In this embodiment, the first arm 300 is a rectangular frame, the second arm 301 is a single rod, and the second arm 301 is connected in a cross rotation manner at a middle position of the first arm 300. In other embodiments, the lifting arms 3 of the lifting assembly may be arranged in two groups, three groups, etc., and arranged along the width direction of the working platform 1.

In order to synchronize the movement of the two first sliding members 101 or to synchronize the movement of the upper ends of the first arms 300 and the second arms 301, in some embodiments, as shown in fig. 2, 4 and 7, the lifting table further comprises at least one set of synchronizing assemblies provided on the working platform 1 or/and the base 2, the synchronizing assemblies comprising a gear rotatably connected to the working platform 1 or the base 2 and two racks slidingly engaged on the working platform 1 or the base 2 along the sliding direction of the sliding members, the two racks being disposed in parallel on both sides of the gear and being in meshing transmission with the gear; the two racks are respectively connected with the two first sliding pieces 101 or the two second sliding pieces 201 and are used for keeping the two first sliding pieces 101 or the two second sliding pieces 201 to move synchronously; the synchronous component is arranged, when the working platform 1 is lifted relative to the base 2, the traction or restriction of the synchronous component can enable the two first sliding pieces 101 or/and the two second sliding pieces 201 to always keep synchronous movement, that is, the synchronous component enables the upper end and the lower end of the first support arm 300 or/and the upper end and the lower end of the second support arm 302 to move oppositely or reversely at the same time, so that not only the lifting stability of the working platform 1 can be ensured, but also the working platform 1 is ensured not to incline in the lifting or descending process, and always keeps a horizontal state.

In the foregoing embodiment, if the synchronization assembly is a group, the synchronization assembly may be disposed on the working platform 1 or the base 2, for example, on the working platform 1, because the second sliding members at the lower ends of the two arms are in a sliding fit relationship with the base, one end of the power element may be connected to the base, and the other end may be connected to the lifting arm, so as to limit the translational sliding between the base and the two second sliding members, or limit the translational sliding between the base by other self-locking mechanisms.

In this embodiment, in order to ensure the sliding stability of the upper ends of the two support arms and the lower ends of the two support arms and the self-locking of the working platform and the base relative to the lifting assembly, the synchronization assemblies are arranged in two groups and are respectively arranged on the working platform 1 and the base 2, as shown in fig. 2, 4 and 7, the synchronization assemblies comprise a first synchronization assembly 5 and a second synchronization assembly 6, wherein the first synchronization assembly 5 comprises a first gear 500 arranged between two first sliding parts 101 and rotatably connected with the working platform 1, and two first racks 501 which are in sliding fit on the working platform 1 and respectively connected with the two first sliding parts 101, and the two first racks 501 are meshed with the first gear 500 for transmission; the second synchronizing assembly 6 comprises a second gear 600 arranged between the two second sliding parts 201 and rotatably connected with the base 2, and two second racks 601 which are in sliding fit on the base 2 and are respectively connected with the two second sliding parts 201, wherein the two second racks 601 are meshed with the second gear 600 for transmission. Thus, when the working platform 1 ascends relative to the base 2, the first support arm 300 and the second support arm 301 drive the two first racks 501 to move oppositely, and simultaneously, the two second racks 601 are linked to move oppositely and close together; conversely, when the working platform 1 descends relative to the base 2, the first support arm 300 and the second support arm 301 drive the two first racks 501 to move oppositely, and simultaneously, the two second racks 601 are linked to move oppositely and spread; because the first synchronous component 5 and the second synchronous component 6 both adopt the meshing of racks and gears to enable the movement of the two first racks 501 and the movement of the two second racks 601 to be synchronous, not only can the lifting stability of the working platform 1 be ensured, but also the working platform 1 can not incline in the lifting or descending process, and the working platform is always kept in a horizontal state.

In some embodiments, in order to ensure that the translational motion of the first rack 501 and the second rack 601 is stable and always kept engaged with the gears, as shown in fig. 7 and 8, an upper base 502 is connected to the working platform 1, and the first gear 500 is rotatably connected in the upper base 502; the upper base 502 is provided with two first guide holes which are respectively positioned at two sides of the first gear 500 and are respectively penetrated by two first racks 501; and a lower base 602 is connected to the base 2, and the second gear 600 is rotatably connected to the lower base 602; the lower base 602 is provided with two second guide holes respectively positioned at two sides of the second gear 600 and respectively penetrated by the two second racks 601.

As is well known, when the first arm 300 and the second arm 301 of the lifting arm 3 perform differential scissors movements, the first slider 101 and the second slider 201 connected to the first arm 300 and the second arm 301 perform translational movements while rotating circumferentially around their axes by an angle; therefore, in the present embodiment, as shown in fig. 2, 4, 7, 8 and 9, the outer ends of the two first racks 501 are respectively formed with first connecting seats 503, and the two first connecting seats 503 are respectively rotatably connected and axially limited on the two first sliding members 101; the outer ends of the two second racks 601 are respectively formed with a second connecting seat 603, and the two second connecting seats 603 are respectively rotatably connected and axially limited on the two second sliding pieces 201. Specifically, the two first sliding parts 101 are respectively provided with a first annular limiting groove 102 which corresponds to the two first connecting seats 503 and is concave inwards; each first connecting seat 503 is connected with a first elastic limiting block 504, and the first elastic limiting blocks 504 are embedded in the first annular limiting grooves 102; the two second sliding parts 201 are respectively provided with a second annular limiting groove 202 which corresponds to the two second connecting seats 603 and is concave inwards; each second connecting seat 603 is connected with a second elastic limiting block 604, and the second elastic limiting blocks 604 are embedded in the second annular limiting grooves 202. The elastic limiting block is embedded in the annular limiting groove to realize axial limiting between the connecting seat and the sliding piece. Thereby making the synchronicity of the first synchronization component 5 and the second synchronization component 6 more stable.

In the above embodiment, the first synchronization assembly 5 and the second synchronization assembly 6 have the same structure and are symmetrically arranged with respect to the height center of the lifting table; likewise, the dimensions of the first synchronizing assembly 5 and the second synchronizing assembly 6 can be adjusted to accommodate the synchronized movement of the two first slides 101 and the two second slides 201, depending on the height position of the central rotational axis of the lifting arm 3.

In some embodiments, to facilitate placement of the keyboard, a keyboard support is connected to a side of the working platform 1 close to the user, and a support pad is connected to the bottom of the keyboard support, where the bottom plane of the support pad is at the same level as the bottom plane of the base 2 when the working platform 1 is at the lowest position. Therefore, when the working platform 1 is at the lowest position, the supporting pad at the bottom of the keyboard tray is contacted with the ground or the table surface, so that the standing stability of the lifting working table is better.
