Specifically, the position of the top protection frame 106 can be moved downward by the first moving component, and the downward movement of the top protection frame 106 can drive the pressure plate 107 inside it and the second moving component arranged thereon to move synchronously. When the top protection frame 106 moves downward to a preset position, the first roller 108 can be rotated, and the first roller 109 can rotate.
