Please refer to Figures 8 and 10, the inner surface 71a of each half cover 71 is connected with an abutting member 73, and the abutting member 73 is located inside the corresponding half cover 71; The two abutting members 73 abut the protruding portion P respectively. In this embodiment, the cross-section of each of the abutting members 73 may be approximately in the shape of an inverted U and have a lower bent portion 731. The upper and lower ends of the lower bent portion 731 are respectively There is a closed end 732 and an open end 733. In this way, the two abutting members 73 can cover from the two side covers of the protruding portion P to the protruding portion P, so that the two sides of the protruding portion P can be respectively accommodated in the two downward bending portions 731, and when When the user releases the two-half cover 71, the two-half cover 71 can fall down under the influence of gravity, and naturally the closed end 732 of the bent portion 731 is firmly pressed against the upper end of the protrusion P.

The part of the skirt 734 farther away from the side edge 711 of the half cover 71 can be connected to the inner surface 71a of the half cover 71, and the part of the skirt 734 closer to the side edge 711 of the half cover 71 may choose not to connect the part The inner surface 71a of the half cover 71 enables the half cover 71 to have better elastic deformation ability at the position adjacent to the side edge 711; in this way, when the half cover 71 is to be disassembled, it can be avoided due to the two half cover 71 The part adjacent to the side edge 711 is too hard to be pinched and deformed, which makes it difficult to disassemble the two half covers 71 after the butt joint. In addition, please refer to Fig. 9, the outer surface 71b of each half cover 71 may also have at least one mark 74 to align the at least abutting portion 72, so that the assembler can connect the two half covers 71 in a butt joint state Next, quickly recognize and pinch the position of the butting portion 72 of the two half-cover 71, so that the two half-cover 71 can be separated more quickly.

Please refer to Figures 9-11. Furthermore, each half-cover 71 may also have a thin-walled area 75 that extends longitudinally to the bottom edge of the half-cover 71. The material thickness is thinner than other parts, so that each half cover 71 is easier to elastically deform at the thin-walled area 75, and the two half covers 71 can also be easily disassembled after butt jointing. Wherein, the distance from the thin-walled area 75 to the two side edges 711 is preferably equal, so that when the two half covers 71 are pinched and pressed, an elastic deformation that facilitates separation can occur.

On the other hand, the outer surface 71b of each half cover 71 may have a roughened portion 76 adjacent to the two side edges 711, so that the assembler can hold the roughened portion when the two half covers 71 are butt-joined. At 76, the roughness 76 increases the friction force to improve the firmness of the grip, and reduces the chance of the two half cover 71 slipping off. Wherein, the rough portion 76 can be, for example, a plurality of concave or convex strips.
