One end of column 1 is in contact with the outside of turntable 4, by column 1, U-shaped shielded frame 2, clipboard 3, turntable 4, rotation hole 5,
Shaft 6, disk 7, screw rod 8, support rod 9, thread groove 10, screw rod 11, bolt hole 12 and shaft hole 13 match, due to support rod
9 are set as cylindrical structure, and the bottom side of support rod 9 and the bottom of turntable 4 are on same level axis, when turntable 4 is placed
When on floor, the bottom side of multiple support rods 9 can be contacted with floor, one end and turntable due to support rod 9 close to column 1
4 outside is in contact, and turntable 4 can limit the position of support rod 9, support rod 9 is avoided to be folded upward at, at this time multiple support rods 9
Can common column 1 be supported, can be erected at what clipboard 3 consolidated on floor, when needing to split whole device
When transport, turn support rod 9 rotates support rod 9 on screw rod 8, due to being threadedly coupled between support rod 9 and screw rod 8, makes
Support rod 9 is separated close to one end of column 1 with turntable 4, pushes up support rod 9, and support rod 9 drives disk 7 to exist by screw rod 8
The outside of shaft 6 rotates, and vertical state when support rod 9 is rotated, opposite direction turn support rod 9 makes support rod 9 in screw rod 8
Outside moves down, and the bottom end of support rod 9 can be in contact with the top of turntable 4, multiple support rods 9 can be accommodated in turntable
It 4 top can be by U-shaped shielded frame 2 since turntable 4 and U-shaped shielded frame 2 are attached by screw rod 11 with column 1
It is disassembled from column 1 with turntable 4, realizes to the fractured operation of whole device, reduce the occupied space of whole device, this reality
Reasonable with new design, structure is simple, easy to operate, the erection that clipboard 3 consolidates can be got up, and convenient for whole device
Deconsolidation process is carried out, the occupied space of device is reduced, consequently facilitating transported and stored, it is more practical.
In the utility model, support rod 9 offers thread groove 10 close to the side of column 1, screw rod 8 and corresponding thread groove
10 are threadedly coupled, and the side of disk 7 offers shaft hole 13, and shaft 6 is rotatablely connected with corresponding shaft hole 13, the top of column 1
End and bottom end are welded with screw rod 11, and the bottom side of U-shaped shielded frame 2 and the top of turntable 4 offer bolt hole 12, screw rod 11
It is threadedly coupled with corresponding bolt hole 12, support rod 9 is cylindrical structure, and the bottom side of support rod 9 and the bottom of turntable 4 are in same
On one horizontal axis, the quantity of rotation hole 5 is three to five, and the equidistant interval setting in a ring of three to five rotation holes 5, is led to
Cross column 1, U-shaped shielded frame 2, clipboard 3, turntable 4, rotation hole 5, shaft 6, disk 7, screw rod 8, support rod 9, thread groove
10, screw rod 11, bolt hole 12 and shaft hole 13 match, since support rod 9 is set as cylindrical structure, and the bottom of support rod 9

Vertical state, opposite direction turn support rod 9, moves down support rod 9 in the outside of screw rod 8, and the bottom end of support rod 9 can be with
The top of turntable 4 is in contact, and multiple support rods 9 can be accommodated in the top of turntable 4, due to turntable 4 and U-shaped shielded frame 2
It is attached, U-shaped shielded frame 2 and turntable 4 can be disassembled from column 1 with column 1 by screw rod 11, realization pair
The fractured operation of whole device reduces the occupied space of whole device, and the utility model is designed reasonably, structure is simple, operation side
Just, the erection that clipboard 3 consolidates can be got up, and convenient for carrying out deconsolidation process to whole device, the occupancy for reducing device is empty
Between, consequently facilitating transported and stored, it is more practical.
Working principle: in use, since support rod 9 is set as cylindrical structure, and the bottom side of support rod 9 and turntable 4
Bottom is on same level axis, so the bottom side of multiple support rods 9 can be with ground when turntable 4 is placed on floor
Plate contact, and since support rod 9 is in contact with the outside of turntable 4 close to one end of column 1, turntable 4 can limit support rod 9
Position avoids support rod 9 from being folded upward at, at this time multiple support rods 9 can common column 1 be supported, so as to by book
Write that plate 3 is firm to be erected on floor, when need to split whole device transport when, turn support rod 9, so that support rod 9 exists
It is rotated on screw rod 8, due to being threadedly coupled between support rod 9 and screw rod 8, so that the one end and turntable of support rod 9 close to column 1
4 separation, push up support rod 9 at this time, and support rod 9 drives disk 7 to rotate in the outside of shaft 6, can will prop up by screw rod 8
Vertical state when strut 9 rotates, the support rod of opposite direction turn at this time 9, so that support rod 9 moves down in the outside of screw rod 8, this
When support rod 9 bottom end can be in contact with the top of turntable 4, multiple support rods 9 can be accommodated in the top of turntable 4, by
It is attached by screw rod 11 with column 1 in turntable 4 and U-shaped shielded frame 2, so can be by U-shaped shielded frame 2 and turntable
4 disassemble from column 1, realize to the fractured operation of whole device, reduce the occupied space of whole device, be convenient for transporting
It is defeated.
Although an embodiment of the present invention has been shown and described, it will be understood by those skilled in the art that: not
A variety of change, modification, replacement and modification can be carried out to these embodiments in the case where being detached from the principle of the present invention and objective, this
The range of invention is defined by the claims and their equivalents.
