Description

Adjustable firearm clamp

[0001] This application claims the benefit of Chinese patent application No. 2024100842431, filed on January 19, 2024. This application incorporates the entirety of the aforementioned Chinese patent application. Technical Field

[0002] The present invention relates to the technical field of firearm control, and in particular to an adjustable firearm clamp. Background Art

[0003] With the continuous development of firearms technology, the performance requirements for firearms have become more stringent and clearer. The most prominent of these requirements is the assessment and testing of various firearm performance parameters. During shooting performance testing, firearms must be securely clamped using a fixture.

[0004] Traditional, standard gun grips are typically designed for specific gun models, with fixed shapes and sizes, making them unsuitable for different types of guns. In terms of operational flexibility, standard gun grips typically employ a fixed design, with relatively simple adjustment and fixing methods, including bolts and threads to secure the gun to the grip. These typically require tools for adjustment during loading and unloading, making them cumbersome to use. In terms of grip stability, the vibration reduction mechanisms of standard gun grips are typically simple, primarily focusing on basic grip stability and a small amount of recoil relief. These methods typically include adding rubber pads or soft materials to key contact points of the grip, such as the grip surface or the rear of the gun, to absorb some recoil and vibration. However, these methods have limited vibration reduction effects, resulting in poor shooting experience during gun performance testing.

[0005] Summary of the Invention

[0014] It is further defined that in the above-mentioned adjustable firearm clamp, the pitch adjustment assembly includes a cylinder hingedly arranged on the turntable mechanism, and the telescopic end of the cylinder is hingedly connected to the clamping frame.

[0015] It is further defined that in the above-mentioned adjustable firearm clamp, the engaging seat includes a seat body fixedly mounted on the turntable mechanism, the seat body is fixedly provided with an arc-shaped insert with its center located on the rotation axis of the support frame, and the insert is provided with a tooth portion;

A transmission shaft is provided on the motor for power connection. A driving gear meshing with the toothed portion is fixed on the transmission shaft.

[0017] It is further defined that the above-mentioned adjustable firearm clamp, wherein the gun tail positioning mechanism and / or the gun head positioning mechanism includes a pressure plate fixedly connected to the clamping frame and capable of swinging to clamp the gun body, and a locking portion for locking the clamping state of the pressure plate.

[0018] It is further defined that in the above-mentioned adjustable firearm clamp, the gun tail positioning mechanism and / or the gun head positioning mechanism further comprises a base fixedly connected to the clamping frame, and the pressure plate is hingedly disposed on the base;

[0019] 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 hingedly arranged on the movable end of the base.

[0020] It is further defined that in the above-mentioned adjustable firearm clamp, the gun tail positioning mechanism and / or the gun head positioning mechanism further includes a platform for supporting the bottom of the gun body and two clamping plates for respectively restraining two side surfaces of the gun body, and a limiting link assembly is respectively provided between the platform, the base and the two clamping plates;

[0021] When the platform moves away from the pressure plate, the two clamping plates can be driven to move toward the gun body through the limiting link assembly to achieve lateral clamping and limiting of the gun body.

[0022] It is further defined that the above-mentioned adjustable firearm clamp, wherein the grip positioning assembly includes a positioning fork frame fixedly connected to the clamping frame, a connecting plate hingedly arranged on the positioning fork frame, a limiting fork frame fixedly arranged on the connecting plate, and a locking assembly for swinging and locking the connecting plate.

[0025] The present invention has at least the following beneficial effects:

[0026] 1. When the gun body is placed on the clamping frame, the buttstock positioning mechanism, the head positioning mechanism, and the grip positioning assembly can be used to clamp and limit the buttstock, head, and grip of the gun body respectively. At the same time, for gun bodies of different models and specifications, the relative positions of the buttstock positioning mechanism, the head positioning mechanism, the grip positioning assembly, and the connecting seat can be adjusted to adapt to the gun body, thereby ensuring the clamping reliability of the gun body.

