When in use, hold the handle with your palm, hook the handle with four fingers, and let the handle face vertically downward to the ground, let the pressure seat plate contact the ground, press the handle with your palm, and push the handle connected to the handle to be compressed by applying pressure with the palm, so that the sliding column fixed sheet connected to the handle applies pressure to the vertical slot plate through the short sliding column, so that the force exerted on the vertical slot plate is guided to the connected pressure hinge plate, and the two pressure hinge plates are squeezed to squeeze the pressure seat plate. The connection point applies pressure to the ground, and the connection points of the two pressure hinge plates and the vertical slot plates are moved away from each other and slide along the outside of the short sliding column to squeeze the elastic thin rod to contract the elastic spring on the outside.

At this time, the cable roll can be placed between the two vertical sliders for positioning. The handle is held by the palm of the hand to apply pressure, so that the two vertical slot plates are moved away from each other. The vertical slot plates move away from each other, so that the cable roll can be easily placed between the two cable rolls, thereby realizing single-person one-handed operation, so that the cable roll can be placed in the specified position. At the same time, the cable roll placed between the vertical sliders will contact the rubber layer On the side, the friction of the contact part with the cable reel is increased through the surface structure of the rubber layer. When the rubber layer is compressed, it will push the wire resistance plate to move, so that the wire resistance plate squeezes the return spring on the outside of the thin sliding rod and approaches the arc-shaped fixed plate. Then, when the arc-shaped fixed plate is compressed, it slides downward along the vertical slot plate to squeeze the contraction spring. When the four fingers hook the handle upward to drive the connected bending connecting rod to move, the bending connecting rod drives the connected vertical slider to slide along the vertical slot plate, so that the cable reel on the inside of the vertical slider moves away from the rubber layer together with it, thereby reducing the friction between the rubber layer and the cable reel, and keeping the wire end taut after being pulled out of the cable reel.

The arc cutting block 75 is slidably connected to the vertical slot plate 54. A groove is provided on the top of the arc cutting block 75, and the groove fits with the bottom end of the vertical slider 56. The guide groove 79 is slidably connected to each group of guide wheels 77 When the arc cutting block 75 fits the bottom of the vertical sliding block 56 through the upper arc groove, the arc cutting block 75 supports the lower support rod 71 through the connecting block hinge rod 74, so that the lower support rod 71 drives the connected hinge support seat 72 to fit with the ground, and the lower support rod 71 drives the connected hinge support seat 72 to provide support for the vertical slot plate 54 as a whole, so that the vertical slot plate 54 can lift the cable reel 4 for unwinding by retracting the turntable 63, and the cable reel 4 can also be placed on the ground for unwinding operation, which can improve the single-person unwinding operation. The efficiency of the wiring and installation of photovoltaic cables is improved. At the same time, the wire led out of the cable reel 4 can be clamped on the inner side of the wire clamp 78. When the wire led out of the cable reel 4 is pulled to the left or right, the led-out wire will slide along the inner side of the wire clamp 78 and drive the guide wheel 77 on the inner side of the connected fixed wheel plate 76 to slide along the guide groove 79 on the upper support rod 73, so that the wire clamp 78 connected to the fixed wheel plate 76 can guide and support the wire led out of the cable reel 4, and prevent the wire from being pulled on the ground and causing wear.

