Description

Technical Field

[0001] The present invention relates to the technical field of nail guns, in particular to a fastening tool. Background Art

[0002] A nail gun is a tool that uses spring force, pneumatic force, or gas as the driving force to drive nails. To drive nails, existing nail guns require the tool head to first contact the workpiece, causing the trigger lever to retract and close the safety switch, and then turning on the trigger switch to complete the nailing. Alternatively, while keeping the trigger switch closed, the tool head can be moved while contacting the workpiece, causing the trigger lever to retract and the safety switch to close to complete the nailing.

[0003] However, both of the above nailing methods require the trigger rod to be pressed against the workpiece, and then released and then pressed against the workpiece before the next nailing can be performed. However, due to the speed of raising the hand, the interval between the two nailing shots is relatively long, and the nailing efficiency is relatively low. Since a large force is applied when the trigger rod is pressed against the workpiece, when the workpiece is soft, such as when the trigger rod presses against cork, it is easy to cause damage to the workpiece. And because the trigger rod protrudes from the gun nozzle of the tool head, the protruding part of the trigger rod will cause interference when the tool head is pressed against the workpiece, making it impossible to nail when the tool head is tilted too much. At the same time, when using the nail gun for construction in a closed area, such as when working in a corner, nailing becomes difficult, that is, it cannot be used in multiple working conditions. Summary of the Invention

[0111] Figure 1 is a side view of the fastening tool of the present application. Figure 2 yes Figure 1 The cross-sectional structural diagram of the fastening tool shown in FIG. Figure 3 This is a schematic diagram of the partially disassembled structure of the fastening tool of this application. Figure 4 This is a side view of the fastening tool of the present application without the housing and the driving mechanism. Figure 5 yes Figure 4 The schematic diagram of the top view of the fastening tool shown in FIG. Figure 6 yes Figure 4 For the exploded schematic diagram of the fastening tool shown, please refer to Figures 1 to 6, the fastening tool is, for example, a nail gun; the fastening tool includes a housing 11, a power mechanism 12, a firing pin 13, a trigger switch 14, an operating portion 15a, a safety switch 16 and a trigger portion 17a, the power mechanism 12 being at least partially disposed in the housing 11; the firing pin 13 strikes the fastener along a striking direction driven by the power mechanism 12; the trigger switch 14 is operable to switch from an open state to a closed state; the operating portion 15a is used to respond to a user's triggering operation to drive the trigger portion 17a to move from an initial position to a working position, so that the safety switch 16 switches from an open state to a closed state; when the safety switch 16 and the trigger switch 14 are both in a closed state, the power mechanism 12 can drive the firing pin 13, and when the safety switch 16 and / or the trigger switch 14 are in an open state, the power mechanism 12 is prevented from driving the firing pin 13. In this embodiment, please refer to Figure 2 The power mechanism 12 includes a battery pack (not shown), a motor 122, a gearbox structure 123, a lifting structure 124, and an elastic assembly 125. The battery pack supplies power to the motor 122, causing the motor 122 to operate, thereby driving the gearbox structure 123, which in turn drives the lifting structure 124 to operate, causing the elastic assembly 125 to compress backward and accumulate energy to a predetermined position. The elastic assembly 125 then releases the energy, pushing the piston 126 forward, thereby driving the firing pin 13 fixed to the piston 126 forward to drive the fastener out of the gun nozzle 18. In other embodiments, the power mechanism 12 can also be a pneumatic mechanism or a gas mechanism, as long as it can drive the firing pin 13 to drive the nail, and is not limited to the above.

[0112] The operating portion 15a of the fastening tool of this embodiment responds to a user's triggering operation, driving the trigger portion 17a to move from an initial position to an operating position, thereby switching the safety switch 16 from an open state to a closed state. This eliminates the need to abut the working head against the workpiece during nailing, thereby achieving efficient nailing and preventing damage to the workpiece while also significantly reducing effort and providing enhanced operability. Furthermore, since there is no need to abut the working head against the workpiece to move the trigger lever, the trigger lever can be moved backward (from the initial position to the operating position) via the operating portion before the working head and workpiece are aligned, thus avoiding interference caused by the protruding trigger lever. This allows the fastening tool of this embodiment to be used for nailing at multiple angles and in multiple working conditions, such as cabinet door installation, baseboard installation, visual surface installation, door frame installation, and other work conditions requiring operation in confined spaces.

[0113] Alternatively, as Figure 4 、 Figure 5 and Figure 6As shown, the fastening tool further includes a linkage portion 22, which is linked to the operating portion 15a and the trigger portion 17a. The operating portion 15a is operable to move in response to a trigger operation, thereby driving the linkage portion 22 to move the trigger portion 17a. When the user triggers the operating portion 15a, the linkage portion 22 is driven, and the linkage portion 22 drives the trigger portion 17a from an initial position to an operating position. The linkage portion 22 is used to transmit the power of the operating portion 15a to move the trigger portion 17a.

[0114] Alternatively, as Figure 5 and Figure 6 As shown, the linkage portion 22 includes a first connection portion 221a and a second connection portion 223a. The operating portion 15a is operably connected to the first connection portion 221a. The first connection portion 221a can operably drive the second connection portion 223a to move, and the second connection portion 223a is connected to the trigger portion 17a. In this embodiment, the first connection portion 221a is a screw, and the second connection portion 223a is provided with a connection hole 103 corresponding to the first connection portion 221a. The first connection portion 221a passes through the connection hole 103 and connects to the operating portion 15a. For example, the first connection portion 221a and the second connection portion 223a are perpendicularly connected to each other. When the user triggers the operating portion 15a, the driving force is transmitted to the trigger portion 17a through the first connection portion 221a and the second connection portion 223a, driving the trigger portion 17a to move.

