[0023] It should be noted that through the cooperative setting of structures such as the quantitative cavity 1, the visual measuring plate 4, the sealing cover plate 8, the fixing frame 13, the pushing plate 19 and the quantitative adjustment component, the amount of discharged material can be conveniently adjusted, so that the amount of discharged material can be controlled according to the size of different storage containers, the accuracy of discharging can be improved, and the situation of excessive discharged material and waste can be effectively reduced.

[0025] Furthermore, the pushing plate 19 is a partition for quantitatively regulating the coating inside the quantitative cavity 1 and plays a role in pushing and discharging the material. The connecting plate 15 is a structure for sealing with the pushing plate 19 to ensure that there is no coating backflow during the discharging process. The anti - detachment plate 17 plays a role in limiting the position of the connecting plate 15 to prevent the connecting plate 15 from falling off. The connecting guide rod 16 is a structure connecting the connecting plate 15 and the anti - detachment plate 17. The assembly cavity 22 plays a role in limiting the anti - detachment plate 17 to ensure the structural stability and provides a certain protection for the compression spring 18.
