Thus, the transmission rod 6 drives the bottom end of the clamping arm 7 to move. At the same time, the connecting arm in the middle of the clamping arm 7 is connected to the fixed frame 2, thereby limiting the clamping arm 7. The transmission rod 6 drives the bottom end of the clamping arm 7 to move left and right, thereby fixing the cable.
