Desktop tool

Abstract

The invention discloses a desktop tool. The desktop tool comprises a workbench and a saw mechanism which is connected with the workbench, wherein the saw mechanism comprises a motor, a saw blade and a drive mechanism; the saw blade is driven to rotate by the motor; the drive mechanism comprises a first gear, a second gear, a third gear, a fourth gear and an intermediate shaft, wherein the first gear is arranged on the shaft of the motor; the second gear is engaged with the first gear; the third gear is arranged on the shaft of the saw blade; the fourth gear is engaged with the third gear; and the projection of the first gear and the projection of the third gear on a base plane are positioned on the same side of the axial line of the intermediate shaft. In such a way, the shell of the motor is intersected with the plane of the saw blade, so that the motor and the shell of the motor are closer to the saw blade; the overall width of the shell of the motor and a fixed protective cover is reduced; and interference between the shell of the motor and a guardrail or a base is prevented. Moreover, the motor and the shell of the motor are closer to the saw blade, so that the structure is more compact; therefore, a better field of view is provided for an operator.

Description

technical field [0001] The invention relates to a table tool, especially a miter saw. Background technique [0002] A bench tool is a machine that uses a motor to drive a saw blade to rotate, thereby cutting a workpiece, and generally includes a miter saw, a table saw, and the like. A traditional miter saw includes a base for placing workpieces, a support frame fitted on the base, and a saw mechanism fitted on the support frame, wherein the support frame drives the saw mechanism to perform oblique cutting relative to the vertical position, and due to The motor in the traditional miter saw is set horizontally, so that the support frame can only tilt to one side relative to the vertical position, otherwise the motor housing will interfere with the guardrail or base, so the traditional miter saw can only tilt to the left To cut the workpiece, the maximum inclination angle is about 45 degrees. However, since this kind of miter saw can only realize one-way oblique cutting to th...

AI Technical Summary

Problems solved by technology

The motor is arranged on the right side of the saw blade, which will cover part of the workpiece on the right side of the saw blade, thereby affecting the operator's observation field of view; and because the motor in the saw mechanism has the largest weight, the center of gravity of the entire saw mechanism is close to the motor, and In this miter saw, the motor is arranged close to the saw blade shaft, so that the center of gravity of the saw mechanism is closer to the front, that is to say, the vertical distance between the center of gravity of the saw mechanism and the pivot axis of the saw mechanism is farther, so that the force arm increases, which affects the Reset of saw mechanism
