Description

Technical Field

[0001] This invention relates to the field of firearm control technology, and more particularly to an adjustable firearm clamp. Background Technology

[0002] With the continuous development of firearms technology, the performance requirements for firearms have become more stringent and clearly defined. The most prominent aspect of this is the assessment and testing of various performance parameters of firearms. During firing performance testing, firearms must be reliably held in place using clamps.

[0003] Traditional standard pistol grips are typically designed for specific firearm models, with fixed shapes and sizes, making them unsuitable for different types of firearms. In terms of operational flexibility, standard pistol grips usually employ a fixed design, with relatively simple adjustment and securing methods, including using bolts and threads to fix the firearm to the grip. However, adjustments often require tools during loading and unloading, making them somewhat cumbersome. Regarding grip stability, the vibration reduction mechanisms of standard pistol grips are generally simple, primarily considering basic grip stability and minimal recoil mitigation. Common methods include adding rubber pads or soft materials to key contact points of the grip, such as the grip surface or the rear of the firearm, to absorb some recoil and vibration. However, the vibration reduction effect is limited, resulting in a poor shooting experience during firearm performance testing. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides an adjustable gun clamp that is highly applicable, flexible, convenient to hold and highly stable.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0006] This application provides an adjustable firearm clamp, including a turntable mechanism, a connecting seat fixedly mounted on the turntable mechanism, a clamping frame rotatably mounted on the connecting seat, and a pitch adjustment component for driving the clamping frame to swing relative to the connecting seat.

[0007] The clamping frame is provided with a tail positioning mechanism for limiting the stock portion of the gun body, a head positioning mechanism for limiting the head portion of the gun body, and a grip positioning assembly for limiting the grip portion of the gun body.

[0008] The turntable mechanism can drive the connecting seat to rotate, and at least one of the gun tail positioning mechanism, gun head positioning mechanism, and grip positioning assembly can adjust its relative position to the connecting seat along the length of the gun body.

[0009] Further specifying, the aforementioned adjustable firearm clamp also includes a stock shock absorber assembly disposed on the clamping frame and located on the side of the buttstock positioning mechanism away from the headstock positioning mechanism and the grip positioning assembly.

[0010] Further specifying, in the above-mentioned adjustable firearm clamp, the stock shock absorption assembly includes a fixed base fixedly connected to the clamping frame, an adjusting column elastically slidably disposed on the fixed base, and an abutment fixedly disposed on the adjusting column and capable of abutting against the stock portion of the firearm body.

[0011] In the case of the abutment column being in contact, the adjusting column does not accumulate elastic potential energy or has elastic potential energy that moves towards the side of the gun body.

[0012] Further specifying, in the aforementioned adjustable firearm clamp, the pitch adjustment assembly includes a cylinder hinged to a turntable mechanism, the telescopic end of which is hinged to the clamping frame.

[0013] Further specifying, in the above-mentioned adjustable firearm clamp, the connecting seat includes a seat body fixedly mounted on a turntable mechanism, and an arc-shaped insert with its center located on the rotation axis of the support frame is fixedly provided on the seat body, and the insert is provided with teeth;

[0014] The support frame is rotatably mounted on the base. The pitch adjustment assembly includes a motor fixedly mounted on the support frame. A drive shaft is poweredly connected to the motor, and a drive gear that meshes with the teeth is fixedly mounted on the drive shaft.

[0015] Further specifying, in the aforementioned adjustable firearm clamp, the gun tail positioning mechanism and / or gun head positioning mechanism includes a pressure plate fixedly connected to the clamping frame and capable of swinging and pressing the gun body, and a locking part for locking the pressure plate in the locked state.

[0016] Further specifying, in the aforementioned adjustable firearm clamp, the butt positioning mechanism and / or head positioning mechanism further include a base fixedly connected to the clamping frame, and the pressure plate is hinged to the base;

[0017] The base has a fixed end and a movable end that can be raised and lowered relative to the fixed end, and the pressure plate is hinged to the movable end of the base.

