Description

Technical Field

[0001] This application belongs to the field of power tool technology, specifically relating to a nail gun. Background Technology

[0002] Nail guns are a common power tool widely used in construction, furniture manufacturing, automobile manufacturing and other fields.

[0003] In related technologies, the firing pin of a nail gun is connected to a power mechanism, which provides power to the firing pin to strike it. However, because the power mechanism and the firing pin are rigidly connected, when the power mechanism applies power to the firing pin, the firing pin will directly bear a large impact force, which can easily cause deformation or even damage. Furthermore, while the power mechanism applies a large impact force to the firing pin, some of the impact force will be transmitted to the entire nail gun structure, making the entire nail gun vibrate significantly during use. This can cause discomfort to the operator's hands, thus affecting the operator's user experience. Utility Model Content

[0004] The purpose of this application is to provide a nail gun that can solve the problems in related technologies where the power mechanism and the firing pin are rigidly connected, causing the firing pin to be easily deformed or damaged due to large impact forces, and resulting in significant vibration of the entire nail gun during use.

[0005] In a first aspect, embodiments of this application provide a nail gun, the nail gun comprising: Gun body; A firing pin is movably disposed on the gun body, and the firing pin can move between a raised position and a firing position; A power mechanism is disposed in the gun body. The power mechanism is connected to the firing pin through a flexible transmission component. The power mechanism is used to drive the flexible transmission component to move, thereby moving the firing pin from the lifting position to the firing position, so that the firing pin drives the fixed nail to be fired from the nozzle of the nail gun.

[0006] Secondly, embodiments of this application also provide a nail gun, the nail gun comprising: Gun body; A firing pin is movably disposed on the gun body, and the firing pin can move between a firing position and a raised position; A firing pin connector is connected to the firing pin, and the firing pin connector is movably disposed within the gun body; A lifting mechanism is disposed inside the gun body. The lifting mechanism includes a lifting member that can switch between a first state and a second state. When the lifting member is in the first state, the lifting member can be connected to the firing pin connector and can push the firing pin connector to move the firing pin so that the firing pin moves to the lifting position; When the lifting member is in the second state, the lifting member avoids the firing pin connector, allowing the firing pin connector to move toward the nozzle of the nail gun, so that the firing pin moves to the firing position.

[0007] In this embodiment, the power mechanism is connected to the firing pin via a flexible transmission component. Because the flexible transmission component possesses certain flexibility and buffering characteristics, when the power mechanism drives it, the component can absorb and disperse the impact force to a certain extent, reducing the instantaneous impact force on the firing pin. This reduces the likelihood of the firing pin deforming or being damaged due to excessive force. Simultaneously, during power transmission, the flexible transmission component can absorb and dissipate some of the vibration energy generated by the power mechanism, preventing this energy from being directly transmitted to the nail gun body. This reduces the overall vibration of the nail gun during use, effectively improving operator comfort. Attached Figure Description

Detailed Implementation

[0010] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0011] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0012] The nail gun provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0013] refer to Figures 1-24 The present application provides a nail gun, which may include a gun body 100, a firing pin 200 and a power mechanism 300. The firing pin 200 is movably disposed in the gun body 100 and can move between a raised position and a firing position. The power mechanism 300 may be disposed in the gun body 100 and can provide power to the firing pin 200 to drive the firing pin 200 from the raised position to the firing position, that is, drive the firing pin 200 to move toward the nozzle 110 of the nail gun, thereby firing out the nail.

[0014] The power mechanism 300 can be connected to the firing pin 200 through the flexible transmission component 400. The power mechanism 300 can be used to drive the flexible transmission component 400 to move, so as to move the firing pin 200 from the lifting position to the firing position, so that the firing pin 200 drives the fixed nail to be fired from the nozzle 110 of the nail gun, thereby realizing the nailing operation.

[0015] In this embodiment, because the flexible transmission component 400 has certain flexibility and buffering characteristics, when the power mechanism 300 drives the flexible transmission component 400 to move, the flexible transmission component 400 can absorb and disperse the impact force to a certain extent, reducing the instantaneous impact force borne by the firing pin 200, thereby reducing the possibility of the firing pin 200 deforming or being damaged due to excessive force. At the same time, during the power transmission process, the flexible transmission component 400 can absorb and consume some of the vibration energy generated by the power mechanism 300, thereby preventing this energy from being directly transmitted to the gun body 100, thus reducing the vibration of the entire nail gun during use, and effectively improving the operator's comfort when using the nail gun.

