The frame 1 has casters on its underside, which can be two directional casters 24 and two omnidirectional casters 25, allowing the trolley to move more flexibly. A lifting frame 2 is mounted on the frame 1. A sliding groove is provided inside the lifting frame 2, and a mounting frame 4 is disposed on the sliding groove. The mounting frame 4 can move up and down along the sliding groove. The mounting frame 4 is driven to rise and fall by a hydraulic device 7, replacing manual labor. The hydraulic device 7 is a hydraulic cylinder mounted on the frame 1. Two guide rails 5 are provided on the mounting frame 4, which are parallel to each other and spaced apart, and are horizontally arranged. The mounting frame 4 is equipped with a clamping device, which includes clamping rods 6. The clamping rods 6 are L-shaped and consist of two rods. The short sides of the two clamping rods are provided with sliding tracks 18. The clamping rods 6 are mounted on the guide rails 5 of the mounting frame 4 and can move left and right along the guide rails 5. The mounting frame 4 has two sides respectively... A screw seat 17 is provided, located between two guide rails 5. Two screws 16 are provided, each passing through the screw seat 17. One end of each screw 16 is connected to the short side of the clamping rod 6, and the screws 16 and clamping rod 6 are rotatably connected. The other end is provided with a rotary valve 15 for driving the screws 16 to rotate. The rotary valve 15 can drive the screws 16 to rotate in the screw seat 17. During rotation, the screws 16 move along the threads in the screw seat 17, thereby driving the clamping rod 6 to move within the screw seat 17. The guide rail 5 moves horizontally, and the two clamping rods 6 are used to clamp the air duct box. The upper side of the mounting frame 4 is equipped with an air duct clamping device, which includes an air guide pipe 11. The air guide pipe 11 is fixed on the connecting plate 10.
