The resistive pen includes a pen body and a concave ring. The concave ring is located on the outer ring of the pen body. When the resistive pen is inserted into the support section, the support section is rotated to turn the resistive pen into the slot. At this time, the clamping part is aligned with the concave ring. The resistive pen is pressed into the clamping part, and the resistive pen enters the slot. The clamping part clamps the concave ring, fixing the resistive pen in the slot. The resistive pen is rotated outward, and the resistive pen pushes the clamping part and deforms it. The concave ring is dislodged from the clamping part, and the resistive pen is pulled out from the support section. Related operations are performed on the display section.

[0008] Furthermore, the printing unit includes a printer, a paper tray, a paper output port, and a plug.

The card plate is fixedly mounted behind the monitor.

[0010] Furthermore, the clamping part includes a connecting block, a retaining ring, a retaining end, and several teeth. One end of the connecting block is fixedly connected to the retaining plate, and the other end is fixedly connected to the retaining ring.

[0011] Furthermore, the front end of the retaining ring has a notch, through which the resistive pen enters and exits the clamping part. Both sides of the front end of the retaining ring are fixedly provided with clamping ends, and the teeth are fixedly provided on the inner surface of the retaining ring.

[0012] Furthermore, the resistive pen also includes several protrusions and a resistive pen tip. The protrusions are all fixedly disposed on the outer surface of the concave ring, and the resistive pen tip is fixedly disposed at the end of the resistive pen body for performing related operations on the display screen.

[0013] Furthermore, the support portion includes a support shell, a support cavity, and a ball bearing. The support cavity is located inside the support shell and communicates with the outside world, and is used to accommodate the resistive pen tip. A ball bearing is fixedly provided at the bottom of the support shell. The ball bearing is located on the upper surface of the printer and in front of the card slot. The ball bearing is rotatably connected to the printer.

[0014] Compared with the prior art, the present invention has the following beneficial effects: When the resistive pen is inserted into the support part, the support part is rotated to turn the resistive pen to the slot. At this time, the clamping part is aligned with the concave ring. The resistive pen is pressed into the clamping part, and the resistive pen enters the slot. The clamping part clamps the concave ring, fixing the resistive pen in the slot and preventing the resistive pen from being lost. The resistive pen is rotated outward, and the resistive pen pushes the clamping part and deforms it. The concave ring is dislodged from the clamping part, and the resistive pen is pulled out from the support part. The resistive pen is in an unrestrained state, which does not affect its flexibility and allows for accurate operation on the display part. Attached Figure Description

The resistive pen includes a resistive pen body 31 and a concave ring 32. The concave ring 32 is located on the outer ring of the resistive pen body 31. When the resistive pen is inserted into the support part, the support part is rotated to turn the resistive pen to the slot 24. At this time, the clamping part 25 is aligned with the concave ring 32. The resistive pen is pressed into the clamping part 25, and the resistive pen enters the slot 24. The clamping part 25 clamps the concave ring 32, fixing the resistive pen in the slot 24. The resistive pen is rotated outward, and the resistive pen pushes the clamping part 25 and deforms it. The concave ring 32 is dislodged from the clamping part 25, and the resistive pen is pulled out from the support part. Related operations are performed on the display part 2.

[0028] The printing unit 1 includes a printer 11, a paper tray 12, a paper output port 13, and a plug 14. The paper tray 12 is located on the upper rear side of the printer 11 and is used to hold printing paper. The paper output port 13 is located in the middle of the front of the printer 11. The printed hazardous chemical labels are taken out from the paper output port 13. The plug 14 is fixedly located on the side of the printer 11 and is used to connect to an external power source. When the plug 14 is connected to an external power source, the printing terminal can be used normally.

[0029] The display unit 2 also includes a display 21 and a display screen 22. The display 21 is fixedly mounted above the printer 11, and the display screen 22 is fixedly mounted on the front of the display 21 for displaying information of hazardous chemical labels.

[0030] The clamping part 25 includes a connecting block 251, a retaining ring 252, a retaining end 253 and a plurality of teeth 254. One end of the connecting block 251 is fixedly connected to the retaining plate 23, and the other end is fixedly connected to the retaining ring 252.

[0031] The retaining ring 252 has a notch at the front end, through which the resistor pen enters and exits the clamping part 25. Both sides of the front end of the retaining ring 252 are fixedly provided with a retaining end 253. The retaining end 253 is arc-shaped and bent outward to facilitate the entry and exit of the resistor pen from the retaining ring 252. The teeth 254 are fixedly provided on the inner surface of the retaining ring 252 to increase the friction of the retaining ring 252, which is beneficial for the retaining ring 252 to hold the resistor pen.

[0032] The resistor pen also includes several protrusions 33 and a resistor pen tip 34. The protrusions 33 are all fixed on the outer surface of the concave ring 32 to increase the friction of the concave ring 32. The protrusions 33 and the teeth 254 cooperate with each other to make the retaining ring 252 hold the resistor pen more firmly. The resistor pen tip 34 is fixed on the end of the resistor pen body 31 and is used to perform related operations on the display screen 22.

[0033] The support includes a support housing 35, a support cavity 36, and a ball bearing 37. The support cavity 36 is located inside the support housing 35 and communicates with the outside.

[0034] Plug 14 into the socket to connect printer 11 to an external power source, allowing printer 11 to print. Press and hold the resistive pen body 31 and pull it outwards from the slot 24. The resistive pen body 31 pushes the retaining ring 252 to both sides, causing the retaining ring 252 to deform and the concave ring 32 to disengage from the retaining ring 252. Pull the resistive pen body 31 upwards to allow the resistive pen tip 34 to leave the support cavity 36. The resistive pen part 3 is now unrestrained and its flexibility is not affected. Use the resistive pen part 3 to perform relevant operations on the display screen 22 to initiate the printing of hazardous chemical labels and output paper. Take out the printed hazardous chemical label from port 13, hold the resistor pen body 31 and insert the resistor pen tip 34 into the support cavity 36 to fix the resistor pen in the support. Push the resistor pen body 3, and the ball bearing 37 rotates on the printer 11. Rotate the resistor pen body 3 to the slot 24. At this time, the clamping part 25 is aligned with the concave ring 32. Press the resistor pen into the clamping part 25. The resistor pen pushes the retaining ring 252 to both sides, causing the retaining ring 252 to deform. The concave ring 32 slides into the retaining ring 252, and the retaining ring 252 locks the concave ring 32, fixing the resistor pen in the slot 24 to prevent the resistor pen from being lost.
