[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figures 1 to 10 A portable interactive teaching machine includes a main body 10, two vertical plates 2, a horizontal plate 3, and a movable plate 4. The two vertical plates 2 are mounted on the movable plate 4, and the bottom of the movable plate 4 is provided with several movable casters 401. The horizontal plate 3 is positioned between the two vertical plates 2. The main body 10 is connected to a round rod 2. Each of the two vertical plates 2 is provided with an inner cavity 201, a through groove 202, and several slots 203. The inner cavity 201 has a groove 202 on one side wall and several slots 203 on each side wall. The machine also includes:

[0024] The support device includes a circular grip 5, a first slide bar 6, a second slide bar 7, two sliders 8, a fixing device, and four locking blocks 9 and a first buffer device. The circular grip bar 5 has two T-shaped connectors 501, which are connected to the main body 10 of the teaching all-in-one machine. The first slide bar 6 and the second slide bar 7 are each located at one end of the circular grip bar 5. The slider 8 is slidably connected to the inner cavity 201. The slider 8 has a through circular hole 801. The first slide bar 6 and the second slide bar 7 are slidably connected to the circular hole 801 and can rotate relative to it. The two locking blocks 9 and the two second buffer devices are all located on the slider 8. The locking blocks 9 can slide relative to the slider 8 and one end of them extends into the circular hole 801. The first slide bar 6 and the second slide bar 7 each have two triangular cuts. The fixing device is used to fix the circular grip bar 5 so that it cannot rotate. In this invention, the initial position of the first slide rod 6 is such that one end abuts against one side wall of the inner cavity 201 on a vertical plate 2. One end of the second slide rod 7 is inside the circular hole 801 of a slider 8 and does not contact one side wall of the inner cavity 201 on another vertical plate 2. One end of the locking block 9 is originally engaged with the locking block 9, and the other end contacts the inclined wall of the cut. The first buffer device is in a compressed state, supporting the slider 8 and thus fixing the circular grip 5 between the two vertical plates 2. When it is necessary to adjust the height of the teaching all-in-one machine body 10, the circular grip 5 is moved to drive the second slide rod 7 to move within the circular hole 801 until one end of the second slide rod 7 contacts one side wall of the inner cavity 201 on the vertical plate 2. The positions of the triangular cuts on the first slide rod 6 and the second slide rod 7 also change. One end of the locking block 9 does not contact the inclined wall of the cut. The first buffer device applies force to the locking block 9 to make it move towards the wall. The slider 8 moves internally out of the slot 203. Without support, the slider 8 can slide up and down in the inner cavity 201. After the slider 8 is moved to the approximate position, the circular handle 5 moves in the opposite direction. One end of the locking block 9 contacts the inclined wall of the cut. The locking block 9 will slowly move outward on the slider 8 until one end engages with the slot 203, thereby fixing the adjusted circular handle 5. This replaces the traditional method of adjusting the lifting device and then fixing it with bolts. One person can operate it. When the teaching all-in-one machine body 10 is not in use, in order to prevent the screen of the teaching all-in-one machine body 10 from being damaged by impact, the circular handle 5 is moved to make the locking block 9 disengage from the slot 203. The fixing device does not work. The circular handle 5 can rotate to make the teaching all-in-one machine body 10 rotate 90° to be parallel to the ground. The slider 8 moves downward until the screen of the teaching all-in-one machine body 10 contacts the top of the horizontal plate 3, which plays a role in protecting the screen of the teaching all-in-one machine body 10. Specifically, one end of the connector 501 is connected to the outer shell of the teaching all-in-one machine body 10 by bolts; the slider 8 is fitted to the wall of the inner cavity 201; the first slide rod 6 and the second slide rod 7 are both circular slide rods; the first slide rod 6 and the second slide rod 7 can slide up and down in the slide groove 202; the bottom of the horizontal plate 3 is provided with several support rods, and the support rods are connected to the movable plate 4.

[0025] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0026] In this embodiment, the surface of the card block 9 that contacts the inclined wall of the cut is an inclined surface.

[0027] In this embodiment, the slider 8 is provided with two T-shaped grooves 802 communicating with the circular hole 801; the first buffer device includes two ear plates 11 and a first spring 12. The locking block 9 is provided with ear plates 11 on both sides. The first spring 12 is located between one side of the ear plate 11 and the wall of the T-shaped groove 802. When the first slide rod 6 and the second slide rod 7 move to the right with the circular grip rod 5, the ear plate 11 will be subjected to the force of the first spring 12, causing the locking block 9 to move into the slider 8 until one end of it disengages from the locking groove 203 and moves into the locking groove 203. The slider 8 can move up and down in the inner cavity 201. When the first slide rod 6 and the second slide rod 7 move to the left, the inclined wall of the cut will exert a pushing force on one end of the locking block 9, causing one end to slowly move outward on the slider 8 and cooperate with the locking groove 203. At the same time, the ear plate 11 squeezes the first spring 12.

