The invention provides a collision trigger signal triggering device which comprises a trigger, a collision panel and a channel, wherein the trigger is arranged on a control panel, the control panel is connected with the channel through a flexible coupling, a magnet is arranged at the lower end of the control panel, and a conductive metal sheet is arranged at the lower end of an outlet of the channel and corresponds to the magnet. The collision panel is connected with the channel through the flexible coupling, so that the mobility of the signal triggering device can be effectively ensured, and the accuracy is improved. According to the collision trigger signal triggering device, through a mode that the magnet corresponding to the conductive metal sheet attracts with the conductive metal sheet, the signal conduction is ensured, when collision occurs, the magnet and the conductive metal sheet are disconnected to generate a jumping signal, so that a collision signal can be accurately and immediately sent, the triggering signal can be effectively, rapidly and accurately generated when a moving object reaches an end point of the movement channel, and unnecessary loss due to signal delay is avoided.