[0027] 2. Since the gun body will generate vibration and recoil when firing, the buttstock shock-absorbing assembly can absorb part of the recoil and vibration energy of the gun body, thereby reducing the vibration of the gun body during shooting and improving its shooting accuracy;

[0028] 3. When the cylinder is extended or retracted, it can drive the clamping frame to swing relative to the connecting seat to adjust the gun body's pitch angle. At the same time, during the shooting process, if the gun body moves up and down, that is, the gun body's pitch angle will change under the action of recoil, thus affecting the shooting accuracy. At this time, the expansion and contraction damping provided by the cylinder can reduce the gun body's lifting movement under the action of recoil, thereby making the gun more stable.

[0029] 4. The pitch adjustment assembly adopts a rack and pinion transmission mechanism, which can further improve the adjustment accuracy of the gun body's pitch angle;

[0030] 5. When the gun head is placed on the platform, the downward pressure of the gun body will drive the platform to move away from the pressure plate, thereby driving the two clamping plates to move closer to the gun body through the limit link assembly to achieve lateral clamping and limiting of the gun body, further improving the clamping reliability of the gun body;

[0031] 6. The grip damping spring can buffer the recoil of the grip when firing. Combined with the buttstock damping assembly's buffering of the gun butt and the cylinder's pitch damping of the gun, it can achieve comprehensive shock absorption during firing, facilitating better control of the gun during shooting and providing a smoother and more accurate shooting environment.

[0032] 7. The gun tail positioning mechanism, gun head positioning mechanism, and grip positioning assembly can realize the rapid fixation and release of the gun body through simple operation, greatly improving the loading and unloading efficiency of the gun body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0046] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0047] The adjustable firearm clamp provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0048] Example 1

[0049] As shown in Figures 1 to 11, an embodiment of the present application provides an adjustable firearm clamp, including a turntable mechanism 100, a connecting seat 110 fixedly mounted on the rotation output end of the turntable mechanism 100, a clamping frame rotatably arranged on the connecting seat 110, and a pitch adjustment component for driving the clamping frame to swing relative to the connecting seat 110.

[0050] The clamping frame is fixedly connected with a gun tail positioning mechanism 220 for limiting the butt portion of the gun body 400, a gun head positioning mechanism 230 for limiting the gun head portion of the gun body 400, and a grip positioning assembly 240 for limiting the grip portion of the gun body 400.

[0051] Among them, at least one of the gun tail positioning mechanism 220 , the gun head positioning mechanism 230 , and the grip positioning assembly 240 can adjust the relative position with the connecting seat 110 along the length direction of the gun body 400 .

[0052] In the embodiment of the present application, the above-mentioned adjustable firearm clamp is adopted. When the gun body 400 is placed on the clamping frame, the buttstock, gun head and grip of the gun body 400 can be clamped and limited respectively through the butt positioning mechanism 220, the gun head positioning mechanism 230 and the grip positioning assembly 240. At the same time, for gun bodies 400 of different models and specifications, the gun body 400 can be adapted by adjusting the relative positions of the butt positioning mechanism 220, the gun head positioning mechanism 230, the grip positioning assembly 240 and the connecting seat 110, thereby ensuring the clamping reliability of the gun body 400. After the gun body 400 is installed, the lateral swing of the gun body 400 can be achieved through the turntable mechanism 100, and the longitudinal swing of the gun body 400 can be achieved through the pitch adjustment assembly, thereby realizing the shooting angle control of the gun body 400, which greatly improves the operational flexibility and shooting accuracy of the gun body 400, enables the firearm clamp to adapt to different shooting scenes, and the shooting experience is more personalized, comfortable and efficient.

