Embodiment Construction

[0038] Aspects of the invention will now be described more fully. The same reference numbers refer to the same elements throughout. Well-known functions or constructions may not necessarily be 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 hand-held 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, wherein at least one of the blade arrangements 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 . The drive 4 includes, for example, an internal combustion engine 8 and a transmission 10 . The transmission 10 is configured to convert rotational motion caused by the internal combustion engine 8 into linear reciprocating motion of each blade arrangement 6...

Abstract

Herein a blade arrangement (6) for a hand-held power tool (2) is disclosed. The blade arrangement (6) comprises a driving member (16) configured for being driven to reciprocate along a driving direction (18), an elongated cutting blade body (12), and a clamping member (26). The clamping member (26) is configured to engage with the driving member (16) and the elongated cutting blade body (12) so asto press the driving member (16) against the elongated cutting blade body (12) at least partially in the driving direction (18).

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 for the blade arrangement of the hand-held power tool. Background technique [0002] Hand-held power tools are known in the art in which two cutting blade bodies rest against each other in the cutting plane. A hedge trimmer is an example of such a hand-held power tool. Each cutting blade body includes cutting teeth extending transversely relative to the centerline of the cutting blade body. In 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, branches, twigs, grass, etc. are cut. [0003] The cutting teeth of the cutter body dull over time and may need to be refinished or replaced. T...
