The slider 220 is connected to the nail magazine body 210. Blocks 230 are provided on both sides of the slider 220. The slider 220 is slidably connected to the fixed cylinder 120. The block 230 is engaged with the fixed cylinder 120. The pressing assembly 240 is provided in the fixed cylinder 120.

[0034] In the specific setting, the pressing assembly 240 includes a sliding rod 241, a pressure block 242 and a spring 243. The sliding rod 241 is slidably connected to the fixed cylinder 120, the pressure block 242 is connected to the sliding rod 241, and the two ends of the spring 243 are respectively connected to the pressure block 242 and the fixed cylinder 120, and the pressure block 242 corresponds to the card block 230. The setting of the sliding rod 241, the pressure block 242 and the spring 243 facilitates the pressing of the card block 230, thereby facilitating the disassembly, assembly and replacement of the nail magazine body 210.

[0035] In a specific configuration, a fixing block is provided at one end of the slide bar 241 , wherein the fixing block is provided at one end of the slide bar 241 , which makes it convenient for the user to press.

[0036] In a specific configuration, a first sliding groove is provided on the inner wall of the fixing cylinder 120 , and the pressing block 242 is slidably connected to the first sliding groove. The sliding connection between the pressing block 242 and the first sliding groove can facilitate the movement of the pressing block 242 to be limited.

[0037] In a specific configuration, a second sliding groove is provided on the inner wall of the fixing cylinder 120 , and the slider 220 is slidably connected to the second sliding groove. The sliding connection between the slider 220 and the second sliding groove can facilitate the movement of the slider 220 .
