Abstract
A pruning hook includes an extension shank (10), a blade unit (40) including a fixed blade (42) mounted on the extension shank and a movable blade (41) pivotally connected with the fixed blade, a driving cord (100) to drive the movable blade, a sliding member (20) movably mounted in the extension shank to drive the driving cord, a control cord (200) mounted in the extension shank to drive the sliding member, and a control member (30) movably mounted on the extension shank to drive the control cord. Thus, the extension shank protects the control cord and the driving cord to prevent the control cord and the driving cord from being hooked or scratched by foreign objects, such as branches and the like, during operation of the blade unit.
