Technical Field
[0001] This application relates to the field of power tools, and more specifically to a fastener driver. Background Technology
[0002] One type of fastener driver in related technologies is commonly used to secure workpieces. Users fire fasteners into the workpiece to achieve fixation. Typically, users need to install multiple fasteners in the fastener driver's magazine for continuous use. However, existing fastener drivers often experience poor fit between the fastener and the firing pin when only a small number of fasteners remain in the magazine, negatively impacting the user experience.
[0003] This section provides background information related to this application, which is not necessarily prior art. Summary of the Invention

[0023] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.
[0024] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0025] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, "a and / or b" can represent three cases: a alone, both a and b, and b alone.

[0027] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values that do not use relative terms should also be disclosed as specific values with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.
[0028] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.
[0029] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation.

[0032] In this application, the terms “calculation,” “judgment,” “control,” “determine,” “identify,” etc., refer to the operation and process of a computer system or similar electronic computing device (e.g., controller, processor, etc.).
[0033] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.
[0034] This embodiment provides a fastener driver 100. For example... Figure 1 and Figure 2 As shown, the fastener driver 100 provided in this embodiment is a pre-charged single-cylinder fastener driver. The fastener driver can be a single-cylinder fastener driver, a double-cylinder fastener driver, a pre-charged fastener driver, a non-pre-charged fastener driver, a spring-loaded fastener driver, etc., and is not limited here. The fastener driver 100 can generate an impact force on the fastener 10, thereby driving the fastener 10 into the workpiece. The fastener driver 100 includes a housing 110 and a magazine 120. The housing 110 includes a main housing 111, a transmission part 112, and a grip part 113 for the user to hold. The magazine 120 is used to hold the fastener 10, and at least a portion of the magazine 120 is disposed on the outside of the housing 110. The fastener 10 provided in this embodiment is a nail. The size of the nail can be 15Ga, 16Ga, 18Ga, 23Ga, 25Ga, etc., and is not limited here. The angle at which nails can be used can be 0 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, etc., and there is no limitation here. Nails can be straight nails, U-shaped nails, etc., and there is no limitation here.
[0035] One end of the grip 113 is connected to the main housing 111. A trigger 1131 is provided on the grip 113, and the trigger 1131 is connected to the main switch. The user triggers the main switch via the trigger 1131 to control the start and stop of the fastener driver 100. The main switch can be a mechanical or electronic switch. The fastener driver 100 includes a connecting portion 114. The other end of the grip 113 is connected to the connecting portion 114, which is used to connect to a DC or AC power source. In this embodiment, the battery pack 115 is detachably mounted on the connecting portion 114; the specifications and power of the battery pack 115 are not limited here.
[0036] like Figures 2 to 3 As shown, the fastener driver 100 also includes a striking assembly 130, a transmission mechanism 140, an energy storage device 150, and a motor 160. The striking assembly 130 includes a striking pin 131 and a piston 132. The striking pin 131 is mounted on the piston 132, which is substantially located behind the striking pin 131. The energy storage device 150 drives the piston 132 and the striking pin 131 forward to output a striking force in the striking direction. The striking pin 131 strikes the fastener 10 to drive it into the workpiece. The transmission mechanism 140 drives the striking pin 131 backward to store energy in the energy storage device 150. The energy storage device 150 includes a first cylinder 151. The first cylinder 151 houses the piston 132 and allows the piston 132 and a portion of the striking pin 131 to reciprocate within the first cylinder. A receiving space is formed inside the main housing 111 to accommodate at least a portion of the energy storage device 150 and the striking assembly 130. The main housing 111 supports at least a portion of the energy storage device 150. The motor 160 drives at least the transmission mechanism 140, and the battery pack 115 provides energy to the motor 160. A receiving space is formed inside the transmission section 112. At least a portion of the motor 160 and the transmission mechanism 140 are housed within the transmission section 112. The transmission section 112 supports at least a portion of the motor 160 and the transmission mechanism 140. In this embodiment, the motor 160 is an electric motor. When the transmission mechanism 140 drives the striking assembly 130 to move backward, the air in the first cylinder 151 is compressed, and the energy storage device 150 stores energy. When the energy storage device 150 drives the striking assembly 130 to move forward, the elastic potential energy of the compressed air is converted into kinetic potential energy, and the striking assembly 130 outputs a striking force.
[0037] like Figures 3 to 7As shown, the fastener driver 100 includes a trigger assembly 200. The trigger assembly 200 is user-operable. At least a portion of the trigger assembly 200 is configured to move along a first straight line 101. The trigger assembly 200 has a first state and a second state. In the first state, the trigger assembly 200 allows the striker 131 to strike the fastener 10. In the second state, the trigger assembly 200 prevents the striker 131 from striking the fastener 10. The user operates the trigger assembly 200 to switch between the first and second states. Generally, the user presses at least a portion of the trigger assembly 200 against a workpiece to activate the at least a portion of the trigger assembly 200. The trigger assembly 200 includes a trigger lever 201 and a contact 202. The contact 202 is at least partially located at the foremost end of the fastener driver 100, so that when the user aligns the foremost end of the fastener driver 100 with and approaches the workpiece, the contact 202 will first contact the workpiece. As the contact 202 contacts the workpiece and moves, the trigger lever 201 moves with the contact 202. At least a portion of the trigger lever 201 and the contact element 202 are configured to move along a first straight line 101. It should be noted that the trigger lever 201 and the contact element 202 move relative to the housing 110 along the first straight line 101. After the contact element 202 contacts the workpiece, if the user continues to operate the fastener driver 100 toward the workpiece, the positions of the trigger lever 201 and the contact element 202 relative to the workpiece remain unchanged, but the housing 110 moves toward the workpiece. Therefore, the trigger lever 201 and the contact element 202 move backward relative to the housing 110 along the first straight line 101. Similarly, while the contact element 202 remains in contact with the workpiece, if the user operates the fastener driver 100 away from the workpiece, the positions of the trigger lever 201 and the contact element 202 relative to the workpiece remain unchanged, but the housing 110 moves away from the workpiece. Therefore, the trigger lever 201 and the contact element 202 move forward relative to the housing 110 along the first straight line 101. The trigger rod 201 and the contact member 202 are connected by threads, so that the contact member 202 can drive the trigger rod 201 to move along the first straight line 101, and the trigger rod 201 can also move relative to the contact member 202.
[0038] The fastener driver 100 includes a safety switch. The user can only use the fastener driver 100 to remove the fastener 10 when both the safety switch and the main switch are triggered. The trigger assembly 200 is configured to trigger the safety switch. The safety switch is triggered when the trigger assembly 200 moves to the trigger position. The safety switch can be a mechanical or electronic switch.