[0016] In an optional embodiment of this application, the flexible transmission member 400 may include a transmission belt. For example... Figure 3 As shown, the nail gun may also include a limiting member 500, which may be positioned close to the nozzle 110. A portion of the transmission belt may be connected to the power mechanism 300, and another portion of the transmission belt may bypass the limiting member 500 on the side opposite to the power mechanism 300 and be connected to the firing pin 200. With this configuration, when the firing pin 200 moves, the transmission belt, constrained by the limiting member 500, can only move along the trajectory defined by the limiting member 500, ensuring that the transmission belt remains taut at all times. This allows for a transmission connection between the transmission belt and the firing pin 200 and the power mechanism 300, thereby ensuring that the power mechanism 300 can apply power to the firing pin 200 in the direction of the nozzle 110.

[0017] In other embodiments, the flexible transmission member 400 may not include a transmission belt; for example, the flexible transmission member 400 may include a flexible buffer block. Furthermore, the nail gun may not include the limiting member 500.

[0018] In optional embodiments, such as Figures 3-5 , Figure 7 and Figure 8 As shown, the nail gun may also include a firing pin connector 600 and a power connector 700. The firing pin connector 600 can be connected to the firing pin 200 and is movably disposed within the gun body 100. A transmission belt can be connected to the firing pin connector 600. The power connector 700 is movably disposed within the gun body 100 and can be connected to both the transmission belt and the power mechanism 300.

[0019] When the firing pin 200 moves in the direction from the firing position to the lifting position, that is, when the firing pin 200 moves away from the nozzle 110, the firing pin connector 600 can drive the power connector 700 to move in the direction from the lifting position to the firing position via the transmission belt, that is, drive the power connector 700 to move toward the nozzle 110 so that the power mechanism 300 stores energy.

[0020] In this embodiment, the firing pin connector 600 drives the power connector 700 toward the nozzle 110 via a transmission belt. This allows the energy generated during the firing pin 200's lifting process to be transferred to the power mechanism 300, enabling the power mechanism 300 to store energy. Upon subsequent firing, the power mechanism 300 can release the stored energy to drive the firing pin 200 forward quickly, effectively improving energy utilization efficiency and reducing energy loss. Furthermore, since the power mechanism 300 can utilize the energy recovered during the firing pin 200's lifting process for energy storage, it reduces dependence on external power sources, thereby lowering the overall energy consumption of the nail gun.

[0021] In other embodiments, when the firing pin 200 moves in the direction from the firing position to the lifting position, the firing pin connector 600 may not be able to drive the power connector 700 toward the nozzle 110 via the transmission belt.

[0022] In optional embodiments, such as Figure 3As shown, the limiting member 500 may include a first rolling member 510 and a second rolling member 520. Both the first rolling member 510 and the second rolling member 520 can be rotatably connected to the gun body 100. Furthermore, the first rolling member 510 and the second rolling member 520 can be located on opposite sides of the firing pin connector 600 in a first direction. The transmission belt can pass over the side of the first rolling member 510 facing away from the power connector 700 and the side of the second rolling member 520 facing away from the power connector 700, respectively. Here, the first direction may intersect with the direction from the firing position to the lifting position; for example, the first direction may be the width direction of the nail gun. In this embodiment, since the first rolling element 510 and the second rolling element 520 are rotatably connected to the gun body 100, when the transmission belt passes around them and moves away from the power connector 700, the first rolling element 510 and the second rolling element 520 will rotate with the movement of the transmission belt. This can create rolling friction between the transmission belt and the limiting member 500, effectively reducing the friction between the transmission belt and the limiting member 500, making the movement of the transmission belt smoother, and helping to extend the service life of the transmission belt. Furthermore, since the first rolling element 510 and the second rolling element 520 are located on both sides in the first direction, the first rolling element 510 and the second rolling element 520 can play a role in positioning the transmission belt on both sides. When the transmission belt is subjected to some external force interference or uneven tension during the movement, the first rolling element 510 and the second rolling element 520 can limit the lateral displacement of the transmission belt and prevent the transmission belt from running off-track.

[0023] Of course, the limiting member 500 may not include the first rolling member 510 and the second rolling member 520. For example, the limiting member 500 may include a fixed post, and the transmission belt may be connected to the striker 200 by passing around the fixed post on the side away from the power mechanism 300.

