Thechute 13 is also provided with aninclined surface 14 that makes it easier for thefirst pulley block 21 a to travel along thechute 13 . Thebracket 12 is U-shaped, and thebracket 12 is also fixedly connected with thehandle 11 , and one end of the spring 5 is against theend surface 221 of theslot 23 . Thetransmission shaft 2 is connected with ahandle 25 . The projected shape of multiple firing paths connected on thetrack 3 is a parabola. Thetrack 3 is provided with atraveling surface 31 and a constrainingsurface 32 that prevents the second pulley set 21 b from running away from thetrack 3 . In this embodiment, therail 3 is in contact with the object to be fired as the final firing component, and therail 3 is usually provided with a power spring as a power device, and the object to be fired can be gauze or liquid medicine or the like.

本实施例的产品在动作时，拉动扳机1，使得第一滑轮组21a沿滑槽13行进，带动传动轴2整体向上抬举，同时限位销24从限位孔33内脱出，失去限位作用，连接在轨道3上的动力弹簧推动轨道3，第一滑轮组21a继续沿滑槽13行进并脱离滑槽13，第二滑轮组21b与轨道3上击发路径的最高点相接触，弹簧5被压缩，然后在弹簧5的作用下，使得第二滑轮组21b与轨道3上击发路径的最低点相接触，限位销24重新进入限位孔33内，如此完成一个运动周期，而轨道3也前进了一固定距离，实现了击发目的，如此往复。当所有的物品都击发完毕需要回位时，只需要拉起提手25，向上提拉传动轴2，并将轨道3拉回到原位，即可完成。本实施例的击发装置可用于击发各种类型的医疗用品包括药品、止血纱布、钛夹等，因此应用广泛。When the product of this embodiment is in action, thetrigger 1 is pulled, so that thefirst pulley block 21a advances along thechute 13, and drives thedrive shaft 2 to lift upwards as a whole, and at the same time, thelimit pin 24 comes out of thelimit hole 33, losing the limit function. The power spring connected on thetrack 3 pushes thetrack 3, the first pulley set 21a continues to advance along thechute 13 and breaks away from thechute 13, the second pulley set 21b contacts the highest point of the firing path on thetrack 3, the spring 5 is compressed, and then Under the action of the spring 5, thesecond pulley block 21b is in contact with the lowest point of the firing path on thetrack 3, and thelimit pin 24 re-enters thelimit hole 33, thus completing a movement cycle, and thetrack 3 also advances a fixed distance, the purpose of firing is achieved, and so on. When all items are fired and need to be returned, it is only necessary to pull up thehandle 25, lift thedrive shaft 2 upwards, and pull thetrack 3 back to its original position to complete. The firing device of this embodiment can be used to fire various types of medical supplies including medicines, hemostatic gauze, titanium clips, etc., so it is widely used.
