Embodiment Construction

[0038] Aspects of the invention will now be described more fully. Like reference numerals refer to like elements throughout. Well-known functions or constructions are not necessarily described in detail for brevity and / or clarity.

[0039] figure 1 A hand-held power tool 2 according to an embodiment is shown. According to these embodiments, the handheld power tool is a hedge trimmer 2 . However, according to alternative embodiments, the hand-held power tool 2 may be any hand-held power tool comprising a pair of blade arrangements, at least one of which is a blade arrangement as discussed herein.

[0040] The hand-held power tool 2 includes a drive unit 4 and a pair of blade units 6 . Drive 4 includes, for example, an internal combustion engine 8 and a transmission 10 . The transmission 10 is configured for converting the rotational motion caused by the internal combustion engine 8 into a linear reciprocating motion of each blade arrangement 6 of a pair of blade arrangemen...

Abstract

The invention discloses a blade device (6) for a hand-held power tool (2). The blade arrangement (6) includes a drive member (16) configured to be driven to reciprocate along a drive direction (18); an elongated cutting body (12); and a clamping member (26). The clamping member (26) is configured to engage the drive member (16) and the elongated cutting body (12) to at least partially press the drive member (16) against the elongated cutting body (12) in the drive direction (18). on the cutter body (12).

Description

technical field [0001] The present invention relates to a blade arrangement for a hand-held power tool, to a hand-held power tool comprising the blade arrangement, and to a clamping member of the blade arrangement for a hand-held power tool. Background technique [0002] Hand-held power tools in which two cutter bodies abut each other in a cutting plane are known in the art. A hedge trimmer is an example of such a handheld power tool. Each cutter body includes cutting teeth extending transversely with respect to the centerline of the cutter body. During operation of the hand-held power tool, the cutter bodies are reciprocated in opposite directions, such that the gaps between the cutting teeth of the two cutter bodies are alternately closed and opened. Thus, in the cutting plane between the cutting teeth, twigs, twigs, grass etc. are cut. [0003] The cutting teeth of the cutter body become dull over time and may need to be reground or replaced. Therefore, it is desirabl...
