Then, according to the size of the air conditioner indoor unit, the bidirectional threaded rods 11 on the two groups of bottom support frames 1 are rotated. When the bidirectional threaded rods 11 rotate, two angle support frames 12 on the two groups of bottom support frames 1 are driven to move relative to each other, so as to adjust the spacing, and further adjust the length of the installation frame. Then, by pulling the clamping plate 22 of the clamping part 2 to slide on the middle plate 21, the length of the clamping part 2 is adjusted, and further the width of the installation frame is adjusted, so that the entire installation frame can be adapted to place air conditioner indoor units of various specifications by using the supporting feet 121. After the air conditioner indoor unit is clamped and rotated in the installation frame, by screwing the nut sleeve 62, the nut sleeve 62 drives the pressing clamping plate 61 to move downward along the external thread sleeve 42 under the restriction of the limit groove 402 until the air conditioner indoor unit is pressed and fixed inside the installation frame. When disassembly is required, only need to reverse the nut sleeve 62 and pull up the pressing clamping plate 61, making the installation and disassembly of the air conditioner indoor unit very convenient. Then, by pulling the lifting rod 43 to extend on the external thread sleeve 42, and then screwing the pin rod one 421 into the pin hole one 401 for fixation, making it flush with the top of the arched greenhouse steel frame. Then, by pulling out the extension rod 45 from the support sleeve 44, the main clamping jaw 46 is attached to the arched greenhouse steel frame. Then, the main clamping jaws 46 on the two groups of main suspension assemblies 4 are fixed together with screws and clamped on the arched greenhouse steel frame to complete the main suspension installation;

[0035] Then, pull the main screw rod 31 to rotate a certain angle, and then screw the connecting sleeve 32 to slide on the main screw rod 31, slide the suspension rod 33 close to both sides of the arched greenhouse steel frame. Then, screw the secondary screw rod 34 to extend from the suspension rod 33, and then flip the two side clamping jaws 36 to clamp the greenhouse steel frame. Then, screw the locking nut 37 to fix and lock the two side clamping jaws 36 together to complete the side suspension fixation;

[0036] Furthermore, place the HVAC pipe on the fixed ring 52. After being connected to the air conditioner indoor unit, the sliding sleeve 51 can slide along the lifting rod 43 by using the pin rod three 511 to adjust the height, which is convenient for the butt joint installation of the HVAC pipe. Then, flip the movable ring 53 and use bolts to clamp the HVAC pipe on the fixed ring 52. And through the opening of the wire clamping hole 501, the cables connected to the air conditioner indoor unit can be further fixed and restricted, which is convenient for the entire air conditioner to be suspended and installed inside the greenhouse.
