Background
Students need to write and read often long-time ground-lodging cases. In order to satisfy writing and reading on a desk and hand-eye coordination, people have to look at the desk surface with eyes in a head-down posture. And the long-time use of the head-lowering posture can cause the cervical vertebra and the back to be sour and swollen and tired, and bring cervical vertebra diseases and other health hazards. One current solution is to tilt the table top upward in an attempt to reduce the angle of the head. However, if the inclination of the table top is small, the head still needs to be kept in a low posture; if the inclination is larger, the user is tired quickly because the user lacks upward force support during writing although large-angle head lowering can be avoided. This does not solve the problem well.

Detailed Description
The present invention will be described in detail with reference to specific embodiments, which are based on the present invention, and detailed embodiments and specific operation procedures are provided.
As shown in fig. 1, 2 and 3, a head-up writing and reading tool fixed on a desk 1 includes: the head-up writing and reading tool comprises a concave cylindrical mirror 2, a supporting and connecting mechanism 3 and a fixed seat 4, wherein one end of the supporting and connecting mechanism 3 is connected with the concave cylindrical mirror 2, and the other end of the supporting and connecting mechanism 3 is connected with the fixed seat 4, and the head-up writing and reading tool is kept stable. The concave cylindrical mirror 2 comprises a mirror frame 22 and a mirror surface 21, and is horizontally supported above the desk 1 in a prone position, and the mirror surface 21 is tightly attached to the mirror frame 22.
Preferably, the support connecting mechanism 3 includes two torque hinges (comments) 31 and a supporting plate 32, one end of the support connecting mechanism 3 is connected to the lens holder 22 of the concave cylindrical mirror 2 through one of the torque hinges 31, and the other end of the support connecting mechanism 3 is connected to the fixing seat 4 through the other torque hinge 33. The supporting plate 32 comprises a chute plate 322, a telescopic plate 321 and an adjusting lock 323, wherein the lower end of the telescopic plate 321 is inserted into the chute plate 322 which is tightly matched with each other in a sliding manner, and the adjusting lock 323 is arranged in a sliding fit interval between the telescopic plate 321 and the chute plate 322.
Preferably, the head-up writing and reading tool is fixedly installed at the edge of the desk 1, the fixing clip 41 of the fixing base 4 is inserted into the edge of the desk, and the fixing base 4 is fixed on the desk 1 by tightening the fixing bolt 42 of the fixing base 4.
The length of the telescopic plate 321 and the chute plate 322 in sliding fit is adjusted to adjust the length of the support plate 32 of the support connection mechanism 3, so as to adjust the height of the concave cylindrical mirror 2, so that the center position of the mirror surface 21 of the concave cylindrical mirror 2 reaches the height of the user with eyes 53 looking straight, and the adjusting lock 323 is screwed down to lock the height of the concave cylindrical mirror 2.
The connection angle of the torque hinge 31 is adjusted, the pitch angles of the concave cylindrical mirror 2 and the mirror surface 21 are changed accordingly, until the light 51 of the writing on the desk 1 which is incident on the mirror surface 21 of the concave cylindrical mirror 2 is reflected by the mirror surface 21, the reflected light 52 can reach the eyes 53 of the user, and the torque hinge 31 is self-maintained at the connection angle.
