The lens assembly includes a fixing plate, a clamping column symmetrically arranged on the fixing plate, and a covering ring arranged on the fixing plate. A lens is fixedly installed in the covering ring, and the outer side of the lens is subjected to the covering ring. The covering is used to protect the outer side of the lens. The clamping column can clamp the covering ring and is used to limit the lens set in the covering ring through the fixing plate and the clamping column. The lens in the lens assembly set in the receiving groove 13 on one side of the switching groove 12 is a convex lens, and the lens in the lens assembly set in the receiving groove 13 on the other side of the switching groove 12 is a concave lens. The switching groove 12 is provided with a swing ring 14, a switching component symmetrically arranged in the mounting block 1, a driving component 2 arranged in the handle 11, and an adjusting component 3 arranged in the handle 11;

[0043] The switching component includes a trigger component 4 and a push-up component 5, and the trigger component 4 and the push-up component 5 are interconnected;

[0044] The ejection component 5 includes an ejection block 51, a guide cylinder 52 arranged on the ejection block 51, a guide groove 53 arranged on the inner wall of the guide cylinder 52, a fixed cylinder 54 arranged on the outer side of the guide cylinder 52, a piston 541 arranged in the fixed cylinder 54, a support rod arranged in the middle area of ​​the side of the piston 541 close to the ejection block 51, a guide plate 542 arranged at the end of the support rod away from the piston 541, and a guide block 543 arranged on the guide plate 542. The trigger component 4 is driven by the swing ring 14 to increase the internal pressure of the fixed cylinder 54, and the piston 541 drives the guide plate 542 to move, so that the guide cylinder 52 rotates, so as to make the ejection block 51 push the lens assembly toward the swing ring 1 4, an eccentric portion is provided on the pushing block 51, the pushing component 5 is arranged in the receiving groove 13, a support rod is fixedly installed on the side of the pushing block 51 away from the guide cylinder 52, the support rod rotates in the receiving groove 13, a protective cylinder is provided on the end of the fixed cylinder 54 away from the guide cylinder 52, the protective cylinder is fixedly installed on the groove wall of the receiving groove 13, and a spring piece 1 is symmetrically provided on the bottom of the receiving groove 13, and the other end of the spring piece 1 is connected to the side of the fixed plate away from the lens. When the pushing block 51 rotates, the eccentric portion will gradually push the fixed plate, at this time, the spring piece 1 is gradually stretched and deformed, and as the pushing block 51 continues to rotate, the eccentric portion will gradually separate from the fixed plate, and at this time, the fixed plate is reset under the pull of the spring piece 1.

[0045] A trigger slot 15 is arranged in the switching slot 12, and a pneumatic slot 16 is arranged in the trigger slot 15. The trigger component 4 includes a trigger block 41 arranged in the trigger slot 15, a guide portion 411 arranged at one end of the trigger block 41 close to the pneumatic slot 16, and a trigger plate symmetrically arranged on the trigger block 41. A second spring is arranged on the trigger plate, and one end of the second spring away from the trigger plate is connected to the trigger slot 15. When the swing ring 14 is not in contact with the trigger block 41, under the action of the second spring, the trigger block 41 extends into the switching slot 12. When the swing ring 14 moves into the switching slot 12, the swing ring 14 will press the trigger block 41, causing the second spring to deform and stretch, and the trigger block 41 will move toward the direction of the pneumatic slot 16.

[0046] A moving cylinder 42 is arranged in the pneumatic groove 16, a moving groove 421 is arranged in the middle area of ​​the moving cylinder 42, a piston 43 is symmetrically arranged on the moving cylinder 42, a flow hole 431 is opened in the middle of the piston 43, the piston 43 and the pneumatic groove 16 form a first air cavity, and the first air cavity is connected to the end of the fixed cylinder 54 away from the guide cylinder 52 through a pipeline.

[0047] A moving rod 44 is arranged in the moving cylinder 42, a piston three 441 is symmetrically arranged on the moving rod 44, and a moving block 45 is arranged in the middle area of ​​the moving rod 44. The moving block 45 passes through the moving groove 421, and the moving block 45 extends to the outside of the moving cylinder 42 at one end away from the moving rod 44. The piston three 441 and the inner cavity of the moving cylinder 42 form a second air cavity, and the first air cavity is connected to the second air cavity through the flow hole 431.

