[0002] The life in the city is relatively monotonous now. Usually, people spend a long time using computers at work or using mobile phones for a long time after going home. And in the study life, they face books at a relatively short distance for a long time. Because the eyes focus on a relatively near or far focal length for a long time, or because they focus on a similar focal length for a long time, the eye adjustment ability gradually becomes worse and the eyesight becomes lower.

[0003] A vision training device is an instrument that can improve eyesight. When in use, it trains the muscles around the eyes. However, the existing vision training devices still have certain defects. The visual target movement of most vision training devices still uses a manual rotating dial to move the visual target back and forth. The adjustment efficiency is low, and there is an unstable structure after movement. And the long-term rotating work is easy to cause fatigue. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a visual target moving component in a vision training device. Through the set structure of a motor - threaded rod - sleeve and the sliders on both sides thereof, the threaded rod can be rotated through the motor structure on one side to drive the sleeve to move in the middle groove, and the sliders on both sides can move in the side grooves. Since both the slider and the chute are cross-shaped structures, during the sliding process, the cross-shaped structure can play a fixing role to prevent the angle code and the visual target from falling. Therefore, the visual target can be fixedly connected with the L-shaped angle code to achieve the effect of quick connection, and the visual target can also achieve the function of adjusting the distance, which is convenient for vision training.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A visual target moving component in a vision training device, including a base, a sliding rod is fixed at the top end of the base, a positioning block is fixed at the top end of the sliding rod, a fixed rod structure is fixed in the middle of the positioning block, and an installation plate is fixed at the end of the fixed rod. A positioning plate is fixed at the bottom end of the installation plate, a motor is fixed at the end of the positioning plate. A middle groove is opened in the middle of the bottom end of the positioning plate, and side grooves are opened at both ends of the middle groove. The output end of the motor is fixedly connected with a threaded rod, the threaded rod is arranged in the middle groove, a sleeve is sleeved outside the threaded rod, a slider is arranged in the side groove, the bottom end of the slider is fixedly connected with the sleeve, an L-shaped angle code is fixed at the bottom end of the sleeve, and a visual target is fixed on the angle code.

[0006] As a preferred technical solution of the utility model, scale marks are opened on the side walls of the sliding rod and the positioning plate.

[0007] As a preferred technical solution of the present utility model, both the side groove and the slider are cross-shaped structures.

[0008] As a preferred technical solution of the present utility model, a blocking block is provided on one side of the positioning plate, and the blocking block is fixed outside the middle groove.

[0009] As a preferred technical solution of the present utility model, a circular groove structure is provided in the middle of the positioning block, a square groove penetrates through the outside of the circular groove, and the fixing rod is fixed in the circular groove by interference fit.

[0010] As a preferred technical solution of the present utility model, a threaded structure meshing with the threaded rod is provided inside the sleeve.
