Position step 3, the second desktop positioning step, the 3rd desktop positioning step recess downward.First Retractive leg in the present invention
It is provided between table seat for consolidating after the first desktop position adjustment to the Retractive leg that the first Retractive leg is fixed into row position
Determine structure, the first Retractive leg, the second Retractive leg and the 3rd Retractive leg are single leg structure, the second Retractive leg, the 3rd Retractive leg with
Between table seat and be not provided with table leg fixed structure, as desktop in use, by the location fits of corresponding two positioning steps,
Ensure the upper faces of three desktops at grade, while the second desktop, the 3rd desktop are also by the second desktop branch
Support positioning.
In the present embodiment, Retractive leg fixed structure include axis extend in left-right direction be used for hold out against the first Retractive leg
Top fastening screw 7,7 spinning of Top fastening screw is on table seat.Desk further includes upper end and the first Retractive leg is hinged and connected first is connected
Bar 8, the one end of head rod away from hinged end are provided with the spring catch that axis extends in left-right direction, and spring catch includes positioning
Pin 12 and the tension spring 13 being arranged between shop bolt and head rod, are provided with the first Retractive leg for and first connect
First Retractive leg location hole of the spring of the spring catch location fit on extension bar, head rod 8 when not in use, spring finger setting
It is plugged in the first Retractive leg location hole of the spring, head rod 8, which is located in, to be vertically arranged, and is provided with the second Retractive leg 19
The second Retractive leg spring catch location hole 9 being used for spring finger setting inserting that one row are distributed along the vertical direction.It is flexible first
The second connecting rod 10 is also hinged on leg, the second connecting rod 10 is identical with the structure of head rod, it is used for and the 3rd Retractive leg
On the 3rd Retractive leg spring catch location hole be connected, head rod, the second connecting rod are in the opposite sides of the first Retractive leg,
Table seat includes being used for realization the vertically extending guide ring 16 of the axis coordinated with the first Retractive leg guiding movement, guide ring
Notch 14 is avoided with vertically extending first for avoiding the head rod and for avoiding the second connecting rod
Vertically extending second avoids notch.As desk in use, head rod, the second connecting rod are all connected to
On one Retractive leg, as shown in Fig. 2, the first desktop rises to certain altitude, the second desktop and the 3rd desktop are just located in
Respective heights, hold out against fixation to the first Retractive leg by Top fastening screw, the adjustment of height of table top are achieved that, due to as desk
In use, the supporting power of desktop is little, therefore it is the achievable fixation to desktop by Top fastening screw；Used as stair
When, the first Retractive leg is still fixed by Top fastening screw, raises the second desktop, and the spring finger setting of head rod is plugged in the
On two Retractive legs in corresponding second Retractive leg spring catch location hole, the spring finger setting in the second connecting rod is plugged in the 3rd
On Retractive leg in corresponding spring catch location hole, the first Retractive leg and the second Retractive leg are connected into an entirety by head rod
First Retractive leg and the 3rd Retractive leg are connected into an overall structure by structure, the second connecting rod, when human body steps down in the first desktop
When on plate, by the power transmission of head rod and the second connecting rod, also carried between the second Retractive leg, the 3rd Retractive leg and table seat
The weight of human body, when human body is stepped down on the second desktop, is stretched by the power transmission of head rod and the second connecting rod, first
Also carry the weight of human body between contracting leg, the 3rd Retractive leg and table seat, therefore each Retractive leg can make single leg structure, have
Beneficial to making, whole desk is more compact, while each Retractive leg joint action, it is ensured that the safety in utilization of stair.
In other embodiments of the invention：It can also set and hold out against between second Retractive leg, the 3rd Retractive leg and table seat
Screw；Certain 3rd desktop and the 3rd Retractive leg can not also be set；Retractive leg fixed structure can also be bolt fastening structure
Either pipe clamp.
The embodiment 2 of desk is as shown in Figure 5：As different from Example 1, head rod 8, second connects embodiment 2
Bar 10 is length-adjustable telescopic advance lever, and telescopic advance lever includes two sections of spaced bodies of rod 81,83 and thread bush 82, spiral shell
Two sections of line set are equipped with oppositely oriented connection screw thread, and the abutting end of two sections of bodies of rod is connected with corresponding connection screw thread, passes through respectively
Thread bush 82 is rotated, the length of telescopic advance lever can be adjusted, so as to the spring catch location hole that spring catch insertion is specified
In, the requirement to desk installation accuracy on the one hand can be so reduced, in addition what is more important, can adjust the first connection
The angle of inclination of bar, the second connecting rod, because head rod, the angle of inclination of the second connecting rod are bigger（Closer to vertical shape
State）, the active force that two neighboring Retractive leg is undertaken is average, that is to say, that the inclination of head rod, the second connecting rod
Angle is bigger, and whole stair can carry more heavy weight people, and the crowd of different weight can select to use respectively.
