[0025] Embodiment 1

[0026] As Figures 1 - 5 shown, the hair cutting blade assembly in this embodiment mainly consists of a moving blade unit 10, a fixed blade unit 20, and a guiding unit disposed between the moving blade unit 10 and the fixed blade unit 20. The shearing hair cutting action is realized through the reciprocating movement of the moving blade unit 10 relative to the fixed blade unit 20.

[0027] Among them, the moving blade unit 10 includes a moving blade body 11 and a moving blade seat 12, and the fixed blade unit 20 includes a fixed blade body 21 and a fixed blade seat 22.

[0028] Specifically, the guiding unit includes a substrate 30 and a movable plate 40. The substrate 30 is fixedly connected to the fixed blade unit 20, and the movable plate 40 is connected to the moving blade unit 10. The moving blade unit 10 drives the movable plate 40 to make a linear reciprocating movement, thereby realizing the shearing action with the fixed blade unit 20.

[0029] Among them, a guiding hole 31 is provided in the upper half of the substrate 30, and a limiting plate 32 is provided in the guiding hole 31. The two ends of the movable plate 40 protrude outward to form limiting ends 41. The limiting ends 41 are located on both sides of the limiting plate 32 and cannot pass through the limiting plate 32. Thus, the movable plate 40 is disposed in the guiding hole 31 and can perform a linear reciprocating movement within a certain range along the guiding hole 31.

[0030] Moreover, the width of the upper half of the substrate 30 is the same as the width of the guiding hole 31, that is, their inner and outer walls are in contact, forming a stable guide.

[0031] Moreover, a connection block 42 is provided at the opposite end of the limiting end 41, and the connection block 42 is used to connect with the moving knife unit 10. Thus, the upper half of the substrate 30 generally forms an I-shaped structure and straddles the limiting plate 32.

[0032] Wherein, a positioning groove 23 is provided on the fixed knife body 21, the upper half of the substrate 30 is arranged in the positioning groove 23, the position of the guiding hole 31 corresponds to the position of the positioning groove 23, the substrate 30 is arranged between the fixed knife body 21 and the fixed knife seat 22, and the fixed knife seat 22 is connected to the lower end of the substrate 30.

[0033] Meanwhile, the substrate 30 is also arranged between the moving knife body 11 and the fixed knife body 21. The moving knife body 11 is connected to the upper end of the substrate 30. The moving knife body 11 is arranged between the substrate 30 and the moving knife seat 12. The connecting body is connected to the moving knife body 11 and the moving knife seat 12 through a locking member such as a bolt.

[0034] It should be noted that in the present utility model, the connection methods not described between the components can all adopt the commonly used connection methods in the field.

[0035] The scope of the present utility model is not limited by the described embodiments above, but is limited by the appended claims and their equivalents.
