Although the refulgence of the shield in military use is no longer present today, the shield will glow new lives in the modern police field. Under the large atmosphere that the world situation tends to be peaceful at present, the possibility of large-scale wars is not high, and the individual criminal activities in the country are frequently happened, so the personal safety problem faced by the police officer is the first time, and at the moment, the police shield plays a very important role in the field of single-police protection.

The shield used in the field of modern police is called as an effective tool for embodying police civilization law enforcement in the face of harassing crowds and low-intensity conflicts in police law enforcement.

When being attacked, the modern police shield is mainly attacked by the following attack modes:

1. attack by mechanical objects such as sticks and cutters: when criminals practice such attacks, the criminals typically hold sticks, knives, etc. to flap, chop, or poke the shield. The shield surface in the shield in the prior art is usually a plane shield surface and a circular arc shield surface. If the front surface of the shield is a plane, when the shield is attacked, the force of the stick can be mostly supported by the shield and conducted to the arms of law enforcement officers, so that the shield is easily injured due to excessive force, and in a more serious case, the shield can be out of hand and lose protection; if the shield openly is the arc surface, when the shield suffered this type of attack, the stick can slide along the shield face, can the certain impact force of effectual uninstallation, nevertheless because the shield surface does not have the guide effect, so the stick can be irregular slide along the shield surface, is unfavorable for law enforcement personnel to judge how to counterattack and pay for the instrument on the one hand, and on the other hand, also can cause the personnel's injury of law enforcement in coordination to injure. In the prior art, when the shield is attacked by knife cutting, the shield head of the shield is generally provided with the anti-cutting strip, so that the shield can be prevented from being damaged when being longitudinally cut, but the mode of only arranging the anti-cutting strip at the shield head cannot protect transverse or oblique cutting, the protection range of the shield is smaller, and the shield cannot be protected positively.
