Embodiment Construction

[0044] See attached Figure 1-7 , the invention discloses an electric tool. In this preferred embodiment, the electric tool is an electric circular saw, including a circular saw blade as a rotatable tool 2 , a motor 4 , a shaft 5 , a transmission device 6 , a first handle 7 and a second handle 37 . The tool 2 defines a tool axis X, the saw blade guard or tool housing 3 accommodates the supporting tool 2 rotatably about the tool axis X, and the motor 4 has a motor housing 4 a and a shaft 5 . The shaft 5 defines a longitudinal axis Y, which is arranged parallel to the tool axis X. The transmission 6 , comprising a gear system 34 connecting the shaft 5 to the tool 2 , transmits energy from the motor 4 to the tool 2 . The first handle 7 and the second handle 37 are U-shaped, the operator holds the two handles to move the power tool 1, each handle is firmly attached to the tool housing 3, and the switch device 8 (including the safety button) is arranged on the handle 7, connecte...

Abstract

An electric tool (1) is provided, particularly an electric circular saw which comprises a tool (2) with a tool axis (X), a tool housing (3) for the store and the support of the tool (2) rotating around the tool axis (X), a motor (4) with a shaft (5) for defining a longitudinal axis (Y), a gearing device (6) for connecting the shaft (5) with the tool (2), and at least one handle (7,37) for supporting the electric tool (1) and provided thereon with a power switch (8) eclectically connected with the motor (4). The motor (4), the handle (7, 37) and the power switch (8) are firmly interconnected to form an unit body (9) that facilities the electric tool to be positioned in a comfortable operating position. The unit body (9) is connected on tool housing (3) and rotates around the longitudinal axis (Y) relative to the tool housing (3) or pivots around the tool axis (X) in parallel to the longitudinal axis (Y).

Description

technical field [0001] The invention relates to a saw electric tool, in particular to an electric circular saw tool with a handle device. Background technique [0002] Typically, a power tool has a main body in which is located a motor with a shaft slowed down by a gear box and connected to the rotary tool. Power tools with circular blades, such as circular saws or bench grinders, are partially covered to protect the user during operation. The body typically includes a handle by which the operator holds and drives the power tool. In most cases, the body is supported on the workpiece by a base plate. The body of the circular saw can be adjusted relative to the base plate, thereby changing the cutting depth of the saw blade. [0003] Currently, almost all power tools on the market have a handle and a rotary tool integral to the main body. Similar machine tools have the disadvantage when operating on vertical, inclined or very long workpieces, the operator has to move a con...