[0028] In this embodiment, both ends of the circular grip 5 are provided with elongated grooves 502; the fixing device includes a second buffer device, two locking plates 13, and support plates 14 of different lengths. The support plate 14 is provided with a through groove 141, and one end of the support plate 14 is mounted on the slider 8. One end of the locking plate 13 is rotatably mounted in the through groove 141, and the other end cooperates with the elongated groove 502. The second buffer device is located between the circular grip 5 and the second sliding rod 7. The first sliding rod 6 and the second sliding rod 7 move to the right with the circular grip 5. One end of the second slide rod 7 contacts one side wall of the inner cavity 201, the locking block 9 disengages from the already locked slot 203, the locking plate 13 does not disengage from the long slot 502, and the circular grip rod 5 cannot rotate. When the circular grip rod 5 is pushed to the right, the second buffer device is compressed, and the circular grip rod 5 drives the first slide rod 6 to continue moving to the right. The second slide rod 7 remains stationary, and the locking plate 13 rotates under the pushing force. When the locking plate 13 disengages from the long slot 502, the circular grip rod 5 can rotate, and the main body 10 of the teaching all-in-one machine is rotated 90°. With the ground parallel, after the pushing force of the circular grip 5 disappears, the second buffer device applies a reaction force to the circular grip 5, pushing it to the left. The second slide bar 7 remains stationary, and the locking block 9 is still disengaged from the slot 203. The slider 8 moves downward until the screen of the interactive whiteboard 10 contacts the top of the horizontal plate 3, preventing objects from hitting the screen of the interactive whiteboard 10. When the interactive whiteboard 10 needs to be used, the circular grip 5 is given an upward force, and the slider 8 moves upward to approximately the required height. Then, the circular grip 5 is rotated so that the screen of the interactive whiteboard 10 is perpendicular to the ground. The locking plate 13 rotates in the opposite direction under the action of gravity, returning to the long slot 502 to prevent the circular grip 5 from rotating. Then, the circular grip 5 is given a reverse force to move the first slide bar 6 and the second slide bar 7 to the left until one end of the first slide bar 6 abuts against one side wall of the inner cavity 201 on a vertical plate 2. The locking block 9 is moved by the inclined wall of the cut on the first slide bar 6 and the second slide bar 7 until it engages with the slot 203, thereby fixing the slider 8. Specifically, the support plate 14 can slide up and down within the groove 202.

[0029] In this embodiment, the second buffer device includes an outer tube 15, a second spring 16, and a T-shaped slide bar 17. The outer tube 15 is mounted on the circular grip 5, and one end of the T-shaped slide bar 17 can slide within the outer tube 15. The second spring 16 is positioned between the circular grip 5 and the T-shaped slide bar 17. When the circular grip 5 needs to rotate, a rightward push is applied to it, causing it to move to the right and thus moving the outer tube 15 and the second spring 16. Since the T-shaped slide bar 17 does not move, the second spring 16 contracts under the pushing force, causing the locking plate 13 to disengage from the long groove 502, allowing the circular grip 5 to rotate. The long groove 502 also rotates accordingly. When the rightward push on the circular grip 5 disappears, the second spring 16 applies a reaction force to the circular grip 5, causing it to move to the left. When the circular grip 5 is rotated in the opposite direction, the long groove 502 returns to its original position, and one end of the locking plate 13 rotates into the long groove 502 under the influence of gravity, preventing the circular grip 5 from rotating. Specifically, the second buffer device can slide up and down within the slide groove 202.

[0030] In this embodiment, the vertical plate 2 is provided with a clearance groove 204, which is set on one side wall of the inner cavity 201; one end of the second slide rod 7 is provided with two mutually perpendicular insertion holes 701 and two slots 702, and the insertion holes 701 and slots 702 communicate with each other; one of the sliders 8 is provided with a through U-shaped groove 803, which communicates with the round hole 801; it also includes a frustum-shaped insertion rod 18, which is provided with a protrusion on one side, and the protrusion is connected to the wall of the inner cavity 201. When adjusting the height and angle of the teaching all-in-one machine body 10, the locking block 9 needs to disengage from the locking slot 203. The slider 8 is not supported. When the person does not hold the round grip rod 5, the slider 8 will move downward. After the insertion rod 18 is inserted into the insertion hole 701, the slider 8 cannot continue to move downward, which plays a protective role. When the screen of the interactive whiteboard 10 needs to be in contact with the horizontal plate 3, the circular grip 5 moves to the left until one end of the first slide bar 6 is in contact with one side wall of the inner cavity 201 on the vertical plate 2. The frustum-shaped part of the insert rod 18 disengages from the slot 702. The locking block 9 moves outward from the slider 8 until one end moves to the clearance slot 204. Holding the circular grip 5, move downward until the screen of the interactive whiteboard 10 is in contact with the horizontal plate 3. When the interactive whiteboard 10 needs to be in contact with the horizontal plate 3, hold the circular grip 5 and move upward a certain distance. Then, the circular grip 5 moves to the right so that one end of the locking block 9 moves into the slider 8 away from the clearance slot 204. When it moves upward to the approximate desired position, the circular grip 5 moves to the left and the locking block 9 moves outward to cooperate with the locking slot 203 to fix the slider 8.
