The nail gun is capable of enabling different nail gauges to be self-adaptive, and is achieved through linkage of nail grooves, nail adjusting blocks, nail adjusting block springs, nail clamping groups, self-adaptive punching sheet guide rail groups, nail hanging plates and fasteners (nails) formed by the left casing and the right casing. The nails are placed into the nail grooves, the nail clamping group is pushed, the nail pushing block on the nail clamping group pushes the nails to the self-adapting punching sheet guide rail group, the nails are aligned to the different parts on the nail alignment block, the nail hanging plate and the nail touching self-adapting punching sheet guide rail group, so that the mechanism starts to perform self-adapting adjustment, the nails of different nail gauges accurately enter respective tracks and positions, so that the punching sheet group accurately strikes the nails, and the different nail gauges enter the respective tracks and positions and the actuation mode is as follows:

F nails fall on the channel of the guide rail group 1 and the nail clamp group A groove which are self-adaptive to the punching sheet, and the tail of the nail is hung on the nail clamp group, the nail hanging plate and the nail hanging groove of the right machine shell.

F, no head nails fall on the channel of the self-adaptive punching sheet guide rail group 1 and the nail clamp group A groove, and the nail feet stand on the nail clamp group bottom plate.

CT nails fall on the channel 2 of the self-adaptive punching sheet guide rail group, and are nailed to clamp the A groove and the B groove of the group.

T nails are arranged in the 3 channels of the self-adaptive punching sheet guide rail group, and are nailed to clamp the A groove and the C groove of the group.

TRA nails fall on the 4 channels of the self-adaptive punching guide rail group, and are nailed in the A groove and the C groove of the clamp group.

The nail blocking body on the nail blocking strip and the side surface of the nail outlet A of the guide nail on the punching guide rail seat form a second channel, and a CT3 type nail C, CT type nail can be contained in the second channel. The higher the nail blocking height of the nail blocking body to the nail foot is, the better the nail blocking stability is, and the nail foot cannot deflect. The nail blocking strip can be actuated by the punching sheet when any nail is punched.

In order to ensure that the punching sheet is always accurate in position and smooth in sliding in the guide groove formed by the self-adaptive punching sheet guide rail group and the peg plate, the manufacturing cost of the punching sheet group can be reduced, the punching sheet group consists of a punching sheet seat and the punching sheet, and the two parts are movably connected, so that the punching sheet is always guided by the guide groove formed by the self-adaptive punching sheet guide rail group and the peg plate, and is not influenced by other factors, then the punching sheet seat and the punching sheet are prevented from being longitudinally separated through the hanging lugs on the punching sheet, and the punching sheet seat and the punching sheet are prevented from being laterally separated through the two bosses on the punching sheet seat and the limiting guide ribs of the left and right machine shells.

The alignment block is arranged at the side end of the punching sheet guide rail group, the left casing is provided with a nail groove formed by the left casing and the right casing when the T-shaped nail is used, the nail clamp group nail pushing block is required to push the T-shaped nail into a third channel of the punching sheet guide rail group, the punching sheet guide rail group is provided with 4 channels, the size of the third channel is smaller than that of the fourth channel, then the T-shaped nail can move in a left-right manner after being arranged in the nail groove formed by the left casing and the right casing, the T-shaped nail can not be accurately pushed into the third channel of the punching sheet guide rail group by the nail clamp group nail pushing block, and the T-shaped nail can be accurately guided into the third channel of the punching sheet guide rail group by the guide angle on the alignment block. When the TRA type nail is used, the TRA type nail is placed in the nail groove formed by the left casing and the right casing, the nail clamp group nail pushing block pushes the TRA nail, the TRA type nail foot pushes the alignment block to shrink inwards, the TRA type nail smoothly enters the 4 channels of the punching guide rail group, and meanwhile the alignment block provides auxiliary thrust for the side surface of the TRA type nail, so that one side of the TRA type nail is well attached to the side surface of the nail A, which is led out of the punching guide rail group, and the nailing stability of the TRA type nail is improved. When the nails in the nailing gun are driven out, the nail clamp is pulled out, and the reset spring of the alignment block pushes the alignment block to reset.