[0039] When the trigger assembly 200 is not against the workpiece, or when the trigger assembly 200 is against the workpiece but has not moved to the trigger position, the trigger assembly 200 is in the second state. When the trigger assembly 200 is against the workpiece and moves backward along the first straight line 101 to the trigger position, the safety switch is triggered, and the trigger assembly 200 is in the first state. When the safety switch is open and the user presses the trigger 1131, the firing pin 131 strikes out a fastener 10. After striking, the firing pin 131 remains in the stop position, waiting for the user to press the trigger 1131 again and the safety switch to open to strike the next fastener 10. In the stop position, the fastener driver 100 stops. When the user presses the trigger 1131, the drive mechanism continues to drive the firing pin 131 to move backward to the top dead center position. The air in the first cylinder 151 is substantially compressed to its limit, and the elastic potential energy stored in the energy storage device 150 is substantially at its peak. The striking assembly 130 stops moving backward, and the firing pin 131 moves substantially to its furthest possible position. In some embodiments, when the trigger 1131 is pressed, the firing pin 131 strikes the fastener 10 once each time the safety switch is activated, that is, each time the user presses the fastener driver 100 against the workpiece. After the firing pin 131 completes one strike, the fastener 10 moves in the magazine 120 so that the firing pin 131 can strike the next fastener 10. The striking assembly 130 reciprocates under the drive of the transmission mechanism 140 and the energy storage device 150 to continuously strike the fasteners 10 sequentially. In each striking cycle, the fastener driver 100 fires one fastener 10.
[0040] The fastener driver 100 includes a guide assembly 180 that guides the fastener 10 to move in the direction of impact. The guide assembly 180 communicates with at least a portion of the magazine 120. The fastener driver 100 also includes a support frame 190. The support frame 190 connects the energy storage device 150 and the guide assembly 180. The support frame 190 includes a hole 191 through which the firing pin 131 passes. The support frame 190 is fixedly connected to the energy storage device 150, and the guide assembly 180 is fixedly connected to the support frame 190. The support frame 190 simultaneously fixes the energy storage device 150 and the guide assembly 180 such that the energy storage device 150 and the guide assembly 180 have high coaxiality. The guide assembly 180 includes a first guide 181 and a second guide 182. The second guide 182 includes an inlet 1821. The inlet 1821 communicates with at least a portion of the magazine 120 such that the fastener 10 is lifted from the magazine 120 through the inlet 1821 to the guide assembly 180.
[0041] like Figures 6 to 7As shown, the guide assembly 180 includes a first mounting portion 183 for mounting the trigger rod 201. The first mounting portion 183 includes a first protrusion 1831 formed on the second guide member 182. The first protrusion 1831 has a through hole, allowing it to be sleeved onto the trigger rod 201. The trigger rod 201 is supported by the first mounting portion 183. When the contact member 202 moves, the contact member 202 drives the trigger rod 201 to move along a first straight line 101 through the first mounting portion 183. The trigger rod 201 is supported by the first mounting portion 183, saving manufacturing costs and providing structural stability. The support frame 190 includes a second mounting portion 192 for mounting the detection mechanism 170. The detection mechanism 170 is used to detect the position of the trigger assembly 200. The second mounting portion 192 includes a second protrusion 1921 formed on the support frame 190. The testing mechanism 170 is fixedly mounted to the second protrusion 1921 with screws.
[0042] A detection mechanism 170 is mounted on a support frame 190. The support frame 190 and a guide assembly 180 are fixedly connected, and the guide assembly 180 supports the trigger assembly 200. Thus, both the guide assembly 180 and the detection mechanism 170 are mounted on the support frame 190, and the positional relationship between the detection mechanism 170 and the guide assembly 180 is fixed. The guide assembly 180 supports the trigger assembly 200, ensuring a stable and reliable positional relationship between the trigger assembly 200 and the detection mechanism 170. This facilitates accurate identification of the trigger assembly 200's position by the detection mechanism 170, reducing errors.
[0043] like Figures 3 to 4 , Figures 7 to 8 As shown, the trigger assembly 200 includes a sleeve 210, which has a hole. The sleeve 210 is fitted onto the end of the trigger rod 201 near the detection structure through the hole. In this embodiment, the sleeve 210 and the trigger rod 201 are detachably connected by threads, which facilitates installation and results in a simple and compact structure. After the sleeve 210 is fixedly installed onto the trigger rod 201, the sleeve 210 moves synchronously with the trigger rod 201. In some embodiments, the sleeve 210 can also be connected to the trigger rod 201 in other ways, or the sleeve 210 can be integrally formed with the trigger rod 201. The trigger assembly 200 includes a receiving chamber 212, which accommodates at least a portion of the sensing device 175. The receiving chamber 212 is disposed on the sleeve 210. In this embodiment, the receiving chamber 212 is a cylindrical empty chamber formed at the center of the sleeve 210. The receiving chamber 212 can be open or closed, which is not limited here.
[0044] The sensing device 175 causes the triggering component 200 to switch between a first state and a second state. The fastener driver 100 includes a control device 220, which includes a controller 221. The controller 221 is configured to connect to the detection mechanism 170. The controller 221 is connected to the detection mechanism 170 so that signals can be sent and received between the controller 221 and the detection mechanism 170. The detection mechanism 170 is configured to sense the position of the sensing device 175. When the sensing device 175 moves with the triggering component 200 to the trigger position, the detection mechanism 170 detects the sensing device 175 and controls the safety switch to turn on via the controller 221, placing the triggering component 200 in the first state. When the sensing device 175 moves away from the trigger position with the triggering component 200, the detection mechanism 170 detects that the sensing device 175 is not in the trigger position and controls the safety switch to turn off via the controller 221, placing the triggering component 200 in the second state. The sensing device 175 includes a magnetic element 176, specifically a cylindrical magnet. The detection mechanism 170 includes a Hall sensor 171. The magnet is directly fixed to the trigger rod 201 by being installed in the sleeve 210. The magnet moves with the sleeve 210 and the trigger rod 201, making installation simple, the structure stable and compact, and the detection accuracy high. In some embodiments, the detection mechanism 170 may also include a potentiometer, and the sensing device 175 may also include other parts that can be detected by the detection mechanism 170. There are no limitations here, as long as the detection mechanism 170 can detect the position of the sensing device 175.
[0045] The trigger assembly 200 includes a depth adjustment member 213 and a shim 214. The user rotates the depth adjustment member 213 to adjust the depth to which the fastener 10 is driven into the workpiece. The depth adjustment member 213 and the trigger rod 201 are driven together; when the depth adjustment member 213 rotates, it drives the trigger rod 201 and the sleeve 210 to rotate as well. The shim 214 is positioned between the sleeve 210 and the first mounting portion 183 to prevent direct contact between the moving sleeve 210 and the stationary first mounting portion 183, thereby preventing the sleeve 210 from loosening due to friction. The shim 214 is fixedly fitted onto the trigger rod 201 via a flat sleeve, allowing the shim 214 to move synchronously with the trigger rod 201. The synchronous movement of the sleeve 210, the shim 214, and the trigger rod 201 reduces friction, preventing loosening between parts and ensuring a stable and reliable connection.
