Detailed ways

As shown in Fig. 1 and Fig. 4, the present invention is a wire take-up mechanism that can change the outer diameter, including a winding shaft (not shown in the figure), an inner disk 2, an outer disk 3 and a winding seat 4.

The winding seat 4 is installed between the inner disk 2 and the outer disk 3, and the center of the inner disk 2 is fixedly sleeved on the winding shaft. The center of the inner wall of the outer disk 3 is provided with a fixed rod 31 , the fixed rod 31 is inserted in the center of the inner disk 2 and the bayonet 32 on the fixed rod 31 is engaged in the connecting groove 462 of the shifting block 46 .

As shown in Fig. 2 and Fig. 3, the described winding seat 4 includes a left movable disc 41, a right movable disc 42, a fixed disc 43, a return spring 44, a shifting block 46, a left eccentric block 47, a right eccentric block 48, a left Top block 49, right top block 410. The left movable disk 41, the right movable disk 42 and the fixed disk 43 are all arc-shaped disks and connected successively to form an annular disk. The right end of the left movable disk 41 is hinged on the inner disk 2 and is connected with the left end of the fixed disk 43. The left end of the left movable disk 41 is connected with the left end of the right movable disk 42, the right end of the right movable disk 42 is hinged on the inner disk 2 and connected with the right end of the fixed disk 43, and the two ends of the back-moving spring 44 are respectively connected to the left movable disk 41 and the right On movable plate 42; Described shifting block 46 is fixed on the bobbin shaft that penetrates the center of winding seat 4, on the outer wall of shifting block 46, a shift fork 461 is installed radially, and the outer end face of shifting block 46 is provided with multiple A connecting groove 462, the inner end surface of the shifting block 46 fixes the left eccentric block 47 and the right eccentric block 48 successively, the left top block 49 is fixed on the free end inner side of the left movable plate 41 and abuts against the left eccentric block 47, and the right top block 410 It is fixed on the inner side of the free end of the right movable disc 42 and abuts against the right eccentric block 48. A limit block 411, 412 is respectively arranged at the inner side two ends of the left movable disc 41, and the shift fork 461 on the shifting block 46 is on the two Move between a limit block 411,412.

It should be noted that in this embodiment:
