Firearm fixing clamp

The firearm fixing clamp comprises a base and a clamping mechanism, the base is of a T-shaped structure, a connecting part is formed at the upper end of the base, a connecting guide rail is arranged at the lower end of the base, and the connecting guide rail is used for being connected with an external supporting device; the clamping mechanisms are oppositely fixed to the connecting part at the upper end of the base, and a U-shaped clamping area is formed on each clamping mechanism and used for being matched with the middle of a firearm in a clamping mode. According to the scheme, the pair of clamping mechanisms is ingeniously arranged to assist in clamping the middle of the firearm, the first gasket and the second gasket are further arranged on the pair of clamping mechanisms in an assisting mode to improve the fitting degree of the clamping mechanisms and the firearm, the firearm can be more stable and reliable when the middle of the firearm is clamped in an assisting mode, and meanwhile the clamping effici