[0046] like Figures 1 to 4As shown, the housing 110 includes an extension 1121, which accommodates a first mounting portion 183, a portion of a trigger rod 201, a rod sleeve 210, a sensing device 175, and a detection mechanism 170. The portion of the trigger rod 201, rod sleeve 210, and sensing device 175 can move within the extension 1121. The extension 1121 prevents dust from contaminating the parts, has a simple and reliable structure, saves costs, and is aesthetically pleasing. In this embodiment, the extension 1121 is integrally formed with the transmission portion 112, resulting in low manufacturing costs. In some embodiments, the extension 1121 is integrally formed with the main housing 111.
[0047] The distance L1 between the end of the trigger rod 201 furthest from the detection mechanism 170 and the foremost point of the fastener driver 100 is greater than or equal to 30 mm and less than or equal to 60 mm. In some embodiments, L1 is greater than or equal to 35 mm and less than or equal to 55 mm. In some embodiments, L1 is greater than or equal to 40 mm and less than or equal to 50 mm. The foremost point of the fastener driver 100 is unobstructed, providing good visibility and facilitating the user to insert the guide assembly 180 into confined spaces for operation.
[0048] like Figure 6 As shown, the guide assembly 180 includes a stop 184. The stop 184 prevents the workpiece from contacting the trigger rod 201 before the contact member 202 when the user is working on an irregular workpiece using the fastener driver 100, thus avoiding a safety hazard. The stop 184 is located above the trigger rod 201. In some embodiments, the stop 184 may also be located below the trigger rod 201. In the front-rear direction, the foremost point of the stop 184 is substantially level with the foremost point of the trigger rod 201. The position of the stop 184 is fixed relative to the housing 110, so that when the workpiece contacts the stop 184, the workpiece is blocked by the stop 184, and the workpiece will not continue to cause movement of the trigger rod 201, thus preventing the safety switch from being triggered, thereby improving safety. The distance between the end of the stop 184 away from the detection mechanism 170 and the foremost point of the fastener driver 100 is substantially equal to L1, ensuring good visibility of the foremost point of the fastener driver 100. The stop 184 is disposed on the second guide member 182, resulting in a compact structure. In this embodiment, the stop 184 and the second guide 182 are integrally formed, saving costs.
[0049] After a single strike, the firing pin 131 remains in the stopped position. The fastener driver 100 includes a lifting assembly 230. At least a portion of the lifting assembly 230 is movably disposed within the magazine 120 to move the fastener 10 within the magazine 120. After a fastener 10 is fired, the lifting assembly 230 lifts the next fastener 10 through the input port 1821 to the guide assembly 180 for being fired by the firing pin 131. During the time difference between the firing pin 131 reaching the stopped position and the fastener driver 100 firing the next fastener 10, the lifting assembly 230 needs to lift a fastener 10 from the magazine 120 to the front of the firing pin 131. If the lifting assembly 230 jams, the fastener 10 may not be lifted to a position where it can be fired by the firing pin 131, resulting in the firing pin 131 continuing to move but failing to fire the fastener 10, which is inconvenient and reduces work efficiency.
[0050] Normally, in order to quickly eject the fastener 10 on the next strike, the firing pin 131 and piston 132 are in a state of compressing the air in the first cylinder 151 when the machine is in the stopped position. If the fastener driver 100 vibrates or encounters other situations, the firing pin 131 may accidentally disengage and eject the fastener 10 without the user's knowledge, causing a hazard.
[0051] In some embodiments, in the stop position, the tip of the firing pin 131 is located behind the fastener 10, and the firing pin 131 and the fastener 10 do not overlap in the front-to-back direction. The fastener driver 100 includes means to prevent the firing pin 131 from being accidentally ejected. In these embodiments, the time difference between the firing pin 131 reaching the stop position and the fastener driver 100 next ejecting the fastener 10 depends on the speed at which the user operates the fastener driver 100. After the user ejects a fastener 10, the firing pin 131 moves to the stop position. Subsequently, the user lifts the fastener driver 100, moves the fastener driver 100 to the appropriate position, and ejects another fastener 10. The time difference between the firing pin 131 reaching the stop position and the fastener driver 100 next ejecting the fastener 10 is substantially equal to the time consumed by the user lifting, moving, and then pressing down the fastener driver 100. Understandably, the average time consumed by the user to lift, move, and then press down the fastener driver 100 is generally greater than 1 second. That is to say, since the striker 131 and the input port 1821 do not interfere with each other, after the striker 131 moves to the stop position, the lifting assembly 230 can start lifting the fastener 10, and the lifting assembly 230 must lift the fastener 10 to the guide assembly 180 within a time of more than 1 second.
[0052] In this embodiment, as Figure 7As shown, in the stop position, the firing pin 131 presses against the fastener 10, and the firing pin 131 and the fastener 10 overlap in the front-to-back direction. The firing pin 131 interferes with the input port 1821 in the stop position. Thus, even if the firing pin 131 is accidentally ejected after stopping in the stop position, the fastener 10 will not be ejected. In this embodiment, the time difference between the firing pin 131 reaching the stop position and the fastener driver 100 ejecting the fastener 10 next depends on the speed at which the firing pin 131 moves and the distance between the stop position and the top dead center position. After the user ejects a fastener 10, the firing pin 131 quickly moves to the stop position. Because the firing pin 131 interferes with the input port 1821 in the stop position, during the process of the user lifting, moving, and then pressing down the fastener driver 100, the firing pin 131 remains in the stop position, preventing the lifting assembly 230 from lifting the fastener 10 to the guide assembly 180. When the user presses trigger 1131 again, the firing pin 131 moves to the upper dead center position, which means the firing pin 131 moves backward. Only when the firing pin 131 moves to a position where it no longer interferes with the input port 1821 can the lifting assembly 230 begin to lift the fastener 10 to the guide assembly 180. This lifting action must end before the firing pin 131 moves forward from the upper dead center position to contact the fastener 10, i.e., before reaching the striking position. The time difference between the firing pin 131 reaching the stop position and the fastener driver 100 firing the fastener 10 again is approximately equal to the time it takes for the firing pin 131 to move from the stop position to the upper dead center position and then to the striking position. The time taken for the firing pin 131 to move from the stop position to the upper dead center position and then to the striking position is generally much less than 1 second. In this embodiment, the time taken for the firing pin 131 to move from the stop position to the upper dead center position and then to the striking position is approximately 0.02 to 0.04 seconds. In other words, the lifting component 230 needs to lift the fastener 10 to the guide component 180 within a time of approximately 0.02 to 0.04 seconds. In order for the lifting component 230 to lift the fastener 10 into place in a short period of time, the lifting component 230 needs to move smoothly and without jamming.
