The nail shooter designed by the invention is suitable for the position with a coincident surface after the sealing part is folded.

The nail 6 designed by the invention is W-shaped, has certain hardness, and can meet the sealing strength requirement of the carton.

The specific working process is as follows: when the nail shooter designed by the invention is used, the limiting mechanism 42 limits the two sliding blocks 36 in the initial state.

When in use, the nails 6 are firstly put into the nail box 8 one by one, and the two ends of the nail 6 at the highest point are inserted into the two guide grooves 15 through the first spring 10 and the push plate 16; the magazine 8 is then clamped to the front side of the nailer 1 and the friction arc 22 engages the nail 6 at the highest point.

Then the motor 20 is controlled to work, the motor 20 drives the first gear 31 to rotate, the first gear 31 rotates to drive the second gear 32 to rotate, the second gear 32 rotates to drive the third gear 33 to rotate, the third gear 33 rotates to drive the fourth gear 34 to rotate, the fourth gear 34 rotates to drive the fifth gear 35 to rotate, and the fifth gear 35 rotates to drive the push rod 21 to slide in the shell 19; when the push rod 21 is forced to slide, because the sliding block 36 is limited, the push rod 21 drives the two friction arc plates 22 installed on the W-shaped head 30 to slide, in the sliding process, because the movable pulley 46 is in a static state, in the sliding process of the two friction arc plates 22 driven by the push rod 21, the two first pull ropes 47 are forced to be pulled, one end connected with the friction arc plates 22 pulls the two friction arc plates 22 to slide along the inner arc surface of the W-shaped head 30 to two sides under the matching action of the trapezoid guide block and the trapezoid guide groove, the two friction arc plates 22 slide to drive the nail 6 positioned at the topmost end of the nail box 8 and in contact fit with the two friction arc plates 22 through friction force, the two ends of the nail 6 slide towards the inner side of the carton under the action of the guide grooves 15 at two sides and bend, meanwhile, the two friction arc plates 22 slide to pull the two winding wheels 50 to rotate through the second pull rope 49, the two winding wheels 50 rotate to compress the four scroll springs 53 through the two mounting shafts 52, when the trigger plate 39 on the push rod 21 contacts with the trigger triangular block 43 in the sliding process of the push rod 21, the trigger plate 39 presses the trigger triangular block 43, so that the trigger triangle block 43 drives the corresponding slide bar 41 to slide, the slide bar 41 slides and drives the other slide bar 41 to slide through the sixth gear 37, namely, the two sliding rods 41 slide simultaneously, the sliding rods 41 pull the limit blocks 56, so that the limit blocks 56 in the two limit mechanisms 42 release the limit on the two sliding blocks 36, at this time, the two friction arc plates 22 are also pulled to the limit state, after the two sliding blocks 36 are released from limiting, the two first pull ropes 47 lose the pulling force on the two friction arc plates 22, at this time, the two friction arc plates 22 are reset under the action of the four volute springs 53, the two first pull ropes 47 and the two second pull ropes 49 are reset, the two sliding blocks 36 are matched with the two limiting plates 45, and the two limiting plates 45 limit the two sliding blocks 36; in the process of resetting the two friction arc plates 22, on one hand, the two ends of the nail 6 begin to bend, and on the other hand, the front end of the W-shaped head 30 has a limiting effect on the re-expansion of the nail 6, so that in the process of resetting the two friction arc plates 22, the nail 6 cannot be reset, and even if the nail 6 has a resetting tendency under the self-deformation force, the nail 6 is limited to be expanded by the front end of the W-shaped head 30; at this time, the push rod 21 is continuously pushed, the push rod 21 drives the two friction arc plates 22 arranged on the W-shaped head 30 to slide, in the sliding process, the limit plate 45 limits the sliding block 36, and the movable pulley 46 is in a static state, so that in the sliding process of the two friction arc plates 22 driven by the push rod 21, the two first pull ropes 47 are stressed and pulled, one end connected with the friction arc plates 22 pulls the two friction arc plates 22 to continuously slide towards two sides along the inner arc surface of the W-shaped head 30 under the matching action of the trapezoid guide block and the trapezoid guide groove, the two friction arc plates 22 slide to drive the nails 6 positioned at the topmost end of the nail box 8 and in contact fit with the two friction arc plates 22 through friction force, and the two ends of the nails continue to slide and bend towards the inner side of the carton under the action of the guide grooves 15 at the two sides; finally, nails 6 are nailed on the carton; the nailer is then disengaged from the nails 6 driven into the carton through the nail ejection slot 7.
