Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The push rod mechanism includes a push rod 12, a push rod 12 is sleeved on the outer side of a group of rotating rods 14, a fixing plate 11 is provided on one side of the inner side of the mounting shell 1, guide grooves are provided at both ends of the inner side of the fixing plate 11, and sliding rods matching with the guide grooves are provided on one side of both ends of the push rod 12 to guide the push rod 12 so that it can move in a specified direction, a multi-groove wheel 10 is sleeved on the middle part of the bottom of the mounting shell 1, and a hanging piece 2 matching with the multi-groove wheel 10 is provided in the middle part of the bottom of the push rod 12;

[0026] The lifting rod mechanism includes a V-shaped lifting rod 4, a V-shaped lifting rod 4 is sleeved on the outer side of a group of rotating rods 14, a mounting block is provided on one side of the bottom inner side of the mounting shell 1, and the bending part of the V-shaped lifting rod 4 is rotatably connected to the mounting block, so that the V-shaped lifting rod 4 can be limited so that it can be rotated, and one end of the inner side of the mounting shell 1 is provided with two groups of limiting plates 6, and two groups of through holes are opened on the top of one side of the two groups of limiting plates 6. The striker limiting rod 8 is sleeved on the inner side of the through hole for guiding the striker limiting rod 8 so that the striker limiting rod 8 can slide left and right to lock and unlock the striker plate 9, and a guide rail 7 is opened on the side away from the two groups of limiting plates 6, and the inner side of the two groups of guide rails 7 is slidably connected with a striker 15, and one end of the striker 15 is provided with a striker plate 9, and the inner side of the two groups of guide rails 7 is provided with a spring 13 connected to the striker 15;

[0027] The locking mechanism includes a movable rod 5, a movable rod 5 is sleeved on the outer side of a group of rotating rods 14, and a striker limit rod 8 is provided on one side of the movable rod 5 for sliding connection with two groups of limit plates 6. The inner sides of the V-shaped lifting rod 4, the movable rod 5 and the push rod 12 are all provided with movable grooves that cooperate with the rotating rod 14. When the driving wheel 3 rotates, the rotating rod 14 can move along the movable grooves on the V-shaped lifting rod 4, the movable rod 5 and the push rod 12.

[0028] Working principle: As the driving wheel 3 rotates, the device drives the push rod 12 to move in the direction away from the driving wheel. The hanging piece 2 at the bottom of the push rod 12 engages with the multi-groove wheel 10 to drive the multi-groove wheel 10 to rotate. When the multi-groove wheel 10 is pushed to the required angle, the lower semicircle of the multi-groove wheel 10 completes its operation and enters the upper semicircle. The hanging piece 2 of the push rod 12 stops contacting with the multi-groove wheel 10, and the push rod mechanism ends.

[0029] When the rotating rod 14 on the push rod 12 side enters the upper semicircle, the rotating rod 14 on the other side enters the lower semicircle, and the lifting rod mechanism moves toward the inner center of the outer shell due to the action of the pushing wheel 3.

[0030] The V-shaped lifting rod 4 pushes the firing pin 9 to the highest point in the first half of the stroke of the pushing wheel 3, but the locking mechanism takes effect at this stroke, and the firing pin limit rod 8 moves toward the groove wheel direction and contacts the firing pin 15, so that the firing pin 15 cannot move downward but is locked at the highest point by the locking mechanism. Since a spring 13 connected to the firing pin 15 is installed on the guide rail 7, the firing pin 15 is in the energy storage position at this time. As the pushing wheel 3 continues to rotate, the side of the V-shaped lifting rod 4 that contacts the firing pin 9 moves downward and separates from the firing pin 9. The pushing wheel 3 continues to rotate, and the firing pin limit rod 8 begins to be pushed away from the pushing wheel 3 until it stops contacting the firing pin 15. At this time, the firing pin 15 is released and moves downward until the needle tip pierces the ammunition primer. After the firing pin 9 contacts the V-shaped lifting rod 4, the firing pin 15 stops moving downward and is pushed upward by the V-shaped lifting rod 4 to the highest point, and a working cycle ends.