[0024] In some embodiments, such as Figure 9 and Figure 10As shown, the transmission belt can be connected to the striker connector 600 via a third rolling element 620. Specifically, the third rolling element 620 can be rotatably connected to the striker connector 600. The transmission belt can sequentially wrap around the side of the first rolling element 510 away from the power connector 700, the side of the third rolling element 620 close to the power connector 700, and the side of the second rolling element 520 away from the power connector 700 to achieve the connection between the transmission belt and the striker connector 600. In this embodiment, the method of connecting the transmission belt and the striker connector 600 by the transmission belt wrapping around the third rolling element 620, compared to the method of fixed connection between the transmission belt and the striker connector 600, can prevent stress concentration at the contact point between the transmission belt and the striker connector 600, thereby making the transmission belt more evenly stressed, which is beneficial to extending the service life of the transmission belt and improving the reliability of the connection between the transmission belt and the striker connector 600. Of course, the transmission belt can also be directly fixedly connected to the striker connector 600.

[0025] Optionally, such as Figure 9 and Figure 10 As shown, the transmission belt can be connected to the power connector 700 via the fourth rolling element 710 and the fifth rolling element 720. Specifically, the fourth rolling element 710 and the fifth rolling element 720 can be respectively disposed on both sides of the power connector 700 in the first direction. The end of the transmission belt can be fixedly connected to the gun body 100, and the transmission belt can bypass the fourth rolling element 710 and the fifth rolling element 720 on the side away from the nozzle 110 to achieve the connection between the transmission belt and the power connector 700. This arrangement, compared to the fixed connection between the transmission belt and the power connector 700, can prevent stress concentration at the contact point between the transmission belt and the power connector 700, thereby making the transmission belt more evenly stressed, which is beneficial to extending the service life of the transmission belt and improving the reliability of the connection between the transmission belt and the power connector 700. In addition, since the fourth rolling element 710 and the fifth rolling element 720 can be respectively disposed on both sides of the power connector 700 in the first direction, the power connector 700 is subjected to balanced forces. Of course, the transmission belt can also be directly fixedly connected to the power connector 700.

[0026] In this embodiment, as Figure 9 and Figure 10 As shown, the first end of the transmission belt can be connected to the gun body 100, and the second end of the transmission belt can sequentially pass over the side of the fourth rolling member 710 away from the nozzle 110, the side of the first rolling member 510 away from the power connector 700, the side of the third rolling member 620 close to the power connector 700, the side of the second rolling member 520 away from the power connector 700, and the side of the fifth rolling member 720 away from the nozzle 110 before being connected to the gun body 100.

[0027] In optional embodiments, such as Figure 6As shown, a guide rail 130 can be provided inside the gun body 100. The guide rail 130 can extend along the direction from the firing position to the lifting position, and the firing pin connector 600 can be slidably connected to the guide rail 130. In this embodiment, the guide rail 130 can guide the firing pin connector 600, ensuring that the firing pin connector 600 can only move in the direction specified by the guide rail 130, thereby enabling the firing pin 200 to move accurately in the required direction and preventing the firing pin 200 from deviating during movement.

[0028] Of course, the guide rail 130 may not be installed inside the gun body 100.

[0029] Optionally, such as Figure 6 As shown, the guide rail 130 may include a first guide rail 131 and a second guide rail 132. Both the first guide rail 131 and the second guide rail 132 can extend along the direction from the firing position to the lifting position. The first guide rail 131 and the second guide rail 132 can be spaced apart along a second direction. Here, the second direction can intersect the direction from the firing position to the lifting position and intersect the first direction. Specifically, the second direction can be perpendicular to the direction from the firing position to the lifting position and perpendicular to the first direction. For example, the second direction can be a vertical direction. The opposing sides of the firing pin connector 600 can be slidably connected to the first guide rail 131 and the second guide rail 132, respectively. In this embodiment, the first guide rail 131 and the second guide rail 132 can provide double-sided support for the firing pin connector 600, making the firing pin connector 600 more stable during movement, reducing the shaking and vibration of the firing pin connector 600 during movement, and thus helping to reduce the vibration of the nail gun during use.

