The utility model belongs to the technical field of the electrical equipment technique of maintaining and specifically relates to a sharp shoulder pole card for changing sharp insulator chain that singly goes here and there is related to. The base seat is put on the circuit angle steel, and the fixture main part is passed through base screw and is connected with the base, and fixture main part both ends are connected with the hydraulic pressure lead screw, and the hydraulic pressure lead screw is connected with the lifting sub through insulating pull -rod, and the lifting sub is passed through connecting bolt and is connected with overhead power line fitting company board. The utility model discloses there is following beneficial effect: the utility model discloses a shortcoming that prior art exists is overcome to fixture, does not promote the wire, directly carries the yoke plate. This shoulder pole card is changed the insulator chain during operation and is tightened up the lead screw, and starting line way gold utensil yoke plate is carried in the lifting sub, and lax insulator chain can change. Because it does not promote the wire directly to promote the yoke plate, fixture can not hindered to the wire, and the wire can not take place the bending deformation yet, the utility model discloses fixture simple structure, light in weight, easy and simple to handle, give electrified change the straight line singly go here and there the insulator chain operation brought convenient.
