[0027] See also Figure 2 In order to ensure that the blade 84 rotates normally and that the angle of the blade 84 can be adjusted, a covering plate 3 is fixedly connected to the upper part of the inner wall of the inner cavity of the shell 2, and the covering plate 3 is ring-shaped. A connecting shell 4 is fixedly connected to the inner side of the covering plate 3. A trimming device 8 is provided in the middle of the inner cavity of the connecting shell 4, and the lower part of the trimming device 8 is movably connected to the angle adjustment device 7, and the stability of the connecting shell 4 is effectively guaranteed. In order to completely shave the beard on the face and lips of the user, a floating device is provided on the bottom end surface of the inner cavity of the connecting shell 4, and a net cover 5 is fixedly connected to the upper part of the floating device. The net cover 5 can protect the skin and ensure that the trimmed hair will not fly.

[0028] See also Figure 2 In order to adjust the angle of the cutter head and adjust it in the front, back and left and right directions at the same time, an angle adjustment device 7 is composed of a limiting groove 71, a connecting column 72, a sphere 73, a spherical groove 74, a connecting head 75 and a rotating shaft 76. A rotating shaft 76 is fixedly connected to the upper end surface of the driving shaft of the driving motor 10, and a connecting head 75 is fixedly connected to the upper end surface of the rotating shaft 76, and the cross-sectional area of ​​the connecting head 75 is larger than the rotating shaft 76. A spherical groove 74 is fixedly opened in the middle of the upper end surface of the connecting head 75, and a sphere 73 is installed in the inner cavity of the spherical groove 74. A connecting column 72 is fixedly connected to the upper end surface of the sphere 73, and a limiting groove 71 is opened in the middle of the upper end surface of the connecting column 72, and the limiting groove 71 matches the lower part of the trimming device 8.

[0029] See also Figure 2In order to ensure that the driving motor 10 drives the connecting head 75 to rotate and prevent the ball 73 from sliding in the inner cavity of the spherical groove 74, causing the ball 73 to be in a static state as a whole, a guide block is fixedly connected to the bottom of the outer wall of the spherical groove 74, and guide grooves are evenly opened on the inner wall of the inner cavity of the spherical groove 74. The guide grooves are in a cross-shaped structure, and the cross connection of the guide grooves is connected to ensure the normal passage of the guide block, thereby ensuring that the ball can rotate normally with the connecting head 74.

[0030] See also Figure 2 and Figure 3 In order to ensure the normal rotation of the trimming device 8 and the stability of the connecting shell 4, the trimming device 8 is composed of a bearing 81, a connecting shaft 82, a rotating rod 83 and a blade 84. A bearing 81 is provided through the bottom end surface of the inner cavity of the connecting shell 4, and a connecting shaft 82 is fixedly connected to the inner ring of the bearing 81. The cross-section of the connecting shaft 82 is the same as the cross-section of the limiting groove 71, and the connecting shaft 82 matches the limiting groove 71. The lower end of the connecting shaft 82 is installed in the inner cavity of the limiting groove 71, and the upper end surface of the connecting shaft 82 is evenly fixedly connected with a rotating rod 83, and six groups of rotating rods 83 are provided. Blades 84 are fixedly connected to the upper end surfaces of the six groups of rotating rods 83. The rotation of multiple groups of blades 84 effectively improves the trimming speed.

[0031] See also Figure 4 In order to ensure that the roots of the beard can be shaved clean by pressing the mesh cover 5, a floating device is formed by the spring clip 11 and the return spring 12. Four groups of spring clips 11 with the same structure are arranged on the outer circle of the bottom end surface of the inner cavity of the connecting shell 4, and the four groups of spring clips 11 are arranged in a ring array on the bottom end surface of the inner cavity of the connecting shell 4, and the spring clips 11 are inclined toward the center of the inner cavity of the connecting shell 4. The lower end surface of the spring clip 11 close to the outer circle of the connecting shell 4 is fixedly connected with the return spring 12, and the end of the return spring 11 is fixedly connected to the bottom end surface of the inner cavity of the connecting shell 4. The mesh cover 5 is clamped on the upper end surface of the spring clip 11 to ensure that the mesh cover 5 can be opened to clean the hair in the inner cavity of the connecting shell 4.

[0032] Example 2

[0033] See also Figure 2 In order to facilitate the connection shell 4 to adjust the angle in the front-back or left-right direction, the covering plate 3 is a corrugated plastic covering plate. The covering plate 3 can shrink according to the swing of the connection shell 4, effectively ensuring the stability of the connection shell 4.

[0034] Working principle: When in use, the user fits the mesh cover 5 to the face according to the beard on the face, and uses the battery to power the driving motor 10. The driving motor 10 drives the rotating shaft 76 to rotate, and the rotating shaft 76 drives the connecting head 75 to rotate. Through the cooperation of the guide block and the guide groove, the connecting head 75 rotates to ensure that the ball 73 does not slide in the inner cavity of the spherical groove 74. The rotation of the connecting head 75 drives the connecting column 72 to rotate at a required angle. Through the cooperation of the limit groove 71 and the connecting shaft 82, the normal rotation of the connecting shaft 82 is ensured. Through the cooperation of the bearing 81, the stability of the connecting shell 4 is ensured. The connecting shaft 82 drives the rotating rod 83 and the blade 84 to rotate normally, and the blade 84 is ensured to shave the user at a certain angle. In order to shave the beard very cleanly, the user presses the razor to ensure that the floating mesh cover 5 is closely fitted to the user's face, and the distance between the mesh cover 5 and the blade 84 is shorter, thereby ensuring that the user's beard is replaced shorter from the inside.
