Description

Technical Field

[0001] The present invention relates to the technical field of nail guns, and particularly to a nozzle device and a nail gun. Background Art

[0002] In many fields such as construction, decoration, and woodworking manufacturing, nail guns, as an efficient and convenient fastening tool, have been widely used. It can quickly drive nails into the base material to achieve a firm connection between various components, greatly improving work efficiency and reducing labor intensity.

[0003] Conventional nail guns usually have a curved rod movably arranged on the nozzle. This curved rod serves as a safety mechanism. During the operation of the nail gun, the front end of the curved rod needs to be positioned on the processing surface. Only when the curved rod is in correct contact with the processing surface and reaches a certain pressure or position state, the safety switch of the nail gun will be unlocked to allow the firing operation. This design is intended to prevent the nail gun from accidentally firing when not correctly aligned with the target surface, thus ensuring the safety of the operator.

[0004] However, this conventional structure gradually reveals a significant problem during actual use. Since the front end of the curved rod is designed to be relatively large to ensure that it can be stably positioned on the processing surface and provide a reliable safety function. But at the same time, the nail is at the center position of the curved rod. This structural layout leads to a serious defect: the operator cannot accurately position the shooting position of the nail through the curved rod.

[0005] In actual application scenarios, especially when fixing a perforated iron plate, it is necessary to accurately fix the perforated iron plate at a specific position, which requires the nail to precisely pass through the hole position on the iron plate. However, due to the relatively large front end of the curved rod and the nail being at its center, it is very difficult for the operator to visually and accurately judge the relative position between the nail and the hole position when positioning the front end of the curved rod on the iron plate surface. Once the operator fires without aligning the nail with the hole position, the nail will directly hit the iron plate. Due to the huge impact force generated when the nail gun fires, after the nail hits the iron plate at high speed, it is very likely to bounce off, posing a risk of scratching, stabbing or even more serious physical injuries to the operator or other people around. At the same time, it may also hit the surrounding frame structure or other equipment, resulting in damage to the frame structure and equipment failure. Summary of the Invention

[0006] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a nozzle device and a nail gun, which can solve the problem that the nail to be fired cannot be aligned with the target hole to be penetrated due to the setting of the curved rod assembly.

[0007] The technical solution adopted by the present invention to solve its problems is:

[0008] A nozzle device, comprising:

[0009] A nozzle seat, provided with a sliding groove thereon;

[0010] A nozzle, having a nail driving channel, and the nozzle is slidably arranged in the sliding groove;

[0011] A safety signal trigger switch, which includes a first trigger member and a second trigger member. The first trigger member is arranged on the nozzle, and the second trigger member is arranged in the direction of the nozzle towards the nozzle seat, and the second trigger member can move synchronously with the nozzle seat. When the nozzle seat and the nozzle move relative to each other, the second trigger member moves towards the first trigger member, so that the first trigger member and the second trigger member trigger a safety release signal;

[0012] A reset member, connected to the nozzle, so that after the nozzle and the nozzle seat move relative to each other, the nozzle is reset under the action of the reset member.

[0013] Further, the first trigger member is a magnet, and the second trigger member is a Hall element;

[0014] Or, the first trigger member is a contact block, and the second trigger member is a micro switch.

[0015] Further, it further includes a gun clip, which has a nail row channel, and the nail row channel is communicated with the nail driving channel.

[0016] Further, it further includes an anti-backward component, and the anti-backward component includes:

[0017] A nail blocking strip, which includes a connecting part and a limiting part connected in sequence. The connecting part is connected to the nozzle, and the limiting part extends into the nail driving channel;

[0018] A nail blocking strip reset member, which abuts against the connecting part;

[0019] Wherein, the limiting part moves towards the outside of the nail driving channel under the push of the nail in the nail row channel, and the connecting part simultaneously compresses the nail blocking strip reset member. When the nail passes over the limiting part and enters the nail driving channel, the nail blocking strip reset member pushes the connecting part and the limiting part to reset.

[0020] Further, it further includes an anti-backward component, and the anti-backward component includes:

[0021] A nail blocking strip, which includes a connecting part and a limiting part connected in sequence. The connecting part is rotatably connected to the nozzle, and the limiting part extends into the nail driving channel;

[0022] The nail stop strip reset member, the nail stop strip reset member abuts against the connecting portion;

[0023] Wherein, when the nail pushing block of the gun clip pushes the nail towards the nail feeding channel, the connecting portion drives the limiting portion to rotate synchronously, and the connecting portion simultaneously compresses the nail stop strip reset member. When the nail passes over the limiting portion and enters the nail feeding channel, the nail stop strip reset member pushes the connecting portion and the limiting portion to reset;

[0024] When the nail in the nail feeding channel moves towards the limiting portion, the connecting portion or the limiting portion abuts against the nozzle to limit the nail in the nail feeding channel from moving towards the nail row channel.

