[0020] The adjustable drilling assembly 4 includes a frame 5, with its bottom ends fixedly mounted on the tops of two support frames 3. An adjustable motor 6 is fixedly mounted on the top of one side of the frame 5. A control switch 7 is fixedly mounted below the adjustable motor 6 and on the outside of the frame 5, and is energized to the adjustable motor 6. A bidirectional screw 8 is rotatably mounted inside the top of the frame 5, and the output shaft of the adjustable motor 6 passes through one side of the frame 5 and is fixedly connected to one end of the bidirectional screw 8. A threaded movable sleeve 9 is symmetrically threaded inside the frame 5 and on the outside of the bidirectional screw 8. A positioning slider 19 is fixedly mounted on the top of the threaded movable sleeve 9. A positioning groove 20 is symmetrically opened inside the top of the frame 5, and the positioning slider 19 is slidably mounted inside the positioning groove 20. A connecting shaft 10 is fixedly mounted at the bottom of the threaded movable sleeve 9, and a connecting strip 11 is rotatably mounted on the connecting shaft 10. A movable shaft 12 is rotatably installed at the end away from the connecting shaft 10. A movable strip 13 is provided at the bottom of the inner part of the frame 5, and two movable shafts 12 are fixedly installed at the top of both ends of the movable strip 13. Sliding connecting blocks 21 are fixedly installed at both ends of the movable strip 13. A sliding connecting groove 22 is symmetrically opened through the outer side of the frame 5, and the sliding connecting block 21 is slidably installed through the inside of the sliding connecting groove 22. A through hole 14 is evenly opened through the inside of the movable strip 13, and the through hole 14 is located directly above the bottom hole 2. A perforated tube 15 is fixedly installed at the bottom of the through hole 14, and a strip groove 16 is evenly opened on the outer side of the perforated tube 15. A positioning plate 17 is provided at the top of the movable strip 13, and both sides of the positioning plate 17 are fixedly connected to the inner wall of the frame 5. A stop rod 18 is evenly fixedly installed at the bottom of the positioning plate 17, and the bottom of the stop rod 18 movably passes through the through hole 14 and extends to the bottom of the inside of the perforated tube 15.

[0021] During use, the interaction of the supporting base plate 1, bottom hole 2, support frame 3, and adjusting punching assembly 4 enables the punching device for bookbinding to discharge paper scraps generated during punching, ensuring normal punching operation and thus achieving better practicality. Furthermore, the interaction of the positioning slider 19 and positioning groove 20 enables the threaded movable sleeve 9 to achieve better stability during movement, thereby ensuring that the adjusting punching assembly 4 can work stably.

[0022] Working Principle: During operation, the book to be punched is placed on top of the support base plate 1, ensuring the punching position is directly above the bottom hole 2. The book is positioned using an external clamping tool or manually by the operator. Then, the adjusting motor 6 is started, driving the bidirectional screw 8 to rotate. The bidirectional screw 8 moves the threaded movable sleeve 9, which in turn moves the positioning slider 19 within the positioning groove 20, ensuring better stability during movement. Simultaneously, the threaded movable sleeve 9 moves the connecting shaft 10, which in turn moves the connecting bar 11. The connecting bar 11 pushes the movable bar 13 downwards via the movable shaft 12, causing the movable bar 13 to move in the direction of the sliding connecting block 21. The sliding groove 22 allows for internal sliding, ensuring better stability of the movable bar 13 during movement. Simultaneously, the movable bar 13 drives the punching tube 15 downwards to punch holes in the books. After punching, the adjusting motor 6 rotates in the opposite direction, causing the punching tube 15 to move upwards and reset. Since the stop rod 18 remains stationary under the action of the positioning plate 17, the stop rod 18 pushes out any remaining paper scraps generated during punching downwards when the punching tube 15 moves upwards and resets, preventing paper scraps from remaining inside the punching tube 15 and ensuring normal subsequent punching operations. This allows the bookbinding punching device to discharge paper scraps generated during punching, ensuring normal punching operations and facilitating better practicality.
