Abstract
The utility model relates to office supplies, in particular to a document stapling tool, and provides a punching mechanism of a stapler. The punching mechanism of a stapler comprises a slide block, a connection rod, a hinge shaft, a support, a handle, a drilling tool, a pressing plate and a mandril, wherein the support is fixedly connected on a base seat, the slide block can be connected on the support in a vertically sliding mode, the hinge shaft is connected on the support, the upper portion of the connection rod is hinged with the handle, and the lower portion of the connection rod is connected with the hinge shaft. The mandril is arranged on the handle in a hinged mode, the other end of the mandril is hinged with the slide block, the lower portion of the slide block is connected with the pressing plate, and a pressure spring is further arranged between the slide block and the pressing plate. The punching mechanism is achieved through a planar linkage mechanism which is formed by a plurality of components connected through revolute pairs, and the planar linkage mechanism is also known as a planar lower pair mechanism. The revolute pairs are in contact with cylindrical surfaces, and are high in carrying capacity, wearproof, and simple and convenient to manufacture, and high manufacturing precision is easy to obtain.
Description
Technical field
The utility model relates to a kind of office appliance, particularly a kind of document binder.
Background technology
Many occasions such as finance and file administration need to be bound file.The major function of stapler is punching, and the primary structure of present perforating mechanism is rack-and-pinion, and complicated in mechanical structure, cost is high and easy break-down.The utility model has been developed linkage and has been used for realizing punching functions.
The utility model content
The utility model provides a kind of perforating mechanism of stapler, and the handle that is used for the realization stapler drives the brill cutter in the process that presses down and penetrates paper.
A kind of perforating mechanism of stapler, comprise slide block, connecting rod, hinge axis, support, handle, brill cutter, pressing plate, mandrel, described support is fixed on the base, described slide block can vertically be slidably connected on the described support, described hinge axis is connected on the described support, the top of described connecting rod is hinged with handle, the bottom of described connecting rod is connected with hinge axis, is hinged with mandrel on the described handle, and the other end of described mandrel and described slide block are hinged; The bottom of described slide block is connected with described pressing plate, also is provided with holddown spring between described slide block and the described pressing plate.
Compare with conventional art, the beneficial effects of the utility model are:
Simple in structure, compact, long service life of the present utility model.
Perforating mechanism adopts planar linkage mechanism to realize, it is the plane mechanism that is connected to form with revolute pair by some members, claims again planar lower pair mechanism.Revolute pair contacts with the face of cylinder, and bearing capacity is high, and is wear-resistant, makes easyly, is easy to obtain the higher accuracy of manufacture.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.

The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, similar element numbers represents similar element in the accompanying drawing.As mentioned above, the utility model provides a kind of perforating mechanism of stapler, can allocate and mix different types of liquid or lotion increasingly automatedly.
Fig. 1,2,3 is the structural representation of a specific embodiment of perforating mechanism of the utility model stapler, a kind of perforating mechanism of stapler, comprise slide block 7, connecting rod 10, hinge axis 11, support 2, handle 3, bore cutter 4, pressing plate 5, mandrel 12, described support 2 is fixed on the base 1, described slide block 7 can vertically be slidably connected on the described support 10, described hinge axis 11 is connected on the described support 2, the top of described connecting rod 10 and handle 3 are hinged, the bottom of described connecting rod 10 is connected with hinge axis 11, be hinged with mandrel 12 on the described handle 3, the other end of described mandrel 12 and described slide block 7 are hinged; The bottom of described slide block 7 is connected with described pressing plate 5, also is provided with holddown spring 6 between described slide block 7 and the described pressing plate 7.
Be provided with U-shaped chute 25 on the sidewall of described support 2, two of described hinge axis 11 is arranged in described U-shaped chute 25, and moves up and down along described U-shaped chute 25.
Below in conjunction with Fig. 1 to 8, further describe the course of work of the present utility model and operation principle:
The operator drives described handle 3 to pressing down, and described slide block 7 slides on described support 10 straight down, and described connecting rod 10 rotates around described hinge axis 11.The power transmitted is through after the lever amplification of described handle 3, described slide block 7 had larger to the power that presses down.
The bottom of described slide block 7 is equipped with described brill cutter 4, after described brill cutter 4 touches paper, paper is produced shearing force, thereby penetrate paper.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment does.
