Tightener for electric power installation

The utility model relates to the technical field of power installation equipment. The utility model relates to a wire grip, in particular to a wire grip for power installation. The device comprises athread hooking mechanism and a rocker mechanism, the tightener for electric power installation also comprises a bidirectional coiling mechanism. The two thread hooking mechanisms are connected to thetwo ends of the two-way thread winding mechanism in a mirror image sliding mode. According to the bidirectional wire winding device, wire tightening work can be conducted at the speed twice that of the bidirectional wire winding mechanism, automatic wire loosening can be achieved after wire tightening is completed, an operator can apply force more conveniently, the working efficiency is improved,and potential safety hazards of the operator are reduced. 本实用新型涉及电力安装设备技术领域，更具体的说是一种电力安装用紧线器，包括勾线机构和摇杆机构，该电力安装用紧线器还包括双向卷线机构，所述两个勾线机构镜像滑动连接在双向卷线机构的两端，所述摇杆机构转动连接在双向卷线机构的前端，该装置可以以两倍的速度进行紧线工作，紧线完成后可自动松线，并且该装置可以让操作人员更加方便的用力，提高工作效率，并
