step two: then screwing the compression end shell (202) into the front end shell main body (201), wherein in the screwing process of the compression end shell (202), the conical surface of the head end starts to extrude the second contact elastic piece (302), so that the second contact elastic piece (302) starts to be stressed and elastically bent downwards, and meanwhile, the first contact elastic piece (301) is pressed, so that the first contact elastic piece drives the arched elastic piece (303) to elastically bend until the filler strip (306) compresses the light cone (207);
step three: in the process of continuously screwing and pushing the pressing end shell (202) forwards, the first pressing elastic piece (301) is extruded to slide along the sliding rod (307), so that the spring (308) starts to compress, at the moment, the front end positioning concave plate (304) and the rear end positioning concave plate (305) are attached to the light cone (207) until the side edges are contacted and clamped with the light cone (207), and meanwhile, the positioning protrusions (302 a) are clamped into the positioning clamping grooves, and the pressing rod at the bottom side of the elastic piece button (204) is jacked up to complete limiting fixation;
step four: when the shell is disassembled, the positioning protrusion (302 a) is extruded out of the positioning clamping groove by only pressing the shrapnel button (204), and after the limit is released, the compression end shell (202) is screwed out from one side of the front end shell main body (201).