[0053] It can be understood that the gun tail positioning mechanism 220, the gun head 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 uses the butt portion as the initial positioning reference, the gun head positioning mechanism 230 and / or the grip positioning assembly 240 can be set to be adjustable relative to the connecting seat 110, thereby achieving adaptation to gun bodies 400 of different specifications. Similarly, when the gun body 400 uses the grip portion as the initial positioning reference, the gun tail positioning mechanism 220 and / or the gun head positioning mechanism 230 can be set to be adjustable relative to the connecting seat 110. If only the gun tail positioning mechanism 220 or the gun head positioning mechanism 230 is set to be adjustable relative to the connecting seat 110, the positioning structure that cannot be adjusted relative to the connecting seat 110 will not be elaborated here as long as it can ensure that it is applicable to gun bodies 400 of most specifications.

[0054] In a preferred embodiment, as shown in FIG. 1 to FIG. 7 , the gun further includes a buttstock shock absorbing assembly 300 disposed on the clamping frame and located on a side of the gun tail positioning mechanism 220 away from the gun head positioning mechanism 230 and the grip positioning assembly 240 .

[0055] The buttstock shock-absorbing assembly 300 is used to buffer the recoil of the buttstock portion of the gun body 400 .

[0056] In an embodiment of the present application, the above-mentioned adjustable firearm clamp is used. Since the gun body 400 will generate vibration and recoil when shooting, the butt shock absorber assembly 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 shooting, and further improving its shooting accuracy.

[0057] In a preferred embodiment, as shown in FIG. 1 to FIG. 7 , the clamping frame includes a support frame 200 rotatably disposed on the engaging seat 110 and at least one guide rod 210 disposed on the support frame 200 .

[0058] Among them, the gun tail positioning mechanism 220 , the gun head positioning mechanism 230 , the grip positioning assembly 240 , and the gun stock shock absorbing assembly 300 are fixedly connected to the guide rod 210 .

[0059] In a preferred embodiment, as shown in Figures 1 to 7, the gun stock shock absorbing assembly 300 includes a fixing seat 310 fixedly connected to the guide rod 210, an adjusting column 320 slidably set on the fixing seat 310, and a gun stock shock absorbing spring 330 set between the adjusting column 320 and the fixing seat 310.

[0060] Among them, the adjustment column 320 is parallel to the guide rod 210 and at least one is provided on the fixed seat 310. The adjustment column 320 is provided with a support column 340 that can abut the butt portion of the gun body 400 at one end close to the gun tail positioning mechanism 220. The butt shock-absorbing spring 330 can drive the support column 340 to move toward the side close to the gun body 400 under the action of its own elastic potential energy.

[0061] In a preferred embodiment, as shown in FIG. 1 to FIG. 7 , an automatic firing device 600 fixedly connected to the clamping frame and used to automatically control the gun body 400 for firing is also included.

[0062] It can be understood that after the gun body 400 is positioned on the clamping frame, the automatic firing device 600 can automatically release the safety of the gun body 400 and automatically trigger the trigger. Combined with the shooting angle control of the gun body 400 by the clamp, automatic shooting control of the gun body 400 can be performed without manual intervention, greatly improving the efficiency and safety of firearms shooting operations.

[0063] Example 2

[0064] As shown in FIG. 1 to FIG. 4 , an embodiment of the present application provides an adjustable firearm clamp, which includes the structural features of the aforementioned embodiment 1.

[0065] The pitch adjustment assembly includes a cylinder 500 hingedly mounted on the rotation output end of the turntable mechanism 100 , and a telescopic end of the cylinder 500 is hingedly connected to the clamping frame.

[0066] In an embodiment of the present application, the above-mentioned adjustable firearm clamp is adopted. When the cylinder 500 is extended and retracted, 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 shooting process, if the gun body 400 has an up and down lifting 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 telescopic damping provided by the cylinder 500 can reduce the lifting movement of the gun body 400 under the action of recoil, thereby making the gun more stable.

[0067] It is understandable that the arrangement of the pitch adjustment assembly is not limited to the above-mentioned one, as long as the pitch angle control of the gun body 400 can be achieved, which will not be elaborated here.

[0068] In a preferred embodiment, as shown in Figures 1 to 4, the guide rod 210 is slidably set on the support frame 200, and two threaded parts are threadedly connected on the guide rod 210. The two threaded parts can respectively contact the opposite end surfaces of the support frame 200 in the axial direction of the guide rod 210, thereby achieving the fixation of the guide rod 210 on the support frame 200.

