[0030] The specific usage and function of this embodiment are as follows:

[0031] In the utility model, Figure 1 As shown, the frame body 1 is in a pushable state, the outer circumferential surface of the movable roller 3 is in contact with the ground, the bottom end surface of the frame base 2 is not in contact with the ground, and the bottom end surface of the ground contacting circular plate 7 is off the ground, so that the frame base 2 can be pushed and adjusted by the movable roller 3; when Figure 1 When the frame body 1 shown in the figure is placed, the leveling screw barrel 5 is rotated by a tool to engage with the leveling screw 6, so that the leveling screw 6 descends through the thread engagement, and the leveling screw 6 drives the ground contacting circular plate 7 to descend synchronously, so that the bottom end surface of the ground contacting circular plate 7 touches the ground, and the outer circumferential surface of the movable roller 3 is separated from the ground. At the same time, the frame base 2 is leveled by adjusting the descending length of the leveling screw 6, thereby realizing the horizontal placement of the frame body 1.

[0032] Embodiment 2:

[0033] The difference from the first embodiment is that the regular hexagonal groove of the anti-rotation stud 4 can also be set as a regular heptagonal groove, so that the anti-rotation stud 4 can only be rotated by a special tool that cooperates with the regular heptagonal groove, preventing non-staff from rotating and disassembling the anti-rotation stud 4.

[0034] Embodiment three:

[0035] The difference from the first embodiment is that the bottom end surface of the ground contacting circular plate 7 can also be set as a frosted surface, thereby increasing the friction between the bottom end surface of the ground contacting circular plate 7 and the ground, preventing the ground contacting circular plate 7 from being displaced on the ground.
