[0015] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0016] Example 1

[0017] Attachment Figure 1 —7, comprising a drawstring 1, a fixing ring 2, a ring sleeve 3, a ring hook 4, a quick-release ring 5, a spring 6, and an annular step 7; the fixing ring 2 is cylindrical, with a screw having a diameter smaller than that of the cylinder provided at the center of one end, a circular step formed between the screw and the cylinder, a circular pit provided on the end face of the screw, and a through hole provided at the center of the bottom of the circular pit; the ring hook 4 is in the shape of a two-stage stepped shaft, with an L-shaped hook groove machined at the end with a larger diameter and a threaded inner hole provided at the other end; the ring sleeve 3 is a cylindrical tube with an annular protrusion provided on the outside and an annular step provided at one end of the inner cavity 7; the quick-release ring 5 is a rectangular ring; the pull rope 1 is fixed in the through hole at the center of the circular pit bottom of the fixed ring 2, the screw on the fixed ring 2 is screwed onto the threaded inner hole on the ring hook, the ring sleeve 3 is sleeved on the outside of the ring hook 4, and its annular step 7 faces one end of the ring hook 4. A spring 6 is sleeved on the outside of the ring hook 4 between the inner side of the annular step 7 and the circular step on the fixed ring 2, which tightens the fixed ring 2 and the ring sleeve 3. One end of the L-shaped hook groove of the ring hook 4 is clamped on the outside of the annular step 7 on the ring sleeve 3, and the quick-release ring 5 is hung in the L-shaped hook groove on the ring hook 4.

[0018] The L-shaped hook slot on the ring hook 4 is located within the cylindrical tube on the ring sleeve 3. By manually moving the ring sleeve 3 toward the side of the pull rope 1, the spring 6 is compressed, so that the L-shaped hook slot is exposed through the ring sleeve 3, and the quick-release ring 5 can be separated from the ring hook 4. Under normal use, the spring 6 is tensioned, so that the L-shaped hook slot is located within the cylindrical tube on the ring sleeve 3, and the quick-release ring 5 cannot be separated.

[0019] The beneficial effects of the utility model are: simple structure, not easy to damage, easy to operate and firm structure.

[0020] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
