The hinge 11 is slidably fitted on the periphery of the shaft 8. A guide rod 13 corresponding to the baffle 9 is installed on the bent part at the upper end of the hook body 1.

[0028] In this embodiment, a hook body 1 is included, and a slot 2 is provided inside the hook body 1;

[0029] Specifically, the inner side of the bent portion of the hook body 1 is provided with an opening 14 that communicates with the slot 2, one end of the hinge 11 is located in the opening 14, the baffle 9 corresponds to the opening 14, and a plate 15 is installed on the lower part of the inner side of the hook body 1.

[0030] Specifically, a slot 18 corresponding to the support rod 17 is provided on the inner side of the upper curved part of the hook body 1, a crossbar 19 is installed between the lower ends of the two support rods 4, and a rectangular slot 20 is provided at the lower end of the hook body 1. Through the provided slot 18, the support rod 17 and the slot 18 are engaged, thereby further reducing the occurrence of the hook body 1 falling off the work point and forming a second layer of insurance.

[0031] Specifically, the lower end of the hook body 1 is equipped with a rod 21 located in the middle of the rectangular groove 20, the lower end of the other support rod 4 is provided with a threaded groove 22, and the lower end of the other support rod 4 is equipped with a nut 23 corresponding to the column 7.

[0032] In this embodiment, two cylindrical bodies 3 are symmetrically installed on the upper end of the hook body 1. Support rods 4 are slidably fitted inside the two cylindrical bodies 3. Stainless steel rings 5 ​​are installed on the upper ends of the two support rods 4. Stop blocks 6 and columns 7 are installed on the lower ends of the two support rods 4 respectively. A shaft 8 is installed in the slot 2.

[0033] Specifically, the diameter of the hole at the upper end of one of the cylinders 3 is smaller than the diameter of the stop block 6, the length of the other support rod 4 is greater than the length of the first support rod 4, and the lower end of the other support rod 4 is slidably fitted into the groove 2. By the fact that the diameter of the hole at the upper end of one of the cylinders 3 is smaller than the diameter of the stop block 6, the stop block 6 can be blocked and limited.

[0034] In this embodiment, a baffle 9 is elastically rotatably fitted on the inner side of the bent portion of the hook body 1. A block 10 is installed on one side of the baffle 9. A hinge 11 is installed at the lower end of the column 7. A U-shaped block 12 that rotatably fits with the block 10 is installed at one end of the hinge 11. The hinge 11 is slidably fitted on the periphery of the shaft 8. A guide rod 13 corresponding to the baffle 9 is installed on the bent portion at the upper end of the hook body 1.

At this time, the stainless steel ring 5 will lift the other support rod 4. Simultaneously, the two support rods 4 slide and engage within the two cylinders 3, causing the other support rod 4 to drive the other end of the hinge 11 to lift synchronously. Thus, the hinge 11 slides and engages with the circumference of the shaft 8 and pulls the baffle 9. At this time, the block 10 and the U-shaped block 12 rotate and engage, which can open the bent part of the hook body 1. At the same time, one end of the hinge 11 is located in the opening 14. After the drone moves the hook body 1 to the vicinity of the working point, it guides... Guided by rod 13, the wire at the work point passes through baffle 9 and enters the curved part inside hook body 1, thereby achieving hooking of hook body 1. Then, the drone is controlled to detach. After the drone detaches, the force of the automatic rotation of the two torsion springs 16 will pull back baffle 9. At this time, baffle 9 pulls back one end of hinge 11, while the other end of hinge 11 slides and engages with the circumference of shaft 8 and pulls back column 7, so that the lower end of another support rod 4 slides and engages in slot 2, thereby closing the curved part of hook body 1. When baffle 9 is closed, the support rod 17 extends into slot 18 and engages with it, forming a second layer of safety. Then, in conjunction with the drone, the power transmission line that needs emergency repair can be quickly repaired.