[0115] Optionally, the first connecting portion 221a is a screw that passes through the connecting hole 103 and is screwed to the operating portion 15a. The second connecting portion 223a is rod-shaped and extends along the striking direction. In this embodiment, since the first connecting portion 221a is screwed to the operating portion 15a, assembly is easy.

[0116] Optionally, the fastening tool further includes a locking portion that can be operated to lock the trigger portion 17a in the working position to keep the safety switch 16 in the closed state; and / or the locking portion can be operated to lock the trigger portion 17a in the initial position to keep the safety switch 16 in the open state. The locking portion of the present application can keep the trigger portion 17a in the locked state, eliminating the need to continuously trigger the operating portion 15a, which can cause hand fatigue.

[0117] Alternatively, as Figure 6As shown, the locking portion includes a positioning portion 231 and a first engaging portion 105 located between the trigger portion 17a and the operating portion 15a in the first direction of motion. The positioning portion 231 and the first engaging portion 105 are operably coupled to lock the trigger portion 17a in the operating position. This application locks the trigger portion 17a by combining the positioning portion 231 with the first engaging portion 105, resulting in a simple and easy-to-operate structure and preventing continuous triggering of the operating portion 15a. In this embodiment, the positioning portion 231 is connected to the second connecting portion 223a and is arranged to protrude toward the operating portion 15a.

[0118] Alternatively, as Figure 6 As shown, the locking portion also includes a second engaging portion 106 located between the trigger portion 17a and the operating portion 15a in the first movement direction, and the second engaging portion 106 and the first engaging portion 105 are arranged at intervals along the second movement direction; the positioning portion 231 and the second engaging portion 106 can be matched to lock the trigger portion 17a in the initial position.

[0119] The present application achieves locking of the trigger portion 17a by combining the positioning portion 231 with the second engaging portion 106. This provides a simple structure, ease of operation, and avoids continuous triggering of the operating portion 15a. Triggering the operating portion 15a along the first movement direction causes the positioning portion 231 to disengage from the first engaging portion 105 or the second engaging portion 106. After the positioning portion 231 disengages from the first engaging portion 105 or the second engaging portion 106, triggering the operating portion 15a along the second movement direction causes the positioning portion 231 to selectively engage with the first engaging portion 105 or the second engaging portion 106. In this embodiment, the first movement direction and the second movement direction are perpendicular to each other. For example, the first movement direction is parallel to the length of the first connecting portion 221a, and the second movement direction is parallel to the length of the second connecting portion 223a.

[0120] Optionally, the positioning portion 231 can be operated to move along the second movement direction to drive the positioning portion 231 to release the engagement with the first engaging portion 105; and / or to drive the positioning portion 231 to release the engagement with the second engaging portion 106. In this embodiment, operating the operating portion 15a along the second movement direction can drive the positioning portion 231 to move, so that the positioning portion 231 switches between the first engaging portion 105 and the second engaging portion 106.

[0121] Alternatively, as Figure 6As shown, the locking portion further includes a guide portion 232. The operating portion 15a is operable to respond to a triggering operation to drive the linkage portion 22 to slide relative to the guide portion 232 to drive the trigger portion 17a to move. In this embodiment, the guide portion 232 is fixed to the housing 11. The operating portion 15a can move relative to the guide portion 232 along a first movement direction to release the positioning portion 231 from the first engagement portion 105 or from the second engagement portion 106. When the positioning portion 231 is released from the first engagement portion 105, the operating portion 15a is triggered along a second movement direction, which can drive the linkage portion 22 to move synchronously, so that the positioning portion 231 is engaged with the second engagement portion 106. When the positioning portion 231 is released from the second engagement portion 106, the operating portion 15a is triggered along the second movement direction, which can drive the linkage portion 22 to move synchronously, so that the positioning portion 231 is engaged with the first engagement portion 105. The guide portion 232 of the present application can provide guidance for the operating portion 15a, ensuring that the operating portion 15a and the linkage portion 22 can move smoothly, and ensuring that the positioning portion 231 can be smoothly mated with the first engaging portion 105 and the second engaging portion 106. In this embodiment, the first engaging portion 105 and / or the second engaging portion 106 are, for example, sockets formed on the guide portion 232, and the positioning portion 231 can be inserted into the sockets to lock the trigger portion 17a in the operating position or the initial position.

[0122] Alternatively, as Figure 6 As shown, the guide portion 232 is provided with a slide groove 107 for the first connecting portion 221a to pass through. The first connecting portion 221a is connected to the operating portion 15a after passing through the slide groove 107. In this embodiment, the slide groove 107 extends along the second movement direction. When the operating portion 15a is moved along the second movement direction, the first connecting portion 221a can be driven to move within the slide groove 107.

