The elastic member 313 is connected between the first connecting rod 3111 and the second connecting rod 3121, and is capable of providing an elastic force for the opposite movement of the first connecting rod 3111 and the second connecting rod 3121.

When the first and second connection arms 311 and 312 are operated toward each other, that is, the first and second connection bars 3111 and 3121 are moved toward each other, the elastic member 313 is compressed and generates an elastic force. After the user pulls the first and second hand levers 610 and 620 to bring the mounting plate 100 and the storage box 200 to the target height, the user may release the first and second hand levers 610 and 620. At this time, the elastic member 313 releases its stored elastic force to return to a natural state, i.e., an uncompressed state, and the user saves time and effort.

Alternatively, the resilient member 313 is a spring, which is inexpensive and easy to replace and install.

Optionally, the shelving unit further includes a first hand-held lever 610 and a second hand-held lever 620. Wherein the first hand-held bar 610 is disposed at both end portions of the first connecting bar 3111; the second hand lever 620 is provided at both ends of the second connection lever 3121 corresponding to the first hand lever 610.

In this way, the user can perform the opposite operation of the first connection arm 311 and the second connection arm 312 by holding the first hand-held lever 610 and the second hand-held lever 620 located at the same side and applying force. When the stopper mechanism 320 is switched to the extended position, the user can move the stopper 322 up and down along the first side of the elevation restricting plate 323 by applying an upward or downward force to the first and second hand levers 610 and 620.
