The nail feeder 6 feeds the nail 9 into the nail tube 8 through the openings on the nail tube sleeve 4 and the nail tube 8 for firing, as shown in FIG. 3 . The upper end of the nail feeder 6 is provided with a boss, and the nail tube sleeve 4 and the nail tube 8 are respectively formed with notches corresponding to each other. When the nail is used up, the boss of the nail feeder 6 enters the notch on the nail tube 8 through the notch of the nail tube sleeve 4, as shown in FIG. 4 . At this time, the nail feeder 6 locks the nail tube 8 so that the nail tube 8 and the nail tube cover 4 cannot move relative to each other, and the nail shooting device cannot work. Only after the boss of the nail feeder 6 is pulled out from the notch on the nail tube 8, the nail shooting device can work. the

Pull out the boss of the nail feeder 6 from the notch on the nail tube 8 . At this moment, the nailer 9 can be loaded into the nailer 6 . Overcoming the effect of the spring (not shown) arranged between the centering sleeve 17 and the cylinder 2, the nail tube 8 is pushed toward the nail tube sleeve 4, and the nail tube 8 pushes the centering sleeve 71 so that the centering sleeve 71, the connecting rod The frame 5 and the outer shell 1 move together relative to the cylinder 2 away from the nail tube sleeve 4 .

When according to the nail shooting device of the present utility model, the standard type nail tube 81, NK or DN type nail tube 82, the special type nail tube 83 for electricians, and the special type nail tube 84 for gaskets shown in Fig. 6 need to be replaced, Forcefully pull out the nail tube 8 to overcome the pressing effect of the vertical annular retaining spring 43 on the steel ball 42, the nail tube 8 can be pulled out from the nail tube sleeve 4, and the nail tube 8 for other purposes can be directly inserted into the nail tube sleeve 4 In this way, the replacement of the nail tube 8 is completed, which is very convenient and quick. When it is necessary to get rid of the blockage of the nail 9 in the nail tube sleeve 4, the nail tube 8 is also pulled out. After the nail tube 8 is pulled out, the upper and lower directions of the nail tube sleeve 4 are continuous, and the blocked nail 9 can be easily removed from bottom to top, as shown in FIG. 5 . After the nail tube is reinstalled, the nail launching device can continue to be used. the

In order to facilitate the nail tube 8 to be inserted into the nail tube sleeve 4, the groove on the nail tube 8 is aligned with the penetration hole on the nail tube sleeve 4, and the nail 9 on the nail tube 8 enters the opening and the nail feeder 6. To align the direction of the nail 9, the cross section of the insertion section of the nail tube 8 to be inserted into the nail tube sleeve 4 may be rectangular, thereby preventing the nail tube 8 from rotating relative to the nail tube sleeve 4. That is, the cross-section of the insertion section of the nail tube 8 to be inserted into the nail tube sleeve 4 and the cross-section of the nail tube sleeve 4 can also be triangular, trapezoidal or other arbitrary polygons, or oval. the

Since the centering sleeve 7 is provided, even if the nail tube 8 has a full opening toward the nail tube sleeve 4 on the bottom side, the centering sleeve 7 can constrain the rod body 32 of the piston rod 3 to ensure that the piston rod 3 hits the nail 9 Concentric with nail pipe 8. By setting the combination of the front narrow and rear wide conical jumper 73 and the steel ball 72 on the centering sleeve main part 71, and making the inner wall of the jumper 73 have a tapered hole, the piston rod 3 moves toward the nail tube 8 to strike When the nail is shot 9, the steel ball 72 moves to the smaller end of the inner wall of the circlip 73 along with the piston rod 3, and the compression force generated by the circlip 73 forms the resistance to the forward movement of the piston rod 3, so that the piston rod 3 will not move toward the nail. The tube 8 moves freely, ensuring that the striking force of the piston rod 3 is not lost. When the piston rod 3 moved away from the nail tube 8 under the action of the pressure difference, that is, when the piston rod 3 reset, the steel ball 72 moved to the larger end of the inner wall diameter of the jump ring 73 along with the piston rod 3, and the compression force produced by the jump ring 73 The force fades away and the piston rod can be easily reset without resistance. the

In summary, because the front end of the nail tube cover 4 is provided with an upright annular retaining spring 43 and a fixed steel ball 42, it can accommodate and lock nail tubes 8 of different types and uses. During use, the nail tube 8 can be fixed inside the hollow tube body on the nail tube sleeve 4 by using the connecting rod frame 5, the centering sleeve 7 and the nail tube sleeve 4 connected to the outer shell 1, if the nail tube is replaced 8, it is only necessary to pull out the nail tube 8 from the hollow body, without disassembling or installing any parts in the nail shooting device, so that it is not necessary to disassemble or install the nail shooting device when replacing the nail tube purpose of screws or fittings in. Simultaneously, the connecting rod frame 5 and the centering sleeve 7 can also be used to prevent the phenomenon that the piston rod 3 is detached from the outside, which is beneficial to troubleshooting. the
