Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:
Embodiment one
As shown in Figure 1, police constraint fork in the present embodiment, comprise support bar 1, arrest ring 2, describedly arrest the first end that ring 2 is arranged on described support bar 1, arrest ring 2 and be provided with opening, described opening part arranges at least one limited block 4, described ring 2 of arresting is rotatably connected with limited block 4, each limited block 4 arranges a torsion spring matched 3, arrest described in described torsion spring 3 is fixed on ring 2, and described torsion spring 3 one end hook with arrest ring 2 and be fixedly connected with, other end hook is fixedly connected with described limited block 4, described torsion spring 3 makes limited block 4 rotate to arresting in ring 2 to produce and to return its initial position.Above-mentioned police constraint fork, limited block 4 is made to rotate to arresting in ring 2 to produce and to return its initial position by the torsion spring 3 arranged, described initial position can be angled with opening or concordant, but must meet suspect can not from arresting the requirement escaped ring 2, when arresting, the health that the personnel that arrest only need aim at suspect carries out one and pushes away an action of drawing, suspect will fall into and arrests ring 2 and fettered, enable to arrest personnel and effectively control suspect in safe distance, flexible to operation, guarantee to arrest personnel's inherently safe, damage is significantly reduced.
Limited block 4 described in the present embodiment is two, and two limited blocks 4 are symmetricly set on the both sides of described opening, suspect is more easily fallen into and arrests ring 2 and be difficult to shake off from arresting ring 2, and it is better to arrest effect.Described ring 2 of arresting is provided with the first installing sleeve 5, and described first installing sleeve 5 is enclosed within the first end of described support bar 1 and is fixedly connected with support bar 1.Police constraint fork also comprises lever 6, and make the personnel that arrest can grip police constraint fork better, described lever 6 is provided with the second installing sleeve 7, and described second installing sleeve 7 is enclosed within the second end of described support bar 1 and is fixedly connected with support bar 1.Described support bar 1 overlaps with described first installing sleeve 5 respectively, the second installing sleeve 7 overlaps staking, is connected firmly, can not destroys workpiece, and reduces production cost, improves operating speed.
As shown in Figure 2,3, 4, support bar 1 in the present embodiment is provided with fold mechanism 8, described fold mechanism 8 comprises pedestal 81, rocking bar 82, locking folder 83, described rocking bar 82 is rotatably connected with pedestal 81, described locking folder 83 is hinged on rocking bar 82 by guide pillar 84, described pedestal 81 is also hinged with one piece of swivel plate 85, described swivel plate 85 is provided with snap fit 86, and described locking folder 83 can catch on described snap fit 86.As shown in Figure 2, during use, rotated by swivel plate 85 on pedestal 81, control rocking bar 82 thus locking is pressed from both sides 83 to catch on snap fit 86, now support bar 1 becomes a complete body of rod; As shown in Figure 3, time folding, locking folder 83 departs from snap fit 86, and swivel plate 85 is separated with pedestal 81, and now support bar 1 is divided into two, and is convenient to transport and preserves.
In the present embodiment arrest ring 2, lever 6 be arranged in parallel, arrest the stressed relatively more even of ring 2 and lever 6, can not distortion be produced.Described support bar 1, arrest ring 2, lever 6 adopts aluminium to make, and alleviates overall weight.The overall length of described support bar 1 is 1.5 meters-2.5 meters, ensures the distance of arresting between personnel and suspect, described in arrest ring 2 radius be 0.1 meter-0.15 meter, for fettering the four limbs of suspect.
