Abstract: The present invention provides a ratchet tool, wherein a circular tooth row is arranged into the round groove of the main body's actuating end. A tool driving seat is assembled rotatably onto the round groove of the main body. A first braking slot, a second braking slot and an arched control slot are triangularly configured onto the internal surface of the tool driving seat. The first and second braking slots are separately fitted with the first and second braking swing blocks. A moveable control gear is placed into the control slot and can shift to the through-hole at both ends of the control slot such that it is mated simultaneously with inner tip edges of the first and second braking swing blocks. An elastic resetter is additionally provided to make the first and second braking swing blocks with inner tip edge swing inwards in a normal state.

Abstract: The present invention provides a tool connecting rod with convertible connectors. The invention includes an outer cylinder, an inner slide, a drive rod, an angular inner rod, an elastic supporting member and first and second locating members. If the drive rod is individually fixed, the tool connecting rod enables its working end to be inserted by the screwdrivers or bolts, or be sleeved optionally for time-saving, ease-of-use and higher flexibility.
