[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0022] Reference Figure 1-3 , an accounting book punching machine includes a base plate 1, a gantry 2 is fixedly installed on the rear side of the top of the base plate 1, a cylinder 3 is fixedly installed on the top of the gantry 2, the output end of the cylinder 3 extends to the inner side of the gantry 2 and is fixedly installed with a movable plate 4, a pressing plate 5 is slidably installed between the left and right sides of the inside of the gantry 2, and the movable plate 4 is located directly above the pressing plate 5; the four ends of the top of the pressing plate 5 are fixedly installed with connecting components, the pressing plate 5 is connected to the movable plate 4 through four connecting components, the left and right sides of the bottom of the movable plate 4 are fixedly installed with slide rails 7, the movable plate 4 is installed with two punching components 8 through the two slide rails 7, and slide grooves 10 are opened on the left and right sides of the inside of the pressing plate 5, and the two punching components 8 correspond to the two slide grooves 10 respectively.

[0023] The cylinder 3 can drive the movable plate 4 to move up and down, and the movable plate 4 can move up and down through the connecting component and the pressure plate 5. When the user needs to punch holes in the account book, the punching part of the account book can be placed under the pressure plate 5, and then the cylinder 3 is started to drive the pressure plate 5 to move downward. After the pressure plate 5 contacts the account book, it will press the account book to prevent the account book from moving, and then the punching component 8 will drill holes in the account book.

[0024] The position of the punching assembly 8 and the punching spacing can be adjusted by the provided slide rail 7, and the user can flexibly adjust the punching position and the punching spacing according to needs.

[0025] A plurality of auxiliary lines 9 are provided on the upper surface of the bottom plate 1. The provision of the auxiliary lines 9 can facilitate the user to adjust the inclination of the account book and to straighten a crooked account book.

[0026] The connecting assembly includes a slide rod 6 and a spring 11. The top of the slide rod 6 passes through the movable plate 4 and extends to the top of the movable plate 4. The top of the slide rod 6 is fixedly installed with a limit block. The spring 11 is sleeved on the outer surface of the slide rod 6 and is located between the movable plate 4 and the pressure plate 5.

[0027] When the pressure plate 5 contacts the account book, the pressure plate 5 will be blocked by the account book and cannot move further. The movable plate 4 will compress the spring 11 and continue to move. The spring 11 will give downward pressure to the pressure plate 5, increasing the pressure of the pressure plate 5 on the account book, so that the account book will not move, avoiding the phenomenon of skewed punching.

[0028] The punching assembly 8 includes a punching rod 12, with an L-shaped mounting plate 13 fixedly mounted on the top of the punching rod 12. A locking bolt 14 is installed on the internal thread of one side of the mounting plate 13. Two locking bolts 14 are slidably mounted inside the two slide rails 7, and the mounting plate 13 is connected to the corresponding slide rail 7 via the locking bolts 14. The punching assembly 8 also includes an orientation sleeve 15, which is slidably mounted inside the two slide grooves 10, and the orientation sleeve 15 is sleeved on the outer surface of the punching rod 12.

[0029] The movable plate 4 can punch holes in the account book by pushing the punching rod 12, and the locking bolt 14 can slide inside the slide rail 7. By rotating the locking bolt 14, the mounting plate 13 can be fixed to the outer surface of the slide rail 7 to fix the punching rod 12. The setting of the directional sleeve 15 can prevent the punching rod 12 from deflecting and ensure that the punching rod 12 is always perpendicular to the base plate 1.
