Description

Technical Field

[0001] The utility model relates to the field of binding machines, in particular to a resetting mechanism of a binding machine. Background Art

[0002] A binding machine, also called a stapler, is a tool that can bind multiple pages of paper together for preservation. There is at least one stapler in every office. In fact, the earliest stapler was not an office supply at all. It was developed for the printing industry.

[0003] The existing binding machine needs to be manually stapled. When loading staples, the top cover of the binding machine must be opened and the reset mechanism must be pushed backward. When the reset mechanism is reset, the staples are often knocked out of the staple groove or the staple row is disconnected due to excessive elasticity. The stapling operation is more troublesome and brings inconvenience to the user. Therefore, a reset mechanism for a binding machine is proposed to address the above problems. Utility Model Content

[0006] The reset mechanism comprises a push block, which is slidably mounted inside the placement bin. A spring is mounted inside the placement bin to reset the placement bin, and a baffle is movably mounted on the top of the push block.

[0007] Preferably, a slide groove is provided on the lower end surface of the baffle, a protrusion is fixedly connected to the top of the push block, the protrusion is adapted to the slide groove, and the protrusion is slidably set in the slide groove, a spring 2 is rotatably installed on the top of the baffle, and the end of the spring 2 away from the baffle is rotatably installed on the inner wall of the top cover.

[0008] Preferably, the two sides of the push block are symmetrically fixedly connected to a limiting block one, a limiting guide rail one is provided on the side wall of the placement bin, and the limiting block one is slidably installed in the limiting guide rail one.

[0014] 1. The utility model is convenient for pushing the stapler to continuously move toward the exit position by setting a reset mechanism. When in use, the push block is pushed to move by a spring, thereby squeezing the stapler to the staple exit position. In addition, a baffle is set on the top of the push block so that the top of the stapler in front of the push block can be limited by the baffle to avoid the middle of the stapler from bulging upward due to being squeezed by the push block, causing the staple row to be disconnected, thereby ensuring that the stapler can be stably and sequentially moved to the exit position in the installation order.

[0015] 2. The utility model installs a magnetic block at the bottom of the push block, and the magnetic block and the placement bin are attracted to each other, which can offset part of the thrust provided by the spring, so that the push block slowly approaches the staple, thereby preventing the push block from quickly colliding with the staple, so as to include the integrity of the staple, and effectively prevent the staple from being squeezed and bulged from the middle and then broken, affecting the use; in addition, by setting the magnetic block, the push block and the baffle can achieve differential movement, so that the baffle quickly covers the top of the staple to protect the staple.