[0030] In this embodiment, as Figure 2 As shown, the nail gun may further include a first fixing frame 140 and a second fixing frame 150. Both the first fixing frame 140 and the second fixing frame 150 can be disposed within the gun body 100. The first fixing frame 140 can be connected to the nozzle 110, and the second fixing frame 150 can be connected to the gun body 100. The first end of the first guide rail 131 and the first end of the second guide rail 132 can both be connected to the first fixing frame 140, and the second end of the first guide rail 131 and the second end of the second guide rail 132 can both be connected to the second fixing frame 150. The first rolling element 510 and the second rolling element 520 mentioned above can both be connected to the first guide rail 131 and the first fixing frame 140 through the rotating shaft 501 to realize the connection between the limiting element 500 and the gun body 100. The power connector 700 mentioned above can be slidably connected to the second fixing frame 150 to realize the movable connection between the power connector 700 and the gun body 100. Both ends of the transmission belt can be connected to the second fixed frame 150 to achieve the connection between the transmission belt and the gun body 100.

[0031] In optional embodiments, such as Figure 7 , Figure 9 and Figure 16 As shown, a first buffer 1000 can be provided on the side of the nozzle 110 facing the power mechanism 300, and the firing pin connector 600 can contact the first buffer 1000. With this configuration, when the firing pin 200 moves towards the nozzle 110 and fires the nail, the first buffer 1000 can buffer the firing pin connector 600, thereby reducing the impact force of the firing pin connector 600 on the nozzle 110. This prevents the firing pin connector 600 and / or the nozzle 110 from deforming or even being damaged due to excessive impact force, and absorbs some of the impact energy of the firing pin connector 600, effectively reducing vibration transmission and making the nail gun more stable during operation, thus further improving the operator's experience. For example, the first buffer 1000 can be disposed within the first fixing frame 140.

[0032] And, as Figure 16 As shown, the first buffer 1000 may be provided with a relief groove 1020 for avoiding the impact pin 200, so as to avoid interfering with the movement of the impact pin 200.

[0033] In other embodiments, the first buffer 1000 may not be provided on the firing pin connector 600.

[0034] Optionally, such as Figure 16 As shown, the first buffer 1000 may be provided with a through hole 1010, which can penetrate the first buffer 1000 in the direction from the firing position to the lifting position, that is, the through hole 1010 can penetrate the first buffer 1000 in the direction of movement of the firing pin 200. With this configuration, when the firing pin connector 600 impacts the first buffer 1000, the through hole 1010 provides additional space for the deformation of the first buffer 1000, so that the first buffer 1000 will be compressed and deformed in the direction of the through hole 1010 under pressure, thereby enabling the first buffer 1000 to absorb more impact energy and withstand greater impact force.

[0035] Of course, the first buffer 1000 may not have a through hole 1010.

[0036] In optional embodiments of this application, such as Figure 5As shown, the power mechanism 300 may include a torsion spring 310. The first torsion arm 311 of the torsion spring 310 can be connected to the gun body 100, and the second torsion arm 312 of the torsion spring 310 can be connected to the power connector 700. This configuration eliminates the need for an additional power source for the power mechanism 300, effectively reducing the energy consumption of the nail gun. Simultaneously, when the nail gun is triggered, the elastic potential energy stored in the torsion spring 310 is instantly converted into power, which is quickly transmitted to the firing pin 200 via the power connector 700, causing the firing pin 200 to strike rapidly and complete the nailing action. Furthermore, due to the relatively simple structure and low cost of the torsion spring 310, the manufacturing cost of the nail gun can be effectively reduced.

[0037] In other embodiments, the power mechanism 300 may not include the torsion spring 310. For example, the power mechanism 300 may include a cylinder, and the piston rod of the cylinder may be connected to the flexible transmission member 400.

[0038] Optionally, such as Figure 5 As shown, the power mechanism 300 can be located on the side of the gun body 100 away from the nozzle 110, that is, the power mechanism 300 can be located on the rear side of the nail gun. This arrangement makes it easier for the power mechanism 300 to drive the transmission belt, and the power mechanism 300 does not need to occupy the space of the handle 120 of the nail gun, which helps to reduce the size of the handle 120 and make it easier for the operator to hold.

[0039] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, a fixed shaft 160 can be provided inside the gun body 100. The fixed shaft 160 can be located near the side of the gun body 100 away from the muzzle 110, and the torsion spring body of the torsion spring 310 can be sleeved on the fixed shaft 160. In this way, the torsion spring 310 can be fixed on the side of the gun body 100 away from the muzzle 110.

