When folded, the space occupied by the retracted second leg 3 can be reduced; when extended, the height of the tabletop can be adjusted simply by extending the second leg 3 to meet the user's needs.

[0024] In this embodiment of the invention, both the first leg 1 and the second leg 3 are tubular structures. The first leg 1 is larger than the second leg 3, allowing the second leg 3 to slide relative to the first leg 1. One end of the first leg 1 is connected to the tabletop. The tabletop is fixed by connecting the first leg 1 to the tabletop via four corners through the arrangement of at least four first legs 1. Alternatively, a bracket for fixing the tabletop can be connected to the first leg 1 first, and then the bracket can be used to connect to the tabletop. A snap-fit ​​button 2 is fixed to the side of the first leg 1 facing the second leg 3 using fasteners such as screws or bolts. The snap-fit ​​button 2 is connected to the first bracket via the housing 23. The fastener can be connected to the first leg 1 via the upper part of the snap-fit ​​button 2, so that the lower part of the snap-fit ​​button 2 extends beyond the first leg 1. The lower part has a button portion 21 and a snap-fit ​​portion 22 to connect with the second leg 3. The second leg 3 has at least one snap-fit ​​hole 31, and there can be one or more snap-fit ​​holes 31. The snap-fit ​​hole 31 can be used with the snap-fit ​​button 2 to fix the second leg 3 onto the first leg 1. In order to realize the multi-level adjustment function, the snap-fit ​​hole 31 is preferably multiple, so as to realize multi-level adjustment with the snap-fit ​​button 2, thereby meeting the user's needs for desktops of different heights.

[0025] In one embodiment, the snap-fit ​​button 2 includes a button portion 21, a snap-fit ​​portion 22, and a housing 23. The housing 23 is fixedly connected to the first support leg 1, and the housing 23 has a first snap-fit ​​groove 231. The first snap-fit ​​groove 231 is used for the button portion 21 to be embedded, and the button portion 21 can slide within the first snap-fit ​​groove 231. The button portion 21 has a second snap-fit ​​groove 232, which is used for the snap-fit ​​portion 22 to snap-fit ​​the button, and the button portion 21 can drive the snap-fit ​​portion 22 to move synchronously. The snap-fit ​​portion 22 cooperates with the snap-fit ​​hole 31 to fix the second support leg 3. The second snap-fit ​​groove 232 is coaxial with the snap-fit ​​hole 31. When the button portion 21 slides towards the first support leg 1 within the first snap-fit ​​groove 231, the button portion 21 drives the snap-fit ​​portion 22 to disengage from the snap-fit ​​hole 31, and the second support leg 3 can slide relative to the first support leg 1.

[0026] In this embodiment of the utility model, the snap-fit ​​button 2 includes a button part 21, a snap-fit ​​part 22, and a housing 23. The housing 23 is fixedly connected to the first support leg 1, specifically, the upper end of the housing 23 is connected to the upper end of the first support leg 1. The housing 23 has a first snap-fit ​​groove 231, the shape of which matches the shape of the hand-pressing part of the button part 21, so that the button part 21 is embedded in the first snap-fit ​​groove 231. The button part 21 can slide in the first snap-fit ​​groove 231 under the action of the user, thereby driving the snap-fit ​​part 22 connected to it to move, thereby realizing the snap-fit ​​and separation of the snap-fit ​​part 22 and the second support leg 3. Specifically, the connection between the latching part 22 and the button part 21 is achieved by the button part 21 having a second latching groove 232 for the latching part 22 to latch the member. The latching part 22 includes a circular base 222 and a first flange 221 on a first side and a second flange 223 on a second side of the base 222. The first side refers to the side facing the second leg 3, and the second side refers to the side facing the housing 23. The first connecting flange is used to latch into the second latching groove 232 and then latches into the latching hole 31. The button part 21 is connected to the latching part 22 in the direction away from the second leg 3. When the button part 21 is pressed by the user, it moves towards the second leg 3, which can drive the latching part 22 to move synchronously. That is, the button part 21 drives the latching part 22 away from the second leg 3, so that the latching part 22 disengages from the latching hole 31, and the second leg 3 can slide relative to the first leg 1, thereby realizing the storage or shifting of the second leg 3. An elastic element (not shown in the figure) is provided between the latching part 22 and the housing 23; when the button part 21 slides toward the first support leg 1, causing the latching part 22 to separate from the latching hole 31, the elastic element has the potential energy to reset the latching part 22; when the user releases the hand, and the latching part 22 and the latching hole 31 are coaxial, the elastic element can drive the latching part 22 to move toward the latching hole 31, so that the latching part 22 is engaged in the latching hole 31 to fix the second support leg 3. The elastic element is a spring. In order to achieve better connection of the elastic element, in one embodiment, the snap-fit ​​portion 22 is provided with a second flange 223 on the side facing the elastic element. The second flange 223 can be snapped on by the elastic element, thereby ensuring the stability of the position of the elastic element.

[0027] To ensure the stability of the latching portion 22 and the button portion 21, in one embodiment, the button portion 21 is provided with first limiting members 211 on both sides of the latching portion 22; the first limiting members 211 are used to prevent the latching portion 22 from disengaging from the second slot 232. The first limiting members 211 may be in the form of reinforcing ribs, provided on both sides of the button portion 21 located on the second flange 223, with a height similar to that of the base 222 of the latching portion 22, thereby limiting the left and right swaying that may occur during the pushing process of the latching portion 22.

Figures 1-6 ; In one embodiment, the second leg 3 is provided with a claw 32 on the side facing the first leg 1, and the claw 32 is engaged with the inner wall of the first leg 1.

[0029] In this embodiment of the utility model, a claw 32 is inserted into the side of the second leg 3 facing the first leg 1. The claw 32 includes multiple claws arranged in an arc shape. The maximum diameter of the claw 32 is greater than that of the second bracket, so that the claw 32 can be locked into the inner wall of the first leg 1, which makes the extension and retraction of the second leg 3 more stable and prevents wobbling, thereby affecting the user's experience.

[0030] To prevent the pawl 32 from rotating relative to the first support leg 1, in one embodiment, the second support leg 3 has a first limiting groove 34 formed on the side facing the pawl 32; a second limiting member 33 is provided on the side facing the second support leg 32, and the first limiting groove 34 is used for the second limiting member 33 to engage; the second limiting member 33 can be a protrusion connected to the pawl 32, and the protrusion engages in the first limiting groove 34. The protruding structure can prevent the pawl 32 from rotating relative to the first support leg 3, thereby ensuring the stability of the extension and retraction of the second support leg 3. Furthermore, a sliding groove can also be connected inside the first support leg 1 for the protrusion to slide and connect, thereby improving the stability of the lifting and lowering.

[0031] Furthermore, the second limiting member 33, in cooperation with the snap button 2, can limit the second leg 3, preventing it from detaching from the first leg 1 and affecting the user experience. Specifically, in one embodiment, a limiting step 35 is formed on the housing 23; the second limiting member 33 extends beyond the first limiting groove 34 and abuts against the limiting step 35. That is, when the second leg 3 moves to the point where it is about to detach from the first leg 1, the protrusion of the second limiting member 33 can abut against the limiting step 35 of the housing 23 fixedly connected to the first leg 1, thereby preventing the second leg 3 from detaching from the first leg 1.
