Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not limited to the present invention.

As shown in fig. 1, the present embodiment provides a retractor including a retracting strap; the retractor belt is provided with a combination part, and the combination part is used for combining two ends of the retractor belt together so as to be suitable for the retractor belt to form a curved traction part.

The combination part comprises a concave part and a convex part, wherein the concave part is arranged at one end of the retracting belt, the convex part is arranged at the other end of the retracting belt, and the concave part and the convex part are matched with each other so as to be suitable for combining the two ends of the retracting belt together through buckling of the concave part and the convex part.

As shown in fig. 2 and 3, the combining part is a ring buckle which can be arranged on the retracting belt; the two ends of the retracting belt are accommodated in the ring buckles, so that the middle of the retracting belt is suitable for forming a curved traction part.

The actual arrangement of the combining portion of the retracting belt provided by this embodiment can be adjusted as required, for example, the dimensions of the concave portion and the convex portion are reduced, or the positions of the concave portion and the convex portion are set at appropriate positions on the retracting belt, and can be set at a position away from one end of the retracting belt.

As shown in fig. 4, the ring buckle is provided with an open slot for clamping the retracting belt; the opening side of the open slot is larger than the bottom of the open slot so as to be suitable for the open slot to form a V shape;

a hole for accommodating the retracting belt is formed in the position, located in the open slot, of the ring buckle, so that the ring buckle can slide along the retracting belt;
