Therefore, in such a situation, the operator can only protect himself and cannot effectively subdue the dangerous person.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0005] In view of the shortcomings of the above-mentioned prior art, the purpose of the utility model is to provide a restraining steel fork to solve the problem in the prior art that the operator forks a dangerous person in a single position, the dangerous person resists fiercely, there is still a risk of injury, and the dangerous person cannot be effectively subdued.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A restraining steel fork;

[0008] It includes: a restraint belt; a gripping rod; a fork, which is arranged on the gripping rod; and a pulling piece, which is movably arranged on the gripping rod; wherein the pulling piece is connected to the middle position of the restraint belt; when the restraint belt is in an unfolded state, the two ends of the restraint belt are detachably arranged on the fork; when the restraint belt is in a wound state, the two ends of the restraint belt are opened and closed and connected.

[0009] A further technical solution is that the constraint belt includes: a first elastic plate; a second elastic plate movably connected to the first elastic plate; a belt body wrapping the first elastic plate and the second elastic plate; wherein the winding directions of the first elastic plate and the second elastic plate are the same.

[0010] A further technical solution is that the restraint belt further includes: a buffer portion, which is arranged in parallel on one side of the first elastic plate in the winding direction.

[0011] A further technical solution is that connectors are provided at both ends of the first elastic plate; and the connectors are plugged into the fork head.

[0012] A further technical solution is that a fastener is swingably arranged in the fork head; a first elastic device is arranged at the swinging position of the fastener; the first elastic device pushes the fastener to buckle the connecting head; a pulling member is movably arranged in the fork head; and the pulling member is respectively connected to the fastener and the pulling member.

[0013] A further technical solution is that the pulling member includes: a toggle rod movably arranged on the holding rod; a second elastic device arranged in the holding rod; a pull rope respectively connecting the toggle rod and the restraint belt; wherein the second elastic device elastically pushes the toggle rod.

[0014] A further technical solution is that the pull rope passes through the restraining belt of the pull block; a pull groove is provided on the pull block; and the first elastic plate and the second elastic plate are placed in the pull groove.

[0015] A further technical solution is that a rod body is rotatably arranged on the toggle rod; a notch is opened on the toggle rod; a pressure plate is swingably arranged in the notch; a third elastic device is arranged at the swinging position of the pressure plate; the pull rope is placed in the notch and wrapped around the rod body; and the third elastic device pushes the pressure plate to press the pull rope.

[0016] A further technical solution is that an extension edge is provided at one end of the first elastic plate; a magnet is provided on the extension edge; and when the restraint belt is in a wound state, the magnet is magnetically connected to the other end of the first elastic plate.

[0017] Compared with the prior art, the beneficial technical effects of the utility model are as follows: (1) when the restraint belt is in a wound state, the restraint belt bends, and the two ends of the restraint belt are opened and closed to prevent the target from breaking free; after the restraint belt is wound around the target, the pulling member is still connected to the restraint belt, and the target can be pulled and controlled by controlling the grip rod to drive the fork to move; and the target is forked by moving the fork to limit the movement of the target, thereby completing the re-subjugation of the target; the restraint steel fork can limit the target to one position through the restraint belt, and then subdue the target to another position through the fork, which can effectively subdue the target and prevent the target from breaking free.

[0018] (2) The target is contacted by the buffer part to avoid being pinched when the restraint belt is wound around it; when the target is relatively thin, there is a gap between the restraint belt and the target when the restraint belt is wound around it, and the target can easily escape. The target can be completely trapped by contacting the target by the buffer part.

[0019] (3) By toggling the toggle lever to move along the holding lever, the toggle lever pulls the pull rope, and the pull rope pulls the middle position of the restraint belt, accelerating the two ends of the restraint belt to approach each other, completing the rapid winding of the restraint belt; at the same time, the pull rope pulls the restraint belt to prevent the restraint belt from being separated from the fork head by a long distance; after the restraint belt is wound around the target, the toggle lever is released, and the second elastic device elastically pushes the toggle lever to reset, and the pull rope extends out of the fork head by a long distance. At this time, the fork head can be moved to complete the re-subduing of the target.

[0020] (4) After the restraint belt is wrapped around the target, the target may still resist. In order to facilitate the movement of the fork, the length of the pull rope needs to be extended. As long as the force of moving the fork is greater than the force of the pressure plate pressing the pull rope, the rod body will rotate, and the pull rope will move out of the fork after passing through the notch, so that the distance the pull rope extends out of the fork is extended, and the fork can be moved to complete the re-subduing of the target.