[0053] like Figures 9 to 13As shown, the fastener driver 100 includes an anti-dry-fire component 240, which has an anti-dry-fire state. The anti-dry-fire component 240 includes a stop 241. The anti-dry-fire component 240 is in the anti-dry-fire state when the stop 241 is on the movement path of the trigger component 200. The trigger component 200 is in a first state when it is on the movement path of the stop 241. In the anti-dry-fire state, the stop 241 prevents the trigger component 200 from switching to the first state, and the trigger component 200 can only remain in the second state. Thus, in the anti-dry-fire state, the user cannot use the fastener driver 100 to fire the fastener 10. When the remaining quantity of fasteners 10 reaches a low preset value, the anti-dry-fire component 240 switches to the anti-dry-fire state. The function of the anti-dry-fire state is that, in the anti-dry-fire state, the user can be informed that the quantity of fasteners 10 is insufficient, and thus replenish the fasteners 10 in the magazine 120 in a timely manner. The minimum preset value is defined as the remaining number of fasteners 10 under anti-aircraft attack conditions. In some embodiments, the minimum preset value is 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 fasteners.
[0054] Before entering the anti-aircraft firing state, a certain number of fasteners 10 remain in the magazine 120. Understandably, before entering the anti-aircraft firing state, the number of fasteners 10 remaining in the magazine 120 is greater than or equal to a minimum preset value. The closer to the anti-aircraft firing state, the fewer fasteners 10 remain in the magazine 120, and the closer the number of fasteners 10 gets to the minimum preset value. First State The lifting assembly 230 is movably mounted on the magazine 120. In this embodiment, the lifting assembly 230 moves up and down relative to the magazine 120 under user operation. The lifting assembly 230 includes a magazine elastic member that biases the lifting assembly 230 toward the guide assembly 180. The user overcomes the elastic force and operates the lifting assembly 230 away from the guide assembly 180 to make room for the fasteners 10. When the fasteners 10 are full, the lifting assembly 230 is furthest from the guide assembly 180, and when the fasteners 10 are depleted, the lifting assembly 230 is closest to the guide assembly 180. Each time the firing pin 131 fires a fastener 10, the space above the remaining fasteners 10 becomes available. If the input port 1821 is unobstructed, the lifting assembly 230, driven by the magazine elastic member, lifts the fasteners 10 in the magazine 120 upwards to add a fastener 10 to the front end of the firing pin 131. The magazine's elastic element is a spring, which can be a tension spring or a coil spring.
[0055] The lifting assembly 230 drives the stop 241 and the fastener 10 to move. The lifting assembly 230 includes a first lifting part 232 and a second lifting part 233. The first lifting part 232 is configured to drive the stop 241 to move, and the second lifting part 233 is configured to drive the fastener 10 to move. After the fastener 10 is inserted into the magazine 120, the second lifting part 233 abuts against the lower end of the fastener 10, and the second lifting part 233 drives the fastener 10 to move upward. The stop 241 is located at one end of the magazine 120 near the guide assembly 180, and the stop 241 includes a first abutment surface 2421.
[0056] As the fastener 10 is gradually consumed, the lifting assembly 230 moves upward and gradually approaches the guide assembly 180. After the first lifting portion 232 and the first abutment surface 2421 abut, the lifting assembly 230 and the stop member 241 form a driving connection. When the lifting assembly 230 continues to move upward, the lifting assembly 230 begins to drive the stop member 241 to perform a first motion. The stop member 241 is configured to rotate about the first axis 1001. The first motion is a first movement of rotating about the first axis 1001 in the first direction 1010. The relative positions of the first lifting portion 232 and the second lifting portion 233 are fixed. When the first lifting portion 232 drives the stop member 241 to perform the first motion, the second lifting portion 233 simultaneously drives the fastener 10 to move upward. In this embodiment, the first lifting portion 232 has an inclined surface, and the second lifting portion 233 has an arc surface.
[0057] In the left-right direction, at least a portion of the stop 241 is disposed between the magazine 120 and the trigger assembly 200. In the front-back direction, at least a portion of the stop assembly is disposed between the trigger assembly 200 and the detection mechanism 170. The stop 241 includes a stop portion 243 and a rotating portion 244. The stop portion 243 is located away from the first axis 1001 relative to the rotating portion 244. During a first movement, the stop 241 rotates about the first axis 1001 along a first direction 1010, and the stop portion 243 moves toward the trigger assembly 200. The trigger assembly 200 includes a trigger portion 216 extending perpendicular to the first straight line 101. Viewed along the first straight line 101, when the stop portion 243 and the trigger portion 216 begin to overlap, the stop portion 243 is located on the movement path of the trigger portion 216. The stop portion 243 prevents the lever sleeve 210 and the trigger rod 201 from moving toward the detection mechanism 170 along the first straight line 101. The stop 243 prevents the sensing device 175 from moving to a position detectable by the detection mechanism 170, i.e., the trigger position. The safety switch cannot be triggered, and the anti-dry-fire assembly 240 is in the anti-dry-fire state. The fastener driver 100 reminds the user to replenish the fastener 10. In other words, when observing the fastener driver 100 in the front-back direction, when the stop 241 and the sleeve 210 begin to overlap, the stop 241 prevents the sleeve 210 from moving backward, the anti-dry-fire assembly 240 is in the anti-dry-fire state, and the trigger component 200 can only remain in the second state. Conversely, when observing the fastener driver 100 in the left-right direction, when the stop 241 and the sleeve 210 begin to overlap, the trigger component 200 enters the first state, and the sleeve 210 prevents the stop 241 from moving to the right, preventing the anti-dry-fire assembly 240 from switching to the anti-dry-fire state.
[0058] Each time fastener 10 is ejected, lifting assembly 230 lifts upward once. The distance the lifting assembly 230 moves upward each time depends on the thickness of each fastener 10 in the vertical direction. Since the thickness of fastener 10 is generally small, the lifting distance of the lifting assembly 230 each time is short. When the first lifting part 232 abuts against the first contact surface 2421, and the first lifting part 232 moves upward, the first lifting part 232 drives the stop member 241 to perform a first movement. The upward movement of the first lifting part 232 drives the rotation of the stop member 241. Because the upward movement distance of the first lifting part 232 each time is very short, the angle of rotation of the stop part 243 toward the trigger assembly 200 each time is also very small.
