As examples, second alignment structure 418 may comprise one or more of a pin shaft, pin, pin body and pin cap, stop-block, groove, clamping pin, etc. Locking piece 424 may comprise one or more of a locking hook (e.g., moveably arranged), a knob (e.g., rotatably arranged), an eccentric piece (e.g., rotatably arranged), a sliding block, etc. In some examples an actuator (e.g., button, knob, etc.), not shown at FIG. 49, may be included to enable the locking piece 424 and second alignment structure 418 to engage and disengage. It may be understood that in some examples, second alignment structure 418 may be included as part of fastener cartridge 455 while locking piece 424 may be included as part of gun body 450, without departing from the scope of this disclosure. There may be one second alignment structure 418 and one locking piece 424 in some examples, although in other examples there may be a plurality of second alignment structures 418 and/or a plurality of locking pieces 424.
Fastener gun 400 may further comprise one or more guide structures and one or more fitting structures. As an example, FIG. 49 depicts guide structure 416 associated with gun body 450, and fitting structure 422 associated with fastener cartridge 455. It may be understood that guide structure 416 and fitting structure 422 may be physically coupled and decoupled in order to attach and detach, respectively, fastener cartridge 455 and gun body 450. While guide structure 416 is depicted as being arranged on gun body 450 and fitting structure 422 is depicted as being arranged on fastener body 455, in other examples guide structure 416 may be arranged on fastener body 455 and fitting structure 422 may be arranged on gun body 450, without departing from the scope of this disclosure. The guide structure may comprise a female-type connector or connectors while the fitting structure may comprise a male-type connector or connectors, in some examples. In alternative examples, the fitting structure may comprise a female connector or connectors while the guide structure may comprise a male connector or connectors. As one example, the guide structure may be one of a dovetail and a dovetail groove, and the fitting structure may be the other of the dovetail and the dovetail groove. As another example, the guide structure may be one of a tenon and a mortise, and the fitting structure may be the other of the tenon and the mortise. As another example, the guide structure may be one of a convex block or blocks and a groove or grooves, and the fitting structure may be the other of the convex block or blocks and the groove or grooves.
Thus, it may be understood that nail gun 400 enables fastener cartridges to be readily changed by detaching a particular fastener cartridge 455 from gun body 450 and then attaching another particular fastener cartridge 455 to gun body 450. It may be understood that particular fastener cartridges 455 may include in some examples different fasteners (e.g., one nail-type fastener and one staple-type fastener), that can still each be used with a same gun body 450. In other words, gun body 450 may accept a variety of fastener cartridges 455 storing different fastener types. In this way, the same gun body 450 can be used, for example, to drive nails into a medium in one example and staples into a medium in another example, without compromising operational effectiveness and by simply swapping out fastener cartridges.
FIG. 49 is presented as a representative example to illustrate particular relevant aspects of a modular fastener gun of the present disclosure that enables a single gun body 450 to accept and work functionally with any number of different fastener cartridges 455. However, not all aspects of FIG. 49 are present in each and every embodiment discussed herein, and the structural makeup of each different embodiment is elaborated infra.

A torque direction of the first torsion spring 108 is opposite the direction in which the hanging hook 1071 rotates when being pushed by the handgrip 1072. As shown in FIG. 5, the first locking hook 107 hooks a pin shaft 213 such that the fastener box component 2 is connected to the connecting portion 101. If the fastener box component 2 needs to be disassembled, it is only necessary to hold the handgrip 1072 with a hand to drive the hanging hook 1071 to rotate clockwise. The handgrip 1072 needs to overcome the torque of the first torsion spring 108 to push the hanging hook 1071 to rotate clockwise. In this case, the first torsion spring 108 deforms to generate torque. The torque of the first torsion spring 108 may enable the hanging hook 1071 to reset and help keep the hanging hook 1071 at a desired position. In the state shown in FIG. 5, the handgrip 1072 is rotatable relative to the hanging hook 1071. Therefore, when the hanging hook 1071 hooks the pin shaft 213, the handgrip 1072 may rotate counterclockwise to be lapped over the crossbeam 109. In this way, a worker may hold the grasping portion 102 with a hand to prevent the handgrip 1072 from hindering the hand.
As shown in FIGS. 12 and 13, the power member 13 fits with the stroke cavity 1031 in structure and shape, and is suitable for being driven by power air to move in the stroke cavity 1031.

Embodiment 7
As shown in FIG. 36 to FIG. 43, the lower end of the connecting portion 101 is provided with a first dovetail groove 701 and a counterbore 702. A step 709 is provided in the counterbore 702. The counterbore 702 is provided with a fourth groove 703 and a stop wall 704. The fourth groove 703 and the stop wall 704 respectively extend in opposite directions from the step 709. An extension direction of the first dovetail groove 701 is perpendicular to an axial direction of the counterbore 702.