[0048] A swinging groove 17 is arranged in the pneumatic groove 16, and a swinging rod 46 is arranged on the moving cylinder 42. A telescopic rod 47 is slidably arranged in the swinging rod 46, and a top ball 48 is arranged at one end of the telescopic rod 47 away from the swinging rod 46. One end of the swinging rod 46 is hingedly matched with the middle area of ​​the outer side wall of the moving cylinder 42, a baffle is arranged on the outside of the swinging rod 46, and a spring 1 is sleeved on the outside of the swinging rod 46, one end of the spring 1 is connected to the baffle, and the end of the spring 1 away from the baffle is connected to the top ball 48.

[0049] The inner wall of the swing ring 14 is symmetrically provided with mounting grooves, and a spring piece three 141 is arranged in the mounting groove. A connecting rod 142 is arranged on the outer side of the swing ring 14, and the middle area of ​​the spring piece three 141 is arranged on the outer side of the swing ring 14. When the lens assembly moves toward the direction of the swing ring 14 under the drive of the switching component, the outer side of the covering ring will contact the spring piece three 141. At this time, the spring piece three 141 will be deformed, and at the same time, the spring piece three 141 symmetrically arranged in the swing ring 14 will apply a clamping force to the covering ring. When the switching component no longer applies a pushing force to the lens assembly, at this time, under the action of the elastic force of the spring piece one, the fixed plate will gradually reset. Since the covering ring and the lens arranged in the covering ring are subjected to the clamping force of the spring piece three 141 at this time, the covering ring is separated from the fixed plate, and the lens will be installed in the swing ring 14.

[0050] During use, first hold the handle 11, then adjust the adjustment component 3 to select a training mode that suits you, and then manually drive the drive component 2;

[0051] At this time, the swing ring 14 will drive the lens to extend out from the switching slot 12, and the user can start to train his ciliary muscle;

[0052] When the driving component 2 drives the swing ring 14 and the lens in the swing ring 14 to move back into the switching groove 12, the swing ring 14 will push the trigger block 41, so that the guide part 411 pushes the moving block 45, and the moving block 45 will slide in the moving groove 421. When the moving block 45 moves to the limit position of the moving groove 421, the trigger block 41 will make the moving cylinder 42 move in the pneumatic groove 16 through the moving block 45, and the second piston 43 will push the gas in the first air cavity, so that the gas pressure in the first air cavity increases;

[0053] At this time, the piston 1 541 will move in the fixed cylinder 54, thereby pushing the guide plate 542 through the piston 1 541, so that the guide plate 542 descends, and then the guide block 543 will slide in the guide groove 53, so that the guide cylinder 52 rotates, and the rotation of the guide cylinder 52 will drive the push block 51 to rotate;

[0054] At this time, the push block 51 will push the fixed plate, so that the covering ring and the lens move toward the swing ring 14. At this time, the lens in the swing ring 14 will be squeezed out of the swing ring 14 by another lens and contact the fixed plate again. When the covering ring enters the inner ring of the swing ring 14, the spring piece 3 141 will be deformed under the pressure of the covering ring, and the spring piece 3 141 will clamp the covering ring.

[0055] When the push block 51 rotates one circle, the fixed plate will be reset under the action of the spring piece 1, and the covering ring in the fixed plate will be separated from the fixed plate under the clamping of the spring piece 3 141. Then, under the drive of the driving component 2, the swing ring 14 component extends out of the switching slot 12. At this time, the trigger block 41 is reset under the action of the spring piece 2, and the gas pressure in the first air chamber will flow through the hole 431 to push the piston 2 43, so that the moving rod 44 moves in the direction opposite to the previous moving direction.

[0056] At the same time, when the moving cylinder 42 is moving, the swing rod 46 will gradually approach the telescopic rod 47, so that the telescopic rod 47 will shrink into the swing rod 46. At this time, the spring 1 is deformed and compressed. When the moving cylinder 42 drives the swing rod 46 to swing to a certain position, the telescopic rod 47 will retract again under the elastic force of the spring 1, and the top ball 48 will slide along the arc-shaped groove wall of the swing groove 17. The swing rod 46 and the telescopic rod 47 are driven to swing by the moving cylinder 42, so that the moving cylinder 42 will not move in the pneumatic groove 16 when the pressure in the first air chamber increases and the trigger block 41 is reset.

