Embodiment Construction

[0028] figure 1 A power saw 1 is shown schematically as an example of a hand-held power tool. However, the hand-held power tool can also be other hand-held power tools, such as cutters and the like. The power saw 1 has a handle unit 2 and a motor unit 16 separated from the handle unit 2 by a vibration gap 30 . exist figure 1In , for better visibility, the motor unit 16 is shown with dashed lines, while the handle unit 2 is shown with solid lines. The handle unit 2 comprises a rear handle 6 and a handle bow 7 . The handle bow 7 overlaps the housing 4 of the power saw 1 . The handle unit 2 includes a fuel tank 3 which is arranged adjacent to a rear handle 6 . Furthermore, the handle unit 2 has a bridge 5 extending in the longitudinal direction of the power saw 1 . Anti-vibration elements 18 and 19 are held on the bridge 5 . Advantageously, two anti-vibration elements 18 and two anti-vibration elements 19 are provided, which are respectively arranged on both sides of the b...

Abstract

The invention relates to a handheld work instrument, which includes a motor unit (16) with a drive motor (11) and a handle unit (2). The handle unit (2) and the motor unit (16) are vibrationally separated by at least one anti-vibration element (17, 18, 19, 20). The anti-vibration element (20) is fixed to a first part of the handle unit (2) via a holding device (51) and to a second part of the motor unit (16) via a holding element (36). A breaking portion is provided in the connecting portion between the first component and the second component. In order to avoid damage to other parts of the work tool in the event of overload, it is provided that the breaking point is formed on the third part, and the third part can be replaced independently of the first part and the second part, and the first part The connection between the component and the second component via the anti-vibration element has minimum strength at the breaking point.

Description

technical field [0001] The invention relates to a hand-held power tool of the type specified in the preamble of claim 1 . Background technique [0002] DE 10 2007 022 115 A1 discloses a hand-held power tool, namely a power saw, in which a handle unit and a motor unit are vibrationally separated from one another by a plurality of vibration-damping elements. Some anti-vibration elements have helical springs, in the ends of which are fastened plugs for fastening to the motor unit and the handle unit. [0003] From DE 101 24 621 A1 a working medium tank for a hand-held power tool is known, in which a damping element is plugged onto a bolt arranged on the working medium tank. In order to avoid damage to the working medium tank when the bolt breaks, a breaking point is provided between the bolt and the wall of the working medium tank. However, the entire operating medium tank must be replaced if the bolt is damaged. Contents of the invention [0004] The object of the inventi...