[0059] When a preset number of fasteners 10 remain in the magazine, the trigger assembly 200 will prevent the stop member 241 from performing a first movement. While the trigger assembly 200 prevents the stop member 241 from performing the first movement, the lifting assembly 230 drives the stop member 241 to perform a second movement. When the trigger assembly 200 is in the first state and prevents the stop member 241 from performing the first movement, the trigger assembly 200 prevents the stop member 241 from switching to an anti-dry-fire state, therefore the lifting assembly 230 drives the stop member 241 to perform the second movement. The trigger assembly 200 includes a blocking portion 215 located in the circumferential direction of the first straight line 101. When the blocking portion 215 is on the movement path of the stop member 243 performing the first movement, the blocking portion 215 prevents the stop member 241 from performing the first movement. In this embodiment, the sleeve 210 includes the blocking portion 215, which is the outer circumferential surface of the sleeve 210. Before the anti-aircraft fire assembly 240 enters the anti-aircraft fire state, the trigger assembly 200 can move normally along the first straight line 101. When the trigger assembly 200 moves to the trigger position, a fastener 10 is fired. The firing pin 131 then quickly moves to the stop position, and the firing pin 131 overlaps with the input port 1821 in the stop position. Therefore, until the next time the trigger assembly 200 moves to the trigger position, the firing pin 131 moves back to not overlap with the input port 1821, and the firing pin 131 prevents the lifting assembly 230 from lifting the fastener 10. When the number of fasteners 10 is less than the preset number, the lifting assembly 230 only abuts against the fasteners 10. As the fasteners 10 are gradually consumed, and the number of remaining fasteners 10 in the magazine 120 approaches the preset number, the lifting assembly 230 moves to abut against the stop member 241. When the user operates the trigger component 200, the trigger component 200 moves to the trigger position, the striker 131 moves back to not overlap with the input port 1821, the lifting component 230 drives the fastener 10 to move upward, and starts to drive the stop 241 to perform the first movement.
[0060] Trigger component 200 in Figures 14 to 17 In the first state, Figures 18 to 19 It is in the second state. For example... Figure 14 and Figure 15As shown, when the trigger assembly 200 is in the trigger position, when the fastener driver 100 is viewed from the left or right side, the obstruction portion 215 and the stop portion 243 at least partially overlap in the front-to-back direction. When the fastener driver 100 is viewed from the front or rear side, if the gap between the obstruction portion 215 and the stop portion 243 is very small in the left-to-right direction, or if the obstruction portion 215 is just in contact with the stop portion 243, the trigger assembly 200 obstructs the stop member 241 from performing a first movement. That is, when the number of fasteners 10 reaches a preset number, in the first state, the striker 131 moves, and then the lifting assembly 230 begins to drive the stop member 241 to perform a first movement, but the trigger assembly 200 obstructs the stop member 241 from performing a first movement. Since the lifting assembly 230 abuts against the stop member 241, if the stop member 241 cannot perform a first movement, the lifting assembly 230 cannot move upward. The lifting assembly 230 is jammed, preventing the fastener 10 from being lifted to the input port 1821 for the firing pin 131 to strike. The stop 241 cannot make its first movement, thus the anti-dry-firing assembly 240 cannot enter the anti-dry-firing state. This means that every time the user operates the trigger assembly 200, the firing pin 131 will fire dry once. Especially in this embodiment, the firing pin 131 interferes with the input port 1821 in the stopped position. The lifting assembly 230 needs to lift the fastener 10 to the input port 1821 within a very short time. Even a slight jamming of the lifting assembly 230 will prevent it from properly lifting the fastener 10, and the user will be unable to use the fastener driver 100 normally.
[0061] like Figure 16 and Figure 17As shown, when the triggering component 200 obstructs the stop 241 from performing a first movement, the lifting component 230 drives the stop 241 to perform a second movement. The stop 241 is also configured to rotate about a second axis 1002. The second movement includes a first action of rotating about a first axis 1001 in a first direction 1010 and a second action of rotating about a second axis 1002 in a second direction 1020. When the obstructing part 215 abuts against the stop part 243, the first lifting part 232 and the first abutting surface 2421 abut against each other to drive the stop 241 to perform a second movement. The second movement includes the first action and the second action. The first action and the second action are rotational actions about different axes. When the stop 241 rotates about two different axes, the stop 241 rotates in two dimensions. The stop 241 has at least two rotational degrees of freedom. The first action and the second action occur substantially synchronously, and combining the first action and the second action, it can be understood that the stop 241 is flipping. Alternatively, the flipping of the stop 241, that is, the second movement of the stop 241, can be broken down into a first action and a second action, while the first movement of the stop 241 only includes the first action. Thus, when the trigger component 200 obstructs the stop 241 from performing the first movement, the stop 241 switches to performing the second movement to allow at least partial lifting of the lifting component 230. During the second movement of the stop 241, the lifting component 230 drives the fastener 10 to move. It should be understood that in this embodiment, the first axis 1001 is a fixed axis, but when the stop 241 rotates around the first axis 1001 at different angles, the position of the second axis 1002 will change with the position of the stop 241. As long as the second movement includes rotation around two different axes, the position of the axes is not limited here. In some embodiments, the second movement may also include rotation around more axes.
[0062] When the trigger component 200 obstructs the stop member 241 from making the first movement, the lifting component 230 can drive the stop member 241 to make the second movement, so that the lifting component 230 can normally lift the fastener 10. The reason is as follows.
[0063] The fastener actuator 100 includes an elastic element 250. When the lifting assembly 230 applies a first force F1 to the stop 241 and the obstruction portion 215 applies a second force F2 to the stop 241, the stop 241 applies a third force F3 to the elastic element 250 to perform a second movement. In other words, the compressive stress applied to the stop 243 by the first lifting portion 232 and the obstruction portion 215 is converted into elastic force through the elastic element 250. The force is transferred to the elastic element 250, which acts as a force relief element. During the force conversion, the stop 241 rotates about a second axis 1002 in a second direction 1020 to perform the second action. The second axis 1002 extends substantially along the length direction of the stop 241. When the stop 241 rotates about the second axis 1002, when viewed from the front-rear direction, the space occupied by the stop portion 243 in the left-right direction decreases, allowing the lifting assembly 230 to move upward. When the stop member 241 performs its second action, the first force F1 and the second force F2 gradually transform into a third force F3, and the deformation of the elastic member 250 gradually increases. As the stop member 241 performs its second action, the lifting assembly 230, driven by the magazine elastic member, also drives the stop member 241 to perform its first action. The lifting assembly 230 then moves smoothly upward to lift the fastener 10 via the second lifting part 233. The upward movement of the lifting assembly 230 and the second movement of the stop member 241 are complementary and synchronous; there is no sequential order between them.
[0064] like Figure 18 and Figure 19As shown, after the stop 241 performs its second movement, the elastic member 250 drives the stop 241 to perform a third movement. When the second force F2 decreases to zero, the elastic member 250 drives the stop 241 to perform a third movement. When the user lifts the fastener driver 100, the trigger assembly 200 moves forward to disengage from the first state and begins to enter the second state, the contact area between the obstruction part 215 and the stop part 243 gradually decreases. Since the second force F2 acting on the stop 241 decreases to zero, the force on the stop 241 is no longer balanced, the elastic member 250 begins to restore its original shape, the elastic potential energy stored in the elastic member 250 is converted into kinetic energy, and the elastic member 250 applies a reaction force F4 to the stop 241 to drive the stop 241 to perform a third movement. The third movement includes a third action of rotating about the second axis 1002 along a third direction 1030. The third action is opposite to the second action. The third movement also includes a first action of rotating about the first axis 1001 along a first direction 1010. After the stop 241 performs its third movement, viewed along the front-to-back direction, when the stop 243 and the trigger 216 overlap in the left-to-right direction, the stop 243 is located on the movement path of the trigger 216. The stop 243 blocks the movement of the trigger assembly 200, and the stop 241 prevents the trigger assembly 200 from switching to the first state, thus the anti-dry-firing assembly 240 enters the anti-dry-firing state. The fastener driver 100 is smooth and convenient to use.