[0123] Alternatively, as Figure 6 As shown, the fastening tool further includes a first support seat 24, which is supported between the linkage portion 22 and the guide portion 232. The first support seat 24 of the present application plays a supporting role during the process of the linkage portion 22 moving synchronously with the operating portion 15a, which can improve the stability of the linkage portion 22 and make it easier for the operating portion 15a to drive the linkage portion 22 to move synchronously. In this embodiment, the first support seat 24 is provided with a boss 241 on the side near the operating portion 15a. The boss 241 is at least partially disposed in the slide groove 107. The first support seat 24 is provided with a first through hole 109, and the first connecting portion 221a is disposed through the first through hole 109.

[0124] Alternatively, as Figure 5 and Figure 6As shown, a first accommodating groove 108 is provided on one side of the guide portion 232 close to the linkage portion 22, and the first accommodating groove 108 is extended along the second movement direction; the first support seat 24 is arranged in the first accommodating groove 108, and the opposite side walls of the first support seat 24 are in contact with or adjacent to the two groove walls of the first accommodating groove 108. The two groove walls of the first accommodating groove 108 serve as a guide for the first support seat 24, ensuring that the linkage portion 22 associated with the first support seat 24 can move stably.

[0125] Optionally, the fastening tool further includes a second support base 25, which is supported between the guide portion 232 and the operating portion 15a. The second support base 25 of the present application is used to support the operating portion 15a. The second support base 25 is slidably coupled to the guide portion 232. Triggering the operating portion 15a can drive the second support base 25 to move synchronously. The second support base 25 provides a movable bracket for the operating portion 15a, ensuring more stable movement of the operating portion 15a. In this embodiment, the operating portion 15a is connected to the second support base 25. The second support base 25 is provided with a second through hole 201. The first connecting portion 221a passes through the second through hole 201 and connects to the operating portion 15a.

[0126] Alternatively, as Figure 5 and Figure 6 As shown, a second accommodating groove 202 is provided on one side of the second support seat 25 close to the guide portion 232, and the second accommodating groove 202 is extended along the second movement direction; the guide portion 232 is at least partially arranged in the second accommodating groove 202, and the two outer walls of the guide portion 232 are in contact with or adjacent to the two groove walls of the second accommodating groove 202, and the two outer walls of the guide portion 232 serve as a guide for the second support seat 25, ensuring that the second support seat 25 and the operating portion 15a can move stably.

[0127] Alternatively, as Figure 5 As shown, the fastening tool further includes a first reset portion 26, which is configured to drive the trigger portion 17a to reset from the working position to the initial position. The first reset portion 26 of the present application can provide power to reset the trigger portion 17a. When the trigger operating portion 15a is triggered to move the trigger portion 17a from the initial position to the working position, the first reset portion 26 is driven by the operating portion 15a to store energy. When the trigger portion 17a needs to be reset, the operating portion 15a only needs to be released. At this time, the trigger portion 17a can be reset by relying on the first reset portion 26. In other words, the provision of the first reset portion 26 can simplify the structural design and make driving the trigger portion 17a to move more simply and conveniently. In this embodiment, the first reset portion 26 is, for example, a spring or a spring, but is not limited to this.

[0128] Alternatively, as Figure 4 、 Figure 5 and Figure 6As shown, the fastening tool also includes a depth adjustment assembly 27, which is operable to adjust the depth of the impact of the fastening portion. The depth adjustment assembly 27 is interlocked with the operating portion 15a. Triggering the operating portion 15a drives the depth adjustment assembly 27 to move synchronously. In this embodiment, the depth adjustment assembly 27 includes a depth adjustment member 271 and a rotating member 272. The rotating member 272 is mounted on the depth adjustment member 271. The depth adjustment member 271 has a threaded portion 2711. The trigger portion 17a has a threaded hole 101 that threadably engages with the threaded portion 2711. The second connecting portion 223a is connected to the depth adjustment member 271. By operating the rotating member 272 to drive the depth adjustment member 271 to rotate, the trigger portion 17a can move along the second motion direction to achieve position adjustment. In this embodiment, the first reset portion 26 is at least partially mounted on the depth adjusting member 271, the trigger portion 17a is connected to the depth adjusting assembly 27, and the linkage portion 22 is connected to the depth adjusting assembly 27; operating the trigger operating portion 15a can drive the linkage portion 22, the depth adjusting assembly 27 and the trigger portion 17a to move synchronously. At the same time, the first reset portion 26 realizes compression energy storage, and the first reset portion 26 relies on elastic force to drive the depth adjusting member 271 and the trigger portion 17a to move and reset.

[0129] Alternatively, as Figure 6 As shown, the depth adjusting member 271 is cylindrical and is arranged along the second movement direction. The rotating member 272 is circular and has side teeth on its edge to facilitate the rotation of the rotating member 272.

[0130] Alternatively, as Figure 5 and Figure 6 As shown, the fastening tool further includes a connecting rod 174a. The trigger portion 17a and the connecting rod 174a are connected at both ends of the depth adjustment assembly 27, respectively. The connecting rod 174a is configured to trigger the safety switch 16, closing the safety switch 16, when the operating portion 15a responds to a user operation. In this embodiment, the trigger portion 17a and the connecting rod 174a are both connected to the depth adjustment member 271. Triggering the operating portion 15a can drive the trigger portion 17a, the depth adjustment member 271, and the connecting rod 174a to move synchronously.

[0131] The depth adjustment component 27 of the present application is used to adjust the position of the trigger part 17a. The depth adjustment component 27 is linked to the operating part 15a. When the operating part 15a is triggered, the depth adjustment component 27 is driven to move synchronously.

