[0027] How this utility works:

[0028] Refer to the instruction manual Figure 1-4 When in use, the staff first holds the handle 12, and then pushes the handle 12 upward, so that the handle 12 can drive the connecting plate 10 to move upward, and when the connecting plate 10 moves upward, it can drive the four push rods 9 to move upward, so that the four push rods 9 can drive the two pressing plates 7 to move upward and separate from the workbench 1. When the two pressing plates 7 are separated from the workbench 1, the staff puts an appropriate amount of printing paper on the top of the workbench 1, and then the staff stops pushing the handle 12. At this time, the four fixing springs 8 begin to extend outward after the external force disappears, so that the four fixing springs 8 can quickly drive the connecting plate 10 to move downward , so that the connecting plate 10 can quickly pull the two pressing plates 7 downward through the four push rods 9 to contact the printing paper, so as to quickly fix the printing paper on the workbench 1 for folding operation, so that the printing paper folding forming tooling, through the elastic action of the four fixing springs 8, the four fixing springs 8 can quickly drive the two pressing plates 7 to move downward through the connecting plate 10 to contact the printing paper, so that the two pressing plates 7 can limit and fix the position of the printing paper, thereby achieving the effect of quickly fixing the printing paper, so that the staff can quickly fold the printing paper, thereby improving the work efficiency;

[0029] Refer to the instruction manual Figure 1-4When the printing paper is fixed, the staff holds the hand plate 66 and moves the hand plate 66 downward, so that the hand plate 66 can drive the fan-shaped plate 62 on the right to rotate forward. When the fan-shaped plate 62 on the right rotates forward, it can drive the adjacent several tooth blocks 68 to rotate forward as well. When the several tooth blocks 68 on the right rotate forward, they mesh with the several tooth blocks 68 on the left, so that the several tooth blocks 68 on the left can quickly drive the adjacent fan-shaped plates 62 to rotate in the opposite direction, so that the fan-shaped plate 62 on the left can quickly drive the driving plate 64 to rotate downward. The downward movement of the driving plate 64 and the hand plate 66 can quickly drive the two movable plates 63 to start rotating toward the vertical state, so that the two movable plates 63 can quickly drive the indentation plate 4 to move downward through the I-shaped plate 611 to contact the paper to perform the folding operation, thereby making the printing paper folded. The hand plate 66 can be easily moved downward to make the hand plate 66 quickly drive the two movable plates 63 to rotate toward the vertical state, so that the two movable plates 63 can quickly drive the creasing plate 4 to move downward to crease the printing paper, so that the staff can complete the crease work on the printing paper effortlessly, reducing the labor intensity of the staff, thereby improving the practicality of the device to a certain extent. At the same time, after the crease operation is completed, the work only needs to release the hand plate 66. At this time, the reset spring 69 can quickly open the two movable plates 63 when the external force disappears, so as to quickly drive the creasing plate 4 to reset upward through the I-shaped plate 611 to prepare for the next crease operation, and then the staff repeats the above operation to crease more printing papers. The above is the entire working process of the utility model.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