[0018] Further specifying, the aforementioned adjustable firearm clamp, wherein the gun tail positioning mechanism and / or gun head positioning mechanism further includes a platform for supporting the bottom of the gun body and two clamping plates for respectively abutting and limiting the two sides of the gun body, and limiting linkage assemblies are respectively provided between the platform, the base and the two clamping plates.

[0019] When the platform moves away from the pressure plate, it can drive the two clamping plates to move closer to the gun body through the limiting linkage assembly to achieve lateral clamping and limiting of the gun body.

[0020] Further specifying, in the aforementioned adjustable firearm clamp, the grip positioning assembly includes a positioning fork fixedly connected to the clamping frame, a connecting plate hinged to the positioning fork, a limiting fork fixedly mounted on the connecting plate, and a locking assembly for swinging and locking the connecting plate.

[0021] Further specifying, in the aforementioned adjustable firearm clamp, the grip positioning assembly further includes a fixing plate fixedly connected to the clamping frame;

[0022] The positioning fork of the grip positioning assembly can slide along the length of the gun body on the clamping frame, and a grip shock-absorbing spring is fixed between it and the fixing plate.

[0023] This invention has at least the following beneficial effects:

[0024] 1. When the gun body is placed on the clamping frame, the buttstock, muzzle, and grip of the gun body can be clamped and limited by the buttstock positioning mechanism, muzzle positioning mechanism, and grip positioning component. At the same time, for different models and specifications of gun bodies, the relative positions of the buttstock positioning mechanism, muzzle positioning mechanism, grip positioning component and connecting seat can be adjusted to adapt to the gun body, thereby ensuring the reliability of the gun body clamping. After the gun body is installed, the turntable mechanism can realize the lateral swing of the gun body, and the pitch adjustment component can realize the longitudinal swing of the gun body, thereby realizing the control of the firing angle of the gun body, which greatly improves the operational flexibility and shooting accuracy of the gun body, making the firearm clamp adaptable to different shooting scenarios, and making the shooting experience more personalized, comfortable and efficient.

[0025] 2. Since the gun will generate vibration and recoil when firing, the stock shock absorber can absorb part of the recoil and vibration energy of the gun, thereby reducing the vibration of the gun when firing and improving its shooting accuracy.

[0026] 3. When the cylinder extends or retracts, it can drive the clamping frame to swing relative to the connecting seat to adjust the pitch angle of the gun body. At the same time, if the gun body moves up and down during firing, that is, the pitch angle of the gun body will change under the action of recoil, thus affecting the accuracy of shooting. At this time, the extension and retraction damping provided by the cylinder can reduce the upward movement of the gun body under the action of recoil, thereby making the gun more stable.

[0027] 4. The pitch adjustment assembly adopts a gear and rack transmission mechanism, which can further improve the accuracy of the gun's pitch angle adjustment;

[0028] 5. When the gun head is placed on the platform, the downward pressure of the gun will cause the platform to move away from the pressure plate. This will cause the two clamping plates to move closer to the gun body through the limit linkage assembly, thereby achieving lateral clamping and limiting of the gun body and further improving the clamping reliability of the gun body.

[0029] 6. The grip shock-absorbing spring can buffer the recoil of the grip part when firing the gun. Combined with the stock shock-absorbing component to buffer the stock part of the gun and the cylinder to dampen the pitch of the gun, it can achieve all-round shock absorption when firing the gun, which makes it easier to control the gun during firing and provides a more stable and accurate shooting environment.

[0030] 7. The gun tail positioning mechanism, gun head positioning mechanism, and grip positioning assembly can achieve quick fixing and release of the gun body through simple operation, greatly improving the loading and unloading efficiency of the gun body. Attached Figure Description

Detailed Implementation

[0044] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0045] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0046] The adjustable firearm clamp provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0047] Example 1

[0048] like Figures 1 to 11 As shown, this application provides an adjustable firearm clamp, including a turntable mechanism 100, a connecting seat 110 fixedly installed on the rotating output end of the turntable mechanism 100, a clamping frame rotatably disposed on the connecting seat 110, and a pitch adjustment component for driving the clamping frame to swing relative to the connecting seat 110.

