Description

Unlimited width stapler

Technical Field

The invention relates to a stapler, in particular to an infinite width stapler.

Background

The existing stapler has a defect which can not be overcome: because the body of the stapler is hinged with the connecting frame at the rear end part through the hinge shaft, when the breadth of the paper stack to be bound is large, the hinged part can block the feeding of the paper stack, so that the staple outlet at the front end can not extend to the binding part of the paper stack, and the binding range of the stapler is limited.

In order to solve the above problems, utility model patent ZL201120391114.5 discloses an improved extendable stapler, which is characterized in that when the width of the paper stack to be bound is large, the upper and lower fence extension devices can be extended to a required length and fixed by an upper extension fixing piece 6, a lower extension fixing piece 7 and an adjusting bolt 8, so as to form the extendable stapler. This structure still has major drawbacks: firstly, the length increased by the upper and lower fence expansion devices is limited, and the upper and lower fence expansion devices cannot be used for binding paper with larger breadth; secondly, the length adjustment is needed in each use, which is complicated and the upper part and the lower part are not easy to align.

Utility model patent ZL200720122161.3 discloses a "stapler", when the paper that waits to bind is folded the breadth and is great, the paper is folded and is sent into the in-process, touches fuselage 20 and frame 10 articulated department and can roll over in the department of the letter U that falls of fuselage 20. This configuration still has the drawback of limited binding range because the inverted U-shaped size of the body 20 is limited and the stack of sheets to be inserted is necessarily limited.
