[0093] Embodiment

[0094] The driven clamping end 2 of the embodiment two is different from that of the embodiment one, and the driving clamping end 1 and the clutch 4 are the same, which will not be described in detail here. Now, the driven clamping end 2 will be mainly described.

[0095] Specifically, as Figures 14 to 16As shown, the passive clamping end 2 includes a passive end mounting rod 25, a clamping mechanism 26, a center positioning ring 27; the passive end mounting rod 25 is cylindrical, the passive end mounting rod 25 is radially provided with a third step, the passive end mounting rod 25 is fixedly connected with the passive clutch 41, or the passive end mounting rod 25 and the passive clutch 41 are an integral structure. The clamping mechanism 26 includes a telescopic ring 261, a clamping ring 262 and an elastic element 222, the telescopic ring 261 is circular and the axial center is a circular hole, the clamping ring 262 is circular and the axial center is a circular hole, and a strip-shaped hole is provided in the radial direction, the number of strip-shaped holes is 2-10, and the number of strip-shaped holes in the embodiment is 6; the outer periphery of the clamping ring 262 is provided with a positive slope, and the inner periphery of the telescopic ring 261 is provided with a reverse slope.

[0096] The working principle of the second embodiment of the present application is that one end of the winding jig 3 is sleeved on the center positioning ring 27, the telescopic ring 261 is stretched forward under the elastic force of the elastic element 222, the reverse slope of the telescopic ring 261 drives the positive slope of the clamping ring 262 to make the clamping ring 262 shrink inward, so as to clamp the winding jig 3.

[0098] 1.

[0100] 3. The other end of the winding jig 3 is also wrapped with the stickers and placed under the clamping ring 121. When the tightening ring 122 moves forward or backward, the reverse slope 1222 drives the head of the clamping ring 121 to shrink inward to clamp the stickers on the outer surface of the winding jig 3 or to stretch outward to loosen the stickers on the outer surface of the winding jig 3 through the matched forward slope 1212. Through the cooperation of the forward slope 1212 of the clamping ring 121 and the reverse slope 1222 of the tightening ring 122, the clamping ring 121 can clamp the stickers of different thickness on the outer surface of the winding jig 3.
