Its technical solution includes a limit frame, a support plate, and a connecting plate. Fixed blocks are fixed to the lower ends of both sides of the limit frame, each with a limit hole in the middle. The limit plates are fixed to both sides of the limit frame by springs. Support plates are fixed to the four corners of the upper end surface of the limit frame, with limit slots equidistantly defined on the outer sides of the support plates. A rotating shaft is fixed to the middle of the upper end surface of the connecting plate, with a limit clamp movably mounted on the shaft. The ends of the connecting plate are mounted within the limit slots. Four fixed blocks are provided, one at each end of the limit frame. The rotating shaft and the limit clamp are of equal length, and the limit clamp is arc-shaped. This utility model facilitates support and fixing of paper and other printed products.

[0003] The supporting and fixing device for printing printed materials in the above-mentioned patent has the following shortcomings: when the device is in use, it is necessary to adjust the connecting plate to the appropriate limit groove in real time according to the height of the printed product so that the limit clamp can play a role in limiting and fixing the top of the paper or printed material. Frequent adjustments make it more troublesome to use. For this reason, a supporting and fixing device for printing printed materials is designed. Utility Model Content

During the backward movement of sliding rod 20, it slides inside L-shaped rod 25, so that rotating rod 15 and pressing plate 16 are lifted, and the other ends of two sliding rods 19 are fixedly connected to the same cross bar 18, and the middle part of the other end of cross bar 18 is rotatably connected to push rod 22, and the other end of push rod 22 is fixedly connected to push handle 23, and the end of push rod 22 close to cross bar 18 is fixedly connected to block 24.

[0023] In this embodiment, a U-shaped rod 21 is fixedly connected to one end of the top of the mounting plate 14 near the cross bar 18, and the U-shaped rod 21 is adapted to the block 24. The same protective cover 17 is fixedly connected to both sides of the mounting plate 14, and a circular hole adapted to the push rod 22 is opened at one end of the protective cover 17 near the push rod 22.

[0024] In this embodiment, the same bidirectional screw rod 6 is rotatably connected between the two ends of the inner side of the bar frame 5, and screw blocks 7 are threaded through both ends of the bidirectional screw rod 6. Screw nuts that are compatible with the bidirectional screw rod 6 are fixedly sleeved on the two screw blocks 7. The two screw blocks 7 are fixedly connected to a limiting plate 8 on one side near the middle of the L-shaped top plate 4.

[0025] In this embodiment, one end of the bidirectional screw rod 6 passes through the bar frame 5 and is fixedly connected to the first pulley 9 . A round hole adapted for the bidirectional screw rod 6 is opened at one end of the bar frame 5 .

[0026] In this embodiment, the L-shaped top plate 4 is rotatably connected to the second pulley 11 at one end on the same side as the first pulley 9, and the same belt 10 is sleeved between the second pulley 11 and the first pulley 9. The second pulley 11 is rotatably connected to the circumferential edge of the side away from the L-shaped top plate 4 with a crank 12. By rotating the crank 12, the two limit plates 8 can approach and move away from each other, thereby realizing the limitation of both sides of the printed matter.

[0028] Working principle: When in use, push the push handle 23 to move the block 24 to the rear side of the U-shaped rod 21 and rotate the push handle 23 so that the block 24 is stuck on the U-shaped rod 21. At this time, the sliding rod 20 slides into the strip gap between the L-shaped rod 25 and the rotating rod 15, so that the rotating rod 15 lifts one end of the pressure plate 16. At this time, place the printed matter in the middle of the L-shaped top plate 4, and rotate the crank 12 so that the second pulley 11 rotates with the first pulley 9 and the bidirectional screw rod 6 through the belt 10, so that the two limit The plates 8 are close to each other, so that the two limit plates 8 limit the printed matter so that the printed matter will not be disordered. Then the push handle 23 is rotated to separate the block 24 from the U-shaped rod 21. Under the action of gravity, the pressure plate 16 brings the rotating rod 15 down, so that the pressure plate 16 tightly presses the top of the printed matter, thereby limiting and fixing the top of the printed matter without affecting the taking of the printed matter. Each time the printed matter is taken, the pressure plate 16 presses the top of the printed matter under the action of gravity, without the need for frequent manual adjustment, and is easy to use.