[0132] Alternatively, as Figure 5 and Figure 6As shown, the fastening tool also includes a second reset portion 28, which is configured to reset the operating portion 15a. In this embodiment, one end of the second reset portion 28 abuts against the boss 241, and the other end of the second reset portion 28 abuts against the operating portion 15a. The second reset portion 28 of the present application can provide power to reset the operating portion 15a. When the operating portion 15a is triggered to move the trigger portion 17a from the initial position to the working position, the second reset portion 28 is driven by the operating portion 15a to store energy. When the operating portion 15a needs to be reset, the operating portion 15a only needs to be released. At this time, the second reset portion 28 can be used to reset the operating portion 15a and the trigger portion 17a. In other words, the provision of the second reset portion 28 can simplify the structural design and make it easier and more convenient to drive the operating portion 15a to move. In this embodiment, the second reset portion 28 is, for example, a spring or a spring, but is not limited to this.

[0133] Alternatively, as Figure 1 As shown, the trigger switch 14 includes a trigger 141. The trigger 141 and the operating portion 15a are both provided on the housing 11 and are located within an area that can be operated simultaneously by one hand of the user. In this way, the operator can complete the operation with one hand, which is convenient to operate.

[0134] Figure 7 This is a structural diagram of a fastening tool according to an embodiment of the present application without the housing and the driving mechanism. Figure 8 yes Figure 7 The exploded structural diagram of the fastening tool shown is Figure 9 This is a schematic diagram of the structure of the operation part and the linkage part of this embodiment. Figure 7 、 Figure 8 and Figure 9 As shown, the end of the operating portion 15b of this embodiment is provided with a first inclined surface 151, and the end of the linkage portion 22 facing the operating portion 15b is provided with a second inclined surface 224. The operating portion 15b responds to the trigger operation so that the first inclined surface 151 can push the second inclined surface 224 to drive the linkage portion 22 to drive the trigger portion 17b to move. When the operating portion 15b is pressed along the first movement direction, the operating portion 15b pushes the second inclined surface 224 through the first inclined surface 151, causing the linkage portion 22 to move as a whole along the second movement direction, and ultimately driving the trigger portion 17b to move. The present application can drive the trigger portion 17b to move by cooperating with the first inclined surface 151 of the operating portion 15b and the second inclined surface 224 of the linkage portion 22, without the need for a complex structure, which not only simplifies the structural design but also reduces production costs.

[0135] like Figure 7 and Figure 8 As shown, the first connecting portion 221b of this embodiment is Figure 5 and Figure 6The structure of the first connecting portion 221a shown is different; in this embodiment, the second inclined surface 224 is arranged on the first connecting portion 221b; the first connecting portion 221b and the second connecting portion 223b can be fixedly connected, or they can be detachably connected through the cooperation of a card slot and a card block. For example, the first connecting portion 221b is provided with a first card slot and a first card block, and the second connecting portion 223b is provided with a second card slot and a second card block. The first card block is arranged in the second card slot, and the second card block is arranged in the first card slot.

[0136] like Figure 9 As shown, one end of the second reset portion 28 of this embodiment is sleeved on the end of the operating portion 15 b , and the other end of the second reset portion 28 abuts against the housing 11 . The second reset portion 28 is used to drive the operating portion 15 b to reset.

[0137] Alternatively, as Figure 7 and Figure 8 As shown, the fastening tool further includes a connecting rod 174b. The two ends of the depth adjustment assembly 27 are connected to the trigger portion 17b and the connecting rod 174b, respectively. The connecting rod 174b is configured to trigger the safety switch 16 when the operating portion 15b responds to a user operation. In this embodiment, one end of the connecting rod 174b is connected to the second connecting portion 223b, and the other end of the connecting rod 174b is connected to the depth adjustment member 271 of the depth adjustment assembly 27. When the operating portion 15b is pressed in the first movement direction, the operating portion 15b pushes the second inclined surface 224 via the first inclined surface 151, causing the entire linkage portion 22 to move in the second movement direction. At this time, the connecting rod 174b triggers the safety switch 16, closing it and driving the depth adjustment member 271 and the trigger portion 17b to move synchronously. The structural composition of the depth adjustment assembly 27 is described above. The interference member 273 of the above embodiment and the connecting rod 174b of this embodiment may be detachably connected or integrally formed.

[0138] Alternatively, as Figure 7 As shown, the second connecting portion 223b is provided with a plug hole 104 at one end away from the operating portion 15b, and the end of the connecting rod 174b is inserted into the plug hole 104; this design makes it easy to separate the second connecting portion 223b and the connecting rod 174b, convenient for disassembly and maintenance.

[0139] Alternatively, as Figure 7 As shown, the trigger portion 17b includes a first section 1721 and a second section 1722 connected to each other. The first section 1721 is at least partially disposed in the channel formed by the muzzle cover 181 and the trigger portion cover 182. The second section 1722 is away from the first section.

[0140] One end of 1721 is connected to the depth adjustment member 271. For example, the second section 1722 is provided with a threaded hole 101 for mounting the depth adjustment member 271. The depth adjustment member 271 is connected to the threaded hole 101 via a threaded portion 2711. In this embodiment, the first section 1721 and the second section 1722 can be detachably connected via a fixing slot and a fixing block, or the first section 1721 and the second section 1722 can be integrally formed. The design can be freely adjusted according to actual needs.

