Problems solved by technology

And because there is no foreign matter detection device on the bar-shaped opening, if foreign matter enters the bar-shaped opening, it will be drawn into the rotating shaft for shredding, so if the user accidentally puts the corner of the clothes or other things by mistake It will be very difficult to stop and pull out when it reaches the opening. If the corner of the clothes is caught, it will be dangerous because the corner of the clothes cannot be cut off quickly and cannot be pulled out.

The paper shredder comprises a box body; the box body is provided with a strip-shaped opening for charging paper; the box body comprises an upper box body anda lower box body; the lower part of the upper box body is opened; the upper part of the lower box body is opened; the upper box body and the lower box body move in a manner of being matched with eachother; the lower box body is rotationally connected with two pairs of connecting rods; the other end of each connecting rod is connected with a slider; the upper box body is provided with linear sliding chutes; each slider is arranged inside the corresponding sliding chute; each pair of connecting rods is rotationally provided with one rotating shaft; an elastic body is arranged between the upperbox body and the lower box body; an output shaft of a motor is provided with a first gear; the two rotating shafts are separately provided with a second gear and a third gear; the upper box body is rotationally provided with a fourth gear; the two sides of the fourth gear are meshed with the first gear and the second gear; the first gear is meshed with the third gear; when the upper box body is pressed downwards, the fourth gear is separated from the second gear, and the first gear is separated from the third gear. The paper shredder disclosed by the invention can make each rotating shaft bereleased from transmission quickly when a foreign material is entangled into the paper shredder.

Description

technical field [0001] The invention belongs to the technical field of paper shredders, in particular to paper shredders. Background technique [0002] Existing paper shredders generally include a box body, which is provided with a strip-shaped opening for paper to enter, and a rotating shaft is respectively arranged on both sides below the strip-shaped opening, and a blade is arranged on the rotating shaft. There is a motor used to drive the rotating shaft to rotate, and an induction switch to control the rotation of the motor is provided on the side of the strip-shaped opening. When the paper is inserted into the opening and the induction switch is touched, the motor drives the rotating shaft to roll the paper into the box and shred it . And because there is no foreign matter detection device on the bar-shaped opening, if foreign matter enters the bar-shaped opening, it will be drawn into the rotating shaft for shredding, so if the user accidentally puts the corner of the...
