[0008] A pair of ejection rods are arranged side by side and one end of the ejection rods is inserted into the first installation cavity through the open mouth of the first installation cavity, and the ends of the pair of ejection rods located in the first installation cavity are connected by a connecting rope;
[0009] The ejection mechanism is arranged across the first installation cavity and the second installation cavity. It has an ejection end and is arranged in the first installation cavity and abuts against the ends of a pair of spring rods that penetrate into the first installation cavity. The ejection end outputs power to eject the pair of ejection rods out of the first installation cavity.
[0010] Furthermore, the ejection mechanism includes a trigger, a return spring, a connecting piece, a spring, a force storage spring, a blocking piece and a torsion spring. The upper part of one side of the trigger is rotatably connected to the upper part of the second mounting cavity, one end of the return spring is fixedly connected to the second mounting cavity, and the other end of the return spring is fixedly connected to the lower part of one side of the trigger. An extension portion is provided on the upper part of the trigger away from the return spring. The connecting piece is arranged in the first mounting cavity, and an inclined portion obliquely downward is provided at one end thereof close to the open mouth, and a horizontal bend is provided on the upper edge of the end of the inclined portion close to the trigger direction to form a connecting port with the inclined portion.

When the pair of ejection rods are ejected, the connecting ropes wrapped around the tail ends will be scattered due to speed difference or wind resistance. When the pair of ejection rods are swept to the object to be captured, due to the speed difference between the captured object and the ejection rod, the connecting rope on the ejection rod rotates around the captured object after touching the screen to the captured object, so that the connecting rope is wrapped around the captured object, which has the effect of hindering its rapid escape or resistance. In addition, it can ensure that the captured object is not directly harmed, greatly reducing the damage to both parties in the capture process, and also improving the capture efficiency. The security personnel only need to control the captured object in time when the captured object is disturbed by the ejection rod.
