Embodiment Construction

[0055] figure 1 shows a particularly small and compact battery-powered grinding machine 10, its housing 12 is shown openly by removing the right housing shell 16 and the line of sight can freely penetrate into the interior or shell provided in the housing 12 On the components in the body shell 14 that will be described in detail below.

[0056] The housing 12 is formed from two half shells 14 , 16 which can join together in a central plane 15 in a sealingly supportive manner. For this reason five screws pass through some holes in the upper half shell 16 ( figure 2 ) are screwed into the five screw sleeves 40, 41, 42, 43, 44 of the lower half-shell 14 in order to fix the two to each other. The upper region of the housing 12 forms a curved handle region which can also be comfortably held by small hands.

[0057] Below the viewing direction, the housing 12 carries an iron-like, triangular-shaped grinding disc 18 whose disc tip 19 points to the right in the viewing direction ...

Abstract

The invention relates to a handheld grinding machine, in particular to the grinding machine which is provided with storage batteries to supply electricity. The grinding machine is provided with a shell body (12), which can hold an electromotor (24) for driving a grinding disc (18); the grinding disc (18) is arranged on the bottom side of the shell body. Aiming at being smaller, lighter, convenient for operation, and being produced advantageously in cost, the invention provides a component which is used for turning on and turning off a switch button (34) of an electromotor (24), and is constructed into plate spring shaped and can be operated crookedly.

Description

technical field [0001] The invention relates to a hand-held grinding machine tool, in particular a battery-powered grinding machine, having a housing that houses an electric motor for driving the grinding disc and on the bottom side of the housing a Grinding disc. Background technique [0002] Battery-powered hand-held grinding tools are already known, which generally have a plurality of relatively heavy nickel-cadmium (NiCd) batteries as energy stores and have the same mechanical Components such as identical drive gears, fan impellers and balancing masses and eccentric drives for unbalance compensation or switches and switch operating components. [0003] Disadvantages of this known hand-held power tool are its bulky overall dimensions and its high weight due to its large and heavy components. This has a negative impact on the ergonomics, ease of operation and production costs of known battery-operated hand-held grinding tools. Contents of the invention [0004] Acc...
