[0019] A limiting slot block 11 is welded to the left side of the tension clamp body 1, and the limiting slot block 11 is pushed and connected to a connecting slider 42 through a second spring 43. An adjusting side plate 4 is welded to the lower end face of the connecting slider 42, and the inner side of the adjusting side plate 4 is connected to a limiting hook 3 through a fixing block 33. A hook ring 21 is hooked on the surface of the limiting hook 3, and a limiting pull plate 2 is welded to the right end of the hook ring 21. A movable ring block 22 is connected to the inner side of the limiting pull plate 2 through a bearing; and the movable ring blocks 22 are symmetrically distributed on the front and rear sides of the hook ring 21, and a U-shaped bolt 5 is screwed on the inner side of the movable ring block 22.

[0020] Working principle: First, fix the tension clamp in the specified position, pull the U-bolt 5 outward to make the conductor pass between the tension clamp body 1 and the U-bolt 5, loosen the U-bolt 5, and the U-bolt 5 is pulled and pressed on the surface of the conductor by the limit hook 3 and the limit pull plate 2. Manually pull the conductor to move the conductor in the tension clamp until the fixed position of the conductor is adjusted, release the pull on the conductor, and the U-bolt 5 is pressed on the surface of the conductor again. Turn the fixing nut 52 on the surface of the U-bolt 5 so that the fixing nut 52 fixes the U-bolt 5 and the tension clamp, ensuring that the conductor between the U-bolt 5 and the tension clamp is firmly fixed, completing the fixation of the conductor by the tension clamp.

[0021] In this embodiment, the right end surface of the U-bolt 5 is sleeved with an anti-slip sleeve 51 , the inner groove wall of the limiting groove block 11 is connected to a connecting slider 42 ; and the right end of the connecting slider 42 is supported and connected to a second spring 43 .

[0022] As a preferred embodiment, the anti-slip sleeve 51 facilitates the U-bolt 5 to press the conductor against the groove surface of the tension clamp body 1 to ensure that the conductor will not separate from the tension clamp body 1 during adjustment; and the tension clamp body 1 is made of aluminum alloy.

[0023] In this embodiment, the lower right edge of the adjusting side plate 4 is connected to the left end of the tension clamp body 1 through a first spring 41, and a rectangular groove is formed on the inner side of the adjusting side plate 4; and a fixing block 33 is clamped in the rectangular groove.

[0024] As a preferred embodiment, the first spring 41 plays a role of auxiliary support for the adjustable side plate 4. The adjustable side plate 4 is connected to the limit hook 3 through the rectangular groove to facilitate the upward and downward movement of the limit hook 3.

[0026] As a preferred embodiment, the screw connection of the adjusting stud 32 rotates, driving the fixing block 33 located in the groove of the adjusting side plate 4 to move up and down through the connecting column 31, thereby driving the limiting hook 3 to move in and out of the hook ring 21.

[0027] In this embodiment, the inner ring surface of the movable ring block 22 is provided with an internal thread; and the movable ring block 22 is connected to the cylindrical external thread of the U-shaped bolt 5 through the internal thread.

[0028] As a preferred embodiment, the movable ring block 22 connects the limit pull plate 2 with the U-bolt 5 through an internal thread, so that the U-bolt 5 is pulled to press the wire on the surface of the tension clamp body 1 to prevent the wire from automatically loosening and detaching.

[0029] In this embodiment, the limiting hook 3 is made of L-shaped aluminum alloy; and the limiting hook 3 is inserted upward into the inner side of the hook ring 21 .

[0030] As a preferred embodiment, the limiting hook 3 is connected to the hook ring 21 by being plugged upward. When the hook ring 21 and the limiting hook 3 need to be separated, the limiting hook 3 can be moved downward out of the hook ring 21.

[0031] In this embodiment, the limiting pull plate 2, the hook ring 21, the movable ring block 22, the limiting hook 3, the adjusting side plate 4 and the second spring 43 constitute a convenient wire pressing structure of the tension clamp body 1.
