Carving knife device with multiple knife heads and capable of realizing free switching

Abstract

The invention discloses a carving knife device with multiple knife heads and capable of realizing free switching. The carving knife device comprises a pen body, a transmission cavity is formed in thepen body, a sliding cavity is formed in the inner wall of the upper end of the transmission cavity in a communicating mode, the sliding cavity is internally provided with a slidable selection switch,and the selection switch comprises a sliding block slidably connected into the sliding cavity, and four rotating grooves formed in the sliding block and being in central symmetry. According to the carving knife device, by rotating a station exchange structure and a unidirectional coupling structure, each time when cutters slide out, a station exchange part rotates by 60 degrees to change the cutters, the different types of cutters can be exchanged only through pressing and leftward moving action of a carver, the cutters do not need to be moved back and forth to be exchanged, focusing again isnot needed even more, continuity of a carving state is maintained, through a downward pressing and rightward moving action, air blowing for clearing wood chippings can be achieved, clearness at the carving position is ensured, and the process quality is ensured.

Description

technical field [0001] The invention relates to the technical field of engraving knives, in particular to a multi-tip and freely switchable engraving knife device. Background technique [0002] A summary of the micro-engraving process requires the use of tools with various edge shapes for different engraving processes. But the traditional microcarving tool is single. The cutting edge parts smelted by steel alloy materials are made into different shapes. When using them, people need to remove their eyes from the micro-sculpture microscope, select the tool and then refocus. [0003] This not only increases the operation steps of the engraver, but also requires a lot of time to find the position again. In addition, the traditional micro-carving process cannot clean up the wood chips on the carving surface in time, resulting in the blocking of the carving observation surface and affecting the quality of the product. The present invention illustrates a device capable of solvin...
