Detailed Embodiment

[0019] Please refer to Figures 1 - 5, An offensive and defensive all-purpose arm shield, including a shield body 1. A protective groove 2 is provided on the surface of the shield body 1. An installation groove 4 and a ventilation groove 6 are provided inside the shield body 1. A power supply structure 3 and a controller 5 are fixed on the surface of the installation groove 4. An insulating copper wire 7 is provided on the inner wall of the ventilation groove 6. One end of the insulating copper wire 7 is fixed with an electrode 8. The insulating copper wire 7 and the electrode 8 both penetrate the shield body 1. A shock-absorbing plate 9 is embedded and fixed inside the shield body 1. A liquid storage tank 10 is fixed on the surface of the shield body 1. A delivery pump 11 is communicated with the surface of the liquid storage tank 10. A delivery pipe 12 is communicated with the surface of the delivery pump 11. The delivery pipe 12 penetrates the shield body 1 and is communicated with a spray head 13. A handle 16 is fixed on the surface of the shield body 1. Three grooves are provided on the surface of the handle 16. A switch 17 is fixed on the inner wall of the groove. A compressed air tank 18 is provided inside the ventilation groove 6. A spring 19 and a brushless motor 21 are fixed on the inner wall of the ventilation groove 6. A baffle 22 is fixed on the output shaft of the brushless motor 21. A notch is provided on the surface of the baffle 22. One end of the spring 19 is fixed with a stab cone 20. A spike 14 is fixed on the surface of the shield body 1;

[0020] The shield body 1 can be worn on the position of the user's forearm. The surface of the shield body 1 can resist blunt attacks and sharp attacks such as stabbing, chopping, and splitting, and can well protect the position of the operator's hand. The attack end spike 14 of the shield body 1 can provide physical attacks such as stabbing, chopping, and splitting. The setting of the protective groove 2 can prevent the target from colliding with the spray head 13. By operating the switch 17, the controller 5 can be made to turn on the delivery pump 11, so that the pepper spray stored inside the liquid storage tank 10 can be delivered by the delivery pump 11 into the delivery pipe 12 and sprayed outwards by the spray head 13, so that the pepper spray can attack the face of the enemy, causing the enemy's vision and breathing to be damaged and temporarily losing the offensive ability. By the switch 17, a signal can be sent to the controller 5 to make the power supply structure 3 in a working state, and the brushless motor 21 can be made to drive the baffle 22 to rotate, so that the baffle 22 rotates to a position where the stab cone 20 on the surface can pass through the notch of the baffle 22 by the rebound of the spring 19 and collide with the compressed air tank 18, so that the compressed air inside the compressed air tank 18 can be pushed towards the electrode 8 through the ventilation groove 6, so that the electrode 8 can shoot outwards, and the electrode 8 can instantaneously release a high-voltage current to paralyze the enemy briefly and lose the ability of violent movement, so as to realize the long-range strike on the enemy, so that this arm shield can have both defensive and offensive effects, making the security personnel safer when using it.

[0021] Furthermore, the power supply structure 3 includes a power supply 301, a boost circuit 302, a transformer 303, a rectifier 304, an energy storage unit 305, and a high-voltage output interface 306 fixed on the inner wall of the installation groove 4. The high-voltage output interface 306 is connected to the insulating copper wire 7;

[0022] The low voltage of the power supply 301 is converted into high voltage through the boost circuit 302. The high-voltage alternating current is further boosted by the transformer 303. The boosted alternating current is converted into high-voltage direct current electrical energy after passing through the rectifier 304 and stored inside the energy storage unit 305. The stored high-voltage direct current electrical energy can be transmitted to the inside of the electrode 8 through the high-voltage output interface 306 and the insulated copper wire 7, so that the electrode 8 can release high-voltage current to paralyze the target by electric shock.

[0023] Further, the shield body 1 is made of titanium C5 or Kevlar engineering plastic, and the shock-absorbing plate 9 is made of compressed sponge or polycarbonate, polymethyl methacrylate and thermoplastic polyurethane;

[0024] Titanium C5 alloy has very high strength and can effectively resist various types of physical attacks, including knives and clubs. Kevlar engineering plastic is a high-performance fiber material with high tensile strength and can effectively resist cutting and puncture. When the arm shield is struck, materials such as compressed sponge or polycarbonate have good shock-absorbing performance and can effectively absorb and disperse the impact energy, reducing the impact on the wearer.

[0025] Further, a sheath 15 is threadedly connected to the surface of the spike 14, and the sheath 15 is made of silica gel;

[0026] The sheath 15 can be installed on the surface of the spike 14 so that the spike 14 will not cause accidental injury when the operator is training.

[0027] Further, the surface of the shield body 1 is provided with honeycomb-shaped protrusions;

[0028] The honeycomb structure can increase the overall rigidity of the shield body 1 without significantly increasing the weight because the honeycomb structure can disperse external forces and reduce local stress concentration, thereby improving the overall strength of the shield body 1.

[0029] Further, a knob 23 penetrates through the surface of the shield body 1 in a threaded manner;

[0030] After the knob 23 is screwed out from the surface of the shield body 1, the damaged compressed gas cylinder 18 can be replaced.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
