The base 21 is a rigid plate with an "L" shape in cross-section and a folded edge. One side of the "L" shaped fold is fixedly connected to a side wall of the outer frame 22 through a bolt 6, and the other side is connected to the outer frame 22. There is a certain gap between the other side walls, so that one surface of the passage 2 forms a circular arc-shaped long groove running through both ends of the passage, that is, the through groove 41 through which the connecting portion 41 of the push clip 4 passes. Wherein, the inlet 221 of the push clip 4 is arranged on the surface of the outer edge of the outer frame 22 . Of course, in other embodiments of the present application, the base 21 may also be a sheet-like structure without folds, and its surface is directly fixed on a side wall of the outer frame 22 by bolts 6 .

Above, the mounting plate 210 is an extension of the outer edge of the fixing section 212 . Among them, there is a gap corresponding to the window 200 of the outer frame 22 between the first section 211 and the fixed section 212, and the gap is used to accommodate the passage of the gear 5; there is a gap corresponding to the entrance 221 between the fixed section 222 and the receiving section 213 , the gap is used to allow the push clip 4 to enter and exit the channel 2; there is a gap corresponding to the window 200 of the outer frame 22 between the receiving section 213 and the end section 214, and the gap is used to accommodate the gear 5 arranged there. . Of course, in other embodiments of the present application, the base 21 may also adopt an integral structure, and it is only necessary to set corresponding avoidance structures at the entrance 221 and the window opening 200 .

When the channel 2 is assembled, the outer frame 22 is respectively fixed on the outer sides of the two bases 21 , so that the through groove 20 formed between the outer frame 22 and the base 21 will be opposite to the inner side of the two channels 2 . Wherein, the inner side of the channel refers to the opposite side of the two bases 21 , and the outer side refers to the side away from the two bases 21 . Windows 200 are provided on the outer surface of the outer frame 22 adjacent to both ends, and the fixing ears 220 are arranged on the outer frame 22 corresponding to the windows 200 , and the fixing ears 220 on the two channels 2 are oppositely arranged. Two ends of the gear shaft 51 are respectively fixed with a gear 5 , and the ends of the gear shaft 51 are respectively fixed on the corresponding fixing ears 220 . The teeth of the ring gear 3 are distributed on the outer edge, and the gear 5 can mesh with the ring gear 3 through the window 200 . In this way, through the coaxial structure of the two gears 5, the two ring gears 3 can be driven to move synchronously.

When the push clip 4 drags the chain clamp to move, the clamp positioned below the flange will fall due to gravity, thereby falling off from the flange surface. In order to prevent the inconvenience caused by this problem, in this embodiment, a supporting plate 8 is fixed on the support 1. The supporting plate 8 is arranged between the two passages 2, one end of which is fixedly connected to the support 1, and the other end is fixed along the passage. The arc track of 2 extends, and the radius of the arc track where the supporting plate 8 is located is larger than the track of the push clamp 4, so that when the push clamp 4 moves around the flange, it will drive the chain clamp to pass through the surface of the supporting plate 8, and the supporting plate 8 will The plate 8 just stops the slide of the chain clamp, thereby supporting the chain links of the chain clamp except the head end link 7 to prevent it from breaking away from the flange surface. In this way, the supporting plate 8 makes the chain clips located at the bottom of the flange surround the surface of the flange, so as to ensure that the head end chain link 7 circles the flange for a week and then docks with the end chain link.