[0069] Among them, the gun tail positioning mechanism 220 is fixedly set on the support frame 200, and the gun head positioning mechanism 230 and the grip positioning assembly 240 are set on the guide rod 210. When the screw parts on the guide rod 210 loosen 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 the relative position with the gun tail positioning mechanism 220, thereby achieving adaptation to gun bodies 400 of different specifications.

[0070] In a preferred embodiment, as shown in FIG. 1 to FIG. 4 , the gun head positioning mechanism 230 is fixedly disposed on the guide rod 210 , and the grip positioning assembly 240 is slidably disposed on the guide rod 210 .

[0071] The guide rod 210 is threadedly connected with two threaded members, which can respectively abut against opposite end surfaces of the handle positioning assembly 240 in the axial direction of the guide rod 210 , thereby fixing the handle positioning assembly 240 on the guide rod 210 .

[0072] It can be understood that after the butt portion of the gun body 400 is limited by the tail positioning mechanism 220, the distance between the gun head 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 butt portion and the gun head portion of the gun body 400, and by adjusting the relative position of the grip positioning assembly 240 on the guide rod 210, the position of the grip portion of the gun body 400 can be adapted, thereby achieving comprehensive limitation of the butt portion, gun head portion, and grip portion of the gun body 400.

[0073] It is understandable that the configuration of the gun tail positioning mechanism 220 , the gun head positioning mechanism 230 , and the grip positioning assembly 240 is not limited to the above-mentioned one, as long as the relative positions can be adjusted accordingly based on the specifications of the gun body 400 , which will not be elaborated here.

[0074] In a preferred embodiment, as shown in FIG. 1 to FIG. 4 , the gun tail positioning mechanism 220 includes a gun tail pressing plate 221 rotatably disposed on the support frame 200 and a first locking portion 223 for locking the gun tail pressing plate 221 in a fastened state.

[0075] It can be understood that when the butt portion of the gun body 400 is placed on the clamping frame, the butt pressure plate 221 can be rotated and engaged to press the end face of the butt portion of the gun body 400 away from the clamping frame. When the first locking portion 223 locks the engaged state of the butt pressure plate 221, the butt portion of the gun body 400 is locked.

[0076] In a preferred embodiment, as shown in FIG. 1 to FIG. 4 , a first hinge 222 is fixedly provided 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 via the first hinge 222 .

[0077] In a preferred embodiment, the gun tail pressure plate 221 is provided with retractable clamping parts on both sides of the gun body 400. When the gun tail pressure plate 221 is buckled, the side of the gun body 400 can be further clamped and limited by adjusting the clamping parts, thereby improving the clamping reliability of the gun body 400.

[0078] In a preferred embodiment, as shown in Figures 1 to 4, the gun tip positioning mechanism 230 includes a second base 234 fixedly provided on the guide rod 210, a gun tip pressure plate 231 rotatably provided on the second base 234, and a second locking portion 233 for locking the gun tip pressure plate 231 in a buckled state.

[0079] It can be understood that when the gun head part of the gun body 400 is placed on the clamping frame, the gun head part of the gun body 400 can be pressed against the end face of the side away from the clamping frame by rotating and fastening the gun head pressure plate 231. When the second locking part 233 locks the fastening state of the gun head pressure plate 231, the gun head part of the gun body 400 is locked.

[0080] In a preferred embodiment, as shown in FIG1 to FIG4 , a second hinge 232 is fixedly provided between the gun head pressing plate 231 and the second base 234 , that is, the gun head pressing plate 231 is rotatably connected to the second base 234 via the second hinge 232 .

[0081] In a preferred embodiment, the gun head pressure plate 231 is provided with retractable clamping parts on both sides of the gun body 400. When the gun head pressure plate 231 is buckled, the side of the gun body 400 can be further clamped and limited by adjusting the clamping parts, thereby improving the clamping reliability of the gun body 400.

