[0023] In a preferred embodiment, the fixing structure 1 includes a handle 101, a movable groove 102, a connecting rod 103, a gravity block 104, a limiting groove 105, and a positioning plate 106. The positioning plate 106 has a limiting groove 105 on its front surface and is fixedly installed inside the printing press. The upper surface of the positioning plate 106 has a movable groove 102, and the connecting rod 103 is embedded in the movable groove 102. The handle 101 is fixedly installed on the upper surface of the connecting rod 103, and the gravity block 104 is fixedly installed on the lower surface of the connecting rod 103. The gravity block 104 has a large mass, so when there is no external force, the gravity block 104 always stays in front of the positioning shaft 302. Even if the printing press shakes slightly during operation, it will not affect the stability of the gravity block 104.
[0024] In a preferred embodiment, the printing roller body 3 includes a roller body 301, a positioning shaft 302, an embedding groove 303, and a second screw hole 304. The positioning shaft 302 is fixedly installed on both sides of the roller body 301. There are two sets of positioning shafts 302. In use, the positioning shafts 302 are connected to the drive structure inside the printing press. The drive structure drives the positioning shafts 302 to rotate, thereby driving the printing plate body 201 to rotate and perform printing operations.

[0026] The gravity block 104 is lifted upward by the handle 101, and the positioning shaft 302 is embedded into the limiting groove 105. The positioning shaft 302 is connected to the drive structure. After releasing the handle, the gravity block 104 moves downward under its own gravity and limits the positioning shaft 302, so that the positioning shaft 302 always stays in the center position of the limiting groove 105.
[0027] In a preferred embodiment, the printing plate body 2 includes a plate body 201, a first connecting plate 202, an embedding rod 203, a second connecting plate 204, a bolt 205, and a first screw hole 206.

The embedding rod 203 is fixedly installed on one side surface of each of the first connecting plates 202. The second connecting plate 204 is movably connected to the other side surface of the plate body 201. There are two sets of the second connecting plates 204. The first screw hole 206 is opened on one side surface of each of the second connecting plates 204.
[0028] In a preferred embodiment, the main body 201 of the printing plate is fitted onto the surface of the roller 301, which serves as a positioning element. The main body 201 of the printing plate is always fitted onto the surface of the roller 301. The embedded rods 203 are respectively embedded into the interior of the embedded grooves 303. The bolts 205 are embedded into the interior of the first screw hole 206 and the second screw hole 304. There are two sets of bolts 205.
[0029] When the printing plate body 201 needs to be replaced, the roller body 301 is disassembled, the bolts 205 are loosened and the second connecting plate 204 is flipped over, and the printing plate body 201 is pushed to one side so that the embedding rod 203 is away from the embedding groove 303. The printing plate body 201 can then be removed. The new printing plate body 201 is placed on the surface of the roller body 301 so that the embedding rod 203 is embedded in the interior of the embedding groove 303. The second connecting plate 204 is flipped over so that the second connecting plate 204 contacts the roller body 301. The bolts 205 are embedded in the interior of the first screw hole 206 and the second screw hole 304 for fixation, and the printing roller body 3 is fixed inside the fixing structure 1.
[0030] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
