By providing the tightening grooves 9 on the lower side of the upper clamping jaw 301 and the upper side of the lower clamping jaw 302, the clamping force can be enhanced to ensure that the clamped object is firm and stable.

[0031] The tightening groove 9 is an arc-shaped structure, which increases the contact area between the lower side of the clamping jaw 301 and the lower clamping jaw 302 and the wire, and can provide a greater clamping force, making the clamping more firm and reliable, ensuring that the clamped object is not easy to fall off.

[0032] A rubber pad 10 is provided in the tightening groove 9, which can play a shock-absorbing and buffering role, reduce the impact force during the clamping process, and protect the clamped object from damage. On the other hand, the rubber material has a certain friction force, which can increase the clamping force and prevent the clamped object from sliding or shifting.

[0033] The lower clamping jaw 302 is provided with a detection sensor 11, which can monitor the status and position of the lower clamping jaw 302 in real time and provide accurate data feedback. Through the detection sensor 11, abnormal conditions in the clamping process can be discovered in time, thereby improving operational safety and avoiding accidents.

[0034] The locking assembly 6 includes a ratchet baffle 601 and a limiting rod 602. The ratchet baffle 601 is rotatably connected to the upper clamping jaw 301.

[0038] A first pulley 14 is provided at the upper end of the main hook 1, and the first pulley 14 is in contact with the support plate 4. The contact between the first pulley 14 and the support plate 4 can reduce friction, so that the main hook 1 moves more smoothly and reduces energy loss. In addition, the setting of the first pulley 14 can increase the supporting area of ​​the support plate 4 for the main hook 1, thereby improving the stability and reliability of the structure.

[0039] The utility model is a gravity self-locking mechanical structure. The drone grips the lifting hook 5 of the device to take off. Under the action of its own gravity, the upper jaw 301 and the lower jaw 302 of the device are in an open and closed state, which is convenient for hanging the wire. The drone slowly lands. When the upper jaw 301 of the device approaches the wire, the lifting hook 5 sinks, and the main hook 1 in contact with it sinks due to its own gravity, while the lower jaw 302 connected to it rises until it touches the wire. The drone can release the lifting hook 5 of the device. When the lifting hook 5 sinks, the ratchet baffle 601 in contact with it will also sink due to its own gravity. Until it contacts with the lower clamping jaw 302, then at this time, the upper clamping jaw 301, the lower clamping jaw 302 and the ratchet baffle 601 form a closed loop with the wire, and the rubber pad 10 in the tightening groove 9 of the upper clamping jaw 301 and the lower clamping jaw 302 can play a shock-absorbing and buffering role, reduce the impact force during the clamping process, and protect the clamped object from damage. On the other hand, the rubber material has a certain friction force, which can increase the clamping force and prevent the clamped object from sliding or shifting; the safety rope 2 is subjected to downward force, so the device will be pulled tighter and tighter, and the upper clamping jaw 301 and the lower clamping jaw 302 will tightly hold the wire; through the design of the ratchet baffle 601 and the limit rod 602, the reliable locking of the device can be achieved, so that the device will not be disengaged, thereby ensuring safety; the detection sensor 11 can monitor the state and position of the lower clamping jaw 302 in real time, provide accurate data feedback, and through the detection sensor 11, abnormal conditions in the clamping process can be discovered in time, improving operational safety and avoiding accidents;

[0040] When the device needs to be dismantled, the drone is operated to grab the lifting hook 5, and the lifting hook 5 will drive the connecting rod assembly 8 upward to release the ratchet baffle 601, and the ratchet baffle 601 and the upper clamping jaw 301 will also move upward, so that the upper clamping jaw 301 and the lower clamping jaw 302 are opened for release and removal.

[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
