Trigger two-stage safety device

The invention relates to a trigger two-stage safety device, in particular to a technology applied in the field of cross-bow. The main technique is to provide a smooth replacement of bows and arrows before the bow and arrow are fired, without causing a dangerous situation of random firing to achieve safety. The effect of protection is an excellent invention.

Bow and arrow is one of the famous sports events today, and more and more fans will go to the exclusive venue for the archery experience. Although the bow and arrow is a kind of sports, there is still a certain danger, so the relevant industry for the bow and arrow The design is equipped with a special insurance mechanism to prevent any dangerous situation.

There are also many kinds of bows and arrows, such as ancient string bows, recurve bows, compound bows, crossbows, etc. Various types of bows and arrows operate differently, but now they are discussing the crossbow, crossbow Anciently known as 弩 (Crossbow from English), it is a kind of shooting weapon. It is a kind of arm with an arm. It is mainly composed of the arm (body), the sacral bow (wing), the bowstring and the shovel. Because there is no need to aim at the same time when pulling the string, the requirements for the user are relatively low, but the time required for loading is much longer than that of the general bow and arrow. What is important is that the crossbow is farther than the normal bow and the lethality is more Strong, and the hit rate is higher. Therefore, many fans are very interested in the crossbow attempt. The common crossbow is used by pulling the bowstring to position and then opening the fuse, thereby preventing the empty string of the bowstring from being fired, and then positioning it after the upper crossbow arrow. After the insurance limit can be released, the trigger can be used to fire the board, and the cross-bow arrow is pushed forward toward the target by the instantaneous impulse of the bow string. The above is the basic cross-bow use mode.

There is another situation where the user has to change the size of the prey during the hunting process and must replace the crossbow arrow, but when the user After the crossbow arch has been placed on the bow, the safety connecting piece of the crossbow has been pushed by the safety slider to be stuck against the safety positioning block, and the displacement of the safety slider also releases the top of the limiting plunger. At this time, the crossbow is in a state where the trigger can be fired at any time. If the crossbow arrow is to be replaced at the moment, there will be a problem that the crossbow is already in the stunable state, and the user rushes to draw the crossbow. When the time is off, it is easy to break the string, and it is even possible to release the bow when the user pulls the crossbow. The restriction will cause the crossbow to be sent as scheduled, causing a dangerous situation of accidental injury. This situation will also occur when the crossbow arrow is damaged and must be replaced. If the crossbow arrow is to be replaced, the insurance must be turned on again. However, although the insurance slider of the safety slider can limit the firing, the front positioning insurance positioning block is continuously restricted because the safety connecting piece is not reset as scheduled, and there is a possibility that an empty string firing may occur. Therefore, the relevant industry must study and think again about the dangers caused by beginners, users, etc. in the process of replacing the crossbow.