[0025] Furthermore, one side of the limiting portion facing the nail row channel is a guiding surface, and the guiding surface is inclined towards the nail feeding channel from the side close to the connecting portion to the side far from the connecting portion.

[0026] Furthermore, the nail feeding channel is provided with a limiting step, and the limiting step abuts against at least the tail of one of the nails in the nail feeding channel.

[0027] Furthermore, the nozzle seat is provided with a limiting guiding pin, the nozzle is provided with a limiting guiding groove, and one end of the limiting guiding pin extends into the limiting guiding groove.

[0028] Furthermore, the nozzle seat is provided with a first sliding mating portion, and the nozzle is provided with a second sliding mating portion that slidably mates with the first sliding mating portion.

[0029] A nail gun, comprising:

[0030] A housing;

[0032] A trigger assembly;

[0033] The above-mentioned nozzle device;

[0034] Wherein, the power device and the trigger assembly are both assembled on the housing, the nozzle seat is fixedly connected to the power supply device, and the first trigger member and / or the second trigger member are electrically connected to the trigger assembly.

[0035] Furthermore, it further includes a guiding assembly, one end of the guiding assembly is connected to the housing, and the other end is connected to the gun clip, so that the housing can slide relative to the gun clip.

[0036] In summary, a nozzle device and a nail gun provided by the present invention have the following technical effects:

[0037] 1. The nozzle is connected to the nozzle seat by a sliding connection. Through the relative movement between the nozzle and the nozzle seat, the first trigger and the second trigger are driven to trigger the safety release signal according to the change in the relative position between the nozzle and the nozzle seat. The above structure replaces the traditional curved lever assembly, ensuring the safety of the nail gun using this nozzle device.

[0038] 2. The structure of the nozzle and nozzle seat with a sliding connection replaces the curved lever assembly, enabling the nozzle to directly contact the working surface, greatly shortening the distance from the nail to be fired to the target point, thus eliminating the interference of the front end of the curved lever on positioning. The operator can directly judge the relative position between the nail and the hole, thereby greatly improving the accuracy of the nail shooting and avoiding the risk of misfired nails caused by positioning deviation.

Detailed implementation manners

[0050] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all examples. All other examples obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the protection scope of the present invention.

[0051] For the convenience of understanding the embodiments of the present invention, the following will take specific embodiments as examples to further explain in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0052] In the description of the present invention, it should be noted that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0054] Refer to Figures 1 - 10, the present invention discloses a nozzle device, which includes a nozzle seat 1, a nozzle 2, a safety signal trigger switch, and a reset member 4. The nozzle 2 has a nail feeding channel 21. The nozzle 2 is slidably connected to the nozzle seat 1. The safety signal trigger switch includes a first trigger member 31 and a second trigger member 32. The first trigger member 31 is provided on the nozzle 2. The second trigger member 32 is provided in the direction of the nozzle 2 towards the nozzle seat 1, and the second trigger member 32 can move synchronously with the nozzle seat 1. When the nozzle seat 1 slides towards the nozzle 2, the second trigger member 32 moves towards the first trigger member 31, so that the first trigger member 31 and the second trigger member 32 trigger a safety release signal. The reset member 4 is connected to the nozzle 2, so that after the nozzle 2 moves towards the nozzle seat 1, the nozzle 2 is reset under the action of the reset member 4.

[0055] Refer to Figures 1 - 4 As shown, specifically, the nozzle seat 1 is slidably connected to the nozzle 2, and the two can slide relative to each other. The nozzle 2 has a nail feeding channel 21 to facilitate the firing after the nail 7 is filled. The safety signal trigger switch includes a first trigger member 31 and a second trigger member 32. The first trigger member 31 is provided on the nozzle 2 and moves synchronously with the nozzle 2. The second trigger member 32 is provided in the direction of the nozzle 2 towards the nozzle seat 1, and the second trigger member 32 can move synchronously with the nozzle seat 1. The second trigger member 32 can be specifically provided on the nozzle seat 1 or the housing 81 of the nail gun to realize the movement of the nozzle seat 1 towards the nozzle 2. When the nozzle seat 1 moves towards the nozzle 2, the second trigger member 32 moves synchronously towards the nozzle 2, that is, towards the first trigger member 31. When the first trigger member 31 and the second trigger member 32 are close to or in contact with each other, the safety release signal is triggered. After the nozzle 2 completes the sliding, the reset member 4 pushes the nozzle 2 to reset and return to the initial position. The reset member 4 can be a spring or an elastic sheet, with one end fixed to the nozzle seat 1 or the housing 81 and the other end acting on the nozzle 2.

