The inner cavity of the carrying box 1 is convenient for the staff to place the recording paper, and it can also be adsorbed on the magnetic plate 6 by the magnetic block 61 as needed, which is convenient for the staff to view the data, etc. When the staff needs to wipe the recorded content, the servo motor 723 can be operated. When the servo motor 723 is running, it will drive the active bevel gear 722 to rotate. When the active bevel gear 722 rotates, it will pass through the driven bevel gear 7 21 drives the threaded rod 72 to rotate, and when the threaded rod 72 rotates, it drives the threaded sleeve B73 to move back and forth and left and right. When the threaded sleeve B73 moves left and right, it drives the wiping plate 75 to move back and forth and left and right on the recording plate 2 through the L-shaped connecting rod 74, so as to wipe the recorded inner cylinder, and when the threaded sleeve B73 moves, it drives the movable rack plate 82 to move, and when the movable rack plate 82 moves, it drives the movable gear 83 to rotate, and when the movable gear 83 rotates, it drives the rotating rod to rotate, and when the rotating rod rotates, it drives the movable bevel gear 832 to rotate through the rotating bevel gear 831, and when the movable bevel gear 832 rotates, it drives the reciprocating screw 84 to rotate through the rotating shaft, and when the reciprocating screw 84 rotates, it drives the screw nut 85 to move back and forth and left and right, and the screw nut 85 moves left and right When the piston 87 is moved to the left, the alcohol liquid in the alcohol tank 89 is sucked. When the piston 87 is moved to the right, the sucked alcohol liquid is transported to the spray pipe 10 and sprayed on the recording board 2 through the atomizing nozzle. It can cooperate with the wiping plate 75 to better wipe the content, and the operation is convenient. When the recording board 2 needs to be released from the clamping, the pressing plate 91 can be pressed forward, and the reset spring C912 will be squeezed at this time. At the same time, the sliding blocks 93 on both sides will be driven to move in the opposite direction through the hinged rod 92. When the sliding block 93 moves in the opposite direction, the movable plates 47 on both sides will be driven to move in the opposite direction through the adjacent fixed rod 94, which can drive the square rod 48 to move in the opposite direction, thereby staying away from the inner cavity of the adjacent square groove.The clamping and fixing of the recording board 2 can be released.
