The punching pressure knife 7 and the punching power mechanism are connected through a connection component. In the specific implementation process, the frame 1 is the support and installation main body of the binding machine. The punching power mechanism on the frame 1 is used as the power mechanism for binding. The punching power mechanism completes the actions of up and down telescoping and rotary punching. The operation platform 2 is used to place the printed paper for binding. The connection component is used to connect the punching pressure knife 7 and the punching power mechanism. The punching power mechanism pushes the punching pressure knife 7 to complete the operation of punching the paper.

[0022] According to the attached Figures 1-3 It can be known that the above connection component includes: a mounting block 3, a connecting drill bit 4, a threaded hole 5, an adjusting limit rod 6 and a limit hole. The connection relationship and positional relationship are as follows;

[0023] The end of the punching pressure knife 7 is provided with a mounting block 3 in a rectangular columnar structure. The bottom end of the punching power mechanism is a connecting drill bit 4. A jack matching the mounting block 3 is opened on the connecting drill bit 4. The mounting block 3 is inserted into the jack. A threaded hole 5 is opened on one side of the connecting drill bit 4. An adjusting limit rod 6 is threadedly connected in the threaded hole 5. The end of the adjusting limit rod 6 is inserted into the limit hole opened on the mounting block 3.

[0024] In the specific implementation process, the end of the punching pressure knife 7 is provided with a mounting block 3 which is a rectangular plate. The mounting block 3 at the end of the punching pressure knife 7 is inserted into the slot of the connecting drill bit 4. By rotating the adjusting limit rod 6 on the connecting drill bit 4 and moving linearly on the connecting drill bit 4, the adjusting limit rod 6 is inserted into the mounting block 3. Furthermore, the end of the adjusting limit rod 6 is inserted into the limit hole on the mounting block 3, thereby playing a limiting role on the mounting block 3 and preventing the mounting block 3 and the punching pressure knife 7 from detaching from the connecting drill bit 4. The punching pressure knife 7 can be effectively and quickly replaced through the adjusting limit rod 6.

[0025] As a preferred solution, furthermore, a magnetic attraction block 8 is installed inside the mounting block 3. A fixed magnetic block 9 is arranged at the inner end of the jack.

[0030] In the specific implementation process, the power motor 11 drives the telescopic push rod 12 to rotate, so that the telescopic push rod 12 drives the adjusting lead screw 13 to rotate, and then the adjusting lead screw 13 meshes with the adjusting nut 14, so that the linear rotational motion of the adjusting lead screw 13 drives the connecting drill bit 4 to press down and rotate, driving the punching cutter 7 to rotate and cut the printed paper.

[0031] As a preferred solution, further, a limiting and fixing strip 15 is arranged on the frame 1 on one side of the operation platform 2, which is used to display the highest paper stacking height.
