[0002] The exhaust noise of the internal combustion engine is discharged into the atmosphere after being reduced by the muffler, so that the exhaust noise of the internal combustion engine meets the specified requirements. During the operation of the internal combustion engine, carbon soot is generated due to the burning fuel. When it works normally, the slight carbon soot generated can be discharged together with the exhaust gas.

A positioning block 312 is fixedly connected to one side of the end cover 2, a snap-in groove 313 is provided on the outer side of the positioning block 312, a magnet 314 is fixedly connected to the inner wall of the snap-in groove 313, a positioning hole 315 is provided on the outer wall of the main body 1, a fixing frame 316 is fixedly connected to the outer wall of the main body 1, a snap-in rod 317 is movably connected inside the fixing frame 316, the outer end of the snap-in rod 317 is fixedly connected to a limiting block 318, a spring 319 is fixedly connected to the inner side of the limiting block 318, a positioning strip 3110 is fixedly connected to the outer wall of the snap-in rod 317, a movable hole 3111 is provided inside the fixing frame 316, and a limiting groove 3112 is provided on the outer side of the fixing frame 316.

[0033] In this embodiment, the clamping rod 317 is movably penetrated and clamped with the main body 1 and the clamping groove 313, and the spring 319 is fixedly connected to the fixing frame 316 at one end away from the limiting block 318. Through the cooperation of the positioning hole 315, the positioning block 312, the clamping groove 313, the fixing frame 316, the clamping rod 317, the limiting block 318, the spring 319, the positioning strip 3110, the movable hole 3111, and the limiting groove 3112, it is convenient to manually disassemble the end cover 2, thereby facilitating manual cleaning of the inside of the main body 1, and because the front muffler 4 is threadedly connected to the end cover 2, it is convenient to manually disassemble the front muffler 4, and then the front muffler 4 can be further cleaned.

[0034] Furthermore, the positioning bar 3110 is slidably connected in the movable hole 3111 , and the positioning bar 3110 is adapted to the limiting groove 3112 .

[0035] Furthermore, the clamping rod 317 is made of iron material, and the magnet 314 can achieve better clamping effect with the clamping groove 313 under the action of suction, so that the connection relationship between the positioning block 312 and the positioning hole 315 can be more stable, thereby making the end cover 2 more stable during use.

[0036] Furthermore, there are two positioning blocks 312 symmetrically distributed at the lower part of the end cover 2 .

[0037] Furthermore, the size of the sealing ring 311 is slightly larger than the inner diameter of the main body 1, and the sealing ring 311 is made of soft sealing material.

[0038] When the end cover 2 needs to be disassembled, the clamping rod 317 is first pulled outward manually, so that the clamping rod 317 can be moved outward and separated from the clamping groove 313, and when the clamping rod 317 moves outward, the positioning bar 3110 fixedly connected to the outer wall of the clamping rod 317 can be moved outward synchronously. When the positioning bar 3110 moves outward and separates from the movable hole 3111, the clamping rod 317 is manually rotated to drive the positioning bar 3110 to rotate, and the positioning bar 3110 is matched with the limiting groove 3112, and the spring is used to lock the clamping rod 317. Under the action of elastic force, 319 can make the positioning strip 3110 engage with the limiting groove 3112, so that the engaging rod 317 can stay at a position away from the engaging groove 313, freeing up the hands of the workers, making it easier for the workers to disassemble and assemble the end cover 2. Then, the end cover 2 can be taken out upwards manually, making it easier for the workers to clean the inside of the main body 1. Moreover, since the front muffler pipe 4 is threadedly connected to the end cover 2, it is easier for the workers to further disassemble the front muffler pipe 4 and clean the front muffler pipe 4.
