Embodiment 1

[0023] see Figure 1~2 , in an embodiment of the present invention, a portable correcting bracket for an English extracurricular reader includes a clamping part 10 for installing the reader. 10 have the same structure, which will not be repeated here, and also includes a correction unit for automatically adjusting the distance between the reader and the human body. The mounting plate 7, the belt transmission mechanism 6 and the driving assembly for driving the rotating shaft 4 to rotate, the upper surface of the first mounting plate 1 is rotatably mounted with the rotating shaft 4, in this embodiment, the rotating shaft 4 preferably communicates with the rotating shaft 4 through a bearing and a bearing seat The first mounting plate 1 is rotationally connected, and the drive assembly includes a stepping motor 2 and a gear pair 3. The stepping motor 2 is fixedly mounted on the upper surface of the first mounting plate 1, and the stepping motor 2 is driven and connected to the ro...

Embodiment 2

[0027] see image 3 The difference between this embodiment of the present invention and Embodiment 1 is that a tripod 22 is detachably connected to the bottom of the first mounting plate 1, which is convenient for placing the device on the ground for reading.

[0028]The working principle of the present invention is: adjust the distance between the clamping plate 20 and the upper surface of the first mounting plate 1 by rotating the internal thread sleeve 19, so that the clamping plate 20 and the first mounting plate 1 cooperate to clamp the edge of the table, which is convenient for reading. When the instrument 11 detects that the distance between the human body and the human body is less than the preset value, the driving assembly is started to work, the driving assembly drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the second mounting plate 21 to rotate, the second mounting plate 21 drives the mounting shaft 5 to revolve, and the mounting shaft 5. The t...