The connecting portion 101 is provided with an eccentric piece 705. The eccentric piece 705 is rotatably arranged. The eccentric piece 705 may be an eccentric shaft or a shaft with a semicircular sectional surface or an arc-shaped sectional surface. The eccentric piece 705 is rotatably plugged in the counterbore 702. One end of the eccentric piece 705 is provided with a handle 706, and the other end is provided with a clamping pin 707. The clamping pin 707 penetrates the eccentric piece 705 and protrudes from the eccentric piece 705 from two sides. The clamping pin 707 is located in the counterbore 702 and is rotatable along with the eccentric piece 705. The stop wall 704 is located in a rotational direction of the eccentric piece 705 and is used to restrict a rotation angle of the eccentric piece 705. The clamping pin 707 rotates along the step 709 and may enter the fourth groove 703 during rotation. The eccentric piece 705 is sleeved with a compression spring 708, also referred to herein as a fifth elastic reset device. One end of the compression spring 708 abuts against the connecting portion 101, and the other end abuts against the handle 706. The compression spring 708 has an elastic force when being compressed. The elastic force abuts against the handle 706 to enable the clamping pin 707 to abut against the connecting portion 101. For example, the clamping pin 707 needs to move out of the fourth groove 703 to abut against the step 709. The compression spring 708 needs to be pressed to enable the elastic force of the compression spring 708 to further increase. In this case, the clamping pin 707 abuts against the connecting portion 101 with a greater force. That is, when the clamping pin 707 abuts against the step 709, the clamping pin is more difficult to rotate than in the fourth groove 703, that is, the clamping pin is more stable.
The fastener box component 2 is provided with a first dovetail 710, also referred to herein as a stop block 710. The first dovetail 710 may be plugged in the first dovetail groove 701 and may slide in an extension direction of the first dovetail groove 701. The first dovetail 710 is provided with an eighth groove 711. The first dovetail 710 is plugged in the first dovetail groove 701. After the fastener box component 2 is installed in position, the eccentric piece 705 rotates by a particular angle to be partially plugged in the eighth groove 711. The eccentric piece 705 may block a first dovetail 711, to prevent the first dovetail 711 from exiting from the first dovetail groove 701, that is, prevent the fastener box component 2 from being detached. In this way, the fastener box component 2 may be locked to the connecting portion 101. In this embodiment, when the eccentric piece 705 is located in the eighth groove 711, and the clamping pin 707 is located outside the fourth groove 703 and abuts against the step 709. Therefore, when the eccentric piece 705 is located in a state of being locked at the fastener box component 2, a greater force is required to rotate the eccentric piece 705. The fastener box component 2 is locked more stably.
In this embodiment, the first dovetail groove 701 is both an embodiment of a connecting piece and an embodiment of a guide structure; and the first dovetail 710 is both an embodiment of a first alignment structure and an embodiment of a fitting structure. In addition, after the first dovetail 710 is provided with the fourth groove 703, the first dovetail 710 is divided into two convex blocks, constituting an embodiment of a second alignment structure. The eccentric piece 705 is an embodiment of a locking piece.
Embodiment 8
As shown in FIG. 44, a difference between in this embodiment and Embodiment 4 lies in that the fastening member 21 is not installed on the fastener box component 2, but instead is connected to the power member 13 in advance. When the fastener box component 2 is connected to the gun body 1, the power member 13 drives the fastening member 21 to retract into the gun body 1, and the fastener box component 2 moves to be connected to the gun body 1 in the arrow direction. Before the fastener box component 2 is installed on the gun body 1, the power member 13 is driven by power air to drive the fastening member 21 to move upward, to prevent the fastening member 21 from preventing the installation of the fastener box component 2.
The fastening member 21 in another embodiment may also be, for example, independent of the fastener box component 2 as in Embodiment 8, and before the fastener box component 2 is connected to the gun body 1, the fastening member 21 is connected to the power member 13 in advance.
Embodiment 9
As shown in FIGS. 45 and 46, a difference between this embodiment and Embodiment 1 lies in that, in this embodiment, the first pin post 1034 is not arranged on the fastener box component 2. A power portion 103 is not provided with a first pin hole 215. The shape of the convex block 271 has a form of a dovetail, and the third groove 1092 is a dovetail groove. A connection between the fastener box component 2 and the gun body 1 is implemented relying on the fitting between the dovetail groove and the dovetail and the fitting between the first locking hook 107 and the pin shaft 213. The remaining structure is the same as that in Embodiment 1.
