Patent name: Manufacturing method of pneumatic nail gun
Technical field:
The utility model relates to a pneumatic tool, in particular to a pneumatic nail gun .
The so-called pneumatic nail gun is a gun-type nailing tool that uses an air source to nail. Existing pneumatic nail guns use straight nails as F-type pneumatic nail guns, or use T-shaped head straight nails as T-type pneumatic nail guns (both commonly known as straight nail guns), and those that use H-shaped nails are J-type pneumatic nail guns ( Commonly known as code nail guns), those that use straight nails without nail heads are P-type pneumatic nail guns (commonly known as mosquito nail guns), and those that use square nail-head straight nails are ST-type pneumatic nail guns (commonly known as steel nail guns). Their structures Roughly the same, including the shell, cylinder and cylinder head, piston, magazine, gun head, firing pin, balance valve, trigger, valve stem, gas nozzle, etc. The working principle is also the same. When the compressed gas is introduced into the gun body from the gas nozzle, the button Turn the trigger. At this time, the pressure at the rear of the balance valve is less than the pressure at the front of the balance valve. The balance valve opens, and the compressed gas quickly enters the cylinder, pushing the piston to drive the firing pin to hit the tail of the nail in the magazine, causing the nail to be ejected. The difference is The main reason is that the stapled magazine and firing pin have different shapes. However, these current pneumatic nail guns have the same shortcomings in three main aspects. First, they are unsafe. As long as there are nails in the magazine, the nails will be fired when the trigger is pulled in any direction. Therefore, each manufacturer has a label on the packaging (box). There are words such as "Do not aim at people" or "Do not aim at people"; secondly, it can only be fired in a single shot, that is, pull the trigger to shoot one nail at a time, which is low work efficiency; thirdly, the exhaust hole is fixed. Operating in the exhaust direction can easily hurt people's eyes. No pictures, sorry.
