The abutment component 107 includes an arc-shaped abutment block 121 and an anti-slip pad 122. The aforementioned solution solves the problem that existing tension fittings for lightweight, energy-saving, and environmentally friendly transmission lines cannot effectively fix smaller diameter transmission lines due to the fixed size of the conductor hole inside the conductor cylinder, resulting in poor fixing effect.

[0023] In this specific embodiment, the support arm 102 is disposed on one side of the wedge-shaped cylinder 101; the hanging lug 103 is disposed on one side of the support arm 102; and the reinforcing rib 104 is disposed on one side of the support arm 102.

Then, the transmission line is inserted into the fixing hole in the wedge-shaped cylinder 101. Subsequently, according to the diameter of the transmission line, the operating members 109 on the two sides of the contact frame 108 are operated respectively, which drives the connecting plate 110 to pass through the guide part 111 for guidance and limitation, so that the two contact parts 112 abut and fix according to the diameter of the transmission line.

When the power transmission line is inserted into the fixing hole in the wedge-shaped cylinder 101, the knob 117 is turned so that the locking screw 116 drives the telescopic rod 118 to drive the connecting plate 110 to move.

[0027] In addition, the guide cylinder 119 is fixedly connected to the abutment frame 108 and is located on one side of the abutment frame 108; the guide rod 120 is slidably connected to the guide cylinder 119 and fixedly connected to the connecting plate 110 and is located on one side of the guide cylinder 119. The guide cylinder 119 is used to support the sliding of the guide rod 120, and the guide rod 120 is used to carry and guide the position of the connecting plate 110 when it moves.

[0028] Furthermore, the arc-shaped contact block 121 is fixedly connected to the connecting plate 110 and is located on one side of the connecting plate 110; the anti-slip pad 122 is fixedly connected to the arc-shaped contact block 121 and is located on one side of the arc-shaped contact block 121.

After the power supply line is inserted into the fixing hole in the wedge-shaped cylinder 101, the knob 117 is turned to lock the screw. 116 drives the telescopic rod 118 to move the connecting plate 110. The connecting plate 110, guided by the guide part 111, moves the arc-shaped contact block 121 close to the power transmission line. Then, in conjunction with the anti-slip pad 122, it tightly contacts the power transmission line, so that the two arc-shaped contact blocks 121 can be fixed by contact according to the diameter of the power transmission line. This solves the problem that existing tension fittings for lightweight energy-saving and environmentally friendly power transmission lines cannot effectively fix smaller diameter power transmission lines because the size of the conductor hole inside the conductor tube is fixed, resulting in poor fixing effect.