[0141] In another preferred embodiment, Figure 10 : is a structural diagram of the connection between the second connecting portion and the second triggering portion of another embodiment of the present application, such as Figure 10 As shown, in this embodiment, a connecting hook 2231 is provided at one end of the second connecting portion 223b away from the operating portion 15b, and a hooking groove 102 that cooperates with the connecting hook 2231 is provided on the connecting rod 174b.

[0142] Figure 11 is a schematic diagram of the three-dimensional structure of a fastening tool according to another embodiment of the present application. Figure 12 yes Figure 11 The partially enlarged structural diagram of the fastening tool shown is as follows, Figure 13 This is a schematic diagram of the structure of the fastening tool of the present application after the operating part is locked. Figure 14 This is a schematic structural diagram of another embodiment of the fastening tool of the present application after removing half of the housing and the driving mechanism. Figure 15 yes Figure 14 Please refer to the schematic diagram of the structure of the fastening tool after removing the shell. Figures 11 to 15 In this embodiment, the operating portion 15c pivots the linkage portion 22 in response to a trigger operation, thereby driving the trigger portion 17b to move. The operating portion 15c of this embodiment transmits power through the pivot mechanism of the linkage portion 22, utilizing the principle of leverage to reduce the effort required to press the operating portion 15c. This not only simplifies operation but also reduces production costs.

[0143] like Figure 15 As shown, the first connecting portion 221c of this embodiment is a pivot rod, and the first connecting portion 221c is rotatably connected to the shell 11 through a rotating shaft; when the operating portion 15c is pressed along the first movement direction, the operating portion 15c pushes the first connecting portion 221c to rotate around the rotating shaft, so that the first connecting portion 221c drives the second connecting portion 223c, the depth adjustment assembly 27 and the trigger portion 17b to move synchronously. During this process, the second connecting portion 223c pulls the connecting rod 174b, so that the connecting rod 174b triggers the safety switch 16.

[0144] The connection method between the second connecting portion 223c and the connecting rod 174b of this embodiment can be referred to above. Figure 7 、 Figure 10 As shown in the above content, I will not repeat it here.

[0145] Alternatively, as Figure 11 and Figure 13 and Figure 14 As shown, in this embodiment, the locking portion includes a locking member 233 operably connected to the housing 11. The locking member 233 abuts the operating portion 15c to lock the operating portion 15c. In this embodiment, the locking member 233 is, for example, a screw. One end of the locking member 233 passes through the housing 11 and abuts the operating portion 15c, thereby locking the operating portion 15c and eliminating the need to continuously press the operating portion 15c, which may cause hand fatigue.

[0146] Specifically, such as Figure 11 and Figure 13 As shown, the locking portion further includes a blocking member 234 that cooperates with the locking member 233. The blocking member 234 is provided with a through hole for the locking member 233 to pass through. The housing 11 is provided with a locking hole 203 that connects to the locking member 233. The blocking member 234 covers the operating portion 15c and allows the locking member 233 to pass through the through hole and engage with the locking hole 203, thereby locking the operating portion 15c. To unlock the operating portion 15c, the locking member 233 and blocking member 234 are removed, and the operating portion 15c is reset by the elastic force of the second reset portion 28. In this embodiment, when the operating portion 15c is not pressed, the end of the operating portion 15c protrudes from the housing 11. When the operating portion 15c is pressed, the operating portion 15c at least partially retracts into the housing 11. In other embodiments, the locking member 233 and the blocking member 234 can be integrally formed, that is, the blocking member 234 is equivalent to the head of the locking member 233, which is used to lean against the shell 11 to limit the operating part 15c, and the rod of the locking member 233 cooperates with the locking hole 203 of the shell 11 to achieve a fastened connection.

[0147] Furthermore, to address issues such as low nailing efficiency and workpiece damage, prior art techniques involve moving the trigger units 17a, 17b from their initial positions to their working positions. A trigger unit cover, in conjunction with a screw, locks the trigger unit 17a in a position that keeps the safety switch 16 closed. Nailing can now be achieved simply by operating the trigger switch 14. While this improves nailing efficiency, it requires removing the trigger unit cover from the gun nozzle cover, moving the trigger units 17a, 17b, and then re-engaging the trigger unit cover with screws to lock the trigger units 17a, 17b in the locked position. This method is cumbersome and, due to the frequent removal of the trigger unit cover, can easily damage the gun nozzle.

[0148] To this end, this embodiment discloses a tightening tool that is easier to operate and more efficient. The following will explain the differences between this embodiment and the above embodiment. The same reference numerals have been assigned to the same parts as the tightening tools of the above embodiment, and the same structures will not be repeated here. Specifically, Figure 16 and Figure 17 As shown, the trigger portion 17c of the fastening tool is operably moved relative to the housing 11 from an initial position along a moving path to a working position, so that the safety switch 16 is switched from an open state to a closed state. When the safety switch 16 and the trigger switch 14 are both in a closed state, the power mechanism 12 is allowed to drive the striker 13. When the safety switch 16 and / or the trigger switch 14 are in an open state, the power mechanism 12 is prevented from driving the striker 13. The fastening tool also includes a limiting portion 180, which is configured to limit the trigger portion 17c from deviating from the moving path. The fastening tool is operably switched between a first state and a second state. During the switching process, the limiting portion 180 always maintains no relative movement with the housing 11. When the fastening tool is in the first state, the trigger portion 17c is operably moved between the initial position and the working position. When the fastening tool is in the second state, the trigger portion 17c is in the working position and locked in the working position, so that the safety switch 16 remains in a closed state.