[0040] In optional embodiments, such as Figure 5 As shown, the power mechanism 300 may include at least two torsion springs 310, each torsion spring 310 being distributed along a first direction. The first torsion arm 311 of each torsion spring 310 can be connected to the gun body 100, and the second torsion arm 312 of each torsion spring 310 can be connected to the power connector 700. The first direction may intersect the direction from the firing position to the lifting position. This arrangement allows the torsion springs 310 to work together, significantly increasing the total output torque of the power mechanism 300. Furthermore, during the storage and release of energy, the distribution of the torsion springs 310 along the first direction ensures that energy is more evenly distributed to all parts of the nail gun, preventing localized energy concentration and reducing impacts caused by sudden energy changes, thus effectively reducing nail gun vibration.

[0041] In other embodiments, the power mechanism 300 may also include only a torsion spring 310.

[0042] In this embodiment, the power mechanism 300 may include two torsion springs 310, which may be evenly distributed along a first direction, i.e., the two torsion springs 310 may be symmetrical about the center line of the power connector 700. This arrangement can balance the forces on the nail gun and the power connector 700, thereby reducing the vibration of the nail gun.

[0043] In optional embodiments, such as Figure 2 As shown, the second torsion arm 312 can be connected to the power coupling 700 via the connecting assembly 320, such as... Figure 5 As shown, the connecting assembly 320 may include a torsion arm connecting portion 321 and a connecting rod 322. The torsion arm connecting portion 321 can be connected to the first torsion arm 311; both ends of the connecting rod 322 can be rotatably connected to the torsion arm connecting portion 321 and the power connector 700, respectively. This configuration allows the linear motion of the power connector 700 to be converted into the torsional motion of the torsion spring 310, and vice versa, thereby meeting the working requirements of the nail gun. Furthermore, it prevents the second torsion arm 312 from bending and deforming under stress during the movement of the power connector 700, thus extending the service life of the torsion spring 310.

[0044] In other embodiments, the second torsion arm 312 may not be connected to the power connector 700 via the connecting assembly 320; the second torsion arm 312 may be directly connected to the power connector 700.

[0045] In optional embodiments, such as Figures 4-11 As shown, the nail gun may also include a second buffer 800, which can be connected to the gun body 100, and the second buffer 800 can be located on the side of the power mechanism 300 opposite to the nozzle 110. Figure 13 As shown, when the firing pin 200 is in the fired position, the torsion arm connection 321 contacts the second buffer 800. This arrangement reduces the impact force on the entire nail gun body 100 when the torsion spring 310 returns to its initial state, thereby reducing the vibration of the entire nail gun.

[0046] like Figure 13 As shown, after the power connector 700 moves towards the nozzle 110, the power connector 700 can drive the torsion spring 310 to rotate, causing the torsion arm connection 321 to separate from the second buffer 800, and allowing the torsion spring 310 to store energy, so as to have the following effect: Figure 13 The rotational trend in the direction of the middle arrow a.

[0047] In other embodiments, the nail gun may also exclude the second buffer 800.

[0048] This application also provides a nail gun, such as... Figure 5 As shown, the nail gun may include a gun body 100, a firing pin 200, a firing pin connector 600, and a lifting mechanism 900. The nail gun in this embodiment can be any of the nail guns described in the above embodiments.

[0049] The firing pin 200 is movably disposed on the gun body 100 and can move between a firing position and a raised position; the firing pin connector 600 can be connected to the firing pin 200 and is movably disposed within the gun body 100; the lifting mechanism 900 can be disposed within the gun body 100 and can include a lifting member 910, which can switch between a first state and a second state.

[0050] When the lifting member 910 is in the first state, the lifting member 910 can be connected to the firing pin connector 600 and can push the firing pin connector 600 to move the firing pin 200 so that the firing pin 200 moves to the lifting position and realizes the lifting of the firing pin 200. When the lifting member 910 is in the second state, the lifting member 910 avoids the firing pin connector 600, so that the firing pin connector 600 can move toward the nozzle 110 of the gun body 100, so that the firing pin 200 moves to the firing position.

[0051] In this embodiment, the lifting member 910 pushes the impact pin connector 600 to lift the impact pin 200. This eliminates the need for complex tooth structures on the impact pin 200, which simplifies the design and manufacturing process of the impact pin 200 and reduces processing costs. On the other hand, it effectively improves the strength of the impact pin 200, making it less prone to deformation and damage during long-term use, thereby extending the service life of the impact pin 200.

