[0036] The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0037] like Figure 1-6 As shown, an installation tool for installing a live operating wire clamp comprises an insulating outer tube 1, an inner tube 2, an operating rod 3, a fixed clamp 4, a movable clamp 5, a guide column 6, and a reset elastic member 7.

[0038] The insulating outer tube 1 can be made of insulating material, or an insulating sleeve made of insulating material can be provided on its outside to achieve the purpose of insulation. The insulating outer tube 1 is a hollow tube, and a guide groove 101 is formed on its side wall. The guide groove 101 includes a longitudinal section and a transverse section. The transverse section is located at the upper end of the longitudinal section, and the whole is in the shape of a "7".

[0039] The inner tube 2 is arranged inside the insulating outer tube 1 , and its outer diameter is matched with the inner diameter of the insulating outer tube 1 , so that the inner tube 2 can slide axially or rotate circumferentially inside the insulating outer tube 1 .

[0040] The operating rod 3 passes through the guide groove 101 and is fixedly connected to the inner tube 2, and the inner tube 2 can be driven by the operating rod 3. There are many options for the specific connection between the operating rod 3 and the inner tube 2, such as forming a threaded hole on the side wall of the inner tube 2, and the operating rod 3 is fastened with it by threads.

[0041] The fixing chuck 4 is fixedly installed on the upper end of the insulating outer tube 1. The fixing chuck 4 includes a first clamping portion 401, a mounting portion 402, and a connecting portion 403 connecting the mounting portion 402 and the first clamping portion 401. The first clamping portion 401 is located at the upper end of the connecting portion 403, and is a card slot structure protruding to one side of the connecting portion 403. The mounting portion 402 is located at the lower end of the connecting portion 403, and protrudes to the other side of the connecting portion 403, so that the fixing chuck 4 is a "Z"-shaped structure as a whole. A mounting column 405 is formed at the bottom of the mounting portion 402. The mounting column 405 is inserted into the insulating outer tube 1 and fixedly connected to the insulating outer tube 1 through a pin shaft 406. It is easy to install and the overall stability and reliability. The connecting portion 403 is formed with a longitudinally arranged slide groove 404.

[0042] The movable clamp 5 passes through the slide slot 404 and slides with the slide slot 404 , one end of which is bent upward to form a second clamping portion 501 corresponding to the first clamping portion 401 , and the other end is fixedly connected to the guide column 6 .

[0043] The upper end of the guide column 6 is fixedly connected to the movable clamp 5, and the lower end passes through the mounting portion 402 and the mounting column 405 of the fixed clamp 4 and then extends into the insulating outer tube 1. A spring seat 601 is installed at the lower end of the guide column 6. The spring seat 601 is adapted to the inner diameter of the insulating outer tube 1 and can slide axially along the insulating outer tube 1. The lower end of the spring seat 601 abuts against the inner tube 2.

[0044] Among them, external thread structures are formed at both ends of the guide column 6, and the two ends of the guide column 6 and the movable clamp 5 and the spring seat 601 are fixed and locked by nuts.

[0045] The reset elastic member 7 is a spring and is sleeved outside the guide column 6. The two ends of the reset elastic member 7 are respectively against the spring seat 601 and the mounting column 405, which can drive the spring seat 601 downward. The spring seat 601 can drive the inner tube 2 and the movable clamp 5 to move downward to achieve reset.

[0046] like Figure 7 As shown, a live operating wire clamp includes a main frame 11, wherein the main frame 11 is provided with two first mounting positions 12 and second mounting positions 13 arranged in parallel, wherein positioning bosses 121 are protruded from the upper and lower ends of the outer side wall of the first mounting position 12, wherein a first screw 122 threadedly matched therewith is provided below the first mounting position 12, wherein the upper end of the first screw 122 extends into the first mounting position 12 and a first wire pressing block 123 is movably installed thereon; wherein an opening 131 is provided on the outer side wall of the second mounting position 13, wherein a second screw 132 threadedly matched therewith is provided below the second mounting position 13, wherein the upper end of the second screw 132 extends into the second mounting position 13 and a second wire pressing block 133 is movably installed thereon.

[0047] When installing the above-mentioned live operating wire clamp, in addition to the above-mentioned installation tools, an insulating long rod with a wrench is also required, preferably a wrench structure that can be remotely operated and automatically actuated. It is an existing tool equipment and its structure is not introduced here.

[0048] The specific steps for installing the live operation clamp are as follows:

[0049] 1) First, pass the lead wire through the first installation position 12, and then rotate the first screw rod 122 to push the first wire pressing block 123 to press and fix the lead wire;

[0050] 2) The positioning boss 121 at the upper end of the first mounting position 12 on the live operating wire clamp is matched with the first clamping portion 401 of the fixed clamp 4 on the installation tool, and then the operating rod 3 is pushed to move along the longitudinal section of the guide groove 101, and the driven movable clamp 5 moves upward, so that the positioning boss 121 at the lower end of the first mounting position 12 on the live operating wire clamp is matched with the second clamping portion 501 of the movable clamp 5, and then the operating rod 3 is pushed to move along the transverse section of the guide groove 101 to lock it. Figure 8-9 As shown;

[0051] 3) Hold the insulating outer tube 1 and lift the live operating wire clamp, and align the opening 131 of the second mounting position 13 on the live operating wire clamp with the wire, and hang the second mounting position 13 on the wire through the opening 131;

[0052] 4) The second screw rod 132 is rotated by the insulating long rod with a rotating wrench, so that the second wire pressing block 133 presses and fixes the wire, thereby realizing a reliable connection between the live operation wire clamp and the wire;

[0053] 5) The operating rod 3 is moved horizontally by the insulating long rod. When the operating rod 3 slides to the longitudinal section of the guide groove 101, it is automatically reset and unlocked under the drive of the reset elastic member 7, and finally the installation tool is removed.

[0054] like Fig.10 As shown, the lower end of the insulating outer tube 1 is detachably connected to a plurality of extension tubes 9, and the insulating outer tube 1 and the extension tubes 9 can be connected by threads, so that the extension tubes 9 can be added to extend the tube according to a specific height.

[0055] The above-mentioned installation tool can reliably clamp and fix the live operating wire clamp. When installing the live operating wire clamp, it is convenient to stabilize the position of the live operating wire clamp, which is beneficial to the installation operation of the operator. After the installation is completed, the operating lever can be easily moved through its 7"-shaped guide groove structure, so that the installation tool can be easily separated from the live operating wire clamp. The above-mentioned scheme makes the installation operation of the live operating wire clamp very convenient and can greatly improve its installation efficiency.
