In actual use, the partition structure 563 also includes a partition 568 arranged between the movable sleeve 566 and the guide structure 562, which is used to allow the staff to apply a slightly larger force to cross over; and the spring ring 564, the fixed sleeve 565 and the movable The sleeve 566 is used to trap the rewinding shaft, and allow the rewinding shaft to move left and right in a small range for adjustment during rewinding, so as to achieve the effect that the rewinding shaft can be adaptively adjusted according to the deviation of the material and other factors.

Specifically, a clamping block 567 is provided between the fixed sleeve 565 and the movable sleeve 566. The clamping block 567 has a groove for accommodating the spring ring 564, and the two sides of the spring ring 564 abut the movable sleeve 566 and the fixed sleeve 565 respectively. It has the effect of positioning the spring coil 564, ensuring that the movable sleeve 566 can be reset under the reset force of the spring coil 564 after being offset.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as above with the preferred embodiment, it is not used to limit the utility model. Anyone who is familiar with the utility model Professional technicians, without departing from the scope of the technical solution of the present utility model, should use the technical content disclosed above to make some changes or modify equivalent embodiments with equivalent changes, but if they do not depart from the technical solution of the present utility model, the The utility model technology refers to any simple modification, equivalent change and modification made to the above embodiments, which all belong to the scope of the utility model technical solution.
