A sliding rod 16 is installed between the two symmetrically arranged support blocks 15. The support blocks 15 and the connecting plate 14 are bolted together. The sliding rod 16 is made of Q235A steel material. A rope passes through the fixed pulley 13 between each group of support plates 12 on the box body 11. When the rope is pulled, the rope pulls the box body 11 upward through the fixed pulley 13. The upward movement of the box body 11 drives the sliding rod 16 between the symmetrical support blocks 15 on the connecting plate 14 to move upward;

[0026] In this embodiment: the clamping assembly includes a fixed plate 21, a telescopic rod 25 is provided at one end of the fixed plate 21, a back pressure plate 24 is provided on the telescopic rod 25, a spring 22 is installed on the circumference of the telescopic rod 25, a joint 23 is provided on the back pressure plate 24, the back pressure plate 24 is circular, with a diameter of 10 cm, and the travel of the telescopic rod 25 is 20 cm. The joint 23 presses the spring 22 through the back pressure plate 24 under the obstruction of the fixed plate 21, and the telescopic rod 25 is shortened under the push of the back pressure plate 24. After the spring 22 is released, the telescopic rod 25 is driven by the back pressure plate 24 to push the joint 23 to drive the connecting frame 31;

[0027] In this embodiment: the placement component includes a connecting frame 31, a slider 32 is installed on the bottom surface of the connecting frame 31, two clamping frames 33 are arranged on the bottom surface of the slider 32, a handle 34 is arranged on one side of the clamping frame 33, a supporting plate 37 is installed on the bottom side of the clamping frame 33 away from the handle 34, and an anti-slip pad 36 is arranged on the supporting plate 37, an extension frame 38 is arranged below the handle 34, and universal wheels 35 are respectively arranged at both ends of the extension frame 38, the handle 34 and the clamping frame 33 are welded together, and the clamping frame 33 on the slider 32 is pulled to both sides by the handle 34, the clamping frame 33 drives the supporting plate 37 and the anti-slip pad 36 thereon to move to both sides of the air-conditioning outdoor unit, the supporting plate 37 is inserted from both sides of the bottom of the air-conditioning outdoor unit, and the universal wheels 35 on the extension frame 38 enable the air-conditioning outdoor unit to move along the wall at a fixed distance during the hoisting process.

[0028] Working principle: Pass the rope through the fixed pulley 13 between each group of support plates 12 on the box body 11, pull the handle 34 to both sides to drive the slider 32 on the clamping frame 33 to move along the slide rod 16, and the slider 32 drives the connecting frame 31 to push the back pressure plate 24 through the joint 23. The spring 22 is compressed and tightened under the push of the back pressure plate 24 and the obstruction of the fixed plate 21. At the same time, the telescopic rod 25 is shortened under the push of the back pressure plate 24. Move the clamping frame 33 to both sides of the air conditioner outdoor unit, slowly release the handle 34, and after the spring 22 is released, it drives the telescopic rod 25 through the back pressure plate 24 to push the joint 23 to drive the connecting frame 31. The connecting frame 31 uses the slider 32 to insert the supporting plate 37 on the clamping frame 33 from both sides of the bottom of the air-conditioning outdoor unit, and pulls the rope. The rope pulls the box body 11 upward through the fixed pulley 13. The upward movement of the box body 11 drives the sliding bar 16 between the symmetrical support blocks 15 on the connecting plate 14 to move upward. The sliding bar 16 pulls the supporting plate 37 on the clamping frame 33 upward through the slider 32. The supporting plate 37 moves upward to lift the air-conditioning outdoor unit. The anti-slip pad 36 prevents the air-conditioning outdoor unit from sliding during the process of hanging the air-conditioning outdoor unit. The universal wheel 35 on the extension frame 38 enables the air-conditioning outdoor unit to move along the wall at a fixed distance during the hoisting process.
