Specific implementation mode

As shown in Figs. 1-5, it includes hollow carbon steel pipe 1 that the utility model electromagnetism, which takes knife device by force, is equipped with inside hollow carbon steel pipe 1 Conducting wire, it is preferred that ensure that safety, the conducting wire are the high current copper conductor with insulating layer.1 left end of hollow carbon steel pipe is installed There are battery 2, switch 3, right end end point to be installed with electromagnet 4, battery 2, switch 3, electromagnet 4 are connected with each other by conducting wire.It is empty The connecting pole 5 vertical with hollow carbon steel pipe 1 is installed on heart carbon steel pipe 1 at the position of electromagnet 4, connecting pole 5 is located at electricity On the right side of magnet 4, major arc shape irony lock 6 is connected on connecting pole 5, which latches and be provided with sawtooth 61 on 6 inner walls. 6 opening of major arc shape irony lock towards it is right it is horizontally disposed after, fixing end 62 is connect with connecting pole 5, band during major arc shape irony latches 6 It is iron to have the material of the right half part of movable end 63, and the material of left-half is carbon steel.

In this way, when electromagnet 4 is powered, the movable end 63 of major arc shape irony lock 6 is solid around it under electromagnetic attraction effect Fixed end and the tie point of connecting pole 5 are rotated clockwise towards electromagnet 4.Major arc shape irony is locked when to avoid 4 no power of electromagnet Button 6 reversely rotates counterclockwise, and limited post 7 is additionally provided on hollow carbon steel pipe 1, which is located at major arc shape irony lock 6 Lower section plays it support, position-limiting action, prevents it from rotating counterclockwise.It is provided on the left end outer surface of hollow carbon steel pipe 1 anti-skidding Rubber layer 8 and handle 9.Preferably, handle 9 can be integrally formed with anti-slip rubber layer 8, can also be made of carbon steel and welded It is fixed on hollow carbon steel pipe 1.On major arc shape irony lock 6 permanent magnet 64 is equipped with close to the position of connecting pole 5.Electricity after energization The outside of magnet 4 is the poles N, and inside is the poles S.Before major arc shape irony lock 6 does not lock, the poles S of permanent magnet 64 are towards electromagnet 4。

After turning on the switch 3, the poles S of electromagnet 4 are repelled each other with the poles S of permanent magnet 64 so that major arc shape irony lock 6 is along suitable Hour hands rotate, and movable end 63 on major arc shape irony lock 6 is sucked in the poles N of electromagnet 4.

After lockking other side's arm with major arc shape irony lock 6, it is clockwise or inverse that driving handle 9 makes entire electromagnetism take knife device by force Hour hands rotate, and the ruffian's arm for being lockable arm also rotates with, and ruffian will actively abandon lethal weapon because of arm pain.

Preferably, to ensure that electromagnetism takes using persistently, for a long time for knife device by force, and use cost is reduced, battery 2 is 24 volts and fills Electric lithium battery.Battery 2 is connect with electromagnet 4 by conducting wire.

Electromagnet 4 is DC electromagnet, and using 24V DC voltages, advantage is will not to burn out (its cylinder because iron core blocks There is no radiating ribs on shape shell), small, reliable operation, permission switching frequency is 120 times/min, and reversing impact is small, uses the longevity Life is longer.

Electromagnet 4 is cylindrical magnechuck, is internally provided with magnetizing coil 11 and iron core 10, magnetizing coil 11 is wound on iron core On 10, the incipient suction force that can be generated reaches 1000 Ns, by magnetic force so as to the irony of suspicion of crime human hand held is firmly sucked Lethal weapon.Switch 3 is push-button switch, and switch is convenient, easy to use, and greatly meeting use urgent, under unsafe condition needs It asks.

Knife arm is held in use, taking electromagnetism by force knife device and firmly waving to ruffian, switch is pressed when touching other side's arm, Magnetic force is generated, while sucking cutter, major arc shape irony lock 6 is also overturn (Fig. 4-7 institutes by magnetic force towards electromagnet 4 Show), and then other side's arm is lockked, then driving handle 9 makes hollow carbon steel pipe 1 rotate, and seizes cutter, reaches and reduces having for injury Beneficial effect.

Embodiment described above is only that preferred embodiments of the present invention are described, not to this practicality Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this The various modifications and improvement that the technical solution of utility model is made should all fall into the protection of the utility model claims book determination In range.