[0052] In related technologies, the lifting structure of the firing pin 200 of a nail gun adopts a toothed meshing transmission method. Specifically, during the manufacturing of the firing pin 200, a series of spaced teeth are machined on its surface, and a matching lifting pin is configured on the lifting mechanism 900. When it is necessary to lift the firing pin 200, the lifting pin mechanically engages with the teeth of the firing pin 200, driving the lifting mechanism 900 to rotate via the drive motor 920. During this process, the lifting pin sequentially engages with multiple teeth on the firing pin 200, converting the rotational driving force into a linear lifting motion of the firing pin 200, thereby achieving the retraction operation of the firing pin 200.

[0053] The nail gun provided in this embodiment does not require a complex tooth structure on the firing pin 200. On the one hand, this simplifies the design and manufacturing process of the firing pin 200 and reduces processing costs. On the other hand, it effectively improves the strength of the firing pin 200, making it less prone to deformation and damage during long-term use, thereby extending the service life of the firing pin 200.

[0054] In optional embodiments, such as Figure 8 As shown, the lifting mechanism 900 may also include a rotating member 930, the lifting member 910 may be connected to the rotating member 930, and the firing pin connector 600 may be provided with a transmission column 610.

[0055] With the lifting member 910 in the first state, the lifting member 910 extends into the firing pin connector 600 and contacts the side of the transmission column 610 near the nozzle 110 of the gun body 100. The rotating member 930 can drive the lifting member 910 to rotate, thereby pushing the transmission column 610 to move from the firing position to the lifting position, so that the firing pin 200 moves from the firing position to the lifting position.

[0056] In this embodiment, the rotating member 930 converts the rotational motion into the linear motion of the transmission column 610 through the lifting member 910, thereby realizing the lifting of the firing pin 200. Furthermore, the design of the rotating member 930 can make the overall structure of the lifting mechanism 900 more compact, which is beneficial to reducing the size of the nail gun.

[0057] In other embodiments, the lifting mechanism 900 may not include the rotating member 930, and the lifting member 910 may move in the direction from the firing position to the lifting position to drive the firing pin connector 600 to move.

[0058] In an optional embodiment, the lifting mechanism 900 may include at least two lifting members 910, each of which can be connected to the rotating member 930 and can be distributed circumferentially along the rotating member 930. The firing pin connector 600 may be provided with at least two transmission posts 610, which can be spaced apart along the direction from the firing position to the lifting position. Each transmission post 610 can be disposed opposite to each lifting member 910, and each lifting member 910 can alternately contact the corresponding transmission post 610. In this embodiment, when each lifting member 910 alternately contacts the corresponding transmission post 610 in sequence, a relay-like manner can be formed to push the corresponding transmission post 610. Each lifting member 910 plays a role in a specific stage, pushing the firing pin 200 to move a certain distance. Subsequent lifting members 910 then continue to push the firing pin 200 based on the previous lifting member 910, thereby increasing the lifting stroke of the lifting mechanism 900 and ensuring that the firing pin 200 can move to the required lifting position. Furthermore, by having each lifting component 910 cooperate with its corresponding transmission column 610, the internal space of the nail gun can be fully utilized, providing a longer movement path for the firing pin 200.

[0059] Of course, the lifting mechanism 900 may also include only one lifting component 910, and the striker connector 600 may also be provided with only one transmission column 610.

[0060] Optionally, in the circumferential direction of the rotating member 930, the angle between the line connecting the edge of the lifting member 910 located on both sides away from the rotating member 930 and the center line of the rotating member 930 can be less than 180°. This arrangement allows each lifting member 910 to be distributed on one side of the rotating member 930, thereby enabling each lifting member 910 to switch to the second state. This ensures that each lifting member 910 does not interfere with the firing pin connector 600 and does not affect the movement of the firing pin connector 600 along the direction from the lifting position to the firing position, thus preventing interference with the firing of the firing pin 200.

[0061] Of course, in the circumferential direction of the rotating member 930, the angle between the edge of the lifting member 910 located on both sides away from the rotating member 930 and the line connecting the center line of the rotating member 930 can also be greater than or equal to 180°.

[0062] In some embodiments, each lifting member 910 may be distributed along the axial direction of the rotating member 930. This arrangement allows each lifting member 910 to make full use of the space of the nail gun in the axial direction of the rotating member 930, and avoids interference between the lifting members 910 and other components.

