[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. During the actual use of the utility model, by setting multiple groups of rotary display mechanisms, the purpose of simultaneously displaying multiple groups of coils by one device can be achieved. During the display process, open the pressing plate, place one side of the coil to be displayed on the assembly surface, and after covering the pressing plate, the coil can be wound around the mounting roller by rotating the hand crank. During the display process, customers can unfold the corresponding coil for all-round observation according to actual selection, and the remaining coils will vertically drop under the action of gravity, reducing the floor area of the device.

[0013] 2. The pressing plate of the utility model is arranged on the assembly surface through a tension spring. When installing the coil, lift the pressing plate upward to form an installation cavity between the roller body and the pressing plate, place one side of the coil in the installation cavity, and release the pressing plate. The pressing plate rebounds under the action of the elastic potential energy of the tension spring to realize the pressing of the coil, replacing the traditional tape sticking and avoiding the loosening of the coil during winding.
