  • Patent number: 11196241
    Abstract: An integrated opposite hook cable clamp includes a clamping plate, a connecting plate, and at least two J-shaped clamps. Side bars of the J-shaped clamps are locking bars. Locking holes corresponding to the locking bars are provided on the clamping plate, and at least two of the locking holes are diagonally arranged on the clamping plate. The locking bars of the J-shaped clamps vertically pass through the locking holes on the clamping plate and are movably connected with the clamping plate by a locking mechanism. A back surface of the connecting plate is lap-jointed to the inner sides of hooks of each of the J-shaped clamps. A front surface of the connecting plate is opposite to a front surface of the clamping plate (22).
