[0032] Further, the elastic member 7 includes a connecting ring and springs connected to both sides of the connecting ring, the connecting rings are respectively sleeved on the second connecting shaft 13 and the second sleeve 14, one side of the two first inclined rods 17 and one side of the two second inclined rods 18 are respectively connected to the connecting rings through springs, and the connecting ring in the elastic member 7 is connected to the spring so that the elastic member 7 has a certain elasticity, wherein when a large recoil is generated during the launching process of the explosive, the first inclined rod 17, the second inclined rod 18 and the connecting ring are deformed, and the spring in the elastic member 7 provides a certain buffer, and the buffering effect is good;

[0033] Furthermore, the two first oblique rods 17 are symmetrically arranged on both sides of the second connecting shaft 13, and the two second oblique rods 18 are symmetrically arranged on both sides of the second sleeve 14;

[0034] Furthermore, there are multiple buffer devices, so as to increase the buffer effect.

[0035] Furthermore, an open groove 8 is provided on the first mounting plate 1 corresponding to the lower side of the gun barrel 3, and long holes 10 are provided on both sides of the open groove 8, and a rotating shaft is installed in the two long holes 10, and a slider 9 is sleeved on the rotating shaft, and the slider 9 is hinged to the bottom end of the first sleeve 4; the rotating shaft can slide in the long holes 10 to adjust the position of the first sleeve 4, so that the angle adjustment of the gun barrel 3 is more extensive.

[0036] For further information, see Figure 3 , the first connecting block 6 is a Y-shaped connecting block, wherein the connection between the first connecting block 6 and the other end of the first connecting shaft 5 is provided with an internal thread, and the other end of the first connecting shaft 5 is provided with an external thread matching the internal thread;

[0039] The complete workflow of the utility model can be: when in use, the second mounting plate 2 is fixed on the ground through the positioning hole by the conical pin 12, and the angle required for throwing is calculated. If the angle of the barrel 3 needs to be adjusted downward, the distance between the other end of the first connecting shaft 5 and the top of the first sleeve 4 is shortened, and the barrel 3 moves downward. If the angle of the barrel 3 needs to be adjusted upward, the distance between the other end of the first connecting shaft 5 and the top of the first sleeve 4 is lengthened, so that the barrel 3 moves upward; if the angle is not enough, the rotating shaft can be slid to the appropriate position of the long hole 10, and the rotating shaft is fixed in the long hole 10 by nuts and gaskets, and then adjusted. After adjustment, the explosive is placed in the barrel 3 for firing. During firing, a huge pressure is generated in the barrel 3 to eject the explosive. At the same time, due to the ejection of the explosive, recoil is generated, which is buffered by the buffer device set between the first mounting plate 1 and the second mounting plate 2, so that the recoil is very small, which greatly reduces the influence of the recoil on the firing angle and makes the landing point more accurate.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
