When the elastic limiting portion 302 completely enters the limiting groove, due to the elastic properties of the elastic material, the elastic limiting portion 302 will return to its original shape and tightly fit into the limiting groove. At the same time, the arc-shaped fixing protrusion 303 on the elastic limiting portion 302 will also align with the fixed groove on the inner wall of the limiting groove and be clamped in, thereby further fixing the cloth drawing roller 4 to prevent it from slipping or shaking during rotation. Next, the driving device connected to the cloth drawing frame can be started to rotate the connecting piece 3 and the cloth drawing roller 4 together, thereby realizing the pulling of the cloth. When it is necessary to replace the cloth drawing roller 4, only the above steps are reversed to easily remove the cloth drawing roller 4 from the connecting piece 3 and replace it with a new one. When the cloth drawing roller 4 is installed on the connecting piece 3, it will naturally fall onto the arc-shaped support plate 9, which is supported by the roller 10. If the cloth drawing roller 4 sinks due to the weight of the cloth or other reasons, the elastic rod 8 will be compressed, and the spring will also be compressed, thereby providing an upward rebound force to ensure that the cloth drawing roller 4 always remains in the appropriate position. Through the design of the elastic rod 8 and the spring, the arc-shaped support plate 9 can provide a buffer layer for the cloth drawing roller 4 to prevent it from being damaged due to excessive force. This design is particularly suitable for handling heavy or thick cloth. The addition of the roller 10 significantly reduces the friction between the cloth and the support plate, which helps to prolong the service life of the cloth and reduce noise and energy consumption during production. Due to the elastic design of the elastic rod 8 and the spring, the arc-shaped support plate 9 can adapt to cloth drawing rollers 4 of different diameters and weights, improving the versatility and flexibility of the equipment. The combination of the arc-shaped support plate 9 and the roller 10 provides stable support for the cloth drawing roller 4, allowing it to run smoothly even at high speed or under heavy tension.
