Abstract
Description
Technical Field
[0001] This utility model relates to the field of firearms technology, and in particular to a clamping device for testing the accuracy of a pistol. Background Technology
[0002] Except for revolvers, almost all handguns are magazine-fed. When a handgun leaves the factory, its accuracy needs to be adjusted to a certain range. When the user aims and fires through the sight baseline, the bullet impact point can be controlled within a certain range. The user can fine-tune the sight baseline according to their own shooting habits. When firing a firearm, aiming at the same point, that is, when the sight baseline is fixed, the impact point of multiple bullets should also be controlled within a certain range.
[0003] The accuracy of a firearm is adjusted and tested by the shooter holding and aiming at it. The aiming points of multiple shots are different, and the recoil generated during shooting will cause the firearm to jump, which will also affect the actual value.
[0004] Firearm shooting accuracy mainly includes precision and accuracy. To ensure that pistol shooting accuracy meets the requirements, live-fire testing is necessary. The pistol is held on a fixed stand, and shooting precision and accuracy are tested at a specified distance. For pistols whose accuracy does not meet the requirements, the relationship between the aiming baseline formed by the rear sight and front sight and the rifling of the barrel needs to be adjusted. During the adjustment process, the accuracy of the pistol can be tested simultaneously. The test requires a special device for holding the firearm. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a clamping device for handgun accuracy testing that can accurately clamp the position, requires less labor intensity, and is simple to operate.
[0006] The purpose of this utility model is achieved as follows: A clamping device for handgun accuracy testing includes a base plate. One end of the base plate is fixed with a guide seat and a magazine guide by screws. The magazine guide is located in front of the guide seat and is used to insert into the magazine compartment of the handgun grip from below. The other end of the base plate is a handgun receiving space. The guide seat is U-shaped and has a tail plate and two side plates. The two walls of the guide seat are provided with longitudinal guide rails. The tail plate of the guide seat is threaded with a screw along the longitudinal direction. It also includes a rear pressure block, with guide protrusions on both sides of the rear pressure block. The guide protrusions slide in the guide rail of the guide seat. The front end of the screw corresponds to the tail end of the rear pressure block. A handwheel is provided at the rear end of the screw. The handwheel is used to drive the screw to rotate and move back and forth. When the screw moves forward, it can apply pressure to the rear pressure block, so that the rear pressure block presses against the upper rear end of the pistol grip.
[0007] Preferably, the front end of the rear pressure block is provided with a U-shaped groove, which corresponds to the rear end of the pistol grip, and a buffer is installed in the U-shaped groove.
[0008] Preferably, the lower end of the base is connected to a base that can be adjusted up, down, left, and right.
[0009] Preferably, it also includes a base, the base plate is fixed on the base, the base is slidably fitted on the base, and the end of the base plate facing away from the guide seat is provided with a hinge. A spring is connected between the hinge and the base, and the spring is used to buffer the shot when the pistol is fired.
[0010] Preferably, the bottom of the magazine is provided with a stepped positioning block, which is used to cooperate with the bottom step of the pistol grip to limit the front limit position and the lower limit position of the pistol grip.
[0011] Due to the adoption of the above technical solution, this utility model has the following beneficial effects: The pistol is held in place and the aiming baseline is fixed, so the relationship between the bullet impact point and the aiming point after firing can be clearly reflected on the target paper.
[0012] In addition to revolvers, this invention is applicable to the clamping of all magazine-fed pistols for accuracy adjustment and testing. Attached Figure Description

Detailed Implementation
[0015] See Figure 1 , Figure 2A clamping device for pistol accuracy testing includes a base plate 4. One end of the base plate 4 is fixed with a guide seat 12 and a magazine guide 6 by screws. The magazine guide 6 is located in front of the guide seat 12 and is used to insert into the magazine well of the pistol grip from below. The other end of the base plate 4 is a pistol receiving space. The guide seat 12 is U-shaped and has a tail plate and two side plates. Guide rails are provided longitudinally on both walls of the guide seat 12. A screw thread is threaded longitudinally onto the tail plate of the guide seat 12. The device includes a rod 13; it also includes a rear pressure block 11, with guide protrusions on both sides of the rear pressure block 11, which are slidably fitted in the guide rail of the guide seat 12. The front end of the screw 13 corresponds to the rear end of the rear pressure block 11, and a handwheel 15 is provided at the rear end of the screw 13. The handwheel 15 is used to drive the screw 13 to rotate and move back and forth. When the screw 13 moves forward, it can apply pressure to the rear pressure block 11, so that the rear pressure block 11 presses against the upper rear end of the pistol grip (the pistol grip is designed to be tilted, i.e., applying pressure forward and downward). It also includes a base 3, on which the base plate 4 is fixed. The base 3 is slidably fitted on the base (not shown). A hinge 1 is provided at the end of the base plate 4 facing away from the guide seat 12. A spring is connected between the hinge 1 and the base, and the spring is used to buffer the impact when the pistol is fired.
[0016] The rear pressure block 11 has a U-shaped groove at its front end, which corresponds to the rear end of the pistol grip. A buffer is installed inside the U-shaped groove. The buffer is made of cowhide 10 or rubber to prevent the pistol from being pinched. The bottom of the magazine guide 6 has a stepped positioning block, which is used to cooperate with the bottom step of the pistol grip to limit the front limit position and the lower limit position of the pistol grip.
[0017] Specifically: As attached Figure 1 , Figure 2 The magazine guide 6 is fixed to the base plate 4 by a screw plate. During use, the pistol is loaded into the clamping device from the magazine guide 6. The guide seat 12 is also screwed onto the base plate 4. A guide rail is designed on the guide seat 12, connecting to the rear clamping block 11. The rear clamping block 11 is fitted with leather 10 or rubber by screws to prevent damage to the pistol. The screw 13 is threaded onto the guide seat, its front end connected to the rear clamping block 11, and its rear end connected to the handwheel 15. The handwheel is fixed to the screw by a nut 14. Rotating the handwheel moves the screw forward, pushing the rear clamping block 11 forward and clamping the pistol. The base 3 connects to the adjustable base. The entire device is connected to a spring via a hinge 1. The spring is fixed to the front-end fixing device, providing a buffer during firing.
[0018] By pulling the bolt (or slide), a cartridge is loaded through the ejection port. Releasing the bolt (or slide) completes the locking. After aiming by adjusting the receiver connected to the base 3, the cartridge is fired. The firearm and the device slide on the receiver via the base 3, with the spring connected to the front end acting as a buffer.
[0019] The accuracy adjustment and accuracy test of different magazine-fed pistols can be adapted by changing the magazine profile 6.
[0020] Once the pistol is cocked, it remains stationary. Its accuracy adjustment and accuracy testing require manual loading of a cartridge through the ejection port, with only one cartridge loaded at a time.
[0021] The entire device is connected to the base via base 3, which can slide parallel to the base. The recoil generated after the pistol is fired can be buffered by the spring connected by hinge 1, preventing the pistol parts from malfunctioning.
[0022] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
