Description
Technical Field
The invention belongs to the technical field of paper shredders, and particularly relates to a paper shredder.
Background
The existing paper shredder generally comprises a box body, a bar-shaped opening used for paper entering is formed in the box body, two sides below the bar-shaped opening are respectively provided with a rotating shaft, a blade is arranged on the rotating shaft, a motor used for driving the rotating shaft to rotate is arranged in the box body, a sensing switch used for controlling the motor to rotate is arranged on the side of the bar-shaped opening, when the paper stretches into the opening to touch the sensing switch, the motor drives the rotating shaft to rotate, so that the paper is rolled into the box body and shredded. Since the strip-shaped opening is not provided with the foreign matter detection device, if foreign matters enter the strip-shaped opening, the foreign matters can be drawn into the rotating shaft by the rotating shaft to be chopped, so that the clothes can be chopped and hardly stopped and pulled out if a user carelessly puts corners of the clothes or other things on the opening by mistake, and certain danger exists if the corners of the clothes are drawn into the openings, the corners of the clothes can not be cut off quickly and cannot be pulled out.
Disclosure of Invention
The invention provides a paper shredder aiming at the defects of the prior art, which can quickly separate a rotating shaft from transmission when foreign matters are drawn in, tear out the foreign matters, prevent danger and prevent the inserted foreign matters from being shredded.
In order to solve the technical problem, the invention is solved by the following technical scheme: the paper shredder comprises a box body, wherein a strip-shaped opening for placing paper is arranged on the box body, rotating shafts are arranged on two sides in the strip-shaped opening, blades are arranged on the rotating shafts, a motor for driving the rotating shafts to rotate is further arranged in the box body, the motor and the rotating shafts are in gear transmission, the box body comprises an upper box body and a 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 are in matched movement, the lower box body is rotatably connected with two pairs of connecting rods, the lengths of the connecting rods are the same, the other ends of the connecting rods are connected with a sliding block, a linear sliding groove is arranged on the upper box body, the sliding block is arranged in the sliding groove, one rotating shaft is rotatably arranged on each pair of connecting rods, an elastic body is arranged between the upper box body, the upper end of the elastic body abuts against the upper box body, an output shaft of the motor is provided with a first gear, two rotating shafts are respectively provided with a second gear and a third gear, the upper box body is rotatably provided with a fourth gear, two sides of the fourth gear are meshed with the first gear and the second gear, and 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. When the paper shredder is used, if foreign matters enter the strip-shaped opening, the upper box body can be pressed downwards to enable the connecting rod to rotate, so that the rotating shaft is separated from power, the rotating shaft stops rotating and cutting, and the inserted foreign matters are prevented from being shredded.
Compared with the prior art, the invention has the following beneficial effects: when the paper shredder is used, if foreign matters enter the strip-shaped opening, the upper box body can be pressed downwards to enable the connecting rod to rotate, so that the rotating shaft is separated from power, the rotating shaft stops rotating and cutting, and the inserted foreign matters are prevented from being shredded.
