaction unit and an inner surface of the driving block formed with at least one inclined cambered trench;
- the driving block installed to the control rod;
- and the interaction unit embedded into the inclined cambered trench;
- wherein the interaction unit moves along the inclined cambered trench to drive the driving block to rotate when the control rod is pressed so that the buckle unit shifts with the driving block to switch the restoring direction of the driving head.
