[0033] Specifically, before use, the operator installs the nail to be fired at the nail placing position, then holds the handle 13 and the trigger 31 by hand, aims the muzzle 111 of the extended barrel 11 at the position to be fixed through the extended barrel 11, and then slowly pulls the trigger 31, at this time the trigger 31 drives the transmission member 32 to push the firing member 21 backward to compress the firing spring 22. When the trigger 31 is pulled to a certain angle, the transmission member 32 disengages from the firing member 21, at this time, continued force will trigger the firing. After the trigger 31 exceeds the critical position, the firing spring 22 releases energy instantaneously to push the firing member 21 to move forward at high speed, the firing part 211 impacts the tail of the nail to shoot the nail into the target, and after the firing is completed, the reset assembly drives the trigger 31 to return to the initial position, and the transmission member 32 cooperates with the firing member 21 again at this time, and the firing spring 22 is in a relaxed state, and the trigger can be reused again after re-storing force.
[0034] The utility model discloses technical scheme through setting up firing unit and force storage unit in the gun body 10, wherein the gun body 10 includes lengthened barrel 11, machine case 12 and handle 13, the lengthened barrel 11 is arranged at the front end of machine case 12, and the internal rifle bore is communicated with machine case 12, and the front end muzzle 111 is equipped with the nail position, and the nail of being launched is convenient for placing, and the lengthened barrel 11 design can extend the distance of driving nail, when the position needing fixed is higher or is located at the edge position of the risk of falling, the user can aim at the position needing fixed through the lengthened barrel 11 with the muzzle 111, and can directly drive nail and fix, avoid the user needing to help to climb and set up to be able to fix the position of higher part, and simultaneously avoid the user falling risk when driving nail and fixing.
[0035] When the position needing fixed is located in the narrow space, the user can drive nail and fix in the narrow space through the lengthened barrel 11, and aim at the position needing fixed with the muzzle 111, which solves the problem of difficult driving nail in the narrow space.
[0036] In addition, the firing unit includes firing member 21 and firing spring 22, the firing part 211, the matching part 212 and the extension part 213 of the firing member 21 cooperate and operate, and are flexibly movable in the rifle bore and the machine case 12 along the extension direction of the rifle bore, the firing part 211 is located at the nail position, when the firing spring 22 is released, the firing member 21 is pushed, the firing part 211 impacts the nail located at the nail position, and firing is realized. The force storage unit is composed of trigger 31, transmission member 32 and reset assembly, the trigger 31 is rotatably installed on the gun body 10, has an initial position and a force storage stroke of rotating towards the handle 13, when moving in the force storage stroke, the transmission member 32 is connected between the trigger 31 and the matching part 212 of the firing member 21, the transmission member 32 is driven to move, and then the matching part 212 compresses the firing spring 22, when the trigger 31 exceeds the critical position of the force storage stroke, the trigger 31 drives the transmission member 32 to be spaced apart from the firing member 21, the firing spring 22 releases energy instantaneously, the firing action is completed, and the reset assembly quickly drives the trigger 31 to return to the initial position after firing, so as to prepare for the next firing, the force storage and firing process are smooth and efficient, and the use convenience and operation efficiency of the nail gun are greatly improved.
[0037] In some embodiments, the gun body 10 is provided with a mounting hole, the mounting hole penetrates the gun body 10 along the movement direction of the firing member 21, the nail gun includes an adjusting knob 41, the adjusting knob 41 includes a screw rod part 412 and adjusting parts 411 and control parts 413 located at both ends of the screw rod part 412 respectively, the adjusting knob 41 is screw-connected and installed in the mounting hole through the screw rod part 412, the adjusting part 411 is located in the interior of the gun body 10, and one end of the firing spring 22, away from the matching part 212, is abutted on the adjusting part 411.
[0038] Specifically, by rotating the adjusting knob 41, the screwing position of the screw rod part 412 in the mounting hole changes, which drives the internal adjusting part 411 to move forward and backward, thereby directly changing the pre-compression amount of the firing spring 22. In this way, the user can adjust the firing force according to the nail specifications and operation requirements, avoiding the problem of over-firing or insufficient firing caused by the fixed force of the nail gun. Moreover, the control part 413 of the adjusting knob 41 is exposed on the gun body 10, so the user can complete the force adjustment by manually rotating without disassembling tools, and the adjustment process is intuitive and controllable, which is more convenient for the user to operate.