[0149] The fastening tool of this embodiment has a first state and a second state. When switched to the first state, it can meet the needs of conventional nailing. When switched to the second state, it can meet the needs of multi-angle nailing and efficient nailing. In the process of switching between the first state and the second state, the limiting part always maintains no relative movement with the shell, that is, the limiting part never needs to be disassembled and remains in a fixed position. For the user, the number of parts to be disassembled and assembled is reduced, which avoids tedious disassembly and assembly operations and the loss of parts. The disassembly and assembly of the trigger part is simpler and more efficient.

[0150] In some embodiments, as Figure 1 , Figure 16 and Figure 17 As shown, the fastening tool also includes a muzzle 18. When the power mechanism 12 drives the striker 13 in the striking direction to strike the fastening portion, the fastening portion is ejected from the muzzle 18. The muzzle 18 includes a muzzle cover plate 181 and a trigger cover plate 182 that are connected to each other. The limiting portion 180 is at least partially formed by the trigger cover plate 182 and the muzzle cover plate 181. The muzzle cover plate 181 and the trigger cover plate 182 together form a movement path. This arrangement, using the connected trigger cover plate and the muzzle cover plate to form the movement path of the trigger portion, is simple and convenient.

[0151] In some embodiments, as Figure 17 and Figure 18 As shown, the locking portion includes a first locking portion 20A and a second locking portion 20B. The first locking portion 20A is connected to the housing 11 without relative movement, while the second locking portion 20B is disposed on the trigger portion 17c and operably engages with the first locking portion 20A to lock the trigger portion 17c in the working position. This arrangement makes locking the trigger portion simple and clear, making it easy and efficient for the user to switch the fastening tool state.

[0152] Optionally, the second locking portion 20B includes a snap-fit ​​member disposed on the trigger portion 17c, and the first locking portion 20A is configured as a buckle disposed on the housing 11 or the muzzle cover 181. By moving the trigger portion 17c, the snap-fit ​​member engages with the buckle, thereby locking the trigger portion to the housing or muzzle cover. Alternatively, the buckle may be disposed on the second locking portion 20B, and the snap-fit ​​member may be disposed on the housing or muzzle cover. It is sufficient that the trigger portion is locked by a snap-fit ​​method, and this is not particularly limited herein.

[0153] Alternatively, as Figure 17 and Figure 18 As shown, the second locking portion 20B includes a fitting, which is provided on the trigger portion 17c; the locking portion further includes a fixing member 173, which is operably connected to the first locking portion 20A and the fitting to lock the trigger portion 17c in the working position.

[0154] Specifically, if Figure 17 and Figure 18 As shown, the first locking portion 20A is configured as a locking hole 1810, and the matching piece is configured as a matching hole 1721c. When the trigger portion 17c moves to the working position, the locking hole 1810 is opposite to the matching hole 1721c, and the fixing piece 173 passes through and connects the locking hole 1810 and the matching hole 1721c to lock the trigger portion 17c relative to the shell 11.

[0155] More specifically, Figure 17 and Figure 18 As shown, a locking hole 1810 is provided on the muzzle cover 181, and a matching hole 1721c is provided on the trigger portion 17c, specifically on the end of the trigger portion 17c facing away from the striking direction. When the trigger portion 17c is moved to the operating position, the locking hole 1810 and the matching hole 1721c are aligned, and the fixing member 173 passes through and connects the locking hole 1810 and the matching hole 1721c, thereby locking the trigger portion 17c to the muzzle cover 181. The fixing member 173 can optionally be a screw or a fixing pin, without particular limitation. This arrangement allows the user to lock the trigger portion in the operating position by simply moving the trigger portion, aligning the locking hole with the matching hole, and then locking the trigger portion in the operating position with the screw or fixing pin. This reduces the number of locking components and simplifies the operation, thus improving operational efficiency.

[0156] In some embodiments, as Figure 18 As shown, the fastening tool also includes a depth adjustment component 27, which is operable to adjust the depth of the fastening part being struck; the depth adjustment component 27 is linked to the trigger part 17c, and when the trigger part 17c switches between the initial position and the working position, the depth adjustment component 27 moves synchronously.

[0157] In some embodiments, as Figure 18 As shown, the fastening tool also includes a connecting rod 174c, and the two ends of the depth adjustment assembly 27 are respectively connected to the trigger part 17c and the connecting rod 174c. When the fastening tool is in the second state, the trigger part 17c drives the depth adjustment assembly 27 and the connecting rod 174c to move synchronously, and the end of the connecting rod 174c triggers the safety switch 16.

[0158] Specifically, if Figure 18 As shown, the depth adjustment assembly 27 includes a depth adjustment member 271 and a rotating member 272. The rotating member 272 is sleeved on the depth adjustment member 271. The depth adjustment member 271 is provided with a threaded portion 2711. The triggering portion 17c is provided with a threaded hole 101, which threadedly engages with the threaded portion 2711. The connecting rod 174c has a resistance member 273 at one end near the rotating member 272. The resistance member also has a corresponding threaded hole (not shown) that engages with the threaded portion (not shown) on the depth adjustment member 271. In this embodiment, the first return member 26 is at least partially sleeved on the depth adjustment member 271, with one end of the first return member 26 abutting against the resistance member 273 and the other end abutting against the housing. The two ends of the depth adjustment rod 271 are respectively connected to the trigger part 17c and the connecting rod 174c. When the trigger part 17c is moved, the trigger part 17c, the depth adjustment assembly 27 and the connecting rod 174c can be driven to move synchronously. The end of the connecting rod 174c triggers the safety switch 16. At the same time, the first reset part 26 realizes compression energy storage. The first reset part 26 relies on elastic force to drive the connecting rod 174c, the depth adjustment part 271 and the trigger part 17c to move and reset.