[0049] The clamping frame is fixedly connected to a buttstock positioning mechanism 220 for limiting the stock portion of the gun body 400, a head positioning mechanism 230 for limiting the head portion of the gun body 400, and a grip positioning assembly 240 for limiting the grip portion of the gun body 400.

[0050] Among them, at least one of the tail positioning mechanism 220, the head positioning mechanism 230, and the grip positioning assembly 240 can be adjusted to adjust the relative position between itself and the connecting seat 110 along the length direction of the gun body 400.

[0051] In this embodiment, an adjustable firearm clamp is used. When the firearm 400 is placed on the clamping frame, the buttstock, muzzle, and grip of the firearm 400 can be clamped and limited by the buttstock positioning mechanism 220, muzzle positioning mechanism 230, and grip positioning component 240. Furthermore, for different models and specifications of firearm 400, the relative positions of the buttstock positioning mechanism 220, muzzle positioning mechanism 230, grip positioning component 240, and connecting seat 110 can be adjusted to adapt to different firearm 400 models, ensuring reliable clamping. After the firearm 400 is installed, the turntable mechanism 100 allows for lateral swinging of the firearm 400, and the pitch adjustment component allows for longitudinal swinging, thereby controlling the firing angle of the firearm 400. This greatly improves the operational flexibility and shooting accuracy of the firearm 400, enabling the firearm clamp to adapt to different shooting scenarios and providing a more personalized, comfortable, and efficient shooting experience.

[0052] It is understandable that the butt positioning mechanism 220, the muzzle positioning mechanism 230, and the grip positioning assembly 240 can be set with degrees of freedom based on the initial positioning reference. When the gun body 400 takes the stock as the initial positioning reference, the muzzle positioning mechanism 230 and / or the grip positioning assembly 240 can be set to an adjustable relative position with the connecting seat 110, thereby achieving adaptation to gun bodies 400 of different specifications. Similarly, when the gun body 400 takes the grip as the initial positioning reference, the butt positioning mechanism 220 and / or the muzzle positioning mechanism 230 can be set to an adjustable relative position with the connecting seat 110. If only the butt positioning mechanism 220 or the muzzle positioning mechanism 230 is set to an adjustable relative position with the connecting seat 110, then the positioning structure that cannot be adjusted relative to the connecting seat 110 only needs to ensure applicability to most specifications of gun bodies 400, which will not be elaborated here.

[0053] In a preferred embodiment, such as Figures 1 to 7 As shown, it also includes a stock shock absorber 300 disposed on the clamping frame and located on the side of the butt positioning mechanism 220 away from the head positioning mechanism 230 and the grip positioning assembly 240.

[0054] The stock shock absorber 300 is used to cushion the recoil of the stock portion of the gun body 400.

[0055] In this embodiment, an adjustable gun clamp as described above is used. Since the gun body 400 will generate vibration and recoil when firing, the stock shock absorber 300 can absorb part of the recoil and vibration energy of the gun body 400, thereby reducing the vibration of the gun body 400 when firing and thus improving its shooting accuracy.

[0056] In a preferred embodiment, such as Figures 1 to 7 As shown, the clamping frame includes a support frame 200 rotatably mounted on the connecting seat 110 and at least one guide rod 210 mounted on the support frame 200.

[0057] Among them, the butt positioning mechanism 220, the head positioning mechanism 230, the grip positioning assembly 240, the stock shock absorption assembly 300 and the guide rod 210 are fixedly connected.

[0058] In a preferred embodiment, such as Figures 1 to 7 As shown, the stock shock absorber assembly 300 includes a fixed base 310 fixedly connected to the guide rod 210, an adjusting column 320 slidably disposed on the fixed base 310, and a stock shock absorber spring 330 disposed between the adjusting column 320 and the fixed base 310.

[0059] Among them, the adjusting column 320 is parallel to the guide rod 210 and at least one is provided on the fixed base 310. The adjusting column 320 is provided with a stop 340 at the end near the gun tail positioning mechanism 220, which can abut against the gun stock of the gun body 400. The gun stock shock absorption spring 330 can drive the stop 340 to move towards the side closer to the gun body 400 under the action of its own elastic potential energy.

