[0002] A general table is mainly fixed with a support frame under the tabletop, and a table leg is provided under the support frame. The support frame and table legs of a general table are set at a fixed height. Since the height of the table top is fixed, the height cannot be adjusted. , inconvenient to use
In some occasions, it is difficult for a table with a fixed height to meet the needs of different users. For example, in a classroom, a table with a constant height is difficult to meet the needs of all students because the students are of different heights; There is a big difference in the height of children, and the height of the table needs to be adjusted to achieve a balance

Embodiment Construction
[0017] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0018] Such as figure 1 , figure 2 and image 3 A link type mechanical lifting table shown includes a desktop 1, a base 2 and a lifting device.
[0019] The lifting device includes a pipe sleeve 3, a screw rod 5, and a first gear 9 and a second gear 10 that engage with each other in a vertical direction. The screw rod 5 is installed in the pipe sleeve 3 and the top end is connected to the desktop 1, and the bottom end of the pipe sleeve 3 is connected to the base 2. The first gear 9 is threadedly connected with the screw rod 5 through an internal thread and is installed above the pipe sleeve 3. An annular ring 8 is arranged above the first gear 9. The annular ring 8 is...
