[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model installs a protective cover on the outside of the lifting column and the punch. The protective cover is slidably connected to the lifting column, and a first spring is used to support the extension block on the protective cover. When the button machine is working, since the bottom surface of the protective cover is lower than the punch, the protective cover will preferentially contact the base, causing pressure on the pressure sensor during contact, indicating that the protective cover covers the button table. At this time, the button machine body can enter the working state. Under the elastic pressure of the first spring, the protective cover is tightly attached to the base to ensure the stability of the protective work. If the pressure sensor does not transmit a pressure signal, it means that the protective cover has not formed a protective state, so the button machine body cannot be opened, thereby ensuring the priority of the protective work.

[0017] 2. The utility model provides positioning blocks on both sides of the protective cover. Under normal circumstances, the positioning blocks are located on the outside of the protective cover. When the punch needs to be replaced and maintained, in order to avoid the protective cover blocking the punch and increasing the difficulty of maintenance, the user can pull the protective cover upwards before maintenance until the positioning block is flush with the positioning slot. At this time, the staff pushes the positioning block to extend its inner end into the inside of the positioning slot, thereby fixing the protective cover at this position. At this time, the punch is exposed to the external environment, and the staff can easily replace and maintain the punch.

[0018] 3. The utility model provides feed ports on both sides of the protective cover. When placing materials, the adjusting column is pulled first to drive the pressure plate to move upward to keep the feed port open. At this time, the staff can place the materials in the nailing position. After loosening the adjusting column, the pressure plate is brought into close contact with one side of the material under the reset of the second spring to fix the material, thereby improving the stability of the material nailing process.