[0060] In a preferred embodiment, such as Figures 1 to 7 As shown, it also includes an automatic firing device 600 that is fixedly connected to the clamping frame and is used for automatic firing control of the gun body 400.

[0061] Understandably, once the gun body 400 is positioned on the clamping frame, the automatic firing device 600 can automatically disengage the safety of the gun body 400 and automatically trigger the trigger. Combined with the clamp's control over the firing angle of the gun body 400, automatic firing control of the gun body 400 can be performed without manual intervention, greatly improving the efficiency and safety of firearm firing operations.

[0062] Example 2

[0063] like Figures 1 to 4 As shown, this application provides an adjustable firearm clamp, which includes the structural features of the aforementioned embodiment 1.

[0064] The pitch adjustment assembly includes a cylinder 500 hinged to the rotation output end of the turntable mechanism 100, and the telescopic end of the cylinder 500 is hinged to the clamping frame.

[0065] In this embodiment, an adjustable firearm clamp as described above is used. When the cylinder 500 extends or retracts, it can drive the guide rod 210 and the support frame 200 to swing relative to the connecting seat 110 to adjust the pitch angle of the gun body 400. At the same time, during the firing process, if the gun body 400 has a vertical movement, that is, the pitch angle of the gun body 400 will change under the action of recoil, thereby affecting the accuracy of shooting. At this time, the extension and retraction damping provided by the cylinder 500 can reduce the vertical movement of the gun body 400 under the action of recoil, thereby making the gun more stable.

[0066] It is understandable that the pitch adjustment component is not limited to the one mentioned above, as long as it can achieve 400 degrees of pitch angle control of the gun body, it will not be elaborated here.

[0067] In a preferred embodiment, such as Figures 1 to 4 As shown, the guide rod 210 is slidably mounted on the support frame 200, and two threaded parts are threadedly connected to the guide rod 210. The two threaded parts can respectively abut against the opposite end faces of the support frame 200 in the axial direction of the guide rod 210, thereby fixing the guide rod 210 on the support frame 200.

[0068] The gun tail positioning mechanism 220 is fixedly mounted on the support frame 200, and the gun head positioning mechanism 230 and the grip positioning assembly 240 are mounted on the guide rod 210. When the threaded part on the guide rod 210 is loosened from the support frame 200, the guide rod 210 can slide relative to the support frame 200, thereby driving the gun head positioning mechanism 230 and the grip positioning assembly 240 to move to adjust their relative positions with the gun tail positioning mechanism 220, thereby achieving adaptation to gun bodies 400 of different specifications.

[0069] In a preferred embodiment, such as Figures 1 to 4 As shown, the gun head positioning mechanism 230 is fixedly mounted on the guide rod 210, and the grip positioning assembly 240 is slidably mounted on the guide rod 210.

[0070] The guide rod 210 is threaded with two threaded parts, which can respectively abut against the opposite end faces of the grip positioning assembly 240 in the axial direction of the guide rod 210, thereby fixing the grip positioning assembly 240 on the guide rod 210.

[0071] Understandably, after the stock of the gun body 400 is limited by the buttstock positioning mechanism 220, the distance between the headstock positioning mechanism 230 and the guide rod 210 can be adjusted by adjusting the relative position of the guide rod 210 and the support frame 200, thereby adapting to the distance between the stock and the head of the gun body 400. By adjusting the relative position of the grip positioning component 240 on the guide rod 210, the position of the grip of the gun body 400 can be adapted, thereby achieving comprehensive limitation of the stock, head, and grip of the gun body 400.

[0072] It is understandable that the configuration of the butt positioning mechanism 220, the head positioning mechanism 230, and the grip positioning component 240 is not limited to the above one. As long as the relative positions can be adjusted according to the specifications of the gun body 400, it will not be elaborated here.

[0073] In a preferred embodiment, such as Figures 1 to 4 As shown, the gun tail positioning mechanism 220 includes a gun tail pressure plate 221 rotatably mounted on the support frame 200 and a first locking part 223 for locking the gun tail pressure plate 221 in a latching state.