[0056] The working principle of the above structure:

[0057] Align the nozzle 2 with the target point, and then push the nozzle seat 1 and the second trigger member 32 towards the target point. When the first trigger member 31 and the second trigger member 32 can trigger the safety release signal, pull the trigger to complete the normal firing. After the firing is completed, the reset member 4 pushes the nozzle 2 to complete the reset.

[0058] It should be noted that if the first trigger member 31 and the second trigger member 32 are contact trigger switches, the nozzle seat 1 can move to make the second trigger member 32 contact the first trigger member 31; if the first trigger member 31 and the second trigger member 32 are non-contact trigger switches, the nozzle seat 1 can move to a state where the second trigger member 32 and the first trigger member 31 are non-contact to trigger the insurance release signal, which is not limited herein.

[0059] Refer to Figure 2 and Figure 5 As shown, in some embodiments, the nozzle seat 1 is provided with a chute 11, the nozzle 2 is slidably disposed in the chute 11, the nozzle seat 1 is provided with a limit guide pin 12, the nozzle 2 is provided with a limit guide groove 23, and one end of the limit guide pin 12 extends into the limit guide groove 23.

[0060] Specifically, the nozzle seat 1 is provided with a chute 11, and the nozzle 2 is slidably disposed in the chute 11, which can ensure the stability during the relative sliding of the nozzle 2 and the nozzle seat 1. The nozzle seat 1 is provided with a limit guide pin 12, the nozzle 2 is provided with a limit guide groove 23, and one end of the limit guide pin 12 extends into the limit guide groove 23. During the sliding of the nozzle 2 relative to the nozzle seat 1, the limit guide pin 12 slides synchronously in the limit guide groove 23 to provide a guiding function for the relative sliding of the nozzle 2 and the nozzle seat 1. The length of the limit guide groove 23 can be selected to be the same as the length of the relative movement of the nozzle 2 and the nozzle seat 1, so that when the nozzle 2 and the nozzle seat 1 are in a compressed state, the limit guide pin 12 abuts against the side wall of one end of the limit guide groove 23, thereby ensuring the stable triggering of the first trigger member 31 and the second trigger member 32 during the nail shooting process; when the nozzle 2 and the nozzle seat 1 are in the initial state, the limit guide pin 12 abuts against the side wall of the other end of the limit guide groove 23, thereby preventing the nozzle 2 from disengaging from the chute 11 of the nozzle seat 1.

[0061] Of course, the length of the limit guide groove 23 can also be greater than the length of the relative movement of the nozzle 2 and the nozzle seat 1, as long as it can prevent the nozzle 2 from disengaging from the nozzle seat 1, which is not limited herein.

[0062] Refer to Figure 2 and Figure 3 As shown, in some embodiments, one end of the nozzle 2 facing the nozzle seat 1 is provided with a first assembly pin 25, the nozzle seat 1 is provided with a second assembly pin 14 corresponding to the nozzle 2, the reset member 4 is a spring, one end of the spring is sleeved on the first assembly pin 25, and the other end is sleeved on the second assembly pin 14, which facilitates the assembly of the spring and can also maintain the stability of the spring during the repeated compression and release of the spring.

[0063] Refer to Figure 2 and Figure 4As shown, in some embodiments, the first trigger 31 is a magnet, and the second trigger 32 is a Hall element. When the nozzle seat 1 moves towards the nozzle 2, the Hall element moves synchronously with the nozzle seat 1. When the Hall element approaches the magnet, the magnet triggers an insurance release signal of the Hall element.

[0064] Specifically, the first trigger 31 is a magnet, and the second trigger 32 is a Hall element. The size of the magnet is designed according to actual requirements and can be selected as a small cylindrical shape or a rectangular block shape, which is convenient for the combined installation of the magnet and the nozzle 2. The second trigger 32 is a Hall element, which is installed on one side of the nozzle seat 1 facing the nozzle 2 and is aligned with the magnet along the sliding direction. When the magnet approaches the Hall element, an insurance release signal is triggered. By using the combination of the Hall element and the magnet, the Hall element has a small volume, and the occupied space is much smaller than that of the traditional mechanical contact structure, which is convenient for the miniaturization design of the nozzle device. Moreover, by using the cooperation mode of the Hall element and the magnet, mechanical wear can be reduced.

