Shredder with safety mechanism

Abstract

The invention discloses a shredder with a safety mechanism. The shredder comprises a box body. A paper inlet is formed in the box body. An auxiliary hob and a main hob are arranged in the box body. The main hob is connected with a motor. A connecting body is arranged on the auxiliary hob. A first hanging ring is arranged above the connecting body. A second hanging ring is arranged on the top of the box body. A first spring is arranged between the first hanging ring and the second hanging ring. A control bin is arranged in the box body. A pedant body is arranged in the control bin. The pedant body is connected with the connecting body through a belt. A third hanging ring is arranged on the lower portion of the pedant body. A fourth hanging ring is arranged at the bottom of the control bin. A second spring is arranged between the third hanging ring and the fourth hanging ring. A switch portion is arranged on the side wall of the control bin. A push switch is arranged on the lower portion of the switch portion. A pressing block located under the push switch is arranged on the pedant body. Compared with the prior art, the shredder is simple in structure, convenient to manufacture and capable of being easily popularized on a large scale, the personal safety can be guaranteed when impurities such as hair enter the shredder, and accidental occurrence is prevented.

Description

technical field [0001] The invention relates to the field of safety devices of paper shredders, in particular to a paper shredder provided with a safety mechanism. Background technique [0002] A shredder consists of a set of rotating blades, a comb and a drive motor. The paper is fed from the middle of the interlocking blades and is divided into many small pieces of paper to achieve the purpose of confidentiality. The shredding method refers to the shape of paper shredded by a shredder knife after being processed by a shredder. According to the composition of the shredder knife, the existing shredding methods include: crushed, granular, segmental, foamy, strip, and silky. [0003] The structure and working principle of the paper shredder: the paper shredder has two main components, the "paper cutter" and the "electric motor", which are closely connected by belts and gears. The motor drives the belt and gears to transfer energy It is sent to the paper cutter, and the pape...

AI Technical Summary

Problems solved by technology

The paper shredding sensor devices used mainly include electronic induction detectors and mechanical trigger arms. The former is too expensive and expensive; the latter may cause the trigger arm to be stuck by paper, bend, deform or even be broken. Fault

In particular, during the shredding process of the above-mentioned types of shredders, accessories worn by the operator, such as ties, necklaces, and even hair, may enter the paper inlet of the shredder, causing personal safety accidents.
