Abstract

The utility model discloses a paper shredder with a paper pressing device, which comprises a trash can, wherein a top cap is arranged at the upper end of the trash can, and the paper pressing device capable of moving along the inner wall of the trash can vertically is arranged in the top cap. Paper containing capacity of the trash can is increased while the problem that the trash cans in the existing market are low in paper containing capacity is solved, thereby own value of the paper shredder is increased greatly.

Description

A kind of shredder that has paper pressing device

Technical field

The utility model relates to the shredder technical field, especially relates to a kind of shredder that has paper pressing device.

Background technology

Shredder is office's equipment commonly used, by people are known, but present shredder; Dustbin is connected with shredder, behind the broken at ordinary times intact paper of consumer, because a scrap of paper is in bulk state; Be easy to dustbin is filled, could follow-up work and just need this moment dustbin is soared, increased the packing and the cost of transportation of a scrap of paper to the consumer; Increased office cost, therefore be necessary to improve.

The utility model content

To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of shredder that has paper pressing device, can a scrap of paper compacting that be in bulk state in the dustbin have been increased the capacity of dustbin greatly.

To achieve these goals; The technical scheme that the utility model adopted is: a kind of shredder that has paper pressing device; Comprise dustbin, said dustbin upper end is provided with housing, and being provided with paper pressing device and paper pressing device in the said upper cover can move up and down along the dustbin inwall.

Wherein, Said paper pressing device is made up of closed shell and spring, and said closed shell is made up of loam cake, set of knives and lower cover, and said set of knives places in the cavity of lower cover and loam cake formation; Said spring is curved, and both ends of the spring is fixedly connected with last housing after passing loam cake.

Further, be covered with the spring shield suitable with its shape on the said spring, both ends of the spring is fixedly connected with last housing after stretching out spring shield, and said spring shield two ends are equipped with positive stop lug boss.

Further, said loam cake two ends all are shaped on two through holes, and said both ends of the spring is fixedly connected with last housing after passing through hole.

After adopting said structure, the utility model is compared the paper stack capacity that has not only increased dustbin greatly with prior art, but also has solved the few problem of rubbish barreled paper amount in the market, thereby increases the value of device itself greatly.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Embodiment, see that Fig. 1 is to shown in Figure 3:

A kind of shredder that has paper pressing device comprises dustbin 1, and last housing 3 places dustbin 1 top and is supported, and being provided with paper pressing device and paper pressing device in the upper cover 3 can move up and down along dustbin 1 inwall.

Above-mentioned paper pressing device is made up of closed shell 2 and spring 7, and closed shell 2 is made up of loam cake 4, set of knives 5 and lower cover 6, and set of knives 5 places in the cavity of lower cover 6 and loam cake 4 formations; Spring 7 is curved, is covered with the spring shield 8 suitable with its shape on the spring 7, can protect spring 7; Spring shield 8 is stretched out at spring 7 two ends, and loam cake 4 two ends all are shaped on two through holes 9, and spring 7 two ends are passed through hole 9 backs and are fixedly connected with last housing 3; Spring shield 8 two ends are equipped with positive stop lug boss 10

Operation principle: when give through paper inlet 11 put into waste paper and start functional switch 12 in the shredder waste paper is smashed after; Shredded paper in the dustbin 1 can get more and more; After exerting pressure to this moment closed shell 2, spring 7 is just upheld and is elongated, and then forms platen action (as shown in Figure 2); Spring 7 will set back when cancellation exerts pressure for closed shell 2, and the platen action is accomplished, and returns to normal operating conditions (as shown in Figure 3).

Shredder is widely-used at present, and other structure is identical with prior art with principle, repeats no more here.

The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
