Technical Field
[0001] This utility model relates to the field of police equipment manufacturing technology, and in particular to a folding capture device. Background Technology
[0002] A capture device is a non-lethal close-range weapon primarily used to apprehend dangerous individuals such as criminals wielding sharp weapons, intoxicated persons, and those suffering from infectious or mental illnesses. This small, portable fork can quickly restrain a criminal's legs and hands wielding knives or batons, making it suitable for use in public security settings such as schools, hospitals, public transportation, and subways. As a restraining police device, the capture device holds an important position and role in police equipment.
[0003] However, in the process of implementing the utility model technical solution in the embodiments of this application, the applicant discovered that the above-mentioned technology has at least the following technical problems:
[0004] Traditional capture devices are relatively short and need to be lengthened. However, increasing the length makes storage and transportation inconvenient. This necessitates foldable capture devices. However, some foldable capture devices on the market are cumbersome to fold and fix, and cannot meet current needs.
[0005] The capture device's opening and closing size is insufficient, and its weight is relatively heavy, resulting in limitations in its use when encountering larger criminals. Adjustments to the opening and closing size and weight of the capture device are needed to meet market demands. Utility Model Content
[0006] This application provides a folding capture device. By incorporating an extension rod, the extension rod can be easily installed and connected via hinges and connectors, making operation convenient and secure. This effectively increases the usable length of the capture device and expands its capture range. Multiple linkages enable the tightening and releasing of the grippers, saving officers' effort during retraction and release. The opening size of the grippers is increased, and the restraint fork can be applied to various parts of the body, making it widely applicable and significantly reducing the weight of the multi-joint clamp head. The increased length of the restraint fork further enhances the restraint range.
[0007] This application provides a folding catcher, comprising: a multi-joint clamp head, which is fixed to one end of a main rod by bolts; a core rod is provided inside the main rod; a backstop groove is provided on one side of the core rod; fixing members are welded to both sides of the upper end of the core rod; the fixing members are movably connected to the multi-joint clamp head by bolts and nuts; the fixing members cooperate with a sliding groove on the main rod; a sliding sleeve is provided on the fixing members; a push rod device is fixed to the lower end of the core rod by fixing bolts; a locking member is provided on the push rod device that cooperates with the backstop groove; the locking member is movably fixed to the push rod device by a pin and a spring; an extension rod is fixed to the bottom end of the main rod by a hinge; a connecting member is provided on the extension rod; the connecting member includes a telescopic sleeve and a telescopic rod; the telescopic rod is connected and fixed to the telescopic sleeve by a screw; a limiting groove is provided on the extension rod that cooperates with the screw; a spring is provided inside the extension rod that cooperates with the telescopic rod; and the telescopic rod cooperates with a fixing groove at the bottom end of the main rod.
[0008] The multi-joint pliers head includes a gripper, an S-shaped linkage bar, an L-shaped linkage bar, a strip-shaped linkage bar, and an arc-shaped linkage bar. The top of the main rod is fixed with an assembly by bolts. The assembly connects and fixes two arc-shaped linkage bars by bolts. The bottom of the connector is provided with a support plate.

[0018] The multi-joint pliers head uses multiple linkage bars to achieve the tightening and releasing of the grippers, which can save the force of the police officers' hands when retracting and releasing. The opening size of the grippers is increased by 1 / 3-1 / 4 compared with the opening size of traditional capture devices. The capture device can be applied to various parts of the human body and has a wide range of practicality. By setting the strip hole, the weight of the multi-joint pliers head is greatly reduced, and the overall weight is about 3 / 4 of that without the strip hole.
[0019] The multi-joint pliers head is opened and clamped by a push rod device. The push rod device can effectively control the locking and fixing of the multi-joint pliers head through the cooperation of the locking part and the anti-reverse groove. It is simple to operate and convenient to use. Attached Figure Description

[0028] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:
[0029] An extension rod 5 is added, which can be folded for storage when not in use, saving space. When in use, the extension rod 5 can be installed and spliced through the hinge 4 and the connector 6. The hinge 4 and the connector 6 fix and limit the extension rod 5, making operation convenient and secure, effectively increasing the usable length of the catcher and improving the catching range. The multi-joint clamp head 1 is opened and clamped through the push rod device 3. The push rod device 3 can effectively control the locking and fixing of the multi-joint clamp head 1 through the cooperation of the locking part 301 and the anti-reverse groove 8. The operation is simple and convenient. Example
[0030] A folding catcher, wherein the multi-joint clamp head 1 includes a gripper 101, an S-shaped linkage bar 102, an L-shaped linkage bar 103, a strip-shaped linkage bar 105, and an arc-shaped linkage bar 104. The top of the main rod 2 is fixed with an assembly by bolts. The assembly connects and fixes two arc-shaped linkage bars 104 by bolts. The bottom of the connector 6 is provided with a support plate 107. The support plate 107 and the connector 6 are an integrated structure. The support plate 107 is close to the arc-shaped linkage bar 104 to support the arc-shaped linkage bar 104.
[0031] The arc-shaped linkage bar 104 has S-shaped linkage bars 102 staggered at its left and right ends, one arc-shaped linkage bar 104 close to the front and the other arc-shaped linkage bar 104 close to the rear. The S-shaped linkage bar 102 and the arc-shaped linkage bar 104 are movably connected. The S-shaped linkage bar 102 is fixed at a position 1 / 4-1 / 5 below the arc-shaped linkage bar 104. There are two support members between the S-shaped linkage bar 102 and the arc-shaped linkage bar 104. The support members are hourglass-shaped in shape.
[0032] One end of the S-shaped linkage bar 102 is movably connected to the gripper 101, and the other end is movably connected to the strip linkage bar 105. The connection position of the S-shaped linkage bar 102 and the gripper 101 is located at 1 / 5-1 / 6 of the gripper 101. The strip linkage bar 105 is movably connected to the slider.