[0159] In some embodiments, the fastening tool is further provided with operating parts 15a, 15b, 15c and a locking part. The operating parts 15a, 15b, 15c are used to respond to the user's trigger operation to drive the trigger parts 17a, 17b to move from the initial position to the working position, so that the safety switch 16 is switched from the open state to the closed state; the locking part is used to keep the trigger parts 17a, 17b in the working position. The specific structure of the fastening tool including the operating parts 15a, 15b, 15c and the locking part can be referred to above. Figures 1 to 15 As shown in the above content, no specific limitation is made here.

[0160] The present application also discloses an operating method for a fastening tool that is easier to operate and more efficient. The fastening tool of this embodiment can be referred to Figure 16 、 Figure 17 As shown in the above content, no further details will be given here. Figure 16 and Figure 17As shown, the fastening tool includes a limiting portion 180 configured to limit the trigger portion 17c from deviating from the moving path; and further includes a locking portion operable to lock the trigger portion 17c in the working position so that the safety switch 16 remains in the closed state; the operating method is configured to switch the fastening tool between the first state and the second state, and during the execution of the operating method, the limiting portion 180 always maintains no relative movement with the housing 11; as shown Figure 16 As shown, when the fastening tool is in the first state, the trigger portion 17c is operable to move between the initial position and the working position, as shown in FIG. Figure 17 As shown, when the fastening tool is in the second state, the trigger portion 17c is in the working position and locked in the working position, so that the safety switch 16 remains in the closed state; when the fastening tool is switched from the first state to the second state, the operating method includes performing the following steps:

[0161] Step 1: Move the trigger portion 17c from the initial position along the moving path to the working position;

[0162] Step 2: Lock the trigger portion 17c at the working position via the locking portion.

[0163] In this way, locking the trigger part keeps the safety switch in a closed state. The user only needs to move the trigger part and lock it in two steps. During this process, the limiting part always maintains no relative movement with the shell, that is, there is no need to disassemble or move the limiting part when locking the trigger part. The locking steps are simple, fewer parts need to be moved or disassembled for locking, and the user operation efficiency is high.

[0164] In some embodiments, as Figure 18 As shown, the locking portion includes a first locking portion 20A, which is connected to the housing 11 without relative movement. The locking portion also includes a second locking portion 20B, which is provided on the trigger portion 17c. The second locking portion 20B is operably matched with the first locking portion 20A to lock the trigger portion 17c in the working position.

[0165] In some embodiments, as Figure 18 As shown, the second locking portion 20B includes a matching piece, which is arranged on the trigger portion 17c. The locking portion also includes a fixing piece 173. Step 2 includes: fixing the first locking portion 20A and the matching piece together through the fixing piece 173 to lock the trigger portion 17c in the working position.

[0166] Specifically, if Figure 16As shown, the trigger portion 17c has not been locked in the working position and can move between the initial position and the working position. At this time, the fastening tool can meet the needs of conventional nailing. The user holds the fastening tool and presses the trigger portion 17c against the workpiece to overcome the elastic force of the first reset portion 26. At this time, the trigger portion 17c moves backward due to being pressed against the workpiece, driving the depth adjustment component 27 and the connecting rod 174c to move backward synchronously. Therefore, the end of the connecting rod 174c triggers the safety switch 16 to close the safety switch 16. The conventional nailing needs can be met according to the nailing mode specifically selected by the user. Figure 16 As shown, the trigger portion 17c is provided with a matching hole 1721c, specifically provided at the end of the trigger portion 17c away from the striking direction, and the matching lock hole 1810 is provided on the muzzle cover 181, and the lock hole 1810 is provided at the substantially rear end of the muzzle cover 181 away from the striking direction. Figure 17 As shown, in order to meet the needs of efficient nailing, the user can move the trigger part 17c backward to overcome the elastic force of the first reset part 26, so that the locking hole 1810 and the matching hole 1721c are aligned in the up and down directions, and connect the locking hole 1810 and the matching hole 1721c through the fixing part 173, thereby locking the trigger part 17c in the working position.

[0167] In some embodiments, step 2 is performed directly after step 1. This arrangement simplifies the steps of locking the trigger portion, and the user's locking operation is simple and efficient.

[0168] In some embodiments, when the fastening tool is switched from the second state to the first state, the operating method includes performing the following steps: unlocking the locking portion to allow the trigger portion 17c to be operably moved between the initial position and the working position.

[0169] Specifically, if Figure 17 As shown, the trigger portion 17c is now locked in the working position. When the user wishes to unlock it, they only need to remove the fixing member 173 to disengage the lock hole 1810 from the mating hole 1721c. The trigger rod 17c then automatically returns to its initial position under the action of the first reset portion 26. This arrangement allows unlocking the trigger portion in a single step, which is simple and straightforward, without the need for complicated steps or excessive parts handling, thus preventing the loss of parts during the unlocking process.

