Abstract

An extendable cutting tool (100) includes a longitudinal member (102) having a first end (104) and a second end (106). The extendable cutting tool (100) includes a pair of cutting blades (108) coupled to the longitudinal member (102) toward the first end (104). The extendable cutting tool (100) includes a sleeve member (110) concentrically coupled to the longitudinal member (102) toward the second end (106). Sliding movement of the sleeve member (110) toward the second end (106) of the longitudinal member (102) causes the pair of cutting blades (108) to move from the first position toward the second position. The extendable cutting tool (100) is characterized in that rotational movement and reversible deformation of the sleeve member (110) in a first rotational direction locks movement of the sleeve member (110) and a pair of cutting blades (108) ) is motion-locked between the first position and the second position.

Description

technical field [0001] The present disclosure relates to extendable cutting tools. More specifically, the present disclosure relates to extendable cutting implements, such as pole pruners. Background technique [0002] Conventional extendable cutting implements, such as pole pruners, are used for pruning trees, especially trees located at heights substantially out of reach of ordinary users. The extendable cutting tool has a longitudinal member including a pair of cutting blades at one end. The longitudinal members can be extended to different heights as desired and then used to perform trimming operations using a pair of cutting blades. Further, the extendable cutting tool includes a sleeve member to control trimming performed by the pair of cutting blades, including locking the pair of cutting blades. There have been various developments concerning pruning or cutting operations with extendable cutting tools. [0003] However, during operation of the extendable cutting ...
