The unwinding device 2 can be opened by disassembling the second shell 22, and the nose bridge strip coil can be installed and replaced conveniently and quickly.

[0032] Specifically, the mounting plate 11 is provided with a fixed shaft 12, a limiting groove 13 is provided on the fixed shaft 12, a support sleeve 211 is provided in the middle of the first shell 21, and a limiting block 212 which can be engaged with the limiting groove 13 is provided at the center of the support sleeve 211. This structure fixes the first shell 21 to the mounting plate 11. When the nose bridge strip coil is unwinding, the unwinding device 2 will not rotate, but the nose bridge strip coil rotates around the support sleeve 211 to unwind. In this way, there is a certain friction resistance between the nose bridge strip coil and the support sleeve 211 during the unwinding process, which can avoid the situation where the nose bridge strip coil is over-unwinded due to inertia during the unwinding process.

[0033] More specifically, the support sleeve 211 is provided with a connection groove 213, a connection sleeve 221 that can be inserted into the connection is provided in the middle of the second shell 22, and a detachable locking block 23 is provided at the end of the fixed shaft 12, and the locking block 23 can fix the second shell 22, wherein a screw hole 16 is provided at the end of the fixed shaft 12, and the locking block 23 is provided with a threaded portion 231, and the locking block 23 can be connected to the fixed shaft 12 by twisting. The unwinding device 2 can be opened by disassembling the second shell 22, and the nose bridge strip coil is convenient and quick to install and replace. After the second shell 22 is installed, there is a certain gap between the first shell 21 and the second shell 22, which can be used for the nose bridge strip coil to unwind.

[0034] ② Positioning wheel 3, the positioning wheel 3 is provided with a positioning groove a31 for limiting the position of the nose bridge strip, the positioning wheel 3 can be passively rotated, the position of the positioning groove a31 corresponds to the position of the distance between the first shell 21 and the second shell 22, so as to facilitate the stable passage of the nose bridge strip through the positioning wheel 3.
