[0043] Referring to Figure 1 and Figure 4 , the second shaft body 1-3 is threadedly connected to the first shaft body 1-1, so that the relative rotation of the two also causes the axial relative movement. More specifically, the two ends of the first shaft body 1-1 can be fixedly connected with the same nut 1-1b; the two ends of the second shaft body 1-3 are stepped, and the smaller diameter part has an external thread, which is threaded out from the two ends of the first shaft body 1-1 and is threadedly connected to the nut 1-1b. The threaded part can also be detachably connected with a handle 1-3a.

[0044] Referring to Figure 1 and Figure 2 , the plurality of sets of supporting modules 1-2 are installed in the plurality of sets of first grooves 1-1a one by one, that is, one set of supporting modules 1-2 is also circularly arrayed around the axis of the first shaft body 1-1. The plurality of sets of supporting modules 1-2 are driven to radially expand and contract by the axial relative movement between the second shaft body 1-3 and the first shaft body 1-1.

[0045] Initially, the plurality of sets of supporting modules 1-2 are in a relatively retracted position, and the winding drum is sleeved into the first shaft body 1-1. The relative rotation of the second shaft body 1-3 and the first shaft body 1-1 causes the axial relative movement of the second shaft body 1-3 and the first shaft body 1-1, which in turn drives the plurality of sets of supporting modules 1-2 to expand until they abut against the inner wall of the winding drum, thereby fixing the winding drum on the first shaft body 1-1.

[0046] Referring to Figure 5 , in some embodiments, each supporting module 1-2 comprises a fixed part 1-2-1, a movable part 1-2-2 and an elastic member 1-2-3. The second shaft body 1-3 is fixedly provided with a circular table body 1-3b corresponding to the position of each set of first grooves 1-1a.

[0048] The movable part 1-2-2 can be radially telescoped relative to the first groove 1-1a, and more specifically, the movable part 1-2-2 is also stepped, with the smaller part extending from the fixed part 1-2-1.

[0049] The elastic member 1-2-3 is used to keep the movable part 1-2-2 against the surface of the circular truncated cone 1-3b, and more specifically, the elastic member 1-2-3 can be a compression spring, the fixed part 1-2-1 has a groove for the elastic member 1-2-3 to be inserted into, and the other end of the elastic member 1-2-3 is against the larger part of the movable part 1-2-2; the bottom surface 1-2-2a of the larger part is an inclined plane, and the slope of the inclined plane is matched with the circular truncated cone 1-3b, and the surface of the circular truncated cone 1-3b is in line contact with the inclined plane.

[0050] The second shaft body 1-3 can be threadedly connected to the first shaft body 1-1 first, and the position is adjusted so that the circular truncated cone 1-3b is one-to-one corresponding to the plurality of groups of first grooves 1-1a; and then the jacking module 1-2 is installed into the first groove 1-1a. The assembly is relatively simple and convenient.

[0051] Please refer to Figure 1 and Figure 2 In some embodiments, the circular array of the two adjacent groups of first grooves 1-1a is staggered, that is, the circular array of the two adjacent groups of jacking modules 1-2 is also staggered.
