DETAILED DESCRIPTION

[0026] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] Reference Figure 1-Figure 5 A crank-type press includes a base plate 1, with a first vertical plate 5 and a second vertical plate 14 symmetrically fixed to the top of the base plate 1. A double-headed screw 6 is rotatably installed between the upper parts of the first vertical plate 5 and the second vertical plate 14. A first nut seat 10 and a second nut seat 11 are installed on the double-headed screw 6 through thread transmission. A crank 13 is fixedly installed on one end of the double-headed screw 6; a first connecting rod 9 is hinged on the first nut seat 10, and a second connecting rod 15 is hinged on the second nut seat 11; the other end of the first connecting rod 9 is hingedly connected to the top of the pressing plate 2, and the other end of the second connecting rod 15 is hingedly connected to the top of the pressing plate 2, and the first connecting rod 9 and the second connecting rod 15 are symmetrically arranged. This press can be used to compress paper bills and documents, thereby ensuring reliable flattening and compression of the parts that need to be bound, facilitating subsequent binding operations and improving the efficiency of press binding. During specific use, the crank handle 13 is manually shaken, and the double-headed screw 6 is driven by the crank handle 13, and the first nut seat 10 and the second nut seat 11 are driven by the double-headed screw 6, and the pressure plate 2 is pressed down by the first nut seat 10 and the second nut seat 11, thereby achieving the compression of the bill.

[0028] Furthermore, both ends of the double-headed screw 6 are rotatably mounted between the first vertical plate 5 and the second vertical plate 14 through bearings 7. The bearings 7 ensure that the double-headed screw 6 can rotate smoothly, thereby improving its rotation efficiency.

[0029] Furthermore, the double-ended screw 6 is machined with a symmetrically arranged first thread segment 8 and a second thread segment 12. The first thread segment 8 and the second thread segment 12 are threaded in opposite directions. The first thread segment 8 forms a threaded transmission cooperation with the first nut seat 10, and the second thread segment 12 forms a threaded transmission cooperation with the second nut seat 11. The first thread segment 8 and the second thread segment 12 ensure that during the rotation of the double-ended screw 6, the corresponding first nut seat 10 and the second nut seat 11 can be synchronously driven to move in the same or opposite directions.

[0030] Furthermore, the top end of the first connecting rod 9 is hingedly connected to the first nut seat 10 via a first pin 16, and the other end of the first connecting rod 9 is hingedly connected to the first hinge seat 3 via a second pin 17. The first hinge seat 3 is fixed to the top end of the pressure plate 2. Through the above-mentioned hinge structure, the corresponding first connecting rod 9 is guaranteed to rotate smoothly.

[0031] Furthermore, the top end of the second connecting rod 15 is hingedly connected to the second nut seat 11 via a third pin 19, and the other end of the second connecting rod 15 is hingedly connected to the second hinge seat 4 via a fourth pin 18. The second hinge seat 4 is fixed to the top end of the pressure plate 2. The above-mentioned hinge structure ensures that the corresponding second connecting rod 15 can rotate smoothly.

[0032] Furthermore, the first connecting rod 9 and the second connecting rod 15 are both double connecting rods with symmetrical structures and are made of steel plates. The double connecting rod structure ensures structural stability and strength.

[0033] Working process and principle of this utility model:

[0034] By adopting the above-mentioned presser, during the specific use process, first place the paper to be pressed between the pressure plate 2 and the bottom plate 1, then manually turn the crank 13, and drive the double-headed screw 6 through the crank 13, and drive the first nut seat 10 and the second nut seat 11 through the double-headed screw 6, and drive the first connecting rod 9 through the first nut seat 10, and drive the second connecting rod 15 through the second nut seat 11, and then synchronously press down the pressure plate 2 through the first connecting rod 9 and the second connecting rod 15, and then press the bill through the pressure plate 2. After the bill is pressed, the part that needs to be bound is bound.
