Problems solved by technology

[0006] In the above-mentioned prior art grinder, since the opening and closing operation parts such as the operating lever and the button are arranged on the upper side of the casing, there may be a problem that fluid is occasionally supplied when the opening and closing operation parts are operated by mistake.
Therefore, when operating the opening and closing operation parts provided on the upper part of the casing for supplying fluid, it is necessary to change hands to hold the casing or temporarily interrupt the processing, so its usability is poor.

Embodiment Construction

[0018] Embodiments of the present invention will be described below with reference to the drawings.

[0019] figure 1 A disc grinder is shown as an example of an electric tool. The front portion ( figure 1 The right side in the center), the gearbox 3 from which the output shaft of the motor protrudes is connected, and the rotating shaft 4, which is rotatably supported in the up and down direction, meshes with the output shaft in the gearbox 3 via the bevel gear, and also makes the rotation The lower end of the shaft 4 protrudes below the gear box 3 and disc-shaped tools 5 such as grinding discs are installed here. Reference numeral 6 denotes a safety cover, which is installed under the gear case 3 and serves to cover the rear of the disc-shaped tool 5 .

[0020] In addition, a handle housing 7 is connected to the rear of the motor housing 2 so that the handle 8 protrudes backward. On the front side of the lower surface of the handle 8, a downward trigger 9 as an operating ...

Abstract

The invention provides an electric tool, which can reduce misoperation of an opening / closing operation component of a valve and increase the operability as well. A disc-type sander (1) has a hose (14) and a valve (12). The valve has an operating lever (13). Supplied water can be sprayed out from a rotating shaft (4) via the hose (14). The lower portion of a handle (8) is extended to form a protection part (10), which surrounds the space below the handle (8) having a trigger (9) and is connected with the handle (8) to form a ring shape. In the protection part (10), a part of the hose (14) penetrates, and the valve (12) is mounted. The operating lever (13) is projected into the lower space.

Description

technical field [0001] The invention relates to an electric tool such as a grinding machine or a grinding machine. The front part of the casing used to accommodate the motor has a rotating shaft driven by the motor to rotate, and tools such as grinding wheels or grinding discs are installed on the rotating shaft. . Background technique [0002] For example, a gear box is connected to the front of the motor housing of the grinding machine for housing the motor, and the gear box supports the rotating shaft and is perpendicular to it, and the rotating shaft is driven to rotate through the bevel gear. . A grinding disc is attached to the end of the rotating shaft protruding from the gear box and used. [0003] Now there is a grinding machine adopting the above-mentioned structure, which has: a fluid supply pipe, which supplies fluids such as water or abrasive from the outside; Close the flow path in the fluid supply tube. The fluid supplied by the fluid supply pipe can be ej...
