Abstract

Reciprocating saw (1) for machining a workpiece, in particular a mineral or metallic workpiece, comprising a drive (20) and a stroke rod (60) having a first stroke rod end (63), a second stroke rod end (68) and a drive point (69). Furthermore, a first articulated rod (40) having a pivot point (42) and a connecting point (44) and a second articulated rod (50) having a first pivot point (52) and a second pivot point (54) are provided, wherein the pivot point (42) of the first articulated rod (40) can be rotatably connected to the drive point (69) of the stroke rod (60), and the connecting point (44) of the first articulated rod (40) can be connected to the drive (20) for conjoint rotation therewith by means of a connecting device (70), and wherein the drive (20) can be positioned at least partially in a drive housing.

Description

technical field [0001] The invention relates to a reciprocating saw for machining workpieces, in particular mineral or metallic materials ( ). The reciprocating saw includes a driver and a reciprocating rod having a first reciprocating rod end, a second reciprocating rod end, and a drive point. Background technique [0002] Reciprocating saws of the aforementioned type are basically known and are mainly provided in machines for sanitary, heating and climate technology, carpentry and building carpentry applications. Reciprocating saws are also known as reciprocating saws, lift saws, or tiger saws. The most common applications of such saws are demolition of old structural members and separation of pipes, conduits or the like. There are specific guides for separating the metal tubes which facilitate straight cuts. Different materials can be processed according to the choice and characteristics of the saw blade. Saw blade options are used for metal, wood, plastic, blank cu...