[0074] Understandably, when the stock of the gun body 400 is placed on the clamping frame, the butt plate 221 can be rotated and engaged to press against the end face of the stock of the gun body 400 away from the clamping frame. When the first locking part 223 locks the engagement state of the butt plate 221, the stock of the gun body 400 is locked.

[0075] In a preferred embodiment, such as Figures 1 to 4 As shown, a first hinge 222 is fixed between the gun tail pressure plate 221 and the support frame 200, that is, the gun tail pressure plate 221 is rotatably connected to the support frame 200 through the first hinge 222.

[0076] In a preferred embodiment, clamping members are retractably provided on both sides of the gun body 400 on the gun tail plate 221. When the gun tail plate 221 is engaged, the clamping members can be adjusted to further clamp and limit the sides of the gun body 400, thereby improving the clamping reliability of the gun body 400.

[0077] In a preferred embodiment, such as Figures 1 to 4 As shown, the gun head positioning mechanism 230 includes a second base 234 fixedly mounted on the guide rod 210, a gun head pressure plate 231 rotatably mounted on the second base 234, and a second locking part 233 for locking the gun head pressure plate 231 in a latching state.

[0078] Understandably, when the gun head of the gun body 400 is placed on the clamping frame, the gun head pressure plate 231 can be rotated and engaged to press against the end face of the gun head of the gun body 400 away from the clamping frame. When the second locking part 233 locks the engagement state of the gun head pressure plate 231, the gun head of the gun body 400 is locked.

[0079] In a preferred embodiment, such as Figures 1 to 4 As shown, a second hinge 232 is fixedly provided between the gun head pressure plate 231 and the second base 234, that is, the gun head pressure plate 231 is rotatably connected to the second base 234 through the second hinge 232.

[0080] In a preferred embodiment, clamping members are retractably provided on the gun head pressure plate 231 on both sides of the gun body 400. When the gun head pressure plate 231 is engaged, the clamping members can be adjusted to further clamp and limit the sides of the gun body 400, thereby improving the clamping reliability of the gun body 400.

[0081] In a preferred embodiment, such as Figures 1 to 4 As shown, the grip positioning assembly 240 includes a positioning fork 243 fixedly connected to the guide rod 210, a connecting plate 241 rotatably mounted on the positioning fork 243, a limiting fork 248 fixedly mounted on the connecting plate 241, and a locking assembly for swing locking the connecting plate 241.

[0082] The locking assembly includes a limit screw 246 hinged to the positioning fork 243, a limit nut 247 threadedly connected to the limit screw 246, and a travel groove on the positioning fork 248 for the limit screw 246 to pass through.

[0083] In the locked state of the grip positioning component 240, the grip of the gun body 400 is located between the positioning fork 243 and the limiting fork 248, the limiting screw 246 is located in the stroke groove of the limiting fork 248, and the limiting nut 247 abuts against the end face of the limiting fork 248 away from the positioning fork 243.

[0084] Understandably, when the grip positioning component 240 is not locked, the limiting fork 248 is in the open state. At this time, the grip of the gun body 400 can be placed between the positioning fork 243 and the limiting fork 248. When the grip positioning component 240 is locked, the limiting fork 248 is rotated to abut against the grip of the gun body 400. At this time, the limiting screw 246 is rotated into the stroke groove of the limiting fork 248, and the limiting nut 247 is rotated to abut against the limiting fork 248. Under the abutting action of the limiting nut 247, the relative position of the limiting fork 248 and the positioning fork 243 is fixed, thereby achieving the limiting of the grip part of the gun body 400.

[0085] In this embodiment, an adjustable firearm clamp as described above is used. The butt positioning mechanism 220, the head positioning mechanism 230, and the grip positioning component 240 can quickly fix and release the firearm body 400 through simple operation, greatly improving the loading and unloading efficiency of the firearm body 400.

[0086] In a preferred embodiment, such as Figures 1 to 4 As shown, a third hinge 242 is fixedly provided between the connecting plate 241 and the positioning fork 243, that is, the connecting plate 241 is rotatably connected to the positioning fork 243 through the third hinge 242.

