As shown in FIG. 16, before the present invention is used, the nail ejection plate 72 is placed in the magazine slot of the magazine 14, in which state one end of the nail ejection plate 72 presses the push block 38, the push spring 67 is in a compressed state, and the other end is located at the nail outlet 70; during the nail ejection process, one end of the nail ejection plate 72 automatically fills the space in which the nail has been ejected, under the urging of the push spring 67.

The implementation process of the invention comprises the following steps: in the initial state, the spring B58 is in a slight-pulling state, the latch 31 is located in the slot 64, the spring K63 is in a compression state, and the spring a 29 is in a slight-pressing state; the X spring 43 is in a compressed state, and the B gear 26 is engaged with the second rack 22; the E spring 66 pulls the E-weight away from the E guide slot near the end of the nail to reserve the impact space, the top end of the striker 37 is located at the nail outlet 70, and the bottom end of the impacted strip 35 is located at the square through groove 10.

When the construction is carried out in a wide space, as shown in fig. 17 (b), the U-shaped sleeve 2 is manually pulled to the end of the sliding groove 4 close to the E guide rail 12, and the striker 19 is opposite to the struck strip 35; the top of the shell 1 is attached to a construction object, the rectangular sleeve 3 is rapidly moved towards the shell 1 manually with large force, the striking strip 19 instantly and strongly strikes the struck strip 35 through the square through groove 10, the E-weight 36 and the striking pin 37 move along with the struck strip 35, the striking pin 37 instantly and strongly strikes a nail of the nail ejecting plate 72 through the nail outlet 70, and the nail is struck into the construction object; during this time, E-weight 36 pulls D-weight 33 via link 34 and E-spring 66 is stretched. After a large impact, the rectangular sleeve 3 is manually reset, and the E-weight 36 and the striker 37 are moved and reset under the reset action of the E spring 66. The process of high-force impact is repeated for several times to ensure that the nail can completely enter a harder construction object. The above-described process of ejecting a nail is repeated.

When the construction is carried out in a narrow space, as shown in fig. 17 (a), the U-shaped sleeve 2 is manually pulled to the end of the sliding groove 4 far from the E guide rail 12, and the striking strip 19 is opposite to the struck block 9; the nail-shooting opening of the shell 1 extends into the narrow space and is attached to a construction object, and the rectangular sleeve 3 is positioned outside the narrow space; the rectangular sleeve 3 is rapidly moved towards the direction of the shell 1 by using a medium force, the striking strip 19 instantly strikes the struck block 9, the striking block drives the first rack 25 to move towards the direction of the shell 1 slowly due to the buffering of the S spring 8, the first rack 25 drives the second rack 22 to move towards the direction of the weight B30 through the gear A24, the one-way clutch A44, the rotating shaft A45, the gear C27 and the gear B26, and the spring A29 is compressed; meanwhile, the a one-way clutch 44 functions as a one-way drive, and the B one-way clutch 41 does not restrict the rotational direction of the B rotary shaft 40. The second rack 22 presses the B spring 58 via the B-weight 30, and the C-weight 32 hardly passes over the latch block 31 due to the large inclined surface 60 of the latch block 31 restraining the C-weight 32, and the B spring 58 is compressed. The lower pull-down rectangular sleeve 3 is moved and reset by the collision block 9 and the first rack 25 under the reset action of the S spring 8, and during the reset, the A gear 24 rotates reversely and the A rotating shaft 45 does not rotate reversely under the overrunning action of the A one-way clutch 44; the second rack 22 has a moving return tendency under the return action of the a spring 29, but the B one-way clutch 41 restricts the B rotating shaft 40 and the B gear 26 from reversely rotating, so that the second rack 22 does not have a return movement. Repeating the process that the striking strip 19 strikes the struck block 9, and the A spring 29 and the B spring 58 continue to be compressed; as the compression amount of the B spring 58 gradually increases, the C-weight 32 presses the large inclined surface 60 of the latch 31 to make the downward slow movement amplitude of the latch 31 gradually increase; when the compression amount of the B spring 58 reaches a certain amount, the C weight 32 just can cross the large inclined angle surface 60 of the clamping block 31 at the moment, the K spring 63 is continuously compressed, the C weight passes through the clamping block 31 and quickly impacts the D weight 33 under the instant release force of the B spring 58, the D weight 33 drives the E weight 36 and the firing pin 37 to quickly move towards the direction of the nail installing box 14 through the connecting rod 34, and the firing pin 37 strikes a nail of the nail shooting plate 72 and extrudes the nail into a construction object.

After the primary striker 37 strikes the nail-shooting plate 72, the nails are not necessarily completely extruded into the construction object; then the adjusting rod 23 is pulled to drive the adjusting plate 39 to move away from the second rack 22, the rotating shaft and the gear on the adjusting plate 39 move along with the adjusting plate 39, the X spring 43 continues to be compressed, the B gear 26 is disengaged from the second rack 22, and the second rack 22 moves to return to the initial position under the action of the a spring 29; during the process, the spring B58 returns to the original length, the second rack 22 pulls the C-weight 32 to move and reset through the weight B30 and the spring B58, and the C-weight 32 easily extrudes the clamping block 31 into the K sliding groove 50 due to the small resistance of the small inclined plane 61 of the clamping block 31; when the a spring 29 returns to the initial micro-pressure state, the return force of the a spring 29 is transmitted to stop when the position of the notch 64 of the C-weight 32, which moves to return, is opposite to the latch block 31, and the latch block 31 is reinserted into the notch 64 under the return action of the K spring 63. The external force of the adjusting rod 23 is removed, the B gear 26 is engaged with the second rack 22 again under the restoring action of the X spring 43, and then the process of striking the nail plate 72 by the firing pin 37 is repeated until the nails are completely pushed into the work.

The S spring can effectively relieve the instant impact force of the collision strip, so that the meshing between the first rack and the gear A cannot be subjected to overlarge impact force, and the purpose of protecting the gear is achieved; in addition, the spring B can store the energy of reciprocating impact, and the energy is released instantly after reaching a sufficient amount, so that the weight C obtains a large impact force, and finally, the sufficient force when the firing pin impacts the nail shooting plate is ensured, and the good nail shooting effect is ensured.

The nail-shooting box of the invention is mainly loaded with the nail-shooting plates with matched models so as to ensure the normal use of the nail-shooting gun.
