The left end passes through the left plate of the base 2 and extends to the outside of the base 2. The left end of the high-strength rotating cylinder 3 is fixedly connected with a rotationally adjustable side cap 17. The setting of the rotationally adjustable side cap 17 facilitates the rotation of the high-strength rotating cylinder 3. The surface of the high-strength rotating cylinder 3 is fixedly sleeved with a gear card rotating disk 8. The teeth of the gear card rotating disk 8 are sleeved and meshed with the tooth grooves of the displacement inner gear cylinder 9. The inner wall of the right side plate of the displacement inner gear cylinder 9 is slidably sleeved with the surface of the high-strength rotating cylinder 3. The right side of the displacement inner gear cylinder 9 is fixedly connected with a top shifting sleeve 10. The inner ring of the top shifting sleeve 10 is sleeved on the surface of the high-strength rotating cylinder 3. The surface of the top shifting sleeve 10 is slidably connected to the inner wall of the base 2. The right edge of the top shifting sleeve 10 is fixedly connected with a gasket 12. The right side of the gasket 12 A return spring 13 is fixedly connected to the side, and the right side of the return spring 13 is fixedly connected to the inner wall of the base 2. The inner ring of the return spring 13 is sleeved on the surface of the high-strength rotating cylinder 3. Through the setting of the return spring 13, the displacement inner gear cylinder 9 is continuously subjected to a pushing force to the left, so that the displacement inner gear cylinder 9 can stably engage with the gear card rotating disk 8 without being affected by force. Two positioning sliding rods 11 are fixedly connected to the right side of the displacement inner gear cylinder 9. The right side surface of the positioning sliding rod 11 is slidably connected to the inner wall of the base 2. The two positioning sliding rods 11 are symmetrically distributed in the upper and lower parts of the middle part of the displacement inner gear cylinder 9. Through the setting of the positioning sliding rod 11, the displacement inner gear cylinder 9 can be horizontally displaced. When the displacement inner gear cylinder 9 is in a state of being unable to rotate, a linkage slide 18 is fixedly connected to the top of the displacement inner gear cylinder 9, and the top of the linkage slide 18 is fixedly connected to the bottom of the push-press cylinder 14, and the surface of the push-press cylinder 14 is slidably connected to the inner wall of the base 2.

By setting the push-press cylinder 14 and the compression spring 15, the displacement inner gear cylinder 9 is driven to move synchronously by pushing the push-press cylinder 14, so as to achieve the effect of controlling whether the displacement inner gear cylinder 9 and the gear card rotating disk 8 are socketed and meshed.

[0024] When in use, the push-pull cylinder 14 is pressed to the right, and the displacement inner gear cylinder 9 is driven to press and displace horizontally to the right through the linkage slide 18, so that the displacement inner gear cylinder 9 is separated from the socket engagement of the gear clamp rotating disk 8, and then the rotation adjustment side cap 17 is rotated to drive the high-strength rotating cylinder 3 to rotate, so that it drives multiple swing support inclined pads 6 to rotate and swing synchronously to a suitable angle, and then the force of pressing and pushing the cylinder 14 is released. At this time, the compression spring 15 and the return spring 13 drive the displacement inner gear cylinder 9 to move horizontally to the left through the elastic return reaction force, so that the displacement inner gear cylinder 9 is re-sleeved and engaged with the gear clamp rotating disk 8, and the rotation angle of the high-strength rotating cylinder 3 is fixed. At the same time, the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0025] In summary, the adjustment device of the teaching computer keyboard, through the setting of the high-strength rotating cylinder 3, and the coordinated use of the synchronous anti-rotation block 5, the swing support inclined pad 6, the anti-skid bottom connecting pad 7, the gear card rotating disk 8, the displacement inner gear cylinder 9, the top displacement sleeve 10, the positioning sliding rod 11, the reset spring 13, the push cylinder 14, the compression spring 15, and the rotation adjustment side cap 17, plays a role in adjusting the displacement inner gear cylinder 9 through the horizontal displacement, regulating the displacement inner gear cylinder 9 and the gear card rotating disk 8 fixedly sleeved on the surface of the high-strength rotating cylinder 3.

The rod 11 slides and displaces inside the base 2 to position the direction of rotation of the internal gear cylinder 9, so that it can control the rotation of the adjustable gear card turntable 8 to achieve the controllable and adjustable rotation degree of the high-strength rotating cylinder 3, that is, the rotation of the high-strength rotating cylinder 3 drives the swing support inclined pad 6 to swing and tilt around the high-strength rotating cylinder 3, and the front bottom plate of the keyboard body 1 is tilted upward, so that it can be quickly and easily adjusted at any time according to the user's needs. The height of the tilt support at the front end of the keyboard body 1 is adjusted to facilitate smoother use.
