摘要： A pruner attachment apparatus includes a body releasably attachable to a shoe of a power tool of the type having a reciprocating saw blade. The body includes a front face for engaging a workpiece. The pruner attachment apparatus further includes a hook member for engaging the workpiece. The hook member is laterally spaced from the saw blade of the tool and is mounted to the body for movement along a path between a first position and a second position. The path includes an upper curvilinear portion configured such that movement of the hook member from the first position to the second position positions the hook member completely behind an imaginary line in a common plane with the front face. A biasing mechanism biases the hook member to the second position.

摘要： A pruner attachment apparatus for a power tool having a body, a shoe extending from the body, and a saw blade interconnected to the body for reciprocating motion. The pruner attachment apparatus includes a mounting member, a hook member and a biasing mechanism. The mounting member is releasably attachable to the shoe. The hook member is carried by the mounting member for movement between a first position and a second position. The biasing mechanism biases the hook member to the second position.
摘要翻译：一种用于具有主体的动力工具的修剪器附接装置，从主体延伸的鞋，以及与主体互连以用于往复运动的锯片。修剪器附接装置包括安装构件，钩构件和偏置机构。安装构件可释放地附接到鞋。钩构件由安装构件承载，用于在第一位置和第二位置之间移动。偏置机构将钩构件偏置到第二位置。
