发明名称 Quick switching hand tool
摘要 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.
