Description

Technical Field

[0001] This utility model relates to the field of nail gun technology, and in particular to a nozzle device and a nail gun. Background Technology

[0002] In many fields such as construction, decoration, and woodworking, nail guns are widely used as efficient and convenient fastening tools. They can quickly drive nails into the substrate, achieving a firm connection between various components, greatly improving work efficiency and reducing labor intensity.

[0003] Conventional nail guns typically have a movable crank on the nozzle, which acts as a safety mechanism. During operation, the front end of the crank needs to be positioned against the work surface. Only when the crank is in correct contact with the work surface and reaches a certain pressure or position will the safety switch of the nail gun be released, allowing firing. This design is intended to prevent accidental firing when the nail gun is not properly aligned with the target surface, thus ensuring the safety of the operator.

[0004] However, this conventional structure gradually revealed a significant problem in practical use. Because the front end of the crank is designed to be relatively large—intended to ensure stable positioning on the machined surface and provide a reliable safety function—the nail is located at the center of the crank. This structural layout leads to a serious defect: the operator cannot accurately position the nail using the crank.

[0005] In practical applications, especially when fixing perforated iron plates, it's crucial to accurately position the plate, requiring the nail to precisely penetrate the holes. However, due to the large tip of the crank and the nail's central position, it's difficult for operators to visually and accurately determine the relative position of the nail to the hole when positioning the crank tip on the iron plate. If the operator fires without aligning the nail with the hole, the nail will strike the iron plate directly. Because the nail gun generates tremendous impact force upon firing, the nail is highly likely to bounce off the plate at high speed, posing a risk of cuts, punctures, or even more serious injuries to the operator or others nearby. Furthermore, it may collide with surrounding structural elements or equipment, causing damage or malfunctions. Summary of the Invention

[0006] In order to overcome at least one of the defects described in 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 shot due to the setting of the crank assembly.

[0007] The technical solution adopted by this utility model to solve its problem is:

[0008] A muzzle device, comprising:

[0009] Gun muzzle holder;

[0010] The nozzle has an upper nail channel and is slidably connected to the nozzle seat;

[0011] A safety signal trigger switch includes a first trigger and a second trigger. The first trigger is disposed on the nozzle, and the second trigger is disposed in the direction from the nozzle toward the nozzle seat. The second trigger can move synchronously with the nozzle seat. When the nozzle seat moves relative to the nozzle, the second trigger moves toward the first trigger, so that the first trigger and the second trigger trigger a safety release signal.

[0012] A reset component is connected to the nozzle so that after the nozzle moves relative to the nozzle seat, the nozzle is reset by the action of the reset component.

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

[0014] Alternatively, the first trigger is an abutment block, and the second trigger is a micro switch.

[0015] Furthermore, it also includes a gun clip having a nail row channel that communicates with the upper nail channel, and the topmost nail in the upper nail channel extends out of the gun nozzle.

[0016] Furthermore, it also includes an anti-rollback component, the anti-rollback component comprising:

[0017] A nail-stopping strip, comprising a connecting portion and a limiting portion connected in sequence, wherein the connecting portion is connected to the nozzle and the limiting portion extends into the upper nail channel;

[0018] A pin stop reset component, wherein the pin stop reset component abuts against the connecting portion;

[0019] The limiting part is pushed by the nail in the nail row channel to move outward of the upper nail channel, and the connecting part compresses the nail stop bar reset member at the same time. When the nail passes the limiting part and enters the upper nail channel, the nail stop bar reset member pushes the connecting part and the limiting part to reset.

[0020] Furthermore, it also includes an anti-rollback component, the anti-rollback component comprising:

[0021] A nail-stopping strip, comprising a connecting part and a limiting part connected in sequence, wherein the connecting part is rotatably connected to the nozzle, and the limiting part extends into the upper nail channel;

[0022] A pin stop reset component, wherein the pin stop reset component abuts against the connecting portion;

[0023] When the pusher block of the gun clip pushes the nail into the upper nail channel, the connecting part drives the limiting part to rotate synchronously, and the connecting part simultaneously compresses the nail stop bar reset member. When the nail passes the limiting part and enters the upper nail channel, the nail stop bar reset member pushes the connecting part and the limiting part to reset.

