Abstract

The invention relates to a guiding locking device with flexible long arm furnishing cutter. The guiding locking device is formed by a guiding element that mounted in the muffled flexible inner and outer tubes and a locking element fixed at the end of outer tube. The cutter comprises a flexible handle rod formed by muffled flexible inner and outer tubes and a guiding element mounted on the inner and outer tubes, and a locking element fixed at the end of outer tube. The front end of inner tube is arranged with the cutting element while the back end of outer tube is arranged with a controlling handle of cutter. The invention has simple structure and low cost, while the clamper and contactor of handle can improve the application.

Description