[0082] In a preferred embodiment, as shown in Figures 1 to 4, the handle positioning assembly 240 includes a positioning fork frame 243 fixedly connected to the guide rod 210, a connecting plate 241 rotatably set on the positioning fork frame 243, a limiting fork frame 248 fixedly set on the connecting plate 241, and a locking assembly for swinging and locking the connecting plate 241.

[0083] The locking assembly includes a limiting screw 246 hingedly arranged on the positioning fork frame 243, a limiting nut 247 threadedly connected to the limiting screw 246, and a travel groove for the limiting screw 246 to pass through on the limiting fork frame 248.

[0084] Among them, when the grip positioning assembly 240 is locked, the grip of the gun body 400 is located between the positioning fork frame 243 and the limiting fork frame 248, the limiting screw 246 is located in the travel groove of the limiting fork frame 248 and the limiting nut 247 is in contact with the end face of the limiting fork frame 248 away from the positioning fork frame 243.

[0085] It can be understood that when the grip positioning assembly 240 is not locked, the limiting fork frame 248 is in an open state. At this time, the grip of the gun body 400 can be placed between the positioning fork frame 243 and the limiting fork frame 248. When the grip positioning assembly 240 is locked, the limiting fork frame 248 is rotated to make it abut the grip of the gun body 400. At this time, the limiting screw 246 is rotated into the travel groove of the limiting fork frame 248, and the limiting nut 247 is rotated at the same time to make it abut the limiting fork frame 248. Under the abutment action of the limiting nut 247, the relative positions of the limiting fork frame 248 and the positioning fork frame 243 are fixed, thereby achieving the limitation of the grip part of the gun body 400.

[0086] In the embodiment of the present application, the above-mentioned adjustable firearm clamp is adopted, and the gun tail positioning mechanism 220, the gun head positioning mechanism 230, and the grip positioning assembly 240 can realize the rapid fixation and release of the gun body 400 through simple operation, greatly improving the loading and unloading efficiency of the gun body 400.

[0087] In a preferred embodiment, as shown in FIG. 1 to FIG. 4 , a third hinge 242 is fixedly provided between the connecting plate 241 and the positioning fork frame 243 , that is, the connecting plate 241 is rotatably connected to the positioning fork frame 243 via the third hinge 242 .

[0088] In a preferred embodiment, as shown in Figures 1 to 4, the grip positioning assembly 240 also includes a fixing plate 244 fixedly connected to the guide rod 210, and the positioning fork frame 243 is slidably set on the guide rod 210 and a grip shock-absorbing spring 245 is fixed between the fixing plate 244.

[0089] In an embodiment of the present application, the above-mentioned adjustable firearm clamp is adopted, and the grip shock-absorbing spring 245 can buffer the recoil of the grip part of the gun body 400 when shooting. Combined with the buffering of the butt part of the gun body 400 by the butt shock-absorbing assembly 300 and the pitch damping of the gun body 400 by the cylinder 500, all-round shock absorption of the gun body 400 when shooting can be achieved, which facilitates better control of the gun during shooting and provides a smoother and more accurate shooting environment.

[0090] In a preferred embodiment, as shown in FIG. 1 to FIG. 4 , the automatic firing device 600 is fixedly disposed on the connecting plate 241 .

[0091] In a preferred embodiment, as shown in FIG. 1 to FIG. 4 , the first locking portion 223 and / or the second locking portion 233 is specifically configured as a snap-fit ​​structure.

[0092] Example 3

[0093] As shown in FIG. 5 to FIG. 11 , an embodiment of the present application provides an adjustable firearm clamp, which includes the structural features of the aforementioned embodiment 1.

[0094] The connecting seat 110 includes a seat body 111 fixedly disposed on the rotation output end of the turntable mechanism 100 . An embedding portion 112 is fixedly disposed on the seat body 111 , and a tooth portion 113 is disposed on the embedding portion 112 .

