Disclosed is an electric mitre saw, comprising a base (1), a work bench (2), a saw mechanism, and a swing arm (4), wherein a plurality of layers of slide rails (5, 11) extending in a horizontal direction are provided on the swing arm (4), with the plurality of layers of slide rails (5, 11) being able to slide horizontally relative to each other by means of a slide block (6), a rotary shaft (10) is provided on one layer of the slide rails (11) farthest away from the swing arm (4), and the saw mechanism is rotatably connected to the rotary shaft (10). By means of the arrangement of the plurality of layers of slide rails (5, 11), the length of each layer of slide rails is relatively short, the manufacturing difficulty is reduced, there is a saving in the working space of the mitre saw, and the packaging volume is reduced. When one layer of slide rails (5, 11) is respectively arranged at both sides of a saw blade (15), the end parts of two slide rails of each layer of slide rails (5, 11) are able to be connected by a connecting seat (8, 14), thus facilitating the improvement of parallelism of the two slide rails (5, 11), and providing a greater cutting travel. A gripping space is also formed between the two layers of slide rails (5, 11), such that observation during cutting is convenient. |
