In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0048] The technical scheme of the utility model is further illustrated below by specific embodiments in conjunction with the drawings.

[0049] As shown in Figures 1 to 7 The utility model discloses a desktop rotation adjusting structure, including installation part 1, table board 2 and at least one adjusting assembly, installation part 1 sets up on the crossbeam 100 of table, table board 2 is rotatably connected on installation part 1, installation part 1 with table board 2 one is seted with first tooth shape groove 11, and the other is seted with second tooth shape groove 21, adjusting assembly includes movable gear 3, elastic part 4 and button 5, movable gear 3 is along the horizontal direction position and is adjustably worn in first tooth shape groove 11 and second tooth shape groove 21, movable gear 3 includes tooth disc part 31, and tooth disc part 31 is set with a plurality of first meshing part 32 and a plurality of second meshing part 33 along the circumference, elastic part 4 is abutted between first tooth shape groove 11 and tooth disc part 31, and button 5 is worn in the groove bottom of second tooth shape groove 21 and is abutted on tooth disc part 31. One side of one of first meshing part 32 and second meshing part 33 close to second tooth shape groove 21 is provided with guide inclined plane 330, and guide inclined plane 330 is obtusely arranged with one side of the other.

[0050] Specific to the embodiment, installation part 1 is set with first tooth shape groove 11, and table board 2 is set with second tooth shape groove 21, and guide inclined plane 330 is arranged on second meshing part 33, and guide inclined plane 330 is obtusely arranged with one side of first meshing part 32. Button 5 is worn on table board 2 and is abutted on tooth disc part 31.

[0051] Or, in other embodiments, the first tooth-shaped groove 11 can also be opened on the table board 2, the second tooth-shaped groove 21 is opened on the mounting part 1, and the button 5 is correspondingly arranged on the mounting part 1 and abuts against the toothed disc part 31. The guide slope 330 is still arranged on one side of the first engaging part 32 and the second engaging part 33 close to one of the second tooth-shaped grooves 21, that is, the guide slope 330 is arranged on the first engaging part 32 as shown, and the guide slope 330 is arranged at an obtuse angle with one side of the second engaging part 33. Figure 1

[0052] The movable gear 3 has a first state and a second state. In the first state, the first engaging part 32 is engaged with the first tooth-shaped groove 11, and the second engaging part 33 is engaged with the second tooth-shaped groove 21. At this time, the table board 2 can be rotated in the first direction. Specifically, when the table board 2 is rotated, the second tooth-shaped groove 21 abuts against the guide slope 330. Under the guidance of the guide slope 330, the rotating force acting on the table board 2 can be decomposed into a component force in the direction of the axis of the movable gear 3. Under the action of the component force, the movable gear 3 moves towards the first tooth-shaped groove 11, compresses the elastic member 4, and makes the second engaging part 33 disengage from the second tooth-shaped groove 21. Thus, the table board 2 can be rotated in the first direction by a certain angle, which is the angle corresponding to one second engaging part 33 in this embodiment. Then, the elastic member 4 restores the elastic deformation, and the movable gear 3 moves towards the second tooth-shaped groove 21 under the action of the elastic force. The second engaging part 33 is engaged with the second tooth-shaped groove 21 again, and the table board 2 is stably fixed to the mounting part 1. In the second state, the movable gear 3 is entirely located in the first tooth-shaped groove 11, and the table board 2 can be rotated in the second direction, which is opposite to the first direction. Specifically, in this embodiment, when the movable gear 3 is in the first state, the user can lift the table board 2 to adjust the angle of the table board 2. When the user needs to rotate the table board 2 downward, the button 5 needs to be pressed to push the movable gear 3 entirely into the first tooth-shaped groove 11, so that the table board 2 can be rotated. When the table board 2 is adjusted to the desired angle, the button 5 is released, and the movable gear 3 is automatically reset to the first state under the action of the elastic force of the elastic member 4. The above arrangement facilitates the accurate multi-angle adjustment of the table board 2, is convenient and fast to operate, and can also ensure the stability of the table board 2 during use, effectively avoiding the loose rotation of the table board 2.

[0053] Or, in other embodiments, the position of the guide slope 330 in the above-mentioned figure can be changed to be arranged on the other side of the second engaging part 33, so as to change the direction in which the table board 2 is freely rotated without pressing the button 5. Figure 1