[0024] When the nail in the upper nail channel moves toward the limiting part, the connecting part or the limiting part abuts against the nozzle to restrict the movement of the nail in the upper nail channel toward the nail row channel.

[0025] Furthermore, the limiting part facing the nail channel is a guide surface, and the guide surface is inclined towards the upper nail channel from the side near the connecting part to the side away from the connecting part.

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

[0027] Furthermore, the nozzle seat is provided with a sliding groove, the nozzle is slidably disposed in the sliding groove, the nozzle seat is provided with a limiting guide pin, the nozzle is provided with a limiting guide groove, and one end of the limiting guide pin extends into the limiting guide groove.

[0028] Furthermore, the nozzle seat is provided with a first sliding engagement portion, and the nozzle is provided with a second sliding engagement portion that slides with the first sliding engagement portion.

[0029] A nail gun, comprising:

[0030] case;

[0031] Power unit;

[0032] Trigger assembly;

[0033] The aforementioned muzzle device;

[0034] The power unit and trigger assembly are both mounted on the housing, the nozzle seat is fixedly connected to the power unit, and the first trigger and / or the second trigger are electrically connected to the trigger assembly.

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

[0036] In summary, the nozzle device and nail gun provided by this utility model have the following technical effects:

[0037] 1. A sliding connection is used to connect the nozzle to the nozzle seat. The relative movement between the nozzle and the nozzle seat drives the first and second triggers to trigger the safety release signal according to the change in the relative position between the nozzle and the nozzle seat. This structure replaces the traditional crank assembly, ensuring the safety of the nail gun using this nozzle device.

[0038] 2. The sliding connection between the nozzle and nozzle seat structure replaces the crank assembly, allowing the nozzle to directly contact the working surface. This greatly shortens the distance from the nail to the target point, eliminating the interference of the crank front end on positioning. Operators can intuitively judge the relative position of the nail and the hole, thereby significantly improving the accuracy of nail shooting and avoiding the risk of nail ejection due to positioning deviation.

[0050] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.

[0051] To facilitate understanding of the embodiments of this utility model, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.

[0052] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0054] See Figures 1-10This utility model discloses a gun nozzle device, including: a gun nozzle base 1, a gun nozzle 2, a safety signal trigger switch, and a reset member 4. The gun nozzle 2 has an upper nail channel 21. The gun nozzle 2 is slidably connected to the gun nozzle base 1. The safety signal trigger switch includes a first trigger member 31 and a second trigger member 32. The first trigger member 31 is disposed on the gun nozzle 2, and the second trigger member 32 is disposed in the direction of the gun nozzle 2 toward the gun nozzle base 1. The second trigger member 32 can move synchronously with the gun nozzle base 1. When the gun nozzle base 1 slides toward the gun nozzle 2, the second trigger member 32 moves toward 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 gun nozzle 2, so that after the gun nozzle 2 moves toward the gun nozzle base 1, the gun nozzle 2 is reset by the action of the reset member 4.

[0055] See Figures 1-4 As shown, specifically, the nozzle seat 1 and nozzle 2 are slidably connected, allowing them to slide relative to each other. The nozzle 2 has an upper nail channel 21 to facilitate firing after the subsequent nail 7 is filled. The safety signal trigger switch includes a first trigger 31 and a second trigger 32. The first trigger 31 is located on the nozzle 2 and moves synchronously with the nozzle 2. The second trigger 32 is located in the direction from the nozzle 2 toward the nozzle seat 1 and can move synchronously with the nozzle seat 1. Specifically, the second trigger 32 can be located on the nozzle seat 1 or the housing 81 of the nail gun to enable the nozzle seat 1 to move toward the nozzle 2. When the nozzle seat 1 moves toward the nozzle 2, the second trigger 32 moves synchronously toward the nozzle 2, that is, toward the first trigger 31. When the first trigger 31 and the second trigger 32 approach or contact each other, the safety signal is triggered to release. After the nozzle 2 completes its sliding, the reset member 4 pushes the nozzle 2 back to its initial position through elastic force. The reset element 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 muzzle 2 with the target point, then push the muzzle mount 1 and the second trigger 32 toward the target point. Once the first trigger 31 and the second trigger 32 can trigger the safety release signal, pull the trigger to complete normal firing. After firing, the reset member 4 pushes the muzzle 2 to reset.

