The inner walls of the two concave plates 11 are sleeved and connected with moving rods 12. The opposite ends of the two moving rods 12 are slidably connected to the inner walls of the two fixed plates 10. Among them, referring to Figure 5 , air flow fans 13 are fixedly connected to the four corners of the inner wall of the top end of the rectangular outer shell 1 for sucking up the thread ends. Among them, referring to Figure 2 , protection plates 3 are fixedly connected to the front and rear sides of the bottom end of the rectangular outer shell 1. A handle 2 is fixedly connected to the front end of the rectangular outer shell 1.

[0031] Specifically, the air flow fan 13 is started by the controller, and the protection plate 3 at the bottom of the rectangular housing 1 is aligned with the thread end after the sewing of the soft-pack bed leather material. The thread end is adsorbed to the bottom of the rectangular housing 1 under the action of wind. The motor 5 is started to rotate the first straight gear 6, thereby driving the second straight gear 24 to rotate. The first straight gear 6 and the second straight gear 24 drive the rotating rod 25 to rotate. The rotating rod 25 drives the eccentric wheel 7 to rotate. The eccentric wheel 7 drives the L-shaped plate 8 and the cutting knife 9 to perform reciprocating arc-shaped motions to cut the thread end. The concave plate 11 moves due to the eccentric wheel 7, driving the moving rod 12 to slide on the fixed plate 10.

Through the upgrade and transformation of the thread end removing device, there is no need to manually hold scissors to remove the sewing thread ends of the soft-pack bed leather, saving operation time and improving production efficiency. While removing the thread ends, the static electricity adhesive plate 15 is turned on through the controller to adsorb the cut thread ends. When cleaning the static electricity adhesive plate 15, the round rod 16 is toggled to drive the slide rod 17 to move. The slide rod 17 drives the limit rod 18 to move and resets the spring 20, so that the ring 19 disengages from the slot 23. Then, the static electricity adhesive plate 15 is taken out of the rectangular housing 1 for cleaning, which can efficiently clean the ground wire ends on the static electricity adhesive plate 15, facilitate the operation of the staff, and improve the practicability of the device.
