    • A power saw pruning device (A) is disclosed which utilizes a conventional saber saw (14) for pruning trees. The device includes an elongated pole handle (10) and a base adaptor (12) carried on one end of the elongated pole handle. The base (12) includes a rack (16, 18) in which a shoe (20) of the saber saw slides in opposing directions in one dimension. An elongated slot (26) is formed in the base (12) for receiving a blade (28) of the saber saw therethrough. Angle arm means (B) includes an angle edge (44) which tapers from an open mouth (46) to the base (12) for gripping a tree limb (40) therein. The plane of the angle arm (42) is offset relative to the plane of the blade (28). By hanging the device on a tree limb to be cut, an operator may move to a remote position and operate the power saw by a switch (32). After the tree limb is cut through, the device remains suspended on a stump (40a) of the tree limb which has been cut. After the limb has fallen to the ground the operator may remove the device from the stump (40a).
    • 公开了一种动力锯切割机(A),其使用传统的刀锯(14)来修剪树木。 该装置包括细长的极手柄(10)和承载在细长杆手柄的一端上的底座适配器(12)。 基座(12)包括一个齿条(16,18),其中一个维度上的剑刀的鞋(20)沿相反的方向滑动。 在基座(12)中形成有细长的槽(26),用于容纳通过其中的剑刀的刀片(28)。 角臂装置(B)包括从开口(46)向基座(12)逐渐变细的角度边缘(44),用于夹住树枝(40)。 角臂(42)的平面相对于叶片(28)的平面偏移。 通过将设备悬挂在要切割的树枝上,操作者可以移动到远程位置并且通过开关(32)操作动力锯。 在树枝切割后,设备保持悬挂在已被切割的树枝的树桩(40a)上。 在肢体已经落到地面之后,操作者可以从残端(40a)中移除装置。