[0058] It should be noted that if the first trigger 31 and the second trigger 32 are contact trigger switches, the nozzle holder 1 can move to the point where the second trigger 32 contacts the first trigger 31; if the first trigger 31 and the second trigger 32 are non-contact trigger switches, the nozzle holder 1 can move to the point where the second trigger 32 and the first trigger 31 are in a non-contact state to trigger the safety release signal, and no limitation is made here.

[0059] See Figure 2 and Figure 3 As shown, in some embodiments, the nozzle 2 is provided with a first mounting pin 25 at one end facing the nozzle seat 1, and the nozzle seat 1 is provided with a second mounting pin 14 corresponding to the nozzle 2. The reset member 4 is a spring, with one end of the spring sleeved on the first mounting pin 25 and the other end sleeved on the second mounting pin 14, thereby facilitating the assembly of the spring and maintaining the stability of the spring during repeated compression and release.

[0060] See Figure 2 and Figure 4 As 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 toward the nozzle 2, the Hall element moves synchronously with the nozzle seat 1. When the Hall element approaches the magnet, the magnet triggers the Hall element to release the safety signal.

[0061] 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 needs and can be selected as a small cylindrical or rectangular block to facilitate the combination and installation of the magnet and the nozzle 2. The second trigger 32 is a Hall element, which is installed on the side of the nozzle seat 1 facing the nozzle 2 and aligned with the magnet along the sliding direction. When the magnet approaches the Hall element, a safety release signal is triggered. By using a combination of Hall element and magnet, the Hall element is smaller in size and occupies far less space than traditional mechanical contact structures, which facilitates the miniaturization design of the nozzle device. Furthermore, the combination of Hall element and magnet can reduce mechanical wear.

[0062] In other embodiments, the first trigger 31 is an abutment block, and the second trigger 32 is a micro switch. When the nozzle seat 1 moves toward the nozzle 2, the contact of the micro switch abuts against the abutment block to trigger a safety release signal.

[0063] Specifically, when the first trigger 31 is an abutment block, the abutment block can be integrally formed with the nozzle 2. The second trigger 32 is a micro switch, which is installed on the side of the nozzle seat 1 facing the nozzle 2 and aligned with the abutment block along the sliding direction. When the nozzle 2 is pressed against the working surface, the nozzle seat 1 slides towards the nozzle 2, and the micro switch moves synchronously with the nozzle seat 1, gradually approaching the abutment block. When the abutment block contacts the contacts of the micro switch and applies a certain pressure, the contacts inside the micro switch close, sending a release signal to the trigger assembly 83. By adjusting the actuating force of the micro switch, the pressure value required for the nozzle 2 to contact the working surface can be set, avoiding accidental activation. Furthermore, the mechanical contacts do not rely on electronic components, making them suitable for complex electromagnetic environments (such as welding workshops) or high-humidity scenarios.

[0064] See Figure 5 As shown, in some embodiments, the nozzle device further includes a clip 5 having a nail row channel 51 that communicates with the upper nail channel 21, and the topmost nail 7 in the upper nail channel 21 extends out of the nozzle 2.

