Therefore, they should not be construed as limitations on this utility model. Example 1

[0021] Please seeFigures 1-6 This utility model provides a technical solution: a remote image reading and writing station, including an objective lens housing (1), an eyepiece housing (2), an eyepiece (3), an objective lens (10), and a vertical rod (4); the objective lens housing (1) and the eyepiece housing (2) are connected by a damping pivot (19), and the user can fold and unfold the objective lens housing and the eyepiece housing by rotating the pivot.

[0022] The support member (9) consists of a hinge plate one (11), a hinge plate two (12), a rotating shaft (13), and a torsion spring (14). The hinge plate one (11) is fixedly connected to the objective lens housing (1), and the hinge plate two (12) is fixedly connected to the eyepiece housing (2). The hinge plate one (11) and the hinge plate two (12) are connected by the rotating shaft (13). The torsion spring (14) passes through the rotating shaft (13). When the objective lens housing (1) and the eyepiece housing (2) are unfolded or folded, the torsion spring (14) provides elastic support force, which facilitates the smooth opening and closing of the eyepiece housing (2).

[0023] Users can fold or unfold the objective lens housing (1) and the eyepiece housing (2) by manually rotating the connecting part between them. During folding, the elastic force provided by the torsion spring (14) locks the objective lens housing (1) and the eyepiece housing (2) in the closed state, preventing the eyepiece housing (2) from opening naturally due to external force. When unfolding, the supporting force provided by the torsion spring (14) helps the eyepiece housing (2) to open smoothly and maintains the appropriate angle between the objective lens housing and the eyepiece housing.

[0024] A vertical rod (4) is provided on the back of the objective lens housing (1). The vertical rod (4) serves to support the upper structure of the objective lens housing (1) and the eyepiece housing (2) to ensure the stability of the entire device. The inner cavity of the vertical rod (4) is designed as a hollow structure and is equipped with a slide (17) to facilitate the installation and adjustment of other components.

[0025] The eyepiece (3) is installed inside the eyepiece housing (2), and the objective lens (10) is installed inside the objective lens housing (1). The objective lens (10) is responsible for reflecting the books on the desk into the eyepiece (3), and then the eyepiece (3) reflects the image into the user's eyes. In this way, the user can observe the books on the desk from a distance through the eyepiece (3) and avoid eye fatigue and damage caused by close reading. Example 2

[0026] In this embodiment, the vertical rod (4) adopts a hollow structure and a slide rail (17) is designed inside the vertical rod. The slide rail (17) is used to guide the adjustment components or install the adjustment device. The design of the slide rail simplifies the installation process of the equipment and improves the stability and reliability of the vertical rod.

[0027] In this embodiment, the torsion spring (14) not only provides elastic support but also has an adjustable function. Users can adjust the tightness of the torsion spring according to their personal needs to change the opening and closing force of the device. This ensures that different users get the best support effect and improve comfort when using the device. Example 3
