The push rod 12, the connecting plate 13 and the second spring 14 form a pushing mechanism for further pushing the protective sleeve 26 to enable the protective sleeve 26 to be tightly sleeved on the curtain rod 25.
When the curtain rods 25 and the protective sleeves 26 are sleeved on the corresponding positioning rods 5, a worker controls the piston rods of the air cylinders 4 to extend, the connecting plate 13, the second springs 14, the sliding seat 3, the positioning rods 5 and the protective sleeves 26 slide towards the curtain rods 25, the deformation amount of the second springs 14 at the stage is negligible, the sliding rods 8 on the two positioning rods 5 firstly collide and press the corresponding first springs 9, the two sliding rods 8 retract into the corresponding positioning rods 5, then under the driving of the connecting rod 11, the four positioning plates 6 on the mounting seat 2 simultaneously outwards expand and support the inner side walls of the curtain rods 25, the four positioning plates 6 on the sliding seat 3 simultaneously outwards expand and support the inner side walls of the protective sleeves 26, and the central axis of the curtain rods 25 and the central axis of the protective sleeves 26 keep coincident. When both the curtain rod 25 and the protective sleeve 26 are supported, the sliding seat 3 will not slide towards the mounting seat 2, and as the piston rod of the air cylinder 4 continues to extend, the connecting plate 13 compresses the second spring 14 and moves the connecting plate 13 towards the sliding seat 3, and the three push rods 12 further push the protective sleeve 26 and finally the protective sleeve 26 is tightly sleeved on the curtain rod 25, so that the curtain rod 25 and the protective sleeve 26 are assembled. When the curtain rod 25 and the protective sleeve 26 are assembled, the worker controls the piston rod of the air cylinder 4 to shrink, the second spring 14 is reset first, the push rod 12 is separated from the protective sleeve 26 and is restored to the initial state, the sliding seat 3 is separated from the mounting seat 2 along with the continued shrinkage of the piston rod of the air cylinder 4, the two first springs 9 eject the corresponding slide rod 8 out of the corresponding positioning rod 5 again, the positioning plate 6 can loosen the curtain rod 25 and the protective sleeve 26 under the driving of the connecting rod 11, and the worker can take away the assembled curtain rod 25 and the assembled protective sleeve 26.
