AI Technical Summary
The combination of the drilling slide and the fixed tool groove of the existing haircut trimmer is relatively rigid, which leads to inconvenient movement of the drilling component and affects normal operation. The material of the drilling slide is hard and cannot provide a suitable buffering effect, resulting in easy lag during the movement of the drilling component.
An elastic haircut trimmer movable knife guide slider is designed. By using an interference fit between the drilling knife slider and the knife guide groove, the elasticity of the drilling knife slider is used to expand or deform the knife guide groove. When the knife guide groove is restored, the tightening force is generated, which improves the sliding smoothness of the drilling knife assembly, and a projecting part is provided on the upper and lower parts of the drilling knife slider to increase elasticity.
Through this design, the noise of sliding of the movable knife assembly is reduced, the smooth sliding of the movable knife assembly is improved, the lag during movement of the movable knife assembly is reduced, and the normal operation of the haircut trimmer is ensured.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figure 1 , Figure 2 As shown, a flexible movable blade guide slider of a hair clipper comprises a movable blade assembly 3 and a fixed blade assembly 4. The bottom of the fixed blade assembly 4 is fixedly connected to a shell 5, the interior of the shell 5 is fixedly connected to a connecting mechanism 1, the surface of the fixed blade assembly 4 is movably connected to a motor mechanism 2, the left and right parts of the front side of the movable blade assembly 3 are fixedly connected to connecting blocks 12, and a fixed blade guide groove 11 is provided in the middle of the front side of the fixed blade assembly 4.
[0024] It should be noted that, through the motorized mechanism 2, the connecting block 12 can be driven to swing horizontally and linearly left and right, thereby driving the movable knife assembly 3 to move horizontally and linearly on the fixed knife assembly 4, thereby trimming the hair.
[0025] like Figure 1-Figure 4 As shown, the motorized mechanism 2 includes a movable knife slider 22, the upper and lower sides of which are movably connected to the upper and lower sides of the fixed knife guide groove 11, elastic openings 23 are provided on the left and right parts of the movable knife slider 22, a pushing groove 25 is provided at the middle position of the bottom of the movable knife slider 22, a pushing block 21 is rotatably connected to the middle position of the connecting mechanism 1, and a movable knife spring 24 is fixedly connected to the left and right sides of the pushing block 21.
[0026] It should be noted that by starting the DC motor arranged inside the connecting mechanism 1, the pushing block 21 will be driven to move back and forth left and right. Moving knife springs 24 are arranged on the left and right sides of the pushing block 21 to ensure the smooth back and forth movement of the pushing block 21. The upper part of the pushing block 21 is located in the pushing groove 25. During the movement of the pushing block 21, the moving knife slider 22 will be driven to swing horizontally and linearly left and right, thereby driving the moving knife assembly 3 to move horizontally and linearly on the fixed knife assembly 4, so that the hair can be trimmed.
[0027] like Figure 1-Figure 4As shown, the push groove 25 is in the shape of a square groove, and the length of the push groove 25 is slightly greater than the length of the upper portion of the push block 21 .
[0028] It should be noted that the upper portion of the push block 21 is located in the push groove 25 , and during the movement of the push block 21 , the movable knife slide block 22 will be driven to swing horizontally and linearly left and right.
[0029] like Figure 1-Figure 4 As shown, the surface size of the elastic opening 23 is slightly larger than the surface size of the connecting block 12, and the lower notch of the elastic opening 23 is opened to the root corner.

The upper part of the pushing block 21 is located in the pushing groove 25. During the movement of the pushing block 21, the moving knife slider 22 will be driven to swing horizontally and linearly left and right. The moving knife slider 22 and the fixed knife guide groove 11 are arranged with interference fit, that is, the elasticity of the moving knife slider 22 is used to expand or deform the fixed knife guide groove 11. When the fixed knife guide groove 11 is restored, a clamping force is generated on the moving knife slider 22, so that the fixed knife guide groove 11 is The groove 11 and the movable knife slider 22 are better connected together to reduce the noise of the sliding of the movable knife assembly 3. At the same time, the movable knife slider 22 has protruding parts on the upper and lower parts, which cooperate with the fixed knife guide groove 11, and are elastic on the upper and lower parts, so that the movement of the movable knife slider 22 is smoother. The two connecting blocks 12 arranged on the movable knife assembly 3 are located inside the elastic opening 23, and the lower notch of the elastic opening 23 is opened to the root clearing angle. When the connecting block 12 is installed, the upper and lower corners of the elastic opening 23 are still elastic, which does not affect the normal operation of the movable knife slider 22, and then drives the movable knife assembly 3 to move horizontally and linearly on the fixed knife assembly 4, so that the hair can be trimmed.
