[0027] Cloth needs to be placed on the workbench when sewing, but due to the flexible structure of the cloth, it may cause wrinkles or folding under the influence of force. The structure drives the output end of the first deviation correcting motor 5 to generate driving force through the connection of the power supply, thereby driving the horizontal transmission belt 9 and the transmission wheel 8 to make angle adjustment. When the transmission wheel 8 rotates, it drives the adjusting frame 7 to move together, thereby completing the adjustment of the vertical movement of the adjusting frame 7.

[0033] The inside of the adjusting frame 7 is provided with a buffer spring 17 for buffering the force; the buffer spring 17 can effectively absorb and relieve the vibration and impact generated during the operation of the equipment, reduces the damage of components or structures caused by the vibration force, prolongs the service life of the equipment, reduces the vibration through the buffer spring 17, helps to improve the stability of the equipment during the operation, and improves the precision and consistency of the cloth processing.
