Paper shredder

Abstract

The invention discloses a paper shredder, a paper feeding inductor of which is provided with a touch rod, an inductive switch and an amplifying touch rod, wherein the inductive switch is fixed on a paper shredding mechanism, the middle of the touch rod is pivoted to the paper shedding mechanism, the first end of the touch rod extends into a paper feeding channel, the middle of the amplifying touch rod is pivoted to the paper shredding mechanism, and the second end of the touch rod is overlapped with the first end of the amplifying touch rod; when the touch rod rotates due to the support of paper inserted into the paper feeding channel, the touch rod drives the second end of the amplifying touch rod to touch the inductive switch; and when no paper is inserted in the paper feeding channel, the touch rod and the amplifying touch rod are kept in a reset state and the second end of the amplifying touch rod does not touch the inductive switch, the sensitivity, the reliability and the stability of the action of the paper feeding inductor are increased, and a high-precision inductive switch does not need to be configured for the paper feeding inductor, thus the production cost of the paper shredder is lowered, and the inductive switch is not easy to damage and has a long service life.

Description

[0003] In the prior art, a paper shredder is provided with a paper feeding passage and a paper feeding sensing device, a paper shredding cutter set is arranged under the paper feeding passage, the paper feeding sensing device is arranged at the side of the paper feeding passage, and the paper feeding sensing device is used for Sensing whether there is paper inserted into the paper feeding channel, the paper feeding sensing device is provided with a touch lever, a sensor switch and an enlarged touch lever, the sensor switch is fixed to the paper shredding mechanism, the middle part of the touch lever is pivotally connected to the paper shredding mechanism, and the first part of the touch lever One end protrudes into the paper feeding channel, the second end of the trigger rod is against the sensor switch, and the paper inserted into the paper feeding channel is pushed against the first end of the trigger rod to drive the trigger rod to rotate around its pivot joint, and then Make the second end of the touch lever touch the induction switch, but the paper shredder requires the induction device to have high stability and high sensitivity. Therefore, the induction device needs to be equipped with a high-precision induction switch to meet the requirements of the induction device of the paper shredder. Requirements for use, and the high-precision induction switch has a high cost and is easily damaged. The service life of the high-precision induction switch is short, which affects the quality of the shredder. Therefore, there is a need for improvement in the shredder of the prior art.
