[0019] The technical solutions of the present application will be further described and illustrated below with reference to the drawings and embodiments.

[0020] In this embodiment, as Figures 1-3As shown in the figure, it is a special grounding terminal for a drone, including a telescopic hook 1. The lower end of the telescopic hook 1 is connected to a folding baffle 2. The upper end side of the folding baffle 2 is fixedly connected with a wire gripper 3. The wire gripper 3 includes an upper fixed seat 4. The lower end of the upper fixed seat 4 is hinged to a lower movable seat 5. Semi-circular clamping grooves 6 are provided on the lower surface of the upper fixed seat 4 and the upper surface of the lower movable seat 5. When the upper fixed seat 4 and the lower movable seat 5 are closed, the two clamping grooves 6 form a circle. A limiting rod 7 is hinged on the lower movable seat 5. A limiting groove 8 is provided on the limiting rod 7. A limiting pin 9 that is clamped with the limiting groove 8 is provided on the upper fixed seat 4. When the limiting pin 9 is arranged in the limiting groove 8, the lower movable seat 5 is in an open state. A torsion spring is provided at the hinge shaft of the upper fixed seat 4 and the lower movable seat 5.

[0021] Specifically, the folding baffle 2 includes an L-shaped rod 201 fixed to the side of the wire gripper 3. The upper end of the horizontal section of the inverted L-shaped rod 201 is connected to the telescopic hook 1 by a bolt. The lower end of the vertical section of the L-shaped rod 201 is hinged to a folding rod 202. A hanging ring 203 is provided at the free end of the folding rod 202.

[0022] Specifically, the telescopic hook 1 includes a seat body 101 connected to the upper end of the horizontal section of the L-shaped rod 201. A hook body 102 is telescopically connected in the seat body 101. The telescopic mode of the telescopic hook 1 is the same as that of the antenna.

[0023] Specifically, a connection point 204 for the grounding wire is provided at the upper end of the folding baffle 2.

[0024] During operation, the operator assembles the telescopically separable telescopic hook 1, folding baffle 2, and wire gripper 3. Connect the lower end of the telescopic hook 1 to the upper end of the horizontal section of the L-shaped rod 201 in the folding baffle 2 with a bolt. At the same time, connect the side of the wire gripper 3 to the side of the vertical section of the L-shaped rod 201 with a bolt. After the connection is completed, rotate the lower folding rod 202 by 180° so that it is arranged in the same direction as the vertical section of the L-shaped rod 201. Fix one end of the external soft grounding copper wire to the connection point 204 at the upper end of the folding baffle 2, and connect the other end to the ground clamp of the external grounding wire. At the same time, rotate the lower movable seat 5 counterclockwise so that the limiting groove 8 on the limiting rod 7 is clamped on the limiting pin 9, so that an open and closed state is formed between the upper fixed seat 4 and the lower movable seat 5. The drone is fixed at the upper end of the telescopic hook 1. Place the power cord wire connected to the drone, etc. in the clamping groove 6. Due to the extrusion effect, the limiting rod 7 is separated from the limiting pin 9. At the same time, due to the resetting effect of the torsion spring at the hinge of the upper fixed seat 4 and the lower movable seat 5, the lower movable seat 5 is reset clockwise to clamp and bite the power cord wire. After fixing, the operation can be carried out.

[0025] The present utility model is not limited to the above embodiments. Based on the technical solutions disclosed by the present utility model, those skilled in the art can make some substitutions and deformations to some of the technical features without creative labor according to the disclosed technical content, and these substitutions and deformations are all within the protection scope of the present utility model.
