When working, the bracket structure composed of the transmission base 1, fasteners, connecting parts, bottom plate 2, movable seat 4, transmission shaft 14 and connecting shaft 5 can be supported on both sides of the roller respectively, and the front end of the connecting shaft 5 is inserted into the inside of the roller to support the roller. When the roller needs to be disassembled, there is no need to disassemble the transmission base 1 from the knitting machine, but to disassemble the first bolt 12 and the second bolt 13, and then rotate the connecting plate 11 to disengage the connecting plate 11 from the transmission shaft 14, and then control the movable seat 4 to move away from the roller for convenience. After separation, the roller is taken out naturally to complete the disassembly operation of the roller. In addition, the baffle 8 can block the front side of the movable seat 4. At this time, the existence of the baffle 8 can, on the one hand, prevent the movable seat 4 from being disengaged from the bottom plate 2, and on the other hand, with the cooperation of the first bolt 12, the movable seat 4 can be firmly connected to the baffle 8, so that the movable seat 4 is stably located at the upper end of the bottom plate 2. In this way, the movable seat 4 is used in cooperation with the connecting shaft 5 to support the roller more stably.

[0022] Furthermore, the upper end surfaces of the transmission base 1 and the bottom plate 2 are provided with mounting holes 10. During operation, the bracket structure can be fixedly mounted in the knitting machine by the multiple mounting holes 10.

[0025] Working principle:

[0026] When in use, the bracket structure composed of the transmission base 1, fasteners, connectors, base plate 2, movable seat 4, transmission shaft 14 and connecting shaft 5 can be supported on both sides of the roller respectively, and the front end of the connecting shaft 5 is inserted into the interior of the roller to support the roller. When the roller needs to be disassembled, there is no need to disassemble the transmission base 1 from the knitting machine, but remove the first bolt 12 and the second bolt 13, and then rotate the connecting plate 11 to disengage the connecting plate 11 from the transmission shaft 14, and then control the movable seat 4 to move away from the roller. After separation, take out the roller and complete the disassembly operation of the roller. Since the transmission base 1 does not need to be disassembled and moved, there is no need to reinstall the transmission base 1 in the knitting machine, which is more convenient.
