摘要：
本实用新型公开一种用于更换双联串绝缘子的紧线器，包括两个套筒(1)、手柄组件(2)、和连接丝杆I(3)和连接丝杆II(4)，手柄组件包括棘轮机构和手柄，连接丝杆I和连接丝杆II通过螺纹连接在套筒内；还包括连接部件I(5)和连接部件II(6)，连接部件I通过螺纹连接在连接丝杆I的左端，连接部件II具有左挂板(61)和右挂板(62)，连接丝杆II的右端面设有连接板(41)，右挂板与双联串绝缘子的双联板通过螺栓相连，左挂板和连接板上均具有长圆形螺栓孔并通过螺栓相连。本实用新型通过可拆卸替换的挂板或挂钩连接双联板，并可调节紧线器与双联板的相对位置和角度，提高了工作的安全性，降低了作业人员的工作强度。
摘要（英）：

The utility model discloses a wire-tightening device used for replacing a double-string insulator. The wire-tightening device comprises two sleeves (1), a handle assembly (2), a connecting lead screw I (3) and a connecting lead screw II (4). The handle assembly comprises a ratchet wheel mechanism and a handle. The connecting lead screw I and the connecting lead screw II are connected in the sleeves via threads. The wire-tightening device also comprises a connecting part I (5) and a connecting part II (6). The connecting part I is connected with the left end of the connecting lead screw I via the threads. The connecting part II is provided with a left hanging plate (61) and a right hanging plate (62). The right end surface of the connecting lead screw II is provided with a connecting plate (41). The right hanging plate and the double-plate of the double-string insulator are connected via bolts. The left hanging plate and the connecting plate are provided with long circular bolt holes and connected via the bolts. The double-plate is connected via the detachable replacing hanging plates or hanging hooks, and the relative position and angle of the wire-tightening device and the double-plate can be adjusted so that work safety is enhanced and work intensity of operation personnel is reduced.
