Further, the expansion part 120 is made of a flexible material, a plurality of folds 121 are formed on the expansion part 120, the axial direction of the folds 121 is parallel to the length direction of the eyeshade 100, and the folds 121 can be elastically extended or contracted in the length direction, so that the connecting part 110 and the orbit fitting part 130 are away from or close to each other, the overall length of the eyeshade 100 is changed, and the eyeshade is conveniently adjusted to a proper viewing distance in the observation process. In the embodiment shown in the drawings, the bellows portion 120 is in a bellows shape, the entire bellows portion 120 is formed by the pleats 121, and the bellows portion 120 is extended or contracted in the length direction to move the connecting portion 110 and the orbital engaging portion 130 away from or toward each other. The bellows-shaped expansion part 120 is easy to manufacture and low in cost, and the length of the eyecup 100 can be simply and conveniently adjusted by unfolding the folds 121 on the expansion part 120 or folding the folds 121 on the expansion part 120. In other embodiments, the bellows 120 may be formed by alternately connecting the pleats 121 and the non-pleats 121. The material of the expansion part 120 is preferably soft rubber material with elastic deformability.

As an alternative embodiment of the present invention, the interface portion 110, the expansion portion 120, and the orbit fitting portion 130 are integrally formed by a soft rubber material, which may be silicone, tpu, tpe, or the like.

The first connecting portion 141 axially limits the second connecting portion 111, and since the first connecting portion 141 and the second connecting portion 111 are both annular structures, the second connecting portion 111 can still rotate relative to the first connecting portion 141 in the circumferential direction. Therefore, when watching, the eyeshade 100 can be manually rotated in the circumferential direction relative to the ocular lens and stopped at a proper observation angle, and the adaptability is stronger. In the embodiment shown in the drawings, the first connecting portion 141 is a limiting groove provided on the inner wall surface of the connection ring 140, and the first connecting portion 141 is a limiting protrusion provided on the outer wall surface of the connecting portion 110, and the outer diameter of the limiting protrusion is equivalent to the inner diameter of the limiting groove. Because the connecting portion 110 is made of an elastic material, when the connecting portion is assembled, a worker only needs to press the limiting protrusion of the connecting portion 110 to be installed in the connecting ring 140, and the limiting protrusion can be automatically embedded into the limiting groove of the connecting ring 140 under the action of resilience force after the worker looses his hand. The inverted groove structure is assembled in such a way that the free end of the connecting part 110 completely fills the gap between the connecting ring 140 and the eyepiece after the attachment is completed, and the eye mask 100 does not fall off even under the action of a great pulling force. In addition, the interface portion 110 can rotate freely after overcoming a certain damping force in the limiting recess of the connection ring 140. After the eye mask 100 is mounted, if the user needs to adjust the eye mask 100 during use, the eye socket attaching portion 130 of the eye mask 100 can be pinched by hand to rotate in the circumferential direction. When the user stops the glasses while adjusting the angle at which the eyes feel comfortable, the user can watch the glasses 100 while the glasses are attached.

Further, the eye mask 100 further includes a fastening screw 144, and a screw hole 143 through which the fastening screw 144 is screwed is formed on a side wall of the connection ring 140. After the eye cup 100 is screw-fitted to the eyepiece through the attachment ring 140, the attachment ring 140 is further secured to the eyepiece by tightening the set screw 144, preventing the screw from loosening.
