Description

Technical Field

[0001] The invention relates to the technical field of fixing and compressing tissue paper packages in ordinary life, and in particular to a parallel compression tissue paper clip. Background Art

[0002] In people's daily life, paper bags are very common items, and their convenience and beautiful appearance make them popular. However, in order to reduce costs and prices, manufacturers usually design the outer packaging of paper bags into a very simple rectangular outer packaging, so they do not have the ability to be fixed on other objects, such as walls, in terms of function. In addition, the simple outer packaging will also gradually reduce the height of the paper in the package when it is gradually reduced during use. When the paper is used to a certain extent, it will not be taken out of the package and the phenomenon of breaking will occur. After the paper is broken, it is difficult to take it out of the package again, which makes people very distressed. However, the common paper box does not have the function of compressing the height of the paper bag. Even if some styles can achieve the compression of the height of the paper bag, its outer dimensions are relatively large, so it is difficult to use it when carrying it out or in a place with a relatively small space. Therefore, it has become a trend in this industry for technicians in this field to develop a parallel compression paper clip that can be easily fixed on the wall, is compact in size, and can compress the height of the paper bag. Summary of the invention

[0003] The present technical scheme provides a parallel compression paper clip which is compact in size and can compress the height of a paper bag. A pressure plate and a seat plate are respectively arranged at the upper and lower ends of the paper bag, and a parallel contraction device is arranged between the pressure plate and the seat plate so that the pressure plate and the seat plate can approach each other to clamp and compress the paper bag.
