[0036] The inner shell 500 is disposed inside the upper shell 100 and the lower shell 200 and is used to fix the driving assembly and the power supply assembly of the corresponding hair trimming device.

[0037] like Figure 6 As shown, the decorative ring 300 includes an inner ring 310 slidably arranged along the outer surface of the inner shell 500, the surface of the inner ring 310 extends outward to form a decorative strip 320, and the decorative strip 320 is circumferentially arranged on the surface of the inner ring 310 in an inclined state, and the edges of the upper and lower sides of the decorative strip 320 match the bottom edge of the upper shell 100 and the top edge of the lower shell 200, and the decorative strip 320 is adapted to the gap when it cooperates with the upper shell 100 and the lower shell 200.

[0038] like Figure 4 , Figure 5 and Figure 6 As shown, the surface of the inner shell 500 is respectively provided with a first limiting structure for limiting the lower end of the decorative ring 300 and a second limiting structure for limiting the upper end of the decorative ring 300.

[0039] The first limiting structure includes a first undercut 510 arranged on the inner shell 500 and the lower edge of the inner ring 310, and the second limiting structure includes a second undercut 520 arranged on the inner shell 500 and a snap 340 arranged on the inner wall of the inner ring 310, and the first undercut 510 and the second undercut 520 are respectively located on both sides of the inner shell 500, and the second undercut 520 is located above the first undercut 510.

[0040] The first inverted buckle 510 and the second inverted buckle 520 both have a downwardly inclined surface, which facilitates the decorative ring to move upward from the bottom of the inner shell body and to achieve a limited fit after respectively passing over the first inverted buckle 510 and the second inverted buckle 520, wherein the lower edge of the inner ring cooperates with the first inverted buckle 510 to form a buckle position, and the second inverted buckle passes over the buckle 340 to form a limited fit therewith, and the two limited fits are relatively arranged, thereby playing a role in positioning the decorative ring.

[0041] One end of the inner ring 310 is provided with a U-shaped notch 330 for avoiding the operating switch 400, and the starting end 321 and the ending end 322 of the decorative strip 320 are respectively located on both sides of the U-shaped notch 330. Moreover, the operating switch is placed at the U-shaped notch, and the decorative strips at both ends just match the cover plate of the operating switch, so that the two form an inclined ring, and the upper and lower sides are both smoothly arranged.

[0042] Preferably, it is a U-shaped notch 330 with the opening facing upward. During assembly, it will not be interfered by the operation switch. Or a circular hole or a hole-shaped structure of other shapes can be adopted. Or the entire inner ring is a disconnected ring structure.

[0043] The inner sides of the starting end 321 and the terminating end 322 of the decorative strip are provided with inclined surfaces 323, which are used for limiting both ends of the cover plate of the button. The cover plate is fixed by the cooperation of the inclined surfaces, which is more convenient during installation and only needs to be slightly pushed in.

By adopting the processing method of closing the two ends, the processing of the upper and lower edges will not have sharp corners, which may cause bumps and sharp corner breakage, affecting the appearance.

[0045] As Figure 7 and Figure 8 shown, the inner edge 3241 at the highest point of the upper edge of the decorative strip 320 is set higher than the outer edge 3242 at the highest point. The lower edge of the upper housing adopts a matching design, so as to have a certain effect of covering the decorative strip, making the cooperation between the two closer and the overall aesthetics higher.

[0046] The inner edge 3241 at the highest point and the outer edge 3242 at the highest point are in an arc transition, reducing the processing difficulty and enabling the upper housing to better fit with the upper edge of the decorative strip.

[0047] As Figure 7 shown, the inner edge 3251 at the lowest point of the lower edge 325 of the decorative strip 320 is set lower than the outer edge 3252 at the lowest point. The lower edge of the lower housing adopts a matching design, so that the lower housing can have a certain effect of covering the decorative strip, making the cooperation between the two closer and the overall aesthetics higher.

[0048] The inner edge at the lowest point and the outer edge at the lowest point are in an arc transition, reducing the processing difficulty and enabling the upper housing to better fit with the upper edge of the decorative strip.

[0049] A positioning groove 350 is provided at the upper end of the inner ring 310, and a positioning block 530 is correspondingly provided on the inner housing 500.
