Abstract
A wrench driven rotation hand tool with side handle; as required, an independent axial knob and a lateral side handle are selected to be incorporated together with a transmission gear set to a column; the output end of the transmission gear set is provided to drive a main shaft, thus to further drive a cutter or tool; and the input end of the transmission gear is manually driven by a reciprocal handle.
Claims25
A wrench drive rotation hand tool with a side handle, A wrench driven rotation hand tool with side handle of the present invention has at the middle of its column provided a transmission gear set. One end of the column is provided with a main shaft driven by the transmission gear set, and the main shaft in turn drives a cutter or a tool locked to the hand tool;
- a transmission gearbox is provided with a manually driven, reciprocal wrench handle;
- as required, a lateral side handle extending in radius may be provided to the middle of the column and an axial knob, to the end of the column not provided with the main shaft;
- either of the lateral side handle or the axial knob, if not both, must be provided;
- the relative angle between the lateral side handle and the reciprocal wrenching handle may be determined as required or made adjustable;
- with the specific structure as described above, the manually reciprocal wrenching is applied to drive the transmission gear set through a one-way transmission, and further to drive the main shaft for producing rotation drive;
- or the main shaft is driven by a transmission gear set of constant speed ratio, acceleration, reduction, variable speed, or variable direction to exercise rotation drive in conjunction with the tool adapted to a chuck incorporated to the main shaft, thus to achieve the purpose of manually driven drilling, or fastening or loosening a screw, nut or wooden screw:
