s1, fixing a bracket body on a test bench;
s2, inverting the gun, and placing a receiver body pick-up support on the gun on an upper-stage step plane to enable a dovetail on one side of the pick-up to be matched with the first dovetail groove;
s3, supporting and placing the lower end surface of the clamping block on the plane of the lower step, and matching locking screws on the clamping block to enable the second dovetail head to be embedded into the second dovetail groove to form positioning of the clamping block, wherein at the moment, a third dovetail groove is formed by combining the first dovetail head with the plane of the upper step;
and S4, tightening the locking screw, and matching the first dovetail groove and the third dovetail groove with dovetails on two sides of the clamping leather card.
Preferably, in step S2, the pickup slot is engaged with one end of the positioning boss on the upper level step plane, and the firearm is pushed in the transverse direction until the dovetail on one side of the pickup slot is engaged with the first dovetail slot.
Due to the adoption of the technical scheme, the invention has the following beneficial effects:
the invention adopts a separated dovetail groove structure with front and rear positioning bosses to be matched with a leather card dovetail structure on a casing body, and uses locking screws to clamp and fix. The fixing device is simple in structure, quick to assemble and disassemble, reliable in front-back, left-right positioning, firm in clamping and free of damaging the surface quality of the gun barrel and the lower casing.

Detailed Description
Referring to fig. 1-4, a firearm holder for high precision shooting tests. The device mainly comprises a bracket body, a clamping block, 3 phi 12 gaskets and M12 locking screws. The support body is the inverted T-shaped structure with a sectional type half dovetail groove, and 2 positioning bosses matched with the casing body leather clamping groove are designed on the support body and used for positioning the casing body front and back. When the high-precision shooting test is carried out, the support body is fixed on the test bench, and then the cartridge receiver body pick-up dovetail on the gun is matched with the support body dovetail groove and the pick-up is matched with the support body positioning boss in place. And then 3 clamping blocks with upper and lower dovetail grooves are respectively corresponding to the dovetail grooves of the bracket body, and are clamped by 3M 12 locking gaskets and screws.
A method for installing a firearm fixing device for a high-precision shooting test comprises the steps of firstly unscrewing 3 phi 12 gaskets 3 and M12 locking screws 4 in the fixing device through a screwdriver to take off a clamping block 2, secondly positioning a firearm 5 through a positioning boss in a bracket body 1, pushing the firearm 5 into a dovetail groove of the bracket body 1 from right to left to be matched with a cartridge receiver leather card dovetail in the firearm 5, then installing the clamping block 2, and finally clamping the firearm 5 through the 3 phi 12 gaskets 3 and the M12 locking screws 4. The firearm fixing device is reliable in clamping, the surface quality of the firearm is not damaged, manpower is greatly reduced, and erroneous judgment of precision caused by artificial factors is avoided.