[0087] In a preferred embodiment, such as Figures 1 to 4 As shown, the grip positioning assembly 240 also includes a fixing plate 244 fixedly connected to the guide rod 210, and a grip damping spring 245 is fixedly provided between the positioning fork 243 and the guide rod 210 and the fixing plate 244.

[0088] In this embodiment, an adjustable firearm clamp as described above is used. The grip damping spring 245 can buffer the recoil of the grip part when the gun body 400 is fired. Combined with the buffering of the buttstock damping component 300 on the buttstock part of the gun body 400 and the pitch damping of the cylinder 500 on the gun body 400, it can achieve all-round shock absorption when the gun body 400 is fired, which facilitates better control of the firearm during firing and provides a more stable and accurate firing environment.

[0089] In a preferred embodiment, such as Figures 1 to 4 As shown, the automatic firing device 600 is fixedly mounted on the connecting plate 241.

[0090] In a preferred embodiment, such as Figures 1 to 4 As shown, the first locking part 223 and / or the second locking part 233 are specifically configured as a snap-fit ​​structure.

[0091] Example 3

[0092] like Figures 5 to 11 As shown, this application provides an adjustable firearm clamp, which includes the structural features of the aforementioned embodiment 1.

[0093] The connecting seat 110 includes a seat body 111 fixedly mounted on the rotation output end of the turntable mechanism 100, an insert 112 fixedly mounted on the seat body 111, and a toothed part 113 mounted on the insert 112.

[0094] The support frame 200 is rotatably mounted on the base 111. The pitch adjustment assembly includes a motor 720 fixedly mounted on the support frame 200. A drive shaft 730 is poweredly connected to the motor 720. A drive gear 710 that meshes with the toothed part 113 is fixedly mounted on the drive shaft 730.

[0095] The insert 112 is arc-shaped with its center located on the rotation axis of the support frame 200. When the motor 720 drives the drive gear 710 to rotate through the transmission shaft 730, the drive gear 710 drives the support frame 200 to rotate relative to the connecting seat 110 under the meshing action of the teeth 113, thereby adjusting the pitch angle of the clamping frame.

[0096] In this embodiment, an adjustable firearm clamp as described above is used, and the pitch adjustment component adopts a gear and rack transmission mechanism, which can further improve the adjustment accuracy of the firearm's 400° pitch angle.

[0097] It is understandable that the structure of the pitch adjustment component is not limited to the one mentioned above, as long as it can achieve a 400° pitch angle adjustment of the gun body, it will not be elaborated here.

[0098] In a preferred embodiment, such as Figures 5 to 11 As shown, there are two inserts 112 symmetrically arranged on the base 111 about the gun body 400, and two drive gears 710 are fixedly arranged on the transmission shaft 730. The two drive gears 710 are respectively meshed with the teeth 113 on the two inserts 112.

[0099] It is understandable that the above settings can ensure the force balance of the support frame 200 when the pitch adjustment component is driven, thereby improving the pitch adjustment stability of the gun body 400.

[0100] In a preferred embodiment, such as Figures 5 to 11 As shown, the support frame 200 is provided with a guide groove 201 that slides with the insert 112.

[0101] It is understandable that the sliding fit between the guide groove 201 and the insert 112 can guide the rotation of the support frame 200 relative to the connecting seat 110, thereby further improving the pitch adjustment stability of the gun body 400.

[0102] In a preferred embodiment, such as Figures 5 to 7 As shown, the grip positioning assembly 240 includes a positioning fork fixedly mounted on the guide rod 210, a connecting plate hinged to the positioning fork, a limiting fork fixedly mounted on the connecting plate, and a locking assembly for swing locking the connecting plate.

[0103] The locking assembly includes a travel groove provided on the limit fork for the guide rod 210 to pass through, and a limit nut is threadedly connected to the guide rod 210.

[0104] In the locked state of the grip positioning component 240, the grip of the gun body 400 is located between the positioning fork and the limiting fork, the guide rod 210 is located in the stroke groove of the limiting fork and the limiting nut abuts against the end face of the limiting fork away from the positioning fork.

