ABSTRACT:
An apparatus for the cutting of tree limbs includes an extensible drive shaft that is detachably-attachable at one end to a portable electric drill and is secured to a housing at an opposite end thereof. The housing converts the rotary motion that is supplied by the drill into reciprocating motion of a saw blade and it disposes the saw blade at an angle with respect to the drive shaft that is slightly less than 90 degrees. An extensible two-part cylindrical outer sleeve covers the drive shaft and is detachably-attached at one end thereof to the drill and at an opposite end to the housing. A hook is provided in the housing and is used to grab and urge severed limbs where desired. An optional clamping mechanism is attached to the housing and is used initially to urge the blade and the limb toward each other during cutting and then to retain the limb proximate the housing after it has been cut for controlled placement and safe release of the limb.
