Background

The explosion-proof shield of the special police has the functions of bullet prevention, strong light prevention, grenade prevention elastic pieces and the like, and can bear the extrusion of small vehicles. Can resist the knife prick in front of the knife holder. Small caliber bullets and shrapnel are also essentially ineffective at close distances and the blast shield can prevent an adult from climbing. Therefore, in the collision field, in the case that excited people want to rush through a defense line, the policemen in the first row always see that the policemen lift the shield to open a circuit, and the policemen keep the order after the opposite party is deterred.

Although the existing explosion-proof shield used by special police can block the attack from the front, the special police generally needs to hold a gun by one hand and advance the other hand, and the weight of a single shield reaches several kilograms, thus bringing great burden to the movement of the special police. Meanwhile, the shield can only protect the attack from the right front, has poor protection effect on the attack of lateral bullets or stones and the like, and cannot effectively protect the legs of special policemen.

The inventor knows that the existing combined shield can combine a plurality of shields for rotation, but when the ground is uneven, the bottom ends of some shields are tilted, which affects the stability of the whole combined shield, and the combined shield is poor in mobility and easy to overturn.
