The second slider 309 is fixedly connected to one side of the connecting rod 304. The second slide groove 3010 is opened on the surface of the rotating frame 306 away from the first slide groove 307. The pulley 3011 is provided at the other end of the connecting rod 304.

[0025] Please refer to this carefully. Figure 4 The drive frame 303 is fixedly connected to the output end of the electric push rod 302, and the output end of the electric push rod 302 in the energized state is used to drive the drive frame 303 to move.

[0026] In this embodiment: the electric push rod 302 is powered on and operated, so that the output end of the electric push rod 302 in operation drives the drive frame 303 to move.

[0027] Please refer to this carefully. Figure 4 The first slider 308 is movably connected to the first slide groove 307, and the second slider 309 is movably connected to the second slide groove 3010.

[0028] In this embodiment: the moving drive frame 303 drives the two first sliders 308 to move inside the two first slide grooves 307 respectively, so the two rotating frames 306 are subjected to force and rotate, and the two connecting rods 304 in the rotating state drive the two second sliders 309 to move inside the two second slide grooves 3010 respectively.

[0029] Please refer to this carefully. Figure 4 The moving drive frame 303 is used to drive the two rotating frames 306 to move, and the two rotating frames 306 in the moving state respectively drive the two connecting rods 304 to move.

[0030] In this embodiment: the two rotating frames 306 rotate under force, and at the same time, the two inclined surfaces of the moving drive frame 303 press against the two pulleys 3011 respectively, causing the two connecting rods 304 to rotate under this pressure.

[0031] Please refer to this carefully. Figure 4 The surface of the drive frame 303 that contacts the pulley 3011 has an inclined surface structure.

[0032] In this embodiment: the two inclined surfaces of the moving drive frame 303 press against the two pulleys 3011 respectively, causing the two connecting rods 304 to rotate under this pressure.

[0033] Please refer to this carefully. Figure 2 The three sets of clamping wheels 305, which are in close proximity, are used to connect and install the air conditioner pipe 1 with the central pipe 2.

[0034] In this embodiment: the two connecting rods 304 in motion drive the two sets of clamping wheels 305 to move towards the air conditioner pipe 1, and at the same time the drive frame 303 in motion drives another set of clamping wheels 305 to move towards the air conditioner pipe 1. Then the three sets of clamping wheels 305 in the close proximity state tightly clamp the air conditioner pipe 1.

[0035] Please refer to this carefully. Figure 3 The sealing mechanism 4 includes a protrusion 401, a groove 402, and a sealing element 403;

[0036] The protrusion 401 is formed at the joint of the air conditioner pipe 1, the groove 402 is formed at the joint of the central pipe 2, the seal 403 is disposed inside the groove 402, and the groove 402 is used for the protrusion 401 to be inserted into its interior.

[0037] In this embodiment: the air conditioner pipe 1 is aligned with the central pipe 2, and then the protrusion 401 is inserted into the groove 402. Under the elastic action of the seal 403, the protrusion 401 is engaged in the groove 402. The engaged protrusion 401 and the groove 402 pre-connect the air conditioner pipe 1 and the central pipe 2.

[0038] Working principle: First, align the air conditioner pipe 1 with the central pipe 2. Then, insert the protrusion 401 into the groove 402. Under the elastic action of the seal 403, the protrusion 401 is engaged in the groove 402. The engaged state of the protrusion 401 and the groove 402 pre-connects the air conditioner pipe 1 and the central pipe 2.

[0039] The electric push rod 302 is then powered on, causing its output end to drive the drive frame 303 to move. The moving drive frame 303 causes the two first sliders 308 to move within the two first sliding grooves 307, resulting in the two rotating frames 306 rotating under force. Simultaneously, the two inclined surfaces of the moving drive frame 303 press against the two pulleys 3011, causing the two connecting rods 304 to rotate under this pressure. The rotating connecting rods 304 then drive the two second sliders 309 to move within the two second sliding grooves 3010, causing the two moving connecting rods 304 to move the two sets of clamping wheels 305 towards the air conditioning duct 1. Simultaneously, the moving drive frame 303 drives another set of clamping wheels 305 towards the air conditioning duct 1. The three sets of clamping wheels 305 tightly clamp the air conditioning duct 1, thus completing the connection and installation of the air conditioning duct 1 and the central duct 2. This structure effectively improves the stability of the installation of the air conditioning duct 1 and the central duct 2.
