The present invention relates to a firing device; more particularly, relates to a device for safe firing used in a tube of a rocket.
DESCRIPTION OF THE RELATED ARTSA shoulder-launched anti-armor rocket used by infantry has advantages on suitable weight, easy carry, strong firepower and wide application and thus is a good weapon for the infantry. The most common rockets include U.S.-made M72 and Russia-made RPG. These two are designed to be one-shot only and then be discarded, which have reliable performances and are widely used in nations. 66 anti-armor rocket is a variety of M72. It has only one safety design. If a user were lack of training or were under a high pressure in a battle field, he may press the trigger owing to nervousness and hurt people with misfire.
U.S. Pat. No. 4,417,498 reveals a firing device; but its structure is complex, its operation is complicated and it has vertical and horizontal components occupying big space.
Hence, the prior arts do not fulfill all users' requests on actual use.
SUMMARY OF THE INVENTIONThe main purpose of the present invention is to use a few safety designs to improve safety of a rocket tube during transportation and to prevent misfire owing to lack of training.
To achieve the above purpose, the present invention is a safe firing device used in a tube loaded with a rocket and comprises a primer seat, which is set at rear end of the tube for firing a motor of the rocket; a firing pin, which is set in front of the primer seat for hitting against the primer seat for firing the rocket; a rod, which is set in front of the firing pin for pushing the firing pin and is connected with the firing pin with an elastic unit; a cocking lever, which is set at a side of the tube for aiming the rod at the primer seat; a safety button, which is set at the side of the tube for locking and releasing the rod; and a trigger, which is set beneath the tube for controlling axial movement of the rod. Accordingly, a novel safe firing device is obtained.
The present invention will be better understood from the following detailed description of the preferred embodiment according to the present invention, taken in conjunction with the accompanying drawings, in which
The following description of the preferred embodiment is provided to understand the features and the structures of the present invention.
