Abstract

The invention discloses a guard strip plate locking device, which comprises a workbench, a guard strip plate and locking screws, wherein the guard strip plate is arranged in a groove of the workbench, each vertex angle of the guard strip plate is provided with a circular hole, each locking screw penetrates through a circular hole and extends to a position below the workbench, and the tail end of each locking screw is provided with a through hole for inserting an elastic pin; and in a locking state, the elastic pin is inserted into the through hole, and one end of the elastic pin exceeds the edge of the groove of the workbench, so that the guard strip plate is clamped on the workbench. The device overcomes the prejudice of those skilled in the prior art; quickness and convenience of assembly and disassembly of the guard strip plate are considered, and the safety of the guard strip plate is more stressed; the workbench, the guard strip plate, the locking screws and the elastic pins are used as locking components and mutually matched; the positions of the elastic pins are adjusted by using a tool to effectively lock the guard strip plate, so that the safety performance can be greatly improved; and moreover, because excessive locking pieces are not increased, the guard strip plate is very convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to a guard strip of an electric tool, in particular to a locking device for the guard strip. Background technique [0002] At present, table saws, woodworking saws, miter saws, compound saws, etc. are common electric cutting tools and are widely used in the field of machinery manufacturing. These electric cutting tools all include a saw blade. Usually, a part of the saw blade is located in the workbench, while the other part is exposed from the workbench so as to cut wood, plastic and other articles. In order to protect the saw blade and ensure safety, guard strips are installed on the workbenches of the existing electric cutting tools. [0003] In the prior art, when installing the guard strips on the workbench, people first consider the convenience and rapidity of installation and disassembly. The existing guard strips are usually embedded in the groove of the workbench and installed by pressing or pressing; or they are instal...
