The fishing gun device comprises a gun-shaped body, a fish hook, a fishing line, a trigger mechanism, a float mechanism, a sliding mechanism, a safety mechanism, a launching mechanism and a winding mechanism; the gun-shaped body has a containing cavity, the containing cavity is provided with a trajectory for guiding the float mechanism and the launching mechanism to move along a preset path; the fish hook is movably arranged in the float mechanism and connected with the winding mechanism through the fishing line; the sliding mechanism is slidably arranged on the gun-shaped body and is clamped with the launching mechanism to keep the launching mechanism in an energy storage state; the winding mechanism is used for winding and releasing the fishing line; the trigger mechanism is arranged below the winding mechanism and is clamped with the launching mechanism, triggers the winding mechanism to release the fishing line and simultaneously releases the locking of the launching mechanism, and then drives the float mechanism to be launched along the trajectory; the safety mechanism is used for preventing the launching mechanism from being misfired. The fish hook is automatically launched, the operation is simple and convenient, the safety is improved, and the fishing fun is enhanced.

The utility model belongs to the technical field of medical equipment, especially, relate to a kind of anastomat firing assembly.The utility model to the situation that cutting knife is located on the nail bin in prior art needs to ensure that nail bin is installed in place and nail bin is intact so that the advancing assembly of anastomat can correctly advance cutting knife to push slider to press and suture nail condition, provide a kind of anastomat firing assembly, it is unlocked by the cutting knife of correctly installed nail bin tail portion on the nail bin support above by being provided with the safety block with two safety unlocking areas, so that advancing assembly can smoothly push cutting knife, when advancing assembly is withdrawn, it can be unlocked safety block from the nail bin support below by advancing assembly to realize secondary unlocking, so that the stable firing and reply function are reached.
