[0035] By means of the above mechanism: through the cooperation between the supporting legs 3 and the table legs 2, it is convenient to support the table top 4, the positioning mechanism is used to conveniently drive the plug board 10 to move, the supporting legs 3 are conveniently fixed by the plug board 10 so as to adjust the height of the table top 4, and the plug board 10 is fixed by the limiting mechanism to prevent the plug board 10 from being moved due to accidental touch.

[0036] As a preferred solution of the utility model, the positioning mechanism includes: two pull rings 6, two pull rods 7, two reset plates 8 and four reset springs 9; the two reset plates 8 are slidably connected to the inner wall of the corresponding fixed box 5, and the sides of the two reset plates 8 close to each other are respectively fixedly connected to the sides of the two plug plates 10 away from each other, the two pull rods 7 are respectively fixedly connected to the sides of the two reset plates 8 away from each other, and the sides of the two pull rods 7 away from each other extend to the outside of the corresponding fixed box 5, the two pull rings 6 are respectively fixedly connected to the sides of the two pull rods 7 away from each other, and the pull rods 7 can be pulled by moving the pull rings 6, and the pull rods 7 can drive the reset plate 8 and the plug plate 10 to move horizontally. When the reset plate 8 moves horizontally, the reset spring 9 will be compressed. At this time, the plug plate 10 moves horizontally and disengages from the slot to unlock the support leg 3.

[0037] As a preferred solution of the utility model, the limiting mechanism includes: two push plates 12 and two unlocking rods 13; the two push plates 12 are respectively slidably connected to the sides of the two fixed boxes 5 away from each other, the two unlocking rods 13 are respectively rotationally connected to the sides of the two push plates 12 away from each other, the sides of the two clamping blocks 15 away from each other are respectively rotationally connected to the sides of the two unlocking rods 13 close to each other, and the bottoms of the two pull rods 7 are symmetrically provided with clamping grooves, the number of the clamping grooves is four, and the two clamping blocks 15 are engaged with the corresponding clamping grooves.

[0038] As a preferred solution of the utility model, the two fixed boxes 5 are fixedly connected to the sides away from each other with support frames 11, the tops of the two support frames 11 are slidably connected to the bottoms of the corresponding push plates 12, and the two support frames 11 pass through the corresponding push plates 12. The movement of the push plates 12 will push the unlocking rod 13, and the movement of the unlocking rod 13 will push the card block 15 downward. When the card block 15 moves, it will break away from the card slot to unlock the pull rod 7.

[0039] As a preferred solution of the utility model, the tops of the two support frames 11 are fixedly connected to the limiting sleeves, the outer walls of the two clamping blocks 15 are slidably connected to the inner walls of the corresponding limiting sleeves, the bottom inner walls of the two limiting sleeves are fixedly connected to the positioning springs 16, and the tops of the two positioning springs 16 are fixedly connected to the bottoms of the corresponding clamping blocks 15.

The elastic force of the push springs 14 facilitates the push plates 12 to move forward and reset.

[0041] The working principle of the utility model is as follows: in actual use, the base 1 is placed in a suitable position for the use of the table board 4. When the height of the table board 4 needs to be adjusted, the push plate 12 is first pushed backward. When the push plate 12 moves, the push spring 14 is compressed. At this time, the movement of the push plate 12 will push the unlocking rod 13, and the movement of the unlocking rod 13 will push the card block 15 to move down. When the card block 15 moves, the positioning spring 16 is compressed. At this time, the card block 15 moves down and disengages from the card slot to unlock the pull rod 7. At this time, the pull ring 6 can be pulled, and the pull rod 7 can be pulled by moving the pull ring 6. The pull rod 7 can drive the reset plate 8 and the plug plate 10 to move horizontally. When the reset plate 8 moves horizontally, the reset spring 9 will be compressed. At this time, the plug plate 10 moves horizontally and disengages from the slot to unlock the support leg 3. At this time, the push plate 1 is released. 2. The pushing spring 14 pushes the push plate 12 to move forward and reset. At the same time, the positioning spring 16 pushes the card block 15 to move up and engage with the card slot to fix the pull rod 7, so that the supporting leg 3 remains unlocked. At this time, the table board 4 can be pushed to move up and down. The movement of the table board 4 can drive the supporting leg 3 to move up and down. When the table board 4 moves to a suitable height, the card block 15 is pushed down to unlock the pull rod 7 by pushing the push plate 12. At this time, the reset spring 9 loses its restriction and pushes the reset plate 8 to move horizontally. The reset plate 8 moves horizontally and drives the pull ring 6 and the plug plate 10 to move horizontally and reset. At this time, the plug plate 10 engages with the slot to fix the supporting leg 3. At this time, the push plate 12 is released, and the card block 15 is reset to keep the plug plate 10 stable when the pull rod 7 is fixed, thereby achieving the effect of adjusting the height of the table board 4 according to usage requirements for use.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