[0065] In other embodiments, the first trigger 31 is a contact block, and the second trigger 32 is a microswitch. When the nozzle seat 1 moves towards the nozzle 2, the contact of the microswitch contacts the contact block to trigger an insurance release signal.

[0066] Specifically, when the first trigger 31 is a contact block, the contact block can be integrally formed with the nozzle 2. The second trigger 32 is a microswitch, which is installed on one side of the nozzle seat 1 facing the nozzle 2 and is aligned with the contact block along the sliding direction. When the nozzle 2 is pressed towards the working surface, the nozzle seat 1 slides towards the nozzle 2, and the microswitch moves synchronously with the nozzle seat 1 and gradually approaches the contact block. When the contact block contacts the contact of the microswitch and applies a certain pressure, the contact inside the microswitch closes, and an insurance release signal is sent to the trigger assembly 83. By adjusting the operating force of the microswitch, the pressure value required for the nozzle 2 to fit the working surface can be set to avoid accidental touch. And the mechanical contact does not depend on electronic components and is suitable for complex electromagnetic environments (such as welding workshops) or high-humidity scenarios.

[0067] Refer to Figure 5 As shown, in some embodiments, the nozzle device further includes a gun clip 5. The gun clip 5 has a staple row channel 51. The staple row channel 51 is communicated with the staple feeding channel 21, and the staple 7 at the topmost part in the staple feeding channel 21 extends out of the nozzle 2.

[0068] Specifically, the nail clip 5 is a mechanism for storing the nail studs 7 and feeding them upward into the nail feeding channel 21. It is internally provided with a nail row channel 51 for accommodating multiple nail studs 7 and pushing them sequentially into the nail feeding channel 21 of the nail nozzle 2. The connection between the nail row channel 51 and the nail feeding channel 21 forms a butt joint on the pushing path of the nail stud 7, ensuring that there is no jamming or deviation when the nail stud 7 slides from the nail row channel 51 into the nail feeding channel 21. The nail stud 7 at the topmost position in the nail feeding channel 21 extends out of the nail nozzle 2, that is, the nail head of the nail stud 7 to be fired is located outside the nail nozzle 2. The operator can directly judge the alignment of the nail stud 7 with the target hole position by the naked eye, fundamentally solving the problem of misalignment between the nail stud 7 and the hole position during binding and fixing of the hole position.

[0069] Referring to Figure 6 and Figure 7 As shown, in some embodiments, the nail nozzle device further includes an anti-backward component 6. The anti-backward component 6 includes: a nail blocking bar 61 and a nail blocking bar resetting member 62. The nail blocking bar 61 includes a connecting portion 611 and a limiting portion 612 that are sequentially connected. The connecting portion 611 is rotatably connected to the nail nozzle 2, and the limiting portion 612 extends into the nail feeding channel 21. The nail blocking bar resetting member 62 abuts against the connecting portion 611. Wherein, when the nail pushing block of the nail clip 5 pushes the nail stud 7 towards the nail feeding channel 21, the limiting portion 612 drives the connecting portion 611 to rotate synchronously, and the connecting portion 611 simultaneously compresses the nail blocking bar resetting member 62. When the nail stud 7 passes over the limiting portion 612 and enters the nail feeding channel 21, the nail blocking bar resetting member 62 pushes the connecting portion 611 and the limiting portion 612 to reset. When the nail stud 7 located in the nail feeding channel 21 moves towards the direction of the limiting portion 612, the connecting portion 611 or the limiting portion 612 abuts against the nail nozzle 2 to limit the movement of the nail stud 7 in the nail feeding channel 21 towards the direction of the nail row channel 51.

[0070] Specifically, since the nail stud 7 is in direct contact with the working surface, and at the same time, when the safety contact signal is triggered, the nail stud 7 needs to bear a certain load. In this case, there is a probability that the nail stud 7 will be subjected to a component force in the direction of the nail row channel 51, resulting in the movement of the nail stud 7 towards the nail row channel 51, and further causing the firing pin to be unable to normally strike the tail of the nail stud 7, ultimately resulting in a nail jamming situation.

