Safe switching mechanism of shredder

Abstract

The invention relates to a safe switching mechanism of a shredder, comprising a safety switch which is connected in series with a main power switch of the shredder and has two states of switching off and switching on. The safe switching mechanism also comprises a deflector rod, a first triggering assembly connected to a hopper of the shredder and a second triggering assembly connected to a tool rest and an end cover of the shredder, wherein the first triggering assembly and the second triggering assembly can be respectively matched and connected with the deflector rod; when the first triggering assembly and the second triggering assembly are matched and connected with the deflector rod simultaneously, the deflector rod triggers the safety switch so that the safety switch is in a switching on state; and when the first triggering assembly or the second triggering assembly is separated from the deflector rod, the deflector rod is separated from the safety switch so that the safety switch is in a switching off state, thus, when both the hopper and the end cover or either the hopper or the end cover are / is not installed in place, the deflector rod is failed to trigger the safety switch, thereby enabling the safety switch to be in the switching off state and ensuring the personal safety of users in many aspects.

Description

technical field [0001] The invention relates to a safety switch mechanism of a shredder. Background technique [0002] Branch shredders are usually used to chop branches, branches, etc. in the garden so as to collect and clean up the chopped branches and branches. The wood chipper generally includes a main body and a hopper positioned below the main body. The top of the main body is provided with a feed port, and a motor, a transmission device and a cutting tool are installed inside it, wherein the cutting tool is installed in a knife seat, and the main body is provided with an end cover covering the knife seat. The cover is detachable over the knife block. In this way, when the cutting tool needs to be maintained or replaced during use, the end cover can be disassembled from the knife seat to expose the cutting tool for easy maintenance or replacement. This requires a safety protection device. When the cover is disassembled to expose the cutting tool, it prevents acciden...

Problems solved by technology

In this way, when the hopper is disassembled from the main body or is not installed in place, the cutting tool can be accidentally touched from the bottom of the main body, so there is a certain potential safety hazard. Therefore, for this kind of hopper that can be disassembled from the main body In terms of wood chippers, it is necessary to provide an improved safety switch mechanism, which can not only provide safety protection for the user when the end cap is not installed in place, but also provide safety protection for the user when the hopper is not installed in place.
