DETAILED DESCRIPTION

[0019] The utility model will be further described below in combination with the embodiments shown in the drawings:

[0020] As Figures 1 to 5 shown, the embodiment discloses a fast nail ejecting roll nail gun, which comprises a main body 1, the main body 1 is internally provided with a main cylinder 2, and the main cylinder 2 is internally provided with a piston body 3; the front end of the main body 1 is provided with a nail mechanism 4, the nail mechanism 4 comprises a pusher 41, the pusher 41 extends into the main cylinder 2 and is connected with the piston body 3; the outer side of the main body 1 is fixedly installed with an auxiliary cylinder 5, and the auxiliary cylinder 5 and the main cylinder 2 are provided with a first pipeline 6 connecting both; the main cylinder 2 is internally provided with a plurality of annularly distributed first air holes 7, and the first air holes 7 are communicated with the first pipeline 6; the main body 1 is also internally provided with a valve switch 8, and the valve switch 8 and the auxiliary cylinder 5 are provided with a second pipeline 9 connecting both.

[0021] The connecting sleeve 10 is sleeved on the outer layer of the main body cylinder 2 and abuts against the inner wall step of the main body 1. The connecting sleeve 10 is provided with a vent hole 11, and the vent hole 11 is connected with the first pipeline 6. The vent hole 11 is communicated with the first gas hole 7. The outer wall of the main body cylinder 2 is provided with a pair of annular protrusions 12, and the first gas hole 7 is arranged between the two annular protrusions 12. The connecting sleeve 10 is arranged on the annular protrusion 12. One of the annular protrusions 12 is provided with an annular blocking strip 13, and the connecting sleeve 10 is arranged on the annular blocking strip 13. The connecting sleeve 10 and each annular protrusion 12 are provided with a first sealing element 14, and the connecting sleeve 10 and the main body 1 are provided with a second sealing element 15. The main body cylinder 2 is divided into two gas chambers by the piston body 3. One of the gas chambers is arranged close to the nail ejection mechanism 4, and the other gas chamber is arranged close to the valve switch 8. The first gas hole 7 is arranged close to the gas chamber of the valve switch 8. The main body 1 is provided with a trigger 16 which is rotatably connected with the main body 1. The valve switch 8 is provided with a valve core 81, and the trigger 16 abuts against the valve core 81. When the trigger 16 is pulled, the valve core 81 moves relative to the valve switch 8. The valve switch 8 is communicated with the second pipeline 9 through the main body 1. The bottom of the main body 1 is provided with an air inlet 17, and the valve switch 8 is communicated with the air inlet 17. The main body cylinder 2 is provided with a plurality of annularly distributed second gas holes 18. The second gas holes 18 are arranged side by side and adjacent to the first gas hole 7.

When the valve core 81 is pushed to move by the trigger 16, the opening or closing state of the valve switch 8 can be controlled. When the valve switch 8 is opened, the gas in the main body 1 enters the valve switch 8, then enters the second pipeline 9 from the valve switch 8, then enters the auxiliary cylinder 5 along the second pipeline 9. The gas in the auxiliary cylinder 5 enters the connecting sleeve 10 through the first pipeline 6, then enters the inside of the main body cylinder 2 from the first gas hole 7, thereby pushing the piston body 3 to move axially. Similarly, the gas in the main body cylinder 2 enters the auxiliary cylinder 5 along the first pipeline 6, thereby realizing the function of charging and discharging. Because the first gas hole 7 is arranged close to the valve switch 8, the piston body 3 in the main body cylinder 2 can move a small stroke to charge and discharge the auxiliary cylinder 5, and the charging and discharging speed is faster. When the air pressure in the main body cylinder 2 is insufficient, the piston body 3 can still move normally by rapid charging and discharging, thereby driving the pusher 41 to extend and retract.
