[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The device is provided with a smoothing device. When in use, the cylinder in the smoothing device controls the moving wheel to slide inside the slide groove, driving the movable block at the bottom to move synchronously, thereby bending the second connecting rod, driving the driven plate to move downward and push out to both ends, driving the smoothing plate at the bottom to smooth the cloth on the operating table, so that the device can smooth the cloth through the smoothing device when in use, reducing the negative impact caused by cloth wrinkles during sewing;

[0014] 2. The device is provided with a connecting plate and a second movable shaft. When the driven plate is pushed out and moved toward both ends by force, the second movable shaft installed on the driven plate drives the first connecting rod to rotate inside the connecting plate, so that the two ends of the driven plate in the device are always at the same height when the driven plate moves. Therefore, the device can ensure that the smoothing plates are at the same height when the cloth is smoothed during use, thereby preventing the occurrence of poor smoothing effect due to uneven smoothing angles.
