By changing the traditional sleeve head, a "I"-shaped third sleeve 50 is designed, which can better adapt to the bolt head of the drainage wire clamp 59, and then the torque is transmitted to the bolt of the drainage wire clamp 59 under the action of the third sleeve 50. At this time, the bolt of the drainage wire clamp 59 will move up, and the second impact wrench 57 also moves up under the action of the electric push rod 58, so that the drainage wire clamp 59 can be clamped to the cable.

[0058] In an embodiment of the present invention, Figure 5As shown, a mounting flap unlocking mechanism 60 is also provided at the top of the mounting frame 53, and the drainage wire clamp 59 is located in the inner cavity of the mounting flap unlocking mechanism 60, and the drainage wire clamp 59 is abutted against the inner wall of the mounting flap unlocking mechanism 60 (the inner wall of the mounting flap unlocking mechanism 60 is provided with mutually symmetrical flanges at the upper and lower parts, and the drainage wire clamp 59 is abutted through the symmetrical flanges).

Thus, the drainage clamp 59 can be effectively mounted on the cable through this device. When the entire device is installed and removed, it is only necessary to drive the first drive motor 69 or manually pull the handle 641 (the handle 641 can serve as another unlocking method when the first drive motor 69 encounters an abnormality, such as when it cannot be started), and the device can be disengaged with one click under the action of the torsion spring 62.
