Problems solved by technology

The defect of the safety lever of this blade type lock cylinder is that when the technology is opened, the technical opener can use a tool to move the blade on the outside of the blade lock, and make the end of the safety rod close to the outside move down and snap into the upper end of the blade. In the blade groove, move the blades on the outside of the blade lock one by one to make the inner end of the bumper move down and finally achieve the purpose of technical opening. The inclination of the bumper during the technical opening process will make the technical opening more convenient. Simple, this seriously affects the anti-theft performance of the blade lock
