The protective inner cover 5 is fitted with the receiving groove 3, and the protective inner cover 5 is snap-fitted and fixedly matched with the snap assembly.
[0029] The cover body 1 and the base plate 2 can be used as the first layer of protection structure of the silencer, and the receiving groove 3 and the protective inner cover 5 can be used as the second layer of protection structure. The double-layer protection greatly improves the protection capability of the silencer. The cover body 1 and the base plate 2 can be conveniently and quickly disassembled and installed through the snap-on assembly, making the process of removing and placing the silencer convenient and quick, thereby improving the efficiency of transporting the silencer.
[0030] The snap assembly includes a pair of spring grooves 6 opened in the cover body 1, and a snap block 7 slidably connected in the spring groove 6. One end of the snap block 7 extends into the inner liner snap groove 4. A pair of inner grooves 13 are opened on the surface of the protective inner cover 5. One end of the snap block 7 is snap-fitted with the inner groove 13, and a compressed spring 8 is fixed between the other end of the snap block 7 and the bottom of the spring groove 6.
[0031] With the above structure, the buckle block 7 can be pushed by the compression spring 8 to buckle with the surface of the protective inner cover 5, thereby realizing the rapid fixation of the protective inner cover 5, and further completing the combined fixation between the cover body 1 and the base plate 2, thereby improving the overall efficiency.
[0032] A rope hole 9 is provided in the cover body 1 , one end of the rope hole 9 is connected to the surface of the cover body 1 , and the other end of the rope hole 9 is two branch channels respectively connected to the bottom of the corresponding spring groove 6 .
[0033] With the above structure, the drawstring hole 9 can be opened to communicate with the bottom of the spring groove 6, so as to facilitate the subsequent pulling of the buckle block 7 by controlling the drawstring 10.
[0034] A control pull rope 10 is sleeved in the pull rope hole 9 , one end of the control pull rope 10 is fixedly connected to a pull ring 12 , and the other end of the control pull rope 10 is divided into two thin ropes which are respectively fixedly connected to the other end of the buckle block 7 .
[0035] With the above structure, the pull rope 10 can be pulled by the pull ring 12, and then the buckle block 7 can be pulled by the pull rope 10, so that the buckle block 7 retracts into the spring groove 6, thereby disengaging from the buckle fit with the surface of the protective inner cover 5, facilitating the rapid disassembly of the protective inner cover 5, and further completing the rapid disassembly between the cover body 1 and the base plate 2, thereby improving the overall efficiency.
