[0024] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] like Figure 1-4 As shown, this embodiment includes:

[0027] A main hook 1, wherein the main hook 1 is arranged in a "C" shape, and a hanging hole 2 is integrally formed at the right end of the upper plate of the main hook 1;

[0028] Auxiliary hook 3, the auxiliary hook 3 is rotatably mounted on the main hook 1, and the lower end of the auxiliary hook 3 is mounted on the front and rear sides of the main hook 1, and the lower side of the auxiliary hook 3 is integrally formed with anti-slip claw teeth 8;

[0029] A pin rod 5, wherein the pin rod 5 is movably inserted into the main hook 1, and the front and rear side plates of the auxiliary hook 3 are respectively sleeved on the front and rear ends of the pin rod 5;

[0030] The nut 6 is screwed on the front and rear ends of the pin 5 through threads, and the side plate of the auxiliary hook 3 is clamped between the nut 6 and the side wall of the main hook 1;

[0031] A spring 4, wherein the spring 4 is fixedly arranged on the upper side wall of the main hook 1 at one end of the hanging hole 2, and the other end of the spring 4 is extended into the auxiliary hook 3;

[0032] A connecting plate 7, wherein the connecting plate 7 is fixedly arranged on the inner wall of the auxiliary hook 3, and one end of the spring 4 extending in the auxiliary hook 3 is fixedly arranged on the connecting plate 7;

[0033] A limit plate 10, wherein the limit plate 10 is fixedly arranged on the upper side wall of the main hook 1, and a side wall of the auxiliary hook 3 opposite to the hanging hole 2 is movably abutted against the limit plate 10;

[0034] A tubular arm 9, wherein the tubular arm 9 is fixedly arranged at the upper end of the auxiliary hook 3;

[0035] Wing plates 12, wherein the number of the wing plates 12 is two and they are fixedly arranged on the front and rear side walls of the main hook 1 in a front-to-back symmetrical manner;
