[0025] The utility model is now further described with reference to the accompanying drawings.

[0026] like Figures 1 to 9 As shown, a nail gun head adjustment device comprises a nail gun head 13, a starting sleeve 11, a nail tube 12, a retaining spring and a ball plunger 19. The nail gun head 13 is mounted on the gun seat 3, a nail hole 130 is arranged at the center of the nail gun head 13, and a connecting groove 139 is arranged below the nail gun head 13. The connecting groove 139 is used to install an automatic nail magazine 4, and the automatic nail magazine 4 is used to transport nails. The nail gun head 13 is also provided with a clamping groove 138 and a limiting hole 137 located at the bottom of the clamping groove 138. The limiting hole 137 is also connected to the nail hole 130. The retaining spring is movably inserted in the clamping groove 138, and the retaining spring part enters the nail hole 130 through the limiting hole 137. The starting sleeve 11 is slidably inserted in the nail hole 130. A plurality of positioning grooves 111 are arranged in an annular array on the outer circumferential surface of the starting sleeve 11, and the positioning grooves 111 are arranged along the axial direction to form a long strip groove. The end of the starting sleeve 11 is provided with an internal thread, and the end of the nail tube 12 is provided with an external thread. The starting sleeve 11 is connected to the nail tube 12 through the thread. When the starting sleeve 11 is rotated, the length of the starting sleeve 11 extending out of the gun head 13 can be adjusted. The nail tube 12 is movably inserted into the nail hole 130. The two sides of the nail tube 12 are symmetrically provided with anti-slip grooves 121 and anti-slip blocks 122. The retaining spring is movably inserted into the anti-slip groove 121 and is arranged opposite to the anti-slip block 122. The anti-slip groove 121 facilitates the forward and backward movement of the nail tube 12 along the axial direction, and can cooperate with the retaining spring to prevent the nail tube 12 from rotating freely. The anti-slip block 122 is arranged opposite to the retaining spring to prevent the nail tube 12 from escaping from the nail hole 130. The ball plunger 19 is installed on the gun head 13 and is located at one end of the nail hole 130. The ball plunger 19 is arranged opposite to the positioning groove 111 and is used to be inserted into the positioning groove 111 to prevent the starting sleeve 11 from rotating freely.

[0027] The nail tube 12 is provided with a nail feeding hole 120 and a nail feeding groove 123. The nail feeding groove 123 is located at the bottom of one end of the nail tube 12 and communicates with the connecting groove 139 for feeding nails.

[0028] In order to facilitate the installation of the ball plunger 19 , a connecting seat 133 is provided on the gun head 13 . A positioning through hole 136 is provided on the connecting seat 133 . The positioning through hole 136 is communicated with the nail hole 130 , and the ball plunger 19 is installed in the positioning through hole 136 .

[0029] When in use, the starting sleeve 11 is rotated as needed, and the starting sleeve 11 is adjusted in length to be extended or retracted through a thread, while the ball plunger 19 is inserted into the positioning groove 111 , and the ball plunger 19 prevents the starting sleeve 11 from rotating freely through the positioning groove 111 .

[0030] The reset of the start sleeve 11 is realized by a protective device, which includes a protective seat 21, a protective rod 22, a protective spring 25 and a micro switch. The gun head 13 is provided with a nail hole 130, a push groove 131 and a protective installation groove 132. The protective installation groove 132 is located above the tail of the gun head 13, and the push groove 131 is communicated with the nail hole 130 and the protective installation groove 132 respectively. Two guide shafts 24 are symmetrically installed in the protective installation groove 132, and a sliding hole 212 is provided on the protective seat 21. The sliding hole 212 of the protective seat 21 is slidably inserted on the guide shaft 24. The two guide shafts 24 improve the stability and reliability of the sliding of the protective seat 21. A push rod 211 is provided at one end of the protective seat 21, and a protective rod 22 is provided at the other end. The protective rod 22 is arranged opposite to the micro switch, and the micro switch is installed in the switch groove 31 of the gun seat 3. The protective seat 21 is located in the protective installation groove 132, and the push rod 211 is movably inserted in the push groove 131. The protection spring 25 is movably inserted on the guide shaft 24, and the two ends thereof are respectively against the side surfaces of the protection seat 21 and the pushing groove 131. The starting sleeve 11 is connected to the nail tube 12, and both are movably inserted in the nail hole 130. The starting sleeve 11 is also located outside the gun head 13, and the nail tube 12 is located on one side of the pushing groove 131, and the end thereof is against the end surface of the pushing rod 211. The protection spring 25 pushes the starting sleeve 11 outward through the pushing rod 211, so that the protection rod 22 is away from the micro switch. When nail shooting is required, the starting sleeve 11 is pushed against the position where nail shooting is required, and then the nail gun is pushed forward. The starting sleeve 11 pushes the pushing rod 211 through the nail tube 12, and the pushing rod 211 compresses the protection spring 25, and the protection seat 21 drives the protection rod 22 to move toward the direction of the micro switch. When the protection rod 22 is against the micro switch and is turned on, the switch corresponding to the trigger of the nail gun can be started, and then nail shooting is performed.

[0031] In the free state, the protection spring 25 pushes the starting sleeve 11 out of the shooting gun head 13 to a set length through the pushing rod 211.

[0032] When the starting sleeve 11 does not rest on the object to be set, the nail gun cannot work normally and cannot shoot nails, thereby improving safety and avoiding accidents.

[0033] In order to reduce friction and improve the smoothness of sliding of the protection seat 21 , a sliding sleeve is further installed on the sliding hole 212 . The sliding sleeve can be a plastic sleeve or a self-lubricating sleeve. The sliding sleeve is slidably inserted on the guide shaft 24 .

[0034] An insulating elastic column 23 is mounted at the end of the protection rod 22. The insulating elastic column 23 is arranged opposite to the micro switch, which can reduce the impact force on the micro switch and achieve insulation, thereby improving the overall reliability and stability.

[0035] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the claims of the present invention.
