A spiral spring 56 is provided on the inner side of the rope-releasing shell 55, and a rotating ring 594 is fixedly connected to one end of the spiral spring 56 close to the inner side. The rotating ring 594 is slidably connected to the inside of the rope-releasing shell 55, and the rotating ring 594 is fixedly connected to a rotating wheel 593, and a ratchet 592 is fixedly connected to the side of the rotating wheel 593 away from the rope 57.

[0032] The rope 57 is fixedly connected at one end close to the middle portion and fixedly connected to the end of the spiral spring 56 away from the middle portion, and a ratchet 591 is fixedly connected to the bottom of the adjustment cap 59.

[0033] Working process: For horizontal installation of insulation panels:

[0034] Place the tool near the center of the insulating board, and manually adjust the third fixing rod 4 according to the shape of the insulating board so that the third fixing rod 4 can be adjusted left and right along the slide groove 51, and then fix the insulating board through the fixing piece 3, and then fix it through the rope, hook 52, and rope lock 58, and lift it upward through the rope, and use the hook 52 and rope lock 58 to lift the insulating board upward, observe the horizontal inclination angle of the insulating board, and release the fixation of the fixed circular plate 54 to the rope release housing 55 by rotating the fixed circular plate 54, and manually rotate the fixed circular plate 54 to adjust the position of the rope release housing 55, and apply forces in different directions to the insulating board through different angles so that the insulating board maintains a horizontal angle, and then adjust the adjusting cap 59, and the adjusting cap 59 drives the ratchet 591 to move, and the restriction on the ratchet 592 makes the rope lock 58 is subjected to the pulling force of the rope, so that the rope lock 58 moves upward, and the rope lock 58 drives the rope 57 to stretch. The end of the rope 57 close to the inner side pulls the spiral spring 56. Under the influence of the force, the spiral spring 56 drives the rotating wheel 593 to rotate, and the rotation of the rotating wheel 593 drives the rotating ring 594, but the rotating ring 594 is restricted by the ratchet 592, so that one end of the spiral spring 56 is fixed, so that the spiral spring 56 shrinks inward, and the rotating wheel 593 is used to bind the rope 57 to prevent the rope 57 from being tangled and causing the rope 57 to be knotted. The rope 57 is stretched to a suitable position, and the adjusting cap 59 is adjusted again, and the ratchet 591 is used to jam the ratchet 592, so that the rope 57 stops stretching. At the same time, the spiral spring 56 remains in a contracted state.

[0035] For vertical installation:

[0036] Manually adjust the third fixing rod 4 to move toward the side close to the second fixing rod 2, then fix the insulating plate through the fixing part 3, select the rope-releasing housing 55 on the second fixing rod 2 away from the third fixing rod 4, rotate the fixing circular plate 54 to release the restriction of the rope-releasing housing 55, rotate the rope-releasing housing 55 to make the rope lock 58 vertical, adjust the position between the two rope-releasing housings 55, rotate the fixing circular plate 54 again to fix the position of the rope-releasing housing 55, fix it with the rope and the rope lock 58, and then limit it with the adjusting cap 59, adjust the vertical angle of the insulating plate port by controlling the elongation of the rope 57, and then limit the current state of the spiral spring 56 with the adjusting cap 59.

[0037] When the installation is completed, the adjusting cap 59 is adjusted to release the restriction of the ratchet 592, thereby utilizing the force of the spiral spring 56 itself to shrink the rope 57 to its original position.