According to the following description, the advantages and features of the utility model will be clearer. It should be noted that the accompanying drawings adopt a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the implementation method of the utility model. In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, please refer to the accompanying drawings. It should be noted that the structure, proportion, size, etc. illustrated by the accompanying drawings of this specification are only used to match the content disclosed in the specification, so that people familiar with this technology can understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so it has no technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect that the utility model can produce and the purpose that can be achieved, should still fall within the scope of the technical content disclosed by the utility model.

[0027] Figure 1 The following is a schematic diagram showing the structure of the restraining steel fork according to an embodiment of the utility model. Figure 1 As shown, the utility model discloses a restraining steel fork.

[0028] The restraint steel fork comprises: a gripping rod 1, a fork head 2, a restraining belt 3 and a pulling piece 4. The fork head 2 can be welded and fixed on the gripping rod 1, or the fork head 2 can be threadedly connected to the gripping rod 1. The pulling piece 4 is movably arranged on the gripping rod 1, and the pulling piece 4 can move along the gripping rod 1.

[0029] After the pulling member 4 extends out of the gripping rod 1, it is connected to the middle position of the restraint belt 3. When the restraint belt 3 is in the unfolded state, the two ends of the restraint belt 3 are detachably arranged on the fork 2. The fork 2 pulls the two ends of the restraint belt 3 so that the restraint belt 3 is maintained in the unfolded state.

[0030] When the restraint steel fork needs to subdue the target, the gripping rod 1 is held, the fork head 2 and the restraint belt 3 are brought close to the target, and the pulling piece 4 is pulled, and the pulling piece 4 drives the restraint belt 3 to be wound around the target.

[0031] When the restraint belt 3 is in the wound state, the restraint belt 3 is bent, and the two ends of the restraint belt 3 are opened and closed to prevent the target from escaping.

[0032] The targets in this application include: criminals, drunkards, patients with mental or infectious diseases and other dangerous persons. They also include aggressive large animals.

[0033] After the restraint belt 3 is wound around the target, the pulling member 4 is still connected to the restraint belt 3, and the target can be pulled and controlled by controlling the gripping rod 1 to drive the fork 2 to move. And the target is forked by moving the fork 2 to restrict the movement of the target, and the target is subdued again. The restraint steel fork can restrict the target at one position through the restraint belt 3, and then subdue the target at another position through the fork 2, which can effectively subdue the target and prevent the target from escaping.

[0034] Figure 2 Shows Figure 1 Enlarged structural diagram of point A in the middle. Figure 3 Shows Figure 1 The enlarged structure diagram of B in the middle. Figure 1-Figure 3 As shown, the restraining belt 3 includes: a first elastic plate 31, a second elastic plate 32 and a belt body 33. The two ends of the second elastic plate 32 are connected to the surface of the first elastic plate 31. The second elastic plate 32 is movably connected to the back side of the first elastic plate 31 in the winding direction. The second elastic plate 32 is movably connected to the first elastic plate 31 through a pin. The pin is set at both ends of the second elastic plate 32, and the pin passes through the back side of the first elastic plate 31 in the winding direction.

[0035] The belt body 33 is woven to wrap the first elastic plate 31 and the second elastic plate 32 .

[0036] The first elastic plate 31 and the second elastic plate 32 have the same winding direction.

[0037] The second elastic plate 32 increases the winding force of the first elastic plate 31 , so that after the restraining belt 3 is wound around the target, the target cannot break free from the restraining belt 3 .

[0038] The restraint belt 3 also includes: a buffer portion 35. The buffer portions 35 are arranged in parallel on one side of the winding direction of the first elastic plate 31. There are gaps between adjacent buffer portions 35 to avoid interference between adjacent buffer portions 35 after the restraint belt 3 is wound. Exemplarily, the buffer portion 35 is made of sponge material. The buffer portion 35 contacts the target to avoid pinching the target when the restraint belt 3 is wound. When the target is relatively thin and small, there is a gap between the restraint belt 3 and the target when the restraint belt 3 is wound around the target, and the target can easily escape. The buffer portion 35 contacts the target to completely trap the target.

[0039] Connectors 34 are provided at both ends of the first elastic plate 31. When the restraint belt 3 is installed on the fork head 2, the connector 34 is plugged into the fork head 2.

[0040] A fastener 21 is swingably arranged in the fork head 2. A first elastic device 23 is arranged at the swinging position of the fastener 21. Exemplarily, the first elastic device 23 is a spring. A step is formed on the connecting head 34, and the first elastic device 23 pushes the fastener 21 to buckle the step of the connecting head 34. A pulling member 22 is movably arranged in the fork head 2. The pulling member 22 is respectively connected to the fastener 21 and the pulling member 4.