[0071] To solve the above problems, the nail blocking strip 61 includes a connecting portion 611 and a limiting portion 612. The connecting portion 611 is rotatably connected to the nozzle 2 (such as through a pin shaft or a hinge structure), serving as the supporting and driving part of the nail blocking strip 61. The limiting portion 612 extends from the connecting portion 611 into the nail feeding channel 21, and is used to block the nail 7 from retreating towards the nail row channel 51. One end of the nail blocking strip reset member 62 is fixed to the nozzle 2 or the nozzle seat 1, and the other end abuts against the connecting portion 611 of the nail blocking strip 61 to provide a reset force.

[0072] When the pusher block of the gun clip 5 pushes the nail 7 to move upward into the nail feeding channel 21, the connecting portion 611 drives the limiting portion 612 to rotate synchronously. At the same time, the connecting portion 611 compresses the nail blocking strip reset member 62. After the nail 7 passes over the limiting portion 612 and enters the nail feeding channel 21, that is, the nail driving action is completed, and the nail blocking strip reset member 62 pushes the connecting portion 611 and the limiting portion 612 to reset.

[0073] When the nail 7 located in the nail feeding channel 21 moves towards the limiting portion 612, the connecting portion 611 or the limiting portion 612 abuts against the nozzle 2, that is, the connecting portion 611 abuts against the nozzle 2, or the limiting portion 612 abuts against the nozzle 2, so that the limiting portion 612 cannot move towards the nail row channel 51, thereby achieving the effect of restricting the movement of the nail 7 towards the limiting portion 612.

[0074] With the above structure, when the nail 7 is under pressure again, due to the restriction of the limiting portion 612, the nail 7 that has completed the nail driving cannot move towards the nail row channel 51 anymore, thus effectively solving the problem that the nail 7 may retreat under pressure.

[0075] Refer to Figure 6 and Figure 7 As shown, in some embodiments, one side of the nozzle 2 is provided with a first structural plate 26 and a second structural plate 27. There is a gap for assembling the nail blocking strip 61 between the first structural plate 26 and the second structural plate 27. The connecting portion 611 of the nail blocking strip 61 is assembled in this gap, and the rotating pin 28 sequentially passes through the first structural plate 26, the connecting portion 611 and the second structural plate 27 to form the rotating structure of the nail blocking strip 61. A third assembly pin 613 is provided at one end of the connecting portion 611 away from the limiting portion 612. The nail blocking strip reset member 62 is a spring. One end of the spring is sleeved on the third assembly pin 613, and the other end can be provided with an assembly pin or an assembly groove at the assembly point of the other end of the spring according to needs to ensure the stability of the spring installation and not interfere with the movement of the third assembly pin 613.

[0076] Refer to Figure 6 and Figure 7As shown, further, the first structural plate 26 and the second structural plate 27 are integrally formed with the nozzle 2, ensuring the stability and installation accuracy of the first structural plate 26 and the second structural plate 27.

[0077] In some embodiments, the side of the limiting portion 612 facing the staple row channel 51 is a guiding surface 6121, and the guiding surface 6121 is inclined toward the staple feeding channel 21 from the side close to the connecting portion 611 to the side far from the connecting portion 611.

[0078] Specifically, the side of the limiting portion 612 facing the staple row channel 51 is provided as an inclined surface, and the guiding surface 6121 is inclined toward the staple feeding channel 21 from the side close to the connecting portion 611 to the side far from the connecting portion 611, so that the staple 7 can more easily push the guiding portion to rotate in a direction away from the staple feeding channel 21, thereby facilitating staple feeding.

[0079] Refer to Figure 6 and Figure 7 As shown, in some embodiments, the side of the limiting portion 612 facing the staple feeding channel 21 is a limiting surface 6122. When the limiting portion 612 is in an unrotated state, the limiting surface 6122 is perpendicular to the plane of the upward movement direction of the staple 7, so as to stably support the staple 7 in the staple feeding channel 21 and prevent the staple 7 from shifting due to force.

[0080] Refer to Figure 8 As shown, in some embodiments, the staple feeding channel 21 is provided with a limiting step 22, and the limiting step 22 abuts against at least the tail of one staple 7 in the staple feeding channel 21.

[0081] Specifically, since the staple 7 needs to bear pressure during the triggering process of the insurance signal trigger switch, in order to prevent the staple 7 from retreating along the staple firing direction, the staple feeding channel 21 is provided with a limiting step 22, and the limiting step 22 abuts against at least the tail of one of the staples 7 in the staple feeding channel 21. Since the whole row of staples 7 is generally connected by a paper strip 71, limiting the tail of any staple 7 in the staple feeding channel 21 can prevent the topmost staple 7 from retreating.

