[0015] The present invention provides a fixing device for tightening an overhead line, which has the following beneficial effects: (1) The overhead line tightening fixture passes the cable through the gap between the first drum and the second drum and fixes it on the circumferential surface of the winding rod. Once the cable is subjected to external tension, the cable moves to drive the second drum to rotate. At the same time, the rotation of the second drum drives the tooth block to rotate clockwise. The tooth block is limited by the inner wall of the slot one and cannot rotate, thereby limiting the movement of the cable. This can effectively prevent the cable from slipping, thereby reducing damage to the cable caused by friction and wear, preventing the cable from loosening and shaking, and maintaining the stability of the cable. The movement of the inclined rod drives the fixing plate to move downward. At the same time, the movement of the fixing plate drives the fixing column to move downward. The downward movement of the fixing column drives the pressure plate to move until the pressure plate presses the cable tightly, further preventing the cable from loosening and shaking, maintaining the stability of the cable, reducing mechanical damage or cable fatigue caused by vibration, and making the contact between the cable and the fixture closer through uniform contact force.

[0016] (2) The fixing device for tightening the overhead line drives the knocking rod to rotate around the rotating frame through the rotation of the linkage rod 2. The knocking rod rotates to knock off the snow, water drops and bird excrement attached to the surface of the cable, so as to timely remove the snow and ice on the surface of the cable, reduce the cable load, and prevent the line from breaking or equipment damage caused by excessive snow. The movement of the convex plate will stretch the spring. When the fixing tube stops moving, the spring returns to normal and drives the convex plate to move in the direction close to the convex strip. The convex plate moves to contact and hit the convex strip to generate vibration, which breaks the ice attached to the surface of the knocking rod by knocking. By knocking away the ice, the equipment can be quickly restored to work and the downtime can be reduced.

[0017] (3) The overhead line tensioning fixture drives the sliding block to move by moving the connecting block, and the sliding block drives the shovel to move, so as to clean up the snow and debris accumulated on the top of the fixing frame. Excessive snow accumulation will increase the bearing pressure of the fixing frame and thus affect the stability of the overhead line. Bird droppings often pollute the environment around the power line. The movement of the sliding rod drives the movement of the reflective plate, and then realizes the up and down reciprocating motion of the reflective plate, thereby driving away the birds, effectively preventing birds from perching in these places and reducing the risk of electric shock. The continuous reflected light of the reflective plate will cause visual interference and stimulate the birds to fly away. BRIEF DESCRIPTION OF THE DRAWINGS
