The trap consists of an arrow (2), which passes through the guide (5). The arrow is propelled by a length of elastic (6). The guide is supported by a pedestal, which is fitted with a series of points (1), which are used to retain the guide in the required vertical or inclined position. A fine stem (8) passes from the trigger, which is fitted at the lower end (3) of the guide, and retains the large stem (7), which, in turn, retains the arrow. The arrow is fitted with a stop (9) on its upper end in such a way that the arrow is only driven around a maximum of 20 cm from the guide. A safety barrier (4) is fitted to protect children, when the trap is raised from the ground by more than 2 cm.