Embodiment 10
As shown in FIGS. 47 and 48, the power for fastening in this embodiment is different from that in the foregoing embodiment. A fastener gun with manual fastening is used in this embodiment. As shown in the figure, the gun body 1 comprises a connecting portion 101, a grasping portion 102, a driving portion 103, and a crossbeam 109. The driving portion 103 is provided with an accommodating cavity 301. The accommodating cavity 301 is provided with a sliding block 302 that may slide vertically. The sliding block 302 is provided with a jack 3021. A lever 304 is installed rotatably around the shaft 305. The shaft 305 is fastened in the accommodating cavity 301. The lever 304 is provided with a slide groove 306. The shaft 305 penetrates the lever 304 along the slide groove 306. The size of the slide groove 306 is greater than that of the shaft 305 to enable the lever 304 to be rotatable around the shaft 305 and further movable relative to the shaft 305. One end 3041 of the lever 304 is plugged in the jack 3021 of the sliding block 302 and may move out of the jack 3021. The other end 3042 of the lever 304 extends out of the gun body 1 to facilitate pressing by an operator. The accommodating cavity 301 is provided with a fifth spring 307. One end of the fifth spring 307 abuts against the lever 304, and the other end abuts against the driving portion 103. An elastic sheet 308 is further provided in the accommodating cavity 301. One end of the elastic sheet 308 is fastened, and the other end is connected to the sliding block 302. The sliding block 302 moves upward to enable the elastic sheet 308 to deform to generate an elastic force. The elastic force of the elastic sheet 308 may enable the sliding block 302 to move downward to drive the fastening member 21 for fastening.
During fastening, the other end of the lever 304 is pressed to enable the lever 304 to rotate around the shaft 305. The lever 304 rotates to enable the sliding block 302 to move upward and drive the elastic sheet 308 to deform. The lever 304 rotates to slide to the right relative to the shaft 305. At the same time when the sliding block 302 moves upward, the lever 304 slides to the right until the lever 304 moves out of the jack 3021 of the sliding block 302. The sliding block 302 moves downward under the effect of the elastic sheet 308 to perform fastening. After pressing is released, the lever 304 resets under the effect of the fifth spring 307, and an end portion is inserted in the jack 3021 again.
The solution in any foregoing embodiment may be used for a connection solution between the fastener box component 2 and the gun body 1. As shown in the figures, referring to the connection solution between the fastener box component 2 and the gun body 1 in Embodiment 1, the connecting portion 101 in this embodiment is connected to a second locking hook 310. The second locking hook 310 has a V shape. An end portion of the second locking hook 310 is provided with a hook body (not shown in the figure). The hook body is used to hook the pin shaft 213 on the fastener box component 2. A second torsion spring 312 is further installed on the connecting portion 103. The second locking hook 310 rotates to enable the second torsion spring 312 to deform to generate an elastic force. The elastic force may enable the second locking hook 310 to reset to be kept in a state of hooking the pin shaft 213. During use, the second locking hook 310 hooks the pin shaft 213, and the connecting portion 101 is connected to the fastener box component 2. The second torsion spring 312 enables the second locking hook 310 to be kept in the state. The second locking hook 310 is pushed with a hand to rotate clockwise, and after a hook body 311 unhooks the pin shaft 213, the fastener box component 2 can be removed. In this case, the second torsion spring 312 deforms to generate an elastic force. The elastic force may enable the second locking hook 310 to reset and can help the second locking hook 310 to stably keep hooking at the position of the pin shaft 213.
In this embodiment, the first locking hook 107 and the second locking hook 310 are both locking hooks, and are generally referred to as a locking hook. The first torsion spring 108 and the second torsion spring 312 are respectively an embodiment of a sixth elastic reset device.
The power member 13 has an initial position and an end position during movement. The power member 13 shown in FIGS. 4 and 5 is at the end position. The initial position of the power member 13 is above the end position, and is generally at the top (e.g., further away from the fastener box component as compared to the end position) of the accommodating cavity 1221. The power member 13 moves from the initial position to the end position to drive the fastening member 21 to launch a fastener. As discussed with regard to Embodiment 8, the fastening member 21 may be first connected to the power member 13 before the fastener box component 2 is connected to the gun body 1. The initial positions of the power member 13 and the fastening member 21 are in the gun body 1. Before the fastener box component 2 is connected to the gun body 1, the power member 13 drives the fastening member 21 to move to a position where the occurrence of the fastener box component 2 being prevented from installation can be avoided, and the fastener box component 2 is then connected to the gun body 1. During fastening, the power member 13 carries the fastening member 21 to move from the initial position to the end position to implement fastening.
When the fastening member 21 is first connected to the fastener box component 2 and is then connected to the power member 13, the initial position of the power member 13 overlaps the end position. When the power member 13 is located in the end position, the fastener box component 2 is then connected to the gun body 1 such that the power member 13 is connected to the fastening member 21 at the same time. During fastening, the power member 13 carries the fastening member 21 to move away from the initial position, and then returns to the initial position under the effect of power to implement fastening.
