[0046] A handle 9 is fixedly connected to the top of the support plate 5, and both ends of the main body 1 close to the handle 9 are rotatably connected to moving wheels.

[0047] Working principle:

[0048] When in use, the main body 1 is pushed by the handle 9 to tilt the main body 1 so that the bottom surface of the main body 1 leaves the ground, and the device can be moved by the moving wheels. After the device is moved to the hanging position, the main body 1 is placed vertically so that the bottom surface of the main body 1 contacts the ground.

[0049] The second motor 14 is started, and the output shaft of the second motor 14 rotates forward, driving the sleeve on the telescopic rod 15 to rotate, and the slide bar rotates together, causing the moving block 11 to rotate on the internal thread 10, and the moving block 11 will move upward, driving the sleeve to slide upward on the slide bar, and then the cylinder 24 moves upward, causing the support plate 5 to move upward, and the height of the hoisting assembly is increased.

[0050] When the sleeve rotates, it drives the slide bar to rotate, so that the first bevel gear 16 rotates. The second bevel gear 17 is driven to rotate, so that the screw rod 18 rotates. The screw rod 18 rotates in the threaded hole on the support block 2, and the support block 2 is driven to slide in the slide rail 25.

[0051] The support block 2 slides toward the outside of the main body 1, thereby causing the four support blocks 2 to slide in opposite directions. The support block 2 pulls the slider 22 downward through the connecting plate 3, and the slider 22 slides downward in the first groove 4, thereby lowering the center of gravity of the device and increasing stability.

[0052] The second motor 14 is started, and the output shaft of the second motor 14 is reversed, so that the moving block 11 rotates downward, driving the cylinder 24 and the support plate 5 to move downward, thereby lowering the height of the hoisting assembly.

[0053] Similarly, the support block 2 slides toward the inside of the main body 1, so that the four support blocks 2 slide toward each other, and the slider 22 is also pushed upward through the connecting plate 3. The extension length of the support block 2 is adjusted according to the height of the support plate 5.

[0054] After the support plate 5 is adjusted to a suitable height, the first motor 6 is started to drive the winding roller 8 to rotate, which will change the extension length of the suspension rope, so that the cable can be hoisted by the suspension rope.

[0055] After use, the support block 2 is completely slid into the slide rail 25, and the support plate 5 also moves downward, thereby reducing the volume of the device and facilitating movement or storage.

[0056] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