[0065] like Figure 20 and Figure 21As shown, the anti-aircraft gun assembly 240 includes a limiting portion 245 and a rotating shaft 246. The limiting portion 245 restricts the range of the second movement of the stop member 241. The limiting portion 245 is disposed at one end of the magazine 120 near the guide assembly 180 and on the side near the trigger assembly 200. In this embodiment, the limiting portion 245 and the magazine 120 are integrally formed, saving costs. At least a portion of the rotating shaft 246 is mounted between the limiting portions 245. The limiting portion 245 includes a first limiting wall 2451 and a second limiting wall 2452, which are disposed opposite to each other in the front-rear direction. The first limiting wall 2451 and the second limiting wall 2452 each include a hole. The rotating shaft 246 passes through the holes of the first limiting wall 2451 and the second limiting wall 2452 to be mounted on the limiting portion 245. In some embodiments, the rotating shaft 246 may also be mounted on the limiting portion 245 in other ways. The rotating shaft 246 is fixed relative to the limiting portion 245. The rotating shaft 246 is substantially parallel to the first axis 1001. The stop member 241 includes a middle portion 247 and a rotating portion 244. The middle portion 247 connects the rotating portion 244 and the stop portion 243. The stop portion 243 is bent upward relative to the middle portion 247, and the rotating portion 244 is bent downward relative to the middle portion 247. The rotating portion 244 is closer to the rotating shaft 246 than the stop portion 243 and the middle portion 247. The rotating portion 244 is movably fitted onto the rotating shaft 246 and has a clearance fit with the rotating shaft 246 to allow for rotation. The limiting portion 245 includes a receiving space 248 located between the first limiting wall 2451 and the second limiting wall 2452. The receiving space 248 can be an open or closed space. At least a portion of the rotating portion 244 is received in the receiving space 248.
[0066] The length L2 of the accommodating space 248 in the front-rear direction limits the range of the second movement of the stop 241. The length L3 of the rotating part 244 in the front-rear direction is L3. In the front-rear direction, the ratio L2 / L3 of the length of the accommodating space 248 and the rotating part 244 is greater than or equal to 1.2. Since the ratio of the length of the accommodating space 248 and the rotating part 244 in the front-rear direction is greater than 1.2, the length of the accommodating space 248 is greater than the length of the rotating part 244. The limiting part 245 does not obstruct the rotation of the stop 241, and the stop 241 has sufficient space to perform the second movement. The stop 241 rotates at a large angle around the second axis 1002. When viewed from the front-rear direction, the space occupied by the stop part 243 in the left-right direction can be reduced significantly, and the lifting assembly 230 can move upward a longer distance.
[0067] In some embodiments, the ratio of the length of the receiving space 248 to the length of the rotating part 244 is greater than or equal to 1.2 and less than or equal to 3. In some embodiments, the ratio of the length of the receiving space 248 to the length of the rotating part 244 is greater than or equal to 1.4 and less than or equal to 2.8. In this way, the receiving space 248 provides sufficient space for the stop member 241 to perform the second action, while preventing the stop member 241 from rotating too much, resulting in a simple structure and low cost.
[0068] like Figures 21 to 23 As shown, an elastic element 250 is disposed on a rotating shaft 246. The elastic element 250 includes a deformable portion 251. When the elastic element 250 is compressed, the deformable portion 251 deforms first. When the elastic element 250 returns to its original shape, the deformable portion 251 first drives the stop member 241 to move. The stop member 241 includes a second abutment surface 2422. The deformable portion 251 abuts against the second abutment surface 2422 to drive the stop member 241 to perform a third movement. At least a portion of the second abutment surface 2422 is located on the side of the rotating shaft 246 near the first lifting portion 232 and away from the stop portion 243. In this embodiment, the second abutment surface 2422 is located on the lower left side of the rotating shaft 246. In this way, the elastic element 250 can store or release energy during the first, second, and third movements of the stop member 241. The second abutment surface 2422 is a bent surface and is recessed toward the rotating shaft 246. The second abutment surface 2422 includes a groove. The deformable part 251 abuts against the groove.
[0069] The elastic element 250 is a spring wire, which is partially wound around the rotating shaft 246. The deformable portion 251 includes a first deformable portion 2511 and a second deformable portion 2512, which are the two ends of the spring wire, respectively. The first deformable portion 2511 extends substantially along the second straight line 102. The rotating shaft 246 extends substantially along the third straight line 103. Viewed from above and below, the angle p between the second straight line 102 and the third straight line 103 is greater than 0 degrees and less than or equal to 100 degrees. In some embodiments, the angle p between the second straight line 102 and the third straight line 103 is greater than or equal to 10 degrees and less than or equal to 50 degrees. In some embodiments, the angle p between the second straight line 102 and the third straight line 103 is greater than or equal to 20 degrees and less than or equal to 40 degrees. The angle p between the second straight line 102 and the third straight line 103 is greater than 0 degrees and less than or equal to 100 degrees. In this way, the deformable part 251 can both receive the force of the stop member 241 and drive the stop member 241 to move. In some embodiments, the elastic member 250 can also be of other shapes or materials, as long as it can deform under the force of the stop member 241 and drive the stop member 241 to move when it returns to its shape. There is no limitation here.
[0070] The elastic element 250 has an elastic force. The ratio of the elastic force to the mass of the stop element 241 is greater than 1 N / g and less than or equal to 10 N / g. In some embodiments, the ratio of the elastic force to the mass of the stop element 241 is greater than 1 N / g and less than or equal to 9 N / g, 8 N / g, 7 N / g, 6 N / g, 5 N / g, 4 N / g, 3 N / g, or 2 N / g. When the ratio of the elastic force to the mass of the stop element 241 is greater than 1 N / g, the elastic element 250 can drive the stop element 241 to move. When the ratio of the elastic force to the mass of the stop element 241 is less than or equal to 10 N / g, the stop element 241 can drive the elastic element 250 to deform under the drive of the lifting assembly 230.
[0071] When a preset number of fasteners 10 remain in the magazine 120, the stop 241 flips to allow at least a partial lifting assembly 230 to lift. After the lifting assembly 230 is lifted, the elastic element 250 drives the stop 241 to flip, causing the anti-dry-fire assembly 240 to enter the anti-dry-fire state, reminding the user to replenish the fasteners 10. The fastener driver 100 is convenient, quick, and safe to use.
