[0018] To further illustrate the concept of the present invention, the following will further describe the specific implementation of the present invention with reference to the accompanying drawings:
[0019] A foldable aircraft towing rod comprises a front towing rod 1 and a rear towing rod 2. The rear end of the rear towing rod 2 is fixed with a towing ring 4 by means of a pin hole and a safety pin. At the same time, a handle 9 is installed at the top of the rear section. First, two parallel metal plates are welded as a fixing groove 13. The bottom end of the handle 9 is hinged inside the fixing groove 13. A through hole is opened in the middle of the handle 9, and multiple through holes are opened on the side wall of the fixing groove 13. Then, an auxiliary wheel 6 and a spare socket 14 are installed at the bottom of the rear towing rod 2. The spare socket 14 is a square structure with multiple through holes. A clamping block 7 is welded at the other end of the rear towing rod 2. Multiple through holes are opened on the clamping block 7. An ear piece 11 with through holes is welded at the top of the front section of the rear towing rod 2. Figure 4 shown.
[0020] The rear end of the front traction rod 1 is provided with a slot 8, which corresponds to the block 7, and a through hole is opened on the slot 8, which corresponds to the through hole of the block 7. The moving wheel 5 and the strap 10 are installed in the middle section. The strap 10 is located at the top of the front traction rod 1. A fixed block 12 is welded to the top of the rear section. The middle of the fixed block 12 is slotted to allow the ear piece 11 to be inserted into the fixed block 12, and a through hole is opened on the fixed block 12. The traction joint 3 is set at the front end of the front traction rod 1, as shown in FIG. Figure 3 shown.
[0021] When in use, insert the block 7 of the rear traction rod 2 into the slot 8 of the front traction rod 1, align the through holes of the block 7 and the slot 8, and use a quick release pin or bolt through the through hole to completely fix the block 7 and the slot 8, thereby connecting the rear traction rod 2 and the front traction rod 1. Then rotate the handle 9 to make it stand upright, and align the handle 9 with the through hole of the fixing slot 13, and pass the quick release pin through the through hole to fix the handle 9 in position. Figure 1 The auxiliary wheels 6 and the moving wheels 5 can be used to move the towing rod to the towing position. During the movement, the handle 9 is used to control the moving direction. The towing ring 4 and the towing connector 3 are connected to the towing vehicle and the aircraft respectively to start the towing work.
[0022] After use, all quick release pins are removed to separate the front traction rod 1 and the rear traction rod 2, allowing the handle 9 to rotate freely.
