[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This design uses a lever to move the barrel connector back and forth via a transmission rod, first limit shaft, and second limit shaft. The barrel connector moves along the surface of the depth adjustment plate via auxiliary adjusting teeth, which in turn causes the depth adjustment plate to move up and down repeatedly via the main adjusting teeth. A strong spring then resets the depth adjustment plate, thus completing the barrel depth adjustment. The main adjusting teeth, auxiliary adjusting teeth, first limit block, sliding column, and guide rod limit the barrel connector, preventing displacement of the adjusted depth due to vibration during nailing and improving the stability of the mechanism. To restore the depth to its initial position, simply pull the lever, moving the depth adjustment plate downwards. The barrel connector returns to its initial position under the action of the reset spring. Releasing the lever resets the depth adjustment plate, again fixing the barrel connector. This depth adjustment mechanism is simple in structure, easy to operate, and provides convenience for operators. Attached Figure Description

The barrel connecting seat 2 is limited by the main adjusting tooth 15, the auxiliary adjusting tooth 21, the first limiting block 11, the sliding column 24, and the guide rod 31 to prevent the depth adjustment from shifting due to vibration during nailing, thus improving the stability of the mechanism.
[0027] The working principle of this utility model is as follows: According to the nailing depth, the operator moves the lever 43 to move the barrel connecting seat 2 along the surface of the depth adjustment plate 14. After the depth is adjusted, the barrel connecting seat 2 is limited and fixed by the main adjustment tooth 15 and the auxiliary adjustment tooth 21, thereby fixing the barrel 22 and completing the process of adjusting the depth of the barrel 22. When it is necessary to restore the adjusted depth to the initial position, simply pull the lever 13 to move the depth adjustment plate 14 downward. At this time, the barrel connecting seat 2 returns to the initial position under the action of the return spring 27. Release the lever 13, the depth adjustment plate 14 resets, and the barrel connecting seat 2 is limited and fixed again.