[0065] Specifically, the clip 5 is a mechanism for storing the nails 7 and supplying nails to the upward nailing channel 21. It has an internal nail row channel 51 for accommodating multiple nails 7 and sequentially pushing them to the upward nailing channel 21 of the nozzle 2. The nail row channel 51 and the upward nailing channel 21 are connected, forming an abutment on the nail 7 pushing path, ensuring that the nails 7 slide into the upward nailing channel 21 without jamming or shifting. The topmost nail 7 in the upward nailing channel 21 extends out of the nozzle 2, meaning the head of the nail 7 to be fired is outside the nozzle 2. The operator can directly visually judge the alignment of the nail 7 with the target hole, fundamentally solving the problem of inaccurate alignment between the nail 7 and the hole when fixing the nails.

[0066] See Figure 6 and Figure 7As shown, in some embodiments, the nozzle device further includes an anti-recoil assembly 6, which includes a nail-stopping strip 61 and a nail-stopping strip reset member 62. The nail-stopping strip 61 includes a connecting portion 611 and a limiting portion 612 connected in sequence. The connecting portion 611 is rotatably connected to the nozzle 2, and the limiting portion 612 extends into the upper nail channel 21. The nail-stopping strip reset member 62 abuts against the connecting portion 611. When the nail-pushing block of the clip 5 pushes the nail 7 towards the upper nail channel 21, the limiting portion 612 drives... The connecting part 611 rotates synchronously, and the connecting part 611 simultaneously compresses the nail stop bar reset member 62. When the nail 7 passes the limiting part 612 and enters the upper nail channel 21, the nail stop bar reset member 62 pushes the connecting part 611 and the limiting part 612 to reset. When the nail 7 located in the upper nail channel 21 moves toward the limiting part 612, the connecting part 611 or the limiting part 612 abuts against the nozzle 2 to restrict the movement of the nail 7 in the upper nail channel 21 toward the nail row channel 51.

[0067] Specifically, since the nail 7 is in direct contact with the working surface, and the nail 7 needs to bear a certain load when the safety contact signal is triggered, the nail 7 may be subjected to a component force in the direction of the nail row channel 51, which will cause the nail 7 to move in the direction of the nail row channel 51, thus causing the firing pin to fail to strike the tail of the nail 7 normally, which will eventually lead to the nail getting stuck.

[0068] To address the aforementioned issues, the nail stop bar 61 includes a connecting portion 611 and a limiting portion 612. The connecting portion 611 is rotatably connected to the nozzle 2 (e.g., via a pin or hinge structure), serving as both the support and drive component of the nail stop bar 61. The limiting portion 612 extends from the connecting portion 611 into the upper nail channel 21, preventing the nails 7 from retracting towards the nail row channel 51. One end of the nail stop bar reset member 62 is fixed to the nozzle 2 or nozzle seat 1, while the other end abuts against the connecting portion 611 of the nail stop bar 61, providing a reset force.

[0069] When the pusher block of the clip 5 pushes the nail 7 to move upward into the nailing channel 21, the connecting part 611 drives the limiting part 612 to rotate synchronously. At the same time, the connecting part 611 compresses the nail stop bar reset member 62. When the nail 7 passes the limiting part 612 and enters the nailing channel 21, the nailing action is completed. The nail stop bar reset member 62 pushes the connecting part 611 and the limiting part 612 to reset.

[0070] When the nail 7 located in the upper nail channel 21 moves toward the limiting part 612, the connecting part 611 or the limiting part 612 abuts against the nozzle 2, that is, the connecting part 611 abuts against the nozzle 2, or the limiting part 612 abuts against the nozzle 2, thereby preventing the limiting part 612 from moving toward the nail row channel 51, thus achieving the effect of restricting the movement of the nail 7 toward the limiting part 612.

[0071] With the above structure, when the nail 7 is subjected to pressure again, due to the restriction of the limiting part 612, the nail 7 that has been nailed can no longer move toward the nail row channel 51, thus effectively solving the problem of the nail 7 retracting under pressure.