[0039] In some embodiments, the gun body 10 further comprises a nail magazine 14, which is provided with a nail slot communicating with the barrel, and the upper end of the nail slot communicates with a nail placement position. The nail gun further comprises a nail feeding unit, which comprises a guide column 141, an upper nail spring 142 and a nail feeding member 143. The guide column 141 is perpendicular to the barrel, and the nail feeding member 143 is slidingly installed on the guide column 141. The upper nail spring 142 is sleeved on the guide column 141 and abuts between the lower end of the nail slot and the nail feeding member 143. The upper nail spring 142 has elastic deformation to drive the nail feeding member 143 to move towards the nail placement position.
[0040] Specifically, a whole row of nails can be placed in the nail magazine 14, and a plurality of nails are pressed in the nail magazine 14 by the elastic deformation of the nail feeding member 143 driven by the upper nail spring 142. When the nail at the nail placement position is fired, the nail feeding member 143 will automatically push the nail for feeding, avoiding the need to manually feed the nail every time a nail is fired, which can significantly improve the operation efficiency, especially suitable for high-altitude operation or narrow space operation, reducing hand fatigue and reducing safety risks.
[0041] In some embodiments, the cross section of the barrel is rectangular, and the nail placement position is used to place a door nail. Specifically, the door nail fired by the nail gun is more suitable for fixing adjacent concrete formworks, and the rectangular cross section of the barrel perfectly matches the rectangular cross section of the nail rod, which can completely eliminate the possibility of nail rotation in the traditional circular barrel.
[0042] In some embodiments, the front side of the nail magazine 14 has an abutting surface perpendicular to the barrel, and the abutting surface and the muzzle 111 are located in the same plane. Specifically, by setting the abutting surface and the muzzle 111 in the same plane, a physical reference is provided for the positioning of the nail. When the abutting surface is tightly attached to the surface of the workpiece, the muzzle 111 automatically aligns with the target position, ensuring that the nail is vertically driven, especially suitable for door nail installation and other scenarios with high requirements for perpendicularity. Moreover, the abutting surface serves as an operating fulcrum, and the user only needs to lightly press the abutting surface against the workpiece to complete the positioning, without the need for additional holding force to maintain the stability of the gun body 10, providing a better operation experience for the user.
[0043] In some embodiments, the length of the barrel is not less than 50 cm. Specifically, when the nailing operation is performed in some dangerous locations, such as high places, edge locations with the risk of falling, near live areas, etc., the barrel longer than 50 cm allows the user to operate the nail gun at a relatively safe distance. The barrel not less than 50 cm can easily penetrate into a small space to perform nailing operation on components located in the small space. Further, during the nailing process, the impact of nails on the target object may generate flying debris, and the longer barrel allows the user to maintain a certain distance from the nailing point, reducing the possibility of injury caused by flying debris.
[0044] In some embodiments, the trigger 31 is provided with a mounting groove, a pin is arranged in the mounting groove, and a limiting protrusion 311 is arranged on the two inner walls of the mounting groove. The limiting protrusion 311 is located between the pin and the rotation shaft of the trigger 31. The transmission member 32 is rotatably mounted in the mounting groove through the pin. The upper end of the transmission member 32 is further provided with two pushing portions 321, which are respectively arranged on the two sides of the firing spring 22. The firing member 21 is provided with a matching groove 214 corresponding to the two pushing portions 321. When the trigger 31 moves in the charging stroke, the limiting protrusion 311 abuts against the transmission member 32 to prevent the transmission member 32 from rotating relative to the trigger 31. At the same time, the pushing portion 321 abuts against the groove wall of the matching groove 214 to drive the firing member 21 to compress the firing spring 22. When the trigger 31 moves to a critical position beyond the charging stroke, the pushing portion 321 moves to the outside of the matching groove 214 and no longer abuts against the matching groove 214.
