[0036] Such as Figures 1 to 4As shown in the figure, the utility model provides an auxiliary device for loading a mortar, which comprises a flared mouth part 1, a barrel part 2 and a fastener 3. The flared mouth part 1 includes a front section and a rear section. The front section is flared, and the rear section is a hollow cylinder. An outer protrusion 102 is arranged around the bottom end of the rear section. The barrel part 2 is a hollow cylinder, and two side protrusions 201 are arranged on the barrel part 2. The flared mouth part 1 is sleeved on the barrel part 2. The fastener 3 is installed outside the two side protrusions 201 of the barrel part 2 and is used to fix the outer protrusion 102 and the two side protrusions 201 together.

[0037] Before loading the mortar, according to the technical solution of the utility model, the flared mouth part 1 is sleeved on the barrel part 2, so that the outer protrusion 102 at the bottom end of the rear section of the flared mouth part 1 contacts the two side protrusions 201 of the barrel part 2. At this time, the fastener 3 is installed outside the two side protrusions 201 of the barrel part 2 to fix the outer protrusion 102 and the two side protrusions 201 together, that is, to fix the flared mouth part 1 and the barrel part 2 together, playing a role of limiting. The structure is compact, can prevent slipping, and is convenient to further load the projectile in place.

[0038] As Figure 1 and Figure 2 shown, an inner protrusion 101 is also arranged at the connection between the front section and the rear section of the flared mouth part 1, and the thickness of the inner protrusion 101 does not exceed the thickness of the barrel part 2. When using the device, the inner protrusion 101 contacts the top end of the barrel part 2, which can ensure that the top end of the barrel part 2 just gets stuck at the connection between the front section and the rear section of the flared mouth part 1, and the flared mouth part 1 will not move further towards the direction close to the bottom end of the barrel part 2.

[0039] The thickness of the outer protrusion 102 at the bottom end of the flared mouth part 1 is the same as the thickness of the two side protrusions 201 of the barrel part 2. The length of the rear section of the flared mouth part 1 is the same as the distance from the top end of the barrel part 2 to the two side protrusions 201. The two side protrusions 201 of the barrel part 2 are symmetrically arranged.

[0040] As Figure 4 shown, the fastener 3 includes a first claw 301, a second claw 302 and a bolt 304. The inner edges of the first claw 301 and the second claw 302 are both arc-shaped. One end of the first claw 301 and the second claw 302 is connected by a first pin 305, and the other end of the first claw 301 and the second claw 302 is connected by a bolt 304 and a second pin 306. Specifically, one end of the first claw 301 and the second claw 302 is rotatably connected by a first pin 305. The second pin 306 penetrates through the other end of the second claw 302, and the second pin 306 penetrates through the head of the bolt 304. A rotating section is arranged on the head of the bolt 304, that is, the second claw 302 and the rotating section of the bolt 304 are rotatably connected by the second pin 306.

[0041] Fixing grooves 303 are provided on the inner sides of the first jaw 301 and the second jaw 302. The depth of the fixing groove 303 is the same as the thickness of the outer protrusion 102 and the thicknesses of the two side protrusions 201. The width of the fixing groove 303 is the same as the sum of the widths of the outer protrusion 102 and the two side protrusions 201. The outer protrusion 102 and the two side protrusions 201 can be jointly fixed in the fixing groove 303 to prevent slipping.

[0042] The materials of the flared portion 1 and the barrel portion 2 are both aluminum alloy. The material of the fastener 3 is aluminum alloy. Considering that during firing, since the gas is ejected upward and forward, the impact on the surroundings is small, so the requirement can be met by using aluminum alloy material.

[0043] Working process:

[0044] This device is made of aluminum alloy material to achieve the purpose of light weight, and includes a flared portion 1, a barrel portion 2 and a fastener 3. According to the specific outer dimensions of the mortar, the front section of the flared portion 1 is sleeved into the mortar mouth (i.e., the top end of the barrel portion 2). The front section of the flared portion 1 is set in a flared shape, which is convenient for loading. When loading, only the bottom of the projectile needs to be placed into the flared portion 1 of this device, and the projectile is straightened. The projectile can be smoothly loaded in place by using the gravity of the projectile.

[0045] At the same time, considering that during firing, since the gas is ejected upward and forward, the impact on the surroundings is small, so the requirement can be met by using aluminum alloy material.

[0046] Combined with the outer protrusion 102 at the bottom end of the flared portion 1 and the two side protrusions 201 of the barrel portion 2, the flared portion 1 and the barrel portion 2 are fixed together by the fastener 3 to prevent slipping.

[0047] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
