Two pieces of vertical settings of lens 203 are between two vertical limiting plate 201 boards, and the slider 2031 that is located the vertical setting of the equal fixedly connected with in both sides in the vertical side of lens 203 between two vertical limiting plate 201, slider 2031's shape be with the shape and the size complex cube of first spout 2011, slider 2031 can with first spout 2011 sliding fit, and lens 203 can reciprocate along with slider 2031 along the spout.
Two second sliding grooves 2021 are respectively arranged on the opposite wall surfaces of the two transverse limiting plates 202, and the two second sliding grooves 2021 which are horizontally arranged are concave cubic grooves on the limiting plates.

The attraction plate 303 is an L-shaped iron plate, the attraction plate 303 is located at a position where the long vertical limiting plate 201 and the long horizontal limiting plate 202 are tightly attached, the long vertical limiting plate 201 and the long horizontal limiting plate 202 are respectively provided with a notch, and when the long vertical limiting plate 201 and the long horizontal limiting plate 202 are tightly attached, the shape formed by matching the two notches is consistent with the shape of the attraction plate 303.
the first driving mechanism 301 includes two first electromagnets 3011. A first electromagnet 3011 is fixed on the upper end of the lens 203 between the two vertical limiting plates 201.
the second driving mechanism 302 includes a spring 3022, a pull plate 3023, and two second electromagnets 3021. The pulling plate 3023 is vertically and fixedly arranged on one side of the two transverse limiting plates 202 far away from the attraction plate 303, and the vertically arranged second electromagnets 3021 are fixed at one ends of the two lenses 203 positioned between the two transverse limiting plates 202 and close to the attraction plate 303. Two ends of the lens 203, which are located between the two transverse limiting plates 202 and are close to the pull plate 3023, are both provided with springs 3022, one end of each spring 3022 is fixedly connected with the lens 203, and the other end of each spring 3023 is fixedly connected with the pull plate 3023.
The first electromagnet 3011 generates magnetism after being energized, the attraction plate 303 attracts the first electromagnet 3011 towards a direction close to the attraction plate 303 under the interaction of magnetic force, the first electromagnet 3011 drives the lens 203 fixedly connected with the first electromagnet 3011 to move upwards to one end, close to the attraction plate 303, of the first chute 2011 along the first chute 2011, and at this time, a part of the sliding block 2031 is still in sliding fit with the first chute 2011 on the short vertical limiting plate 201. When the lens 203 is attracted to the end of the first chute 2011 close to the attraction plate 303, the projection of the lens hole 101 toward the lens assembly 2 falls on the lens 203 attracted by the attraction plate 303 between the two vertical limiting plates 201, and the lens 203 can project the VR screen to the eye of the wearer.
Similarly, when the second electromagnet 3021 is energized, the attraction plate 303 attracts the lens 203 fixed to the second electromagnet 3021 to the end of the second sliding groove 2021 close to the attraction plate 303, and at this time, a portion of the slider 2031 is still in sliding engagement with the second sliding groove 2021 of the short lateral restriction plate 202. When the lens 203 is attracted to the end of the second chute 2021 close to the attraction plate 303, the projection of the lens hole 101 toward the lens unit 2 falls on the lens 203 attracted by the attraction plate 303 between the two lateral restriction plates 202, and the lens 203 can project the VR screen to the eye of the wearer.
After the first electromagnet 3011 is powered off, the lens 203 fixedly connected to the first electromagnet 3011 moves downward along the first chute 2011 to the lower end of the first chute 2011 under the action of gravity.
after the second electromagnet 3021 is powered off, the lens 203 fixedly connected to the second electromagnet 3021 moves horizontally along the second sliding slot 2021 to the end of the second sliding slot 2021 close to the pull plate 3023 under the pulling force of the spring 3022.
The lens adjusting mechanism switches the lens 203 by controlling the first electromagnet 3011 and the second electromagnet 3021 to be turned on and off. After the lens 203 is switched, the ciliary muscle of the glasses of the wearer can adjust the tightness degree along with the switching of the lens 203 due to the change of the curvature, thereby relieving the visual fatigue of the wearer and preventing the ciliary muscle from being always in the tightness degree of the same degree. At the same time, when the lens 203 is switched, the distance between the lens 203 and the lens hole 101 is also changed, and the ciliary muscle can be forced to adjust the tightness degree of the muscle under the condition of changing the visual distance.
In a specific embodiment, a first buffer magnet 204 is fixed at the lower end of the first slide groove 2011, a first buffer magnet 204 is fixed at one end of the second slide groove 2021 close to the pull plate 3023, and a rubber pad 205 is fixed at one end of the first buffer magnet 204 close to the lens 203. A second buffer magnet 2032 is fixed to both the end of the slider 2031 in the first runner 2011 away from the attraction plate 303 and the end of the slider 2031 in the second runner 2021 away from the attraction plate 303. The magnetically repulsive poles of the first buffer magnet 204 and the second buffer magnet 2032 are disposed opposite to each other.
After the electromagnet loses magnetic force due to power failure, the lens 203 moves along the first slide groove 2011 or the second slide groove 2021 under the action of gravity or the pulling force of the spring 3022, and there is a risk that the lens 203 is damaged by directly sliding the lens 203 without any protective measures. The repulsive force between the first buffer magnet 204 and the second buffer magnet 2032 can reduce the speed of the lens 203 when the lens is close to the lowest end of the chute, and the rubber pad 205 fixed above the first buffer magnet 204 can reduce the collision force received by the slider 2031 and can protect the first buffer magnet 204 to a certain extent. The force between the first buffer magnet 204 and the second buffer magnet 2032 is much smaller than the force between the iron plate and the electromagnet, which prevents the switching of the lens 203 from being affected.
In a specific embodiment, two ends of the long transverse limiting plate 202 and two ends of the long vertical limiting plate 201 are respectively provided with a circular through hole, and the through holes are internally provided with fixing screws 4.

The fixing screw 4 in the through hole at the end of the transverse limiting plate 202 far away from the attraction plate 303 is rotated clockwise, so that the fixing screw can be in threaded fit with the transverse limiting plate 202 more tightly.
The counterclockwise rotation of the fixing screw 4 in the through hole at the lower end of the vertical position limiting plate 201 enables the screw thread fit with the vertical position limiting plate 201 to be more tight.