[0095] 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 transmission shaft 730 is power-connected to the motor 720 . A driving gear 710 meshing with the tooth portion 113 is fixedly mounted on the transmission shaft 730 .

[0096] Among them, the embedded portion 112 is arc-shaped and the center of the circle is located on the rotation axis of the support frame 200. When the motor 720 drives the driving gear 710 to rotate through the transmission shaft 730, the driving gear 710 drives the support frame 200 to rotate relative to the connecting seat 110 under the meshing action of the tooth portion 113, thereby adjusting the pitch angle of the clamping frame.

[0097] In the embodiment of the present application, the above-mentioned adjustable firearm clamp is adopted, and the pitch adjustment component adopts a rack and pinion transmission mechanism, which can further improve the adjustment accuracy of the pitch angle of the gun body 400.

[0098] It is understandable that the structural form of the pitch adjustment assembly is not limited to the above one, as long as it can achieve the pitch angle adjustment of the gun body 400, which will not be described in detail here.

[0099] In a preferred embodiment, as shown in Figures 5 to 11, two embedded parts 112 are symmetrically provided on the base 111 about the gun body 400, and two driving gears 710 are fixedly provided on the transmission shaft 730. The two driving gears 710 are respectively engaged with the tooth parts 113 on the two embedded parts 112.

[0100] It is understandable that the above arrangement can ensure the force balance of the support frame 200 when the pitch adjustment assembly is driven, thereby improving the pitch adjustment stability of the gun body 400.

[0101] In a preferred embodiment, as shown in FIG. 5 to FIG. 11 , the support frame 200 is provided with a guide groove 201 that slidably cooperates with the embedding portion 112 .

[0102] It is understandable that the sliding fit between the guide groove 201 and the embedded portion 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 .

[0104] The locking assembly includes a travel groove provided on the limiting fork frame and used for the guide rod 210 to pass through, and a limiting nut is threadedly connected to the guide rod 210.

[0105] Among them, when the grip positioning assembly 240 is locked, the grip of the gun body 400 is located between the positioning fork frame and the limiting fork frame, the guide rod 210 is located in the travel groove of the limiting fork frame, and the limiting nut abuts against the end face of the limiting fork frame away from the positioning fork frame.

[0106] It can be understood that when the grip positioning assembly 240 is not locked, the limiting fork frame is in an open state. At this time, the grip of the gun body 400 can be placed between the positioning fork frame and the limiting fork frame. When the grip positioning assembly 240 is locked, the limiting fork frame is rotated to make it abut the grip of the gun body 400. At this time, the limiting nut is rotated to make it abut the limiting fork frame. Under the abutting action of the limiting nut, the relative positions of the limiting fork frame and the positioning fork frame are fixed, thereby achieving the limitation of the grip part of the gun body 400.

[0107] In a preferred embodiment, as shown in FIG. 5 to FIG. 7 , the automatic firing device 600 is fixedly mounted on the connecting plate.

[0108] In a preferred embodiment, as shown in FIG. 5 to FIG. 7 , the gun tail positioning mechanism 220 and the gun head positioning mechanism 230 are configured to be able to adjust their relative positions with the engaging seat 110 .

[0109] It can be understood that the grip positioning assembly 240 is fixedly set on the guide rod 210. After the grip part of the gun body 400 is limited by the grip positioning assembly 240, the adaptation of the butt part and the gun head part of the gun body 400 can be achieved by adjusting the relative positions of the gun tail positioning mechanism 220, the gun head positioning mechanism 230 and the grip positioning assembly 240 respectively.

[0110] In a preferred embodiment, as shown in Figures 5 to 7 and 10, 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 portion 223 for locking the gun tail pressure plate 221 in a buckled state.

[0115] In the embodiment of the present application, the above-mentioned adjustable firearm clamp is adopted. When the butt portion of the gun body 400 is placed on the first platform 225, the downward pressure of the gun body 400 will drive the first platform 225 to move away from the tail pressure plate 221, thereby driving the second rocker arm 228 to swing through the first connecting rod 226, and then driving the two first clamping plates 229 to move toward the side close to the gun body 400 to achieve lateral clamping and limiting of the gun body 400.

