A use method of a multi-mode learning table for English teaching comprises the following steps:
s1: lifting height: firstly, a first hand twisting handle 108 is twisted, the worm 107 is driven to rotate by twisting the first hand twisting handle 108, the worm 107 drives a worm wheel 105 to rotate, the worm wheel 105 drives a driving rotating shaft 104 to rotate, the driving rotating shaft 104 drives a first driving gear 106 to rotate, the first driving gear 106 drives a first driven gear 103 positioned at the upper part of the right side to rotate, the first driven gear 103 positioned at the upper part of the right side drives other three first driven gears 103 through a first transmission toothed belt 109 which is meshed with the first driven gears 103, the four first driven gears 103 rotate to respectively drive four screw rods 404 to perform threaded motion, and the four screw rods 404 perform threaded motion in four third threaded grooves 403, so that four support columns 401 are driven to slide up and down in four sliding barrels 4, and the lifting effect is achieved;
s2: angle adjustment: screwing the second screwing handle 202, driving the first screw rod 2 to rotate by screwing the second screwing handle 202, driving the two second driving gears 205 to rotate by the rotation of the first screw rod 2, driving the two second driven gears 204 to rotate by the two second driving gear belts 209, driving the first rotating rod 203 to rotate by the two second driven gears 204, driving the connecting plate 201 to rotate by the rotation of the first rotating rod 203, adjusting the angle of the touch screen computer 206 by the rotation of the connecting plate 201, screwing the hand screwing screw head 507 after the touch screen computer 206 is adjusted to a proper angle by the second screwing handle 202, driving the second screw rod 506 to perform thread lifting movement in the fourth thread groove 508, screwing the second screw rod 506 to contact with the upper end of the pawl 502 to stop screwing, fixing the angle of the second groove 207 to prevent sliding, and limiting the lifting direction of the touch screen computer 206 by the arrangement of the ratchet 505 and the pawl 502, when the touch screen computer 206 needs to be placed back to the initial position, the hand-screw head 507 is screwed, the pressure of the second screw 506 on the pawl 502 is removed, the rotating handle 504 is rotated to drive the movable rod 501, the movable rod 501 drives the pawl 502, the engagement between the pawl 502 and the ratchet 505 is removed, the second hand-screw handle 202 can be rotated in the opposite direction, the touch screen computer 206 is adjusted back to the initial position, after the initial position is adjusted, the rotating handle 504 is released, the first return spring 503 can drive the pawl 502 and the rotating handle 504 to reset, and the engagement between the pawl 502 and the ratchet 505 is recovered.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the invention as defined by the appended claims. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
