The rotation groove 104 can limit the first tongue in the up and down directions to prevent the second cover body 2 from falling off the first cover body 1. At the same time, the second connection buckle position 203 cooperates with the first connection buckle position 105 to prevent the first tongue from rotating in the direction of the positioning groove 103, so as to prevent the first tongue from leaving the rotation groove 104. Therefore, the cooperation between the first fixing buckle position 102 and the second fixing buckle position 202, and the cooperation between the first connection buckle position 105 and the second connection buckle position 203 can realize the fixing of the connection between the first cover body 1 and the second cover body 2 in the circumferential direction and the up and down direction, so as to prevent loosening during use.

[0130] In one embodiment, Figure 6 and Fig.16 The first connection buckle position 105 is an elastic hook, and the second connection buckle position 203 is a second protruding tongue arranged on the inner side of the second mounting surface 201.

[0131] In this embodiment, when connecting the first cover body 1 and the second cover body 2, first buckle the second cover body 2 onto the first cover body 1, so that the first tongue is embedded in the positioning groove 103, and then rotate the first cover body 1 or the second cover body 2 so that the first tongue enters the rotation groove 104. The rotation groove 104 can limit the first tongue in the up and down directions to prevent the second cover body 2 from falling off the first cover body 1. At the same time, the elastic hook hooks the second tongue to prevent the first tongue from rotating toward the positioning groove 103, so as to prevent the first tongue from leaving the rotation groove 104. Therefore, the cooperation between the first fixing buckle position 102 and the second fixing buckle position 202, and the cooperation between the first connecting buckle position 105 and the second connecting buckle position 203 can realize the fixing of the connection between the first cover body 1 and the second cover body 2 in the circumferential direction and the up and down direction, so as to prevent loosening during use.

[0133] In this embodiment, when connecting the first cover body 1 and the second cover body 2, the second cover body 2 is first buckled on the first cover body 1 so that the first tongue is embedded in the positioning groove 103, and then the first cover body 1 or the second cover body 2 is rotated to make the first tongue enter the rotation groove 104. The rotation groove 104 can limit the up and down directions of the first tongue to prevent the second cover body 2 from falling from the first cover body 1. At the same time, the seventh connecting portion 1053 is elastically deformed in the direction away from the first mounting surface 101 so that the second tongue passes over the seventh connecting portion 1053. After passing over the seventh connecting portion 1053, the seventh connecting portion 1053 returns to its original position to hook the second tongue, preventing the first tongue from rotating toward the positioning groove 103, thereby preventing the first tongue from leaving the rotation groove 104.

[0134] Specifically in one embodiment, Figure 4 As shown, along the circumferential direction, the first connecting buckle position 105 is located between the two first fixing buckle positions 102 , and the sixth connecting portion 1052 of the first connecting buckle position 105 extends toward the first connecting portion 1021 of one of the first connecting buckle positions 105 .

[0136] In this embodiment, a guiding bevel 10531 is provided at one end of the seventh connecting portion 1053 facing the first mounting surface 101. When the second cover body 2 is rotated, when the second protruding tongue contacts the guiding bevel 10531, it will slide relative to the guiding bevel 10531, causing the seventh connecting portion 1053 to undergo elastic deformation. After the second protruding tongue passes over the seventh connecting portion 1053, the seventh connecting portion 1053 returns to its original position and hooks the second protruding tongue, thereby preventing the first protruding tongue from rotating toward the positioning groove 103.

[0137] In one embodiment, a side of the seventh connection portion 1053 facing the fifth connection portion 1051 is a rotation-stopping surface 10532, an angle α is included between a vertical plane 3 perpendicular to the first mounting surface 101 and the rotation-stopping surface 10532, and a friction coefficient between the second protrusion and the rotation-stopping surface 10532 is μ, μ>tanα.

[0138] In this embodiment, the angle between the vertical plane 3 perpendicular to the first mounting surface 101 and the anti-rotation surface 10532 is α, the friction coefficient between the second protruding tongue and the anti-rotation surface 10532 is μ, μ>tanα, and when the second cover body 2 is subjected to a rotational force, the second protruding tongue cannot separate from the elastic hook.

[0139] Specifically, assuming that the gyroscopic force is F, the positive pressure of the second tongue on the anti-rotation surface 10532 is N, the resultant force of F and N is F1, F1 = N*tanα, the friction resistance between the second tongue and the anti-rotation surface 10532 is f, and the friction coefficient is μ. To ensure that it cannot be dislodged, it is necessary to satisfy f>F1, then N*μ>N*tanα, so the result is μ>tanα.
