[0046] Working principle:

[0047] The bracket mechanism realizes the towing function of the projectile 43 through a plurality of brackets 3 installed on the towing chassis 4;

[0048] Since the first bracket 6 and the second bracket 7 are respectively located on both sides of the vertical pole 5 and the first bracket 6 is installed at the top of the vertical pole 5, and the second bracket 7 is installed at the bottom of the vertical pole 5, the first bracket 6 is fixedly connected to the bomb hanging vehicle; the second bracket 7 is used to fix the bracket mechanism, so that the function of the low hanging point is achieved through the above structure. At the same time, a position adjustment mechanism 2 is installed on the second bracket 7, and the position adjustment mechanism 2 is fixedly connected to the bottom surface of the towing chassis 4, so the position adjustment mechanism 2 can adjust the position of the towing chassis 4. In the process of installing the bomb body 43 to the bracket 3, the position adjustment mechanism 2 can be adjusted to facilitate the installation, transportation, disassembly and other processes.

[0049] Through the above structure, the extended, low hanging point bracket is used to expand the function of the bomb hanging vehicle and meet the current low hanging point requirements; the low cost, light and simple structure makes the device practical.

[0050] Among them, in the preferred embodiment of the bracket 3, the bracket 3 is an arc-shaped structure, such as Figure 2 As shown, a protective layer 44 is installed on the inner surface of the bracket 3. Specifically, the protective layer 44 can be a felt pad, so that the elastic body 43 has a shock-absorbing effect.

[0051] Among them, in the preferred embodiment of the bracket 3, there are two brackets 3, and the two brackets 3 are respectively installed on the towing chassis 4 near the two end positions, and a slide groove 8 is provided at the bottom of the bracket 3, and pulley mechanisms are respectively provided near the two ends of the bottom of the slide groove 8;

[0053] Since the bracket 3 is an arc-shaped structure, a pulley mechanism is installed between the two sides of the bottom of the bracket 3 and the towing chassis 4, and a slide groove 8 is opened at the bottom of the bracket 3, and the slide groove 8 is straddled on the two pulley structures, so that the bracket 3 can be rotated within a certain range (depending on the length of the slide groove) through the pulley 10. When assembling the elastic body 43, the bracket 3 can be rotated to reduce the height of one side, so as to facilitate the assembly of the elastic body 43 to the bracket 3.

[0054] Preferably, the pulley structure should maintain the same height to make the structure more stable.

[0055] In a preferred embodiment of the bracket 3 , a drag belt 11 is installed at both ends of the bracket 3 .
