Claims (6)

  A gardening tool comprising a rotary drive source and a working unit such as a cutting blade that operates in response to a rotational force from the rotary drive source, wherein the gardening tool is provided with a speed change mechanism unit so that the rotational torque can be increased or decreased. .   The garden tool according to claim 1, wherein a long bar is provided between the rotation drive source and the working unit, and the working unit is detachably provided at one end of the long bar.   The gardening tool according to claim 2, wherein the working unit is a working unit of several types having different operations such as a brush cutter, a hedge trimmer, an edger, and a chainsaw.   A long bar provided with a handle;
  A drive unit provided at one end of the long bar and provided with a rotation drive source;
  A working unit provided at the other end of the long bar and provided with a mounting shaft that operates by receiving a rotational force from the rotational drive source;
  A drive shaft that is inserted into the long bar and transmits the rotational force of the rotational drive source to the working unit;
  A reduction mechanism provided in the drive unit and disposed between the rotation drive source and the drive shaft;
  The output shaft of the rotational drive source and the drive shaft are rotatably supported by the drive unit, and each rotational axis extends substantially parallel to each other.
  The speed reduction mechanism includes a first gear portion provided on an output shaft of the rotation drive source,
  A second gear portion provided at an end of the drive shaft and meshable with the first gear portion;
  A gardening tool characterized by that.   The output shaft of the rotational drive source is positioned below in a plane perpendicular to the axial direction with respect to the end of the drive shaft.
  The garden tool according to claim 4, wherein:   The drive unit is configured to be able to hold a battery capable of supplying power to the rotation drive source.
  The gardening tool according to any one of claims 1 to 5, wherein the gardening tool is provided.