[0105] Understandably, when the grip positioning component 240 is not locked, the limiting fork is in the open state. At this time, the grip of the gun body 400 can be placed between the positioning fork and the limiting fork. When the grip positioning component 240 is locked, the limiting fork is rotated to abut against the grip of the gun body 400. At this time, the limiting nut is rotated to abut against the limiting fork. Under the abutment of the limiting nut, the relative position of the limiting fork and the positioning fork is fixed, thereby achieving the limitation of the grip part of the gun body 400.

[0106] In a preferred embodiment, such as Figures 5 to 7 As shown, the automatic firing device 600 is fixedly mounted on the connecting plate.

[0107] In a preferred embodiment, such as Figures 5 to 7 As shown, the gun tail positioning mechanism 220 and the gun head positioning mechanism 230 are configured to be adjustable relative to the connecting seat 110.

[0108] Understandably, the grip positioning component 240 is fixedly mounted on the guide rod 210. After the grip part of the gun body 400 is limited by the grip positioning component 240, the stock part and the muzzle part of the gun body 400 can be adapted by adjusting the relative positions of the butt positioning mechanism 220, the muzzle positioning mechanism 230 and the grip positioning component 240 respectively.

[0109] In a preferred embodiment, such as Figures 5 to 7 , Figure 10 As shown, the gun tail positioning mechanism 220 includes a first base 224 fixedly connected to the guide rod 210, a gun tail pressure plate 221 rotatably disposed on the first base 224, and a first locking part 223 for locking the gun tail pressure plate 221 in the latching state.

[0110] Understandably, when the stock of the gun body 400 is placed on the first base 224, the butt plate 221 can be rotated and engaged to press against the end face of the gun body 400 away from the first base 224. When the first locking part 223 locks the engagement state of the butt plate 221, the stock of the gun body 400 is locked.

[0111] In a preferred embodiment, such as Figures 5 to 7 , Figure 10 As shown, the gun tail positioning mechanism 220 also includes a first platform 225 for supporting the bottom of the gun stock of the gun body 400 and two first clamping plates 229 for respectively abutting and limiting the two sides of the gun stock of the gun body 400. A gun stock limiting linkage assembly is provided between the first platform 225, the first base 224 and the two first clamping plates 229.

[0112] The stock limiting linkage assembly includes a first swing rod 227 and a second swing rod 228, one end of which is hinged to the side of the first base 224 away from the first clamping plate 229, and the other end of which is hinged to the first clamping plate 229 at the corresponding position. The first swing rod 227 and the second swing rod 228 on the corresponding side are parallel to each other.

[0113] The second swing arm 228 is hinged to the middle of a first connecting rod 226, and the end of the first connecting rod 226 away from the second swing arm 228 is hinged to the corresponding end of the first platform 225.

[0114] In this embodiment, an adjustable firearm clamp as described above is used. When the stock of the gun body 400 is placed on the first platform 225, the downward pressure of the gun body 400 will cause the first platform 225 to move away from the butt plate 221. This will cause the second swing arm 228 to swing through the first connecting rod 226, and then cause the two first clamping plates 229 to move closer to the gun body 400 to achieve lateral clamping and limiting of the gun body 400.

[0115] In a preferred embodiment, such as Figures 5 to 7 , Figure 10 As shown, the first base 224 has a fixed end and a movable end that can be raised and lowered relative to the fixed end, and the gun tail pressure plate 221 is rotatably mounted on the movable end of the first base 224.

[0116] It is understandable that the distance between the gun tail plate 221 and the first platform 225 can be adjusted by raising and lowering the telescopic end of the first base 224, thereby matching the height of the gun stock of different specifications of the gun body 400 and ensuring the clamping and limiting effect of the gun stock part of the gun body 400.

[0117] In a preferred embodiment, the two first clamping plates 229 are provided with self-locking buckle components on their opposite side end faces, and the engaging ends of the two self-locking buckle components can be adjusted in the longitudinal direction and engage with each other.

[0118] Understandably, once the gun body 400 is positioned under the clamping action of the two first clamping plates 229, the engaging ends of the two self-locking latching components can be adjusted according to the height of the clamping position of the gun body 400. The opposing movement of the two first clamping plates 229 can drive the engaging ends of the two self-locking latching components to contact each other and complete the self-locking. When removing, it is only necessary to release the lock, which will not be elaborated here.