[0072] like Figures 24 to 29 As shown, the fastener driver 100 includes a receiving portion 260 and a light-emitting device 270. The receiving portion 260 houses at least a portion of the light-emitting device 270, which is used for illumination and / or indication. The light-emitting device 270 includes a connecting portion 271, which is at least partially movably received within the receiving portion 260. The connecting portion 271 is movable relative to the receiving portion 260, such that at least a portion of the light-emitting device 270 can move relative to the housing 110. A user can operate the light-emitting device 270 to move at least a portion of the light-emitting device 270, allowing the light-emitting device 270 to illuminate and indicate a wider range.
[0073] In some embodiments, the receiving portion 260 is disposed on the housing 110. The light-emitting device 270 is generally used to illuminate the firing area of the fastener 10. In this embodiment, the receiving portion 260 is partially disposed on the transmission portion 112 and partially disposed on the main housing 111. The connecting portion 271 is configured to slide along the extending direction of the receiving portion 260. The receiving portion 260 is disposed substantially parallel to the extending direction of the main housing 111. The transmission portion 112 is relatively close to the guide assembly 180, so that the light-emitting device 270 can illuminate the firing area of the fastener 10 more clearly. In some embodiments, the light-emitting device 270 may also be disposed on the main housing 111, the transmission portion 112, the grip portion 113, the connecting portion 114, or the magazine 120, or may be disposed in any combination of portions of the housing 110.
[0074] The connecting portion 271 includes a slider 272. The receiving portion 260 includes a track 261, which guides the slider 272 to move. Figures 24 to 26As shown, in this embodiment, the surface of the slider 272 is curved. The slider 272 is spherical. The track 261 extends substantially parallel to the extension direction of the main housing 111 and is disposed inside the housing 110. The connecting portion 271 can slide in the front-rear direction. The track 261 has a channel 262 that closes along its length direction. The channel 262 includes an opening 263 that opens forward. The inner surface of the channel 262 is curved, and the inner surface of the track 261 is cylindrical. The slider 272 is housed in the track 261, so that the light-emitting device 270 can be housed by sliding in the track 261. Any dimension of the cross-section of the slider 272 is larger than any dimension of the cross-section of the opening 263, so that the movement distance of the slider 272 is limited by the opening 263. In this embodiment, the diameter of the cross-section of the slider 272 is larger than the diameter of the cross-section of the opening 263. The slider 272 can move within the channel 262 but will not detach from the channel 262, making it convenient for the user to repeatedly move the connecting part 271 out of the receiving part 260 and put it back into the receiving part 260.
[0075] The light-emitting device 270 includes a light-emitting part 273, which can emit light. The light emitted by the light-emitting part 273 can be lamp light or light reflected through a special structure or coating. The light-emitting part 273 is connected to the connecting part 271. When the connecting part 271 moves relative to the receiving part 260, the light-emitting part 273 moves with the connecting part 271. The light-emitting device 270 is slidably received in the receiving part 260. In this embodiment, the light-emitting part 273 is rotatable relative to the connecting part 271. The connecting part 271 is slidable relative to the receiving part 260, and the light-emitting part 273 is rotatable relative to the connecting part 271. This allows the light-emitting part 273 to illuminate and indicate a larger range, providing more angles for the user to illuminate and indicate, and making it more convenient to use. It should be noted that rotation includes the rotation of the light-emitting part 273 around itself (rotation) and the rotation of the light-emitting part 273 relative to the connecting part 271 (revolution), and the manner of rotation is not limited here.
[0076] The light-emitting device 270 includes a flexible rod 274. The light-emitting part 273 is connected to the connecting part 271 via the flexible rod 274. The flexible rod 274 supports the light-emitting part 273. Thus, by operating the light-emitting part 273, the user applies force to the flexible rod 274, causing it to deform, thereby adjusting and fixing the position of the light-emitting part 273. The flexible rod 274 has a certain rigidity, and the diameter of its cross-section is smaller than the diameter of the opening 263. This allows the flexible rod 274 to pass through the opening 263 and be stored in the receiving part 260, resulting in a compact structure and convenient storage. The flexible rod 274 can both change the illumination range and angle through deformation and provide support for the light-emitting part 273, stabilizing the light source, and can also be stored in the receiving part 260, making it convenient to use.
[0077] At least a portion of the receiving part 260 is located above the trigger 1131, and the receiving part 260 is positioned above the fastener driver 100. The receiving part 260 can be designed to be relatively long in the front-to-back direction. The light-emitting device 270 is stored above the fastener driver 100, and the light-emitting device 270 can move a considerable distance back-to-back relative to the housing 110. The light-emitting device 270 has a large illumination and indication range, high space utilization, and an aesthetically pleasing appearance.
[0078] like Figures 27 to 29 As shown, in some embodiments, the receiving portion 260 is disposed substantially parallel to the extending direction of the transmission portion 112. The connecting portion 271 slides up and down in the receiving portion 260. The slider 272 is polygonal. The track 261 extends substantially parallel to the extending direction of the transmission portion 112 and is disposed outside the housing 110. The track 261 has a semi-open channel 262 along its length. The channel 262 includes an opening 263 that opens forward and upward. The opening 263 is C-shaped. The inner surface of the track 261 is movably engaged with the connecting portion 271 so that the connecting portion 271 can slide in the track 261 and can also stop at a certain position on the track 261. In some embodiments, the light-emitting portion 273 includes a pressing member 275, which allows the connecting portion 271 to slide relative to the receiving portion 260 when the user presses the pressing member 275, and fixes the connecting portion 271 relative to the receiving portion 260 when the user releases the pressing member 275.
[0079] The light-emitting part 273 includes a light-emitting diode 276 and a mounting housing 277. The light-emitting diode 276 is small in size, easy to store, and has low manufacturing cost. The mounting housing 277 secures the light-emitting diode 276 and prevents it from being damaged. The mounting housing 277 has ribs that hold the light-emitting diode 276 in place. When the user operates the light-emitting part 273, they can easily use it by pinching the mounting housing 277 with their fingers and dragging the light-emitting part 273.
[0080] like Figures 30 to 31 As shown, in some embodiments, there are multiple light-emitting devices 270, such as two or three. The light-emitting devices 270 are distributed around the ejection position of the fastener 10. The light-emitting devices 270 can be movable or fixed. Each light-emitting device 270 can be individually controlled to turn on and off, and its brightness can be individually controlled. In different usage environments, the user can select to turn on different light-emitting devices 270 to obtain suitable lighting brightness and angle. The user can also adjust the position of the shadow produced by the light illumination by individually adjusting the brightness of a light-emitting device 270. The user can clearly see the ejection position of the fastener 10, and the fastener driver 100 is easy to use.
