Description

technical field [0001] The subject of the invention is a knife with a telescopic blade ("telescopic cutting knife") adapted to work in special situations, such as working in harsh environments, where a direct grasp of the tool is not possible. Background technique [0002] Working in harsh environments is accomplished with a glove box, where the operator inserts his (or her) arms into a wall with a master and slave arm that mimics the operator's motion on the other side of the protective wall. remote control machine. The operator cannot achieve complete freedom of movement and does not feel the same sensations as he would feel under normal working conditions, thus reducing dexterity. As a result, many tasks become difficult to perform, wherein, in the application considered here with regard to telescoping knives, the actions of opening and retracting the blade, and locking the blade at a selected position are usually accomplished by manipulating a small mechanism on the kni...

AI Technical Summary

Problems solved by technology

and having to grip these knives differently depending on whether someone is moving the blade or adjusting it can lead to an overly complicated process

Finally, these clumsy movements likely increase the risk of accidents when the blades are opened