[0032] Working principle: When in use, hold the handle 2 with the palm of your hand, hook the handle 3 with four fingers, and let the handle 1 face the ground vertically downward, let the pressure seat plate 512 contact the ground, and then press the handle 2 with your palm, and push the handle 1 connected to the handle 2 to be pressed by applying pressure with the palm, so that the slide column fixing plate 51 connected to the handle 1 applies pressure to the vertical groove plate 54 through the short slide column 52, so that the force exerted on the vertical groove plate 54 is guided to the connected pressure hinge plate 511, and the pressure hinge plates 511 at two places are pressed and squeezed to press the pressure seat plate 512. The connection between the two pressure hinge plates 511 and the vertical slot plates 54 is pressed against the ground, and the connection between the two pressure hinge plates 511 and the vertical slot plates 54 is moved away from each other and slides along the outside of the short sliding column 52 to squeeze the elastic spring outside the elastic thin rod 53 to contract, and the vertical slot plates 54 are moved away from each other to drive the connected vertical sliders 56 to move away from each other. At this time, the cable roll 4 can be placed between the two vertical sliders 56 for positioning, and the handle 2 is grasped by the hand to apply pressure, so that the two vertical slot plates 54 are moved away from each other. The vertical slot plates 54 are moved away from each other, so that the cable roll 4 can be easily placed between the two vertical sliders 56. The cable reel 4 can be operated by one person with one hand so as to place the cable reel 4 to the specified position. At the same time, the cable reel 4 placed between the vertical sliders 56 will contact the side of the rubber layer 510. The surface structure of the rubber layer 510 increases the friction force of the contact part with the cable reel 4. After the rubber layer 510 is compressed, it will push the wire blocking plate 59 to move, so that the wire blocking plate 59 squeezes the return spring outside the thin slide rod 58 and approaches the arc fixing plate 57. Then, the arc fixing plate 57 is compressed and slides down along the vertical groove plate 54. The spring is squeezed and contracted, and when the four fingers hook the handle 3 upward and lift it up, the connected bending link 55 is driven to move, so that the bending link 55 drives the connected vertical slider 56 to slide along the vertical slot plate 54, so that the cable roll 4 inside the vertical slider 56 moves away from the rubber layer 510 together with it, thereby reducing the friction between the rubber layer 510 and the cable roll 4, so that the wire end is kept tight after being pulled out of the cable roll 4, preventing the cable roll 4 from being entangled with each other after the wiring is loose and needs to be sorted, and reducing the wiring length between photovoltaic panels;

[0033] When the hollow part of the cable roll 4 is aligned with the two shrinking turntables 63 and placed between them, the shrinking turntable 63 will slide along the shaft rod 62 after being compressed, and the fixed ring connecting rod 68 connected to the shaft rod 62 squeezes the V-shaped groove 65 on the side of the pressure block 64 through the pressure ring 69, so that the pressure ring 69 slides along the pressure block 64 to make the pressure block 64 shrink into the shrinking turntable 63. The contraction of the pressure block 64 drives the connected seam plug plate 610 to move together. After the movement, the pressure block 64 squeezes the spring sheet 66 to shrink, so that the spring sheet fixed on the shrinking turntable 63 is The solid block 67 causes the pressure block 64 approaching to squeeze the spring sheet 66 to generate elastic potential energy. After the hollow part of the cable roll 4 is completely placed outside the two retracting turntables 63, the spring sheet 66 releases the elastic potential energy to push the seam plugging plate 610 connected to the pressure block 64 to embed into the hollow part of the cable roll 4 to contact the cable, and the seam plugging plate 610 is used to limit the cable roll 4, and the cable roll 4 is positioned by the retracting turntable 63, so that the cable roll 4 is rotated by the rotating shaft rod 62 connected to the retracting turntable 63 to release the cable, thereby improving the smoothness and efficiency of the cable roll 4.

[0034] When the lifting link 54 is lifted up, the lifting link 54 will be lifted up and the support 50 will be unlocked, and the staff will pull the wire end to make the wire reel 4 unwind. The cable reel 4 is lifted up by retracting the turntable 63 for unwinding, and the cable reel 4 can also be placed on the ground for unwinding operation, thereby improving the efficiency of single-person unwinding and photovoltaic cable wiring installation. At the same time, the wire led out of the cable reel 4 can be clamped on the inner side of the wire clamp 78. When the wire led out of the cable reel 4 is pulled to the left or right, the led-out wire will slide along the inner side of the wire clamp 78 and drive the guide wheel 77 on the inner side of the connected fixed wheel plate 76 to slide along the guide groove 79 on the upper support rod 73, so that the wire clamp 78 connected to the fixed wheel plate 76 guides and supports the wire led out of the cable reel 4, preventing the wire from being pulled on the ground and causing wear.
