Description

Winder

The invention relates to a reel that can be turned.

General wearable equipment such as shoes, protective gear, etc. have an adjustment structure to meet the needs of users to adjust to meet the appropriate elasticity and height. For example, the neck guard provides the function of adjusting the height to adjust the support of the neck guard The height of the upper edge of the front edge of the chin allows the user's eyes to look straight ahead.

However, since such a conventional winding device includes a hook-and-loop fastener worn on the wearable device, the hook-and-loop fastener can hold the rope body in position. By pulling the hook-and-loop fastener, the rope body is moved up and down and the hook-and-loop positioning is performed. Adjust the rope body, but the fasteners, such as devil felt, are easily pulled apart and cause the rope to loosen. This will cause the rope body to slide or loosen relative to the fastener because the strength of the fastener to hold the rope is insufficient. If it comes off, the protective gear cannot cover the human body tightly, and there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive reel to solve the above problems.

The main purpose of the present invention is to provide a cord reel, which provides an effective function of retracting and unwinding the cord with a simple structure, and can effectively prevent the rope body from being loosened at will.