[0033] The gripper 101, S-shaped linkage bar 102, L-shaped linkage bar 103 and strip linkage bar 105 are uniformly provided with strip-shaped holes, and the arc-shaped linkage bar 104 is provided with diamond-shaped holes 106. The diamond-shaped holes 106 are matched with bolts of various sizes, and the bolts can be tightened or loosened through the diamond-shaped holes 106.
[0034] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:
[0035] The multi-joint clamp head 1 achieves tightening and releasing through the cooperation of multiple linkage bars, which can effectively save the force required by police officers when using the arresting device. After multiple tests, compared with traditional arresting devices, this application can save 20%-40% of the force, making it suitable for widespread use. Through the cooperation of multiple linkage bars, the opening size of the gripper 1011-5 is increased by 1 / 3-1 / 4 compared with the opening and closing size of traditional arresting devices, making it applicable to various parts of the human body.
[0036] A connector 6 is provided, which is used in conjunction with bolts to fix the arc-shaped linkage plate. A support plate 107 is provided on the connector 6, which not only fixes it firmly, but also supports the arc-shaped linkage plate and improves its stability. The support members between the arc-shaped linkage plates can effectively prevent the deformation of the arc-shaped linkage plates and improve the stability of the connection between the arc-shaped linkage plate and the S-shaped linkage bar 102.
[0037] By setting the slotted hole, the weight of the multi-joint pliers head 1 is greatly reduced, and the overall weight is about 3 / 4 of that without the slotted hole.
[0038] Since the arc-shaped linkage bar 104 is located on the outermost side of the multi-joint pliers head 1, and a diamond-shaped hole 106 is provided on the arc-shaped linkage bar 104, the exposed bolts can be tightened or loosened using the catcher, which increases the functionality of the catcher.
[0039] The sliding sleeve 202 and the fixing member 201 are connected and fixed by bolts or welding. There is a gap between the sliding sleeve 202 and the main rod 2. The fixing member 201 drives the sliding sleeve 202 to slide up and down along the main rod 2. The slide groove is rectangular in shape and is set on both sides of the main rod 2. The width of the slide groove is greater than the thickness of the fixing member 201, and the length of the slide groove is half the length of the sliding sleeve 202.
[0040] The fixing bolt 304 moves along the movable groove 203 on the main rod 2. The main rod 2 is provided with an opening groove that cooperates with the locking member 301. The opening groove is located directly opposite the movable groove 203.
[0041] When the push rod device 3 is pushed to the top of the opening, the multi-joint pliers 1 opens as a whole; when the push rod device 3 is pushed to the bottom of the opening, the multi-joint pliers 1 tightens as a whole.
[0042] The extension rod 5 is provided with a handle 501 at its bottom end. The handle 501 is locked and fixed to the extension rod 5 by means of threads or bolts. The spring inside the extension rod 5 is provided on the outer ring of the telescopic rod 602, with its top end close to the extension rod 5 and its bottom end close to the telescopic rod 602.
[0043] The sliding sleeve 202 serves to prevent dust from entering the main rod 2 and provides a certain degree of protection for the fixing component 201.
[0044] The two sides of the main rod 2 are riveted with serrated strips, which serve to prevent theft.
[0045] Working principle: In use, the extension rod 5 is bent to the same straight position as the main rod 2 via hinge 4, and then the extension rod 5 and the main rod 2 are fixed and limited by the connector 6 (the telescopic sleeve 601 is pulled upward and then rotated to the right, the screw 603 moves along the limiting groove 604 and is limited, and the internal spring plays a role in resetting and fixing, preventing the telescopic sleeve 601 from moving). The telescopic rod 602 is driven by the telescopic sleeve 601 and extends into the fixing groove in the main rod 2. Through the limiting and fixing of the telescopic rod 602, the fixing groove and the hinge 4, the extension rod 5 and the main rod 2 can be tightly connected. After the rod 5 is installed, by holding the main rod 2 and the extension rod 5, the core rod 7 is moved by the moving push rod device 3. The movement of the core rod 7 causes the fixing part 201 to move up and down. The fixing part 201 causes the multi-joint pliers head 1 to clamp and open. When the multi-joint pliers head 1 moves to the corresponding position, by releasing the locking part 301, the spring on the locking part 301 and the spring on the core rod 7 will apply force, which will cooperate with the anti-reverse groove 8. The locking part 301 is limited by the anti-reverse groove 8 to prevent it from moving. By limiting it through the locking part 301 and the anti-reverse groove 8, the multi-joint pliers head 1 is fixed.
