Problems solved by technology

[0007] However, especially in the case of cutting, although sometimes it is desirable to hold the cutting tool tightly with both hands and move it, however, the advantages of small size and light weight will be damaged, or due to the Because it is a small and light cutting tool, it is considered unnecessary (installation of an auxiliary handle), etc., and there is no cutting tool with an auxiliary handle in the prior art

Embodiment Construction

[0101] Next refer to Figure 1-20 A specific embodiment of the present invention will be described. Figure 1~4 Shown is an overall view of the portable cutting tool 1 of this embodiment. The cutting tool 1 is called a portable circular saw, and is a relatively small and light cutting machine. The user can hold the cutting tool 1 and move it on the workpiece W to perform cutting. Firstly, its overall structure will be roughly explained below.

[0102] This cutting tool 1 has a plate-shaped base 2 for being placed on the upper surface of a workpiece W to be cut, and a tool body 10 is supported on the upper surface of the base 2 . exist figure 1 , the user is located on the left side of the cutting tool 1, by turning the cutting tool 1 to figure 1 middle right ( figure 1 The direction shown by the hollow arrow (A)) moves to enable cutting. In the following description, unless otherwise specified, as shown in each figure, the direction in which the cutting process is perfor...

Abstract

The present invention relates to a cutting tool having a relatively small size and a relatively lightweight, generally named as a portable circular saw, comprising a bar-like handle backwards extending from a tool main body. In the prior technology, the movement operation is performed by gripping a handle by one hand not by two hands. In the premise of keeping the advantages of the portable circular saw that: small size and light weight, the movement operation is performed by two-hands gripping. A motor housing (43) of an electric motor (40) extending to the side surface relative to the handle (20) is formed into a vertical long flat cylinder shape, so as to faciliate gripping, therefore the electric motor (40) also has the function of an auxiliary handle.

Description

technical field [0001] The present invention relates to a portable cutting tool, for example known as a portable circular saw. Background technique [0002] This cutting tool has a structure in which a tool body is supported on an upper surface of a base placed on a workpiece to be cut, and the tool body has a circular rotary cutter driven by an electric motor to rotate. When cutting, the lower part of the rotary cutter protruding to the side of the lower surface of the base cuts into the workpiece while moving the tool body in the direction of cutting progress so that the cutting process can be performed. Therefore, a handle portion is provided on the tool body for the user to grasp so as to operate the tool body to move in the cutting direction. [0003] When the cutting tool is designed to be small and lightweight, the conventional handle has, for example, a rod-shaped structure with ends (the rear end being a free end) disclosed in the following patent documents. The u...
