Description

Technical Field

[0001] This utility model belongs to the field of steel fork technology, specifically a multi-functional capture-type police steel fork. Background Technology

[0002] Currently, most police arrest forks are fixed structures with limited fork arm size and function, making them unsuitable for flexible replacement based on arrest scenarios (such as targeting suspects of different body types, confined indoor spaces, or open outdoor areas), resulting in poor adaptability. Furthermore, traditional forks rely solely on the encirclement effect of the fork arms to restrict suspect movement, lacking a secondary restraint mechanism. Suspects can easily escape by pulling back or adjusting their body posture to break free from the gaps between the fork arms, leading to low arrest efficiency and high safety risks. In addition, some adjustable restraint forks have complex adjustment operations, requiring multiple steps with both hands, making rapid response difficult during emergency arrests and affecting the control of the arrest timing. Therefore, we propose a multi-functional arrest police fork. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5A multi-functional capture-type police steel fork includes a support rod 1. A set of fork arms 18 are installed on both the left and right sides of the support rod 1. A set of limiting rods 2 are installed on opposite sides of the two sets of fork arms 18. Cross bolts 17 connect the fork arms 18 to the support rod 1. A hexagonal groove is formed on the rear side of the support rod 1. A limiting plate 16 is placed on the rear side of the support rod 1. A hexagonal rod 12 is fixedly installed on the front side of the limiting plate 16 and slidably disposed within the hexagonal groove. A first handle 14 is placed above the support rod 1. A second handle 15 is slidably disposed inside the first handle 14. A spring 151 and a pin 152 are fixedly installed at the bottom of the second handle 15. The pin 152 is inserted between the hexagonal rod 12 and the support rod 1. A guide sleeve 13 is fixedly installed at the bottom of the first handle 14 and slidably sleeved on the outside of the support rod 1. A guide plate 153 is fixedly installed on the top of the inner wall of the guide sleeve 13. Anti-slip rings 11 are evenly fixedly fitted on the outer side of the support rod 1. The user holds the part of the support rod 1 with anti-slip rings 11 on the outer side with their left hand, and holds the first handle 14 and the second handle 15 with their right hand. A guide groove is opened through the top of the hexagonal groove, and insertion holes are evenly opened through the bottom of the hexagonal groove. The anti-slip rings 11 are located behind the guide groove. The guide plate 153 is slidably set in the guide groove. The bottom of the pin 152 is designed with a rounded chamfer to make it easier for the pin 152 to pass through the insertion hole. A first through hole is opened through the bottom of the inner side wall of the first handle 14. The spring 151 is fixedly set between the first handle 14 and the second handle 15 and is located on the outer ring of the pin 152. The top of the guide sleeve 13 and the guide plate 153 are both opened through the second through hole. The top of the hexagonal rod 12 is opened through the third through hole. The top of the pin 152 is opened through the first through hole, the second through hole, the third through hole and the insertion hole.

[0016] A set of square holes is provided on both the left and right sides of the support rod 1. A set of connecting blocks 21 is fixedly installed on the opposite sides of the two sets of fork arms 18. The connecting blocks 21 are inserted into the square holes. A threaded hole is provided on the top of the connecting blocks 21. Two sets of countersunk holes are evenly provided on the top of the support rod 1. A cross bolt 17 passes through the countersunk hole and is screwed into the threaded hole. The connecting blocks 21 are inserted into the square holes of the support rod 1, and the cross bolts 17 pass through the countersunk hole of the support rod 1 and are screwed into the threaded hole of the connecting block 21, thereby fixing the connecting blocks 21 in the square holes of the support rod 1, and thus making the fork arms 18... After unscrewing the cross bolt 17, the fork arm 18 can be removed from the outside of the support rod 1. This allows for the selection of fork arms 18 of different sizes and functions according to actual usage requirements. A mounting block 19 is fixedly installed on the rear side of the fork arm 18. A set of mounting grooves is opened on the opposite sides of the two sets of mounting blocks 19. The mounting grooves penetrate the front side of the mounting blocks 19. A mounting hole is opened through the top of the limit rod 2. A support shaft 22 is rotatably installed in the mounting hole. The support shaft 22 is fixedly installed in the mounting groove. A torsion spring 23 is fixedly installed between the support shaft 22 and the mounting hole.

[0017] Working principle: Insert the connecting block 21 into the square hole of the support rod 1, and use a cross bolt 17 to thread the countersunk hole of the support rod 1 and the threaded hole of the connecting block 21 to fix the connecting block 21 in the square hole of the support rod 1, thereby fixing the fork arm 18 to the outside of the support rod 1. Hold the part of the support rod 1 with the anti-slip ring 11 on the outside with your left hand, and hold the first handle 14 and the second handle 15 with your right hand.

[0018] When the victim's waist enters between the two sets of fork arms 18, the limiting rod 2 will first be pushed forward around the center of the support shaft 22 and twist the torsion spring 23. After the victim's waist enters between the two sets of fork arms 18, the torsion spring 23 will use its own rebound force to drive the limiting rod 2 to flip backward and reset. In this way, the two sets of limiting rods 2 will limit the back of the victim's waist, thereby preventing the victim's waist from slipping out between the two sets of fork arms 18. At the same time, the user pulls the second handle 15 upward and makes the top of the second handle 15 fit against the top of the inner side wall of the first handle 14. At this time, the upward-moving second handle 15 will cause the pin 152 to move upward and separate from the insertion hole of the support rod 1, and move into the third through hole of the hexagonal rod 12. The second handle 15 will stretch the spring 151 and then push the first handle 14 backward against the guide plate 15. With the assistance of guide sleeve 13, the hexagonal rod 12 is driven to move backward steadily, which in turn drives the limiting plate 16 to move backward. This causes the backward-moving limiting plate 16 to press against the abdomen of the dangerous person located between the two sets of fork arms 18, thereby reducing the movement space of the dangerous person between the two sets of fork arms 18 and improving the capture efficiency. When the user releases the second handle 15 and moves the first handle 14 back and forth slightly, the spring 151 uses its own rebound force to carry the pin 152 through the insertion holes opened at different positions on the bottom of the support rod 1 using the second handle 15, thereby fixing the hexagonal rod 12 in the hexagonal groove of the support rod 1. This completes the position fixation of the limiting plate 16 on the rear side of the hexagonal rod 12. The bottom of the pin 152 is designed with a rounded chamfer, so that the pin 152 can be more easily passed through the insertion hole.

[0019] After unscrewing the cross bolt 17, the fork arm 18 can be removed, allowing for the replacement of fork arms 18 with different sizes and functions according to actual usage requirements.