[0170] In addition, in some embodiments, the fastening tool also includes a continuous nailing mode and a single nailing mode, wherein the single nailing mode is to first abut the tool head against the workpiece, so that the trigger rod retracts and the safety switch is closed, and then the trigger switch is turned on to complete a nailing; the continuous nailing mode is: while keeping the trigger switch closed, the tool is moved while the tool head is abutted against the workpiece, so that the trigger rod retracts and the safety switch is closed, and then nailing is performed.

[0171] Ginseng Figure 12 As shown, the fastening tool of this embodiment also includes a control unit (not shown) and a mode switching button 19. The trigger switch 14 can be in a closed state and send a first closed signal in response to the user's first trigger operation; the safety switch 16 has a closed state and an open state. When the safety switch 16 is in the closed state, it can send a second closed signal; the trigger part 17a, 17b can move from the initial position to the working position to trigger the safety switch 16 to put the safety switch 16 in a closed state; the control unit is electrically connected to the safety switch 16 and the trigger switch 14, and is used to control the power mechanism 12 to drive the firing pin 13; the mode switching button 19 can switch the fastening tool between continuous shooting mode and single shooting mode in response to user operation.

[0172] When the fastening tool is switched to the continuous striking mode, the control unit controls the power mechanism 12 to drive the striker 13 only when it first receives the first closing signal from the trigger switch 14 and then receives the second closing signal from the safety switch 16 .

[0173] When the fastening tool is switched to single-shot mode, the control unit controls the power mechanism 12 to drive the striker 13 only when it first receives the second closing signal from the safety switch 16 and then receives the first closing signal from the trigger switch 14.

[0174] The single-hitting mode includes a special single-hitting mode. When the fastening tool is switched to the special single-hitting mode, the safety switch 16 always sends a second closing signal.

[0175] In this embodiment, the safety switch and trigger switch are closed in a pre-set sequence in both single-shot and continuous-shot modes, with the control unit controlling the power mechanism 12 to drive the striker 13. This prevents the problem of accidental nailing caused by an unpredictable closing sequence of the safety switch 16 and trigger switch 14, thereby enhancing nailing safety. Furthermore, since a special single-shot mode with a normally closed safety switch is set within the single-shot mode, nailing efficiency is increased when the user switches to this special single-shot mode.

[0176] In addition, in this embodiment, the fastening tool is further provided with operating parts 15a, 15b, 15c, which are used to respond to the user's triggering operation to drive the trigger parts 17a, 17b to move from the initial position to the working position, so as to switch the safety switch 16 from the open state to the closed state. The specific structure of the fastening tool including the operating parts 15a, 15b, 15c is described above. Figures 1 to 15 As shown in the above content, no specific limitation is made here.

[0177] Optionally, when the fastening tool is in the continuous-tightening mode, the control unit is configured to output an abnormality signal based on the continuous receipt of the first closing signal and the absence of the second closing signal within a preset time, thereby improving safety.

[0178] Optionally, when the fastening tool is in the single-shot mode, the control unit continuously receives the second closing signal from the safety switch 16 within a preset time, and the fastening tool switches to the special single-shot mode.

[0179] Alternatively, as Figure 11 and Figure 12 As shown, the fastening tool also includes an operation panel 21, which is arranged above the battery pack mounting base 112 and below the handle 113. A mode switching button 19 and an indicator light are provided on the operation panel 21. The mode switching button 19 is operated to switch the mode, and the indicator light corresponding to the mode is lit to indicate that the mode is selected. There can be one mode switching button and two indicator lights, such as a single indicator light 211 indicating a single mode and a continuous indicator light 212 indicating a continuous mode. For example, if the mode switching button 19 is short pressed (the pressing time is, for example, less than 1s), the single indicator light 211 will light up, indicating that the fastening tool has entered the single mode; if the mode switching button 19 is short pressed again, the single indicator light 211 will go out, and the continuous indicator light 212 will light up, indicating that the fastening tool has switched from the single mode to the continuous mode. When the mode switching button 19 is pressed for a long time (for example, the pressing time is greater than 1s), the single-shot indicator light 211 and the continuous-shot indicator light 212 are both lit, and the fastening tool enters the special single-shot mode. After entering the special single-shot mode, the operating parts 15a, 15b, and 15c are operated to drive the trigger parts 17a and 17b to move from the initial position to the working position and lock them.

[0180] In addition, in an optional embodiment, after entering the single-shot mode, the operating parts 15a, 15b, 15c can be directly operated to drive the trigger parts 17a, 17b to move from the initial position to the working position and lock it, so that the safety switch 16 always sends a second closing signal to enter the special single-shot mode.

[0181] In another preferred embodiment, there can be three indicator lights, for example, a single indicator light 211 indicating a single mode, a continuous indicator light 212 indicating a continuous mode, and a special single indicator light indicating a special single mode; by short pressing the mode switching button 19 to switch in sequence, the lights light up in sequence to indicate that the corresponding mode is selected.

[0182] In addition, in this embodiment, the operation panel is provided with a power button 214. After the battery pack is installed in the battery pack mounting base 112, the power button 214 is pressed to power on the tool. At this time, all indicator lights flash to indicate power on, or a single power indicator light 213 is provided to indicate power on. Alternatively, power on can be performed by pulling the trigger 141.
