When the leather is laid, the staff will place the pressing strip between the two limit columns. Since the spring is in a pulled state, the spring will exert a downward force on the pressing strip, so that the leather can be pressed and smoothed. The leather can be pressed and smoothed without adjustment, which increases the processing efficiency of the leather seat cover.

[0014] 2. When the leather processing and stitching are completed, the staff will push the leather down from the top of the work plate, and the pushed leather will fall into the storage box. When the storage box is full of leather, the staff will pull the storage box out from between the two fixed plates and replace it with an empty storage box, which is convenient for storing and transporting the processed and stitched leather, increasing the convenience of leather processing;

[0015] 3. When the staff lifts up the pressing strip to provide space for laying the leather, the staff will store the pressing strip inside the storage bracket, freeing the staff's hands. When sewing the leather, if the brightness of the surrounding environment is dim, the staff will turn on the light tube and turn the metal bellows to adjust the position of the light tube to increase the brightness and protect the staff's eyesight. When the pressing strip is pressed on the surface of the leather, the roller will contact the leather, reducing the friction between the pressing strip and the leather, making it easier for the staff to pull the leather and move it for sewing.
