Description

trigger reset device

This creation is about a trigger device, especially a crossbow trigger reset device.

Although the firing device of the existing crossbow can provide the effect of shooting the arrow body, and by pushing the safety switch, the firing device can be placed in an off-safety state that cannot be pressed, so as to prevent the arrow body from being shot due to accidentally touching the trigger. However, in the existing crossbow, when the bow string is stretched and hooked to the thread catcher, if the user accidentally touches the trigger when the bow and arrow are not placed in the firing device, the bowstring will be hooked to the hook The liner is separated and ejected forward, resulting in an empty shot, resulting in the energy of drawing the bow that cannot be converted into the speed of the arrow body, and can only be borne by the crossbow itself, so that the arms and strings of the crossbow may not be able to withstand the impact of this energy. Breaking not only shortens the service life of the crossbow, but also causes a safety hazard to the user or the surrounding personnel due to the sudden fracture of the bow arm and bowstring.

In order to prevent the above situation from happening, crossbows have successively added trigger anti-missing devices to prevent the trigger from being accidentally pressed when the upper string is not on the arrow body, resulting in better safety in use. However, when the string is to be put back , the trigger anti-aircraft device will form an obstacle, so that the string cannot be easily put back, causing inconvenience in use.

In view of the fact that the trigger anti-aircraft device cannot simply put the string back after winding the string, the creator of this creation is based on Naisi and the idea of creation. After many discussions, trial sample tests, and many revisions and improvements, he launched this creation. .

This invention provides a trigger reset device, which includes: a trigger base, an arrow slot channel extending backward from the middle of the front end, a wire catcher is pivotally arranged inside the trigger base, and the trigger base is installed on the rear side of the arrow slot channel. A displaceable safety switch is provided, and the displacement of the safety switch can be switched between an open position and a closed position. A connecting rod trigger is pivotally arranged near the bottom of the trigger base, and one end of the connecting rod trigger controls the thread catcher. The other end is provided with a linkage part, and the trigger base is provided with a linkage part accommodation groove and a brake switch pivot groove near the rear end, the linkage part accommodation groove communicates with the brake switch pivot groove, and the linkage part accommodates A lifting means is further provided in the groove; a linking piece is installed in the linking piece accommodating groove of the trigger base by sliding up and down. The linkage part of the linkage is engaged and interlocked. The upper end of the linkage is provided with a controlled unit; a button is combined with the controlled unit of the linkage and is linked with the lifting means. By pressing the button and matching the lifting means, the linkage can be driven to the Up displacement, when the button is released, the linkage member will move down and return to the original position; and a brake switch, pivotally arranged in the brake switch pivot groove of the trigger base, one end of the brake switch is provided with a stopper, the brake switch There is a brake switch spring between the trigger seat, and the brake switch spring bounces against the brake switch, so that the linkage is normally limited by the stopper of the brake switch, so that the linkage cannot be driven by the button Displacement; so that when the safety switch is in the closed position, press the brake switch, so that the linkage will no longer be limited by the stopper of the brake switch, and then press the button, and the button will drive the The linking piece produces an upward displacement, and then the linking piece drives the trigger of the connecting rod to break away from the hook.

The main purpose of creating the trigger reset device is that when the upper string is not on the arrow body, when the safety switch is kept in the closed position, the button cooperates with the linkage to drive the connecting rod trigger to disengage from the hook, so that the string can be easily removed. Put it back to complete the reset, and the convenience of use is improved.