[0119] In a preferred embodiment, such as Figures 5 to 7 , Figure 11 As shown, the gun head positioning mechanism 230 includes a second base 234 fixedly connected to the guide rod 210, a gun head pressure plate 231 rotatably disposed on the second base 234, and a second locking part 233 for locking the gun head pressure plate 231 in a latching state.

[0120] Understandably, when the gun head of the gun body 400 is placed on the second base 234, the gun head pressure plate 231 can be rotated and engaged to press against the end face of the gun head of the gun body 400 away from the second base 234. When the second locking part 233 locks the engagement state of the gun head pressure plate 231, the gun head of the gun body 400 is locked.

[0121] In a preferred embodiment, such as Figures 5 to 7 , Figure 11 As shown, the gun head positioning mechanism 230 also includes a second platform 235 for supporting the bottom of the gun head of the gun body 400 and two second clamping plates 239 for respectively abutting and limiting the two sides of the gun head of the gun body 400. Gun head limiting linkage assemblies are respectively provided between the second platform 235, the second base 234 and the two second clamping plates 239.

[0122] The gun head limiting linkage assembly includes a third swing rod 237 and a fourth swing rod 238, one end of which is hinged to the side of the second base 234 away from the second clamping plate 239, and the other end is hinged to the second clamping plate 239 at the corresponding position. The third swing rod 237 and the fourth swing rod 238 on the corresponding side are parallel to each other.

[0123] The fourth swing arm 238 is hinged to the middle of a second connecting rod 236, and the end of the second connecting rod 236 away from the fourth swing arm 238 is hinged to the corresponding end of the second platform 235.

[0124] In this embodiment, an adjustable gun clamp is used. When the gun head of the gun body 400 is placed on the second platform 235, the downward pressure of the gun body 400 will cause the second platform 235 to move away from the gun head pressure plate 231. This will cause the fourth swing rod 238 to swing through the second connecting rod 236, and then cause the two second clamping plates 239 to move closer to the gun body 400 to achieve lateral clamping and limiting of the gun body 400.

[0125] In a preferred embodiment, such as Figures 5 to 7 , Figure 11 As shown, the second base 234 has a fixed end and a movable end that can be raised and lowered relative to the fixed end, and the gun head pressure plate 231 is rotatably mounted on the movable end of the second base 234.

[0126] It is understandable that the distance between the gun head pressure plate 231 and the second platform 235 can be adjusted by raising and lowering the telescopic end of the second base 234, thereby matching the height of the gun head of different specifications of the gun body 400 and ensuring the clamping and limiting effect of the gun head part of the gun body 400.

[0127] In a preferred embodiment, such as Figures 5 to 7 , Figure 11As shown, the second platform 235 has a guide post that is slidably connected to the second base 234. When the gun body 400 presses down and moves the second platform 235 away from the gun head pressure plate 231, the guide post of the second platform 235 can improve the movement stability of the second platform 235, thereby ensuring the clamping consistency of the two second clamping plates 239.

[0128] It is understandable that the structural forms of the butt positioning mechanism 220 and the head positioning mechanism 230 are not limited to the one mentioned above. As long as they can achieve quick clamping and limiting of the stock and head of the gun body 400, they are acceptable and will not be elaborated here.

[0129] In a preferred embodiment, the two second clamping plates 239 are provided with self-locking buckle components on their opposite side end faces, and the engaging ends of the two self-locking buckle components can be adjusted in the longitudinal direction and engage with each other.

[0130] Understandably, once the gun body 400 is positioned under the clamping action of the two second clamping plates 239, the engaging ends of the two self-locking latching components can be adjusted according to the height of the clamping position of the gun body 400. The opposing movement of the two second clamping plates 239 can drive the engaging ends of the two self-locking latching components to contact each other and complete the self-locking. When removing, it is only necessary to release the lock, which will not be elaborated here.

[0131] In a preferred embodiment, such as Figures 5 to 11 As shown, the first locking part 223 and / or the second locking part 233 are specifically configured as a snap-fit ​​structure.
