The mounting seat 1 is supported by a supporting mechanism composed of the supporting tube 2 and the connecting slide bar 3, and the installation height value of the training blackboard 11 is adjusted by controlling the connecting slide bar 3 to slide inside the supporting tube 2, and the stability during placement is improved by the non-slip pad arranged at the bottom of the mounting base 21.

[0028] Please refer again Figure 1 , Figure 3 and Figure 4 , a driving tooth 31 is provided on the connecting slide rod 3, and a driving gear 4 is rotatably connected inside the supporting tube 2, and the driving gear 4 meshes with the driving tooth 31. There are two driving gears 4, and the two driving gears 4 are fixedly connected by a connecting rotating rod 5. One end of the mounting seat 1 is fixedly connected to a storage box 12, and the interior of the storage box 12 is fixedly connected to a partition. One end of the connecting rotating rod 5 is fixedly connected to a hand wheel, and the hand wheel at one end of the connecting rotating rod 5 is rotated to drive the two driving gears 4 to rotate inside the two supporting tubes 2, and the connecting slide rod 3 is driven to lift and slide on the top of the supporting tube 2 under the meshing action with the driving tooth 31, so as to adjust the installation height value of the training blackboard 11.

[0029] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 5The two support tubes 2 are fixedly connected with a connecting frame 6, and a limiting mechanism for limiting the reverse rotation of the connecting rotating rod 5 is provided on the connecting frame 6. The limiting mechanism includes a movable plug rod 61 sliding on the connecting frame 6, and a limiting ratchet 51 is fixedly connected to the connecting rotating rod 5. One end of the movable plug rod 61 is arranged between the teeth of the limiting ratchet 51. When the connecting rotating rod 5 rotates, the inclined surface of the movable plug rod 61 is squeezed by the inclined surface of the limiting ratchet 51, thereby pushing the movable plug rod 61 to slide backward. When rotating in the reverse direction, the plane of the limiting ratchet 51 conflicts with the plane of the movable plug rod 61, thereby limiting the reverse rotation of the connecting rotating rod 5, so that the connecting sliding rod 3 can only rise. One end of the movable plug rod 61 is inclined, and one side of the movable plug rod 61 is fixedly connected with a connecting plate 62. The connecting plate 62 and the connecting frame 6 are connected by a spring. Under the action of the provided connecting plate 62 and the spring, the movable plug rod 61 is quickly slid and reset without force to form a ratchet mechanism.

[0030] Please refer again Figure 1 and Figure 3 A sliding frame 7 is slidably connected to the training blackboard 11, and a wiping pad 9 for cleaning the training blackboard 11 is fixedly connected to the inner wall of the sliding frame 7. A lighting lamp 8 is fixedly connected to the sliding frame 7. A reciprocating screw rod 71 is rotatably connected between the mounting seat 1 and the training blackboard 11. The sliding frame 7 is threadedly connected to the reciprocating screw rod 71, and a driving motor 72 is fixedly connected to the bottom of the mounting seat 1. The output shaft end of the driving motor 72 is fixedly connected to the reciprocating screw rod 71. The reciprocating screw rod 71 is driven to rotate by starting the driving motor 72, so that the sliding frame 7 is lifted and reciprocated on the training blackboard 11, and the surface of the training blackboard 11 is scrubbed by the wiping pad 9.

[0031] Working principle: After installing the device at a suitable position, the training content is written and displayed through the training blackboard 11. The hand wheel at one end of the connecting rotating rod 5 is turned to drive the driving gear 4 to rotate inside the supporting tube 2. The driving gear 4 is meshed with the driving teeth 31 to drive the connecting slide rod 3 to slide and rise to adjust the installation height value of the training blackboard 11. When the connecting rotating rod 5 rotates, the inclined surface of the movable plug rod 61 is squeezed by limiting the inclined surface of the ratchet 51, thereby pushing the movable plug rod 61 to slide backward. When rotating in the reverse direction, the plane of the limiting ratchet 51 conflicts with the plane of the movable plug rod 61, thereby limiting the reverse rotation of the connecting rotating rod 5. The connecting slide rod 3 can only rise. When the training blackboard 11 needs to be adjusted to descend, one end of the movable plug rod 61 is pulled out from the teeth of the limiting ratchet 51 by pulling one end of the connecting plate 62, so that the connecting rotating rod 5 can slide freely, thereby adjusting the descent of the training blackboard 11. When the training blackboard 11 needs to be scrubbed, the reciprocating screw rod 71 is driven to rotate by starting the driving motor 72, and the sliding frame 7 is driven to reciprocate and slide on the training blackboard 11. The training blackboard 11 is scrubbed by the wiping pad 9. The storage box 12 is provided for easy storage of some daily writing tools, and the lighting lamp 8 is provided to illuminate the training blackboard 11.
