The bracket includes supporting legs on both sides and two connecting rods on the supporting legs, and the two connecting rods are connected by a pair of parallel guide rails.

The workbench includes a worktable and a pressure rod on it. The upper part of the pressure rod is provided with a thread, and a wing nut is screwed on the thread. The lower part of the wing nut is provided with a pressure plate set on the threaded part of the pressure rod. The worktable is sleeved on the guide rail through the linear bearing fixed at the bottom.

The crank-slider grooving mechanism consists of two supports fixed on the ends of the two brackets respectively. There is a slot in the middle of the support, and a narrow slit at the same height as the slot is opened on the side of the slot. Slider, a saw blade is fixed on the side of the slider, and the saw blade protrudes out of the support through a narrow slit; one end of the slider and the rocker is hinged by a screw, the other end of the rocker is hinged on the crank through the first bolt and the first nut, and one end of the crank is passed The second bolt and the second nut are hinged on the support, and the other end is connected with a driving handle.

For thick book binding, the steps are as follows:

1) Put the sorted thick bound book on the workbench, with 2~3 cm exposed from the side to be bound, and then press it tightly with a wing nut;

2) Move the workbench to the crank slider sawing mechanism on one side, turn the drive handle, the crank drives the rocker to drive the slider with the saw blade fixed up and down, and at the same time slide the workbench slowly to realize the feed and realize sawing to be bound side slots until the saw blade is fully submerged to complete the feed;

3) Stop turning the driving handle, move the worktable in reverse to the crank slider sawing mechanism on the other side, turn the driving handle so that the crank drives the rocker to drive the slider fixed with the saw blade to move up and down, and saw the groove on the other side , until the saw blade is completely submerged, and the feeding is completed;

4) After the saw groove is completed, move the workbench to the middle position, and insert the raised parts of the two ends of the U-shaped tubular bottom binding needle into the saw grooves at both ends of the side to be bound;

5) Insert the protruding parts of the two ends of the U-shaped upper binding pin into the U-shaped tubular lower binding pin, and use a small hammer to tap until the paper is pressed tightly, and the U-shaped tubular lower binding pin and the U-shaped upper binding pin have an interference fit;

6) Loosen the wing nut to take off the thick bound book, and the binding is complete.

The utility model uses U-shaped needles (composed of two parts, the upper binding needle and the lower binding tubular needle) for binding; the binding cut is obtained by sawing grooves at the upper and lower sides. The workbench can slide left and right to complete the saw grooves at both ends of the thick book to be bound.

The beneficial effect of the utility model is that the utility model realizes the binding by the interference fit method of the upper and lower U-shaped needles after the saw blade is slotted, has a simple structure, is convenient to use, low in cost, and has a good binding effect. The utility model can be widely used in the binding work of test papers, newspapers, magazines, files and files of schools, financial institutions, state agencies and other departments.
