[0017] Please refer to Figure 1 - Figure 2 , the present utility model provides a technical solution: a face recognition device with good positioning effect, including a face recognition device 1, a fixed frame 11 is fixedly installed in the middle of the rear side of the face recognition device 1, and a support bar 12 is further included. The support bar 12 is slidably connected to the fixed frame 11. A fixed frame 2 is arranged inside the fixed frame 11, a rotating roller 21 is rotatably connected inside the fixed frame 2, and the rotating roller 21 is in rolling connection with the upper surface of the support bar 12.

[0018] In this technical solution, by sliding the support bar 12 and the fixed frame 11, and through the rotating roller 21 inside the fixed frame 2, the fixed frame 11 can be smoothly pushed to move outside the support bar 12, facilitating the adjustment of the usage position of the face recognition device 1.

[0019] In this embodiment, two groups of springs 13 are arranged inside the fixed frame 11. A first rack 14 is horizontally and fixedly connected to the bottom side of the support bar 12, and a second rack 15 is horizontally and fixedly connected to the inner wall of the bottom end of the fixed frame 11. The first rack 14 meshes with the second rack 15.

[0020] In this technical solution, after the usage position of the face recognition device 1 is adjusted, when the fixed frame 11 is released, the elastic force of the spring 13 can push the fixed frame 11 upward, so that the second rack 15 on the inner wall of the bottom end of the fixed frame 11 meshes with the first rack 14 on the bottom side of the support bar 12, which can automatically limit and fix the fixed frame 11, thereby automatically positioning the face recognition device 1, which is convenient and fast.

[0021] In this embodiment, limiting grooves 23 are symmetrically formed on the front and rear sides of the inner wall of the top end of the fixed frame 11. Limiting rods 22 are symmetrically installed on the front and rear sides of the upper surface of the fixed frame 2. The upper ends of the limiting rods 22 are slidably connected to the limiting grooves 23. The two groups of springs 13 are respectively sleeved outside the two groups of limiting rods 22. The sizes of the limiting rods 22 and the limiting grooves 23 match each other.

[0022] In this technical solution, by the sliding connection between the limiting rod 22 and the limiting groove 23, on the one hand, the usage stability of the fixed frame 2 can be improved, and on the other hand, the spring 13 can be limited to prevent the spring 13 from tilting during the compression and extension processes, affecting the usage effect.

[0023] When a face recognition device with good positioning effect is in use, the two ends of the support bar 12 are fixed at designated positions. When the usage position of the face recognition device 1 needs to be adjusted, the fixed frame 11 is pressed downward, so that the second rack 15 on the inner wall of the bottom end of the fixed frame 11 is separated from the first rack 14 on the bottom side of the support bar 12, unlocking the fixed frame 11. Through the rotating roller 21 rotating inside the fixed frame 11, the fixed frame 11 can be smoothly pushed to move, adjusting the usage position of the face recognition device 1. After the usage position of the face recognition device 1 is adjusted, the fixed frame 11 is released, and the elastic force of the spring 13 can push the fixed frame 11 upward, so that the second rack 15 on the inner wall of the bottom end of the fixed frame 11 meshes with the first rack 14 on the bottom side of the support bar 12, which can automatically limit and fix the fixed frame 11, thereby automatically positioning the face recognition device 1, which is convenient and fast.
