The four-piece set includes a knife-suction tool, a choking instrument, a self-defense device and a capturing device. It took the inventor 4 months to develop the four-piece set and the inventor hopes that the set can be popularized with campus security units.

On July 22 in Gucheng Village, Tongzhou District, Qi Haijun, a qualified worker from the Beijing No.8 Middle School, demonstrated a four-piece toolset, including a knife-suction tool, a choking instrument, a self-defense device and a capturing device, which he had invented for campus security.

There is a pair of pliers containing 8 powerful magnets on the end of a long pole. The pliers are open when not in use. If a criminal wielding a knife approaches, the user of the pole can flick a switch on the bottom of the pole and the pliers will immediately close and the magnets will attract the knife. The criminal will not be able to get his knife back.

There is a retractable iron ring on the end of a steel pipe. When a criminal approaches, the user of the steel pipe can put the ring around the mobster’s neck and then flick a switch on the bottom of the pipe. The ring will immediately tighten. It can also be used to restrict the movements of the criminal’s arms.

It is like a pair of combination slip-joint pliers which can be opened and closed freely. It consists of two crossed steel pipes with ridged front-ends. The user can use the crossed steel pipes to capture a criminal who is approaching. The user can also use this device to discharge pepper spray.