[0072] See Figure 6 and Figure 7 As shown, in some embodiments, the nozzle 2 has a first structural plate 26 and a second structural plate 27 on one side. A gap exists between the first structural plate 26 and the second structural plate 27 for assembling a stop pin strip 61. The connecting portion 611 of the stop pin strip 61 is fitted into this gap. A rotating pin 28 passes sequentially through the first structural plate 26, the connecting portion 611, and the second structural plate 27 to form a rotating structure for the stop pin strip 61. A third mounting pin 613 is provided at the end of the connecting portion 611 away from the limiting portion 612. The stop pin strip reset member 62 is a spring. One end of the spring is sleeved on the third mounting pin 613, and the other end can be fitted with a mounting pin or mounting groove at the mounting point on the other end of the spring as needed to ensure the stability of the spring installation and to avoid interfering with the movement of the third mounting pin 613.

[0073] See Figure 6 and Figure 7 As shown, the first structural plate 26 and the second structural plate 27 are integrally formed with the nozzle 2 to ensure the stability and installation accuracy of the first structural plate 26 and the second structural plate 27.

[0074] In some embodiments, the limiting portion 612 is a guide surface 6121 facing the nail channel 51, and the guide surface 6121 is inclined from the side near the connecting portion 611 to the side away from the connecting portion 611 in the direction of the upper nail channel 21.

[0075] Specifically, the limiting part 612 is set as an inclined surface on the side facing the nail channel 51, and the guide surface 6121 is inclined from the side near the connecting part 611 to the side away from the connecting part 611 towards the nail channel 21, so that the nail 7 can more easily push the guide part to rotate in the direction away from the nail channel 21, thereby facilitating nailing.

[0076] See Figure 6 and Figure 7As shown, in some embodiments, the limiting part 612 facing the upper nail channel 21 is a limiting surface 6122. When the limiting part 612 is in a non-rotating state, the limiting surface 6122 is a plane perpendicular to the upper nail movement direction of the nail 7, thereby providing stable support for the nail 7 in the upper nail channel 21 and preventing the nail 7 from shifting under force.

[0077] See Figure 8 As shown, in some embodiments, the upper nail channel 21 is provided with a limiting step 22, which abuts against at least the tail of one of the gun nails 7 in the upper nail channel 21.

[0078] Specifically, since the nail 7 needs to withstand pressure during the triggering of the safety signal trigger switch, in order to prevent the nail 7 from retreating along the firing direction of the nail 7, the upper nail channel 21 is provided with a limiting step 22. The limiting step 22 abuts against the tail of at least one of the nails 7 in the upper nail channel 21. Since the entire row of nails 7 is generally connected by paper strips 71, limiting the tail of any nail 7 in the upper nail channel 21 can prevent the topmost nail 7 from retreating.

[0079] Optionally, the limiting step 22 is set to correspond to the second nail 7 in the firing sequence, that is, the limiting step 22 is set to correspond to the nail 7 adjacent to the topmost nail 7. Since the nails 7 are connected by paper strips 71, limiting the second nail 7 can ensure a better anti-backward effect for the first nail 7.

[0080] See Figure 2 and Figure 5 As shown, in some embodiments, the nozzle seat 1 is provided with a sliding groove 11, the nozzle 2 is slidably disposed in the sliding groove 11, the nozzle seat 1 is provided with a limiting guide pin 12, the nozzle 2 is provided with a limiting guide groove 23, and one end of the limiting guide pin 12 extends into the limiting guide groove 23.

[0081] Specifically, the nozzle holder 1 is provided with a groove 11, and the nozzle 2 slides within the groove 11, ensuring stability during the relative sliding process between the nozzle 2 and the nozzle holder 1. The nozzle holder 1 is provided with a limiting guide pin 12, and the nozzle 2 is provided with a limiting guide groove 23, with one end of the limiting guide pin 12 extending into the limiting guide groove 23. During the sliding process of the nozzle 2 relative to the nozzle holder 1, the limiting guide pin 12 slides synchronously within the limiting guide groove 23, providing guidance for the relative sliding of the nozzle 2 and the nozzle holder 1. The length of the limiting guide groove 23 can be selected to be the same as the length of the relative movement between the nozzle 2 and the nozzle seat 1, so that when the nozzle 2 and the nozzle seat 1 are in the compressed state, the limiting guide pin 12 abuts against the side wall of one end of the limiting guide groove 23, thereby ensuring the stable triggering of the first trigger 31 and the second trigger 32 during the nail firing process; when the nozzle 2 and the nozzle seat 1 are in the initial state, the limiting guide pin 12 abuts against the side wall of the other end of the limiting guide groove 23, thereby preventing the nozzle 2 from coming out of the slide groove 11 of the nozzle seat 1.

