The outer side of the movable column 11 is provided with multiple plug interfaces that are compatible with the action block 1204. The setting of multiple plug interfaces is conducive to controlling the height adjustment of the scaffolding, which is conducive to controlling the accuracy of the height adjustment of the scaffolding, and thereby helping to improve the use effect of the scaffolding. A movable through port is provided on the inner side of the fixed cylinder 10, and the movable column 11 is slidably connected to the fixed cylinder 10 through the movable through port. The outer sides of the four fixed cylinders 10 are fixed with adjustment components 12.

[0036] It should also be noted that the movable connection between the fixed tube 10 and the movable column 11 enables further adjustment of the scaffolding height. At the same time, the setting of the adjustment component 12 is conducive to the stability of the adjustment function and the flexibility and stability of the scaffolding.

[0037] It is not difficult to understand that a stabilizing component 13 is fixed between the left and right fixed cylinders 10, a protective platform 14 is fixed to the top of the movable column 11, and a locking component 15 is provided on the protective platform 14. The stabilizing component 13 includes a stabilizing plate and a stabilizing shaft.

The two upper hinged plates 7 are hinged to the fixed block 3 at the top, and the right side of the threaded rod 6 is fixed to the handwheel 8.

[0040] In this embodiment, the arrangement of the telescopic rod and the stabilizing component 13 is conducive to the stability of the entire scaffolding during use. The arrangement of the protective platform 14 is conducive to improving the safety of the scaffolding in use. The movable connection between the movable column 11 and the fixed tube 10 is conducive to the lifting and lowering of the scaffolding. At the same time, in conjunction with the arrangement of the lifting component, the height of the scaffolding is further adjusted, which is conducive to improving the flexibility of the entire scaffolding.

[0042] It can be found that the hinged setting is conducive to adjusting the folding block 1206, and then conducive to adjusting the action block 1204, thereby achieving a limiting effect on the movable column 11.

[0043] To put it simply, the left and right sides of the support spring 1203 are respectively fixed to the left side wall of the inner cavity of the positioning block 1201 and the left side of the action block 1204, the connecting column 1202 passes through the inner cavity of the positioning block 1201, the action block 1204 passes through the fixed cylinder 10 and the movable column 11 in turn, and the bottom of the inner cavity of the fixed cylinder 10 is fixed to the buffer block 1207.

[0044] In this embodiment, the action block 1204 is connected to the movable column 11 to achieve a limiting effect on the movable column 11. At the same time, the hinged setting of the folding block 1206 is conducive to improving the use effect of the entire component and improving the flexibility of the scaffolding.

[0045] See also Figure 3 In order to improve the safety of the scaffolding, the protective platform 14 in this embodiment includes a plate surface 1401, two connecting rods 1402, a connecting block 1403, a connecting plate 1404, an adjusting shaft 1405 and an adjusting plate 1406.

The setting of the return spring 1503 is conducive to the reset of the locking block 1504, which is conducive to the convenience of overall use. The top of the locking block 1504 is fixed to the return spring 1503. An opening for the displacement of the locking block 1504 is opened on the right side of the connecting block 1502. A locking hole is opened on the right side of the stabilizing block 1501, and the locking block 1504 is engaged with the locking hole.

[0048] As is well known, in this embodiment, the locking block 1504 is used to lock the locking hole, thereby limiting the connection plate 1404 and adjusting the protective platform 14, which is conducive to the convenience of overall use and the improvement of flexibility.

[0049] The working principle of the above embodiment is:

[0050] The scaffolding is moved to the required position by the casters 2. When the height of the scaffolding needs to be adjusted, the hand wheel 8 can be turned to drive the movable block 5 to move toward the middle under the action of the rotation. Under the hinged action of the lower hinged plate 4 and the upper hinged plate 7, the top plate 9 is pushed up, thereby promoting the overall height adjustment. If the height needs to be further adjusted, the plate surface 1401 can be pushed upward, and then the folding block 1206 is buckled downward to realize the engagement of the action block 1204 with the plug interface, thereby realizing the adjustment of the height of the plate surface 1401. At the same time, when the protective structure on the protective platform 14 needs to be raised, the connecting rod 1402 can be erected, and the locking block 1504 can be held and the bottom of the locking block 1504 is aligned with the locking hole. Then, the locking block 1504 is loosened and, under the action of the return spring 1503, the locking block 1504 is inserted into the locking hole to achieve overall fixation. The overall structure is conducive to achieving overall convenience by adjusting the height of the scaffolding. The overall structure is simple, the adjustable effect is good, and the flexibility is high.
