Description of the embodiments

The utility model will be further described with reference to the accompanying drawings and specific examples. The technical solutions in the embodiments of the present utility model are clearly and completely described, and the described embodiments are only some embodiments, but not all embodiments, of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model disclosed herein without departing from the scope of the utility model.

As shown in fig. 1-4, the present utility model discloses an embodiment of a fixed tool magazine of an engraving machine, wherein the fixed tool magazine comprises a tool magazine bracket 1, a plurality of tool holders 2 and a plurality of types of tools 3. The tool magazine support 1 is formed by welding a transverse plate 11 and vertical plates 12 at two ends of the transverse plate, and spans and is fixed at the rear end of the upper side of the engraving machine tool body, and the bottom ends of the two vertical plates are fixedly arranged with the machine tool body. The tool holder support 1 is characterized in that a plurality of tool holders 2 are fixedly arranged on the transverse plate 11, the tool holders 2 are made of high-density polyethylene materials, the toughness is high, and the tool holders 2 are uniformly distributed, arranged, installed and fixed on one side of the transverse plate 11 through bolts.
