When the wrench 130 is released, the wrench 130 returns to the locked position, and the buckle 421 is engaged with the hook 134 to achieve the locking state in the stored state. When it is necessary to raise the height of the lifting table, the wrench 130 is rotated upward to the unlocking position, the jam between the buckle 421 and the hook 134 is released, and the self-locking function of the auxiliary power member 150 is released, and the torsion springs 212 and 222 are Under the action, the top angle α between the first support assembly 200 and the second support assembly 300 is reduced, and the overall height of the lifting table is raised to meet the stance requirement, and the wrench 130 is loosened.

Figures 8-14 illustrate, from various angles, the entirety of a support structure and various components or portions included in the support structure in accordance with another embodiment of the present invention. The main difference between this embodiment and the embodiment depicted in Figures 1-7 is the top connection assembly 100', and thus the same or similar components as the above-described embodiments will be described with the same reference numerals when describing the other embodiment, and These same or similar components will not be described in detail.

The top connection assembly 100' includes a stationary assembly and a moving assembly 110'. The moving assembly 110' is movable relative to the stationary assembly in a first horizontal direction. The first horizontal direction is the longitudinal direction of the lift table shown by the arrow A in FIG. In the embodiment shown in the figures, the securing assembly is separate and includes a first securing assembly 120' and a second securing assembly 140' spaced apart in a first horizontal direction.

Preferably, the first fixing member 120' includes a pair of first fixing members 122' disposed opposite to each other, and a pair of second fixing members 124' disposed opposite to each other, as shown in Figs. The opposite inner side of the first fixing member 122' is provided with a first slide 126', and the opposite inner side of the second fixing member 124' is provided with a second slide 128'. The moving assembly 110' has a Y-shape, and the Y-shaped moving assembly 110' has a large-sized end and a small-sized end along the first horizontal direction. A first slider 112' is disposed on both sides of the large-sized end of the moving assembly 110', and a second slider 114' is disposed on both sides of the small-sized end of the moving assembly 110'. The first slider 112' is slidably coupled to the first runner 126' and the second slider 114' is slidably coupled to the second runner 128'. The first slider 112' and the second slider 114' may be pulleys, projections, and the like. Preferably, the first slider 112' and the second slider 114' are convex to simplify the structure and reduce the thickness of the lift table in the stowed state. The above scheme using the Y-shaped moving assembly 110' can alleviate the weight of the support structure, and since the sliders are both disposed at the end of the moving assembly 110', the spacing between the first slider 112' and the second slider 114' Larger, so the movement of the moving assembly 110' can be made more stable.

Further preferably, as shown in Figures 8-14, the lock switch has a preferred configuration, the lock switch including a wrench mount 131', a wrench 130', a transmission member 132', and a pivot member 135'.

The wrench holder 131' is disposed at the end of the fixing assembly along the first horizontal direction, and the first end of the auxiliary power member 150 is fixed to the wrench holder 131' as shown in FIG. The wrench 130' is pivotally disposed within the wrench mount 131' between the locked position and the unlocked position. The transmission member 132' is coupled to the wrench 130' and is moved by the wrench 130' in a first horizontal direction. One end of the pivoting member 135' is pivotally coupled to the wrench mount 131', and the other end can push the first end of the auxiliary power member 150 under the pushing of the transmission member 132' to unlock the auxiliary power member 150. Since the pivoting member 135' increases the force arm of the ejector auxiliary power member 150, the user can rotate the wrench with a small force, thereby having a good hand feeling and improving the user experience.

The transmission member 132' can be sandwiched between the table top and the wrench holder 131', and the wrench holder 131' is restricted from being oriented in a first horizontal direction within a certain range. Illustratively, the protrusion 134a' on the transmission member 132' for pushing the pivoting member 135' protrudes below the wrench holder 131', and the remaining portion may be held between the table top and the wrench holder 131'.

The hook 134' is disposed below the transmission member 132'. The hook 134' is engageable to the bottom frame assembly when the wrench 130' is in the locked position and can be disengaged from the bottom frame assembly when the wrench 130' is in the unlocked position. The function of this portion of the hook 134' is the same as that of the foregoing embodiment, and therefore will not be described again.

For the above exemplary embodiment, when it is required to lower the height of the lifting table, the palm presses the table and the finger pulls the wrench 130' to rotate the wrench 130' upward to the unlocking position. Referring to FIG. 14, the transmission member 132' moves to the left side. The protrusion 134a' thereon pushes the pivoting member 135' such that the pivoting member 135' pushes the first end of the pivoting member 135' (for example, the ejector pin on the self-locking gas spring), releasing the auxiliary power member 150 Self-locking function.
