It should be noted that when the first screw is tightened, the first screw will pull the first clamp arm 21 and the second clamp arm 22 together, thereby generating a clamping force. In this way, it can be ensured that the insulating shield 1 will not fall off or move during the installation process, thereby improving the accuracy and reliability of the installation.

It should be noted that in order to adapt to the insulation shield 1 of different lengths or sizes, the bogie 31 can be designed to be adjustable in length, such as setting an adjustable length connecting rod at a section of the second bracket 313 close to the universal ball 311, and changing the overall length of the bogie 31 by adjusting the length of the connecting rod. In this way, it is ensured that the insulation shield 1 can remain relatively stable during the installation process, and at the same time, flexible rotation capability is provided when necessary.

[0040] In one embodiment, the spherical groove 321 is provided with a second screw hole, and a second screw 323 is inserted into the second screw hole. It should be noted that when the second screw 323 is tightened, the second screw 323 will push the universal ball 311 to abut against the spherical groove 321, so that the relative position of the universal ball 311 and the spherical groove 321 is fixed. In this way, an additional fixing force can be provided for the connection between the connecting seat 32 and the universal ball 311, and the angle adjustment can be achieved to prevent the connection from loosening or falling off due to vibration or external force during the installation process, thereby enhancing the stability of the entire installation tool. At the same time, when the connecting seat 32 or the universal ball 311 is worn or damaged, the user can repair the connection by simply replacing it, which simplifies the maintenance process and reduces the maintenance cost.

[0041] In one embodiment, the connection groove 322 is provided with a third screw hole, and a third screw 324 is inserted into the third screw hole. It should be noted that when the third screw 324 is tightened, the third screw 324 will push the insulating rod 33 to abut against the connection groove 322, so that the relative position of the insulating rod 33 and the connection groove 322 is fixed. As a result, the connection stability between the insulating rod 33 and the connection seat 32 is significantly enhanced, and the connection is prevented from loosening or falling off due to vibration or external force during the installation process, thereby improving the reliability and safety of the entire installation tool, and at the same time, improving work efficiency and convenience.