[0045] Specifically, the transmission member 32 is rotatably mounted in the mounting groove of the trigger 31 through the pin. This mounting mode provides a stable support point for the transmission member 32, so that the transmission member 32 can stably rotate around the pin. At the same time, the two inner walls of the mounting groove are provided with limiting protrusions 311, which are located between the pin and the rotation shaft of the trigger 31. When the trigger 31 moves in the charging stroke, the limiting protrusion 311 abuts against the transmission member 32 to prevent the transmission member 32 from unnecessarily rotating relative to the trigger 31. This ensures the stability of the transmission member 32 during operation, reduces the risk of failure caused by the shaking or displacement of the transmission member 32, and improves the reliability of the overall structure of the nail gun. Moreover, during the charging process of the trigger 31, the pushing portion 321 abuts against the groove wall of the matching groove 214. This design makes the cooperation between the transmission member 32 and the firing member 21 more closely and stably, and the two pushing portions 321 can uniformly apply force, avoiding the deviation or jamming of the firing member 21 caused by uneven force, and ensuring that the firing spring 22 can be smoothly compressed.
[0046] In some embodiments, the reset assembly includes a first torsion spring 331 and a second torsion spring 332, the first torsion spring 331 is sleeved on the rotating shaft of the trigger 31 to drive the trigger 31 to move to the initial position, and the second torsion spring 332 is sleeved on the pin to drive the transmission member 32 to reset. During the process of driving the trigger 31 to move to the initial position after completing a nailing operation, the second torsion spring 332 drives the transmission member 32 to reset at the same time. When the transmission member 32 contacts the firing member 21, the transmission member 32 will avoid the firing member 21 by rotating until the trigger 31 and the transmission member 32 complete the reset.
[0047] Specifically, after completing a nailing operation, the first torsion spring 331 is sleeved on the rotating shaft of the trigger 31 to quickly drive the trigger 31 to return to the initial position, and the second torsion spring 332 is sleeved on the pin to quickly reset the transmission member 32. The automatic reset function of the double torsion springs enables the nail gun to quickly prepare for the next nailing operation without manual adjustment of the positions of the trigger 31 and the transmission member 32, greatly improving the efficiency of nailing operation, especially suitable for scenarios requiring continuous nailing. Moreover, during the reset process of the trigger 31, when the transmission member 32 contacts the firing member 21, the transmission member 32 will avoid the firing member 21 by rotating. This feature avoids mutual interference or collision between the transmission member 32 and the firing member 21 during the reset process, reduces the risk of component damage, and ensures the integrity and stability of the internal structure of the nail gun.
[0048] In some embodiments, the barrel is provided with a limiting assembly, which includes a metal limiting sheet 51 and a buffer pad 52. The metal limiting sheet 51 is arranged in the receiver 12 and located on the side of the fitting part 212 facing the muzzle 111. The buffer pad 52 is arranged on the side of the metal limiting sheet 51 facing the fitting part 212. When the trigger 31 is in the initial position, the fitting part 212 abuts against the buffer pad 52.
[0049] Specifically, the metal limiting sheet 51 is arranged in the receiver 12 and located on the side of the fitting part 212 facing the muzzle 111. It provides clear limiting for the movement of the firing member 21. When the trigger 31 is in the initial position, the fitting part 212 abuts against the buffer pad 52. The metal limiting sheet 51 can prevent the firing member 21 from moving forward excessively and avoid collision between the firing member 21 and other components of the gun body 10, thereby protecting the precise structure inside the gun body 10. When the fitting part 212 abuts against the buffer pad 52, the buffer pad 52 can play a buffering role. During the firing process of the nail gun, the firing member 21 will generate a large impact force. The buffer pad 52 can absorb and disperse this part of the impact force, reducing the direct impact on the metal limiting sheet 51 and the fitting part 212, and further reducing the risk of component damage.
[0050] In some embodiments, the extension 213 is in a sheet shape, and the front end of the extension 213 forms the firing part 211. Specifically, the sheet shape structure can effectively reduce the weight of the extension 213. During the firing process of the nail gun, the lighter extension 213 can reduce the influence of inertia, so that the firing part 21 can respond more quickly when the firing spring 22 releases energy, and the firing speed is improved. Faster firing speed means that the nail can obtain sufficient kinetic energy in a shorter time, so as to be more accurately and powerfully shot into the target object, and the effect and efficiency of nailing are improved.
[0051] The above merely describes the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields under the inventive concept of the present application is included in the patent protection scope of the present application.
