Angle indication amplifying mechanism of electric tool

Abstract

The invention relates to an angle indicating and magnifying mechanism used for an electromotive tool, and the electromotive tool comprises a fixed component and a movable component matched with the fixed component in a rotary manner. The angle indicating and magnifying mechanism is characterized in that the angle indicating and magnifying mechanism is arranged between the fixed component and the movable component, through meshing of different gears in size therein, a gear rim is driven to move; meanwhile, the rotating angle is also magnified, for example, the movable component rotates at 30 degrees relative to the fixed component, while the rotating angle of the gear rim with scale is 2 times of the angle, which is 60 degrees; therefore, 30 degrees of angle is engraved on the scale plate in the range of 60 degrees; therefore, the distance of the identical scale values is greater than the traditional distance, which is convenient for reading, and more precise scales can be also engraved between the identical scale values so that the reading is more accurate.

Description

Technical field [0001] The invention relates to an angle indication amplification mechanism of an electric tool, in particular to an angle indication amplification mechanism applied to an electric miter saw. Background technique [0002] Existing electric miter saws generally include a base and a workbench for placing workpieces. The workbench is rotatably connected to the base. The mechanism includes a saw blade and a motor that drives the saw blade to rotate, and the corner bracket and the saw mechanism rotate around the rotation axis relative to the workbench and rotate left and right to realize oblique cutting. In order to accurately know the angle of left and right inclination, an angle indicating device is often provided, which is composed of a pointer and a dial, wherein if the pointer is set on the corner bracket, the dial is set on the workbench; On the workbench, the dial is set on the corner bracket. When the corner bracket rotates an angle relative to the work...

Problems solved by technology

However, since the mating part between the corner bracket and the workbench is roughly cylindrical, its size is limited, and the corner bracket can be tilted left and right relative to the workbench, and two sets of scales that are tilted left and right need to be displayed on the dial, so set The reading on the dial is too crowded, it is inconvenient to read, and the accuracy of the scale is not enough, which also affects the processing accuracy
