[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of protection of the utility model.

[0020] As Figs. 1-2 The crane anti-drop hook of the embodiment includes mounting seat 1, first hook 2 at the left side of the bottom of mounting seat 1 and second hook 3 at the right side of the bottom of mounting seat 1, first hook 2 and second hook 3 are symmetrically arranged, and the goods are prevented from falling off. The top end of first hook 2 and the top end of second hook 3 are rotatably installed at the bottom of mounting seat 1 through torsional springs and shafts respectively, the hook of first hook 2 and the hook of second hook 3 include hook handle 4, hook bend 5 and hook tip 6, the hook tip 6 on first hook 2 and the hook tip 6 on second hook 3 form X structure by interlacing each other. It is convenient and fast to connect with goods.

[0021] Further, the first hook 2 is located at the front side of the second hook 3.

[0022] Further, the top end of mounting seat 1 is fixedly connected with the cable on the crane.

[0023] Working principle: when the crane is working, the lifting cable drives the mounting seat 1 to descend, the workers hold the mounting seat 1, and the hook tips on the first hook 2 and the second hook 3 are astride on the hanging rod on the goods in the interlaced position, when the mounting seat continues to descend with the lifting cable, due to the gravity of the first hook 2, the second hook 3 and the mounting seat 1, the hanging rod on the goods can extrude the hook tips of the first hook 2 and the second hook 3 to the two sides, the hook tips 6 of the first hook 2 and the second hook 3 are separated to the two sides, the hanging rod on the goods passes through the hook tips 6 to the upper of the hook tips 6, under the action of the torsional spring, the first hook 2 and the second hook 3 reset, and the suspension on the goods is realized. When the goods is swinging, the hook tips 6 on the first hook 2 and the second hook 3 can block the hanging rod on the goods. When the goods needs to be unloaded, the lifting cable drives the mounting seat 1 to descend, the hanging rod on the goods is located behind the hook handle position, the first hook 2 and the second hook 3 are manually opened to the two sides, the lifting cable drives the mounting seat 1 to ascend, and the first hook 2 and the second hook 3 separate from the hanging rod on the goods with the mounting seat 1 ascending.