[0081] like Figures 32 to 33As shown, in some embodiments, the transmission mechanism 140 includes a drive wheel 141 that drives the firing pin 131 to move. The transmission mechanism 140 also includes a first bevel gear 142 and a second bevel gear 143. A motor 160 drives the first bevel gear 142. The first bevel gear 142 and the second bevel gear 143 mesh, and the first bevel gear 142 drives the second bevel gear 143 to rotate. The second bevel gear 143 drives the drive wheel 141 to rotate via a shaft. The axes of rotation of the drive wheel 141 and the second bevel gear 143 are perpendicular to the axis of rotation of the first bevel gear 142. The drive wheel 141, the first bevel gear 142, and the second bevel gear 143 are substantially located below the firing pin 131. The distance between the first cylinder 151 and the motor 160 in the left-right direction is less than or equal to 15 mm. In some embodiments, the distance between the first cylinder 151 and the motor 160 in the left-right direction is less than or equal to 14 mm, 13 mm, 12 mm, 11 mm, or 10 mm.
[0082] This application also proposes another embodiment of a fastener driver 300, the structure of which is substantially the same as that of the fastener driver 300. The fastener driver 300 includes a magazine 340, a housing 310, and a guide assembly 380.
[0083] like Figures 34 to 37 As shown, the fastener driver 300 also includes a display device 330. The display device 330 displays visual information to the user by emitting light. The user observes the display device 330 with their eyes to obtain visual information. The display device 330 extends substantially along the extension direction a. The display device 330 includes a light-emitting portion 311, the length of which in the extension direction is greater than or equal to 30 mm. The length L4 of the light-emitting portion 311 in the extension direction a is greater than or equal to 50 mm. Because the length L4 of the light-emitting portion 311 in the extension direction a is long, the user can clearly observe the information displayed by the display device 330, and the display device 330 can display a wide variety of information types and a large amount of information. In some embodiments, the length L4 of the light-emitting portion 311 in the extension direction a is greater than or equal to 30 mm and less than or equal to 350 mm.

[0084] The display device 330 has a cross-sectional area in its vertical cross-section along the extending direction a. The cross-sectional area is greater than or equal to 0.2 cm². 2 and less than or equal to 30cm 2 In some embodiments, the cross-sectional area is greater than or equal to 0.5 cm². 2 And less than or equal to 25cm 2 In some embodiments, the cross-sectional area is greater than or equal to 1 cm². 2 And less than or equal to 20cm 2 In some embodiments, the cross-sectional area is approximately 2 cm². 2 3cm 2 4cm 2 5cm 2 6cm 2 7cm 2 8cm 2 9cm 2 10cm 2 or 15cm 2 .
[0085] The fastener driver 300 also includes a sensing device 320. The sensing device 320 senses the number of fasteners 10. The display device 330 displays visual information in response to the number of fasteners 10 sensed by the sensing device 320. The visual information displayed by the display device 330 includes illumination, off-center operation, flashing, color changing, and display of numbers, letters, or symbols. The user can obtain information such as the remaining number of fasteners through the visual information displayed by the display device 330. The sensing device 320 extends substantially along the extension direction a. The length L5 of the sensing device 320 in the extension direction a is greater than or equal to 50 mm. A longer length L5 in the extension direction a allows the sensing device 320 to sense a larger number of fasteners 10 and a wider sensing range. In some embodiments, the length L5 of the sensing device 320 in the extension direction a is greater than or equal to 30 mm and less than or equal to 350 mm. In some embodiments, the length L5 of the sensing device 320 in the extension direction a is greater than or equal to 40 mm and less than or equal to 300 mm.

[0086] The display device 330 has a first mode and a second mode. The display device 330 switches between the first mode and the second mode based on the number of fasteners 10 sensed by the sensing device 320. In the first mode, the light-emitting part 311 emits light. In the second mode, the light-emitting part 311 is off. The light-emitting part 311 includes a plurality of LED beads 312. The plurality of LED beads 312 are arranged along the extending direction a. The plurality of LED beads 312 are arranged along the extending direction of the magazine 340, resulting in a compact and aesthetically pleasing structure. In some embodiments, in the first mode, the light-emitting part 311 emits green light. In the second mode, the light-emitting part 311 emits red light. In some embodiments, in the first mode, the display device 330 displays a first digit. In the second mode, the display device 330 displays a second digit.
[0087] The fastener driver 300 includes a controller 221. The sensing device 320 includes a transmitter 321 and a receiver 322. The transmitter 321 is configured to transmit signals. The receiver 322 is configured to receive signals transmitted by the transmitter 321. When the receiver 322 receives a signal, the controller 221 controls the display device 330 to display corresponding visual information. A fastener 10 is disposed between the transmitter 321 and the receiver 322. The fastener 10 can block the transmission of signals between the transmitter 321 and the receiver 322. When the transmission of signals between the transmitter 321 and the receiver 322 is blocked by the fastener 10, the receiver 322 cannot receive the signals transmitted by the transmitter 321.
[0088] The display device 330 is disposed on the magazine 340. The sensing device 320 is disposed on the magazine 340. Both the display device 330 and the sensing device 320 are disposed on the magazine 340, resulting in a compact structure that facilitates sensing the number of fasteners 10 and displaying visual information. The display device 330 and at least some of the sensing devices 320 are located on both sides of the fastener 10. In this embodiment, the display device 330 and at least some of the sensing devices 320 are located on the left and right sides of the fastener 10, respectively. The display device 330 and the launching unit 321 are located on the left and right sides of the fastener 10, respectively. In some embodiments, the display device 330 and at least some of the sensing devices 320 may also be located on the top and bottom or front and rear sides of the fastener 10, respectively.
[0089] In this embodiment, the receiving unit 322 and the display device 330 are disposed on the same side of the magazine 340. A fastener 10 is disposed between the receiver 322 and the display device 330 and the transmitter 321. The fastener 10 is located on the transmission path of the signal emitted by the transmitter 321. The signal emitted by the transmitter 321 is a light signal, such as infrared light. In some embodiments, the signal emitted by the transmitter 321 may also be a magnetic signal or an electrical signal. When the magazine 340 is filled with fasteners 10, the fasteners 10 are located on the transmission path of the signal emitted by the transmitter 321, preventing all signal transmission from the transmitter 321 along the extension direction a. The display device 330 is in a first mode, and the light-emitting unit 311 emits light. All light-emitting units 311 along the extension direction a emit light, allowing the user to know that there are sufficient fasteners 10 and that replenishment is unnecessary. As the fasteners 10 in the magazine 340 are gradually consumed, the fasteners 10 move upwards. As the fastener 10 moves upward, the corresponding receiving position of the fastener 10 at the bottom of the magazine 340 becomes available. The signal transmission path, which was originally blocked by the fastener 10, becomes unobstructed, and the receiving part 322 at the bottom of the magazine 340 receives the signal emitted by the transmitting part 321. The controller 221 controls the LED 312 corresponding to the vacated position of the fastener 10 to turn off, and the display device 330 switches to the second mode. Along the extension direction a, as more and more LEDs 312 begin to turn off from the bottom of the magazine 340, the user can know that the number of fasteners 10 is gradually decreasing and can be replenished. The number of fasteners 10 is sensed by the sensing device 320 and displayed to the user by the display device 330. The user can easily know the number of fasteners 10 in various usage environments, making it convenient to use.