[0041] After the pulling member 4 is pulled, the pulling member 4 pulls the pulling member 22 and the fastener 21 in sequence, the fastener 21 is separated from the connecting head 34 and no longer restricts the connecting head 34, and the restraint belt 3 is wound.

[0042] Figure 4 Shows Figure 1 The enlarged structure diagram at C in the middle. Figure 1-Figure 4 As shown, the pulling member 4 includes: a pull rope 43, a toggle rod 41 movably arranged on the gripping rod 1, and a second elastic device 42 arranged in the gripping rod 1. Exemplarily, the second elastic device 42 is a spring. The toggle rod 41 extends out of the gripping rod 1 to facilitate the movement of the toggle rod 41.

[0043] The pull rope 43 is respectively connected to the toggle rod 41 and the restraint belt 3. The second elastic device 42 elastically pushes the toggle rod 41. The pulling member 22 is connected to the toggle rod 41.

[0044] By toggling the toggle rod 41 to move along the grip rod 1, the toggle rod 41 pulls the drawstring 43, and the drawstring 43 pulls the middle position of the restraint belt 3, accelerating the two ends of the restraint belt 3 to approach each other, completing the rapid winding of the restraint belt 3. At the same time, the drawstring 43 pulls the restraint belt 3 to prevent the restraint belt 3 from being separated from the fork 2 by a long distance. After the restraint belt 3 is wound around the target, the toggle rod 41 is released, and the second elastic device 42 elastically pushes the toggle rod 41 to reset, and the drawstring 43 extends out of the fork 2 by a long distance. At this time, the fork 2 can be moved to complete the re-subduing of the target.

[0045] The pull rope 43 constrains the belt 3 through the pull block 44. Two sets of pull grooves 45 are provided on the pull block 44. The middle position of the first elastic plate 31 and the middle position of the second elastic plate 32 are placed in each pull groove 45. Exemplarily, the pull groove 45 is an arc groove.

[0046] The pull rope 43 can pull the first elastic plate 31 and the second elastic plate 32 simultaneously through the pull block 44 , thereby accelerating the winding speed of the first elastic plate 31 and the second elastic plate 32 .

[0047] A rod body 46 is rotatably arranged on the toggle rod 41. The toggle rod 41 and the rod body 46 are perpendicular to each other. A notch 47 is provided at one end of the toggle rod 41 close to the restraining belt 3. A pressure plate 48 is swingably arranged in the notch 47. A third elastic device 49 is arranged at the swinging position of the pressure plate 48. Exemplarily, the third elastic device 49 is a spring. The pull rope 43 is placed in the notch 47 and is wound around the rod body 46. The third elastic device 49 pushes the pressure plate 48 to press the pull rope 43.

[0048] The force of the pressing plate 48 pressing the pull rope 43 is greater than the force of moving the toggle rod 41, so that when the toggle rod 41 is moved, the pressing plate 48 presses the pull rope 43, and the distance from the toggle rod 41 to the restraint belt 3 is fixed.

[0049] After the restraint belt 3 is wound around the target, the target may still resist. In order to facilitate the movement of the fork 2, the length of the pull rope 43 needs to be extended. As long as the force of moving the fork 2 is greater than the force of the pressure plate 48 pressing the pull rope 43, the rod body 46 rotates, and the pull rope 43 passes through the notch 47 and moves out of the fork 2, so that the distance that the pull rope 43 extends from the fork 2 is extended, the fork 2 can be moved, and the target can be subdued again.

[0050] An extension edge 36 is provided at one end of the first elastic plate 31, and the extension edge 36 is elastic. A magnet 37 is provided on the extension edge 36. When the restraint belt 3 is in a wound state, the extension edge 36 winds around the other end of the first elastic plate 31, and the magnet 37 magnetically connects to the other end of the first elastic plate 31. Through the magnetic attraction of the magnet 37, the restraint belt 3 completely winds around the target, and the target cannot break free from the restraint belt 3.

[0051] In the present application, in addition to magnetically connecting the first elastic plate 31 by means of the magnet 37, the two ends of the first elastic plate 31 can also be connected by means of Velcro. The hairy surface and the hook surface of the Velcro are respectively arranged at the two ends of the belt body 33. After the first elastic plate 31 is wound, the hairy surface and the hook surface of the Velcro on the belt body 33 adhere to each other, so that the restraint belt 3 completely wraps around the target, and the target cannot break free from the restraint belt 3.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