[0116] In a preferred embodiment, as shown in FIG5 to FIG7 and FIG10, 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 disposed on the movable end of the first base 224.

[0117] It is understandable that the distance between the gun tail pressure 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 buttstock of the gun body 400 of different specifications and ensuring the clamping and limiting effect of the buttstock part of the gun body 400.

[0118] In a preferred embodiment, self-locking buckle components are respectively provided on the opposite side end surfaces of the two first clamping plates 229, and the engaging ends of the two self-locking buckle components can be adjusted in position in the longitudinal direction and engaged with each other.

[0119] It can be understood that after the gun body 400 is positioned under the clamping action of the two first clamping plates 229, the clamping ends of the two self-locking snap-fit ​​assemblies can be adjusted according to the height of the clamping position of the gun body 400, wherein the opposite movement of the two first clamping plates 229 can drive the clamping ends of the two self-locking snap-fit ​​assemblies to contact each other and complete the self-locking clamping. When dismantling, you only need to release the lock, which will not be elaborated here.

[0120] In a preferred embodiment, as shown in Figures 5 to 7 and 11, the gun tip positioning mechanism 230 includes a second base 234 fixedly connected to the guide rod 210, a gun tip pressure plate 231 rotatably arranged on the second base 234, and a second locking portion 233 for locking the gun tip pressure plate 231 in a buckled state.

[0121] It can be understood that when the gun head part of the gun body 400 is placed on the second base 234, the gun head part of the gun body 400 can be pressed against the end face of the gun head part away from the second base 234 by rotating and fastening the gun head pressure plate 231. When the second locking part 233 locks the fastening state of the gun head pressure plate 231, the gun head part of the gun body 400 is locked.

[0122] In a preferred embodiment, as shown in Figures 5 to 7 and 11, the gun tip positioning mechanism 230 also includes a second platform 235 for supporting the bottom of the gun tip of the gun body 400 and two second clamps 239 for respectively limiting the two side surfaces of the gun tip of the gun body 400.

[0123] 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 a corresponding position. The third swing rod 237 and the fourth swing rod 238 on the corresponding sides are parallel to each other.

[0124] A second link 236 is hingedly provided at the middle of the fourth swing link 238 , and an end of the second link 236 away from one side of the fourth swing link 238 is hingedly connected to the corresponding end of the second platform 235 .

[0125] In an embodiment of the present application, the above-mentioned adjustable firearm clamp is adopted. When the gun head part of the gun body 400 is placed on the second platform 235, the downward pressure of the gun body 400 will drive the second platform 235 to move away from the gun head pressure plate 231, thereby driving the fourth rocker arm 238 to swing through the second connecting rod 236, and then driving the two second clamping plates 239 to move toward the side close to the gun body 400 to achieve lateral clamping and limiting of the gun body 400.

[0126] In a preferred embodiment, as shown in Figures 5 to 7 and 11, 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 disposed on the movable end of the second base 234.

[0127] It is understandable that the distance between the gun head pressure plate 231 and the second carrier 235 can be adjusted by raising and lowering the telescopic end of the second base 234, thereby matching the gun head height of gun bodies 400 of different specifications and ensuring the clamping and limiting effect of the gun head part of the gun body 400.

[0128] In a preferred embodiment, as shown in Figures 5 to 7 and 11, the second carrier 235 has a guide column portion that is slidably connected to the second base 234. When the gun body 400 is pressed downward to drive the second carrier 235 to move toward the side away from the gun head pressure plate 231, the guide column portion of the second carrier 235 can improve the movement stability of the second carrier 235, thereby ensuring the clamping consistency of the two second clamps 239.

[0129] It is understandable that the structures of the gun tail positioning mechanism 220 and the gun head positioning mechanism 230 are not limited to the above-mentioned ones, as long as they can achieve rapid clamping and limiting of the buttstock and gun head of the gun body 400, which will not be described in detail here.
