[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, the ceremonial gun of the present invention comprises a buttstock 1, a barrel assembly, a bolt assembly, a casing 7, a bayonet assembly, a firing mechanism, and a magazine 15. The barrel assembly comprises a barrel 10, a buttstock hoop 2, a cover tube 5, and a cover 6. The casing 7 is arranged at the rear end of the barrel 10 and is connected to the barrel. The casing is a square frame structure, and the bolt assembly is arranged in the casing. A groove is provided on the upper end surface of the front part of the buttstock 1, and a through groove is provided in the middle part of the buttstock to longitudinally penetrate the buttstock; the rear part of the barrel is embedded in the groove, the front part of the barrel 10 extends out of the front part of the buttstock, and a bayonet assembly is arranged at the front end of the barrel. The bayonet is unfolded in wartime and folded under the barrel and the buttstock at ordinary times. The casing 7 and the bolt assembly are arranged on the upper part of the through groove of the buttstock, and the firing mechanism and the magazine 15 are installed on the lower part of the through groove. The positions of the magazine and the bolt assembly correspond to each other, and the firing mechanism is installed at the rear part of the magazine. The length of the ceremonial gun when the bayonet is deployed is 0.5m to 1.8m, with the preferred length being 1340mm.

[0045] The buttstock 1 is made of wood material, and is in the shape of a long strip structure that is narrow in front and wide in the back, with a downwardly bent arc in the middle; the buttstock is 750mm long, and the thickness of the rear end of the buttstock is 41mm. The buttstock is longer and thicker than the buttstock of the original Type 56 semi-automatic rifle, which is conducive to hand holding or shoulder fixation when holding the gun. A shallow groove is opened on the lower end surface of the front part of the buttstock as a bayonet groove. The cross-section of the bayonet groove is U-shaped, with a length of 165mm and a width of 6.5mm. When the bayonet is folded, the bayonet tip and part of the blade are stored in the groove. The bayonet groove is longer and wider than the original gun to better adapt to the new extended bayonet.

[0046] like Figure 4 As shown, the butt hoop 2 in the barrel assembly is sleeved on the middle of the barrel and is used to fix the barrel to the front end of the butt. A round hole is opened on the upper part of the butt hoop 2, and the diameter of the round hole matches the diameter of the barrel. A trapezoidal incision is opened on the lower part of the butt hoop, and the bottom edge width of the incision is 6.5mm. The incision is used to store the blade when the bayonet is folded. A protective cover tube 5 and a protective cover 6 are set on the upper part of the barrel. The protective cover tube is a metal tubular structure. The rear part of the protective cover tube is connected to a wooden protective cover 6. The protective cover is a hollow semi-cylinder covering the barrel. A front sight 11 is set above the front end of the barrel 10, and a protective cover tube 5, a protective cover 6 and a sight plate 12 are sequentially set above the middle part, and a sight is installed on the sight plate.

[0047] The bolt assembly includes a bolt body 4 and a bolt core 17. The bolt body 4 is a columnar structure, and the bolt core 17 is movably arranged below the bolt body 4. A protruding portion is arranged on the side of the front end of the bolt body, which is used to pull the bolt assembly to move. A recoil spring and a rod 16 are installed in the bolt body, and extend backward out of the bolt body, which is used to reset the pulled bolt assembly. A shell extractor and a shell extractor spring are installed in the bolt core. The bolt assembly is installed in the receiver 7, and a receiver cover 3 is installed above the rear end of the receiver. The receiver cover is a semi-cylindrical structure, and the receiver cover cooperates with the receiver 7. Pull the bolt body 4 backward, and the bolt assembly retreats to the rear of the receiver, and is now in a ready-to-fire state.

[0048] The firing mechanism includes a trigger 14, a firing bracket 13, a trigger spring, a firing spring, a safety and a hammer, and the firing bracket 13 is fixed to the lower rear of the receiver 7 through a firing bracket buckle. The trigger 14 and the safety are located at the lower part of the firing bracket 13, and the hammer, the trigger spring and the firing spring are located above the firing bracket.

[0049] The bayonet assembly includes a bayonet handle 9, a bayonet 8 and a bayonet shaft. The shape of the bayonet is changed from the original three-edged bayonet of the gun to a flat bayonet with a single edge. The bayonet is 10 mm to 500 mm long, preferably 380 mm. The end of the bayonet 8 is connected to the bayonet handle 9, and the bayonet handle is connected to the front of the gun barrel 10 through the bayonet shaft. When the bayonet is deployed, the ring on the bayonet handle fixes the bayonet on the gun barrel; the bayonet handle is pulled toward the front of the gun to release the lock, and the bayonet is bent downward and closed in the bayonet groove.