[0082] Optionally, the limiting step 22 is arranged corresponding to the second staple 7 in the firing order, that is, the limiting step 22 is arranged corresponding to the staple 7 adjacent to the topmost staple 7. Since the staples 7 are connected by a paper strip 71, limiting the second staple 7 can ensure a better anti-retreat effect on the first staple 7.

[0083] Refer to Figure 2 and Figure 5As shown, in some embodiments, the nozzle base 1 is provided with a first sliding fit portion 13, and the nozzle 2 is provided with a second sliding fit portion 24 that slidably fits with the first sliding fit portion 13.

[0084] Specifically, the nozzle base 1 is provided with a first sliding fit portion 13, and the nozzle 2 is provided with a second sliding fit portion 24. The first sliding fit portion 13 and the second sliding fit portion 24 are slidably mated. Optionally, the first sliding fit portion 13 can be a guiding groove, and the second sliding fit portion 24 can be a slider. The slider slides in the guiding groove to improve the stability of the nozzle 2 during the sliding process on the nozzle base 1.

[0085] Refer to Figures 1 - 10 As shown, the present invention also provides a nail gun, which includes a housing 81, a power device 82, a trigger assembly 83, and the above-mentioned nozzle device. Among them, the power device 82 and the trigger assembly 83 are both assembled on the housing 81. The nozzle base 1 is fixedly connected to the power supply device, and the first trigger member 31 and / or the second trigger member 32 are electrically connected to the trigger assembly 83.

[0086] Specifically, the housing 81 serves as the main frame of the nail gun. The housing 81 is made of high-strength plastic or metal material and is provided with an installation structure for installing the power device 82 and the trigger assembly 83. The front end of the housing 81 is connected to the nozzle device. The power device 82 can be pneumatically driven or electrically driven, which is selected according to actual needs. The trigger assembly 83 is used to receive the firing instruction from the operator and start the power device 82. The trigger assembly 83 is connected to the safety signal trigger switch through mechanical linkage or electrical signal communication, so as to be able to receive the signal of the safety signal trigger switch and ensure the safety during the use of the nail gun.

[0087] Refer to Figure 9 and Figure 10 As shown, in some embodiments, the nail gun further includes a guiding assembly. One end of the guiding assembly is connected to the housing 81, and the other end is connected to the gun clip 5, so that the housing 81 can slide relative to the gun clip 5.

[0088] Specifically, since the nail 7 needs to extend out of the nozzle 2, the gun clip 5 needs to be correspondingly arranged close to the nail outlet of the nozzle 2. To improve the stability of the gun clip 5, the gun clip 5 and the housing 81 are connected through a guiding assembly. The guiding assembly can slide when the housing 81 slides relative to the gun clip 5, so as to ensure the stability of the gun clip 5 and the nozzle 2.

[0089] Further, the guiding assembly can be arranged at one end of the gun clip 5 away from the nozzle 2. One end of the guiding assembly is connected to the side of the housing 81 away from the nozzle seat 1, and the other end is connected to the end of the gun clip 5 away from the nozzle 2. Thus, the upper end of the nail gun is guided through the sliding fit between the nozzle seat 1 and the nozzle 2, and the lower end is guided through the guiding assembly, which can further improve the stability of the gun clip 5 and the nozzle 2.

[0090] Refer to Figure 9 As shown, as an option, the guiding assembly can be a connecting piece 91. One end of the connecting piece 91 is slidably connected to the housing 81, and the other end is fixedly connected to the gun clip 5. Thus, when the housing 81 slides relative to the gun clip 5, the sliding connection between the connecting piece 91 and the housing 81 allows the housing 81 to slide towards the gun clip 5, ensuring the stability of the gun clip 5 on the basis of not affecting the relative movement between the housing 81 and the gun clip 5.

[0091] Refer to Figure 10 As shown, as an option, the guiding assembly includes a pulley 93 and a pulley groove 94. The pulley 93 is fixedly connected to the gun clip 5 through a connecting rod 92. The pulley groove 94 is arranged on the housing 81, and the pulley 93 slides in the pulley groove 94. So that when the housing 81 slides relative to the gun clip 5, the pulley 93 can slide in the pulley groove 94, ensuring the stability of the gun clip 5 on the basis of not affecting the relative movement between the housing 81 and the gun clip 5.

It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present invention.