[0057] When the swing ring 14 enters the switching slot 12 again and pushes the trigger block 41, the switching component will replace the lens in the current swing ring 14, thereby enabling the user to switch between the concave lens and the convex lens when training the ciliary muscle.

[0058] Example 2

[0059] Reference Figure 9-11 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0060] The adjusting component 3 includes two adjusting rods 31, a limiting groove 311 arranged at one end of the adjusting rod 31, a plug-in groove 312 arranged on the adjusting rod 31, and a plug-in rod 32 arranged in the plug-in groove 312. A sliding groove is provided at one end of the handle 11 connected to the mounting block 1, and the adjusting rod 31 is slidably installed in the sliding groove. The connecting rod 142 extends to the position of the limiting groove 311, and the connecting rod 142 is limited by the limiting groove 311, so as to realize the position of moving the adjusting rod 31, thereby realizing the purpose of controlling the swing amplitude of the swing ring 14. A card plate is provided at one end of the plug-in groove 312 for plugging the plug-in groove 312, and a card slot is provided at the bottom of the plug-in groove 312. The card plate is arranged in the card slot. The plug-in rod 32 is a semi-cylindrical structure, and the plug-in groove 312 is adapted to the plug-in rod 32.

[0061] A guide rod 33 is arranged in the handle 11, and a groove is provided on the side wall of the guide rod 33. The end of the plug-in rod 32 away from the adjusting rod 31 is inserted in the groove, and a section of the plug-in rod 32 inserted into the groove is provided with a key groove 321. A knob is arranged at the end of the handle 11 away from the mounting block 1, and a limit rod 34 is arranged on the knob. The limit rod 34 is slidably arranged in the key groove 321. A slider is provided at the end of the plug-in rod 32 away from the baffle, and the slider is slidably arranged in the key groove 321. The limit rod 34 passes through the slider, and the slider is used to limit and guide the limit rod 34.

[0062] During use, when the user performs monocular training, the knob is rotated so that the limit rod 34 drives the plug rod 32 to rotate in the plug slot 312 of one of the adjustment rods 31. At this time, the driving component 2 will push only one adjustment rod 31 through the plug rod 32. At this time, the connecting rod 142 in the limit slot 311 on the pushed adjustment rod 31 will drive the swing ring 14 to swing to the switching slot 12;

[0063] When the user is training both eyes, the knob is turned so that the plug-in rod 32 is located in the plug-in slot 312 of the two adjustment rods 31. At this time, the driving component 2 will push the plug-in rod 32 so that the plug-in rod 32 drives the two adjustment rods 31 to move, and the switching slot 12 is switched from the position where the two swing rings 14 symmetrically arranged in the mounting block 1 swing simultaneously, so that the user can choose monocular training or binocular training when training the ciliary muscles.

[0064] The remaining structures are the same as those of Example 1.

[0065] Example 3

[0066] Reference Figure 1-12 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that:

[0067] The driving component 2 includes a driving block 21. A driving groove 111 is opened on the side wall of one side of the handle 11. The driving block 21 is slidably set in the driving groove 111. The driving block 21 is in a T-shaped structure. The limiting rod 34 passes through the driving block 21. The side walls on both sides of the driving groove 111 are arrayed with teeth.

[0068] The driving component 2 also includes an active rod 22 arranged in the driving block 21, an active block 23 arranged in the middle area of ​​the active rod 22, driven rods 24 symmetrically arranged on both sides of the active block 23, and a driven block 25 arranged at one end of the two driven rods 24 close to each other.

[0069] During use, the user first holds the handle 11, and then manually presses the active rod 22, at which time the spring 2 is deformed and compressed, and then the active block 23 avoids the driven block 25, so that the two driven blocks 25 gradually approach each other under the push of the spring 3, and at this time, the end of the driven rod 24 extending out of the driving block 21 will be retracted into the driving block 21, and the driving block 21 will be pushed at this time, and the driving block 21 will drive the plug rod 32 to move;

[0070] When the distance between the lenses in the two swing rings 14 matches the user's eye distance, the active rod 22 is released, and the spring 2 pushes the active block 23 to return to its original position, forcing the driven blocks 25 on both sides to gradually move away from each other. At this time, the spring 3 is deformed and compressed, and one end of the driven rod 24 away from the driven block 25 extends out of the driving block 21 and engages with the teeth on the side wall of the driving groove 111. At this time, the user can start to train his or her ciliary muscle.

[0071] The remaining structure is the same as that of Example 2.
