Anti-robbery holster provided with protective mechanism and facilitating insertion and drawing of gun

The invention discloses an anti-robbery holster provided with a protective mechanism and facilitating insertion and drawing of a gun. The anti-robbery holster comprises a waist protecting plate, a holster body arranged on one side of the waist protecting plate, a locating supporting plate on the side, close to the waist protecting plate, of the upper portion of the holster body, an L-shaped connecting plate arranged on the locating supporting plate and a locating supporting clamp arranged on one side of the locating supporting plate. A pressing part is arranged on the side close to the waist protecting plate and is not likely to be touched by external force, so that the gun is not likely to be lost or robbed, and protection is firm. The L-shaped connecting plate and the holster body are fixed and locked through a locating column by clamping gaskets and an E-shaped meson. The L-shaped connecting plate is matched with the locating supporting clamp in space according to the level principle. The anti-robbery holster is triggered integrally and is simple in mechanical structure, low in failure rate and reliable in practical application. The trigger mode that the pressing part is shifted by pressing a thumb and the gun drawing action are conducted simultaneously. The gun drawing speed is increased. The gun can be taken out rapidly.
