[0002] A tethered drone is a type of drone that can fly continuously and stay in the air. Its working principle is to tether the drone to a fixed position by using ropes, balloons, parachutes, etc., to achieve long-term hovering and observation. Compared with traditional drones, tethered drones have the advantages of low energy consumption, long flight time and low cost. At present, tethered drones are mainly divided into two types: balloon tethered and rope tethered.

[0003] As drone technology is changing with each passing day, the fire-fighting field has begun to use drones for related operations. The use of drones has also provided a solution to high-rise building fires. In the use of high-altitude fire-fighting tethered drones, it is usually necessary to connect a load-bearing sling to suspend fire-fighting tools and materials, etc. Different load-bearing slings need to be replaced for different application scenarios. In the prior art, the load-bearing sling is generally fixed to the frame of the drone by bolts. This bolt fixing, assembly and disassembly and replacement of the sling are very troublesome and time-consuming, which affects the application efficiency. Therefore, the utility model proposes a load-bearing joint for high-altitude fire-fighting tethered drones to solve the problems existing in the prior art. Utility Model Content
