Description

An Improved Stapler

technical field

The utility model relates to a document binding device, in particular to an improved binder.

Background technique

In the daily file management process of enterprises and institutions, a large number of files need to be sorted, bound and archived for future reference. When the documents are bound, holes need to be punched at the edges of the documents, and then they can be bound and fixed with strings. When the existing binding equipment punches and binds a document with a large number of pages, it is prone to the problem that the file page cannot pass through smoothly due to the movement of the document page, and it is easy to tear the document page at the punching position when punching the hole , resulting in lower efficiency of document binding.

Utility model content

The technical problem to be solved by the utility model is to provide an improved binder, which can solve the deficiencies of the prior art and improve the efficiency of document binding.

In order to solve the problems of the technologies described above, the technical solutions adopted by the utility model are as follows.

An improved stapler, comprising a base, on which a bottom plate is fixed by first bolts, and a plurality of first through holes that communicate with each other are arranged on the bottom plate and the base. There is a pressure plate, and blind holes are arranged at both ends of the pressure plate, and an extension plate is movably inserted in the blind hole, and the top of the pressure plate is fixed by a second bolt to the extension plate, and the outer end surface of the extension plate is movably provided with a side plate perpendicular to the extension plate , the side plate is connected with the extension plate through a spring, the base is provided with a second through hole matched with the side plate, and the side plate is provided with a through groove in the same direction as the side plate, when the handle is pressed down and the side plate passes through Through the second through hole, the third bolt is inserted into the through groove and locked with a nut to realize the relative fixation of the side plate and the base. A perforator corresponding to the first through hole is provided in the middle of the pressure plate. The perforator includes A column, a cone is arranged on the top of the column, and arc-shaped blades parallel to the column are arranged on the side wall of the cone.

Preferably, a collecting tank is provided at the bottom of the base.

Preferably, several brackets are arranged on the base, the brackets are fixed to the base through fourth bolts, the top of the brackets is threaded with fifth bolts, and the bottom of the fifth bolts is connected with a pressure block through a universal joint.

The beneficial effect brought by the adoption of the above technical solution is that when punching holes, the relative stability of the document page can be kept through the limiting effect of the side plate. When the perforator presses down to punch holes, the third bolt is used to fix the side plate on the base, which can continue to keep the limit effect on the document page and avoid messing up the document page when the perforator is pulled up. When the file needs to be removed, the third bolt is loosened, and the side plate resets under the action of the spring. The extension board can be flexibly adjusted according to the size of the file. When punching, use the cone to puncture the paper, and then under the cutting action of the arc-shaped blade, the puncture part can be quickly cut into an approximately circular gap, thereby reducing the damage to the paper caused by direct puncture. The collection tank is used to collect the paper dust generated during punching. Using the pressing block to crimp and fix the document pages can further improve the relative stillness of the document pages during the binding process and avoid the problem of hole misalignment. By improving the accuracy of the binding process, the utility model reduces the time spent on unnecessary file arrangement and alignment, and improves the binding efficiency.
