Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As shown in the figure, the present utility model discloses a punching device for a magazine slot cover of a nail gun, which includes an upper die fixing plate 1 and a lower die fixing plate 2. The upper template 3 is installed at the lower end of the upper die fixing plate 1. Guide posts 4 and elastic blocks 5 are installed at the four corners of the lower die fixing plate 2. Among them, a lower module one 6 is installed on two of the elastic blocks 5, and a lower module two 7 is installed on the other two elastic blocks. Elastic blocks 5 are installed on both sides of the upper ends of the lower module one 6 and the lower module two 7. The guide post 4 passes through two elastic blocks 5 at the upper and lower ends. The top of the guide post 4 passes through the upper template 3 and is installed on the upper die fixing plate 1. A punch pin one 8 and a punch pin two 9 are respectively installed at the lower end of the upper template 3. The lower module one 6 and the lower module two 7 are respectively provided with a hole one 10 and a hole two 11 corresponding to the punch pin one 8 and the punch pin two 9. Before punching, the product is first inserted from the lower module one 6 to the lower module two 7, and then the upper die fixing plate 1 is pressed down, driving the punch pin one 8 and the punch pin two 9 to move downward to realize punching of the product. When the upper die fixing plate 1 moves downward, it first contacts the elastic block 5, and the elastic block 5 is compressed. At this time, the punch pin one 8 and the punch pin two 9 realize punching. After the punching contact, the elastic block 5 resets, improving the reset efficiency. The present utility model uses the punch pin one 8 and the punch pin two 9 to punch the product synchronously, ensuring the consistency of the two holes.
