A support assembly 4 is provided inside the placement groove 6. The number of support assemblies 4 is two. The support assembly 4 includes a left support column 401 and a right support column 402. The left support column 401 and the right support column 402 are hollow structures. A left support rod 409 is provided inside the left support column 401. Baffles are provided at both ends of the left support rod 409. A right support rod 410 is provided inside the right support column 402. Baffles are provided at both ends of the right support rod 410. The diameter of the baffle is slightly smaller than the inner wall of the left support column 401 and the right support column 402.

[0023] Working principle: When in use, the utility model adjusts the height of the device through the support component 4, and when the device is not needed, the fixing component 3 is used to fix the vision trainer 2. First, unscrew the fixing block 5 to release the restriction on the support component 4, and then rotate the support component 4 to be perpendicular to the bottom plate 1 by flipping the angle of the crossbeam, and then energize the electromagnet disk 411. The electromagnet disk 411 after energization generates magnetism, and fixes the support component 4 through the magnets 412 at both ends of the crossbeam, and then turn the second knob 403, the rotating rod 404 rotates to drive the first left fixed plate 407 and the second left fixed plate 408 to move to both sides, and release the fixation of the left support rod 409. The rotation of the rotating rod 404 also drives the first right fixed plate 405 and the second right fixed plate 406 to move to both sides, and releases the fixation of the right support rod 410. At this time, pull the left support rod 409 and the right support rod 410. When the left support rod After adjusting the length of 409 and the right support rod 410, turn the second knob 403 again, the first left fixing plate 407 and the second left fixing plate 408 move toward the middle, and the first right fixing plate 405 and the second right fixing plate 406 move toward the middle. When they contact the left support rod 409 and the right support rod 410, the support assembly 4 is fixed. Then turn the first knob 306, and the rotating shaft 305 rotates with the first knob 306, thereby driving the gear 302 to rotate. The rotation of the gear 302 drives the tooth plate 303 to rotate, and the tooth plate 303 drives the limit plate 304 to move from the top of the vision trainer 2 to both sides. When the limit plate 304 completely leaves the vision trainer 2, the vision trainer 2 can be removed and used.
