The implementation process of the invention comprises the following steps: in an initial state, the spring A is in a micro-pulling state, the clamping block is positioned in the clamping groove, and the spring K is in a compression state; the top end of the firing pin is positioned at the nail outlet, and the bottom end of the struck strip is positioned at the square through groove; the E-spring 66 pulls the E-weight away from the E-channel near the end of the nail to preserve the strike space.

When the construction is carried out in a wide space, as shown in fig. 19 (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 C-weight 33 via link 34 and E-spring 66 is extended. 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.

When the construction is carried out in a narrow space, as shown in fig. 19 (a), the U-shaped sleeve 2 is manually pulled to the end of the sliding groove 4 far away 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 shell 1 by using a medium force, the collision strip 19 instantaneously collides with the collided block 9, and the S spring 8 is compressed; before the striker 19 strikes the struck block 9, the large inclined angle inclined surface 60 of the fixture block 31 limits the B weight 32, so that the first rack 25 is difficult to drive the B weight 32 to cross the large inclined angle inclined surface 60 of the fixture block 31 through the a gear 27, the B gear 26 and the second rack 22; along with the gradual increase of the compression amount of the S spring 8, the thrust transmitted to the B weight 32 by the S spring 8 through the bearing block 44, the first rack 25, the A gear 27, the B gear 26 and the second rack 22 is gradually increased, and the B weight 32 extrudes the large inclined angle surface 60 of the fixture block 31 to enable the downward slow movement amplitude of the fixture block 31 to be larger and larger; when the compression amount is increased to a certain amount after the S spring 8 bears the impact, the B weight 32 just can cross the large inclined angle surface 60 of the fixture block 31, the fixture block 31 completely enters the K chute 50, and the K spring 63 is continuously compressed; at the moment of releasing the movement restriction of the clamping block 31 on the B-weight 32, the impacted striking strip 19 continues to push the impacted block 9 and under the dual action of the instant releasing restoring force of the S-spring 8, the impacted block 9 instantly pushes the B-weight 32 to rapidly impact the C-weight 33 through the S-spring 8, the bearing block, the first rack 25, the a-gear 27, the B-gear 26 and the second rack 22, the a-spring 29 is stretched, the C-weight 33 drives the E-weight 36 and the firing pin 37 to rapidly move towards the staple magazine 14 through the connecting rod 34, the E-spring 66 is stretched, and the firing pin 37 impacts one staple of the staple plate 72 to squeeze into a construction object.

After the striker 37 strikes a nail once, the nail is not necessarily completely pushed into the work; the rectangular sleeve 3 is reset manually, and in the period, under the reset action of the A spring 29, the second rack 22 pulls the B weight 32 to move and reset; in the process of resetting the B-weight 32, since there is less resistance to resetting the B-weight 32 by the small inclined surface 61 of the fixture block 31, the B-weight 32 is easy to extrude the fixture block 31 into the K-chute 50 again; when the a spring 29 returns to the initial slightly-pulled state, the return force of the a spring 29 is transmitted to stop when the positions of the latch groove 64 and the latch block 31 in the B weight 32 which moves and returns are opposite to each other, and the latch block 31 is reinserted into the latch groove 64 under the return action of the K spring 63. In the process of resetting the second rack 22, the second rack 22 drives the first rack 25 and the related structures on the first rack 25 to move and reset through the gear B26 and the gear A27; the S spring 8 can not be impacted by external force and can recover the original length. Under the reset action of the E spring 66, the E weight 36 and the firing pin 37 move and reset, and the E weight 36 drives the C weight 33 to move and reset through the connecting rod 34.

In order to ensure that the nail can be completely extruded into a construction material, the process that the striking strip strikes the struck block is repeated to enable the striking pin to strike the nail in a reciprocating mode until the nail is completely extruded into the construction material.

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; the S spring can store the impact energy and then instantly release the impact energy, so that the weight B obtains large impact force, the force of the impact pin impacting the nail shooting plate is ensured, and a good nail shooting effect is ensured as much as possible. The nail-shooting efficiency of the method is not the highest, but the nail-shooting device can completely fulfill the task which is difficult to be finished by the traditional nail-shooting gun in a narrow space, so that the use advantage of the nail-shooting device is better highlighted.

For the reason that the striking strip indirectly finishes the nail shooting action by striking the struck block, the force of striking the nail by the striking pin is possibly small, and the nail can smoothly enter a construction object by enabling the striking pin to strike the nail in a reciprocating manner through reciprocating operation. Through reasonable increase of the impact force, the elastic coefficient of the S spring, the large inclination angle of the clamping block and the weight of the rectangular sleeve, the impact force of the firing pin on the nail can be guaranteed to be always greater than the resistance force borne by the nail entering a conventional construction object (the nail cannot enter the conventional construction object) so as to guarantee the nail to smoothly enter the construction object.

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.
