In addition to purlins, it can also be used as steel structure supports, beams, tension bars, etc. When the C-shaped steel is processed, in order to facilitate some processing of the C-shaped steel, a fixing device will be used to fix the C-shaped steel. The existing application number is: 202122825616.0. A C-shaped steel fixing device fixes the inner walls on both sides of the C-shaped steel through the cooperation between the telescopic rod and the fixed spring, reduces the hidden danger of deformation caused by the force brought by the clamping plate on both sides of the C-shaped steel, reduces its damage rate, and improves production efficiency. At the same time, through the sliding connection between the slide rail and the second slider, the connecting plate and the placement plate are moved, and C-shaped steels of different specifications can be clamped, which is more convenient and practical.

[0003] The above problem still exists. The C-shaped steel has a certain length. When it is placed and fixed, if the placement position of the C-shaped steel needs to be adjusted, installed or disassembled and moved, because the C-shaped steel is placed directly in contact with the placement plate, friction between the C-shaped steel and the placement plate may occur, increasing the difficulty of moving and making the operation relatively inconvenient.

Multiple groups of balls 18 are movably connected to the two groups of plate bodies 5. By utilizing the contact between the balls 18 and the wheel body 8 and the C-shaped steel, the C-shaped steel can be moved and guided, which can facilitate the disassembly and assembly of the C-shaped steel. At the same time, by adjusting the distance between the two groups of plate bodies 5, multiple groups of wheel bodies 8 can be brought into contact with C-shaped steels of different sizes, and when the plate body 5 further drives the first rubber pad 6 to fit tightly with the wheel body 8, the wheel body 8 can be pressed tightly against the C-shaped steel, so that the C-shaped steel can be fixedly placed.

[0024] In this embodiment, the frame body 1 is connected to two groups of support rods 10 by rotation through a connecting shaft. One group of support rods 10 is processed with multiple groups of holes 11. The inner wall gap of one group of holes 11 is matched with bolts 12.