[0063] In this embodiment, the lifting mechanism 900 may include two lifting members 910, which may be a first lifting member 9101 and a second lifting member 9102, respectively. The firing pin connector 600 may be provided with two transmission pins 610, which may be a first transmission pin 611 and a second transmission pin 612, respectively. The first transmission pin 611 and the second transmission pin 612 may be spaced apart along the direction from the lifting position to the firing position.

[0064] During the process of raising the firing pin 200, the rotating component 930 first drives the first lifting component 9101 to move as follows. Figure 18 Rotate to the state shown as Figure 19 The state shown allows the first lifting member 9101 to extend into the firing pin connector 600 and contact the first transmission column 611. As the rotating member 930 rotates, as... Figure 20 As shown, the first lifting member 9101 continues to contact the first transmission column 611 and pushes the firing pin connector 600 to move a certain distance in the direction from the firing position to the lifting position. Then, the rotating member 930 continues to rotate, as... Figure 21 As shown, the second lifting member 9102 extends into the firing pin connector 600 and contacts the second transmission column 612; as the rotating member 930 continues to rotate, as... Figure 22 As shown, the first lifting member 9101 separates from the first transmission column 611, while the second lifting member 9102 continues to maintain contact with the second transmission column 612 and pushes the striker connector 600 to continue moving a certain distance until the edge of the second lifting member 9102 away from the rotating member 930 contacts the second transmission column 612. At this time, the striker 200 moves to the lifting position.

[0065] In optional embodiments, such as Figure 17 As shown, the lifting member 910 may include a rotating connecting part 912 and a lifting part 911. The rotating connecting part 912 may be connected to the rotating member 930, and the lifting part 911 may be connected to the rotating connecting part 912. The lifting part 911 has a lifting surface 9111. When the lifting member 910 is in the first state, the lifting part 911 extends into the firing pin connector 600, and the lifting surface 9111 contacts the transmission column 610.

[0066] Among them, such as Figure 17 As shown, the lifting surface 9111 can be an arc-shaped surface, which can protrude along the rotation direction of the rotating member 930. Furthermore, in the direction from the rotating connection 912 to the lifting part 911, the width of the lifting part 911 in the circumferential direction of the rotating member 930 gradually decreases.

[0067] This design ensures that the force transmission when the lifting surface 9111 contacts the transmission column 610 is a gradual process. As the lifting member 910 rotates, the contact point between the arc-shaped surface and the transmission column 610 gradually changes, allowing the thrust on the transmission column 610 to increase smoothly. This helps reduce mechanical impact and vibration, making the lifting process of the striker 200 more stable and reliable. Furthermore, the arc shape of the lifting surface 9111 allows the transmission column 610 to slide smoothly along the lifting surface 9111 during movement, reducing jamming caused by uneven contact surfaces or sudden angle changes. Since the lifting surface 9111 protrudes along the rotation direction of the rotating member 930, it is less likely to jam with the transmission column 610, making separation easier and preventing the lifting member 910 from getting stuck with the transmission column 610. Meanwhile, the width of the lifting part 911 in the circumferential direction of the rotating member 930 gradually decreases in the direction from the rotating part to the lifting part 911, which can reduce the space occupied by the lifting member 910 and prevent the lifting member 910 from interfering with other components and being unable to rotate.

[0068] In other embodiments, the lifting surface 9111 may not be an arc-shaped surface; for example, the lifting surface 9111 may be a plane.

[0069] In optional embodiments, such as Figure 17 As shown, a groove 914 can be provided between the rotating connecting part 912 and the lifting part 911. The groove 914 can be located close to the lifting surface 9111, and the concave direction of the groove 914 is opposite to the convex direction of the lifting surface 9111. In this embodiment, the groove 914 can change the stress distribution state of the lifting member 910, making the stress more evenly distributed on the lifting member 910. The groove 914 can guide the stress to be dispersed around the groove 914, avoiding stress concentration in the local area where the lifting surface 9111 contacts the transmission column 610, thereby reducing the risk of fatigue cracks and fractures in the lifting member 910 caused by stress concentration, and helping to extend the service life of the lifting member 910.

[0070] Of course, the groove 914 may not be provided between the rotating connecting part 912 and the lifting part 911.

[0071] Optionally, the lifting member 910 may be provided with weight reduction holes 913 to reduce the weight of the lifting member 910.

[0072] In some embodiments, the lifting mechanism 900 may further include a drive motor 920, which may be connected to the rotating member 930 and used to drive the rotating member 930 to rotate, thereby driving the lifting member 910 to rotate.
