[0020] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with the drawings.

[0021] Referring to Figure 1 , Figure 2 and Figure 3 , the cosmetic powder box accessory provided with the clamping groove comprises an inner cover 1 and a base 2.

[0022] Regarding the inner cover 1

[0023] Preferably, the inner cover 1 is provided with an accommodating cavity with an opening facing upward, so as to accommodate cosmetic powder, a cosmetic brush or a powder puff and the like by using the accommodating cavity. The caliber of the accommodating cavity gradually increases from top to bottom, so as to facilitate the placement of the accommodated objects. The top of the accommodating cavity is provided with a first flange 4 extending in a horizontal direction outward in a ring shape, so as to limit the position of the top of the inner cover 1 by using the first flange 4. The bottom of the accommodating cavity is provided with a first extension extending in a vertical direction downward in a column shape, so as to limit the position of the bottom of the inner cover 1 by using the first extension. Preferably, the first extension is provided with an annular groove 3 with an opening facing outward in a ring shape. The annular groove 3 is connected with the base 2 by clamping. The cross section of the annular groove 3 is preferably in a circular arc shape.

[0024] Regarding the base 2

[0025] The base 2 is annular, comprising a first portion and a second portion. Preferably, the inner diameter of the base 2 gradually decreases first and then remains unchanged from top to bottom, and the portion with gradually decreasing inner diameter is taken as the first portion, and the portion with unchanged inner diameter is taken as the second portion. The inner surface of the first portion is matched with the outer surface of the accommodating cavity, preferably with interference fit. At least three limiting protrusions 7 are equidistantly arranged on the inner surface of the second portion, and the limiting protrusions 7 are clamped into the annular groove 3. Thus, the limiting protrusions 7 are clamped and connected with the inner cover 1. The limiting protrusions 7 are preferably in the shape of spherical caps.

[0026] The top of the first portion is provided with a second flange extending in the horizontal direction. The first flange 4 is pressed on the second flange. Alternatively, no flange is arranged on the first portion, but a certain thickness is provided, so that the first flange 4 can be directly pressed on the side wall of the first portion, and in this case, the top of the side wall of the first portion is taken as the second flange.

[0027] The inner cover and the base can be connected or rotatably connected through a rotating shaft, bending, etc. Preferably, the first flange 4 and the second flange are rotatably connected through a rotating shaft, bending, etc. The center of the connecting point of the rotatable connection is taken as the identification point. The limiting protrusions 7 are staggered with the identification point. Further preferably, the distance between the identification point and the adjacent two limiting protrusions 7 is equal. Thus, the stability of the opening force of the inner cover 1 is maintained when the inner cover 1 is turned over. The limiting protrusions 7 are preferably three, one of which is located opposite the identification point. The width of the annular groove 3 is not less than the outer diameter of the limiting protrusions 7.

[0028] The bottom of the accommodating cavity is provided with anti-skid lines 6. The anti-skid lines 6 are preferably in the shape of fingerprints. Thus, the anti-skid property in the accommodating cavity is improved.

[0029] The first flange 4 is provided with a second extension 5 in the horizontal direction inward on the side opposite to the identification point. Thus, the strength at the first flange 4 is increased by using the second extension 5, and the inner cover 1 is facilitated to be turned over. The upper surface of the second extension is preferably provided with an opening prompt word.