[0082] Of course, the length of the limiting guide groove 23 can also be greater than the relative movement length of the nozzle 2 and the nozzle seat 1, as long as it can prevent the nozzle 2 from coming out of the nozzle seat 1, and no limitation is made here.

[0083] See Figure 2 and Figure 5 As shown, in some embodiments, the nozzle seat 1 is provided with a first sliding engagement portion 13, and the nozzle 2 is provided with a second sliding engagement portion 24 that slides with the first sliding engagement portion 13.

[0084] Specifically, the nozzle holder 1 is provided with a first sliding engagement part 13, and the nozzle 2 is provided with a second sliding engagement part 24. The first sliding engagement part 13 and the second sliding engagement part 24 are slidably engaged. Optionally, the first sliding engagement part 13 can be a guide groove, and the second sliding engagement part 24 can be a slider. The slider slides in the guide groove to improve the stability of the nozzle 2 during the sliding process on the nozzle holder 1.

[0085] See Figures 1-10 As shown, this utility model also provides a nail gun, including a housing 81, a power unit 82, a trigger assembly 83 and the above-mentioned nozzle device, wherein the power unit 82 and the trigger assembly 83 are both mounted on the housing 81, the nozzle seat 1 is fixedly connected to the power unit 82, and the first trigger 31 and / or the second trigger 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 and has a mounting structure for the power unit 82 and trigger assembly 83. The front end of the housing 81 is connected to the nozzle assembly. The power unit 82 can be pneumatically or electrically driven, depending on the actual needs. The trigger assembly 83 receives the operator's firing command and activates the power unit 82. The trigger assembly 83 is connected to a safety signal trigger switch via mechanical linkage or electrical signal communication, thus receiving the safety signal trigger switch signal to ensure safety during the use of the nail gun.

[0087] See Figure 9 and Figure 10 As shown, in some embodiments, the nail gun further includes a guide assembly, one end of which is connected to the housing 81 and the other end of which 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 clip 5 needs to be positioned close to the nail outlet of the nozzle 2. To improve the stability of the clip 5, the clip 5 is connected to the housing 81 through a guide assembly. The guide assembly can slide when the housing 81 slides relative to the clip 5, thereby ensuring the stability of the clip 5 and the nozzle 2.

[0089] Furthermore, the guide component can be located at the end of the gun clip 5 away from the nozzle 2. One end of the guide component 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. This allows the upper end of the nail gun to be guided by the sliding engagement of the nozzle seat 1 and the nozzle 2, and the lower end to be guided by the guide component, which can further improve the stability of the gun clip 5 and the nozzle 2.

[0090] See Figure 9 As shown, optionally, the guide component can be an adapter piece 91, one end of which is slidably connected to the housing 81 and the other end is fixedly connected to the gun clip 5. This allows the adapter piece 91 to slide relative to the gun clip 5 while the housing 81 is sliding, thus enabling the housing 81 to slide toward the gun clip 5. This ensures the stability of the gun clip 5 without affecting the relative movement between the housing 81 and the gun clip 5.

[0091] See Figure 10 As shown, optionally, the guide assembly includes a pulley 93 and a pulley groove 94. The pulley 93 is fixedly connected to the gun clip 5 via a connecting rod 92. The pulley groove 94 is provided 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 without affecting the relative movement between the housing 81 and the gun clip 5.
