The first movable plate 14 and the second movable plate 15 are convenient for improving the stability of the first limiting plate 2 and the second limiting plate 13 when moving.

[0024] As a further implementation scheme of the above technical scheme: the bottom ends of the two second limiting plates 13 are fixedly connected to the top of one of the first movable plates 14, the bottom ends of the other three second limiting plates 13 are fixedly connected to the top of another first movable plate 14, the bottom end of one of the first limiting plates 2 is fixedly connected to the top of one of the first movable plates 14, the bottom end of another second limiting plate 13 is fixedly connected to the top of the second movable plate 15, the first limiting plate 2 and the second limiting plate 13 are convenient for limiting the paper to avoid the paper being scattered.

[0025] As a further implementation scheme of the above technical scheme: a number of positioning grooves are provided inside the four positioning plates 6, and the side surfaces of the four positioning blocks 5 are respectively fitted with the insides of the corresponding four positioning grooves; two sliding grooves are provided inside the two limit frames 4, and the insides of the four sliding grooves are respectively fitted with the side surfaces of the four sliders 3, so that the positioning plates 6 facilitate limiting the positioning blocks 5.

[0027] In specific implementation: racks are fixed on one side of the two first movable plates 14, and gears are meshed between the racks. By moving one of the first limiting plates 2, the first movable plate 14 is driven to move, thereby driving the rack to move, thereby driving the gear to rotate, so that the two racks are moved closer to or away from each other, thereby driving the two first movable plates 14 to move closer to or away from each other, thereby driving one of the first limiting plates 2 and the five second limiting plates 13 to move closer to or away from each other, and by driving the other first limiting plate 2 to move left and right, the two first limiting plates 2 and the five second limiting plates 13 are moved closer to or away from each other. The spacing between the two ends of the first limit plate 2 is adjustable, so that the device can limit the paper of different sizes. When the first limit plate 2 needs to be moved, the handle 9 drives the rotating rod 8 to rotate, thereby driving the fixed plate 11 to rotate, so that the fixed plate 11 enters the first fixed groove, so that the rotating rod 8 loses the limit and can move up and down. The return spring 12 squeezes the pressure plate 7, thereby driving the pressure plate 7 to move up, thereby driving the limit frame 4 to move up, thereby driving the positioning block 5 to move up, so that the limit frame 4 and the positioning block 5 are automatically pulled up, so that the positioning block 5 is separated from the positioning plate 6, so that The first limit plate 2 loses its limit, and at this time, the first limit plate 2 can be moved without pressing the switch, which is convenient for applying force to the first limit plate 2, thereby improving the movement efficiency of the first limit plate 2. When the first limit plate 2 is moved, the pressure plate 7 is pressed to drive the limit frame 4 to move downward, thereby driving the positioning block 5 to move downward, so that the positioning block 5 enters the positioning plate 6, so that the limit frame 4 is limited. At this time, the rotating rod 8 is reversed by the handle 9, thereby driving the fixing plate 11 to reverse, so that the fixing plate 11 enters the second fixing groove and cannot move up and down, thereby limiting the rotating rod 8. The pressure plate 7 is limited, and the limit frame 4 is limited, and the positioning block 5 is limited and cannot move up and down, so that the first limit plate 2 is stably limited. The whole process only needs to drive the rotating rod 8 to rotate and press the pressure plate 7, which will not affect the limiting speed of the first limit plate 2 by the device. Therefore, the device can automatically lift the positioning block 5 through the reset spring 12 without affecting the limiting speed of the first limit plate 2, so that there is no need to press the switch when the first limit plate 2 moves, which is convenient for applying force to the first limit plate 2 and improves the movement efficiency of the first limit plate 2.

[0028] As a further implementation scheme of the above technical scheme: one side of the five second limiting plates 13 is provided with a mounting groove, and the inside of the five mounting grooves is fixed with a light belt 16, which is convenient for providing lighting.

[0029] As a further implementation scheme of the above technical scheme: a connection groove is opened on the side of the paper feed box body 1, and a conductive sheet 17 is fixed inside the connection groove. The conductive sheet 17 is easy to contact with the conductive block 19, so that the power supply is connected to the light strip 16.

[0030] As a further implementation scheme of the above technical scheme: a fixing seat 18 is provided inside the connecting groove, and a conductive block 19 is fixed inside the fixing seat 18 , so that the fixing seat 18 is convenient for limiting the conductive block 19 .

[0031] As a further implementation of the above technical solution: the conductive sheets 17 are electrically connected to the plurality of light strips 16 respectively, and the conductive blocks 19 are electrically connected to the power supply.

[0032] During specific implementation: the fixing seat 18 is fixed to the side of the printer. When printing is required at night, paper needs to be placed in the paper feed box body 1. When the light intensity at night is not enough, it is easy to affect the positioning efficiency of the paper. When the paper feed box body 1 is moved out of the printer, the conductive sheet 17 on the side of the paper feed box body 1 will move accordingly. When the conductive sheet 17 contacts the conductive block 19, a passage is formed between the power supply and the light strip 16, and the light strip 16 will light up to provide lighting for paper positioning. At this time, the paper can be placed between the first limiting plate 2 and the second limiting plate 13, and the paper is positioned by moving the first limiting plate 2 and the second limiting plate 13. After the positioning is completed, the paper feed box body 1 is put back into the printer, so that the conductive sheet 17 is separated from the conductive block 19, so that the light strip 16 is powered off, which is convenient for saving electricity. Therefore, the device can turn on the light strip 16 when positioning the paper, which is convenient for improving the positioning efficiency, and automatically turn off the light strip 16 after the paper positioning is completed, which is convenient for saving electricity.
