Paper stopper positioning mechanism of stapler

The present invention relates to a stapler transaction apparatus for document paper binding, in particular, a paper stopper positioning mechanism capable of maintaining the position of binding for binding stapled paper, and avoiding misalignment of paper.

According to the conventional stapler, a stapler for binding a layer of paper or the like, the stapler has a paper stopper positioning mechanism for binding the document paper, so that the stapled paper is stopped at the paper stopper positioning mechanism. Next, it is ensured that the document paper to be bound does not cause the position binding phenomenon. As shown in the eighth figure, the conventional paper stopper positioning mechanism is provided with a paper block (62) and a bolt on the base (61) of the stapler. a rod (63), an elastic ring (64) and a fastening piece (65), the bolt (63) extends through the paper block (62) and the base (61), and cooperates with the elastic ring (64) And the fastening piece (65) is pivoted from the lower end of the base (61) corresponding to the bolt (63), so that the paper block (62) can be slidably disposed on the base (61), so that the document paper to be bound can be Binding is performed according to the edge of the paper block (62), and it is ensured that the distance between the document binding and the edge of the binding is equidistant width, so as to complete the positioning function of the document paper binding.

However, the paper block (62) is only horizontally elastically fixed to the base (61) by the elastic ring (64), and the elastic bonding force is easily affected by the impact force of a large number of documents to be bound. The elasticity of the elastic ring (64) is not able to stop the impact force, so that the paper block (62) is pushed and pushed to generate a sliding displacement, thereby affecting the function of the paper stop positioning, and there is a doubt that the binding quality is lacking.

Based on the above assembly methods, it is necessary to take into account the condition of the spring restoring force. The loading or the elastic force is not enough to stop the inconvenience, so the industry has developed a conventional paper retaining mechanism as shown in FIG. 9 , which has a stud (72) extending from the bottom end of the block (71). The end of the stud (72) is outwardly formed with an arcuate elastic card (73) toward the two sides, so that the block (71) itself can form an arcuate arc bump by the end of the arcuate card (73). (74) elastically clamped to the base (80); the conventional paper block (71) does not need to be provided with any elastic member, but the arc bump (74) and the block (71) are clamped against the base ( 80) The elastic force, in the case of encountering a large amount of paper to be bound to the impact of the paper block (71), without any jamming function, it still can not resist the sliding displacement of the paper block (71) As can be seen from the above, although the paper-stopping mechanism of the stapler has many styles, the structure design is not perfect, so the function of the paper-blocking position is easily hindered, resulting in the paper-bound binding of the document.
