[0027] See also Figure 1-4 , the utility model provides an embodiment: a phase-to-phase insulation isolation device for live working on a distribution line, comprising a mother pole 1, a limiting mechanism 8 and an adjusting mechanism 9, fixed slots 7 are provided on both sides of the mother pole 1, a sub-pole 2 is movably provided inside the fixing slot 7, the number of the sub-pole 2 is two, the number of the fixing slots 7 is two, an adjusting mechanism 9 is provided inside the sub-pole 2, the adjusting mechanism 9 comprises a mounting cavity 901, and the mounting cavity 901 is provided at both ends of the sub-pole 2, a limiting hole 903 is provided at one end of the two mounting cavities 901 away from each other, a limiting block 904 is movably provided inside the limiting hole 903, and the ends of the two limiting blocks 904 close to each other are fixedly connected to a movable plate 905, and the ends of the two movable plates 905 close to each other are fixedly connected to a second spring 902;

[0028] Specifically, such as Figure 1 、 Figure 2 and Figure 4 As shown, during use, when the distance between the two sub-rods 2 needs to be adjusted, the limit block 904 can be pressed to move the limit block 904 in the direction away from the limit hole 903 and close to the installation cavity 901. When the limit block 904 moves to the appropriate position, the shaped plate 3 is pulled to drive the sub-rod 2 to move, and the movement of the sub-rod 2 drives the limit block 904 to move. When the limit block 904 moves to the opposite side of the other set of limit holes 903, the second spring 902 is no longer subjected to external force, and will drive the limit block 904 to insert into the limit hole 903, thereby completing the fixation of the sub-rod 2. By adapting the limit block 904 to the limit holes 903 in different positions, the length of the sub-rod 2 in the fixing groove 7 can be adjusted, thereby achieving the purpose of adjusting the distance between the two sub-rods 2, thereby better meeting daily use needs, and solving the problem that the distance between the two sub-rods 2 is relatively fixed, it is difficult to reasonably adjust the insulation isolation distance of the line according to needs, and it is difficult to well meet daily use needs.

[0029] On both sides of the two sub-rods 2 away from each other, there are fixedly connected with U-shaped plates 3. The top and bottom of the U-shaped plates 3 are provided with limiting mechanisms 8. The limiting mechanism 8 includes a sleeve 801. An active plate 802 is movably arranged inside the sleeve 801. One ends of the two active plates 802 away from each other are fixedly connected with a pull rod 806. And one end of the pull rod 806 penetrates through the sleeve 801 and extends to the outside of the sleeve 801. A first spring 805 is sleeved on the outer wall of the pull rod 806. One ends of the two pull rods 806 away from each other are fixedly connected with a pull block 804. Fixing holes 803 are opened at one ends of the two active plates 802 close to each other. A fixing rod 807 is movably arranged inside the fixing hole 803. And the fixing rod 807 is fixedly connected with the active plate 802. Sliding grooves 6 are opened on the outer walls of the two U-shaped plates 3 away from each other. A mountain-shaped plate 4 is movably arranged inside the sliding groove 6. Arc-shaped abutting blocks 5 are fixedly connected to one sides of the two mountain-shaped plates 4 close to each other;

[0030] Specifically, as Figure 1 、 Figure 2 and Figure 3 shown, when in use, the cable can be placed into the U-shaped plate 3, then the mountain-shaped plate 4 is aligned with the sliding groove 6, and then the mountain-shaped plate 4 is moved so that the mountain-shaped plate 4 moves in the direction close to the cable until the arc-shaped abutting block 5 contacts the cable, thus completing the fixing of the cable. At the same time, the pull block 804 can be pulled. The pull block 804 moves to drive the active plate 802 to move through the pull rod 806, and the movement of the active plate 802 drives the fixing rod 807 to disengage from the fixing hole 803. Then the mountain-shaped plate 4 is moved. The movement of the mountain-shaped plate 4 drives the arc-shaped abutting block 5 to move. When the arc-shaped abutting block 5 moves to a suitable position, the pull block 804 is released. At this time, the elasticity of the first spring 805 can be utilized to drive the fixing rod 807 to insert into the fixing hole 803, thus completing the fixing of the U-shaped plate 3. By adapting the fixing rod 807 to the fixing holes 803 at different positions, the position of the arc-shaped abutting block 5 can be adjusted, so that cables with different diameters can be fixed, thereby improving the practicability of the device.

[0031] When the limit block 904 is pressed against the limit hole 903, the limit block 904 can be moved in the direction away from the limit hole 903 and close to the installation cavity 901. When the limit block 904 moves to the appropriate position, the shape plate 3 is pulled to drive the sub-rod 2 to move, and the movement of the sub-rod 2 drives the limit block 904 to move. When the limit block 904 moves to the opposite side of the other set of limit holes 903, the second spring 902 is no longer subjected to external force, which will drive the limit block 904 to insert into the limit hole 903, thereby completing the fixation of the sub-rod 2. By adapting the limit block 904 to the limit holes 903 in different positions, the length of the sub-rod 2 in the fixing groove 7 can be adjusted, thereby achieving the purpose of adjusting the distance between the two sub-rods 2, thereby better meeting daily usage needs. Secondly, the cable can be placed in the shape plate 3, and then the shape plate 3 is pulled. The plate 4 is aligned with the sliding groove 6, and then the mountain-shaped plate 4 is moved so that the mountain-shaped plate 4 moves in the direction close to the cable until the arc-shaped abutment block 5 contacts the cable, thereby completing the fixation of the cable. Finally, by pulling the pulling block 804, the pulling block 804 moves through the pulling rod 806 to drive the movable plate 802 to move, and the movable plate 802 moves to drive the fixing rod 807 to disengage from the fixing hole 803, and then move the mountain-shaped plate 4, and the mountain-shaped plate 4 moves to drive the arc-shaped abutment block 5 to move. When the arc-shaped abutment block 5 moves to the appropriate position, release the pulling block 804. At this time, the elasticity of the first spring 805 can be used to drive the fixing rod 807 to be inserted into the fixing hole 803, thereby completing the fixation of the shaped plate 3. By adapting the fixing rod 807 to the fixing holes 803 in different positions, the position of the arc-shaped abutment block 5 can be adjusted, so that cables of different diameters can be fixed, thereby improving the practicality of the device.
